Glaucomatous RNFL damage shows symmetry between fellow eyes

Researchers used OCT (Stratus) imaging to examine 77 patients with open-angle glaucoma. They found significant correlations in retinal nerve fiber layer (RNFL) thickness in all sectors and quadrants between fellow eyes. Categorical agreement on defective locations was found mostly in the inferior and superior locations, which corresponds with the typical pattern of early glaucomatous damage. None of the randomly matched nonfellow pairs of glaucomatous eyes that served as controls showed significant correlations.
