Abstract
PURPOSE: To report a case of a 42-year-old male with proliferative diabetic retinopathy (PDR) complicated by tractional retinal detachments (TRD) bilaterally with a rare finding on B-scan ultrasonography. OBSERVATIONS: On B-scan ultrasound, a total combined rhegmatogenous-TRD was observed, accompanied by extensive retinal macrocysts that appeared nearly confluent for 360°. CONCLUSIONS AND IMPORTANCE: Retinal macrocysts are rare but important clinical entities that help drive management, as their presence typically suggests a chronic retinal detachment.
