Applanation-Schiøtz disparity after retinal detachment surgery utilizing cryopexy.

Previous reports of applanation-Schiøtz disparity following retinal detachment surgery involved patients whose detachments were treated with diathermy and scleral buckling. In 73 patients with retinal detachments treated by cryopexy and scleral buckling, applanation and Schiøtz pressures were measured before and after surgery. In the postoperative period, applanation tension values were significantly higher than Schiøtz values in the operated eyes only; the mean disparity was 6 mm Hg, with a range of 0 to 14 mm Hg.
