The connective tissue from Tenon's capsule of 7 patients who underwent surgery for retinal detachment was studied ultra-structurally. Five patients were 58-70 years old, and 2 were young adults. The Tenon capsules of 6 children and of 2 aged patients without retinal problems were used as controls. In young controls the Tenon capsule was composed mainly of round, smooth collagen fibrils and a few elastic fibers. The collagen fibrils varied in size from 70 to 110 nm. In the aged patients with retinal detachment, the collagen fibrils showed marked variation of size and also abnormalities of shape in 4 out of 5 cases. The diameter of collagen fibrils varied from 32 to 160 nm, and the elastic fibers were fewer as compared with controls. The possibility arises that age-related structural changes of the orbital connective tissue could predispose to retinal detachment.
