Amblyopia is commonly known as'lazy eye. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to'see' and develop binocularity, that is the ability to perceive depth (stereoacuity). This occurs in the first 8 to 10 years of life. 

Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions (adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to'see' and becomes'lazy. This condition is seen in 1-4% of population.

The common causes for dissimilar images or amblyopia are:
1. Misalignment of the eyes or squint: it is the primary reason for amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different, resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.

2. Refractive amblyopia:
A. Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5d of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
B. High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.

3. Cloudiness in visual system or visual deprivation amblyopia: any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood (drooping of one eyelid, eyelid swelling, patching of one eye).

Treatment for amblyopia
For treatment of amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.

Patching or occlusion of the good eye
This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye'learns to see. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.

To be effective, treatment should be implement as early as possible, within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.

Conjunctivitis - How Can Ayurveda Help?

Bloodshot eyes aren't exactly the best feature of a person! When a person's eyes are bloodshot, it is quite easy to 'see' that something is wrong! Eyes are possibly the most delicate organs of the body, and are all the more vulnerable to infections such as 'subconjunctival haemorrhage'. However, as dour as such terms may sound, there is a lot which really should be known about them!

The eye has a thin layer which goes by the name of the conjunctiva, which covers a part called the sclera. Many a times, especially in the case of children, if an injury unfortunately occurs in the eye, there are chances that it may form subconjunctival haemorrhage.

The reason why this occurs is that there are some of the very small blood vessels in a person's eye break. The reason for this, apart from an injury could also be on account of a sudden increase in the blood pressure of the person. This usually takes place due to some very strenuous lifting exercise but also can occur due to laughing or sneezing!

The occurrence of a subconjunctival haemorrhage can also be closely linked to the consumption of pills which thin the blood such as aspirin.

Treating Subconjunctival Haemorrhage

Now, considering the fact that such a haemorrhage has the potential to look quite scary, it may be natural for a person to react proactively. However, in many cases this is not required at all. As a matter of fact, the issue clears up within a couple of weeks at the maximum and a week and a half, on average. If this does not happen to be the case, it is a signal that a medical professional should take a look at the patient's eye.

In many instances, a person may not even get to know that he or she is suffering from a subconjunctival haemorrhage as there is no effect on the vision of the person and he or she would probably get to know that this is the case by taking a look in the mirror or being informed of his or her eye looking red.

In order to treat a subconjunctival haemorrhage in an effective manner, the first thing to be done by a person is to avoid any medication which could be causing it. Also, it is quite important not to rub one's eye as this really does slow down the healing process.

Artificial tears help soothe the eye but they do not hasten the rate of repair. A subconjunctival haemorrhage may occur, but if a person follows the right steps, his or her vision can consistently remain 20/20!

All About Subconjunctival Haemorrhage

While it's assumed that numerous eye injuries are inflicted at work, just about the same number of them may happen while at home. Luckily, most eye wounds are preventable. Find ways to prevent eye injuries, as the eyes are very sensitive and delicate.
Here is a list of some of the most common eye injuries and tips on how to prevent them:

1. A lot of eye injuries happen from dust particles entering the eyes, causing itching and burning sensation. Protective glasses should be worn when doing any kind of activity in a dusty area with flying particles.

2. Pencils, scissors, forks, knives and all similar sharp objects can cause a serious eye injury. Day to day household items like bungee cords, wire coat hangers, rubber bands and fishhooks are capable of causing eye injuries. You must always remain aware and super conscious while using such objects.

3. While performing activities such as dusting, sweeping or lawn mowing, make sure to protect your 
eyes well as dust is involved.

4. Children are very curious by nature. Thus, all hazardous stuff like fertilizers, acids should be kept away from their reach. These contain harmful chemicals, which may inflict fatal damage to the eyes.

5. Cooking powder and spices like chili powder can cause injury to the eye. Always wash your hands 
after using these items, so that you don't harm the eyes if you by chance rub them with your hands.

6. Precautions should be taken while dealing with heat or boiling water or oil. They may spill and cause damage to the eyes.

7. Secure floor coverings and railings. On the off chance that a kid or elderly man lives in your home, use a safety gate at the top and base of stairs, and consider covering sharp furniture edges and corners with a padding material.

8. While travelling in a car, abrupt jerking or breaks may cause the head to bump and cause injury to the eye. Always put on your seat belt and do not allow children to sit in the front of a car.

9. Many modern toys, which are very attractive have got sharp edges because of their fancy design. Abstain children from playing with these kinds of toys.

10.  Laser pointers, a common fun gadget for children is very harmful and causes permanent damage to the retina. Stay away from laser pointers.

11. Wear eye gear to protect your eyes during sports activities. Also wear goggles during swimming as chlorine in swimming pool water damages the eyes.

Eye injuries may happen out of nowhere. You must always remain alert to avoid eye injuries.

Most Common Eye Injuries That Happen and Prevention Tips

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.
