Trans-Scleral Diode Laser Retinopexy in Rhegmatogenous Retinal Detachment

Purpose: To evaluate the results of trans-scleral diode laser retinopexy for induction of chorioretinal reaction in scleral buckling surgery. Methods: This before-after clinical trial was performed on 69 eyes of 66 patients with rhegmatogenous retinal detachment eligible for scleral buckling. Results: The retina was reattached with scleral buckling in 64 eyes (92.8%). In 4 eyes, the scleral buckling was performed twice (modified). In 5 eyes, significant PVR developed post-operatively (7.2%), two of which had pre-operative PVR grade B. In two eyes, retinal photocoagulation was performed through silicon implants and sclera. Best corrected visual acuity (Log MAR) was 1.22±1.5 preoperatively and 0.74±1.75 postoperatively (P<0.02). In 95% of the eyes with reattached retina (61 eyes), visual acuity improved or remained stable. In 12 eyes, rupture of Bruchʹs membrane associated with retinal break formation happended which did not affect retinal reattachment. No other complications were seen which could be ascribed to diode retinopexy. Conclusion: Trans-scleral diode laser photocoagulation for induction of chorioretinal reaction in scleral buckling is a safe and effective procedure. The ability to perform retinopexy through episcleral silicon implants is a definite advantage of this method over cryopexy.
