To evaluate retinal and choroidal subfoveal thickness (RST ; CST) variation in healthy subjects who underwent uncomplicated cataract surgery by using Spectralis Optical Coherence Tomograpy (OCT).
Eye Clinic, S.Maria della Misericordia Hospital, S.Andrea Delle Fratte, Perugia, Italy
In this preliminary study, ten patients who underwent uncomplicated cataract surgery were enrolled. Each patient was evaluated by OCT during three (3) different sessions: the first one in the pre-op visit, then, the second, one day after surgery, and finally, the third one, 30 days after surgery. Both eyes in every patient were tested by one experienced examiner (M.L.) with two 20 x 15 degree volume scans per session, consisting of 19 high-resolution line scans (20 frames per scan). The first scan was used to evaluate the RST and the second one, made with the use of Enhanced Depth Imaging (EDI) function, was used to analyze the CST.
In the operated-eye the RST mean and standard deviation (SD) for the preop-scan were 305±31μm and were 306±40μm and 302±32μm in the second and third scan. The absolute change (AC) in RST between the first and the second scan was 0.7±10.7μm while it was 2.3±4.6μm between the first and the third scan. In the operated-eye the CST mean and SD for the preop-scan were 203±94μm and were 220±105μm and 212±102μm in the second and third scan. The AC in CST between the first and the second scan was 2.2±28μm while it was 10±30μm between the first and the third scan. In non-operated eye the RST mean and SD for the first scan were 302±46μm and were 303±41μm and 297±37μm in the second and third scan. The AC in RST between the first and the second scan was 0.7±7.2μm while it was 3.6±11.3μm between the first and the third scan. In the non-operated eye the CST mean and SD for the first scan were 210±64μm and were 207±66μm and 211±59μm in the second and third scan. The AC in CST between the first and the second scan was 2.5±24.8μm while it was 1.5±19.2μm between the first and the third scan.
These preliminary results support the hypothesis that uncomplicated cataract surgery could determine variation both in retinal and choroidal thickness. The wider variation is appreciated in CST, which seems to increase one day after surgery and tends to thin thirty days after the treatment.
