Ophthalmic Emergencies in the Field.

The research article details the prevalence and management of ophthalmic emergencies in horses, explaining diagnostic tools and surgical procedures for various eye conditions.

Overview of Ophthalmic Emergencies

• Ophthalmic emergencies, or eye emergencies, are a significant issue in equine practice, accounting for up to 20% of all emergencies. These emergencies can involve the periocular region (the area surrounding the eye), the adnexa (appendages of the eye like eyelids and tear glands) or the globe (the eyeball itself).

Eye Examination and Restraint

• Dealing with eye conditions in horses requires exceptional care because it often involves restraining horses that are in pain. This calls for not only physical ability but also substantial experience.
• Practitioners also need to understand how to perform a thorough eye examination. This step is crucial to correctly diagnose the issue and determine the most appropriate treatment.

Diagnostic Tests

• Several diagnostic tests are required in the assessment of ophthalmic emergencies, including corneal cytology, ultrasound, and tonometry.
• Corneal cytology involves the microscopic examination of cells obtained from the cornea.
• Ultrasound uses sound waves to create a picture of the eye’s interior structure, providing valuable information about possible injuries or lesions.
• Tonometry measures the pressure within the eye, which is critical to diagnose conditions like glaucoma.

Surgical Procedures

• The study talks about common standing surgical procedures, including eyelid repair and subpalpebral lavage system installation.
• Eyelid repair is necessary when a horse’s eyelid is damaged or torn, a common occurrence in the field.
• The installation of a subpalpebral lavage system enables easier administration of medication to the eye over a longer period. This is particularly useful when the horse needs frequent doses of medication.

Treatment

• The treatment for ophthalmic emergencies frequently necessitates the repeated administration of various medicines, emphasizing the need for accurate diagnosis and specific treatment plans.
