Medical Details

Transmission

Viral and bacterial conjunctivitis are highly contagious. Allergies are not. Determining the cause is key to understanding risk.

Progression & Stages

Signs include redness, swelling, and discharge (clear, mucus, or pus). If untreated, infection can spread to the cornea causing ulcers.

Diagnosis

Fluorescein stain rules out ulcers. Schirmer Tear Test rules out Dry Eye. Cytology may identify bacteria vs inflammatory cells.

Treatment Protocols

Topical antibiotic ointments (like Terramycin) are standard. Viral cases in cats may need antivirals. Allergic cases need steroid drops (ONLY if no ulcer is present).

Prevention

Vaccines reduce severity of feline viral causes. hygiene helps prevent spread.

Prognosis

Excellent with treatment. Chronic viral cases in cats may have flare-ups during stress.
