Understanding the Cornea
The cornea is a vital component of the eye that plays a crucial role in vision. It is the clear, front part of the eyeball that allows light to enter and refracts it onto the retina, where the visual processing takes place.
The cornea consists of three distinct layers, each serving a specific function: the epithelium, the stroma, and Descemet’s membrane.
The epithelium is the outermost layer of the cornea, acting as a protective barrier against foreign particles and pathogens. It also provides a smooth surface for the tear film to spread evenly, ensuring clear vision.
Beneath the epithelium lies the stroma, which constitutes the majority of the cornea’s thickness. Composed of collagen fibers arranged in an intricate pattern, the stroma provides structural support and contributes to the cornea’s transparency.
The deepest layer of the cornea is called Descemet’s membrane. It serves as a barrier and helps maintain the shape and integrity of the cornea.
An erosion or ulceration through these layers can result in a corneal ulcer, a potentially serious condition that requires prompt medical attention.
Special stains and microscopic examination are necessary to visualize and assess the condition of the cornea’s layers, allowing veterinarians to determine the extent of the damage and establish an appropriate treatment plan.
Understanding the structure and function of the cornea is vital in comprehending the causes, symptoms, and treatment options for corneal ulcers in dogs. By gaining insight into these details, pet owners can better grasp the importance of seeking veterinary care to ensure the well-being and vision of their beloved companions.
Causes of Corneal Ulcers in Dogs
Corneal ulcers in dogs can be caused by various factors, including trauma, chemical burns, bacterial infections, viral infections, and underlying diseases. These factors can lead to the development of ulcers on the cornea, the transparent, shiny membrane at the front of the eyeball.
Trauma: Dogs may develop corneal ulcers from trauma, such as rubbing their eyes on rough surfaces or being scratched by another animal.
Chemical burns: Exposure to certain chemicals or irritants can cause burns on the cornea, leading to ulcers.
Bacterial infections: Bacteria can infect the cornea, either directly or as a secondary complication from infections elsewhere in the body, resulting in ulcers.
Viral infections: Viruses can also cause corneal ulcers, either directly in the eye or due to systemic viral infections.
Underlying diseases: Certain underlying diseases like epithelial dystrophy, keratoconjunctivitis sicca (dry eye), and endocrine diseases can make dogs more susceptible to corneal ulcers.
It is important for pet owners to be aware of these potential causes and take necessary precautions to protect their dogs’ eyes. Prompt identification of any trauma or signs of infection should be followed by immediate veterinary care to prevent the development of corneal ulcers.

Symptoms and Diagnosis of Corneal Ulcers
Corneal ulcers in dogs can cause a range of symptoms, often indicating the discomfort and pain experienced by the affected animal. One common symptom is pain, which leads dogs to rub their eyes in an attempt to alleviate the discomfort. Consequently, dogs may keep their eyes tightly closed to minimize irritation. Another notable symptom is the presence of discharge, which can appear as watery or pus-like fluid.
Diagnosing corneal ulcers can be challenging because superficial ulcers may not be visible without specific tests and equipment. To identify and assess ulcers, veterinarians commonly rely on a fluorescein stain test, a non-invasive diagnostic tool often used in ophthalmology. This test involves applying a special fluorescent dye (fluorescein) to the eye’s surface. The dye adheres to areas of ulceration, making them visible under special ophthalmic lights and filters.
A fluorescein stain test is a valuable diagnostic method that enables veterinarians to detect and evaluate corneal ulcers effectively.
Fluorescein Stain Test Procedure:
- Clean the eye with a sterile saline solution.
- Apply the fluorescein dye to the cornea using a sterile strip or dropper.
- Allow the dye to distribute evenly over the cornea.
- Use an ophthalmic light source with filters to visualize the stained areas.
- Examine the cornea under different lighting conditions to assess the extent and depth of the ulcer.
The fluorescein stain test is not only beneficial for detecting ulcers but also for monitoring the healing process of existing ones. It allows veterinary professionals to assess the progress of treatment and make informed decisions about the appropriate course of action. By using this diagnostic method, veterinarians can provide timely and effective care for dogs with corneal ulcers.
Furthermore, it is essential to note that accurate diagnosis and prompt treatment are crucial to prevent complications associated with corneal ulcers and maintain the overall ocular health of dogs.
