Estudo comparativo entre extensäo da aterosclerose coronária com os fatores de risco e as alteraçöes na artéria da retina / Comparative study of the extension of coronary arteriosclerosis with risk factors and changes in the retinal artery

PURPOSE--To identify a possible relationship of the extent of coronary artery disease, with risk factors for coronary artery disease and the retinal arteriolar changes (evaluated by fundoscopic examination). METHODS--We studied 96 patients (66 males), 36 to 72 years of age. All patients were studied by selective cinecoronaryarteriography, fundoscopic examination, as well as evaluated for the common risk factors, cigarette smoking diabetes, dislipidemia, systemic hypertension, age, alcoholism, male sex, family history and obesity. RESULTS--Male (p < 0.001) and smoking (p < 0.01) were the statistically significant associations with the extent of coronary artery disease. No significant relationship with the extent of coronary artery disease was present for the other risk factor nor for changes in retinal arteriolar branches. CONCLUSION--A relationship between extent of coronary artery disease with male sex and a cigarette smoker is occurred. No relationship with other risk factors, nor with retinal arteriolar changes were present

Conduta nas lesöes predisponentes ao descolamento de retina / Conduct of predispostions lesions for retinal detachment

A periferia retiniana é uma área avascular e na qual se insere a base do vítreo. Por essa razäo esta área costuma apresentar diversos processos degenerativos que se constituem em fatores predisponentes ao descolamento da retina. O autor discute as diferentes lesöes troficas, tracionais e mistas e indica a necessidade de tratamento profilático nas lesöes de maior risco. A fotocoagulaçäo é um procedimento pouco iatrogênico e sua indicaçäo pode ser feita nos casos de risco de rupturas e de descolamento
