ABSTRACT

Objective To evaluate the treatment effect of using the double frequency Laser 532 to treat the pathological changes of retina due to diabetes before proliferation. Methods To condense the rays of the wavelength 532nm green laser on the pathologically changed retina and the case-pattern rays on the yellow spot,the full ray-condensed retina should be dealt with after the ray condensation of the yellow spot. During the following 8 months, close attention should be paid to the improvement of the pathologically changed retina, the fadeaway of the dropsy of the yellow spot and the change of eyesight after the operation. Results 67 of 86 persons were improved in their eyesight, with the percentage of 78. 5% ,17 persons(19.5% ) didn't improve and only 2 (2 %) were worse. Conclusion The double frequency laser 532 is effective in treating the pathologically changed retina due to diabetes before proliferation, and has obvious effect in improving the eyesight of the persons with the limited yellow-spot dropsy through the ray condensation.
