Which eye condition occurs when the retina separates from the back of the eye?

• A. Glaucoma
• B. Dry Eye Syndrome
• C. Night Blindness
• D. Retinal Detachment

Answer: (D)

Retinal detachment happens when the retina, the light-sensitive layer at the back of the eye, pulls away from its normal position. The retina needs to stay attached to the underlying tissue to get oxygen and nutrients; if a tear or break allows fluid to seep underneath, the retina lifts off. This disrupts the light-sensing cells and can cause sudden vision changes, making it an urgent emergency to treat to prevent permanent vision loss. People may notice a sudden surge of floaters, flashes of light, or a curtain-like shadow over part of their field of vision that may spread. Treatment aims to reattach the retina and seal the tear, using laser or freezing therapy, pneumatic retinopexy, or more involved surgery like scleral buckle or vitrectomy, chosen based on the detachment’s location and extent. This differs from glaucoma, which involves optic nerve damage from high eye pressure; dry eye syndrome, which is a tear film problem causing irritation; and night blindness, which is trouble seeing in low light from rod dysfunction or vitamin A issues.
