MANAGEMENT OF HYPOTONOUS CYCLODIALYSIS WITH PARS-PLANA VITRECTOMY, GAS TAMPONADE, AND CRYOTHERAPY

BACKGROUND AND OBJECTIVE: Cyclodialysis after ocular trauma or surgery may lead to hypotony and visual loss. A new surgical approach for the treatment of cyclodialysis is reported. PATIENTS AND METHODS: In thre e patients with long-standing cyclodialysis and hypotony, a pars plana vitrectomy with gas tamponade and transscleral cryotherapy to the reg ion of the cleft was performed. RESULTS: In all patients intraocular p ressure increased to normal or near normal, choroidal detachment and r etinal and disc edema resolved, and visual acuity increased. CONCLUSIO N: A hypotonous cyclodialysis can be successfully treated with vitrect omy, gas tamponade, and cryotherapy. This approach may be superior to other techniques if there are also additional posterior segment: probl ems or if there is lens dislocation.
