An eye allergy or allergic conjunctivitis is a condition that strikes when certain substances irritate the eyes, which can cause a reaction. This reaction has varied symptoms starting from inflammation to watering and even redness and an itching sensation. So how can you tell if you have an eye allergy? this article will tell you all you need to know!

Causes: to begin with, this is an immune response that happens when the eye comes in contact with substances like dirt, grime, pollutants, pollen, nettle, pet hair, smoke, mold and more, which may cause irritation. These are typically known as allergens. The immune system takes these allergens to be invaders and begins attacking the same by releasing chemicals that cause these allergic reactions. Also, an eye allergy may be a symptom or outcome of other conditions like asthma, hay fever, or even eczema.

Symptoms: the eye usually bears a pink or red appearance when the patient is suffering from an eye allergy. Also, watery eyes are a common sight during this condition while scaling around the eyes may also take place. Further, itching and burning sensation may be felt by the patient and swelling or puffiness can be seen. The symptoms may afflict one or both eyes. The patient may also have a runny nose or stuffy nose as well as nasal congestion.

Difference between eye allergy and pink eye: conjunctivitis or pink eye is usually caused due to bacteria or a virus that spreads infection in the eye. But eye allergy is caused due to a response of the immune system that leads to an allergic reaction. While the pink eye may be a contagious condition, an eye allergy is not.

Diagnosis: the diagnosis of an eye allergy will be done with the help of various tests conducted by an ophthalmologist. The skin prick test will help in introducing allergens to find out if the spot gets raised or suffers from inflammation. Also, the doctor will check for other ailments like asthma and eczema.

Treatment: there are varied methods of treating this condition. To begin with, the doctor may prescribe medication like decongestants and antihistamines as well as steroids for more severe and persistent cases. Also, injections may be prescribed in order to do away with the allergic reaction and eye drops containing olopatadine hydrochloride may also be used.

Home remedies: staying away from allergens and using a warm and clean washcloth over the eyes, for a few minutes every day, may help in relieving the painful symptoms of the condition.

Do not forget to consult your doctor before you try any natural or home based remedies.

Eye Allergies - What To Do & What Not To Do?

If you have got diabetes, then it is quite natural that you will soon face acute eye troubles. This is the reason diabetic patients are always suggested to keep their blood sugar levels controlled so that eye troubles can be easily avoided. Thorough medical check-up is required in order to detect conditions of the eyes. Some of the commonest eye troubles occurring due to diabetes are cataract, glaucoma, blurry vision, diabetic retinopathy and others. 

List of eye diseases caused by diabetes

1. Diabetic retinopathy: when the retina's smallest blood vessels get severely damaged due to increased blood sugar, then this kind of eye condition occurs. Early detection of this eye condition can save your eyes, but if it is too late, then nothing can be done, and it might even lead to blindness.

2. Cataract: fogging or clouding condition can bring this kind of condition and this can only be corrected by wearing proper corrective lenses. However, if you fail to control diabetes, then in spite of wearing glasses, your eye condition might get deteriorated day-by-day. Glared or blurred vision is the most common symptom in this regard. 

3. Glaucoma: when the eye fluid is not drained properly, then this kind of eye trouble occurs. In fact, eye pressure increases to a great extent as a result of which delicate eye nerves can get severely damaged. The blood vessels of the eyes can get clogged causing greater interruption in vision. Medicines can make aqueous humor to get drained in a proper manner, and thus you should go for a proper eye check-up so that you can acquire the requisite medicines. Some popular symptoms of glaucoma are headaches, eye aches, blurred vision, watery eyes, vision loss and others. 

4. Diabetic macular edema: this eye disease mainly occurs in the advanced stage of diabetic retinopathy. Macula is nothing, but the most delicate part of retina and when it gets swollen, then you might face this eye trouble. Only medications can help you to get rid of the same and thus immediate medical help is needed. 

5. Blurry vision: though this is quite a small and temporary eye issue for diabetic patients, but this condition might turn into a serious one if you neglect to correct the same in the very beginning. You might even face blindness due to negligence of this trouble. Also, fluctuating sugar-levels should be stabilized so that this kind of trouble can be easily tackled.

Eye Problems Caused by Diabetes

There are many common measures people take to improve their eyesight or to improve their vision, including wearing glasses, lenses, and many more. Here are some effective exercises, which can prove to be highly beneficial to improve your eye health:

1. Stretching
This is the most common and also one of the easiest to do. It requires you to just look up, hold for two seconds, look down, hold for two seconds and then repeat this procedure for each corner of your eye, which means top-left, top-right, bottom-left and bottom-right corners.

2. Flexing
This is simply rotating your eyes in circles. Roll your eyes in the clockwise direction for one minute and then roll your eyes in the anticlockwise direction for one minute.

3. Focus switching
This particular eye exercise is probably the most useful one to improve eye health. In this eye exercise, you have to hold something at a reading distance and cover the other eye. You then have to find something that is at least twenty feet away and trace its shape with one eye closed. With one eye closed, trace more shapes, which are twenty feet away.

4. Palming
This exercise is also very simple to perform. All you have to do is cover your eyes with your palms. Once you have done this, just wait and see that there are no bright flashes of light. If you see that there is a bright flash of light, just wait till they go. This is used primarily to distress the eyes.

5. Deep blinking
This is also an incredibly useful exercise for distance vision. What you have to do is to place some large letters are at a fair distance and then sit on a chair. You have to then close your eyes and tighten all your muscles for 5 seconds. After 5 seconds are over, you have to open your eyes and then you have to see the letters for a second or two. The more number of times you do this, the more clearly you will be able to see the letters after reopening your eyes.

However, these eye exercises are not universally accepted by all doctors.

Exercises to Improve Eye Health

In order to see clearly, the eyes need to be constantly lubricated. This function is performed by small glands located in the eyelids known as meibomian glands. These glands secrete oil onto the surface of the cornea through tiny openings on them. Malfunctioning of this gland can create an excessive amount of oil.

When oil accumulates on the eyelids, it encourages the bacteria present in the eye and the skin around it to multiply leading to inflammation. This condition is known as meibomianitis. Adults are at a higher risk of suffering from this condition as compared to children.

Some of the factors that could trigger meibomianitis are:

Allergic reactions
Fluctuation of hormones associated with puberty and adolescence
Acne and other skin conditions
Lice or mites on the eyelashes
Unsanitary contact lens solution
Contaminated eye makeup
Certain medications such as isotretinoin for acne that increases bacteria on the eyelids
However, in some cases, a clear trigger factor may not be identifiable.
Some of the characteristic symptoms of this disease are:

Dry eyes
Constant watering from the eyes
Inflammation and reddening of the eyelids
Burning sensation in the eyes
Itchiness
Flaking of skin around the infected eye
Heightened sensitivity to light
Excessive blinking
Crusting of eyelashes
Blurred vision
Frequent formation of sties
Loss of eyelashes or abnormal growth of eyelashes
Regular cleaning of the eyes with warm water and abstaining from the use of contact lenses and eye makeup can help reduce irritation and manage the inflammation. Additionally, the doctor may also prescribe antibiotics or steroids in the form of pills, eye creams or drops. Artificial tears may also be recommended to patients exhibiting dry eye symptoms.

Meibomianitis - 8 Things That Can Trigger It!

Hypertension is a killer disease whose symptoms develop late when the damage is in advanced stages. Hypertensive Retinopathy is one such disease.

It damages the retina of eyes. Since retina is responsible for vision formation, Hypertensive Retinopathy can result in loss of vision. It is of grave concern that in most cases, Hypertensive Retinopathy is diagnosed later.

This is due to the fact that there are often no symptoms in the early stages of the disease. In some cases, where symptoms do manifest, patients may experience pain in the eyes, reduced vision, or headache.

What Happens in Hypertensive Retinopathy

People suffering from long term hypertension are susceptible to Hypertensive Retinopathy. Long-term hypertension affects the small and narrow blood vessels that join arteries to capillary blood vessels taking blood to different parts of the eye. These blood vessels become narrow with time if hypertension in the eyes continues unabated. This narrowing is more common in young adults compared to older people. Such unabated systemic hypertension also leads to leakage of fluid. This is why in some cases of Hypertensive Retinopathy, patients may experience exudation. Ultimately, Hypertensive Retinopathy may lead to damage to retinal blood vessels.

Risk Factors

Long standing hypertension is the number one risk factor for Hypertensive Retinopathy. People who are suffering from longer hypertension become most susceptible for this ailment.

However, studies have shown that hypertension for more than 5 years can even make people susceptible to this ailment.

Diagnosis

Diagnosis is done by Funduscopic Examination. The doctor would look at the eyes of the patient through an Ophthalmoscope which has different lenses. The Ophthalmoscope illuminates the retina and the doctor looks at the retina with different lenses. He can get a view of the retina, including blood vessels and optic nerve disks.

Findings of Diagnosis

For a person suffering from Hypertensive Retinopathy, this examination is likely to show:

Constriction of the arterioles.

Changes in the walls of retinal blood vessels.

Flame-shaped hemorrhages in the retina.

Yellow and hard exudates.

Spots in the shape of cotton wool.

Swelling of the optic disc.

Treatment

The primary treatment for Hypertensive Retinopathy is controlling blood pressure of the eyes. Some lifestyle changes like reducing the intake of salt, avoiding tobacco, etc., may bring down or control systemic hypertension in the eyes. In many cases, doctors may just recommend lifestyle modifications. Nevertheless, it completely depends on the extent of the damage and whether or not there is any fluid accumulation.

If the doctor feels that lifestyle modification is not enough, he may go for medicines that help the patients to control blood pressure effectively.

If the problem is in advanced stages and there is fluid accumulation behind the retina, the doctor may go for Intravitreal injection or Laser Therapy to control the edema.

Conclusion

Eyes are one of the most significant part of the body, this is why it is important for people to take care of it. In case of disease like Hypertensive Retinopathy, one must consult a doctor before opting any treatment or medicines.
