Which condition involves separation of the neurosensory retina from the underlying pigment epithelium, causing flashes and curtain-like loss of vision?

• A. Diabetic retinopathy.
• B. Retinal detachment.
• C. Cochlea.
• D. Eustachian tube.

Answer: (B)

Retinal detachment happens when the neurosensory retina separates from the underlying pigment epithelium. This separation disrupts the retina’s ability to process light signals, so people often notice sudden flashes of light and a curtain-like block of vision that spreads across part of the visual field as the detached area pulls away. The onset is typically painless, but it’s a medical emergency because prolonged detachment can lead to permanent vision loss. Understanding why this occurs helps: fluid from the back of the eye can seep under the retina after a tear, or traction from scar tissue can pull the retina away from its normal position. Quick eye examination by an ophthalmologist can confirm the detachment; sometimes ultrasound is used if the eye’s interior can’t be clearly seen. Treatment aims to reattach the retina and prevent further damage. Depending on the case, this may involve sealing any retinal tears with laser therapy or freezing treatment, followed by surgical options such as a scleral buckle, vitrectomy, or pneumatic retinopexy to encourage the retina to reattach. The other options relate to different parts or diseases and do not produce the characteristic retina separation and the associated flashes and curtain-like vision loss.
