You will find that one of the things your veterinarian looks at during your puppy's annual exam is his eyes. Sometimes things are not seen by owners in the early stages, but there are other things that are immediately visible. Although some are more serious than others, it is important to understand the most common eye diseases that affect our dogs. This is not a complete list of disorders, but one of the most common.
# 1 – Corneal ulcers
Corneal ulcers are basically scratches or erosions on the cornea that typically occur due to injury, but can be caused by other diseases. Although they're usually not as bad as they sound, corneal ulcers should be treated as soon as you notice symptoms. Partial closure of the eye, rubbing of the face and excessive tear production are signs that something is wrong with your dog's eye and an ulcer may be the cause. Cat scratches, playing with other dogs, thorns, and even tall grass can damage your dog's eye.

# 2 – Waterfalls
Waterfalls affect the lens of the dog's eye, causing deterioration of vision and eventually complete blindness. Many owners mistake nuclear sclerosis, a common and similar condition that occurs as dogs age, for falls. But the two are very different. With the normal aging process of nuclear sclerosis, vision may be affected, but not to the extent of a waterfall. Falls are usually genetic in dogs, but some conditions like diabetes can contribute to the disorder. Falls can be repaired surgically, although this is an expensive procedure and not usually recommended by veterinarians unless vision is repaired with certainty.
# 3 – Dry eye
Dry eye, also called keratoconjunctivitis sicca (KCS), is a condition in which the tear glands in dogs produce fewer tears than normal. In some cases, tear production is completely absent. Dogs with KCS usually have a thick, yellow discharge from their eyes. Their eyes turn red. The cornea eventually browns. If KCS is left untreated, it will eventually lead to blindness. Medications are often used to treat the symptoms of KCS. In severe cases, surgery to reroute a salivary duct to the eye is an option.
#4 – Glaucoma
Eyes have a system of fluid and drainage that helps them maintain proper prere inside the skull. When this is interrupted, the prere in the eye increases. Glaucoma is painful and symptoms include redness, enlarged eye, dilated pupils, visible third eyelid, increased tear production and corneal opacity. Glaucoma leads to blindness, so early treatment is the best choice. There are two types of glaucoma – primary and secondary. Primary is a problem with the eye drainage itself, while secondary is a problem with the drainage due to another infection. About 40% of dogs with glaucoma lose vision in the affected eye, so treatment is essential.

# 5 – Progressive retinal atrophy
Progressive retinal atrophy or PRA is a degeneration of the retinal tie in the eye that leads to blindness. PRA is a genetically inherited disorder, therefore breeds susceptible to this disease must be tested before breeding. According to Animal Eye Care, "The slow loss of vision is like a dimmer switch to reduce the brightness of the light in a room. When light is slowly reduced for a long time, our eyes adapt and the change is not noticed until darkness occurs Situation occurs with progressive retinal atrophy in animals, often the condition is not noticed until the condition progresses significantly. "Unfortunately, there is no cure. Treatment for PRA. Fortunately, the condition is painless and dogs usually adjust quite well to life with minimal to no vision. Dogs have a third eyelid. A prolapse of this eyelid is called cherry eye. The third eyelid is normally hidden from humans. Is held by special bands. When these ligaments fail for any reason, the third eyelid appears and pink / red fleshy tie is visible, giving the condition its name. Cherry eye is most commonly repaired by surgery and is a genetic condition that usually affects both eyes over time (if the dog is affected). Veterinary treatment should be sought, as cherry eye causes dry eye in your dog, leading to blindness over time.
#7 – Entropion / Ectropion
Entropion is a condition where the eyelid grows inward toward the eyeball and the eyelashes or sometimes the lid itself rubs against the eyeball. This leads to corneal ulcers, which in turn lead to other diseases, including blindness, if left untreated. It is most often a genetic condition, but can also be caused by chronic strabismus due to other eye conditions. Conversely, ectropion is a condition in which the eyelid falls and rolls out of the eye. This causes red, watery and irritated eyes and can be uncomfortable for dogs. Entropion can be repaired with surgery, while ectropion is usually left alone, depending on severity.

# 8 – Conjunctivitis
Conjunctivitis or pink eye can also occur in our dogs. This condition is basically the inflammation of the conjunctiva. Generally thinks of it as a symptom rather than a disorder per se. Physical irritation as well as scratching, dust or entropion and allergies are common causes of conjunctivitis in dogs. However, bacterial and viral infections occur in the eye, and the disease can occur on its own without a main cause. Treatment is generally simple and a veterinarian should be consulted if you notice symptoms such as redness, drainage and discomfort.
