[Common eye diseases]
Conjunctivitis is one of the most common eye diseases in dogs. Surface or substantial inflammatory invasion of the conjunctiva is referred to as conjunctivitis. It is usually a simple conjunctivitis, such as foreign body, nasolacrimal duct occlusion, drugs, and trauma. However, there are also secondary conditions of other diseases such as canine distemper, infectious hepatitis, leptospirosis, and other infectious diseases. Dogs often suffer from a number of internal diseases and parasitic diseases.
1. Dogs with keratitis will feel significant pain, so they will scratch and rub their eyes often.
2. Shyness, lacrimation, conjunctival congestion, and increased discharge, the nature of which varies with the condition.
3. Severe cases may be plasmacy, some mucous or mucopurulent, and some purulent. The upper and lower eyelids are often bonded with discharged purulent secretions.
4. If the development continues, the cornea can ulcerate or even tear.
1. Wash the affected eye with saline and 2 ~ 3% boric acid water or 1% alum solution.
2. Antibiotic eye drops ointment are dabbed or applied to the conjunctival surface 3-4 times a day.
3. If there is severe pain, use 1-2% bupivacaine hydrochloride to spot the eye.
4. Septic conjunctivitis can be used for 0.5% procaine hydrochloride solution 1 ml dissolved penicillin 50,000 international units, add hydrocortisone .5 ml 2.5 intraconjunctival injection 5 mg or fundus closure, good results.
Do not expose your dog’s eyes to bright light during the treatment of conjunctivitis. Handle and clean carefully when cleaning. Keep the environment dry and hygienic, and do not touch outside until the dog recovers
Keratoconus is an eye disease in which the corneal tissue of the dog is damaged or infected. Corneal ulcers form opaque gray scars called corneal shadows that are caused primarily by corneal trauma, foreign bodies, and chemical irritation. Adjacent tissue diseases conjunctivitis, anterior uveitis, etc. can precipitate the disease. Keratoconjunctivitis is usually classified as superficial, pigmented, deep, and ulcerated.
1. The common symptoms of keratitis are photophobia, tearing, pain, flushing of the conjunctiva, swelling, and closed or semi-closed eyelids.
2. Pericorneal vascular congestion, corneal cloudiness, defects, or ulcers.
3. Those that eat due to trauma have a rough and uneven corneal surface and a cloudy cornea, some are milder and just a thin translucent opacity. Some are thicker, with an opaque white film, and thus the dog can go blind.
4. Severe dogs can have corneal perforations.
1. To control or prevent corneal infection, after cleaning the dog’s diseased eye, apply a low concentration of antibiotic eye drops, such as 0.5-1 streptomycin, 0.25% chloramphenicol, 0.5% tetracycline, and 0.5-1% neomycin, and spot the eye 4-6 times a day with 1-2 drops each time.
2. Severely ill dogs can use highly concentrated eye drops such as 40,000 units/mL penicillin, 5% streptomycin, and 40,000 units/mL polymyxin, dabbed in the eye every half hour. Or apply antibiotic ointment.
3. To promote corneal absorption, use 1-2% Dionine or 1% white or yellow descending mercury eye ointment, or sprinkle with glycerol powder.
The principles of treating keratitis are to eliminate the cause, reduce inflammation and analgesia, promote absorption and tissue repair, and reduce scar formation. Avoid exposure to unhygienic environments.
A disease caused by high eye pressure in dogs with glaucoma pressure inside the eye in order to keep the eye in a ball shape. There are some breeds of dogs, such as Cocker Spaniels, Huskies, and Pine Barons, that are prone to primary causes. Secondary causes are mostly some ophthalmia, uveitis, lens detachment, hemorrhage, etc. If glaucoma is left untreated, it may lead to blindness and parents should pay special attention.
1. The dog’s eyes disappear or reflect light slowly, and the eyes cry out in pain.
2. When viewed from the side, the eyes bulge out, which is due to eye congestion caused by high eye pressure.
3. The color of the eye is green or red.
4. The surface of the eye is cloudy due to edema of the corneal layer.
5. Dilate the pupil.
1. IOP-lowering medications are effective at the disease site and poorly effective later. 1% cortisone ophthalmic, 2% trichothecene ophthalmic, 1 time/6 hours may be used.
II. II. Diclofenac changed to .2-4. 4 mg/kg body weight from 1 dose/8 hr to 1 dose/12 hr.
3. Give your dog a potassium supplement.
4. Primary glaucoma is mostly bilateral and can be treated with medication or surgery.
Glaucoma is common in polar animals such as huskies. The average onset of glaucoma in other animals such as bajid, pine, poodle, maltese, and shih tzu is 4-9 years of age. Secondary glaucoma is common in Boston, Barleytown, and West Highland White Terrier, with an average onset time of 2-6 years.
IV. Eyelid entropion
IV. Eyelid entropion
A dog with entropion is a disease in which the eyelid rim turns inward, causing the eyelashes and eyelid hairs to irritate the conjunctiva and cornea, causing an abnormal manifestation of inflammation of the latter. The disease is classified as congenital or spastic. However, almost all cases prove that the disease is hereditary, occurs in most dogs around 6 months after birth, and must be corrected surgically. Spastic acquired entropion of the eyelid is caused by spasm of the orbicularis oculi muscle and is mostly secondary to conjunctivitis and keratitis. In addition, scar contraction after eyelid conjunctival surgery can also lead to entropion.
1. The edge of the eyelid on one or both sides of the dog flips inward, causing some or all of the eyelashes to fall back toward the surface of the eye and irritate the eye.
2. After the onset of inflammation, dogs spend time in tears, pain, and shyness.
3. Dogs often rub their eyes with their front paws, twitch their eyelids, and have increased eye discharge.
4. If left unattended and untreated, corneal vascular hyperplasia, pigmentation, and corneal ulcers can lead to severe vision loss or even blindness.
1. Aggressively treat spastic entropion due to conjunctivitis and keratitis by giving analgesics and mustard injections of 5% of 0. procaine penicillin solution.
2. If medication is ineffective, surgical treatment is required to correct the problem.
3. Dogs with mild entropion can be treated with eyelash plucking, even if they have conjunctivitis and keratitis.
When a dog suffers from entropion of the eyelid, the eyelashes will constantly irritate the cornea and conjunctiva, plus the irritation of the dog constantly rubbing his eyes in discomfort, which can easily become chronic keratitis or conjunctivitis.
V. Cleaning methods
[Clean dog eyes]
V. Cleaning methods
1. You can wipe the eye dirt from around the dog’s eyes with a wet cotton ball, but do not use a dry cotton ball, as the lint will remain in the corner of the dog’s eyes.
2. A damp cloth or cotton ball can be moistened with 2% to 3% borax water for cleaning eye dirt from the dog’s eyes.
3. If your dog has a mild inflammation, you can choose chloramphenicol eye drops to reduce inflammation. These drops are mild and will not irritate the dog’s eyes.
4. When dropping eye drops, parents should bring the hand holding the drops closer from behind. If the dog sees the drops, he will try to resist and run away~
Clean your dog’s eyes once a day and remove any dirt from the eyes in a timely manner. When cleaning the eyes with drops, be careful to avoid leaving marks on the dog’s fur. Be as gentle as possible when giving eye drops, but move quickly and keep the tip of the bottle out of the dog’s eyes. At first not used to it, the dog will resist, if the resistance is very serious, stop first. The eyes are the windows to the soul, and a dog’s eyes have many special uses. Not only can they accurately measure the distance of objects in front of them, but dogs still have a strong ability to discern objects in low light. If your dog has big watery eyes, I am sure it will bring love to your relatives, friends and neighbors.
