AI Article Synopsis
- The study investigates the occurrence and demographics of Acanthamoeba keratitis at a cornea clinic in India over a six-year period.
- Approximately 4519 patients were screened, with 32 confirmed cases, predominantly affecting males, and most cases linked to corneal trauma from solid objects.
- The research finds a consistent monthly prevalence of Acanthamoeba keratitis, indicating a rising trend among non-contact lens users in the region.
Article Abstract
Purpose: This study analyses the prevalence, demography, predisposing factors and seasonal variation of Acanthamoeba keratitis.
Methods: A retrospective review of all cases presenting with keratitis at the cornea clinic, Aravind Eye Hospital, Coimbatore, from August 1997 to July 2003, was done for screening patients with a provisional diagnosis of Acanthamoeba keratitis. Their records were further analyzed for microbiological details. Cases with culture proven Acanthamoeba keratitis were included for epidemiological analysis.
Results: From a total of 4519 patients who attended cornea clinic 32 (33 eyes) patients were confirmed to be positive for Acanthamoeba keratitis. Twenty cases (62.5%) were males. Majority (18; 54.2%) of the Acanthamoeba keratitis eyes reported corneal trauma by solid objects. No peak period was observed in a year, as the number of cases was almost uniform in all months.
Conclusion: This study indicates the increasing prevalence of Acanthamoeba keratitis among non-contact lens users in this region during the 6-year period.

Purpose: This retrospective study aimed to investigate demographic characteristics, predisposing factors, and clinical outcomes in patients with parasitic keratitis.
Methods: Medical records of patients with molecularly confirmed Acanthamoeba or microsporidia, identified through corneal scraping specimens (collected between September 21, 2017, and June 27, 2023), were reviewed. Demographic data, clinical profiles, such as symptom duration before confirmed diagnosis, antiviral treatment pre-diagnosis, contact lens use, tap water and soil contamination, ocular trauma, and treatment regimens, were analyzed.
We present a case of mixed microbial keratitis in an otherwise healthy contact lens wearer. The microbes detected on microscopy included , , , and . and are well-recognised corneal pathogens, although is uncommon, and is extremely rare.

Introduction: Infectious keratitis is a rare but devastating complication following photorefractive keratectomy (PRK) that may lead to visual impairment. This study assessed the clinical features, treatment strategies, and outcomes of post-PRK infectious keratitis.
Methods: This retrospective study was conducted on patients with post-PRK infectious keratitis presenting to Khalili Hospital, Shiraz, Iran, from June 2011 to March 2024.
