Brief Summary
The purpose of this study is to measure the safety, efficacy and quality of life of lansoprazole in patients with reflux disease over a five year period.

The retinal blood vessels of the right eye were assessed by an Ophthalmologist and judged to be normal or pathological at Baseline and at Year 5. Pathological classification includes abnormal findings such as retinal vascular disorder, retinopathy, and retinal hemorrhage. Normal indicates no pathological findings were observed. The shift table below summarizes the individual transitions in retinal blood vessel classification between Baseline (depicted in the columns) and Year 5 (depicted in the rows).
