Aim: To study the microbiological and epidemiological profile of patients with suppurative corneal ulcer presenting in a rural referral center situated in a Sub-Himalayan territory of north India. The study was conducted to evaluate the epidemiology and frequency of mycotic keratitis among the patients of suppurative corneal ulcer and to identify various fungal species as etiological agents. Methods: Corneal scrapings from 56 patients of suppurative corneal ulcers were subjected to direct microscopy and culture. Results: Of the 56 cases of suppurative corneal ulcer investigated, fungal etiology was identified in 18 (32%) cases. Most of the patients (82.1%) worked in agriculture. Trivial trauma with vegetative matter was the most common predisposing factor. Fusarium and Acremonium species were the most common fungi isolated, followed by Aspergillus. Four cases of rare mycotic keratitis caused by Paecilomyces lilacinus, Scedosporium apiospermum, Monilia sitophila, and Ulocladium species were detected. Four cases were smear positive (10% KOH wet mount) but culture negative. Analysis of KOH wet mount was done using culture as gold standard. The sensitivity and specificity of KOH wet mount was 71.43% and 90.48%, respectively. Conclusion: Direct microscopy and culture has a greater diagnostic value in the management of suppurative corneal ulcer. The authors have observed changes in the pattern of organisms identified as cause of fungal keratitis in the region. Rare species of fungi may also be detected if corneal scrapings are collected for direct microscopy and culture from all the cases of suppurative corneal ulcers greater than 2 mm.

Purpose. To evaluate the efficacy of a combination of intrastromal and intracameral injections of amphotericin B in the treatment of severe recalcitrant fungal keratitis.Methods. Patients with severe fungal keratitis who were resistant to conventional antifungal medical treatments and needed potential surgical intervention were recruited at the First Affiliated Hospital of Fujian Medical University between January 2012 and July 2013. The patients were treated with a combination of intrastromal and intracameral injections of amphotericin B (25 μg/mL and 50 μg/mL, resp.). Selectively repeated injections were performed as necessary. The efficacy, complications, and outcome were evaluated.Results. Nine patients (9 eyes) were involved in this study. All 9 cases responded favorably, and the clinical appearance of serious corneal damage and intraocular extension was resolved after the treatment. Four eyes required only 1 injection, and 5 eyes required repeated injections. Seven corneal ulcers healed with leucoma, and 2 healed with adherent leucoma. All of our cases had a marked increase in the anterior chamber reaction and pain immediately after the injection. There was no obvious clinical evidence of corneal or lenticular toxicity in any patient.Conclusions. A combination of intrastromal and intracameral injections of amphotericin B may be safe and effective for the treatment of severe fungal keratitis that is resistant to conventional therapy.

Corneal infections are one of the leading causes of ocular morbidity and blindness world-wide. If normal defence mechanisms of the eye are compromised, almost any microorganism can invade the cornea. It is important to know the exact aetiology of corneal ulcer to institute appropriate therapy in time, least serious consequences may follow.  To isolate and identify the fungi from corneal scrapings of suspected keratitis patients. A prospective study of Fungal keratitis was conducted at Al-Azhar Medical College & Super Speciality Hospital in Thodupuzha, Kerala a tertiary care hospital with a capacity of 650 beds. The duration of the study was two years from January 2018 to January 2020. Patients with suspected fungal corneal ulcers presenting in the Out-Patient Department (OPD) of Ophthalmology were investigated for fungal etiology in the Department of Microbiology were included in this study. Each patient was examined with slit lamp. Data collected from history given by patient and patient examination. Using standard techniques. The specimens collected were then smeared on two slides, which were stained with Gram stain (for bacterial keratitis) and 10% potassium hydroxide preparation (for fungal keratitis) studied under light microscope. Of the 866 patients with corneal ulcer investigated, 83 cases with fungal and 36 with bacterial aetiology was identified. Males were more commonly affected and were mostly in the age group of 31-40 year. It was seen that trauma was the most common predisposing factor especially in the agriculturists and the farmers. Among the identified fungi, most were hyaline. Of the 83 positive specimens, the most frequent agent isolated was Fusarium species in 31 (37.3%) cases. 23 (27.7%) was the second most common followed by , ., . Candida albicans were 5 (6%) followed by 1 (1.2%). Fungal Keratitis is a serious problem usually following corneal trauma, it requires rapid detection and identification of fugal agents for treatment to prevent disastrous consequences.
