Increased risk of open-angle glaucoma following chronic rhinosinusitis: a population-based matched-cohort study

Purpose

Anatomically, the eyes and paranasal sinuses are neighboring structures and some studies have mentioned eye disease in conjunction with chronic rhinosinusitis (CRS). However, to the best of our knowledge, no prior research has investigated the risk of developing open-angle glaucoma (OAG) among CRS patients. This study aims to provide an estimated risk of developing OAG among patients with CRS by using a population-based data set in Taiwan.

Methods

This retrospective cohort study used data sourced from the ‘Longitudinal Health Insurance Database 2000''. A total of 15 642 CRS patients were included in the study cohort and 46 926 subjects were randomly extracted as a comparison cohort. A cox proportional-hazards regression analysis was performed to calculate the 5-year risk of subsequently developing OAG following a diagnosis of CRS between the study cohort and the comparison cohort.

Results

The incidence rate of developing OAG over the 5-year follow-up period was 5.45 (95% CI: 4.95–5.98) per 1000 person-years for the study cohort and 2.80 (95% CI: 2.60–3.03) per 1000 person-years for the comparison cohort. After censoring the cases that died over the 5-year period and adjusting for the factors of monthly income, geographic region, hypertension, diabetes, coronary heart disease, hyperlipidemia, and hypothyroidism the hazard ratio for developing OAG over the 5-year period for subjects with CRS to subjects without CRS was 1.73 (95% CI: 1.53–1.96).

Conclusion

We found that those subjects with CRS had a significantly higher risk of developing OAG over the 5-year follow-up period as compared with subjects without CRS.     

Horizontal muscle transposition or oblique muscle weakening for the correction of V pattern?

Purpose

To report and to analyze the efficacy of horizontal rectus muscle transposition and inferior oblique muscle weakening in terms of pattern correction for patients with V pattern.

Methods

The review of the medical files identified 55 patients who had esotropia (ET) or exotropia (XT) with V pattern. The primary outcome measure was the amount of V pattern collapse (Δ).

Results

Of the 55 patients (mean age 22.1±9.5 years), 27 (49.1%) were males and 28 (50.9%) were females. The type of deviations was XT in 30 patients (54.5%) and ET in 25 patients (45.5%). Inferior oblique muscle weakening was performed in 43 (78.2%) patients, whereas horizontal muscle transposition was carried out in 12 (21.8%) patients in addition to recession-resection procedures. The amount of pattern was significantly reduced in both groups (P=0.01 for the horizontal offset group and P<0.01 for the oblique muscle weakening group).

Conclusion

Oblique muscle weakening surgery and horizontal muscle offset are effective in the correction of V pattern when the amount of pattern is under 30Δ.     

Acute post-operative rhinosinusitis following endonasal dacryocystorhinostomy

Purpose

To investigate the incidence and risk factors for acute rhinosinusitis (ARS) following endoscopic dacryocystorhinostomy (EnDCR).

Methods

Retrospective single-surgeon interventional case series, including 196 consecutive patients undergoing 203 endonasal DCR, with clinical and radiological evidence of nasolacrimal duct or common canalicular obstruction. Pre-operative lacrimal and sinonasal clinical assessment and imaging, intraoperative endoscopic video recording, and post-operative clinical and endoscopic findings were analysed for cases of ARS occurring within the first 4 weeks following DCR among patients with and without a past history of chronic rhinosinusitis (CRS). Surgical complications and outcomes at 12 months and management of ARS are reported.

Results

Three patients (1.5%) developed ARS within the first 5 post-operative days, none of which had experienced peri-operative complications and all had a past history of CRS. The rate of CRS in this cohort of 196 patients was 10.2% (n=20), of which 15% (n=3) developed ARS, although none had symptoms of CRS at the time of surgery; one had undergone previous sinus surgery. Presenting symptoms of ARS included facial pain, tenderness over the affected sinus, and nasal discharge; all patients responded to oral antibiotic therapy.

Discussion

The rate of ARS following EnDCR was 1.5%. In those with a prior history of CRS, it was 15% (P=0.009). ARS developed within the first post-operative week among patients with a past history of CRS, who were asymptomatic at the time of surgery, and responded to oral antibiotics. CRS may be a risk factor for the development of post-operative ARS.     

Comparison of two- and three-point sutures for advancing the levator aponeurosis in Asian eyelids

Purpose

To compare the functional and cosmetic outcomes of two- and three-point sutures for advancing the levator aponeurosis in blepharoptosis surgery on Asians.

Patients and methods

This retrospective study examined 60 Asian patients with blepharoptosis who had undergone advancement of the levator aponeurosis: 34 patients (46 eyelids) had ptosis correction using the two-point suture technique and 26 patients (41 eyelids) had ptosis correction using the three-point suture technique. The postoperative marginal reflex distance (MRD1), lid height difference, and eyelid contour were evaluated.

Results

Twenty-seven (79.4%) of the 34 patients in the two-point group and 19 (73.1%) of 26 patients in the three-point group had a postoperative MRD1 of 2–4 mm, lids within 0.5 mm of each other, and a satisfactory eyelid contour; this difference was not significant. The rate of reoperation did not differ significantly between the two groups.

Conclusion

Two- and three-point sutures for advancing the levator aponeurosis were equally effective for correcting blepharoptosis in Asians.     

The Royal College of Ophthalmologists' National Ophthalmology Database study of cataract surgery: report 1, visual outcomes and complications

Aims

To describe the outcomes of cataract surgery in the United Kingdom.

Methods

Anonymised data on 180 114 eyes from 127 685 patients undergoing cataract surgery between August 2006 and November 2010 were collected prospectively from 28 sites. Outcome measures included intraoperative and postoperative complication rates, and preoperative and postoperative visual acuities.

Results

Median age at first eye surgery was 77.1 years, 36.9% cases had ocular co-pathology and 41.0% patients underwent cataract surgery on both eyes. Preoperative visual acuity was 0.30 logMAR or better in 32.0% first eyes and 47.7% second eyes. Postoperative best-measured visual acuity was 0.00 and 0.30 logMAR or better in 50.8 and 94.6% eyes without ocular co-pathology, and 32.5 and 79.9% in eyes with co-pathology. For eyes without co-pathology, postoperative uncorrected distance visual acuity was 0.00 and 0.30 logMAR or better in 27.3 and 80.9% eyes. Posterior capsule rupture or vitreous loss or both occurred in 1.95% cases, and was associated with a 42 times higher risk of retinal detachment surgery within 3 months and an eight times higher risk of endophthalmitis.

Conclusion

These results provide updated data for the benchmarking of cataract surgery. Visual outcomes, and the rate of posterior capsule rupture or vitreous loss or both appear stable over the past decade.     

Relationship between paravascular abnormalities and foveoschisis in highly myopic patients

Purpose

To describe the prevalence of paravascular abnormalities in highly myopic patients and its relationship with myopic foveoschisis (MF).

Methods

Cross-sectional study of 250 highly myopic eyes. All of the patients underwent a complete ophthalmologic examination that included optical coherence tomography .

Results

Optical coherence tomography images showed 170 eyes (68%) with paravascular microfolds (PM), 121 eyes (48.4%) presented paravascular retinal cysts (PC), and 35 eyes (14%) with paravascular lamellar holes . All the eyes with PCs had PMs. Out of the 250 eyes, 48 (19.2%) had paravascular retinoschisis (PR). All the eyes (100%) with PR had paravascular cysts and PMs. Sixteen eyes (6.4%) had foveoschis. The spherical equivalent (P<0.00), PR (P=0.01), and the presence of tractional structures (P<0.00) were associated with increased risk for foveoschsis in the multivariate study.

Conclusions

PMs were the lesions most often observed in the paravascular area in highly myopic eyes. MF would be a result of the action of different forces (intra- and extra-ocular forces), specially tractional structures, on precursor lesions (paravascular cyst and paravascular restinoschisis). Further studies are needed to confirm these results.     

Visual and anatomic outcomes of golf ball-related ocular injuries

Aims

To investigate the characteristics and prognoses of golf ball-related ocular injuries (GROIs) using standardized terminology, classification, and scoring systems.

Methods

Twenty-two GROI patients were assessed using the Birmingham Eye Trauma Terminology, Ocular Trauma Classification Group (OTCG) classification, and Ocular Trauma Score. Globe preservation and final visual acuity (FVA) were assessed according to the injury severity categorical designation.

Results

Fourteen patients were injured on golf courses and eight on driving ranges. Nine patients (40.9%) had open-globe injuries (five ruptures (22.7%), four penetrating injuries (18.2%)). All rupture cases required enucleation, whereas penetrating injury cases did not (the FVA ranged from 20/100 to no light perception). In open-globe injuries, wearing glasses protected against rupture (P=0.008). Thirteen patients sustained closed-globe injuries that were accompanied by lens subluxation (38.5%), choroidal rupture (30.8%), macular commotio retinae (38.5%), and traumatic optic neuropathy (7.7%). Twelve (54.5%) patients had orbital wall fractures. The mean number of related surgeries required was 1.5±1.7 across all patients.

Conclusion

Eyes with GROIs had devastating FVA and globe preservation status, especially those with open-globe injuries. Observing golf rules and improving driving-range facilities are essential for preventing GROIs. Protective eyewear may reduce ocular damage from GROIs, especially globe rupture.     

Prevalence of glaucoma in patients with moderate to severe obstructive sleep apnea: ocular morbidity and outcomes in a 3 year follow-up study

Purpose

This study was conducted to investigate the prevalence and progression of glaucoma in patients receiving treatment for obstructive sleep apnea (OSA). We also investigated whether there is an association between severity of OSA and the incidence of glaucoma.

Methods

A total of 39 patients aged >30 years who had been diagnosed with moderate and severe OSA in the sleep clinic at Hamad General Hospital were assessed for the presence of glaucoma. The severity of OSA was graded as mild, moderate, or severe based on American Association of Sleep Medicine (AASM) criteria using the apnea hypopnea index. Before enrollment, all patients underwent a complete ophthalmic examination including serial visual field tests, optical coherence tomography (OCT) with fundus photographs, and pachymetry. Enrolled patients were followed up in the ophthalmology outpatient clinic and sleep clinic for a period of 3 years.

Results

Examinations found that 8 (20.5% 95% confidence interval (CI) 9.9–37%) of the 39 patients with OSA had glaucoma. Six (75% 95% CI 36–96%) of these patients had normal-tension glaucoma (NTG) and two (25% 95% CI 4.5–64.4%) patients had high-tension glaucoma. Among the 27 patients with severe OSA, 7 (25.9% 95% CI 8–34%) had glaucoma, and among 12 patients with moderate OSA, 1 (8.3% 95% CI 0.1–15%) had glaucoma. During the course of follow-up, two patients who previously did not have glaucoma were reclassified as NTG and two patients with glaucoma deteriorated. A higher prevalence of glaucoma in the severe OSA group compared with the moderate OSA group was found, albeit a statistically significant difference could not be attained (P=0.4).

Conclusions

Our study showed that severe OSA is an important risk factor for developing glaucoma. Adequate treatment of OSA, along with optimal ophthalmic care, resulted in better control of glaucoma.     

Botulinum toxin injections combined with or without sodium hyaluronate in the absence of electromyography for the treatment of infantile esotropia: a pilot study

Objective

To evaluate the feasibility and safety of a revised technique of botulinum toxin type A (BTA) injections for the treatment of infantile esotropia.

Methods

Forty-seven patients with infantile esotropia were randomly divided into two groups. In group A, 23 cases were treated with a bilateral injection of 2.5–3.75 U BTA combined with sodium hyaluronate (SH) to the medial rectus muscle. In group B, 24 cases were treated with a bilateral injection of 2.5–3.75 U BTA solution alone to the medial rectus muscle. Electromyography was not used in the study. All patients received one injection and were evaluated 2 weeks, 3 months, and 6 months following injection.

Results

The measured changes between groups A and B included the frequencies of good alignment 6 months after injections (30.4% vs 37.5%), complicated ptosis (2.2% vs 20.8%), and vertical deviation (2.2% vs 2.1%).

Conclusion

BTA injections combined with or without SH in the absence of electromyography demonstrated effectiveness and feasibility in the treatment of infantile esotropia. A relative decrease in the frequency of complicated ptosis resulted from injections of BTA+SH.     

Evaluation of the retinal nerve fibre layer and ganglion cell complex thickness in pituitary macroadenomas without optic chiasmal compression

Purpose

The aim of this prospective study was to measure the thickness of the circumpapillary retinal nerve fibre layer (cpRNFL) and the ganglion cell complex (GCC) using spectral domain optical coherence tomography (SD-OCT) in a cohort of consecutive de novo patients with pituitary macroadenomas without chiasmal compression.

Patients and methods

Twenty-two consecutive patients with pituitary macroadenoma without chiasmal compression (16 men, 6 women, aged 45.2±14.6 years, 43 eyes) entered the study between September 2011 and June 2013. Among them, 31.8% harboured a growth hormone-secreting pituitary adenoma, 27.3% a prolactin-secreting pituitary adenoma, 27.3% a corticotrophin-secreting pituitary adenoma, and 13.6% a non-secreting pituitary tumour. Eighteen subjects (nine females, nine males, mean age 36.47±6.37 years; 33 eyes) without pituitary adenoma, with normal ophthalmic examination, served as controls. In both patients and controls, cpRNFL and GCC thicknesses were measured by SD-OCT.

Results

Patients were significantly older (P=0.02) than controls. Best corrected visual acuity, intraocular pressure, colour fundus photography, and automatic perimetry test were within the normal range in patients and controls. Conversely, cpRNFL (P=0.009) and GCC (P<0.0001) were significantly thinner in patients than in controls. The average GCC (r=0.306, P=0.046) significantly correlated with the presence of arterial hypertension. OCT parameters did not differ significantly between patients with a tumour volume above the median and those with a tumour volume below the median.

Conclusion

Pituitary macroadenomas, even in the absence of chiasmal compression, may induce GCC and retinal nerve fibre layer thinning. SD-OCT may have a role in the early diagnosis and management of patients with pituitary tumours.     

Periodic acid–Schiff staining demonstrates fungi in chronic anterior blepharitis

Purpose

To evaluate the presence of fungi in patients with chronic anterior blepharitis with periodic acid–Schiff (PAS) staining of the eyelashes in addition to the conventional methods of fungal cultures and direct microscopy.

Methods

Nineteen patients with chronic anterior blepharitis of seborrheic or mixed seborrheic/staphylococcal type and 11 healthy age- and sex-matched controls were included in this prospective, nonrandomized, cross-sectional study. Blepharitis was diagnosed based on clinical evidence of greasy scales between the cilia, lid margin erythema, conjunctival hyperemia, telangiectasia, thickening, or irregularity of the eyelid margins by slit-lamp biomicroscopy. Eyelash samples were obtained by epilation with a sterile forceps and evaluated with PAS staining, fungal cultures, and direct microscopy.

Results

We demonstrated fungal elements with PAS staining in 79% of the blepharitis group (hyphae and/or spores) and 18% of the control group. The difference was statistically significant (P=0.002). Four patients in the blepharitis group (21%) had positive cultures for fungi. The isolated fungi were Penicillium species (2 cases), Candida species (1 case), and Trichophyton verrucosum (1 case). Direct microscopic examination revealed Demodex mites in 42.1% of the blepharitis group. No culture growth or Demodex mites were observed in the control group.

Conclusions

We have shown fungi with PAS staining in the majority of patients with chronic anterior blepharitis. Further controlled studies are necessary to clarify the role of fungi in the etiopathogenesis of blepharitis.     

The effects of Helicobacter pylori infection on intraocular pressure in anterior uveitis

Purpose

We investigated the influence of H. pylori infection on intraocular pressure (IOP) in anterior uveitis patients to clarify whether H. pylori infection is related to high IOP in anterior uveitis.

Methods

In this prospective study, 165 Korean anterior uveitis patients were examined. All patients underwent serological analysis to identify the cause of uveitis, including the presence of H. pylori infection by enzyme-linked immunosorbent assay. Serological values were compared between patients with and without high IOP.

Results

Seropositivity for H. pylori was 69.70% of patients with high IOP and 38.38% of patients with normal IOP (P<0.01).

Conclusion

This study suggests that H. pylori infection is associated with high IOP in anterior uveitis.     

Choroidal thickness in regressed retinopathy of prematurity

Purpose

To compare choroidal thickness in patients with regressed retinopathy of prematurity (ROP) with healthy controls using enhanced depth imaging optical coherence tomography (EDI OCT)

Methods

Twenty-four children and young adults (41 eyes) with regressed ROP≥stage 3 had undergone EDI OCT with Spectralis FD-OCT as part of their clinical record. Their refraction, best-corrected visual acuity, and ophthalmoscopic findings were recorded. Corresponding data was collected prospectively from 33 healthy controls (58 eyes) who had been born at term. Choroidal thickness was measured independently by two observers subfoveally and at 1500 μm nasal and temporal to the fovea using EDI OCT.

Results

Mean subfoveal choroidal thickness, adjusted for refraction, was 271.1 μm (95% CI, 247.8–294.5) in the ex-ROP group, which was significantly thinner than 327.4 μm (95% CI, 293.8–360.9) in controls (P=0.008). Similarly, mean adjusted temporal choroidal thickness was 257.2 μm (95% CI, 240.2–274.2) in ex-ROP''s vs 320.5 μm (95% CI, 288.6–352.3) in controls (P=0.001). There was no statistically significant difference in the nasal measurement. In the ex-ROP group, there was no significant correlation between subfoveal choroidal thickness and gestational age (r_s=0.16, P=0.46) or birthweight (r_s=0.03, P=0.90). In eyes without copathology in addition to regressed ROP (29 eyes, 19 patients), there was no significant correlation between subfoveal choroidal thickness and visual acuity.

Conclusions

Our findings of thinner subfoveal and temporal macular choroidal thickness in regressed ROP support the case for choroidal involvement in the pathogenesis of this condition.     

Intravitreal bevacizumab for proliferative diabetic retinopathy with new dense vitreous hemorrhage after full panretinal photocoagulation

Purpose

To evaluate the efficacy and safety of intravitreal bevacizumab (IVB) injections for the treatment of proliferative diabetic retinopathy (PDR) with new dense vitreous hemorrhage (VH) after previous full panretinal photocoagulation (PRP).

Methods

Prospective study of consecutive PDR with prior complete PRP patients, who presented with new dense VH, were treated with IVB injection. Complete ophthalmic examination and/or ocular ultrasonography were performed at baseline and 1, 6, and 12 weeks and 6, 9, and 12 months after the first injection. Reinjection was done in non-clearing and recurrent VH.

Results

Eighteen eyes of 18 patients, mean age 47.7±12.69 years were included. In all, 14 (77.78%) patients had type 2 diabetes mellitus. Systemic hypertension and dyslipidemia were the most common systemic diseases. All cases were phakic eye with previous complete PRP. Patients received 1.6±0.42 intravitreal injections over a 12-month period. VH cleared completely in 7 (38.89%), 9 (50%), and 13 (72.22%) eyes after 6 weeks, 6 months, and 12 months, respectively. Re-bleeding, however, occurred in 10 (56%) eyes during the follow-up period, and 5 (28%) eyes still had residual VH at the last visit. Statistically significant visual gain was observed in 9 (50%) eyes. Unfortunately, 2 (11%) eyes had severe visual loss because of the tractional retinal detachment (TRD). Mild ocular complication was detected in one patient.

Conclusion

IVB injection had good efficacy and safety for treatment of new VH in patients with PDR and prior complete PRP. This procedure may be especially relevant for diabetic patients at high-risk for surgical intervention.     

Clinical outcome of advanced squamous cell carcinoma of the conjunctiva

Background

To evaluate the outcome of surgical management of advanced squamous cell carcinoma (SCC) of the conjunctiva (American Joint Committee Cancer—classification >III) and the rate of recurrences after treatment during follow-up. Second, to investigate the incidence of orbital exenteration during follow-up.

Methods

Thirty-eight cases with SCC >grade T3 AJCC were retrospectively analysed at a University Eye Hospital Munich. Tumour stage, type of treatment, follow-up time, risk factors and—if present—recurrence were documented.

Results

The mean follow-up was 24.2 months (22.3–71 months). The most frequent surgical procedure was local tumour excision (n=25 patients, 71%). Orbital exenteration was performed in 10 patients (28%). Twenty patients (57%) did not show a progressive disease during follow-up. Of the patients with primary local excision, 13 (52%) had recurrence. Average time to recurrence for all treated patients was 24 months in the mean (minimum 4 months, maximum 68 months, SD, 22). Patients following orbital exenteration had recurrence of disease in 20% (n=2). None of the patients with primarily local tumour excision required an orbital exenteration.

Conclusion

Advanced-stage SCC can be treated surgically. An extensive surgical approach is sometimes inevitable. Patients with surgical excision of advanced-stage disease should be reviewed closely as recurrences may occur and even after more than 5 years. However, on early detection, most of these recurrences can be handled by local excision.     

Cicatricial changes in ocular pemphigus

Purpose

To describe the clinical characteristics of ocular involvement in patients with pemphigus at an ophthalmological referral center.

Methods

A retrospective review was conducted on patients with the immunopathological diagnosis of pemphigus examined between 1 January 2000 and 1 April 2010. Uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BCVA), ocular symptoms, and ocular surface inflammatory and scarring changes were assessed.

Results

A total of 15 patients were identified, with a mean age of 68.27±14.35 years, and 80% (n=12) were female. Extraocular involvement was reported in one patient. All of the eyes showed cicatricial changes in the conjunctiva. In all, 6 eyes (20%) were classified as stage I; 12 eyes (40%) as stage II; 10 eyes (33%) as stage III; and 2 eyes (7%) as stage IV. A statistically significant association was found between BCVA and the severity of ocular involvement. The mean BCVA logMAR was 1.66 (20/914), with a range from logMAR 0 (20/20) to logMAR 4 (NLP). Other ocular diseases were found in 8 (53.3%), systemic diseases in 10 (66.7%), and the use of pemphigus-inducing drugs in 10 patients (66.7%).

Conclusions

The present report represents the largest series of ocular involvement in pemphigus confirmed by immunopathology. The clinical manifestations varied from conjunctival hyperemia to corneal scarring and perforation. There was a strong association between scarring changes and low BCVA. Ocular and systemic diseases as well as the use of pemphigus-inducing drugs may predispose to ocular cicatricial changes observed in this series.     

Incidence of deepening of the upper eyelid sulcus in prostaglandin-associated periorbitopathy with a latanoprost ophthalmic solution

Purpose

Among some local side effects of prostaglandin-associated periorbitopathy (PAP), deepening of the upper eyelid sulcus (DUES) is the most prominent clinical feature, and is one of the most significant adverse cosmetic events. Here, we prospectively investigated the incidence of DUES in Japanese open-angle glaucoma patients initially treated with latanoprost (Xalatan 0.005%) ophthalmic solution.

Methods

This was an open-label prospective study. Facial photographs and subjective reports of the recognition of DUES were obtained at the beginning of latanoprost treatment and at 2, 4, and 6 months thereafter. Intraocular pressure (IOP) was measured at three consecutive visits before and after treatment with latanoprost. The incidence of DUES was evaluated objectively by three blinded investigators who compared the series of photographs.

Results

A total of 52 eyes of 52 newly diagnosed open-angle glaucoma Japanese patients (28 males, 24 females) were evaluated. The objective rate of DUES was 1/52 (2% 95% CI 0.05 to 10.7%) at 2 months, 2/52 (4% 95% CI 0.5 to 13.9%) at 4 months, and 3/52 (6% 95% CI 1.2 to 16.9%) at 6 months. During this period, no patient self-reported an occurrence of DUES. Mean IOPs before and after treatment were 16.5±2.9 and 13.8±3.0 mm Hg, respectively. Latanoprost reduced the IOP significantly (P<0.0001, paired t-test).

Conclusions

Latanoprost caused DUES rarely and had a robust IOP-lowering effect in Japanese glaucoma patients.     

Long-term efficacy of latanoprost in primary congenital glaucoma

Purpose

To investigate the success (glaucoma control) of latanoprost therapy of primary congenital glaucoma (PCG) and factors affecting the long-term outcome.

Methods

Patients with PCG treated with latanoprost were re-examined. At study visit and from clinical charts, we evaluated: intraocular pressure, length of glaucoma control with latanoprost, need of further medication or glaucoma surgery, systemic and topical side effects. Multivariate analysis was used to test factors related to the final outcome of the treatment.

Results

Eighty-one eyes of 44 patients with PCG, and 42 eyes of 29 patients with previous glaucoma surgery, had received latanoprost therapy. In the first group, a success (glaucoma control by latanoprost therapy) was found in 24 eyes (29.6%), whereas 57 eyes (70.4%) had received surgery (45 eyes (55.6%) in the first year); among the eyes with previous surgery, a success was found in 12 eyes (28.6%), 13 eyes (31%) required an additional therapy, and 17 eyes (40.5%) had received further glaucoma surgery. No patient discontinued the treatment because of side effects. Factors related to the failure of the latanoprost treatment were: the high score of severity of glaucoma (P=0.014) and low age at PCG presentation (P=0.042).

Conclusions

Long-term treatment with latanoprost is effective in about 30% of the eyes; factors related to failure were severe glaucomatous alterations, and young age at PCG presentation.     

Stability and safety of MA50 intraocular lens placed in the sulcus

Purpose

To describe the safety and stability of sulcus placement of the MA50 intraocular lens (IOL).

Patients and methods

Consecutive patients with MA50 IOLs placed in the sulcus at the University of Iowa Hospitals and Clinics, Iowa City, Iowa, USA, from 1997 to 2012 were identified. Inclusion criteria included patients with over 4 weeks of follow-up data. AEL was compared with incidence of IOL decentration using at two-tailed Student''s t-test.

Results

Fifty eyes of 49 patients meeting the inclusion criteria were identified. Four weeks post-operatively, the average best-corrected visual acuity was 20/30. IOL decentration occurred in 14% of patients; patients with decentered IOLs had a significantly longer average AEL (25.37 mm) than patients whose IOL remained centered (23.94 mm, P=0.017). Other complications included uveitis-glaucoma-hyphema syndrome (12%), iritis (8%), and glaucoma (6%). There were no cases of pigment dispersion syndrome or need for lens exchange. Twelve eyes (24%) had intra-operative optic capture by the anterior capsule, none of which had post-operative decentration.

Conclusion

The MA50 IOL is a reasonable, stable option for placement in the sulcus, with a low-risk profile; however, in eyes with longer AEL and presumably larger anterior segment, surgeons should consider placing an IOL with longer haptic distance than the MA50 to maintain centration. Optic capture of the MA50 IOL by the anterior capsule should be considered for longer eyes, as it is protective against decentration.
