Purtscher-Like Retinopathy Associated with Synthetic Cannabinoid (Bonzai) Use

Abstract

Purtscher's retinopathy is a microvascular occlusive disease initially described as retinal edema, cotton wool-like exudation, and hemorrhages occurring after severe head trauma. A similar clinical presentation called Purtscher-like retinopathy is associated with systemic diseases instead of trauma. In the present case, ophthalmic eksamination of a patient with complaints of blurred vision related to substance (Bonzai) use revealed bilateral cotton-wool spots. Purtscher-like retinopathy was diagnosed based on fluorescein angiography and optical coherence tomography findings. This is the first case of Purtscher-like retinopathy associated with Bonzai use described in the literature.
