Abstract

Scleral tissue from a nanophthalmic patient was examined morphologically and by a tissue culture method. Collagen in the unusually thickened scleral tissue was arranged in irregularly interlacing bundles. Results of tissue culture studies showed sclerocytes that seemed to secrete many granules that stained positively with Alcian blue and periodic acid-Schiff (PAS). No granules were seen in cells of scleral tissue cultured from two control eyes. These findings may be the result of the modified glycosaminoglycan metabolism, which in turn contributes to the abnormal packing of collagen bundles and thickening of sclera in nanophthalmos.
