What is the term for separation of the retina from the choroid?

• A. Ptosis
• B. Retinal Detachment
• C. Strabismus
• D. Incus

Answer: (B)

Separated from the choroid describes retinal detachment. The retina is the light-detecting layer at the back of the eye, and the choroid underneath it supplies its blood and nutrients. When the retina peels away, it can no longer receive these essential controls and nutrients, leading to vision changes such as sudden floaters, flashes, or a curtain-like loss of vision. This is an eye emergency because delaying treatment can cause permanent vision loss. The other terms refer to different structures or conditions: ptosis is drooping of the eyelid, strabismus is misalignment of the eyes, and the incus is a bone in the middle ear, none of which describe the retina separating from the choroid.
