[Irvine-Gass syndrome. Statistical and angiographic study].

This study is based on a detailed investigation of 12 cases of Irvine-Gass syndrome which was observed during the examination of 350 patients operated for pathological or senile cataract. The authors have found that: Males were affected more than females. Arteriol hypertension increases the frequency of the disease. The syndrome was found at an increase frequency in cases of nuclear cataract and in case where cataract was extracted by cryo-extraction. The bulge of the vitreous within the anterior chamber (without rupture of the anterior hyaloid membrane) causes a higher frequency of the disease. A similar observation was made when there was an incarceration of the vitreous to the surgical wound. The retreat of the edema was faster when the syndrome appeared earlier than the cataract operation. Whereas the restoration of good visual acuity did not depend upon the time of appearance of the disease. During the fluorescein study the following was observed. The possible participation of the chorio-capillaris layer in the pathogenicity of the disease. The diffusion of the fluorescein diminished with the improvement of the disease. Fluorescein angiography is unquestionably superior to simple ophthalmoscopy or the coloured photograph of the fundus of the eye, because the full extent of the existing damage can be revealed only through this method.
