Risk factors for suprachoroidal hemorrhage associated with glaucoma surgery in children: a case-control study

Area of Science:

• Ophthalmology
• Pediatric Surgery
• Glaucoma Research

Background:

• Suprachoroidal hemorrhage (SCH) is a rare but serious complication following ocular surgery.
• Identifying risk factors for SCH in pediatric glaucoma surgery is crucial for patient safety.

Purpose of the Study:

• To investigate potential risk factors associated with suprachoroidal hemorrhage (SCH) in pediatric patients undergoing glaucoma surgery.
• To analyze the incidence and characteristics of SCH in a tertiary eye center cohort.

Main Methods:

• Retrospective review of 326 pediatric glaucoma surgery cases between January 2014 and September 2017.
• Comparison of 17 SCH cases with 309 control cases, documenting patient demographics, glaucoma type, and surgical details.
• Analysis included age, sex, intraocular pressure, axial length, pachymetry, lens status, and surgical procedures.

Main Results:

• SCH occurred predominantly in the early postoperative period, with only one intraoperative event.
• Primary congenital glaucoma (PCG) was the most common diagnosis in both SCH and control groups.
• Aphakia and combined glaucoma surgeries were identified as potential risk factors in univariate analysis.

Conclusions:

• Combined glaucoma surgeries and aphakia were associated with an increased risk of SCH in the studied pediatric population.
• These factors did not achieve statistical significance in the multivariable analysis, warranting further investigation.
