| Ocular Infection / Condition | Microbial Pathogen / Causative Agent | Clinical Symptoms in Humans | Medical Urgency & First Aid Treatment |
|---|---|---|---|

- Copious Saline Flush: Lean over a sink and flush the affected eye with sterile eyewash solution or lukewarm running tap water for 2 to 3 minutes.
- Wash Hands with Antibacterial Soap: Scrub hands thoroughly for 20 seconds before touching your face again.
- Remove Contact Lenses: Discard disposable soft contact lenses immediately to prevent bacterial biofilm trapping.
