We present the case of a glaucomatous young patient with onchocerciasis who
developed a bilateral pre-equatorial scleral staphyloma with an important
scleral thinness. The pathogenesis of anterior staphyloma is discussed: mec
hanical stress from very high ocular pressure, ocular onchocerciasis, scler
al ischemia. A better undersranding of scleral mechanical resistance could
explain scleral thinness without any clinical scleritis.
