patients of them shOWedvisual acuity of less than 3/60 with best com:ction and
considered to be clinically blind .
For every case full personal history and full ophthalmological e’.”mination
were done. Statistical analysis of the collected data was done to determime the
significance of the different findings.
Of the 420 blind cases ,females represented 58.6% while males represented
41.4% .
The total prevalence rate of blindness in this study was 4.2% Rural
attendants shOWedmore prevalence of blindness than urban attendant~;
Rural -+ 68.6 %
Urban -7 31.4%
Prevalence of blindness was found to increase with age up to 60 years when
