Corneal Injuries

Corneal injuries in horses are caused by trauma and can vary widely in severity. They represent a potentially serious threat to vision and, in severe cases, to the integrity of the eye itself. Deep corneal injuries are absolute emergencies and require immediate veterinary care.

Causes

Corneal injuries in horses can result from a variety of causes. The most common include:

  • Foreign body trauma
    Horses are frequently exposed to dust, sand, grass or small particles that can irritate or damage the corneal surface.
  • Infectious complications
    Bacteria, viruses or fungi may invade damaged corneal tissue and cause inflammation. Bacterial infections are particularly dangerous, as they can rapidly lead to corneal ulcers.

Symptoms

Corneal defects may present with a range of clinical signs, including:

  • Increased blinking or keeping the eye closed, often due to light sensitivity
  • Excessive tearing or purulent discharge, indicating irritation or infection
  • Redness of the eye, especially the conjunctiva
  • Clouding or a milky appearance of the cornea
  • Swelling of the eyelids or surrounding tissues
  • Signs of pain or restlessness, such as head rubbing or pronounced photophobia

Course of Disease

Diagnosis

A complete ophthalmic examination is performed to assess all affected structures and determine the appropriate treatment plan. Corneal injuries are visualized using fluorescein staining, a green dye that highlights defects and ulcers of the cornea.

Treatment

Superficial corneal injuries can often be treated successfully with removal of damaged corneal tissue through keratectomy combined with local medical therapy. These cases usually show good healing potential.

Deep corneal injuries may require surgical intervention, including corneal suturing with or without conjunctival grafting. Additional procedures involving internal ocular structures may be necessary depending on the extent of damage, such as intraocular hemorrhage. In cases of trauma associated with irreversible blindness, removal of the eye may be indicated.

When surgery is required, the eye is thoroughly flushed with antiseptic solutions and the periocular area is carefully prepared immediately before the procedure. Postoperatively, horses receive intensive local treatment to promote uncomplicated healing. Many patients are fitted with a subpalpebral lavage catheter, allowing frequent and gentle administration of ophthalmic medications.

Systemic pain management and additional medications are provided as needed based on clinical findings and progression.

Prognosis

Prognosis depends on the severity of the injury and the individual course of healing and is often considered guarded. Blunt trauma in particular can cause pressure and traction forces within the eye, leading to secondary damage. Infection and impaired wound healing represent additional potential complications.

Early diagnosis and prompt, appropriate treatment are critical factors in preserving vision and ocular comfort.

Frequently Asked Questions (FAQ)

When is a corneal injury an emergency?

Any corneal injury should be taken seriously. Deep lesions, severe pain, marked cloudiness or sudden vision loss are ophthalmic emergencies and require immediate treatment to prevent permanent damage.

How are corneal injuries in horses diagnosed?

Diagnosis is based on a complete ophthalmic examination. Fluorescein dye is used to clearly visualise corneal defects and assess their extent and depth.

Can a horse fully recover vision after a corneal injury?

Prognosis depends on the severity and course of the injury. Superficial lesions often heal well, while deep trauma or complications such as infection may result in lasting visual impairment.
