[Practical value of preventive posterior sclerectomy in trabeculectomy]

Area of Science:

• Ophthalmology
• Surgical Innovation

Context:

• Antiglaucoma surgery, specifically trabeculectomy, carries a risk of ciliochoroid detachment.
• Ciliochoroid detachment can lead to complications and compromise surgical success.

Purpose:

• To evaluate the efficacy of prophylactic posterior sclerectomy in preventing ciliochoroid detachment during trabeculectomy.
• To determine if the location of prophylactic posterior sclerectomy impacts its effectiveness.

Summary:

• A study analyzed 293 patients (303 eyes) undergoing trabeculectomy, with 51.8% receiving prophylactic posterior sclerectomy.
• Prophylactic posterior sclerectomy reduced ciliochoroid detachment incidence by 2.3 times (from 28.1% to 12.1%).
• The location of the sclerectomy (upper or lower segment) did not significantly affect outcomes.

Impact:

• Prophylactic posterior sclerectomy is an effective method for preventing ciliochoroid detachment in glaucoma surgery.
• This technique can improve the safety profile of antiglaucoma fistulization procedures.
• The findings support the routine adoption of prophylactic posterior sclerectomy to minimize postoperative complications.
