Purpose. To report an unusual case of severe bilateral fungal keratitis following laser in situ keratomileusis (LASIK). Method. A 48-year-old man developed bilateral diffuse corneal infiltration two weeks after LASIK. The corneal scrapings revealed fungal filaments but cultures were negative. Results. The corneal ulceration was improved on the left eye whereas spontaneous perforation occurred a...

Acanthamoeba keratitis is a type of protozoa keratitis caused by free-living fresh water Amoeba. It recently gains importance because of increasing incidence, difficulty in diagnosis and unsatisfactory treatment. It is seen more commonly in contact lens wear using homemade saline or may be in non-contact lens wearers due to swimming or bathing in contaminated water. This infection is commonly c...

OBJECTIVE To estimate how a corneal isolate's minimal inhibitory concentration for a fluoroquinolone agent affects the rate of clinical response of bacterial keratitis to fluoroquinolone therapy. DESIGN Prospective cohort study. METHODS Six hundred sixty-three individuals with suspected bacterial keratitis underwent diagnostic corneal scraping and were treated with topical 0.3% ciprofloxaci...

BACKGROUND Corneal ulcer is an important cause of blindness in developing countries. Therapeutic keratoplasty for infective keratitis is a frequently performed surgery in these countries. OBJECTIVE To find out the outcome of therapeutic keratoplasty for infective keratitis. METHODS Records of 5 years were reviewed of patients who underwent therapeutic keratoplasty from 2006 to 2010. Data co...

We read with interest the recent article by Tendolkar et al. (5). We have been seeing and treating cases of Nocardia keratitis for a long time and have published our experiences previously (3, 4). We would like to share some of our observations on this condition for the benefit of JCM’s readers. Nocardia keratitis can occur in immunocompetent patients following minor trauma (3). While lagophtha...

BACKGROUND A multicentre study was carried out in Ghana and southern India to determine the aetiology of suppurative keratitis in two regions located at similar tropical latitudes. Studies of fungal keratitis from the literature were reviewed. METHODS Patients presenting at rural and urban eye units with suspected microbial keratitis were recruited to the study. Corneal ulceration was defined...

IMPORTANCE Scarring from bacterial keratitis remains a leading cause of visual loss. OBJECTIVE To determine whether topical corticosteroids are beneficial as an adjunctive therapy for bacterial keratitis if given early in the course of infection. DESIGN, SETTING, AND PARTICIPANTS The Steroids for Corneal Ulcers Trial (SCUT) was a randomized, double-masked, placebo-controlled trial that over...

PURPOSE Bacterial keratitis is an ocular infection with the potential to cause significant visual impairment. Increasing patterns of antibiotic resistance have necessitated the development of new antimicrobial agents for use in bacterial keratitis and other serious ocular infections. With a view to exploring the use of novel antimicrobial peptides in the management of ocular infection, we perfo...

Purpose To investigate the effectiveness of antimicrobial blue light (aBL) as an alternative or adjunctive therapeutic for infectious keratitis. Methods We developed an ex vivo rabbit model and an in vivo mouse model of infectious keratitis. A bioluminescent strain of Pseudomonas aeruginosa was used as the causative pathogen, allowing noninvasive monitoring of the extent of infection in real ...

Although rarely performed, corneal biopsy may be useful in establishing the diagnosis and prompt institution of appropriate management in progressive keratitis of unknown cause. Inability to obtain a definitive diagnosis in a case of chronic keratitis may be related to previous use of antimicrobials that interfere with standard cultures or by the fastidious growth of unusual pathogens in cultur...
