ASOCIATION BETWEEN RETINAL MORPHOLOGICAL CHANGES ON OCT AND VISUAL ACUITY OUTCOMES OF MACULA-OFF RHEGMATOGENOUS RETINAL DETACHMENT

Abstract

Objectives: To investigate the association between retinal morphological changes on Spectral-domain Optical Coherence Tomography (SD-OCT) and postoperative visual outcomes in patients with macula-off rhegmatogenous retinal detachment (RRD). Subjects and Methods: A prospective descriptive study was conducted on 41 eyes of patients presenting with macula-off rhegmatogenous retinal detachment treated at Ho Chi Minh City Eye Hospital. Results: The study recorded 41 eyes with macular involvement retinal detachment. Postoperatively, IS/OS junction disruption accounted for 56.1% (23/41), external limiting membrane (ELM) disruption accounted for 34.2% (14/41), and epiretinal membrane (ERM) formation accounted for 12.2% (5/41). Multi-variance linear regression analysis was carried out with stepwise modelling for determining which factors influence the postoperative visual acuity outcome that the duration of symptoms (β=0.004; P=0.017), height of retinal detachment (β=0.0004; P=0.001), postoperative IS/OS disruption (β=0.179; P=0.036), and ERM formation (β=0.231; P=0.003) were significantly associated with postoperative visual outcomes. Conclusion: Factors such as the duration of symptoms, disruption of the IS/OS junction and the external limiting membrane, the presence of intraretinal fluid, and outer retinal undulations are crucial prognostic indicators for postoperative visual recovery.
