Information on diet, nutrition & self-help options

Rod cone dystrophy is expressed as a number of inherited eye problems, due to the common cause of malfunctioning of the cone and rod photoreceptors. These photoreceptors change light into electric nerve messages that transfer to our brain via our optic nerve. Cones are the photoreceptor cells which allow us to see fine details and color and comprise our central vision. Rods are for low light vision and permit night and peripheral vision. The malfunctioning photoreceptor cells be problematic starting in childhood, or may lose their functionality with time.

Self Help

Since we consider most eye conditions to be a reflection of the health of the whole body, lifestyle choices and diet can play a major factor in getting and maintaining good vision. Below are some recommendations:

Supplementation with research-proven nutrients and eyedrops that have been found to be helpful to protect vision.
See our recommendations for healthy eyes for details.
Eye exercises can help to bring energy and blood to the eyes, thereby helping to drain away toxins or congestion to the eyes. These are free general eye exercises and acupressure points for overall eye health.
It is possible to slow down vision loss and possibly maintain healthy vision:

Energy moving modalities such as acupuncture and microcurrent stimulation may be helpful.
See all retinal support vitamins & supplements
Rod and cone photoreceptors are good at seeing different things. Here are some examples:

Rods are good at ‘seeing’:

things that move but only in black and white
seeing in the dark
seeing things on the sides of us (peripheral vision)
Cones are good at ‘seeing’:

things that are still
fine details of thing in daylight
objects in color
things in fine detail including reading, looking at photographs and recognizing faces
Symptoms

gradual loss of night vision
gradual loss of peripheral vision
sensitivity to bright light
vision is best at dusk
errors in color vision in both red-green and blue-yellow ranges
Young children with Rod-Cone Dystrophy may develop:

Fast ‘to and fro’ movements of the eyes. This is referred to Nystagmus.
‘Roving’ eye movements where the eyes appear to slowly wander around not fixing and staying still on any objects.
‘Eye Poking’ where the child touches their eyes with their fingers.
Parents will often notice these signs by the way the child acts.

Causes

There are many different causes of Rod-Cone Dystrophies. Often one does not know why a child has a Rod-Cone Dystrophy. When no cause can be identified this is called Idiopathic.

Most Rod-Cone Dystrophies are genetically based and result from “misprints” in a child’s genes, and are typically carried forward from the parents’ genes although sometimes by chance a new mistake occurs in the child’s genes and the parents’ genes are normal.

Conventional Treatment

There is no good conventional way to stop the sight loss in Rod-Cone Dystrophy.

Related Conditions

Other eye conditions where the rod and cone photoreceptor cells do not work properly include: Leber’s Amaurosis, Retinitis Pigmentosa, Usher’s Syndrome and Batten’s Disease.

Synonyms: Retinal Cone Degeneration, Retinal Cone-Rod Dystrophy, Cone Rod Dystrophy, Combined Cone-Rod Degeneration, Cone Rod Degeneration, Progressive Cone Rod Dystrophy, Retinal Cone Dystrophy, Retinal Cone Rod Dystrophy

Research

Though there are no specific studies on nutrients and this particular condition, there is extensive research on nutrients such as lutein, zeaxanthin and bilberry among others that have been shown to be essential for the health of the rod-cone structures. Based on these studies, Dr. Grossman has selected specific nutrients and products to help support this part of the eye and overall eye health. Some research on macular degenerationor retinitis pigmentosa may be applicable.
