Ocular decompression retinopathy after trabeculectomy with mitomycin-C for angle recession glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Research
• Retinal Diseases

Background:

• Post-traumatic angle recession glaucoma presents unique challenges in intraocular pressure (IOP) management.
• Trabeculectomy with mitomycin-C (MMC) is a standard surgical intervention for refractory glaucoma.
• Ocular decompression retinopathy (ODR) is a rare complication following glaucoma surgery.

Observation:

• A 45-year-old male with intractable glaucoma secondary to blunt trauma underwent successful trabeculectomy with MMC.
• Despite meticulous surgical technique and absence of hypotony, the patient developed ODR.
• This case prompted a review of existing ODR pathophysiology.

Findings:

• Existing literature primarily associates ODR with a significant postoperative IOP drop.
• A novel hypothesis suggests that a history of rapid IOP fluctuations or intermittent high IOP spikes may predispose patients to ODR.
• This factor has not been previously implicated in the pathophysiology of ODR.

Implications:

• This finding may necessitate a re-evaluation of patient selection and preoperative IOP management in glaucoma surgery.
• Understanding the role of IOP variability could lead to improved strategies for preventing ODR.
• Further research is warranted to validate the proposed link between IOP spikes and ODR development.
