To evaluate foveal anatomy and microstructure wtih the use of SD-OCT in rhegmatogenous retinal detachment patients, who underwent anatomically successful scleral buckle(SB), pars plana vitrectomy (PPV) or pneumotic retinopexy (PR) surgeries.
Okmeydanı Education & Research Hospital / Istanbul
59 eyes of 59 patients ( mean age: 55,0 ± 14,7 ) were enrolled into this study. 20 eyes had SB surgery, 32 eyes PPV, 6 cases PPV + SB and 1 case PR only. At the end of follow-up ( 8-69 months, mean 36,1 ) all patients were tamponade free, and underwent SD-OCT examination ( Zeiss Cirrus) . OCT findings, best corrected visual acuity (BCVA), fundoscopic and biomicroscopic findings were recorded. Data were evaluated with SPSS statistically.
All cases were reattaced at final visit. Mean BCVA increased in whole group from 1,81 ± 0,90 to 0,82 ± 0,69 logmar postoperatively ( p<0,05 ). The visual gain difference between PPV and SB groups was insignificant(1,13 vs 0,85 ;p>0,05). In 14 eyes (28,5 %) OCT exams revealed no pathological finding. Pathological OCT findings were defined as; inner-outer segment (IS-OS) band ( 47,5%) and external limiting membrane ( ELM ) (47,5%)disruption, retinal pigment epithelium (RPE) disorder( 11,9%), subretinal fluid (SRF)(6,8 %), epiretinal membrane (ERM )(55,9%) and macular edema (ME)(13,6).While in PPV group ME incidence ( 21,9%) was significantly higher than SB group ( 0%), SRF was found in SB ( 20%) group significantly more often than the PPV group (0%). ERM formation was defined more often in PPV group ( 62,5 % vs 35 % ) although statistically insignificant. All pathological OCT findings expect SRF was correlated with lower visual outcome ( p<0,05 ).
SD-OCT enables to discover foveal microstructural changes in reattached retinal tissue. ME and ERM formation are more commonly seen in PPV patients than the SB only cases. The visual outcome determining parameters seem to be the IS-OS band ,ELM and RPE layers. SRF, which is more common in SB only patients, does not effect the final visual outcome.
