Advanced coats-like retinopathy as the initial presentation of Familial Retinal Arterial Macroaneurysms.

PURPOSE: To describe two young Saudi brothers with bilateral progressive retinal arterial aneurysms and a subtotal exudative retinal detachment with Coats-like presentation in the older sibling as the initial presentation of Familial Retinal Arterial Macroaneurysms (FRAM). OBSERVATIONS: Two young Saudi brothers with a family history of consanguinity presented with the classic clinical presentation and genetic identification of FRAM. In this report, we describe the presence of prominent peripheral retinal capillary changes mimicking Coats' disease. CONCLUSIONS AND IMPORTANCE: FRAM can present similar to bilateral Coats' disease and should be considered in the differential diagnosis of Coats-like retinopathy. The diagnosis of FRAM may have a significant implication because of the associated cardiac abnormality, such as supravalvular pulmonary stenosis, which should be evaluated by echocardiography and managed accordingly.
