Red rounded mass at your cat's inner eye corner (near the nose)? Could be cherry eye — the third eyelid gland prolapse. Upload a close-up photo — AI identifies healthy normal eye vs mild cherry eye vs classic cherry eye vs severe inflamed cherry eye vs conjunctivitis swelling lookalike. Urgency assessment plus typical US vet cost estimate. ⚠️ Severe inflamed mass or cat rubbing eye constantly = vet within 48h — skip the photo and go.

Gently hold your cat's head still and take a close-up of the inner corner of the eye (near the nose) where cherry eye appears. Capture both eyes if possible for left-vs-right comparison. Focus on the inner corner — that's where the third eyelid sits. Natural daylight, no flash.
The AI compares your photo against 5 distinct cat inner-eye corner patterns: healthy normal eye (no protrusion), mild cherry eye (small early protrusion of third eyelid gland), classic cherry eye (prominent red rounded mass), severe inflamed cherry eye (dry exposed mass + surrounding eye redness), and conjunctivitis swelling lookalike (red puffy eyelid but no rounded mass at the corner).
Receive likely sub-type identification (healthy / mild cherry eye / classic cherry eye / severe inflamed cherry eye / conjunctivitis lookalike), urgency level (watch at home → vet within 48h), typical US vet visit cost estimate, and what to prepare. AI is educational pattern recognition — not a veterinary diagnosis. Cherry eye almost always needs a vet repair procedure.
Cherry eye in cats — match what you see at your cat's inner eye corner to the most likely sub-type. Upload your cat's eye photo above for AI analysis that goes deeper than this table.
Clean smooth inner eye corner + no rounded protrusion + cat blinking normally
Healthy normal cat eye — no action needed, this is the baseline pattern
Small pink-red rounded bump just appearing at inner corner + eye still bright + no redness
Mild cherry eye in cats — early stage, vet appointment to assess if it self-resolves or needs repair
Prominent red rounded mass covering the inner eye corner + eye still moist + cat not squinting
Classic cherry eye — vet repair procedure usually needed within 1-2 weeks before mass dries
Large red mass + dry-looking exposed surface + surrounding eye redness + cat rubbing the eye
Severe inflamed cherry eye — vet visit within 48 hours to repair before infection or corneal damage
Entire eyelid red and puffy + watery discharge + NO rounded mass at the corner
Conjunctivitis swelling (not cherry eye) — different cause, vet visit for eye infection workup
