[The specialist contribution--cataract]

The degenerative processes of the lens, combined with the deficiency lacrimal secretion syndrome duct to the old age and high sensitivity, often need the use of drops containing potassium and iodum, drops Known as anticataractogen drugs. Independent of the patient psychological balance status the decrease of visual acuity caused by the decrease of visual acuity caused by the senile cataracts, could be late with a time factor of 1.8-2.5 studied on a selected group of patients. We can conclusion that some forms of senile cataracts are associated with the deficiency of lacrimal substances which are essential in the lens metabolism. With the progression of time there isn't important improvement neither in congenital cataract nor in the traumatic cataract which progresses fast to opacification caused by direct or indirect lesion of the lens. The patients presenting senile cataracts at incipient stage or advanced are good responsive at the anticataractogen drugs. For a therapeutic successful is important to begin the treatment as early is possible, and to do this with regularity.
