Comparision of 2 types of optometry methods after the pupils of far-sighted sufferers were dilated

Objective: To observe whether there exists difference in the test results of far-sighted ametropia sufferers' eyesight by computer optometry instruments and by streak retinoscope respetively after their pupils were dilated,and to know if the retinoscopy optometry can be replaced by computer optometry.Methods: Twenty-five far-sighted ametropia sufferers who had accepted optometry in 1996 in our hospital were selected at random.After their pulils were dilated,the computer optometry instrument and streak retinoscope were adopted respectively to test the ametropia degree;then the statistical data were analyzed.Results: Examination results by the two methods were significantly different(P<0.01).Conclusions: The test results by computer optometry is not exact.It denotes that the retinoscopy optometry can still not be replaced by computer optometry;as the latter is simple,easy and fast in operation,it can be used as a reference for the former,and applied in popular examination as well.
