New techniques of viscosurgery with phacoemulsification.

Sodium hyaluronate is a valuable aid for phacoemulsification and intraocular lens insertion. Procedures such as anterior capsulotomy, polishing the capsule, lens adjustment, incision closure, and conversion to planned extracapsular cataract extraction are facilitated when sodium hyaluronate is used. A new method of removing it from the eye is presented.

Medical therapy of metastatic meningococcal endophthalmitis.

We treated a 15-year-old girl who had meningococcal meningitis and metastatic endophthalmitis with large doses of intravenously administered penicillin G. The patient promptly improved with this therapy, and the visual axis completely cleared during the subsequent five months.

Hemoglobin A1 and diabetic retinopathy.

The levels of the minor hemoglobin A1 components were measured in a consecutive series of 102 diabetic patients who were extensively studied for signs of diabetic retinopathy. We found a statistically significant relationship between metabolic control, as reflected by the hemoglobin A1 level, and the severity of diabetic retinopathy in patients with diabetes diagnosed before 30 years of age (P less than or equal to .001). We did not demonstrate a significant correlation between metabolic control and the severity of retinopathy in patients with diabetes diagnosed after the age of 30 years. We found significantly more severe retinopathy among patients with longer duration of the disease, in men, in whites, in diabetics diagnosted before 30 years of age who were treated with lower insulin doses, and in obses patients with the onset of diabetes after the age of 30 years.

Metabolic control in diabetic patients. Effect of insulin-secretory reserve (measured by plasma C-peptide levels) and circulating insulin antibodies.

We measured circulating hemoglobin A1 (HbA1) and fasting plasma C-peptide concentrations in 100 diabetic patients. Pancreatic insulin reserve showed a negative correlation with HbA1 concentrations in nonobese, insulin-treated patients but not in obese patients, whether they were treated with insulin, oral agent, or diet alone. Patients with fasting C-peptide concentrations above 0.1 pmol/ml had significantly better metabolic control than did those with lower values. Anti-insulin antibodies were measured in 37 patients. There was no correlation between metabolic control and the affinity constants or binding capacities of these antibodies.

Iatrogenic inferior rectus palsy.

We examined two patients who developed unilateral inferior rectus muscle palsy following inferior oblique myectomy. Surgical exploration showed a normal inferior rectus muscle and tendon in both patients. Surgical correction consisted of inferior rectus resection in one patient and inferior rectus resection combined with an ipsilateral superior rectus recession in the other. We propose inadvertent excision of the lateral portion of the inferior rectus muscle during inferior oblique myectomy as the probable mechanism of inferior rectus injury.
