Purpose: To demonstrate the utility of Optos ultra-wide field imaging in the diagnosis and management of choroidal melanoma in the setting of asteroid hyalosis. Design: Observational case report. Method: A 52-year-old female was referred for evaluation of floaters, photopsias, and blurry vision in the right eye. Clinical examination revealed dense asteroid hyalosis obscuring the fundus, and a limited view of a pigmented choroidal lesion in the nasal periphery. Optos ultra-wide field fluorescein angiography and ultrasonography facilitated the diagnosis of a choroidal melanoma. Results: The patient underwent Iodine-125 brachytherapy for local tumor control and excellent tumor response was confirmed with serial follow-up Optos imaging and ultrasonography. Conclusion: Ultra-wide field fundus fluorescein angiography facilitated the diagnosis of a choroidal melanoma, which was obscured by dense asteroid hyalosis, allowing for local tumor control with brachytherapy. Optos wide-field imaging may be a valuable tool for detecting potentially life-threatening lesions in the setting of asteroid hyalosis.
