Abstract
Purpose: To report the outcomes of trabeculectomy in eyes with glaucoma in microspherophakia.
Materials and Methods: In a retrospective non-comparative case series, we analyzed 29 eyes of 18 patients
with glaucoma in microspherophakia, who underwent primary trabeculectomy between 1998 and 2012.
Success was defi ned as complete if the intraocular pressure (IOP) was ≤21 and >5 mm Hg without
any antiglaucoma medication and qualifi ed if IOP ≤21 and >5 mm Hg with or without antiglaucoma
medications. Eyes not falling into qualifi ed success criteria were labeled as failure. Results: The median age
at the time of trabeculectomy was 23 years (inter quartile range: 12, 28). The mean IOP reduced from 31.1
± 8.6 mm Hg to 14.6 ± 4.4 mm Hg after trabeculectomy over a median follow up of 77 months (P < 0.001).
The probability of complete success was 96% (95% CI: 77-99%) at one year, 88% (95% CI: 67-96%) at 2
years, which was maintained till 7 years and decreased to 79% (95% CI: 50-92%) at 8 years. The probability
of qualifi ed success was 100% till 7 years and decreased to 90% (95% CI: 47-98%) at 8 years. The median
number of postoperative medications reduced from 2 to 0 postoperatively (P < 0.001). Five eyes (21%)
developed post-operative shallow anterior chamber (AC) requiring anterior chamber reformation, with 2
of these eyes needing lensectomy for resolution of this complication. Conclusion: Primary trabeculectomy
had good success rate in glaucoma associated with microspherophakia. Post-operative shallow AC was a
frequent complication needing additional intervention.
