The changes of choroidal thickness of patients with retinal detachment after scleral buckling using enhanced depth imaging (EDI)-OCT in Isfahan Feiz Hospital in 2015

Background: There is a growing interest in the role of the choroid in various chorioretinal diseases. The aim of this study is to investigate the changes in different area of choroidal thickness (CT) following scleral buckling surgery using Enhanced-depth imaging optical coherence tomography (EDI-OCT). Methods: This prospective clinical study compared 24 patients with Retinal detachment (RD) and 24 control eyes. The macular CT in the sub fovea and in four different regions, superior, inferior, temporal and nasal areas were measured using EDI-OCT at 1000 microns (S1000, I1000, T1000, and N1000). Results: The average age was 52.33±12.72 years (range 30–80 years). There was significant difference between mean subfoveal CT of operated eye in three exams (P<0.05) .This value was significantly larger at before surgery, 1st week and 1st month exams when compared with control eye (P<0.05 for all comparison). All of these thickness significantly decreased at the 1st week and 1st month follow-up exams. Mean CT of operated eye at S1000,T1000, I1000,N1000 locations was 301.68±112.39, 289.89±114.7, 219±57, 276.05±120.76, and 263±111.74μm, respectively before surgery . These macular choroidal thickness in the study eye was larger when compared with the control eye. The differences were statistically significant for the nasal (p=0.009) and superior (p=0.012) locations. Conclusions: Patients with RD had a significantly larger CT that All of these thickness significantly decreased at the 1st week and 1st month follow-up exams.
