Purpose To identify the cause of reduced visual acuity in patients with successful anatomical result after retinal detachment surgery. Methods We retrospectively reviewed files of patients that underwent retinal detachment surgery in our clinic. Patients with anatomically successful operation and a postoperative visual acuity ≥ 0.18 logMAR were identified. Patients were called and they underwent thorough re‐examination including BCVA after refraction, slit lamp examination, fundus biomicroscopy, OCT and fluorescein angiography if considered necessary. Results We reviewed the files of 78 patients with anatomically successful operation. 26 patients (33%) had a visual acuity better than 0.18 LogMAR. The remaining 52 (67%) patients had a visual acuity ranging from 1.1 LogMAR to 0.18 LogMAR. The reduced visual acuity was attributed to anterior segment problems in 8 patients (15.4%) (in 7 patients to cataract and 1 to bullous keratopathy), to cystoid macular edema in 18 patients (34.6%), to residual subretinal fluid in 5 patients (9.6%), to macular atrophic changes in 5 patients (9.6%), to epiretinal membrane in 11 patients (21.2%), to macular hole in 3 patients (5.8%), to optic nerve atrophy in 1 patient (1.9%) , while in 1 patient (1.9%) no apparent reason for reduced vision was found. Conclusion Macular changes represent the most frequent reason for reduced visual acuity after anatomically successful retinal detachment surgery. Strategies to prevent or improve these alterations might improve the functional result of retinal detachment surgery.
