- Management and Treatment
The elementary types of eye allergy are seasonal or perennial allergic conjunctivitis, vernal keratoconjunctivitis, atopic keratoconjunctivitis, contact allergic conjunctivitis and giant papillary conjunctivitis .
Seasonal and perennial allergic conjunctivitis
Seasonal allergic conjunctivitis ( SAC ) is by far the most common character of eye allergy. Patients experience symptoms in spring, summer or fall, depending on the character of plant pollens in the air. typical symptoms include :
- Clear, watery discharge
People with SAC may have chronic dark circles ( known as allergic shiners ) under their eyes. The eyelids may be puffy, and bright lights may be bothersome. SAC symptoms often accompany the fluid nose, sneezing and nasal congestion associated with hay fever and other seasonal allergies. The rub may be then annoying that patients rub their eyes frequently, making symptoms worse and potentially causing infection. perennial allergic conjunctivitis ( PAC ), as its list implies, occurs year-round. Symptoms are the lapp as with SAC, but tend to be milder. They are caused by reactions to dust mites, mold, favored dander or early family allergens, quite than pollen.
Vernal keratoconjunctivitis is a more serious eye allergy than SAC or PAC. While it can occur year-round, symptoms may worsen seasonally. It chiefly occurs in boys and young men ; about 75 percentage of patients besides have eczema or asthma. Symptoms include :
- Significant tearing and production of thick mucus
- The feeling of having something in the eye (foreign body sensation)
- Aversion to light (photophobia)
If left untreated, vernal keratoconjunctivitis can impair imagination .
This type of allergy chiefly affects older patients – by and large men with a history of allergic dermatitis. Symptoms of atopic keratoconjunctivitis can occur year-round and are exchangeable to those of vernal keratoconjunctivitis :
- Severe itching
- Significant production of thick mucus that, after sleep, may cause the eyelids to stick together
If left untreated, atopic keratoconjunctivitis can result in scar of the cornea and its delicate membrane .
Contact allergic conjunctivitis
This can result from aggravation by contact lenses or by the proteins from tears that bind to the airfoil of the lens. Symptoms include :
- Mucous discharge
- Lens discomfort
Giant papillary conjunctivitis
Associated with wearing reach lenses, giant papillary conjunctivitis is a austere form of contact allergic conjunctivitis in which individual fluid sauk, or papules, shape in the upper liner of the inside eyelid. Symptoms include :

Management and Treatment
The first approach path in managing seasonal or perennial forms of center allergy should be to avoid the allergens that trigger your symptoms. outdoor exposure :
- Stay indoors as much as possible when pollen counts are at their peak, usually during the midmorning and early evening, and when wind is blowing pollens around.
- Avoid using window fans that can draw pollens and molds into the house.
- Wear glasses or sunglasses when outdoors to minimize the amount of pollen getting into your eyes.
- Try not to rub your eyes, which will irritate them and could make your condition worse.
indoor photograph :
- Keep windows closed, and use air conditioning in your car and home. Air conditioning units should be kept clean.
- Reduce exposure to dust mites, especially in the bedroom. Use “mite-proof” covers for pillows, comforters and duvets, and mattresses and box springs. Wash your bedding frequently, using hot water (at least 130 degrees Fahrenheit).
- To limit exposure to mold, keep the humidity in your home low (between 30 and 50 percent) and clean your bathrooms, kitchen and basement regularly. Use a dehumidifier, especially in the basement and in other damp, humid places, and empty and clean it often. If mold is visible, clean it with detergent and a 5 percent bleach solution.
- Clean floors with a damp rag or mop, rather than dry-dusting or sweeping.
exposure to pets :
- Wash your hands immediately after petting any animals. Wash your clothes after visiting friends with pets.
- If you are allergic to a household pet, keep it out of your home as much as possible. If the pet must be inside, keep it out of the bedroom so you are not exposed to animal allergens while you sleep.
- Close the air ducts to your bedroom if you have forced-air or central heating or cooling. Replace carpeting with hardwood, tile or linoleum, all of which are easier to keep dander-free.
many allergens that gun trigger eye allergies are airborne, so you can ’ thyroxine always avoid them. Discuss your symptoms with your allergist to determine which discussion options are right for you .
OTC eyedrops and medications
nonprescription ( over-the-counter, or OTC ) eyedrops and oral medications are normally used for short-run relief of some symptoms. They may not relieve all symptoms, and prolonged manipulation of some OTC eyedrops may actually cause your stipulate to worsen.
- Tear substitutes: Artificial tears can temporarily wash allergens from the eye and also moisten the eyes, which often become dry when red and irritated. These drops, which can be refrigerated to provide additional soothing and comfort, are safe and can be used as often as needed.
- Decongestants: OTC decongestant eyedrops reduce the redness associated with eye allergies by narrowing the blood vessels in the eye. (Note: These should not be used by anyone with glaucoma.) They are available with a decongestant only or with a decongestant and an OTC antihistamine, which provides additional relief from itching. Because the drops are weak, they must be used frequently (four to six times a day). Do not use these OTC decongestant eyedrops for more than two to three days. Prolonged use can create a “ rally effect ” – increased swelling and inflammation that may last tied after discontinuing the drops. You may be companion with this if you have used decongestant nasal consonant sprays for more than three days and your nose has become even more clog than it was ahead .
- Oral antihistamines: While oral antihistamines can be mildly effective in relieving the itching associated with eye allergies, they may cause dry eyes and potentially worsen eye allergy symptoms. Also, some OTC versions of these medications can cause side effects such as sedation, excitability, dizziness or disturbed coordination.
Prescription eyedrops and medications
prescription eyedrops and oral medications besides are used to treat eye allergies. The prescription drops provide both short- and long-run target easing of eye allergy symptoms. See an allergist for technical care and stand-in .
- Antihistamine eyedrops: These can reduce the itching, redness and swelling associated with eye allergies. Although these drops provide quick relief, the effect may last only a few hours, and some must be used four times a day.
- Mast cell stabilizer eyedrops: These prevent the release of histamine and other substances that cause allergy symptoms. To prevent itching, the drops must be used before you’re exposed to an allergen.
- Antihistamine and mast cell stabilizer eyedrops: Some of the newest eyedrops have both an antihistamine and a mast cell stabilizer to treat and prevent eye allergies. They are used twice a day and provide quick, long-lasting relief of itching, redness, tearing and burning.
- NSAID eyedrops: Nonsteroidal anti-inflammatory drugs (NSAIDs) are available in eyedrops to relieve itching. These drops may cause stinging or burning when applied and may need to be used four times a day.
- Corticosteroid eyedrops: These can help treat chronic, severe eye allergy symptoms such as itching, redness and swelling. Long-term treatment with steroids (more than two weeks) should be done only under the supervision of an ophthalmologist; side effects of continued use include a risk of infection, glaucoma and cataracts.
- Nonsedating oral antihistamines: Prescription antihistamines can be mildly effective in relieving the itching associated with eye allergies. While they do not have the same sedating side effects as OTC antihistamines, these medications can cause dry eyes and worsen symptoms.
- Allergy shots (immunotherapy): Allergy shots work by improving an individual’s tolerance to the substance that causes an allergic reaction. Tiny amounts of the allergen are injected with gradually increasing doses over time. The treatment takes several months to achieve maximum results, and you may still be required to use medications to alleviate symptoms.
Children with eye allergies
