Ocular trauma and contact lens (CL) wear are leading causes of microbial keratitis in young adults. Treatment incurs significant healthcare costs and can lead to vision loss.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Public Health

Background:

  • Microbial keratitis is a significant cause of vision loss.
  • Identifying predisposing factors is crucial for prevention and management.
  • Understanding treatment costs and visual outcomes informs healthcare resource allocation.

Purpose of the Study:

  • To investigate the primary risk factors contributing to microbial keratitis.
  • To analyze the financial costs associated with treating microbial keratitis.
  • To evaluate the visual outcomes following treatment for microbial keratitis.

Main Methods:

  • Retrospective review of medical records for 291 patients with microbial keratitis.
  • Data collected included demographic, clinical, and microbiological information.

  • Analysis focused on predisposing factors, treatment costs, hospital resource use, and vision loss.

    • Main Results:

    • Ocular trauma (36.4%) and contact lens (CL) wear (33.7%) were the most frequent predisposing factors.
    • CL wear was associated with younger patients and a higher incidence of Gram-negative organisms.
    • Acanthamoeba keratitis was the most expensive to treat, and 21.7% of patients experienced significant vision loss.

    Conclusions:

    • Ocular trauma and CL wear are primary drivers of microbial keratitis in the studied population.
    • Microbial keratitis necessitates substantial healthcare resources and poses a risk of permanent vision impairment.
    • Further research into preventative strategies for these high-risk groups is warranted.
