keratitis
Let an agent explain keratitis in general terms, relay causes, types, risk factors, prevention and treatment approaches from ophthalmology sources, route symptoms to urgent eye care, describe the named forms, and distinguish keratitis from conjunctivitis, uveitis, dry eye disease and corneal abrasion, without diagnosing individuals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain keratitis in general terms, relay causes, types, risk factors, prevention and treatment approaches from ophthalmology sources, route symptoms to urgent eye care, describe the named forms, and distinguish keratitis from conjunctivitis, uveitis, dry eye disease and corneal abrasion, without diagnosing individuals.
Inflammation of the cornea, the clear front surface of the eye, caused by infection with bacteria, viruses such as herpes simplex, fungi or Acanthamoeba, often linked to contact lens misuse, or by injury, dry eye or ultraviolet exposure as in photokeratitis, also called snow blindness or welder s flash; forms the registry aliases name include corneal ulcers, superficial and filamentary keratitis, macular keratitis and corneal neovascularisation as a complication. Keratitis can threaten vision, and eye pain, redness, light sensitivity or blurred vision, especially in contact lens wearers, need urgent eye care, while contact lenses should not be worn while swimming or sleeping unless designed for it.
What it is for: Not applicable; an eye condition.
It can be explain causes and types; relay prevention and contact lens hygiene; describe named forms; route symptoms urgently.
Distinguishing features
Corneal inflammation
Vision-threatening
Contact lens link
Infectious and non-infectious
What it looks like
A red painful eye, sometimes with a white or grey spot on the cornea.
Physical character
Acanthamoeba risk: linked to water exposure with contact lenses note
photokeratitis onset: hours after UV exposure note
herpes simplex keratitis: leading infectious cause of corneal blindness in some regions note - attributed
How it is recognised
Inflammation of the cornea
Corneal ulcer, photophthalmia, corneal neovascularisation, macular keratitis, superficial keratitis, filamentary keratitis
Conjunctivitis affects the conjunctiva; uveitis affects inner eye layers; dry eye disease is tear film dysfunction; corneal abrasion is a scratch
