Differential diagnosis of posterior uveitis

Diagnostic approach

Fever, lymphadenopathy, myalgias, night sweats, two months ago

Oral ulcer sporadically

1+ cells in AC 3+ haze in vitreous White fluffy lesion

2.5 disc diameters

45-year old male. Floaters and decreased vision since 1 week

BCVA: 0.2 OD, 1 OS IOP: 12mmHg OU

OS within normal limits

Development of a differential diagnosis

Even in cases with typical picture,

we should generate a list of possible diagnoses

• Adamantiades-Behcet’s

• Sarcoidosis

• SLE

• Birdshot chorioretinopathy

• Lymphoma

• Cat scratch disease

• Acute retinal necrosis

• Toxoplasmosis

• Syphilis

• Fungal endophthalmitis

• Tuberculosis

• CMV
