Circumscribed choroidal hemangioma is a benign vascular tumor that occurs as an orange-red mass in the posterior pole of the eye. It most commonly causes decreased vision through serous retinal detachment. Diagnosis can be challenging as it is often initially misdiagnosed as choroidal melanoma or metastasis. Imaging such as ultrasound, fluorescein angiography, and MRI help differentiate it from other lesions. Asymptomatic lesions may be observed, while visually threatening lesions require treatment such as photodynamic therapy, laser photocoagulation, or radiotherapy. Factors like delayed treatment and poor initial vision predict a worse visual outcome.
