Show In the field of contact glasses and telescopic spectacles, great progress has been made, and the dream of Sir William Herschel of supplanting an irregular and imperfect im-perfect cornea by a glass lens has been realized. As a consequence, thousands of individuals have been enabled to carry on their work as breadwinners, free from charity or dependence on their families. Formerly, in detached retina cases which underwent surgical attention, approximately 1 per cent recovered. Today, due to different dif-ferent technique, fully '50 per cent of such cases retain their vision. Cross-eyed persons have benefited materially as a result of the vast work done by surgeons in this line, and it is a generally accepted belief among experts that another ten years' work will enable en-able specialists to guarantee such patients a hundred per cent of recovery re-covery in all such operations. In addition, the neurologists and the brain surgeons have done masterful work in the prevention of blindness, by recognizing early and promptly treating conditions which would ultimately mean total blindness. "Today instead of phalanx pha-lanx after phalanx marching toward to-ward inevitable darkness," says Dr. L. H. Hardy, "there is more chance than ever before of these unfortunate ones either retaining or improving their vision." THE DOCTOR WEAUCHJNMUGHMJX ! Eye Diseases . . . n is positively difficult for the average layman to appreciate the wonderful advance made in recent years in the treatment of various diseases of the eye, which have re- I suited in the preservation or res- ! toration of vision Of course, there is much more to be done, but the trail blazed by von Helmholtz, von Graefe and other scientists is rapidly being extended by others and it is difficult to predict just what to expect next. To cover so vast a field would require volumes, vol-umes, while I, of necessity, must 5 be brief. Thousands of children confront- ''ed with a condition which means death or a life of blindness, have had their eyes salvaged by radon seeds and gamma ray radiation. The restoration of sight by the transplantation of tissue has given other thousands a clear view of the outside world. Parts of the cornea have been transplanted from a dead eye to a living human hu-man being who would have stum- 1 bled through life blind. |
