An Eye for an Eye gives the whole world sight

Today I visited my eye doctor; he said it might take approximately 6 more months for me to get my complete vision back in my right eye. It’s becoming difficult to see with my left eye.

19-Mar’12, 4:30am

I woke up suddenly because I had a dream where it was all dark and I couldn’t see anything. It startled and jolted me out of my sleep. I’m worried about my left eye, the vision is deteriorating. The doctor says it’s some corneal problem. Only replacing the cornea will bring back my vision. A similar thing happened in my right eye and I lost vision.

It all started 2 years ago. I was a happy-go-lucky person and enjoyed my school days. One day I was coming back from school and suddenly there was an explosion from a road side shop. Dirt and some sharp objects hit my face and few of them injured both my eyes.

I was taken to the hospital and treated. After a month I was left with partial vision in my left eye. The vision in my right eye was completely gone, due to an infection following the injury. Doctors gave me hope saying that replacing the cornea will bring back the vision in my right eye. But they also said that the vision in my left eye will gradually reduce with time. I rejoiced that the cornea can be replaced, but when I came to know that I have to wait for it, I wondered how long it would take to receive one.

25-Mar’12, 9:25pm

I inquired about eye donation. That’s when I learnt how it all works – they take the cornea of a person who has pledged his or her eyes. This can be done only after their death. I felt sad I have to wait for someone to die. It is sad that so many people die every day and their eyes cannot give some one sight if they haven’t pledged them.

15-Apr’12, 6:15am

Today I have to visit my doctor. I will know precisely when they will operate on my right eye. I’m tense and hope they don’t delay it further.

15-Apr’12, 9:45pm

The doctor said they would probably operate on my right eye in the first week of July. Now they receive more eye donations from people, as they are more aware of the need. Once I regain my vision, I will contribute some of my time and work for building awareness. Millions of people are blind and are waiting to regain their vision. If only everyone would pledge their eyes, there will not be anyone missing out on the beauty of nature and their independence.

30-Apr’12, 11:30pm

Now it’s become difficult for me read or write. I read one or two lines and my left eye starts paining.

15-May’12, 1:00pm

I visited my doctor today. The vision in my left eye has completely deteriorated.

25-Jun’12, 11:00am

I can’t resist writing. I can barely see my diary. I have to take my mother’s help. I’m tense, yet I look forward to the days after my surgery. I hope to read and write well and also be able to do everything on my own. I want to study and make a career, while leading a normal life, just as the others.

Eye Donation

28 Oct

The greatest pleasure comes from giving sight to a blind person. Imagine the world of a person who cannot see. It’s usually a world without hope. But for some of these carnally blind persons, there is still hope. And this hope comes eye donation, since what’s being donated is useless to the donor after death.

You have the power to bring immense joy by giving sight to the blind.

Why:

In India, we have an estimated 4.6 million people with corneal blindness that is curable through corneal transplant that’s possible by eye donation. More than 90% of the corneal transplants are carried out successfully and help restore vision in people with corneal blindness. Corneal transplant in infants born with cloudy cornea can make a massive difference to their lives.

Corneal Blindness:

What is Corneal Blindness? Cornea is the transparent skin cover at the front of the eye. It is like the windscreen of a car; if damaged, vision is lost.

How:

By replacing the damaged cornea with a good cornea, these carnally blind persons can gain vision and see again.

Causes:

Eye infections, eye injuries and malnutrition, if not attended to in time, cause blindness. A very large percentage of carnally blind are children belonging to poor families.

Eye donation and restoration of sight through corneal transplant is an exciting combination of selfless charity and the miracle of medical technology.

Facts about eye donation:

Eyes should be donated within 6-8 hours of death.
Anyone can be a donor, irrespective of age, sex, blood-group or religion.
Total removal time is about 15-20 minutes.
Spectacle wearers, hypertensive and diabetics can also donate their eyes.
There is no disfigurement caused to the donor’s face.
Eyes can be donated even if the deceased had not formally pledged their eyes during their lifetime.
The eye bank team will immediately reach the donor’s home to collect the eyes and this service is free.
Eyes are never bought or sold.
All religions endorse eye donation. 

Myths about eye donation:

Face/body will be disfigured.
Will be born blind in the next birth.
Will not be able to see God. 

Contraindications for corneal transplantation:

Active Viral Hepatitis
Acquired Immuno Deficiency Syndrome (AIDS) or HIV
Active Viral Encephalitis or Encephalitis of unknown origin
Rabies
Active Septicemia
Retinoblastoma
Leukemia and Lymphoma 

Conclusions:

Pledge to donate your eyes. Make it your family’s tradition.
Motivate and educate others about eye donation.
Motivate the next of kin of the deceased to donate their eyes.

Types of Blindness

19 Oct

Blindness is the condition where one lacks visual perception due to physiological or neurological factors. 

Complete Blindness:

Complete or Total Blindness is the complete lack of form and visual light perception and is clinically recorded as NLP, an abbreviation for No Light Perception. Blindness is frequently used to describe severe visual impairment with residual vision.

Complete blindness causes complete darkness in the affected person’s sight. There is no perception of light, color, shape or movement.

Complete blindness, though rare, can be caused by any type of retinal detachment or damage to the optic nerve or a disease that attacks the central nervous system, such as brain tumor or a stroke.

Legal Blindness

Legal blindness is defined as having equal to or worse than a 20/200 visual acuity in the better eye with the best correction possible.

Legal blindness typically indicates that the central vision is lost while the peripheral vision is usually intact. Patients are usually able to function to a certain extent.

This means that a legally blind individual would have to stand 20 feet (6.1 m) from an object to see it, with corrective lenses and with the same degree of clarity as a normal sighted person could from 200 feet (61 m). People with average acuity, who nonetheless have a visual field of less than 20 degrees (the norm being 180 degrees), are also classified as being legally blind. 

Colour Blindness

People who suffer from Colour blindness, also called dyschromatopsia, are unable to distinguish between certain colors.

This type of blindness usually affects men and the most common form of color blindness is red-green color blindness. Color blindness is almost always present since birth and is usually caused by the presence of a defective gene in the X chromosome. 

Night Blindness

Night blindness is vision impairment that occurs at night or when the surrounding light is dim.

It does not generally result in a complete lack of vision, but significantly impairs vision. People with night blindness often have difficulty driving at night or seeing stars. These factors include cataracts, birth defects, Vitamin A deficiency or a retinal disease called Retinitis Pigmentosa.

Signs of blindness in babies

Blindness in children is extremely rare and is very difficult to detect, especially in newborns.

Premature babies are more vulnerable to blindness. If a baby is born blind, it’s usually because of abnormalities during development, a hereditary disease, injury at birth or congenital infection that caused the damage.
