Which condition occurs when the layers of the retina separate?

• A. Nystagmus
• B. Retinal detachment
• C. Otosclerosis
• D. Presbycusis

Answer: (B)

Retinal detachment happens when the retina, the light‑sensitive layer at the back of the eye, peels away from its normal position. This separation lets fluid get between the layers, so the retina lifts away from the underlying tissues that supply blood and nutrients. When this contact is lost, the photoreceptor cells can no longer function properly, leading to vision loss in the affected eye. Common warning signs include a sudden increase in floaters, flashes of light, or a shadow or curtain moving across part of your vision. It’s an emergency: urgent treatment is needed to reattach the retina and preserve vision, often using laser or cry therapy to seal tears, followed by surgical procedures if necessary. Other options describe conditions not related to the retina separating—nystagmus involves involuntary eye movements, while otosclerosis and presbycusis affect hearing.
