Experimental posterior uveitis. II. Electroretinographic studies.

Experimental posterior uveitis. II. Electroretinographic studies.

Experimental posterior uveitis was induced by the inoculation of retinal S-antigen into black hooded Lister rats. The time course of the disease was monitored by electroretinography (ERG), and the ERG changes were correlated with clinical signs and underlying pathological damage. The ERG became supernormal in the third week after inoculation, with some loss of temporal resolution (lowered ERG f...

Occlusion of posterior ciliary artery. IV. Electroretinographic studies.

The effects of posterior ciliary artery (PCA) occlusion have been studied in rhesus monkeys by Hayreh and Baines (I972 a, b, c), who reported the effects of occlusion of the medial PCA, lateral PCA, and all the PCAs on the choroidal circulation (Hayreh and Baines, I972a) and optic nerve head (Hayreh and Baines, I972C), and the productionof chorioretinal lesions (Hayreh and Baines, 1972b). Their...

Neovascularisation associated with posterior uveitis.

Twenty-six patients (39 eyes) with retinal neovascularisation associated with ocular inflammation were identified from the retinal vasculitis clinic at St Thomas's Hospital. Eight patients had sarcoidosis, seven patients Behçet's disease, and 11 had idiopathic retinal vasculitis. Twenty-three patients had required systemic therapy to control the inflammation and 11 patients received laser photo...

Rapidly blinding posterior tubercular uveitis

BACKGROUND A 21-year-old female patient had chorioretinitis in the left eye which relapsed while being on anti-tubercular treatment and oral corticosteroids leading to blindness and the loss of the left eye. FINDINGS Mycobacterium tuberculosis causing chorioretinitis showed a poor response, and the lung lesions showed a good response to the same anti-tubercular treatment. CONCLUSIONS Mycoba...
