    Author: Bashir G, Shah A, Thokar MA, Rashid S, Shakeel S.

    Abstract:
    Corneal ulceration continues to be one of the most important causes of ocular morbidity and blindness worldwide. Between April 1999 and May 2001, 80 patients with corneal ulceration were examined to find the causative microorganisms, the sensitivity pattern of bacterial isolates to antibiotics, the predisposing factorsfor ulcerative keratitis and the comparison between culture and gram staining results. Corneal ulceration was seen more in males than females, predominantly in farmers (61.25%) and trauma was the commonest predisposing factor, the agents being mainly organic agricultural materials. Of the 80 corneal ulcers, 32(40%) yielded pure bacterial growth while fungal growth was seen in 10(12.5%). Streptococcus pneumoniae was the commonest bacterium while Aspergillus fumigatus and Fusarium species were the commonest fungi isolated. Most of the bacterial isolates were sensitive to chloramphenicol and tetracycline followed by the quinolones. The overall sensitivity and specificity of Gram staining as compared to culture was 57.14% and 94.7% respectively.
