Sudden decline in eyesight led to MS diagnosis 

Diane O'Leary was diagnosed with multiple sclerosis in her early 30s. With two young children at the time, she put her early symptoms down to her busy lifestyle

When Diane O’Leary woke one Friday morning in May 2013 to discover she was losing sight in one eye, she thought she hadn’t properly wiped away her eye make-up.

But, with her sight deteriorating through the morning, the Killarney-based mother, then in her early 30s, visited her GP.
