ANSWER: Prashant,

Great question. You made me have to dig around a little to be sure of my answer. The answer is yes and the condition is called Achromatopsia. It affects 1 in 40,000 people, is genetic in origin, and is found in places of the world where the marriage of biologically related people have children.

In the retina there are rods and cones that are receptors of the photons of light as they come to focus on the back of the eye. There are three types of cones, red, green, and blue, and they perceive color while the rods see without color perception and are what allow for seeing in low light. A child born without functioning cones is unable to perceive any color. They see in grey scale. From black to white with no other colors.

QUESTION: Dear Robert

Thanks.

Can these be the line of treatment for Color Blindness and Achromatopsia?.

1  Eyes surgeries replacing the defective eyes with the donor eyes from the eye Banks.

2 Brain Surgery of the thalamus or Cerebral Cortex parts of the Brain.

3 Gene therapy.

Thanks & Regards,
Prashant S Akerkar

Answer
Prashant,

I am going out on a limb here. The question, for practical purposes, is way outside of my scope of understanding. But, if I were going to give it my best guess I would think, assuming there is no other damage to the eye, or the retina and its connection, via the optic nerve to the brain, some sort of therapy that could introduce cones, whether mechanical or perhaps stem cell in origin, would seem to me to be the easiest way to go about addressing the condition.

No surgery exists whereby a donor eye can be implanted into another. The eyeballs connection to the optic nerve bundle which is connected directly to the brain, I believe, is the main reason for this not being a viable way to address the condition. Corneas are harvested but they are the clear part of the eye that covers the iris, or colored part of the eye.

The problem is not in the brain but in the retina. The retina is at the back of the eyeball on the inside.


These are guesses. An ophthalmologist or someone in research, stem cell, or neurology perhaps, could give you much better understanding of where we are and what the future holds for the treatment of this condition.

Contact lens Care: Tips and suggestions that I have used to teach first time contact lens wearers, even pre-teen and adolescent children, to quickly give them the skills and confidence to put in and remove their contact lenses. Tips on getting them in fast in the morning and out quickly at night without having that itchy feeling when you remove them. I can explain to you the makeup of the tear layer and how it can directly affect the comfort of your contacts based on little thing like computer use, heating and air in the car and office, that cloudy afternoon vision or dry feeling later in the day. Lens Recommendation: Based on your prescription I can advise what lens materials and designs are best suited to your needs and which ones to avoid as well as direction on frames designs that would complement the selection. Proper Frame Adjustment: I can help identify the problems associated with painful glasses that pinch, or squeeze. I can help you avoid getting a pair of glasses that constantly slide down your nose no matter how many times you get them adjusted. I can teach you what to look for in a frame that is right for you. I can explain how to look for a good quality frame that is not the most expensive in the room. I cannot diagnosis disease, prescribe or offer price specific advice or information.
