OCT-Based Description of Spontaneous Reattachment of Macula-Off Tractional Retinal Detachment With Significant Vision Improvement.

Purpose: To describe the clinical course and optical coherence tomography (OCT) features of patients with spontaneous reattachment of macula-off tractional retinal detachments (TRDs). Methods: Findings on clinical examination and OCT were evaluated. Results: Four eyes of 4 patients with a history of macula-off TRD secondary to diabetic retinopathy (n = 3) or sickle cell retinopathy (n = 1) were included. OCT confirmed spontaneous resolution of the macular RD without complete posterior vitreous separation in all eyes. The median (interquartile range [IQR]) time from TRD diagnosis to OCT-confirmed foveal reattachment was 6 months (10.25; range, 1-12 months). The median logMAR visual acuity (VA) at the time of macula-off TRD was 0.544 (IQR, 0.452; Snellen 20/70), which improved to 0.350 (IQR, 0.156; Snellen 20/45), with reattachment characterized by OCT ( P  = .068). Conclusions: Nonsurgical spontaneous retinal reattachment and significant VA improvement can occur in eyes with a TRD, albeit rarely. In these cases, no OCT evidence of posterior vitreous separation was found, suggesting that some relaxation of the contractile fibrovascular membranes occurred.
