In a patient with diabetic retinopathy, which history finding suggests retinal involvement?

• A. Blurred or fluctuating vision with peripheral field loss
• B. Acute eye pain and redness
• C. Photophobia with tearing
• D. Floaters only without vision change

Answer: (A)

Blurred or fluctuating vision with peripheral field loss points to involvement of the retina. Diabetic retinopathy damages retinal microvasculature, leading to macular edema (causing central blur) and ischemia that can produce field loss as the retina is affected more broadly. This contrasts with symptoms like acute eye pain and redness (more typical of anterior segment inflammation or infection), photophobia with tearing (often corneal or uveal involvement), or floaters without vision change (which may be benign vitreous detachment or require evaluation only if vision is affected). So this kind of vision change directly reflects retinal dysfunction from diabetic retinopathy.
