...Doctors who gave up using ACTH for some common eye diseases quit too soon, two Michigan researchers told the Association of American Physicians. For inflammation of the optic nerve, and also for degenerative diseases of the choroid and retina, ACTH can be given for a year or two, may then restore 20-20 vision to patients who have been almost blind...
Mayor Lawrence's trouble was a condition known as "detached retina." A section of the retina (the eye's inner nerve coat) is torn loose from the choroid (the spongy surrounding membrane that normally supplies the retina's nourishment). The space between the retina and choroid fills up with fluid, gradually enlarging the break. As the undernourished retina deteriorates, the patient's vision blurs, eventually fails...
...welding" operation, now widely used, has been successful in many cases. The surgeon, after turning the eyeball around, first punctures it in several places to drain the fluid between retina and choroid. Then he seals the two membranes together by heating them. The inflamed, swollen retina and choroid close up like inflated inner and outer tubes and eventually heal tightly together...
Purpose of Dr. Scarff's operation on Alice was to destroy the choroid plexus in her first two ventricles, thus diminishing the water supply to her brain. (The third and fourth ventricles are smaller, produce minute quantities of water.) First he made a one-inch slit on the top of her scalp, cut out a small plug of bone. Into the tiny hole he inserted his ventriculoscope...
...brain, and an electric wire for cauterizing. At the top of the instrument is an eye piece and an electric connection. Gently working the ventriculoscope through Alice's grey matter down to one of her ventricles, Dr. Scarff was able to see about two inches of choroid plexus. Turning on the electricity, he seared off all the feathery tissue he could reach with his hot wire. Within a half hour he had cauterized the choroid plexus in both ventricles. After the operation, he gently withdrew the tube, inserted the plug of bone, neatly stitched up the baby...
