Sometimes you might notice your pet getting restless with a swollen or a red eye. He might occasionally rub his paws against his eyes in an effort to ease the discomfort. Never ignore such a condition in your pet. You never know if it is a kind of interim allergic reaction or the first signs of a terminal eye disease. Various infectious ocular eye problems start with red and sensitive eyes. Usually a few drops of eye medicine might help in treating the problem. Otherwise, major eye surgeries need to be performed if the infection is severe. Below, we have listed the various eye diseases that generally occur in dogs.
This disease is characterized by itching, due to swollen mucous
membranes of the eyes. Increased blood flow makes the eyes appear red
and swollen. Different viruses and bacteria transmit this disease. Ticks
may also carry certain parasites that give birth to conjunctivitis. Eye
discharge is generally clear or mucus-ridden, depending on the severity
of the condition.
Chronic Superficial 'Keratitis' or 'Degenerative Pannus' is an
ophthalmic disorder that causes pigmentation and formation of
superficial blood vessels on the eyes. If left untreated for a long
time, it might lead to decrease in the visionary level of the animal.
Though not painful, a thick ropy discharge is seen in severe cases.
Sometimes, Keratoconjunctivitis Sicca also gives birth to this disease.
This disease is mostly seen in young dogs and is characterized by a
prolapse of the gland of the third eyelid. Here, the gland protrudes and
gets inflamed. Generally, if one eye catches the disease, the other eye
gets easily vulnerable to the problem. In such cases, surgical
replacement of the gland becomes a necessity to get rid of the disease.
Here, the outer cover of the eyeball (sclera) gets inflamed. It
generally involves only one eye. A red, swollen and hard cyst-like
structure can be seen on the infected eye. Various parasitic diseases
like 'Toxoplasmosis' or 'Lyme Disease' lead to Scleritis. It can be
cured with the help of steroids. But, in severe cases, the disease might
also lead to permanent loss of eyesight.
This disease can be very painful, and might be the result of harmful
parasitic disease like 'Toxoplasmosis'. Here, the entire uveal tract, or
a part of it, gets infected and inflamed. Signs of the disease include
moist and sensitive eyes, eyelid spasms and small pupils. This ocular
disease is also common in humans and might lead to damaged vision, if
left untreated for a long time.
This is a serious eye disorder that requires immediate medical
supervision. It occurs when the free flow of eye fluids is obstructed.
Thus, a huge amount of pressure builds up in the eyeball and gives rise
to cloudy pupils and swollen red eyes. The situation, if not controlled
immediately, leads to damaged retina and optic nerve and might even
result in the removal of the infected eye.
Cataract is caused due to the presence of white opacities in the lens
of the eye. The disease can either be congenital or acquired after
birth. Sometimes, conditions like 'Diabetes Mellitus' also leads to
cataract. The disease might also be acquired due to various infections,
injuries or radiation therapies. Acute cases of cataract might impair
vision. Surgery is unavoidable in most cases.
Blepharitis is a serious condition, characterized by infected, red and
swollen eyelids. Various signs include puffy eyelids, sensitive eyes,
spasm of eyelid, abscesses, scales and a thick discharge from the eyes.
Hormonal disorders, nutritional imbalance, chemical reactions, parasitic
infections and even insect bites may lead to the problem.
A dog might also suffer from various eye infections due to certain
abnormalities in the growth of the eyelashes. Sometimes, the eyelashes
turn inward and constantly rub on the surface of the eye. This condition
is known as 'Entropion'. Sometimes, two lashes may grow from a single
hair follicle (Districhiasis) and the extra lash may be a cause of
severe eye irritation. All this leads to watery eyes.
If you notice any of these eye problems in your dog, immediately
consult your veterinarian. Prolonging diagnosis and surgery result in
irreversible ocular damages in most of these cases.
