Long-term follow-up of intermediate uveitis in children

PURPOSE: To analyze the clinical manifestations, remissions, and visual prognosis of intermediate uveitis in children, and to identify the risk factors for poor visual outcome. DESIGN: Retrospective cohort study. METHODS: Institutional study of 32 consecutive patients examined at a tertiary referral center with intermediate uveitis and the onset of ocular disease before the age of 16 years. Numerous variables were assessed, including age and gender distribution, laboratory data, the presence of systemic diseases, onset and course of ocular inflammation, clinical features and complications, therapeutic strategies and their outcomes, remission and final visual acuity, and characteristics associated with poor visual outcome. RESULTS: Bilateral involvement was observed in 94% of the patients. Remission was observed in seven out of 15 patients (47%) with completed follow-up of five years. For our 32 subjects, we found a mean time to remission of 6.4 years (SE 0.7, CI 5.1 to 7.7). Visual outcome was favorable as only three patients developed unilateral acuity of less than 0.1 after five-year follow-up, and no additional blind eyes manifested. No associated systemic diseases were established. Optic disk edema was the most frequent complication observed (71%). Cystoid macular edema (CME) was observed in 44% of the patients and was the most common cause of visual loss. CONCLUSIONS: Intermediate uveitis of childhood might exhibit a self-limiting course after several years. Visual loss was limited despite the high rate of severe ocular complications.     

Long-term follow-up of initial trabeculectomy with mitomycin C for primary open-angle glaucoma in Japanese patients

PURPOSE: To determine the long-term intraocular pressure (IOP) control and postoperative complications after initial trabeculectomy with use of mitomycin C (MMC) in patients with primary open-angle glaucoma (POAG). PATIENTS AND METHODS: A retrospective review was conducted of a consecutive series of 123 eyes (87 patients) with POAG who underwent initial trabeculectomy with MMC and had at least 4 years of follow-up. All patients underwent standard trabeculectomy with 0.04% MMC applied intraoperatively for 3 minutes. The long-term outcomes (IOP control and bleb leak, long-standing hypotony, bleb-related infections) were analyzed with the Kaplan-Meier life-table method on the basis of three definitions of successful IOP control (defined as IOP <18 mmHg (definition 1), IOP <16 mmHg (definition 2), and IOP decrease of by > or =30% and <21 mmHg (definition 3)). RESULTS: The mean follow-up time was 6.8+/-1.4 (mean+/-SD) years. The cumulative survival rates were 67.0+/-4.6%, 44.5+/-5.4%, and 74.1+/-4.2%, respectively, based on definitions 1, 2, and 3, 8 years postoperatively by life-table analysis. At 8 years, bleb leak occurred in 7.9+/-2.6% of eyes, long-standing hypotony in 8.3+/-2.5%, and bleb-related infections in 5.9+/-2.4%. CONCLUSION: Long-term outcome after initial trabeculectomy with MMC in Japanese POAG patients is comparable with that reported in other populations and with that after trabeculectomy with 5-fluorouracil.     

Long-term follow-up of initially successful trabeculectomy with 5-fluorouracil injections

PURPOSE: To study the long-term results (1-14 years) of trabeculectomies with 5-fluorouracil injections that were successful at 1 year. DESIGN: A retrospective noncomparative case series. INTERVENTION/PARTICIPANTS: We identified 87 patients (87 eyes) who had trabeculectomies with 5-fluorouracil injections from 1984 to 1989 that were successful at 1 year and had a follow-up range of 1.0 to 14.7 years (mean, 8.1, standard deviation of 4.4 years). All patients had previously failed glaucoma surgery (66.7%), cataract surgery (47.1%), or other diagnoses making them at high risk for failure. MAIN OUTCOME MEASURES: Successful control of intraocular pressure (IOP) was defined as IOP less than 21 mmHg or a reduction of 33% if preoperative pressure was less than 21 mmHg. Statistical analysis was performed using Kaplan-Meier life table analysis. RESULTS: If an eye is considered successful by IOP at 1 year, the probability of successful control is 61% at 5 years, 44% at 10 years, and 41% at 14 years. CONCLUSIONS: Despite successful IOP control at 1 year, trabeculectomies with 5-fluorouracil injections show a continual loss of IOP control over time.     

Long-term reduction of laser flare values after trabeculectomy but not after cyclodestructive procedures in uveitis patients

The aim of this study was to examine long-term changes of laser flare (LF) after trabeculectomy (TE) and transscleral diode cyclophotocoagulation (TDCPC) in patients with uveitic secondary glaucoma. Retrospective, single-center analysis. Overall, 40 TE (mean follow-up 21.1 months) and 68 TDCPC (mean follow-up 21.8 months, P = 0.38) procedures were performed. The intraocular pressure (IOP) level was consistently lower in the TE group at the preoperative visit and at each follow-up visit, while IOP reduction was similar in both groups (P = 0.91). LF decreased from 59.4 photons/ms at baseline to 41.9 photons/ms in the TE group (P = 0.017) and remained unchanged in the TDCPC group (71.2 vs. 70.7 photons/ms, P = 0.84). No significant increase in the number of complications could be observed at the end of the postoperative follow-up, while best-corrected visual acuity drop and cataract formation was higher in the TE group. TE significantly reduced postoperative LF values. Higher LF values did not increase the development of new complications in this study, but an increased occurrence of cataract formation was seen in the TE group.     

Long-term follow-up of trabeculectomy with intraoperative 5-fluorouracil for uveitis-related glaucoma

PURPOSE: To determine the effect of intraoperative application of 5-fluorouracil (5-FU) on the long-term outcome of trabeculectomy in uveitis-related glaucoma. DESIGN: An open, prospective, noncomparative case study to evaluate the use of intraoperative application for 5 minutes of 25 mg/ml 5-FU in primary trabeculectomy for uveitis-related glaucoma. PARTICIPANTS: Fifty eyes of 43 consecutive patients were enrolled in the study. METHODS: Data were recorded prospectively on specifically designed forms at visits every 3 months after surgery. MAIN OUTCOME MEASURES: The intraocular pressure, need for additional medication, and the need for repeat surgery were the criteria that determined the outcome of surgery. RESULTS: No significant intraoperative, postoperative, or late complications of 5-FU administration were noted. Successful filtration was achieved in 82% of eyes at 1 and 2 years after surgery. The success rate was 67% at 5 years. Failure was significantly more common and occurred earlier in patients of black ethnic origin. No deleterious effect on control of uveitis in relation to surgical intervention was observed. CONCLUSIONS: Intraoperative application of 5-FU appears to be a long-term, safe, and effective adjunct to trabeculectomy in uveitis-related glaucoma.     

Long-term follow-up of tacrolimus treatment in immune posterior uveitis

PURPOSE: To study the efficacy of tacrolimus in immune posterior uveitis. METHODS: Twenty-one eyes of 11 patients with immune posterior uveitis under tacrolimus treatment were prospectively followed for 1 to 5 years. Tacrolimus dosage was adjusted to maintain blood levels in the range of 7 to 10 ng/mL. Systemic and ophthalmic evaluations were performed at baseline and during follow-up. RESULTS: After a mean follow-up of 45 months, no treatment other than tacrolimus was necessary to control the inflammation in 6 cases (54.5%). The number of annual recurrences decreased from 3.2 to 1.29 during tacrolimus treatment (p=0.021). In four patients, tacrolimus was suspended after a treatment period of 27+/-3.5 months and a follow-up period of 12 months free of uveitis relapses. All four were free from relapses following tacrolimus withdrawal. Visual acuity remained unchanged in 16/21 (76%) eyes, deteriorated in 4/21 (19%), and improved in 1/21 (5%). Renal function transiently deteriorated in four patients from basal serum creatinine levels of 0.84, 1.1, 0.88, and 0.78 mg/dL to maximum levels of 1.33, 2.48, 1.38, and 1.39 mg/dL, respectively. This deterioration was directly related with elevated tacrolimus serum levels, returning to normal when doses were reduced. During the overall controlled evolution period, a slight increase of serum creatinine from a basal value of 0.89+/-0.2 mg/dL to a final of 1+/-0.19 mg/dL was detected, which was not statistically significant. All secondary effects were mild, transient, and did not require interruption of long-term treatment to be controlled. CONCLUSIONS: Tacrolimus was well tolerated and useful in controlling posterior immune uveitis. Tacrolimus could be considered a real alternative to cyclosporine, and not only in cases of cyclosporine resistance or toxicity.     

Long-term follow-up of initial 5-fluorouracil trabeculectomy in primary open-angle glaucoma in Japanese patients.

PURPOSE: To evaluate the long-term efficacy and safety of initial trabeculectomy with subconjunctival 5-fluorouracil in Japanese patients with primary open-angle glaucoma. SUBJECTS AND METHODS: Clinical records of 117 eyes from 117 patients with records of up to 14 years were retrospectively analyzed using the appropriate statistical methods. RESULTS: The mean follow-up period was 6.2 +/- 3.6 years. Criteria for successful intraocular pressure control and success probability by Kaplan-Meier method at 12 years were intraocular pressure < 21 mm Hg without medication plus a 30% or more reduction in intraocular pressure, 50.4 +/- 5.2% (SE) 38.2 +/- 5.3%; and intraocular pressure < 16 mm Hg without medication plus a 30% or more reduction in intraocular pressure, 45.9 +/- 5.1% (36.5 +/- 5.2%). Cox multiple regression analysis showed that a younger age was associated with a higher success probability (P <0.01). Eyes with lower postoperative intraocular pressure tended to show more positive value of the MD slope (P = 0.0669), whereas 7% of successfully treated eyes showed a negative postoperative MD slope (P < 0.1). The probabilities for developing bleb leaks and bleb-related infections in eyes with a functioning bleb were 28.9 +/- 12.5% and 13.0 +/- 10.4% at 12 years. CONCLUSION: Trabeculectomy with 5-fluorouracil as an initial surgery in Japanese patients with primary open-angle glaucoma was effective for long-term control of glaucoma. However, the probability of late-onset bleb-related complications was not low in eyes with a functioning bleb, stressing the importance of constant care regarding bleb status.     

The use of antimetabolites with trabeculectomy: a critical appraisal

PURPOSE: To examine why most ophthalmologists routinely use mitomycin C or 5-fluorouracil (antimetabolites) in association with filtering surgery for glaucoma. METHODS: Critical analysis of seven medical, social and economic trends. RESULTS: The rapid acceptance of the adjunctive use of antimetabolites at the time of filtration surgery may be explained by reasons other than anticipated increase in the "success" of glaucoma surgery. CONCLUSION: The use of antimetabolites in conjuction with filtering glaucoma surgery may be at least partially a consequence of changing medical-social-economic factors, rather than solely a desire on the part of physicians to improve the "success" of glaucoma surgery. This may indicate a need to reevaluate the proper place of antimetabolites in association with filtration surgery.     

Long-term outcomes of small-incision cataract surgery in patients with uveitis

Purpose:To evaluate the long-term outcomes of manual small-incision cataract surgery (MSICS) in eyes with uveitis.Methods:Patients who underwent MSICS for uveitic cataract from 2009 to 2019 were retrospectively evaluated. Visually significant cataract and presence of less than five cells per high-power field in the anterior chamber for a minimum of 3 months were the prerequisites for surgery. Patients with follow-up less than 9 months were excluded.Results:After exclusion, 283 eyes of 264 patients were evaluated. The mean age of patients was 44.3 ± 11.3 years. The mean follow-up duration was 22 ± 11.5 months. The mean surgical time was 11.2 ± 3.2 min. One hundred and seventy-two eyes (60.8%) had anterior uveitis, 78 (27.5%) had posterior uveitis, and 33 (11.7%) had panuveitis. At the final follow-up, 253 eyes (88.4%) had corrected distance visual acuity (CDVA) better than 0.6 log of minimum angle of resolution (LogMAR) unit. The final endothelial cell counts were significantly (analysis of variance [ANOVA], P = 0.001) lower in eyes with human leukocyte antigen (HLA)-B27–associated uveitis and in eyes with idiopathic anterior uveitis. Patients on systemic corticosteroids had significantly better (P = 0.031) final visual acuity than those without preoperative corticosteroids. Recurrent uveitis (43.8%), Posterior capsule opacification (PCO) (19.4%), glaucoma (8.5%), cystoid macular edema (CME; 13.5%), and Epiretinal membrane (ERM) (5.6%) were the frequent complications. A significantly worse (ANOVA, P = 0.001) visual prognosis was seen in patients with Vogt–Koyanagi–Harada disease (VKH), sarcoidosis, acute posterior multifocal placoid pigment epitheliopathy (APMPPE), and serpiginous choroiditis.Conclusion:MSICS is safe in most cataracts due to uveitis and results in improvement in CDVA at 9 months. Posterior capsule opacification, macular edema, persistent uveitis, etiology of uveitis, and use of preoperative steroids significantly influenced the visual outcome.     

Long-term follow-up of primary glaucoma surgery with Ahmed glaucoma valve implant versus trabeculectomy

PURPOSE: To compare the long-term results of trabeculectomy and Ahmed glaucoma valve implant in the initial surgical management of primary open- and closed-angle glaucoma. DESIGN: Randomized controlled clinical trial. METHODS: One eye each of consecutive patients with primary glaucoma and without prior intraocular surgery was randomized to receive either trabeculectomy or the Ahmed implant.Large university-affiliated eye hospital in Columbo, Sri Lanka. RESULTS: Of 123 patients, 64 were randomized to trabeculectomy and 59 to the Ahmed implant. With a mean follow-up of 31 months, the trabeculectomy group had statistically lower intraocular pressures (IOP) during the first postoperative year. After the first year, the IOPs were comparable. No statistically significant differences between groups were noted for postoperative visual acuity, visual field, anterior chamber depth, and short-term or long-term complications. Adjunctive medication requirement was comparable for both groups. The cumulative probabilities of success (IOP <21 mm Hg and at least 15% reduction in IOP from preoperative levels) at the final follow-up period (months, 41-52) were 68.1% for trabeculectomy and 69.8% for Ahmed implant (P =.86). CONCLUSIONS: Lower IOPs were noted for the trabeculectomy group during the first year. With longer follow-up, the IOPs and the cumulative probabilities of success were comparable between the two groups.     

Long-term results of cataract surgery in patients with anterior uveitis

Purpose

This study was aimed to assess the long-term results of phacoemulsification and posterior chamber intraocular lens implantation in patients with anterior uveitis.

Methods

Patients with complicated cataract secondary to anterior uveitis who underwent phacoemulsification and posterior chamber intraocular lens implantation were included in this study. Long-term results and all complications were evaluated throughout the postoperative 4 years.

Results

A total of 55 eyes of 48 patients were identified in this study. Cases with anterior uveitis were categorised into four aetiologic groups. Of the 55 eyes, 22 (19 patients) had idiopathic anterior uveitis, 10 (9 patients) had viral anterior uveitis, 10 (9 patients) had Fuchs’ anterior uveitis and 13 (11 patients) had anterior uveitis associated with collagen vascular diseases. Preoperative macular oedema was more frequent (63.6%) in the idiopathic group than in the other groups (p < 0.001). The success rates of the best corrected visual acuity of 20/40 or better ranged from 80.0 to 100.0% in the groups. While postoperative increased intraocular pressure rate was statistically significantly higher in the Fuchs’ group (p = 0.047), there was no statistically significant difference in other complication rates between the groups.

Conclusions

The long-term outcomes of phacoemulsification with intraocular lens implantation in patients with uveitic cataract were satisfactory with excellent visual acuity and relatively low complication rates.

     

Treatment of uveitis with immunosuppressives: antimetabolites and alkylating agents

Oral corticosteroids remain the main therapeutical choice in patients with uveitis not responding to topical treatment, however their chronic use can be very toxic, especially for bones (osteoporosis or growth retardation). Immunosuppresive agents are used as corticosteroid sparing agents and/or as agents able to control refractory uveitis in sight threatening uveitis. Cyclosporin A is very efficacious but is nephrotoxic, in particular in old people. Methotrexate is well tolerated in young people, is not carcinogenic but not very active. Azathioprine is well tolerated but it's carcinogenic effect and its delayed action are helpful in chronic uveitis of old women. Cyclophosphamide and intravenous steroids are helpful for emergencies. Chlorambucil is toxic and carcinogenic but might lead to an increased rate of remission and might be useful as a short treatment. In any case, a careful and regular follow-up in collaboration with a competent internist is mandatory.     

Success criteria and success rates in trabeculectomy with and without intraoperative antimetabolites using intensified postoperative care (IPC)

Purpose: To define the success rate of trabeculectomy for surgical treatment of glaucoma under intensified postoperative care (IPC) conditions in cases of severe visual field damage or progression of visual field loss. Methods: In a retrospective study, we evaluated the outcome of trabeculectomy in 99 eyes of 99 patients from October 1995 to June 1997. In 23 eyes, antimetabolites were used intraoperatively. Regarding intraocular pressure (IOP), success was defined as lowering the preoperative, maximally treated IOP by more than 20% in addition to a postoperative IOP level lower than 21 mmHg without using further glaucoma medication. Success rate was defined by stabilisation of visual acuity and visual field in addition to IOP reduction. Results: The postoperative IOP was 14.7 mmHg (±3.4 mmHg) following standard trabeculectomy (preoperative IOP 24.3±6.7 mmHg) and 15.8 mmHg (±4.9 mmHg) following trabeculec-tomy with intraoperative anti- metabolites (preoperative IOP 27.0±9.5 mmHg). The success rate concerning the IOP was 83% in standard trabeculectomy and 74% following trabeculectomy with intraoperative antimetabolites. The visual acuity showed stabilisation in 93% of cases following standard trabeculectomy and in 100% following trabeculectomy with intraoperative antimetabolites. The visual field showed stabilisation according to the Aulhorn criteria in 95% and 94% of cases following standard trabeculectomy and trabeculectomy with intraoperative antimetabolites, respectively. The total success rate using all criteria together was 76% following standard trabeculectomy and 74% following trabeculectomy with intraoperative antimetabolites. Conclusion: The overall outcome after trabeculectomy is good with appropriate follow-up and timely decisions for after- treatment to ensure good development of the filtering bleb.

Long-term follow-up of visual field progression after trabeculectomy in progressive normal-tension glaucoma

OBJECTIVE: To evaluate the long-term effects of trabeculectomy on the progression of visual field damage in patients with progressive normal-tension glaucoma (NTG). DESIGN: Retrospective, noncomparative, interventional case series. PARTICIPANTS: Twenty-three patients with NTG who had significant progression of visual field damage preoperatively and underwent trabeculectomy using antimetabolites. METHODS: Visual field testing using the Humphrey Visual Field Analyzer was periodically performed before and for at least 5 years after surgery (mean, 6 years). The time course of the mean deviation (MD) and mean of total deviations (TD(mean)) in four separate subfields, superior and inferior cecocentral and superior and inferior arcuate fields, were analyzed using a linear mixed effects model. MAIN OUTCOME MEASURES: Intraocular pressure (IOP), preoperative and postoperative regression coefficients of the time course of MD or TD(mean) in the four subfields, corresponding to the rate of progression of visual field damage. RESULTS: IOP significantly decreased from 16.2 +/- 1.8 mmHg preoperatively to approximately 11 mmHg during the postoperative follow-up period (P < 0.001). The preoperative regression coefficient of MD change was significantly negative (-1.05 [95% confidence interval, -1.28 to -0.82] dB/year, P < 0.001). After surgery, it increased significantly to -0.44 (95% confidence interval, -0.64 to -0.24) dB/year (P < 0.001), but the postoperative value was still significantly negative (P < 0.001). In the superior cecocentral, superior and inferior arcuate fields, preoperative regression coefficients of TD(mean) change were significantly negative (P < 0.001) and significantly increased after surgery (P < 0.01). In the inferior cecocentral field, the preoperative regression coefficient was not significantly different from 0 (P = 0.72) and did not change significantly after surgery (P = 0.15). CONCLUSIONS: Trabeculectomy was statistically associated with slowing further progression of visual field damage in patients with progressive NTG. The progression, however, did not completely stop over the 6-year postoperative follow-up period.     

Recurrent anterior uveitis after trabeculectomy with mitomycin C

Objective: To report 4 cases of recurrent anterior uveitis occurring 1–11 months after trabeculectomy with mitomycin C.Design: Observational case series.Participants: Four patients in whom recurrent uveitis developed after trabeculectomy with mitomycin C, followed at Maisonneuve-Rosemont Hospital in Montreal, Quebec. Methods: Retrospective review of the medical records.Results: One to 11 months after trabeculectomy with mitomycin C, noninfectious, recurrent anterior uveitis developed in 4 patients with no prior history of uveitis. Topical and intravitreal corticosteroids were effective in reducing acute inflammation, yet 2 patients went on to have chronic anterior uveitis.Conclusions: Recurrent anterior uveitis presenting later than 3 weeks postoperatively may be associated with trabeculectomy with mitomycin C. It should be included in the differential diagnosis of a nonresolving blebitis.     

Long-term follow-up of patients with serpinginous choroiditis

PURPOSE: To evaluate the long-term clinical course of serpiginous choroiditis-a recurrent inflammatory disease that causes progressive visual loss-and to determine the efficacy of immunosuppressive therapy. METHODS: A retrospective study of patients who met inclusion criteria for serpiginous choroiditis at The University of Iowa Hospitals and Clinics was performed. Information collected included duration of follow-up, number of recurrences of inflammation, visual acuities, and development of choroidal neovascularization. The number of recurrences of inflammation in patients treated with immunosuppressive agents was compared with that in patients treated only with corticosteroids or observation. RESULTS: Seventeen patients were identified who had a mean age at presentation of 39.6 years. The mean duration of follow-up was 149.2 months, with 13 patients who were followed up for >60 months. Twelve eyes either presented with or developed macular choroidal neovascularization during follow-up. Thirteen of the patients were followed up for >12 months. Of these 13 patients, 6 received treatment with immunosuppressive agents along with corticosteroids. Four of the six patients developed no further inflammatory recurrence. Seven of the 13 patients were treated with corticosteroids or observation. All of these patients developed recurrences (P = 0.021, Fisher exact test). CONCLUSIONS: Immunosuppressive agents appear to reduce the rate of recurrent disease in serpiginous choroiditis compared with corticosteroids.
