Abstract
Retinal detachment (RD) is caused by a tear in the periphery of the retina and the vitreoretinal (VR) traction. Treatment of symptomatic retinal detachment is currently extraocular and intraocular surgery.
We evaluate a set of 17 eyes in 17 patients with RD, who were operated extraocularly / cryosurgicaly. In 12 eyes (71%) were the quadrant RDs (including once with two tears), 2 eyes had ora-abrys, once it was the RD of the lower halve, and 1 patient had a subtotal RD.
In 9 (53%) cases were used type of operation: cryocoagulation with radial plombage and in 8 cases cryocoagulation with cerclage. Primary attaching the retina occurred in 16 cases (94%) and retina remained lying in 14 eyes (82.4%) - in 2 cases occurred re-detachment (11.7%).
The preoperative best corrected visual acuity (BCVA) ranged hand motion - 20/20 and postoperative BCVA was 1/50 to 20/20. Improvement was statistically significant (Wilcoxon p = 0.01).
Cryosurgical procedure in phakic eyes we consider the gold standard surgical treatment for uncomplicated rhegmatogenous retinal detachment. As the main cause of the eventual failure of this technique, we see persistent vitreous traction and proliferative vitreoretinopathy (PVR).
