Analyse de la macula par OCT spectral domain dans la chirurgie du décollement de rétine rhegmatogène

Purpose:To analyze the temporal trends in structural changes using spectral-domain optical coherence tomography and functional changes using multifocal electroretinogram after rhegmatogenous retinal detachment surgery.Methods: This prospective cohort study enrolled 69 patients with macula-off rhegmatogenous retinal detachment who underwent successful surgery. Early Treatment Diabetic Retinopathy Study visual acuity, multifocal electroretinogram evaluation of the central 5°, and spectral-domain optical coherence tomography were recorded at 1, 3, 6, and 12 months (M) after surgery. The fellow eye served as the control group for multifocal electroretinogram parameters.Results: Between M1 and M12, visual acuity improved from 64 to 75 letters (P = 0.001) and implicit time of N1 decreased from 27.8 to 25.2 milliseconds (P = 0.001), whereas the other parameters did not vary significantly. Amplitude and implicit time values did not reach normal values at M12. Alterations of the ellipsoid zone and the external limiting membrane decreased over time (P = 0.001). P1 implicit time correlated independently with the alteration of the external limiting membrane (P = 0.007).Conclusion: Foveal wave amplitudes remain lower than normal values after successful surgery of rhegmatogenous retinal detachment, whereas anatomical improvement was found for outer retinal abnormalities and subretinal edema fluid. Retinal recovery improves N1 implicit time over time. Disruption of external limiting membrane seems to be predictive of increased P1 implicit time.

Purpose: To determine the impact of metamorphopsia on quality of life after successful retinal detachment (RD) surgery and to determine which retinal changes are related to the most severe distortions. Design: This was a prospective, observational, consecutive study. Methods: The study included 58 eyes of 58 consecutive patients who underwent successful RD surgery. At 6 months postoperatively, the incidence and severity of metamorphopsia were assessed by a quality-of-life questionnaire. Microstructure retinal changes were studied with spectral domain optical coherence tomography (OCT). The questionnaire score was compared with pre- and postoperative OCT findings. Results: Overall, 20 patients (34.5%) had metamorphopsia. Outer retinal folds (ORFs) and the macular status before surgery, together with postoperative ORFs and decrease in ellipsoid and/or interdigitation photoreceptor zone reflectivity, were identified as risk factors of developing metamorphopsia (relative risk, 1.7–4.8). The most severe visual distortions were associated with ORFs. Conclusion: Metamorphopsia is a frequent occurrence after RD surgery and its impact on patients’ quality of life appears to be limited. While it may be difficult to prevent photoreceptor loss occurring after surgery, limiting postoperative ORFs may be helpful in reducing their incidence.
