🔍 What Is Anterior Uveitis?

Anterior uveitis refers to inflammation affecting the iris and ciliary body—part of the uveal tract—often called iridocyclitis or iritis. This painful condition compromises vision and can quickly progress to serious complications if not treated :contentReference[oaicite:3]{index=3}.

1. Who Is Affected?

• Any age—but older cats with systemic disease (FeLV, FIV, FIP, toxoplasmosis) are more susceptible :contentReference[oaicite:4]{index=4}.
• Both genders, often unilateral when due to trauma or neoplasia, bilateral in systemic causes :contentReference[oaicite:5]{index=5}.
• Underlying lens issues (cataract, lens luxation) or prior surgery/trauma may predispose :contentReference[oaicite:6]{index=6}.

2. Recognizing the Signs

• Squinting, blepharospasm, light sensitivity :contentReference[oaicite:7]{index=7}.
• Redness (episcleral hyperemia), cloudy iris, aqueous flare, fibrin or hypopyon visible :contentReference[oaicite:8]{index=8}.
• Miosis, irregular pupil shape, reduced intraocular pressure initially :contentReference[oaicite:9]{index=9}.
• Excessive tearing, third eyelid protrusion, possible vision loss :contentReference[oaicite:10]{index=10}.

3. Underlying Causes

a. Ocular

• Trauma, corneal ulcers, lens-induced inflammation :contentReference[oaicite:11]{index=11}.
• Intraocular tumors or melanoma, lymphosarcoma :contentReference[oaicite:12]{index=12}.

b. Systemic

• Viral: FeLV, FIV, FIP :contentReference[oaicite:13]{index=13}.
• Protozoal: toxoplasmosis; parasitic like leishmania :contentReference[oaicite:14]{index=14}.
• Fungal or bacterial infections :contentReference[oaicite:15]{index=15}.
• Immune-mediated or metabolic disease like diabetes :contentReference[oaicite:16]{index=16}.

4. Diagnostic Work-Up

1. Ophthalmic exam: slit lamp or direct ophthalmoscope to assess flare and cell count :contentReference[oaicite:17]{index=17}.
2. Fluorescein staining: to rule out corneal ulcers :contentReference[oaicite:18]{index=18}.
3. Tonometry: measure IOP to identify glaucoma (risk increases) :contentReference[oaicite:19]{index=19}.
4. Bloodwork & urinalysis: test for FeLV, FIV, FIP, toxoplasma, diabetes, etc. :contentReference[oaicite:20]{index=20}.
5. Imaging: ocular ultrasound or radiographs for masses/shunts :contentReference[oaicite:21]{index=21}.
6. Intraocular sampling: aqueous tap for cytology/culture when infection or neoplasia suspected :contentReference[oaicite:22]{index=22}.

5. Treatment Protocol

Aggressive therapy early is essential to prevent complications such as glaucoma, cataracts, synechiae, or retinal detachment :contentReference[oaicite:23]{index=23}.

a. Topical Anti‑inflammatories

• Prednisolone acetate 1% or dexamethasone 0.1% drops—steroid of choice :contentReference[oaicite:24]{index=24}.
• NSAID drops (e.g., flurbiprofen) if steroids contraindicated :contentReference[oaicite:25]{index=25}.

b. Cycloplegics/My­driatics

• Atropine or homatropine—relieves pain, prevents iris synechia :contentReference[oaicite:26]{index=26}.

c. Systemic Therapy

• Oral NSAIDs (meloxicam) or steroids—if bilateral or severe :contentReference[oaicite:27]{index=27}.
• Targeted antimicrobials for infection, antifungals or antivirals as needed :contentReference[oaicite:28]{index=28}.

d. Underlying Cause

• Treat systemic disease—FeLV/FIV management, toxoplasmosis, cancer therapy.
• Address ocular disease—mass excision, trauma repair, cataract management.

6. Supportive & Monitoring Care

• Frequent rechecks—initially daily until inflammation controlled :contentReference[oaicite:29]{index=29}.
• Monitor IOP—watch for steroid-induced glaucoma :contentReference[oaicite:30]{index=30}.
• Adjust frequency of drops over weeks to months based on response.
• Consider referral to ophthalmologist when response is slow or cause unclear.

7. Complications & Prognosis

• Possible complications: glaucoma, cataracts, retinal detachment, lens luxation :contentReference[oaicite:31]{index=31}.
• Prognosis depends on cause; idiopathic/infectious often good; neoplastic or chronic cases may require long-term management or surgery (enucleation) :contentReference[oaicite:32]{index=32}.

8. Ask A Vet Remote Monitoring 🐾📲

• 📸 Upload photos/video of the affected eye—redness, discharge, pupil size for vet evaluation.
• 🔔 Medication reminders—eye drops and systemic therapy scheduling.
• 🧭 Track comfort, vision changes, pupillary response, light avoidance behaviors.
• 📊 Alerts for potential complications—cloudiness, blistering, no pupil dilation.
• 👥 Virtual consults to adapt therapies, schedule diagnostics, or plan in-person ophthalmology referral.

9. FAQs

Can uveitis cause blindness?

Yes—if untreated, inflammation may lead to glaucoma, cataracts, or retinal damage :contentReference[oaicite:33]{index=33}.

Is steroid use dangerous?

Safe when used under vet guidance; regular tonometry is essential to prevent steroid-induced glaucoma :contentReference[oaicite:34]{index=34}.

How long will treatment last?

Typically weeks to months depending on cause; ocular symptoms subside within days but prevention of recurrence requires adherence :contentReference[oaicite:35]{index=35}.

Can it recur?

Yes—especially with underlying disease like FIP, lymphoma, or lens issues. Long-term monitoring is essential.

10. Take‑Home Tips ✅

• Recognize early signs: squinting, red eye, pain.
• Diagnose fully: tonometry, stains, bloodwork, imaging.
• Treat aggressively: topical steroids + cycloplegics early.
• Manage cause: infection, cancer, trauma—holistic therapy.
• Monitor closely: rechecks and IOP to avoid complications.
• Use Ask A Vet: for remote follow-up, medication support, and condition tracking.
