Open angle glaucoma has been identified as a risk factor for stroke, but recently researchers have tightened this connection. They analyzed informatoin from the over 1 milliion patients identified in the Taiwan National Health Insurance database, comparing over 4000 patients with OAG to over 20,000 patients without the condition – the data came from a 5 year period.
Almost 15% of the patients identified as having OAG had strokes within the 5 years; only 9.5% of the non-OAG patients had strokes in the 5 year period.
The researchers adjusted the data for demographics and found that OAG patients were 1 1/2 times as likely to suffer a stroke within that time span.
A later study by Dustin French, PhD substantiated this information.
