Diabetic neuropathy and braille ability.

Thirty-five individuals with visual impairment due to diabetic retinopathy underwent neurologic examination with special emphasis on two-point discrimination and nerve conduction studies to determine whether concomitant peripheral neuropathy would interfere with their ability to read braille. Twenty-two individuals with insulin-dependent diabetes mellitus (9 men and 13 women) and 13 with noninsulin-dependent diabetes mellitus (4 men and 9 women) were evaluated. All had peripheral neuropathy; there were 4 with stage 1, 29 with stage 2, and 2 with stage 3 neuropathy. Two-point discriminatory ability appeared to be relatively well-preserved and at least 25 of the 35 individuals were able to learn to read standard or jumbo braille. Individuals with abnormalities in two-point discrimination (greater than 5 mm) were found to have abnormalities in braille reading. Individuals with visual impairment due to diabetes should not be discouraged from undertaking braille on the basis of apparent polyneuropathy.

Exercise training in individuals with diabetic retinopathy and blindness.

Limited guidelines exist for rehabilitation programs for individuals with diabetes mellitus, blindness, and associated autonomic neuropathy. Abnormalities in autonomic function have been postulated to interfere with exercise conditioning and may predispose individuals to exercise-induced hypoglycemia. Twenty-nine individuals with diabetes mellitus underwent standardized noninvasive testing for the evaluation of cardiovascular autonomic function and graded exercise before entering a rehabilitation program. Inadequate responses of heart rate to respiratory variation were observed in 28 patients, abnormal heart rate responses to postural maneuvers were seen in 23, and postural hypotension was noted in nine. Individuals with symptomatic postural hypotension were able to exercise using a stationary bicycle, but developed hypotensive episodes on walking or prolonged standing. Blood glucose consistently decreased by a mean of 76 (+/- 9) mg/dl after each exercise session, even though low levels of exercise were performed (2.9 +/- 0.2 metabolic equivalents, for 28 +/- 1 min). There was no relationship between the degree of autonomic neuropathy and the level of blood glucose fall. There was, however, a significant correlation (r = -0.59, p = 0.001) between the decrease in blood glucose level and the amount of regular insulin used in the routine morning dose. Precautions were taken to avoid hypoglycemia, and insulin and diet were adjusted accordingly to prevent severe hypoglycemic reactions.

A model clinical program for patients with diabetes and vision impairment.

A program was developed to improve independence, self-esteem, and glycemic control in patients with diabetes and blindness. Twenty-nine individuals with both insulin-dependent and noninsulin-dependent diabetes mellitus entered 12-week programs that included education focusing on diabetes self-management skills for the visually impaired, monitored exercise sessions, and group support. Glycated hemoglobin values fell from 13.0% +/- 0.6% (SEM) to 11.4% +/- 0.5% (P = .001). Exercise tolerance in a 12-minute walk test improved from 0.48 +/- 0.04 to 0.64 +/- 0.05 miles (P = .001). Marked improvements occurred in psychosocial indices, demonstrated through changes in the Rand Mental Health Index from 155 +/- 6 to 174 +/- 5 (P = .0001), the Rosenberg Self-Esteem Scale from 22 +/- 1 to 19 +/- 1 (P = .001), the Zung Depression Scale from 0.50 +/- 0.02 to 0.44 +/- 0.02 (P = .001), and the Diabetes Self-Reliance Test from 60 +/- 3 to 74 +/- 2 (P = .0001).

Psychosocial profiles in patients with visual impairment due to diabetic retinopathy.

The psychological impact of vision loss due to diabetic retinopathy is compounded by the loss of diabetes self-management skills. The appropriate role and timing for rehabilitative intervention has not been determined. Twenty-nine individuals with diabetes mellitus, 16 with stable visual impairment and 13 with fluctuating and transitional visual impairment, underwent psychological assessment before and after entering into a specially designed rehabilitation program. Low levels of performance were rehabilitation program. Low levels of performance were demonstrated by the Rosenberg Self-Esteem Scale and the Diabetes Self-Reliance Test in both groups. The Minnesota Multiphasic Personality Inventory, the Zung Self-Rating Depression Scale, and the Rand Mental Health Index suggested that subjects with stable vision impairment were moderately compensated relative to the transitional group, although the former group may have been totally blind. Both groups demonstrated significant improvements in psychological profiles after the program. It is suggested that a rehabilitation program may be of clinical benefit early in the course of vision loss associated with diabetic retinopathy.

Cardiovascular conditioning in individuals with diabetic retinopathy.

The benefit of exercise for individuals with diabetes mellitus and high-risk complications of retinopathy has been questioned. Thirty-nine individuals with diabetes and visual impairment completed a 12-wk rehabilitation program that included cardiovascular conditioning. Pre- and postprogram assessment of exercise training in 30 subjects included a graded stress test with a bicycle ergometer. There were improvements in exercise tolerance as measured by the work load achieved (from 248 +/- 27 to 303 +/- 31 kilopond meter [kpm], P less than .05). There was a trend toward improvement in METS achieved (from 3.3 +/- 0.2 to 3.8 +/- 0.3, P = .06). There was no correlation of improvement in exercise tolerance with improvements in glycemic control, lipoprotein balance, and change in body weight. Individuals with diabetic retinopathy may be given the option of entering cardiovascular training programs with appropriate modifications to fit specific needs.
