Dog Corneal ulcer, explained like you are in school.

Hi Everyone! My name is Dan, and I am a veterinarian. Today and I going to explain how a veterinarian diagnosis a scratched eye and how that eye is treated. In this video I draw a scratched eye and how it is treated. A corneal ulcer in dogs is essentially an open sore on the cornea (the clear outer layer of the eye). It’s a common but potentially serious condition, since the cornea is very thin and can rupture if the ulcer deepens. Here’s a breakdown of diagnostics and treatment: Your veterinarian will usually do several quick, non-invasive tests: Eye exam with ophthalmoscope/slit lamp: The vet can sometimes see an ulcer by just looking at the eye, but sometimes the ulcer is so small the vet can not see it. Some of the possible signs of a corneal ulcer include, but are not limited to: Cloudiness, discharge, blood vessels, or foreign material. The best eye test to check for a corneal ulcer: Fluorescein stain test Fluorescein stain test (gold standard): A green dye highlights any defect in the corneal surface. Simple scratches glow bright green under blue light. Schirmer tear test: Measures tear production to rule out dry eye (KCS) as a cause. Tonometry: Measures intraocular pressure to rule out glaucoma or uveitis. Culture/cytology (if ulcer is severe or not healing): Checks for bacteria or fungi complicating the ulcer. Treatment depends on ulcer severity: 1. Simple superficial ulcer (small, recent, not infected): Topical antibiotic drops/ointment (broad spectrum like tobramycin, ciprofloxacin, ofloxacin, or triple antibiotic) to prevent infection. Atropine drops for pain relief (relaxes painful eye spasms). Elizabethan collar (E-collar) to prevent rubbing. Oral NSAIDs or pain meds if needed. Heals in ~5–7 days with proper care. 2. Complicated or deep ulcer (infected, not healing, melting): Frequent antibiotic drops (sometimes fortified or multiple types). Serum drops (autologous) or EDTA to block corneal “melting” (enzymatic breakdown). Oral antibiotics in severe infections. Anti-collagenase therapy if the cornea is rapidly thinning. Surgical options if risk of rupture: Conjunctival grafts Corneal grafts Temporary tarsorrhaphy (partial eyelid sewing shut to protect cornea) 3. Indolent/Non-healing ulcers (common in older dogs): Don’t heal normally due to defective epithelial adhesion. Special procedures: Grid keratotomy or diamond burr debridement to encourage healing. Bandage contact lens. 🚨 When to treat urgently Severe squinting, pawing at eye Cloudy or bulging cornea Yellow/green discharge Rapid worsening within hours Corneal ulcers are always an ocular emergency — they can go from mild to vision-threatening in a short time.
