Pilot Trial of Transscleral Diode Laser Retinopexy in Retinal Detachment Surgery

Arch Ophthalmol. 1993;111(7):952-956. doi:10.1001/archopht.1993.01090070070022

Objective:  To evaluate the safety and efficacy of the transscleral diode laser for retinopexy in rhegmatogenous retinal detachments.

Design:  Ten consecutive patients with primary rhegmatogenous retinal detachments underwent scleral buckling surgery, using the transscleral diode laser for retinopexy. Patients were followed up for at least 6 months.

Study Participants:  Ten patients with primary rhegmatogenous retinal detachments were enrolled. Patients with chronic detachments, a retinal break greater than 90°, history of uveitis or infectious retinopathy, or proliferative vitreoretinopathy were excluded.

Main Outcome Measure:  Retinal reattachment. Secondary measures: visual acuity and complications, including choroidal, retinal, and vitreous hemorrhage, inflammation, and scleral damage.

Results:  By 6 months, nine of 10 retinas were successfully repaired following only one operation. The retina of the 10th patient redetached at 6½ weeks owing to proliferative vitreoretinopathy. Following a vitrectomy and retinal reattachment procedure, the retina of the 10th patient has remained attached for 1 year. No significant complications were encountered with the laser retinopexy, although small presumed breaks in Bruch's membrane occurred in three eyes and a moderate scleral thermal effect occurred in two. Visual results in the postoperative course were comparable to those achieved previously with cryotherapy.

Conclusion:  In this pilot series, transscleral diode laser retinopexy served as a safe and effective means of obtaining chorioretinal adhesion in retinal detachment surgery.
