[Multimodal imaging in toxoplasmic external punctate retinitis: about a case]

Area of Science:

• Ophthalmology
• Infectious Diseases
• Retinal Imaging

Background:

• Toxoplasma chorioretinitis can manifest in various forms.
• Punctuate Outer Retinal Toxoplasmosis (PORT) is a rare clinical presentation.
• Accurate diagnosis is crucial for effective management.

Observation:

• A 21-year-old presented with decreased vision in the left eye.
• Examination revealed characteristic yellowish-white lesions and vitreous haze.
• Multimodal imaging confirmed PORT in the left eye.

Findings:

• The patient's left eye showed suprafoveolar and peripheral lesions.
• The right eye had a historical pigmented lesion.
• Treatment with antibiotics and corticosteroids resulted in a positive outcome.

Implications:

• This case highlights the diagnostic utility of multimodal imaging in differentiating PORT.
• Early and accurate diagnosis of PORT is essential for visual recovery.
• Understanding rare toxoplasmosis variants improves clinical management strategies.
