In this episode, Optic Surgeon breaks down flashes of light (photopsias) for ophthalmology residents and final-year MBBS students. We explore key causes, including posterior vitreous detachment, retinal tear/detachment, ocular migraines, and vascular or inflammatory conditions. The episode details a systematic workup with thorough history, dilated fundus exam with scleral depression, and cause-specific management. A critical board pearl emphasizes the need for an urgent peripheral retinal exam to rule out tears or detachment.
