Bacillary Layer Detachment in Diabetic Retinopathy: A Case Report.

ABSTRACT

To our knowledge, this is the first report to describe bacillary layer detachment (BLD) in a patient with diabetic retinopathy treated with anti-vascular endothelial growth factor. We present the case of a 55-year-old diabetic female who was referred to our hospital complaining of decreased vision in her left eye for 2 weeks. Fundus examination of both eyes was compatible with diabetic retinopathy. Spectral-domain optical coherence tomography of the left eye showed a large dome-shaped cystic space with marginal septa, splitting the myoid zone, consistent with the BLD phenotype. A single dose of intravitreal bevacizumab injection was administered. After 4 weeks, BCVA was improved significantly with complete resolution of BLD. Underlying choroidal ischemia in patients with different vascular disorders like diabetes mellitus may lead to photoreceptor stress and BLD. This study adds to the growing literature, which describes BLD as a marker of fluid accumulation in relation to several macular diseases.
