Dear Editor,

This refers to a well-drafted article by Nath et al., published in a recent issue of the Indian Journal of Ophthalmology. [1] We would like to draw attention to a few points. In the presented study, the authors found the presence of fungal elements by 10% KOH smear in only 65.2% cases, which is quite less than our practical experience and from the results of other studies.

Sharma et al., [2] found fungal filaments in 100% and 81.2% of the corneal scrapings by the KOH method in the two phases of their study, while Gopinathan et al., [3] found it to be 91% in their study. In most of the private practitioners and smaller centers where culture facilities are not available, KOH smear is the only reliable and easy-to-use diagnostic tool, and it works in 90-95% of the cases.

Secondly, the treatment of perforated fungal ulcers needs to be separated from the ulcers without perforations, as the eye can sometimes be saved only by therapeutic keratoplasty, [4] although in smaller perforations cyanoacrylate glue also works very well. [5]
