Graves' disease with ophthalmopathy following radiotherapy for Hodgkin's disease.

The number of patients achieving long-term survival following neck irradiation for Hodgkin's disease and other malignancies is increasing. Paralleling this increase in survivors is the development of late complications of the therapy itself. Eleven patients have previously been reported who developed Graves' ophthalmopathy 18 months to seven years after receiving neck radiotherapy for nonthyroidal malignancies. The seven patients who had HLA typing were all HLA-B8 negative, despite the reported association of the HLA-B8 antigen with Graves' disease. A patient who is HLA-B8 positive who developed Graves' ophthalmopathy and hyperthyroidism nine years after receiving mantle radiotherapy for Hodgkin's disease is reported. It is recommended that Graves' disease be included among the thyroid diseases that receive consideration during follow-up of patients who have received mantle radiotherapy.

Iris angiography and aqueous photofluorometry in normal subjects.

Iris angiography and photofluorometry of the aqueous were performed on 44 normal subjects equally distributed between 15 and 65 years of age. Hemoglobin AIc determinations were performed in 20 of these persons. Leakage from the pupillary margin was present in 20% of the eyes studied. In all cases of leakage, the dye faded quickly after the initial peak concentration. No leakage was observed from radial iris vessels. Photofluorometric readings of the aqueous 60 minutes after injection increased significantly with age. Hemoglobin AIc measurements were observed to correlate significantly with aqueous fluorescein concentration. Both these observations may reflect an altered permeability of biologic membranes associated with aging.

The treatment of angle neovascularization with panretinal photocoagulation.

Thirty-two eyes in 28 patients with anterior chamber angle neovascularization were prospectively treated with panretinal photocoagulation. Of 17 eyes that had less than 270 degrees angle closure, with an intraocular pressure of less than 40 mm Hg prior to treatment, 16 showed complete disappearance of the angle neovascularization and stabilization of the peripheral anterior synechiae after treatment. None of the 15 patients who had angle closure of 270 degrees or greater, or an intraocular pressure of above 40 mm Hg, showed any significant improvement after treatment. These results suggest that panretinal photocoagulation offers a highly effective means of dealing with early and moderately advanced cases of angle neovascularization.

The effect of pan-retinal photo-coagulation on rubeosis iridis.

Fifteen eyes of 11 patients with rubeosis iridis and angle neovascularization associated with retinal vascular disorders were treated with pan-retinal photocoagulation. In seven of the 15 eyes, the new vessels on the surface of the iris and in the angle regressed after pan-retinal photocoagulation therapy for disk neovascularization; five of the remaining eight eyes that were treated prospectively demonstrated similar involution of the rubeosis iridis. In three of the five preexisting peripheral anterior synechiae regressed and angle structures previously obscured became visible. Three to 36 months after therapy, three eyes developed a few new abnormal iris and angle vessels.

Effect of dietary potassium percent for lactating dairy cows.

Three groups of Holstein cows (four cows per group) past the peak of lactation were fed dietary potassium as percent of dry matter as follows: .45% for 20 days to all groups; .45, .55, and .66% to the respective groups for 12 wk; and .66% to all groups for 19 days. Dietary potassium had no significant effect on milk fat and solids-not-fat contents of milk, milk production, or milk and blood serum cations (potassium, sodium, magnesium, calcium). However, body weights were affected. Symptoms common in potassium deficiency were not apparent. Average daily milk production, feed intake, and body weight gains for the 12 wk in kilograms were: 21.9, 15.8, and 15.7; 23.4, 16.4, and 54.5; and 22.8, 19.9, and 92.9 for the .45, .55, and .66% rations. When .66% potassium was fed to groups previously fed .45 and .55% potassium, feed intake increased by 3.6 kg and 1.3 kg but increased only .2 kg in the group previously fed .66%.
