Glaucoma is the leading cause of preventable blindness, and it is the leading cause of blindness in both the African-American and Hispanic populations.
In the very early stages of glaucoma, dry eyes may be the only symptom.
Peer-reviewed studies suggest that primary open-angle glaucoma, but not ocular hypertension, can be associated with impaired basal (non reflex) tear turnover. Basal tear turnover values have been found to decrease with the increasing vertical or horizontal optic cup/disk ratios associated with glaucoma. Therefore, dry eye complaints should never be ignored since they could be associated with tear film deficiencies caused by unidentified open-angle glaucoma.
A surprising number of studies also suggest that lower basal tear turnover, decreased tear breakup times (TBUT), smaller values in Schirmer\’s, and higher distribution in the scores of Rose Bengal staining in glaucoma patients who use beta blocker eye drops (glaucoma prescription meds) for more than a few months.
