Outcomes of Cataract Surgery in Ocular Cicatricial Pemphigoid

Abstract

Purpose: To report the outcomes of cataract surgery in ocular cicatricial pemphigoid (OCP). Setting: L. V. Prasad Eye Institute, Hyderabad, India. Design: Retrospective, interventional case series.

Methods: Patients diagnosed with OCP who had undergone cataract surgery were included. Staging of disease, type of surgery, pre- and postoperative best-corrected visual acuity (BCVA), and number and duration of topical and systemic medications were recorded. Complications and any exacerbation or worsening of disease were noted.

Results: Nine eyes of 7 patients (3 male, 4 female) were included in the study, with mean age of 60.44?±?2.6 years (range 56–64 years). Follow-up ranged from 6 months to 10 years (mean 52.9?±?46.25 months). Surgery performed was extracapsular cataract extraction with posterior chamber intraocular lens implantation (n?=?5) or phacoemulsification with posterior chamber intraocular lens implantation (n?=?4). Best-corrected visual acuity improved by more than 2 lines in 6 of 9 (66.67%) eyes, which remained stable till the last follow-up. Three eyes had no visual improvement due to corneal scar in 2 patients and preexisting posterior staphyloma in 1 eye. Disease progression was noted in 2 of 9 operated eyes by one stage at the end of 1 year.

Conclusion: In this series, cataract surgery could be safely performed with no major intra- or postoperative complications. While the surgical intervention itself was not associated with acute exacerbations of inflammation, progression of disease was noted in some cases over time. In spite of ongoing disease, cataract surgery in OCP was associated with stable visual outcomes.     

独眼白内障超声乳化人工晶状体植入术的临床观察

目的:探讨独眼白内障患者超声乳化吸出及人工晶状体植入手术的效果。方法:对44例独眼白内障患者行超声乳化吸出及人工晶状体植入手术治疗。观察术后3mo术眼的视力;观察术中、术后并发症发生情况。随访3～12(平均4.2)mo。结果:术后视力均有不同程度提高,术后3mo视力<0.1者2例(4.5%),0.1～0.25者8例(18.2%),0.3～0.5者18例(40.9%),0.6～1.0者16例(36.4%)。脱残率77.3%,脱盲率95.5%。术中并发症:虹膜咬伤1例,前房少量出血1例,切口处虹膜脱出1例。术中并发症的发生率为6.8%。术后并发症:早期角膜水肿5例(11.4%),虹膜睫状体炎2例,术后早期眼压升高1例,术后1d前房积血1例,后囊膜混浊2例。无眼内炎及视网膜脱离等严重并发症。结论:对于独眼白内障患者,只要采取认真负责的态度,充分做好各种准备,超声乳化吸出加人工晶状体植入手术是安全和有效的,但对术者的技术及心理素质要求较高。

Complications of surgery for epiretinal membranes

· Purpose: Surgery has been successful in removing epiretinal membranes (ERM) from the macula, allowing some improvement in vision in 80–90% of patients; however, complications are relatively frequent. We conducted a retrospective study to evaluate the rate of peri- and postoperative complications and their influence on functional outcome of eyes having been operated on for ERM. · Material and methods: Preoperative findings, intraoperative and postoperative complications as final results of 70 consecutive cases of idiopathic or secondary ERM operated on by the same retina surgeon were analyzed. · Results: In all cases the ERMs were succesfully removed from the fovea. The mean visual acuity (VA) increased from 0.34±0.2 to 0.54±0.31 (P<0.05) postoperatively. Idiopathic and secondary ERM both showed significant improvement after surgery. Complications included intraoperative hemorrhage and retinal tears and postoperative progressive nuclear sclerosis, retinal tears causing detachments, macular edema and retinal pigmentary epitheliopathy. Final VA was not significantly different from the mean after complications, apart from when retinal detachments involved the macular area. · Conclusions: Performing surgery for ERM is worthwhile in eyes with major decreased VA and in eyes with metamorphopsia but only moderately reduced vision. Postoperative complications are frequent but can usually be managed successfully. Of them, only retinal detachment has a negative effect on the final functional outcome.

抗青光眼滤过术后白内障摘除术对眼内压长期影响的临床观察

目的探讨抗青光眼滤过术后白内障摘除术对眼内压的长期影响。方法对抗青光眼滤过术后白内障患者69例69眼随机分为三组,分别采用颞侧角巩膜缘切口白内障囊外摘除及人工晶状体植入术(简称ECCE组)(18例18眼)、颞侧角巩膜缘隧道切口超声乳化白内障吸除及人工晶体植入术(简称角巩膜缘超声乳化组)(25例25眼)和上方透明角膜切口超声乳化白内障吸除及折叠式人工晶体植入术(简称透明角膜超声乳化组)(26例26眼),术后平均随访26个月,分别观察眼压和视力并进行比较。结果ECCE组、角巩膜缘超声乳化组、透明角膜超声乳化组术后最后一次随访时平均眼压升高分别为2.75mmHg,1.82mmHg和1.68mmHg,与术前比较,差异均无统计学意义(>0.05);视力改善分别为12眼(70.6%)、23眼(92.0%)和24眼(92.3%);ECCE组与角巩膜缘超声乳化组和透明角膜超声乳化组比较,术后效果低于两种超声乳化组,差异有统计学意义(<0.05),两种超声乳化组间比较,差异无统计学意义(>O.05)。结论抗青光眼滤过术后三种白内障摘除术术后眼压均可有效控制,视力改善,超声乳化白内障吸除术尤其是经透明角膜切口折叠式人工晶体植入术术后长期对眼压影响小,视力恢复快,是目前此类白内障手术的最佳术式。     

Transscleral suture fixation of posterior chamber intraocular lenses in children under 3 years

 · Background: Children who have undergone lentectomy for congenital or traumatic cataract do not have adequate capsular support for secondary posterior chamber intraocular lens (PC-IOL) implantation and thus will become severely amblyopic if contact lens intolerance occurs. In order to prevent amblyopia we fixed PC-IOLs by transscleral sutures in three children younger than 3 years. Clinical outcome, visual acuity and course of refraction were studied. · Methods: Four eyes of three children with contact lens intolerance were operated. Posterior chamber lenses (PC-IOL) were sutured in the ciliary sulcus by transscleral sutures. Two children had monocular traumatic cataract and one child underwent surgery on both eyes for congenital cataract. To allow adjustment of refraction in situ without removing the primarily implanted and transsclerally fixed PC-IOL we used the piggyback intraocular lens system for implantation. · Results: Visual acuity improved in all four eyes. The two children with traumatic cataract achieved visual acuity of 0.7 and 1.0, respectively, and stereopsis. No complications related to the technique of transscleral suture fixation of the PC-IOL were observed. Postoperative changes in refractive power were caused by a myopic shift between –1.0 D and –9.0 D. Follow-up was 25–70 months. · Conclusion: Transscleral suture fixation of PC-IOLs did not cause specific complications during follow-up of up to 70 months. This technique offers an important option for the correction of an aphakic refractive error which cannot be corrected otherwise. In future the piggyback intraocular lens system may help to rather atraumatically correct postoperative changes in refractive power.

Predictive value of pattern VEP, pattern ERG and hole size in macular hole surgery

· Objective: To describe pattern-reversal visual evoked response (PRVEP) and pattern electroretinogram (PERG) parameters in eyes with macular hole and their value for predicting postoperative visual outcome. · Methods: Prospectively we studied 27 eyes (27 patients) with a full-thickness macular hole. Preoperatively the hole and rim were measured and the PRVEP and PERG were recorded. The preoperative parameters were correlated with postoperative visual outcome. · Results: The macular hole was closed in 26 of 27 eyes. Sixteen eyes (59%) had an increase in visual acuity (VA) of two lines or more, 10 eyes (37%) remained within one line of preoperative VA and 1 eye (4%) had a decrease in VA of two lines. Duration of symptoms was negatively correlated with preoperative VA (R=–0.547, P=0.0038) and postoperative VA (R=–0.519, P=0.0065) and positively correlated with hole area (R=0.533, P=0.0061) and rim area R=0.633, P=0.0009). Only the PRVEP P100 latency of the 10′ check size and the PERG N35 latency were significantly associated with visual outcome (P=0.022 and P=0.042 respectively). · Conclusions: There was no association of either hole or rim size with postoperative visual outcome. Preoperative electrophysiology, however, is useful as a prognostic tool. Utilization is limited to the use of latency parameters of the response and is dependent on the check size of the stimulus.

Abstract：

Objective To evaluate the clinical effect of the scleral tunnel incision in extracapsluar cataract extraction(ECCE)in leprosy patients. Methods Fifty-seven eyes of 57 cataract blind leprosy patients screened by dermatologists underwent the scleral tunnel incision in ECCE, including 39 eyes of complicated cataract and 18 eyes of age-related cataract retrospectively. The clinical effects were evaluated at 1 year after surgery compared with the homochronous surgery outcome of 63 eyes of 63 age-related cataract patients. Results Vitreous loss and iris trauma et cetera occurred during ECCE in leprosy patients, and also elevated intraocular pressure et cetera occurred after ECCE. The best postoperative visual acuity(VA)was better than 0.4 in 38.5% patients in the complicated cataract and in 72.2% in the age-related cataract of leprosy patients. The better VA was from 0.1 to 0.3 in 46.2% and 27.8% in the two groups, respectively, and less than 0.1 in 15.4% and 0% in the two groups, respectively. Among the 29 cases whose best VA were poorer than 0.3 in the leprosy patients, 24 cases had preoperative chronic uveitis, which seemed to be the primary reason for the poor postoperative VA in leprosy patients. Chronic uveitis and secondary glaucoma etc were the postoperative complications of ECCE in leprosy patients. Conclusions Scleral tunnel incision in extracapsluar cataract extraction is safe and effective when performed in leprosy with complicated cataract. Chronic uveitis need to be controlled pre- and postoperation.

A prospective randomized comparison of two techniques of combined cataract – glaucoma surgery

· Background: Small-incision cataract surgery combined with trabeculectomy offers new options for surgical treatment of patients with glaucoma and cataract. The purpose of this prospective randomized study was to compare the efficacy and safety of two different techniques of combined surgery: a one-site and a two-site approach. · Methods: Fifty eyes of 50 patients were included in this study. Twenty-five patients were randomly assigned to the one-site procedure and 25 patients to the two-site procedure. The one-site approach consisted of a superior tunnel phacoemulsification under a scleral flap with subsequent trabeculectomy. The two-site approach included a temporal corneal phacoemulsification combined with a separate-incision superior trabeculectomy. · Results: The preoperative mean intraocular pressure (IOP) of 29.8±4.9 mmHg dropped significantly to 15.9±3.2 mmHg. The mean follow-up time was 19±4.3 months (range 4–25 months). The reduction of IOP was more pronounced in the two-site group (50.1%) than in the one-site group (43%), but the difference was not statistically significant. Patients needed 2.2±1.7 antiglaucomatous medications preoperatively vs 0.52±1.39 postoperatively. Three patients (6%) required needling of encapsulated bleb, and two patients underwent a reoperation to control IOP. Mean visual acuity improved from 0.14±0.36 to 0.38±0.30 postoperatively. The most common complications after combined surgery were fibrinous exudation (24%) and hyphema (12%). · Conclusion:Both techniques of combined cataract and glaucoma surgery proved to be efficient and safe procedures to control IOP and to improve visual acuity. The reduction of IOP did not differ between the one-site approach and the two-site approach. Received: 2 February 1999 Revised version received: 12 April 1999 Accepted: 13 April 1999     

Results of congenital cataract surgery with and without intraocular lens implantation in infants and children

Background

Operations for congenital cataract in children in the past had resulted in aphakia. Improvement in surgical tools and techniques as well as in intraocular lens (IOL) implantation has led to correction of the aphakia by IOL implantation. We report the outcome of cataract surgery with and without IOL on these children in our institution between 1991–2008.

Methods

In this retrospective cohort study, the medical records of all children who underwent surgery for congenital cataract were reviewed. The final study group included 144 children (218 eyes). Postoperative visual acuity (VA) was tested either by Teller Acuity Cards (in preverbal children) or by the Snellen chart. Data on VA status and postoperative complications were retrieved.

Results

Patients with bilateral cataract had better postoperative VA than patients with unilateral cataract (logMAR 0.559?±?0.455 vs. 0.919?±?0.685, respectively, P?<?0.001). Children who underwent IOL implantation had better postoperative VA than those who did not, but the type of surgery had no significant effect after correction for the child’s age at surgery (P?=?0.346). Secondary cataract occurred more frequently in the extra-capsular cataract extraction (ECCE)?+?IOL implantation group than in the ECCE only group (20.6 % vs. 8.3 %, respectively, P?=?0.018).

Conclusions

Patients with bilateral cataract had better postoperative VA compared with those with unilateral cataract. The type of surgery had no effect on final VA, but there was a higher rate of secondary cataract in the ECCE + IOL patients compared to the ECCE only patients.     

先天性白内障合并小角膜的眼部表现及治疗

目的：探讨小角膜合并先天性白内障患者的眼部临床表现、手术治疗时机及疗效。

方法：回顾性分析2000-01/2012-12在天津医科大学眼科中心接受治疗的先天性白内障合并小角膜患者11例18眼的临床资料,术前检查包括角膜直径(<9.5mm)、眼部异常和全身异常,术后随访至少1a,评价术后视力和并发症等。

结果：患者11例中有先天性白内障家族史4例,18眼中合并虹膜缺损6眼,眼球震颤18眼,原始玻璃体动脉残留1眼。对11例18眼患者施行三种手术方案：(1)行囊外白内障摘除术(extra capsular extraction of cataract, ECCE)者5眼;(2)Ⅰ期行ECCE,Ⅱ期行人工晶状体植入术(posterior chamber intraocular lens,PC-IOL)者4眼;(3)Ⅰ期行ECCE联合PC-IOL植入者9眼。术后患者视力均有明显改善,18眼术后最佳矫正视力0.145±0.0958(0.01～0.20)。ECCE术中并发症主要为后囊破裂1眼,术后并发症主要为后发性白内障10眼,继发性青光眼2眼。

结论：先天性白内障合并小角膜常伴发虹膜、脉络膜缺损,眼球震颤等合并症,人工晶状体的植入能明显提高患者视力,但术中应注重防范角膜损伤、后囊破裂等并发症,术后加强管理,特别是眼压的监测,以极早防治青光眼等并发症。

Cataract surgery in patients with Behçet's disease

PURPOSE: To evaluate the outcomes and complications of cataract surgery in patients with Beh?et's disease. SETTING: Department of Ophthalmology, Hacettepe University School of Medicine, Ankara, Turkey. METHODS: Thirty-three eyes of 26 patients with Beh?et's disease that had extracapsular cataract surgery between January 1993 and July 1999 were analyzed retrospectively. The mean age of the patients was 38.9 years (range 20 to 54 years). The mean postoperative follow-up was 22.9 months (range 6 to 66 months). RESULTS: Extracapsular cataract extraction (ECCE) was performed in 22 eyes with and in 6 eyes without intraocular lens (IOL) implantation. Phacoemulsification with IOL implantation was performed in 5 eyes. Postoperatively, the visual acuity was better in 29 eyes (87.8%) and was 0.5 or better in 14 eyes (42.4%). Posterior segment complications of Beh?et's disease, mainly optic atrophy and macular alterations from preoperative inflammatory episodes, restricted final acuity. No significant difference was detected in postoperative inflammation among the types of surgery; that is, ECCE, ECCE with IOL implantation, and phacoemulsification with IOL implantation. A neodymium:YAG laser posterior capsulotomy was performed in 3 cases. CONCLUSIONS: In patients with Beh?et's disease, inflammation after extracapsular surgery was mild when surgery was performed after at least 3 months of no inflammatory signs. The results show that the outcomes of extracapsular cataract surgery mainly depend on the degree of preoperative posterior segment involvement.

Small-incision manual extracapsular cataract surgery in Ghana,West Africa

PURPOSE: To evaluate the results of small-incision manual extracapsular cataract extraction surgery (ECCE) in a district hospital in West Africa. SETTING: Margret Marquart Catholic Hospital, Ghana, West Africa. METHODS: This prospective study consisted of 200 eyes of 193 patients who had small-incision manual ECCE between January 1999 and May 2000. For comparison, the charts of 32 patients (32 eyes) operated on between July and December 1998 using a limbal incision (control group) were retrospectively analyzed. Outcome measures included intraoperative and postoperative complications, postoperative visual acuity, and refractive astigmatism. RESULTS: In the small-incision ECCE group, self-sealing wounds were achieved in 129 eyes (64.5%). Vitreous loss occurred in approximately 3% of eyes in both the small-incision and control groups. The final visual acuities were similar between the 2 groups, with more than 90% of eyes in both groups achieving a final best corrected visual acuity of at least 20/60. Eyes in the small-incision group had faster visual recovery (P <.001), a lower incidence of fibrinous iritis (P =.02), and were more likely to have round pupils (P <.001) than eyes in the control group. The main complication of small-incision surgery was moderate corneal edema, which persisted until at least the 1-week visit in 14 eyes (7%). At the most recent visit, 1 eye in the small-incision group (0.5%) had bullous keratopathy. CONCLUSION: In a district hospital in West Africa, small-incision manual ECCE surgery yielded faster visual rehabilitation and had a lower incidence of fibrinous iritis than standard ECCE surgery.     

The results of cataract extraction and intraocular lens implantation in patients with Behçet's disease

PURPOSE: To evaluate the results of extracapsular cataract extraction (ECCE) and intraocular lens (IOL) implantation in patients with Beh?et's disease. METHODS: Retrospective study was based on 19 uveitic eyes of 12 patients with Beh?et's disease who underwent classic ECCE with IOL implantation in 5 eyes and phacoemulsification with IOL implantation in 14 eyes between 1993-1999. RESULTS: In eyes with Beh?et's uveitis 0.5 or better postoperative visual acuity was found in 21% at the end of mean 34.2-4.6 (range 5 to 66) months follow-up. The most frequent postoperative complications were posterior capsule opacification in 9 (47%), posterior synechiae in 5 (26%), anterior synechiae in 3 (16%). Anterior and posterior synechiae in the phacoemulsification group were less than those in the ECCE group (respectively p<0.05 and p<0.01). CONCLUSIONS: In eyes with chronic Beh?et's uveitis, cataract extraction and IOL implantation by phacoemulsification had fewer postoperative complication than ECCE, but most of the patients had low visual acuity due to preoperatively existing optic atrophy and/or inflammatory degeneration or edema of macula.     

青光眼合并白内障分期手术与联合手术比较

目的 :比较青光眼白内障分期手术和联合手术对患者视力眼压的影响。方法 :对 2 3例 (2 3眼 )施行联合手术加后房型人工晶体植入术 ;对 18例 (2 1眼 )首先行小梁切除术 ,术后 8个月～ 12年后行囊外摘除加后房型人工晶体植入术。比较术后矫正视力 ,角膜散光 ,眼压和滤过泡 ,结果采用spss软件行统计分析。结果 :术后二者矫正视力和角膜散光差别无显著性 (P >0 0 5 ) ;眼压 ,滤过泡差别成显著性 (P <0 0 5 )。结论 :青白联合手术术后滤过泡形成相对较差 ,眼压控制欠稳定 ,故虽早期视力和分期手术无差别 ,但长期不稳定的眼压对视功能将产生一定的影响
