Summary
Mitomycin intraoperative application during trabeculectomy improved intraocular pressure in 65.6% of high-risk glaucoma patients. Higher mitomycin concentrations increased efficacy but also complications, including hypotony.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Pharmacological Adjuncts
Context:
- Trabeculectomy is a primary surgical treatment for glaucoma.
- High-risk glaucoma patients often have suboptimal surgical outcomes.
- Intraoperative pharmacological agents can enhance surgical efficacy.
Purpose:
- To evaluate the efficacy of intraoperative mitomycin application in trabeculectomy for high-risk glaucoma.
- To compare outcomes using mitomycin concentrations of 0.2 mg/ml and 0.5 mg/ml.
- To assess complication rates associated with different mitomycin concentrations.
Summary:
- This study involved 32 eyes with secondary glaucoma (neovascular, aphakic/pseudophakic, post-trabeculectomy failure) receiving intraoperative mitomycin during trabeculectomy.
- Intraocular pressure normalization was achieved in 65.6% of cases (21 eyes) over a 1.5-year follow-up.
- Higher mitomycin concentrations (0.5 mg/ml) showed a trend towards more frequent pressure normalization but also increased complications, notably long-lasting hypotony.
Impact:
- Mitomycin as an intraoperative adjunct can improve trabeculectomy success rates in challenging glaucoma cases.
- Dosage optimization is crucial to balance efficacy and safety, minimizing risks like hypotony.
- Findings inform clinical decisions regarding mitomycin use in specific high-risk glaucoma populations.
