Loss of Vision & Disability - How Can Psychological Rehabilitation Help?

Amblyopia or Lazy eye is the eye condition in which vision is reduced and cannot be corrected with glasses or contact lenses. All the images seen by the amblyopic eye are not fully acknowledged by the brain. It always affects only one eye, but may be accompanied with reduction of vision in both eyes. It can cause loss of vision, including loss of depth perception and two-eyed 3D vision. It's treatment can yield improvements at any age, but early detection can offer the best chances for a cure. Recent research has proven that lazy eye treatment can be successful in older children and adults. Comprehensive vision examinations are required for infants, toddlers, and pre-school children for the detection of lazy eye or amblyopia.

When the brain parts related with visual processing do not function properly, problems arise with such visual functions as the perception of movement, depth perception and fine detail (acuity, clear eyesight and sharp vision). Amblyopia is the most prevalent neurological defect of vision in children and adults resulting from developmental problems in the brain. Any interference with clear vision in either eye during the first six years or 'critical' period of visual and brain development can cause a lazy eye.

Constant strabismus or the constant turn of one eye in any direction, be it inward turn or crossed eye is one of common causes of amblyopia. The differences in vision or it's prescription between the two eyes leads to refractive amblyopia. Sometimes congenital disorders or a physical blockage of an eye due to trauma, drooping lids, cataract or a blocked tear duct can also lead to amblyopia. Many parents and children are not aware of any symptoms, as amblyopia usually occurs in one eye only and a lazy eye condition can exist without a noticeable eye turn. The visual acuity tests in addition to the 20/20 eye test charts and eye examination with cycloplegic drops by ophthalmologists are necessary to detect lazy eye.

Vision therapy for the eyes and brain is a highly effective non-surgical treatment for lazy eye. It is a progressive program of vision exercises customized to fit the visual needs of each patient. It is conducted at the clinic and occasionally supplemented with exercises to be done at home or workplace. It improve visual comfort, ease, and efficiency and change how a patient processes or interprets visual information. When considering treatment options, it is important to understand that lazy eye results from neurological deficit or problems in the brain and surgery for lazy eye is performed on the muscles on the outside of the eye. Most of the cases, lazy eye surgery provides cosmetic benefits and does not improve the patient's vision, hence options for vision improvement should be exhausted before eye muscle surgery is considered.

Lazy Eye or Amblyopia - Symptoms and Cure

Eye allergies are characterized by red and itchy eyes which may result from various allergens coming in contact with the eye. Eye allergies can cause swelling of the eyelids, redness in the eyes and may also lead to conjunctivitis. Conventional treatments prescribe eye drops containing chemicals that may aggravate the condition.

Homeopathy-the best natural treatment for eye allergies-

The allopathic system relies mainly on steroids and anti-allergic medicines for the treatment of allergic conjunctivitis. Even  then, it is unable to cure the allergy. It only ends up controlling it or keeping the symptoms under check. In homeopathy, the intention is to completely cure the allergy. Homeopathy recognises that the immune system of the body sometimes overreacts to some seemingly harmless things. This overreaction of the body is the root cause of problem. 

Therefore, it tries to correct the immune system. In this the medicines that are used by homeopathy are perfectly natural medicines. None of the medicines are chemical in nature. They are made from natural sources like plants or fruits or vegetables or minerals. The basic material is further diluted by a special mechanism which reduces the content of the original matter while increasing its latent healing powers. That is why these natural homeopathic medicines do not have any side effects.

The homeopathic remedies for eye allergies are:

1. Euphrasia

This remedy is used to treat allergies which cause watery discharge from the eyes and which tends to have burning sensation on the skin. The condition tends to aggravate during the evening and in closed spaces.

2. Argentum nitricum

Argentum nitricum is used to treat eye allergies which show symptoms such as aversion to bright light and conjunctiva swelling. The symptoms may be accompanied by gas in the abdomen.

3. Ruta

This is an effective remedy for allergic conjunctivitis where you may experience a constant feeling of something being stuck in the eye. There may also be swelling in the eyelids, redness and continuous watery discharge.

4. Pulsatilla

Pulsatilla is recommended if symptoms such as itchy eyes, yellowish discharge from the eyes and swelling of the eyelids are present. Hot and humid climatic conditions tend to aggravate this.

5. Apis Mel

Apis Mel is another homeopathic remedy that is used to treat eye allergies. Symptoms such as swelling of the eyes, burning sensation and intense pain in the eyes are very common. The symptoms are aggravated by hot weather conditions and direct exposure to the sun.

Eye Allergies - Know The Homeopathic Treatment For Them!

Ever noticed spots or strands that  float  into your line of vision. These are known as floaters. In most cases, they do not affect your vision, but can cause a lot of discomfort. Thus, in most cases they do not require treatment unless they affect your vision significantly. Floaters are more likely to stand out when looking at bright objects or something like a clear blue sky. Moving your eyes can shift the fluid in your eyes and move these floaters out of your line of sight.

Dust particles entering and irritating the eye should not be confused with floaters. Floaters can be described as flecks of a protein called collagen. These flecks can be seen when they are loosened from the back of the eye known as the vitreous. This can happen at any age but is more likely to affect people between the ages of 50 and 75. Being near sighted or suffering from cataract also increases your risk of seeing floaters. In rare cases, it can also be triggered by a disease in the eye, an injury to the eye, tumors or crystal deposits in the back of the eye.

Noticing the odd floater is not something to worry about. However, if you notice a sudden increase in the number and frequency of floaters in your eye, see flashes of light, have pain in the eyes or experience a loss of side vision, consult a doctor immediately. This could also be a sign of a more serious condition like a detached retina that requires immediate medical attention. Excessive floaters can be removed through a surgery known as a vitrectomy or laser vitreolysis. A vitrectomy involves the removal of vitreous gel from the middle of the eye and replacing it with silicone oil or a gas bubble. The surgery last 2 or 3 hours, but you may require an overnight stay in the hospital.

Laser vitreolysis is a more recent form of treatment for this condition. This pain free procedure involves the projection of a laser beam into the eye that focuses on large floaters to break them apart or vaporize them. This procedure can be performed as an outpatient and is considered safer than a vitrectomy. The form of treatment suited to a person will depend on a number of factors including their age, what the floaters look like, where they are located and the frequency of their appearance.

An inflammation resulting in the formation of a thin layer inside the eyelids or the white part of the eyeball is known as pink eye or conjunctivitis. This condition turns the eye ball into pinkish color, hence the name. Based on the severity of the infection, either one or both eyes get affected.

What are the common symptoms?

Medium to heavy swelling of the eye
Eye crusting after sleep
A burning sensation
Irritation, itching or blurred vision
Redness and increased sensitivity of the eye
Different kinds of conjunctivitis:

Allergic Conjunctivitis: This is the type of conjunctivitis that results from eye irritants such as animal dander, dust particles and pollen. This is not infectious in nature. Treatment prescribed by ophthalmologist includes eye drops and non-steroidal medications. It is advised to keep the eye moist till it gets cured.

Hand and eyes should not be in contact
Frequent change of pillow covers, towels and clothes
Swimming should be completely avoided
Spectacles in place of lens should be used until advised otherwise by a medical practitioner
Bacterial Conjunctivitis: This kind of conjunctivitis is caused by the streptococcal bacteria and has potential to cause real damage if proper medication is not taken on time. This is highly contagious. Prescription often includes antibiotic drop and ointments. The medication is prescribed for 2-3 weeks depending on the level of bacterial spread in the eye. It is very essential to complete the full course of medication to avoid recurrence. Prevention measures as stated above should be strictly followed.
Chemical conjunctivitis: Eye irritants such as chlorine cause this conjunctivitis. Frequent swimmers often get affected by this type of eye infection. Topical steroids are prescribed to cure this kind of infection. Immediate medical attention is required to avoid lasting injury to the eye.
