Seeing small flashes of light is a sign of what?

• A. Glaucoma
• B. Retinal Detachment
• C. Cataracts
• D. Diabetic Retinopathy

Answer: (B)

Seeing small flashes of light is a warning sign of retinal detachment. These flashes, called photopsias, happen when the retina is pulled or torn by the vitreous gel inside the eye. When the retina starts to detach, light entering the eye can create brief, spark-like sensations. This is an urgent emergency because delaying treatment can lead to permanent vision loss, so seeking immediate evaluation by an eye specialist is essential. In contrast, glaucoma often presents with halos around lights or gradual vision loss from optic nerve damage; cataracts cause blurry vision and glare without sudden flashes; diabetic retinopathy typically causes floaters, blurred vision, or blind spots due to changes in retinal blood vessels, not the sudden flashes described here.
