lary non-perfusion. FFA can give equivocal results as stretched vessels also leak and capillary nonperfusion of the raised peripheral retina is difficult to interpret. Acquired retinoschisis can atypically present with vascular changes. OCT-A is a non-invasive and potentially useful ancillary test in challenging cases. It differentiates anomalous vessels because of traction from neovascularization. We recommend that retinoschisis be included in the differential diagnosis when retinal telangiectasia is found with no apparent cause. We also recommend consideration of OCT-A, where available, as a useful diagnostic modality prior to any invasive investigations.
