We successfully treated a patient with uveal effusion syndrome and abnormal sclera with a partial-thickness sclerectomy. Part of the sclera was immediately cultured, and the excised sclera and the cultured cells were examined by electron microscopy. The sclera demonstrated increased glycosaminoglycan-like deposits between the scleral fibers. The cultured scleral cells showed large intracellular glycogen-like deposits, which were not seen in cells cultured from two control scleras. These findings may be the result of a metabolic defect, which causes a thick, impermeable sclera in some cases of uveal effusion.
