Bacillary Layer Detachment in Unilateral Acute Idiopathic Maculopathy: A Report of 2 Cases

Aim: To report the presence of bacillary layer detachment (BLD) in unilateral acute idiopathic maculopathy (UAIM).Case description: Two patients diagnosed with UAIM based on the clinical and imaging features showed the characteristic splitting of the ellipsoid layer on spectral domain optical coherence tomography (SDOCT). This has been termed as bacillary layer detachment.Results: No treatment was given. In both cases, there was a complete spontaneous resolution of the SDOCT findings 14-days post-presentation in Case 1 and 5-days post-presentation in Case 2 with improvement in visual acuity to 20/20, N6 in both cases.Conclusion: BLD in UAIM is not a commonly reported SDOCT finding and can serve as an imaging biomarker.
