Purpose: To describe the clinical characteristics and posterior vitreous findings of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD).
Methods: Eighty-six eyes from 80 patients who were diagnosed with SRRRD (SRRRD group) and 92 eyes from 92 patients who had undergone successful scleral buckling for rhegmatogenous retinal detachment ( group for comparison) were included. Ultrawide field fundus imaging and spectral domain optical coherence tomography were performed to evaluate fundus characteristics and vitreoretinal interface.
Results: A significant difference was found in the proportion of complete posterior vitreous attachment between the SRRRD and rhegmatogenous retinal detachment groups (44.2% vs. 19.6%, P < 0.001). The incidence of atypical epiretinal tissue (AET) in the SRRRD group was 14% (12 of 86 eyes), whereas none of the eyes in the rhegmatogenous retinal detachment group exhibited AET. In SRRRD eyes with AET, the visual acuity was lower (logarithm of the minimum angle of resolution, 0.51 ± 0.57 vs. 0.14 ± 0.15, P < 0.001), the mean age was higher (years, 61.7 vs. 39.4, P < 0.001), and the SRRRD lesion extent was wider (clock hours, 5.67 vs. 3.70, P = 0.004) than in SRRRD eyes without AET.
Conclusion: Compared with the rhegmatogenous retinal detachment group, the SRRRD group had a higher incidence of posterior vitreous attachment. Furthermore, AET was a significant comorbidity in the eyes with SRRRD, particularly in the elderly and the area of presumed reattachment over two quadrants and was related to worse functional outcomes.
