The incidence of fungal keratitis is less common than bacterial and viral keratitis. However, it remains a diagnostic and therapeutic challenge. Delayed clinical diagnosis is common mainly because of lack of suspicion. Further slow growth of fungus increases the time for confirmed laboratory diagnosis. After accurate diagnosis, patient's management remains inadequate due to lack of availability of antifungal agents and its poor corneal penetration. Multitude of genera of molds and yeast have been identified in fungal keratitis. Due to their ubiquitous nature and easy isolation from the environment, their role in true pathogenesis is difficult to ascertain. Worldwide, incidence of fungal keratitis is rising at present. The predisposing factors comprises trauma, use of contact lenses and topical steroids. Filamentous fungi and dematiaceous fungi are the frequently encountered etiological agents of fungal keratitis. Dimorphic fungi are reported less frequently. Fungal keratitis tends to occur more frequently in young males and usually in winter and monsoon. Penicillium genera includes several species. By far Penicillium marneffei (P. marneffei) infection is most common, mainly associated with AIDS. A number of infections caused by species other than P. marneffei have been reported as well. Here we report a case of Penicillium keratitis in a young, HIV negative male farmer.

Purpose: The primary objective was to evaluate the clinical response of refractory cases of fungal keratitis to topical 1% posaconazole therapy.
Methods: Prospective longitudinal non-randomized open label dual-cohort study of 70 eyes of refractory fungal keratitis, 35 were recruited as posaconazole treatment (PCZ) group for topical 1% posaconazole therapy and compared to 35 eyes on conventional antifungal therapy. Study parameters included demographic and treatment details, visual acuity, comprehensive slit-lamp biomicroscopy, clinical photography, ASOCT at recruitment and weekly (week 1, 2, 3 and 4 after treatment initiation).

Background: Infectious keratitis (IK) is a blinding disease and an important cause of ocular morbidity. Understanding regional trends in IK are important to understand the epidemiology and clinical outcomes of this disease.
Methods: In this 10-year retrospective review, patient characteristics including sociodemographic factors, medical history, and ocular history were collected as well as the clinical course and outcomes.

A male patient in his 20s, suffering from a persistent, infection-related corneal endothelial plaque (EP) was urgently referred to our tertiary medical centre for therapeutic penetrating keratoplasty (TPK). Over the preceding month, he had been undergoing treatment with both topical and oral antifungal medications due to clinical suspicion of fungal keratitis. At our centre, an endothelial scraping was performed using a reverse Sinskey hook to obtain samples for microbiology and revealed septate branching fungal hyphae.
