Objective To investigate the clinical manifestation and histopathologic changes of the fungal necrotizing retinochoroiditis. Methods Collecting 7 cases of fungal retinochoroiditis with severe immunodepression and loss of visual acuity.Seven removed eyeballs were stained with HE,PAS and silver methenamine,and observed by light microscopy,and in addition,2 of them examined by electron microscopy.Also fungal cultures of blood and affected tissues were performed. Results The chief clinical macnifestation included ciliary injection of conjunctiva,opaque aqueous fluid and vitreous and diffuse hemorrhage and greyt white opacity with retinal detachment in severe cases.Pathologic changes included hemorrhage in the retina,chorioretinal tissue necrosis,hyphae in the blood vessels,affected tissue and vitreous.Fungal culture of blood was positive in three cases.Culture of affected tissues was positive in all cases. Conclusions Eedogenous fungal infection of choroid and retina may be due to the severe immunodepression of the sufferers and usually causes chorioretinal tissue destruction and blind.
