Vitreous Degeneration with Flashes of Light in the Dark Requires Urgent Medical Attention

An increasing number of patients are currently visiting ophthalmologists due to vitreous degeneration (vitreous floaters). Symptoms include seeing floating black spots or cobweb-like shapes that resemble smudges on a window, which become particularly noticeable when looking at bright, plain surfaces, solid-colored walls, or the clear sky.

If complications develop—such as a retinal tear—symptoms will include seeing flashes of light or lightning-like flashes in the dark, whether the eyes are open or closed. As vitreous degeneration progresses, the vitreous gel pulls away from the retina, causing a retinal tear that may lead to localized bleeding, which appears as floating spots obstructing vision. A retinal tear is a dangerous condition that can ultimately lead to retinal detachment.

The causes of vitreous degeneration include advancing age, myopia (nearsightedness), eye trauma, diabetic retinopathy, and intraocular inflammation. If you experience a sudden increase in floating spots, flashes of light in the affected eye, or a dark curtain-like shadow obscuring any part of your visual field, you should seek immediate medical attention from an ophthalmologist.
