Sequential Serous Choroidal Detachment in Subjects Undergoing Bilateral Trabeculectomy.

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Surgical Complications

Background:

• Bilateral trabeculectomy (BT) is a common glaucoma surgery.
• Serous choroidal detachment (SCD) is a potential complication following ocular surgery.
• Understanding SCD incidence and impact in bilateral procedures is crucial for patient outcomes.

Purpose of the Study:

• To determine the incidence of serous choroidal detachment (SCD) in the second eye after bilateral trabeculectomy (BT).
• To evaluate the effect of SCD on the clinical outcomes and success rates of trabeculectomy in the second operated eye.

Main Methods:

• Retrospective case-control study of 45 patients (90 eyes) who underwent bilateral trabeculectomy.
• Surgical success defined by IOP between 5-21 mmHg, no further surgery, and visual acuity of at least light perception.
• Data collected included patient demographics, glaucoma type, comorbidities, IOP, and complications.

Main Results:

• The five-year success rate for BT was 61.0% in the first eye and 67.6% in the second eye.
• Serous choroidal detachment (SCD) occurred in 28.9% of eyes.
• Patients with SCD in the first eye had a significantly higher incidence of SCD in the second eye (76.9%, P $$ 0.001).
• Five-year survival probability was lower in eyes with SCD (35.0%) compared to those without (71.7%) in the first operated eye.

Conclusions:

• Occurrence of SCD in the first eye may predict its development in the second eye during bilateral trabeculectomy.
• The surgical success rate of the second operated eye in bilateral trabeculectomy is comparable to the first operated eye, even with SCD.
