What symptom would suggest a retinal detachment?

Flashes of light in vision, known as photopsia, are a classic symptom of retinal detachment. This phenomenon occurs when the retina is stimulated by either traction from the vitreous gel pulling away from the retina or when there are changes in the retina itself due to the detachment. Patients may describe seeing brief, bright flashes, which usually happen in their peripheral vision. This symptom is a critical indication as it suggests that the retina may be in distress, potentially leading to a more severe complication if not evaluated and treated promptly.

Sudden increased sensitivity to light, persistent eye pain, and loss of peripheral vision may not specifically indicate a retinal detachment. Increased sensitivity can occur due to various issues like inflammation or glare but isn't directly tied to retinal detachment. Persistent eye pain could be related to several other eye conditions, and loss of peripheral vision can arise from different retinal issues or optic nerve problems. Therefore, while these symptoms may warrant an eye examination, they do not serve as the hallmark signs of retinal detachment like flashes of light do. Understanding the specific symptoms of retinal detachment is crucial for timely intervention and to prevent vision loss.
