T. Sharma et al., A MULTIVARIATE-ANALYSIS OF ANATOMIC SUCCESS OF RECURRENT RETINAL-DETACHMENT TREATED WITH PNEUMATIC RETINOPEXY, Ophthalmology, 104(12), 1997, pp. 2014-2017
Purpose: The purpose of the study is to determine the success rate of
pneumatic retinopexy (PR) after failed scleral buckling and to elucida
te the predictors for anatomic failure by multiple logistic regression
analysis. Methods: Thirty-six eyes with recurrent retinal detachment
after failed scleral buckling underwent PR. Intraocular tamponade was
attained with SF6 (20 eyes), C3F8 (13 eyes), and air (3 eyes). Median
follow-up was 14 months. Results: Retinal reattachment was obtained in
69.4%. Multivariate analysis identified two risk factors for failure:
location of retinal break either on the posterior slope or posterior
to buckle (P = 0.01) and extent of retinal detachment greater than two
quadrants (P = 0.02). Conclusions: Pneumatic retinopexy is an effecti
ve alternative to revision surgical operations if the leaking retinal
break is located on the buckle.
