Prophylactic argon laser coagulation for rhegmatogenous retinal detachment in AIDS patients with cytomegalovirus retinitis

· Background: The incidence of cytomegalovirus (CMV) retinitis in patients with acquired immunodeficiency syndrome (AIDS) reaches 20–45%. Despite aggressive medical treatment, rhegmatogenous retinal detachments develop in up to 30% of the affected eyes. Surgical repair is often difficult due to multiple, large and hardly visible retinal holes with vitreal traction. Pars plana vitrectomy with instillation of silicone oil is the procedure of choice, giving limited functional results with anatomical reattachment. · Methods: We performed prophylactic laser coagulation in AIDS patients with medically treated CMV retinitis to prevent a progressive retinal detachment. Twenty-two quiescent CMV lesions in 22 eyes of 20 patients were treated with argon green laser coagulation. Each CMV lesion was completely surrounded with a double or triple row of laser spots (500–600 μm; 0.2 s; gray-white lesions). · Results: The duration of follow-up was 2–24 months. Histopathologic evaluation was possible in two eyes of one patient. Reactivated or smoldering CMV retinitis crossed the laser scars in 11 eyes, making additional laser coagulation necessary. In four eyes retinal holes in the CMV scar tissue led to retinal detachment, which stopped at the laser scar. In three eyes the detachment is still controlled by the laser scar. In one eye, the detachment stopped at the laser scar for 6.5 months and then slowly progressed across it. There were no complications associated with our laser treatment. · Conclusion: Prophylactic argon laser coagulation in quiescent CMV retinitis seems to reduce the rate of progressive retinal detachment with no need for vitrectomy and silicone oil tamponade.

A randomized prospective study of rhegmatogenous retinal detachment cases treated with cryopexy versus frequency-doubled Nd:YAG laser-retinopexy during episcleral surgery

PURPOSE: To evaluate the efficacy of cryopexy versus transpupillary frequency-doubled (532 nm) Nd:YAG laser-retinopexy according to anatomic and functional success and postoperative complications. METHODS: Seven hundred three patients with primary rhegmatogenous retinal detachment were enrolled. They underwent scleral-buckling surgery using randomly transpupillary frequency-doubled Nd:YAG laser or cryotherapy for retinopexy: patients were observed for a period of 6 months. The primary outcome was anatomic success at 6 months. Secondary outcomes included anterior segment complications, posterior segment complications, and postoperative visual acuity. RESULTS: There was no significant difference between the primary and secondary outcomes in the two treatment groups: the anatomic success rate was 83% in the transpupillary frequency-doubled Nd:YAG laser group and 83.1% in the cryotherapy group; the rate of postoperative complications and the postoperative visual acuity results are also similar in the two groups; the only barely statistically significant difference (P = 0.045) was the rate of macular holes, which were present only in five myopic patients treated with transscleral cryopexy. CONCLUSION: Transpupillary frequency-doubled Nd:YAG laser retinopexy, as cryopexy, served as a safe and effective means of creating chorioretinal adhesion during retinal reattachment surgery. The rate of postoperative complications was not influenced by the type of retinopexy.
