Approach to Flashes, Floaters, Spots¶
Jonathan A. Barnett
- This flowchart is meant to serve as a guide. Bear in mind that there are always exceptions.
- Scintillating or colorful lights/spots, especially if bilateral, are likely migrainous in nature.
- A patient may say they see a visual disturbance in the left eye, when in reality it is in the left visual field of both eyes (indicating that it is a neurological issue, e.g., migraine). Ask if the patient has tried closing one eye to see if the visual phenomenon is actually in one eye.
- Rapid onset of floaters, often preceded by a peripheral crescent-shaped light flash, is classic for posterior vitreous detachment. A black curtain or veil that comes down in the vision is classic for retinal detachment.
