Abstract :

<p>&lt;p&gt;&amp;lt;p&amp;gt;&amp;amp;lt;p&amp;amp;gt;&amp;amp;amp;nbsp;Refractive errors are becoming more of a problem in many societies, with prevalence rates of myopia in many Asian&amp;amp;amp;nbsp;&amp;amp;lt;/p&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;countries reaching epidemic proportions. To determine the prevalence of refractive errors among medical students of&amp;amp;amp;nbsp;&amp;amp;lt;/div&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;kadapa. The present cross&amp;amp;amp;ndash;sectional descriptive study was conducted among medical students for a period of 6 months&amp;amp;amp;nbsp;&amp;amp;lt;/div&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;and 100 medical students were included. Those students having eyestrain and defective vision were subjected to auto refraction using Canon&amp;amp;amp;nbsp;&amp;amp;lt;/div&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;auto refractometer. Average of 3 readings were taken and confirmed by subjective verification. Chi&amp;amp;amp;ndash;square test with continuity correction, Z&amp;amp;amp;ndash;test&amp;amp;amp;nbsp;&amp;amp;lt;/div&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;for standard error of difference between 2 proportions and Fischer&amp;amp;amp;rsquo;s exact probability test (done manually assisted by Epi&amp;amp;amp;ndash;info package) were&amp;amp;amp;nbsp;&amp;amp;lt;/div&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;used. The prevalence of refractive errors was 32.24 %. Myopia (87.6%) was the most common refractive error with prevalence of 28.23 %.The&amp;amp;amp;nbsp;&amp;amp;lt;/div&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;occurrence of myopia was found high (28.23%) in medical students and the higher proportion were found among female students than male&amp;amp;amp;nbsp;&amp;amp;lt;/div&amp;amp;gt; &amp;amp;lt;div&amp;amp;gt;students&amp;amp;lt;/div&amp;amp;gt;&amp;lt;/p&amp;gt;&lt;/p&gt;</p>
