RESUMO
A review of 135 consecutive cataract operations identified ten cases (7.4%) of operating microscope light retinopathy. Ophthalmoscopically, these light retinopathy lesions appeared as a focal pigment epithelial change with varying degrees of pigment clumping in the center. Fluorescein angiography accentuated the lesion by demonstrating a sharply demarcated transmission defect, occasionally with multiple satellite lesions. The shape of the lesion matched the shape of the illuminating source of the particular operating microscope used during the surgery. The most significant risk factor associated with the production of these light retinopathy lesions was prolonged operating time. Mean total operating time for the ten patients with light retinopathy was 51 minutes longer than for those without (P less than .0001). Other significant associated factors were the presence of diabetes mellitus (P less than .03), younger age (P less than .05), and the use of hydrochlorothiazide (P less than .04).

Between November, 1971, and July, 1975, 688 patients ranging in age from six hours to 21 years have undergone percutaneous transfemoral venous and/or arterial catheterization at the University of Oregon Health Sciences Center. This represents 93% of all venous catheterizations of the right side of the heart and 97% of all arterial catheterizations of the left side of the heart in the pediatric age range. One hundred and ninety-five patients (29% of the group) weighed 5 kg or less and 133 (20% of the group) were neonates. There were virtually no complications following the venous studies. The complication rate following percutaneous arterial studies is lower than is the reported experience with cut-down arteriotomies. Long-term survival following percutaneous atrial balloon septostomy in D-transposition of the great arteries was comparable to that following cut-down balloon septostomy. The ease of accomplishment, significantly lower complication rate, and successful accomplishment of atrial balloon septostomy prompt us to advocate that the percutaneous technique of cardiac catheterization be extended to include the neonate and young infant who weighsless than 5 kg.
