POAG linked to pesticide use

A study by French clinicians has suggested that exposure to pesticides and a lack of omega-3 in the diet may be risk factors for primary open angle glaucoma (POAG).

In the study, 339 patients with the condition were assessed by a questionnaire drawn up by ophthalmologists and nutritionists designed to assess a large number of environmental influences.

There was a significant association with frequent use of pesticides during professional life, and low consumption of oily fish and walnuts. An association with smoking 40 cigarettes or more per day was also identified. The authors of the study, in this month's Acta Ophthalmologica, said further investigation was needed to verify these links.
