Summary
A dense intraocular membrane formed after combined phacoemulsification-trabeculectomy. This complication, potentially from pigment epithelium or deposition, was treated with medication and Nd:YAG laser.
Area of Science:
- Ophthalmology
- Surgical Complications
- Membrane Formation
Background:
- Combined phacoemulsification-trabeculectomy is a surgical procedure for managing cataracts and glaucoma.
- Postoperative membranes can occur, particularly after complex or combined ocular surgeries.
- Understanding the etiology and management of these membranes is crucial for patient outcomes.
Observation:
- A case of dense intraocular membrane formation following combined phacoemulsification-trabeculectomy is presented.
- The membrane's origin is hypothesized to be either a detached pigment epithelial fragment or significant pigment deposition on a pupillary membrane.
- Such postoperative membranes are noted to be more prevalent after combined surgical procedures.
Findings:
- The intraocular membrane was successfully managed using a multimodal approach.
- Treatment involved intensive topical dexamethasone and homatropine.
- Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser application was also utilized to expedite membrane resolution.
Implications:
- This case highlights a potential complication of combined phacoemulsification-trabeculectomy.
- It underscores the importance of recognizing and managing postoperative intraocular membranes.
- The reported treatment strategy offers a potential pathway for resolving such membranes, improving visual function.
