Question

A young patient developed painless sudden loss of vision which spontaneously improved over a period of 3 months. What is the most probable diagnosis?

• A. Macular hole
• B. Central serous retinopathy
• C. Angle closure glaucoma
• D. Retinal detachment

Hint:

Think of a condition that causes painless central vision loss in young adults and typically resolves on its own within months.

Answer 1

The Correct Option is B

Step 1: Note the key clues in the history.
The patient is young, the vision loss is painless and sudden, and most importantly it improved on its own over 3 months. This pattern of spontaneous recovery is the biggest clue here.

Step 2: Match the clues to central serous retinopathy (CSR).
CSR happens when fluid leaks under the retina from the choroid through a weak spot in the retinal pigment epithelium, lifting up the macula and causing a small area of blurred or distorted central vision. It hits young to middle aged adults, often men under stress, and the classic feature is that the fluid reabsorbs on its own in most cases within 1 to 6 months, restoring vision.

Step 3: Rule out macular hole.
A macular hole causes painless central vision loss too, but it does not resolve on its own. It needs surgery (vitrectomy) to close, so spontaneous improvement over months rules this out.

Step 4: Rule out angle closure glaucoma.
Angle closure glaucoma causes a painful red eye with sudden vision loss, headache, nausea and a fixed mid dilated pupil. This patient has no pain, so this does not fit.

Step 5: Rule out retinal detachment.
Retinal detachment causes sudden painless vision loss too, often with flashes, floaters and a curtain like field defect, but it does not resolve without treatment. It gets worse, not better, if left alone.

Step 6: Final answer.
Only central serous retinopathy fits a young patient with painless vision loss that gets better by itself over a few months.
