Abstract
Ovjective To observe the surgically excised specimens from eyes with hemorrhagic agerelated macular degeneration (AMD).Methods Thirty-six surgically excised specimens were captured from 36 patients with hemorrhagic AMD,26 specimens were diagnosed as occult choroidal neovascular membrane (CNVM),10 specimens were diagnosed as polypoidal choroidal vasculopathy (PCV).All specimens were routinely processed by hematoxylin and eosin,periodic acid-Schiff's stain and Masson stainings.At the maximum horizontal and vertical slice of the specimens,the category and amount of the cells in the specimen were recorded,as well as the relationship between the specimens and the surrounding tissue.Results The 36 specimens are categorized as neovascular membrane dominant (19/36),collagen fiber dominant (6/36),blood clot dominant (8/36) and degenerated thickened Bruch's membrane dominant (3/36).Eighteen occult CNVM specimens and 1 PCV specimen are categorized as neovascular membrane dominant; all 6 collagen fiber dominant specimens are occult CNVM; 1 occult CNVM and 7 PCV specimens are categorized as blood clot dominant; and 1 occult CNVM and 2 PCV specimens are categorized as degenerated thickened Bruch's membrane dominant.The occult CNVM categorized as neovascular membrane dominant present as small blood vessel with single endothelium cell attached; the PCV specimen categorized as neovascular dominant presents as big blood vessel with thick vessel wall under the Bruch's membrane,retinal pigment epithelium and choroidal melanocyte are both observed in the PCV specimens.Conclusion The components of the specimens captured from eyes with hemorrhagic AMD are diversified.
