Long Term Structural and Functional Macular Findings after Scleral Buckling in Adolescent Primary Retinal Detachment Cases Undergoing Laserpexy versus Conventional Cryopexy (A Comparative Study), NEHAL M.S. EL-GENDY
Abstract
Objectives: To compare long term structural and functional macular outcomes in adolescent cases with Primary Rheg-matogenous Retinal Detachment (PRD) receiving either Argon laserpexy or cryopexy.
Material and Methods: Patients between 13 and 18 years with PRD were randomized into 2 groups. In Group A, Argon laserpexy was adopted while in Group B conventional cryopexy was performed. Microperimetry and macular imaging were done using the OPKO Spectral OCT/SLO combination imaging system (OPKO instrumentation, LLC, USA) at least 1 year post-operative.
Results: Forty eight eyes were included (24 in each group). Attachment rate was comparable (91.7% for Group A, 83.3% for Group B, p=0.4). CDVA was significantly better in Group
A,first post-operative week and last follow-up visit. IOP was significantly higher in Group B one week post-operative. Central macular thickness, last follow-up visit, was comparable in both groups (A: 226.5±35, B: 241±57. p=0.3). Epiretinal Membrane (ERM) was found in 13.6% Group A and 10% Group B (p=0.7). Persistant Subretinal Fluid (SRF) was found in 2 cases in Group B (10%). Number of cases with EZ disruption was comparable (15 Group A vs 16 cases Group
B,p=0.4). The mean microperimetric sensitivity was higher in Group A (10.4±3.1 dB, compared to 8.9±3.2 dB) (p=0.04).
Conclusions: Laserpexy could be considered a better alternative to cryopexy in adolescent cases with PRD as regard macular function and microstructure restoration.
