The overall prevalences of microvascular complications and their association with dietary, clinical, and metabolic characteristics have been studied in 503 Mexican type II diabetic subjects. Average daily dietary intakes were 1866 kcal, 46.5% as carbohydrate, 13.7 mmol cholesterol, 8.7 g fiber, and a polyunsaturated/saturated fat ratio of 0.98. Prevalence rates of microvascular and metabolic complications were as follows: background retinopathy 12.3%, exudative retinopathy 24.2%, proliferative retinopathy 8.1% (1% blind, 4% able to read large print only), 9.1% of patients had cataract, 15.9% nephropathy, and 40.8% peripheral neuropathy. In addition, 3.6% had experienced transient lower motor neuron facial paralysis and 0.2% oculomotor paralysis. Patients with retinopathy had a longer mean duration of diabetes, were less obese at the time of examination, and had higher initial and mean blood pressures and higher mean fasting blood glucose levels when compared with those without retinopathy. Similar differences were observed between groups with and without nephropathy except that mean blood glucose levels were similar in the two groups. The presence of peripheral neuropathy was associated with longer duration of diabetes, less obesity, higher mean blood pressure and mean blood glucose levels, and lower hemoglobin concentration. Patients treated with diet alone had significantly lower prevalences of all three microvascular complications but they also had significantly shorter duration of diabetes and lower mean blood glucose levels. However, multivariate analyses on the subgroup of 360 patients who had repeated fasting blood glucose measurements for at least 5 yr demonstrated associations between retinopathy and duration of diabetes, mean blood pressure and mean blood glucose, and percent calories from carbohydrate.(ABSTRACT TRUNCATED AT 250 WORDS)

Eye movement tests (saccade tests: reaction time, peak velocities and accuracy, and the eye tracking test) were studied in 53 insulin-dependent diabetic (IDDM) patients and 42 randomly selected non-diabetic control subjects, aged between 20 and 40 years. All subjects had central visual acuity of at least 0.1 in one eye, and none had ophthalmoplegia. The reaction time was longer and the accuracy decreased in the saccade test in diabetic patients as compared to control subjects. Peak velocities tended to be slower in diabetic patients, but no significant differences between diabetic and non-diabetic subjects were observed. The maximum eye movement velocities were reduced at all target velocities in diabetic patients as compared to control subjects. These findings can be explained on the basis of many potential disturbances in the central nervous system. Only the duration of diabetes had a clear association with maximum smooth pursuit eye movement velocities in the eye tracking test. Microvascular complications (retinopathy, nephropathy), autonomic neuropathy or metabolic control (high fasting blood glucose and glycated hemoglobin A1c) had no clear association with the results of eye movement tests. In conclusion, insulin dependent diabetes mellitus deteriorates the visuomotor responses.

We measured oxygen consumption in the exercising lower limb by using noninvasive tissue oximetry with the near-infrared spectra of hemoglobin in the quadriceps muscle during bicycle ergometer exercise in four normal controls and three patients with chronic progressive external ophthalmoplegia (CPEO) as well as one patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS). Normal controls showed constant oxygenation during exercise and a rapid recovery after exercise. However, all four patients with mitochondrial myopathy showed abnormal oxygenation during exercise and a slow recovery afterward. The results reflected the defect in oxidative phosphorylation and the impairment in oxygen utilization in those patients. The distinctive patterns of imbalance between oxygen delivery and utilization correlated well with the severity of mitochondrial myopathy as judged by the sum of the serum lactate and pyruvate content during exercise. Noninvasive tissue oximetry may be useful to measure the severity of myopathy and exercise intolerance in patients with mitochondrial myopathy.
