Cytological study on vitreous extracts in Eales disease / 中华实验眼科杂志

ABSTRACT

To study the pathcytological mechanism of Eales disease and to provide a histological testimony for an effictive therapy.Methods45 cases(48 eyes) of Eales disease that were diagnosed according to vitreous hemorrhage and proliferative vitreoretinopathy or secondary retinal detachment.Cytomorphological examination was taken and vitreous extracts were examined by immunohistochemical staining.ResultLymphocytes and fibroblastes were most of those cells in the vitreous extracts.Immunohistology and electron microscopy revealed that lymphocytes were 78.8% or 61.5% in all specimens,respectively.ConclusionProliferative vitreoretinopathy induced by Eales disease closely relates with lymphocytes.The results suggested that autoimmunity might play an important role in the pathogenic mechanism of the disease
