Combined Cytomegalovirus Retinitis and Vitreous Hemorrhage in an Immunocompromised Patient

<b>Purpose:</b> This study is aimed at describing a case of combined CMV retinitis and vitreous hemorrhage in an immunocompromised patient. <b>Observations:</b> A 38-year-old male who is known to have HIV presented to our emergency department complaining of decreasing vision in his left eye. Vitreous hemorrhage and preretinal hemorrhage were observed upon examination and were thought to be caused by CMV retinitis. After initial treatment and worsening condition upon follow-up, a diagnosis of combined CMV retinitis and vasculitis was considered and was treated accordingly. <b>Conclusions:</b> The presence of vitreous hemorrhage in immunocompromised patients should not be attributed to just an ischemic vasculitis alone, and the possibility of concurrent infectious retinitis should be looked for carefully to avoid delay in treatment.
