Short- and Long-Term Effects of an Intensive Inpatient Vision Rehabilitation Program

Histograms of the visual acuity of subjects’ better eye at entry into the vision rehabilitation program.

The boxplot shows the distribution of patients’ visual ability in logits prerehabilitation and at 3 months and 1 year postrehabilitation. The mean visual ability is set at the origin. Visual abilities above the mean are positive, and visual abilities below the mean are negative. In the boxes, the lower line is the 25th percentile, the central line is the median, and the top line is the 75th percentile. Ninety-five percent of the data is included in the lines extending from either side of the central boxes. *Outlying points.

The scatterplot of visual ability, ranging from a low of −1 to a high of 3 logits, shows that some patients benefit more from the rehabilitation program than others and some patients lose more visual ability at 1 year. The solid line is the line of equality where there is no change in visual ability from 3 months to 1 year postrehabilitation. Legend: ----, ±3 standard errors for significant gains (points above the solid line) or losses (points below the solid identity line).
