Fibrinolytic properties of some optic nerve vessels.

The fibrinolytic activity of posterior ciliary arteries (PCA), dural vessels (DV), central retinal vessels (CRV), and pial plexus (PP) in 18 human eyes was studied by the fibrin-slide technique and PAS staining. Acitvity was measured on the basis of the minimal incubation time at which lysis appeared. A constant pattern of fibrinolytic activity was found. The PCA were the most active, followed by DV, CRV, and PP. With consideration of the assumed antithrombotic role of fibrinolysis, the results suggest that PCA are better protected against occlusion than CRV.

Bilateral pigmented retinopathy following measles: long-term follow-up and possible association with keratoconus.

A case of pigmentary retinopathy following measles is presented with follow-up of 24 years. A 29-year-old man complained of almost complete blindness during measles infection at the age of 5 (1966). Ophthalmoscopy revealed retinal edema with pallor of the optic disc and in a few months pigment alterations gave the fundus a salt-and-pepper appearance. In 1974 and 1985 a pigmentary retinopathy was present with optic atrophy and typical bone corpuscle deposits, and marked impairment of visual function. In 1990 (i.e. 24 years after the onset of symptoms) the fundus shows pigmentary degeneration with optic atrophy and narrowed vessels, ERG is extinguished and visual fields and dark adaptation cannot be recorded owing to amaurosis. The patient also present bilateral keratoconus. The possible association between these two entities, which to our knowledge has not been previously reported, is discussed.
