Abstract

Purpose: Analyze the correlation between macular lesions observed in post-surgical OCT images and visual outcomes following primary retinal detachment repair for macular-off patients. Method: This prospective, descriptive study was conducted on individuals who were diagnosed with macular-off primary retinal detachment and treated at the Central Eye Hospital. Results: For this study, 59 eyes out of 59 patients were analyzed. During the OCT imaging, which occurred at an average of 2.2 ± 1.2 months post-surgery, 50 eyes had abnormalities, making up 84.7% of the total. The most common lesions were EZ zone lesions (found in 19 eyes, or 32.2%), followed by external limiting membrane lesions (found in 14 eyes, or 23.7%), sub-retinal fluid (found in 9 eyes, or 15.3%), cystoid macular edema (found in 11 eyes, or 18.7%), and epiretinal membrane (found in 10 eyes, or 17.0%). Additionally, 8 eyes (13.6%) had miscellaneous lesions that involved both the external limiting membrane and EZ zone. There is a statistically significant correlation between visual outcome and external limiting membrane, EZ zone, and miscellaneous lesions (p < 0.05). Conclusion: Following a successful surgery to repair macular-off retinal detachment, OCT is a non-invasive imaging diagnostic method that can accurately and effectively assess macular lesions. Lesions such as those on the external limiting membrane, EZ zone, and miscellaneous areas can help determine the potential for vision recovery after surgery.
