Non-penetrating deep sclerectomy for glaucoma associated with Sturge-Weber syndrome

PURPOSE: To report the results of non-penetrating deep sclerectomy (NPDS) in the treatment of glaucoma associated with Sturge-Weber syndrome (SWS). METHODS: We carried out a retrospective case series analysis of patients who underwent NPDS for glaucoma associated with SWS between 1998 and 2003. The control of glaucoma after NPDS, the results of surgery on intraocular pressure, the need for additional medical treatment and surgical complications were studied. RESULTS: Twelve eyes of nine patients, aged 11 days to 24 years, underwent filtering surgery: nine NPDS procedures were performed and three surgical procedures had to be converted to trabeculectomy because NPDS was not technically achievable. The mean follow-up after surgery was 26.3 months (range 6-48 months). Two trabeculectomies were complicated by choroidal effusion, which resolved in both cases. Good control of glaucoma was obtained during follow-up. CONCLUSIONS: Non-penetrating deep sclerectomy is transiently efficient in the treatment of SWS-associated glaucoma. Further studies of NPDS for the treatment of glaucoma associated with SWS are warranted.

Non-penetrating deep sclerectomy and collagen implant surgery in glaucoma patients with advanced field loss

Purpose: The aim of the study was to determine the medium term intraocular pressure (IOP) lowering effects and the potential complications of non-penetrating deep sclerectomy and collagen implant (DSCI) surgery in glaucoma patients. Patients and methods: 54 eyes of 52 patients with medically uncontrolled open angle glaucoma with advanced field loss underwent DSCI under topical anaesthesia. Follow-up period was 24 months. Results: The mean preoperative IOP was 24.7 ± 6.2 mmHg and decreased to 15.1 ± 4.0 mmHg at 24 months (p = 0.0068). During the follow- up period, 36 of 54 eyes (66%) received no topical antiglaucomatous medications. In 18 eyes, monotherapy with topical beta blockers (Betaxolol HCl) was added to the regimen. At last visit , only two patients (3.8%) had IOP greater than 18 mmHg. We did not detect any additional optic disc changes, visual field or visual acuity defects postoperatively. Detailed slit-lampexamination revealed no anterior segment complications regarding the probablecomplications of trabeculectomy. None of the patients developed surgery relatedcataract. As a complication, we diagnosed one case of self-limited, shallow choroidal detachment. Conclusion: DSCI appears to provide considerable medium term IOP decrease with few postoperative complications without deteriorating visual acuity. Owing to our medium term results, we believe that DSCI could be a valuable alternative to trabeculectomy especially in cases of advanced medically uncontrolled open angle glaucoma.     

Deep sclerectomy in patients with capsular glaucoma

PURPOSE: To compare the results of deep sclerectomy in capsular glaucoma (CG) with those in primary open-angle glaucoma (POAG). METHODS: This consecutive, prospective study comprised 24 CG patients (28 eyes) and 25 POAG patients (29 eyes) who underwent deep sclerectomy. Two different implants were used: either an absorbable collagen implant (Aqua-Flow) or a non-absorbable hydrophilic acrylic implant (T-Flux). The number of glaucoma medications, intraocular pressure (IOP) and complications were compared postoperatively. The definition of complete success was IOP below 19 mmHg without therapy. RESULTS: After a mean follow-up of 19.9 +/- 10.9 months (range 6-36 months) in the CG group and 16.2 +/- 10.0 months (range 6-36 months) in the POAG group, complete success was seen in 60.7% and in 37.9% of eyes, respectively (p=0.085). After adjustments for disparities in baseline characteristics, survival analysis demonstrated that success rates were better over time in CG eyes than in POAG eyes (p=0.038). At all time-points, except at 24 months, the IOP was lower in the CG group than in the POAG group. This difference was statistically significant at 1 week (p=0.050) and 3 months (p=0.006). At 18 months, the mean decrease in number of medications was 77.3% in the CG group and 65.9% in the POAG group (not statistically significant). Levelled hyphema occurred more frequently in CG eyes (35.7%) than in POAG eyes (13.8%). CONCLUSION: Capsular glaucoma patients had significantly higher success rates over time than POAG patients following deep sclerectomy with implant.

Comparison of deep sclerectomy with implant and combined glaucoma surgery

To evaluate the efficacy of combined glaucoma surgery, 42 glaucomatous patients were randomly divided into two groups: deep sclerectomy with implant (DS) alone was performed in 21 patients, and combined deep sclerectomy and phacoemulsification (PDS) was performed in the other 21 patients. Follow-up was carried out at regular intervals for 12 months. A comparative study on intraocular pressure (IOP) was designed. Although further study is needed, PDS appears to have better postoperative long-term results in IOP control than DS alone.     

Longterm follow-up after deep sclerectomy in patients with pseudoexfoliative glaucoma

PURPOSE: To compare the longterm results in pseudoexfoliative glaucoma and primary open-angle glaucoma (POAG) following deep sclerectomy with implant. METHODS: A total of 28 pseudoexfoliative glaucoma eyes and 27 POAG eyes were consecutively included in the study. Intraocular pressure (IOP) and number of glaucoma medications were compared before surgery and at every postoperative visit. Most patients included had very advanced glaucoma and were using multiple therapies (mean 3.3 and 3.6 in the pseudoexfoliative glaucoma and POAG groups, respectively) and the duration of the disease was more than 8 years in both groups. The definition of complete success was the achievement of IOP < 19 mmHg without therapy. RESULTS: After a mean follow-up time of 45 months in the pseudoexfoliative glaucoma group and 43 months in the POAG group, 50.0% of the pseudoexfoliative glaucoma group were considered to represent complete success compared with 33.3% of the POAG group (NS). In survival analyses controlling for covariates, it was found that patients with pseudoexfoliative glaucoma had a higher rate of success over time than POAG patients (p = 0.014). Furthermore, the duration of glaucoma prior to surgery had a negative influence on the success rate (p = 0.034). Four years after surgery, the mean IOP was 15.5 +/- 5.3 mmHg in the pseudoexfoliative glaucoma group and 13.6 +/- 3.5 mmHg in the POAG group (NS). The mean number of medications used by each group at that time was 1.7 +/- 1.5 and 1.2 +/- 1.1, respectively (NS). CONCLUSION: The present study suggests that deep sclerectomy is a safe procedure in pseudoexfoliative glaucoma. Half of the patients were regulated without therapy after 45 months.

Deep sclerectomy in pediatric glaucoma filtering surgery

Purpose

To study the additive value of deep sclerectomy to the procedure of combined trabeculotomy—trabeculectomy with mitomycin C (CTTM) for the treatment of primary congenital glaucoma.

Study design

This study is a prospective, randomized case series.

Patients and methods

The study was conducted on 20 eyes of 20 children with primary congenital glaucoma presenting to the Department of Ophthalmology of the Alexandria Main University Hospital. Preoperative examination under anesthesia was followed by surgical intervention. Postoperative examinations were conducted immediately after surgery and at 1, 2, 3, 6, 9, and 12 months. Intraoperative and postoperative complications, as well as operative time, were recorded.

Results

The mean (±SD, range) age of the study patients in the CTTM group and in the combined trabeculotomy–trabeculectomy with mitomycin C with deep sclerectomy (CTTM-DS) group was 4.7 (±2.0, 2–8) and 7.0 (±3.8, 3–13) months, respectively. The mean (±SD, range) preoperative intraocular pressure (IOP) in the CTTM and CTTM-DS groups was 16.7 (4.3, 10–26) and 16.4 (8.4, 8–36), respectively, and these dropped at 12 months of follow-up to 4.9 (2.0, 2–8) and 5.6 (3.3, 2–10), respectively. The mean (±SD, range) of the duration of the operation in the CTTM and the CTTM-DS was 57 (±8, 50–71) min and 53 (±7, 42–64) min, respectively (P=0.428). Two eyes (20%) in the CTTM-DS group developed hypotony disc edema at the first 2 months and resolved spontaneously thereafter. No other complications were noted in either of the groups.

Conclusion

The addition of deep sclerectomy to the procedure of CTTM in pediatric glaucoma surgery facilitates the finding of Schlemm''s canal, shortens the duration of surgery, and is not associated with any additional complications. Hence, the author recommends the addition of deep sclerectomy to CTTM surgery for primary congenital glaucoma.
