The number of participants who experienced SMVL in at least 1 diabetic retinopathy (DR) study eye. SMVL was a ≥15-letter decrease from baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) that was sustained for the last 6 months of the study. Best-corrected ETDRS VA was measured at 4 meters (m) using an eye chart with 5 letters per row of decreasing letter size in each successive row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If <20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed. Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly).

All enrolled participants.

The number of participants whose best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) in at least 1 diabetic retinopathy (DR) study eye decreased by 15-letters or less from the conclusion of Study MBCM to the start of Study MBDV, 6 to 18 months later. Best-corrected ETDRS VA was measured at 4 meters (m) using an eye chart with 5 letters per row of decreasing letter size in each successive row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If <20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed. Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly).

The number of participants who experienced SMVL, long term, in at least 1 diabetic retinopathy (DR) study eye. Long term SMVL was a ≥15-letter decrease from Study MBCM baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) that was sustained for the last 6 months of Study MBDV. VA was measured at 4 meters (m) using an eye chart with 5 letters per row of decreasing letter size in each successive row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If <20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed. Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly).

Participants who were treated with 32 milligram (mg) ruboxistaurin once daily in Study MBCM and had at least 1 DR study eye, who were also enrolled in Study MBDV.

An mSMVL event was defined as a ≥15-letter decrease from Study MBDV baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) during any 6-month period, not just the last 6 months of the study. An mSMVL event was the first occurrence of an mSMVL in a participant, and the time at which the mSMVL began was used as the time of the event for the analysis. VA was measured at 4 meters (m) using an eye chart with 5 letters per row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If <20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed.

All enrolled participants (pts) at risk during the specified intervals. Pts who did not experience an event during the interval were censored to the last time point in the interval. Number of pts censored: 0 to 6 months = 2 pts, 6 to 12 months = 4 pts, 12 to 18 months = 9 pts, 18 to 24 months = 82 pts, and 24 to 30 months = 90 pts.

Best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) was measured at 4 meters (m) using an eye chart with 5 letters per row of decreasing letter size in each successive row. Participants read the chart from the top down until reaching a row where ≥3 letters in the row could not be read correctly. If <20 letters were read correctly at 4 m, the chart was re-read at 1 m. The best-corrected ETDRS VA score was the total number of letters read correctly per eye at 4 m, plus a correction factor of 30 if ≥20 letters were read correctly at 4 m, plus the total number of letters read correctly at 1 m, if assessed. Best-corrected ETDRS VA scores ranged from 0 (no letters read correctly) to 100 (all letters read correctly). A higher score represented better VA.
