Toxoplasmosis affecting vision most commonly presents as which retinal symptom?

• A. Blurred Vision (Retina).
• B. Increased Visual Acuity With Color Enhancement.
• C. Peripheral Tunnel Vision Without Retina Effects.
• D. No Effect on Vision.

Answer: (A)

Toxoplasmosis in the eye causes a focal inflammatory lesion in the retina (often near the macula) with associated vitreous inflammation. This central retinal involvement disrupts the clarity of vision, so the most common retinal symptom is blurred vision. The other options don’t fit because toxoplasmosis does not typically improve vision, cause peripheral tunnel vision without retina effects, or leave vision completely unaffected. Patients may also notice floaters from the inflammation, but the key vision change is blurred vision due to central retinal involvement.
