Abstract: :
Purpose: To demonstrate the importance of the ocular ultrasound scan (E) as a diagnostic and prognostic method before cataract surgery (CS), in order to identify posterior segment abnormalities not detected by clinical examination. The E is an effective diagnostic method and provides analysis of the subsequent segment, besides being innocuous to the patient. It is a procedure that allows the identification of abnormal findings in the posterior segment such as tumors, opacification of the transparent structures, retinal and/or choroidal detachment, foreign bodies and other rare conditions. This is an easy and low cost method. Methods: E was performed in 200 eyes of 200 patients in which the fundus eye examination was impracticable before CS. After the verification of the cataract and of the surgical indication the ultrasound scan A and B, besides the ecobiometry were accomplished. The patients were submitted to extracapsular extraction of the crystalline by the residents of the Goiania Eye Institute, always followed by a specialist. One week after surgery all the patients were submitted to binocular indirect ophthalmoscopy (BIO). Results: E findings were: 44% of the eyes had no pathologic conditions; 24%, vitreous alterations; 23,5%, vitreous detachment; 4%, retinal detachment; 2%, focal retinal atrophy; 2%, suggesting increased papilla excavation and 0,5%, coriorretinal thickness increase. After CS, BIO confirmed most of the alterations diagnosed by E. Conclusions: E is an indispensable method in preoperative examinations for cataract surgery for it is an easy, cheap and reliable exam to identify possible alterations not visualized by ophthalmoscopy, improving surgical prognosis.
