Phthisis Bulbi—a Clinicopathological Perspective

ABSTRACTPhthisis bulbi denotes end-stage eye disease characterized by shrinkage and disorganization of the eye with the resultant functional loss. The major factors associated with the pathogenesis of phthisis are hypotony, deranged blood-ocular barriers, and inflammation. Common causes include trauma, surgery, infection, inflammation, malignancy, retinal detachment, and vascular lesions. A phthisical globe shows a small squared off shape, opaque and thickened cornea, thickened sclera, neovascularization of iris, cataract, cyclitic membrane, ciliochoroidal detachment, and retinal detachment. Microscopic features include internal disorganization, inflammatory reaction, a reactive proliferation of various cells, calcification, and ossification. Early treatment of the causative etiology is the best strategy available to avoid an eye from going into phthisis. A phthisical eye has no visual potential and cosmetic rehabilitation or symptomatic relief of pain remains the mainstay in the management. The authors p...
