The change in the thickness of the central zone of the retina after vitrectomy due to rhegmatogenous detachment of the retina using silicone tamponade

Changes in the thickness of the retina in the central zone with silicone oil tamponade of the vitreous cavity after vitrectomy due to rhegmatogenous retinal detachment of the retina using silicone oil tamponade were detected in the early postoperative period. A decrease in the thickness parameter of the outer layers of the retina in the fovea zone was detected already on the 3rd day of postoperative observation (p = 0.044). Moreover, on the 14th day in the fovea zone, a decrease in retinal thickness appeared both in the outer (p = 0.048) and in the inner (p = 0.002) layers in comparison with the control group. The decrease in the thickness of the retina in the early postoperative period in the parafovea zone showed a different dynamics. The thickness of the inner layers in the superior hemisphere in this zone was significantly reduced on the 3rd day in comparison with the control group (p = 0.035), followed by a significant decrease in thickness by the 14th day as compared with the parameters in the control group (p = 0.009), and the early postoperative period (p = 0.034). The thickness of the outer layers of the retina in the superior hemisphere of parafovea significantly decreased on the 14th day after surgery (p = 0.033). In the inferior hemisphere, a decrease in the thickness of the inner layers was detected on the 14th day of postoperative observation (p = 0.016), and the thickness of the outer layers at all periods of postoperative observation did not change significantly (p> 0.05).
