Retina Support: Photoreceptors
A number of inherited eye problems in the retina arise from mutations or dystropy of the photoreceptors - the rods and cones of the eyes or the retinal pigment epithelium (RPE).
- Cones are the photoreceptor cells which allow us to see fine details and color and comprise our central vision. Different types of cones absorb different wavelengths of light: blue (420nm), green (531nm), and red (588nm). This also gives us a clue as to why color blindness exists - one or more of these types of cones may function poorly.
- Rods allow us to see in low light conditions and provide peripheral vision.

The genetic code controls the protein-based molecules of pigment in the photoreceptor cells, called rhodopsin in the rods and iodpisin in the cones. Mutations which are primarily inherited can cause formations of deposits called bone "spicules" on the retina, or cause the photo receptors to deteriorate. 25% to 30% of photoreceptor defects are caused by mutations in the rhodopsin gene.
Some mutations of the photoreceptors begin in childhood, others may develop later in life.
- poor adaption in adjusting from light to dark or dark to light.
- poor night vision
- poor peripheral vision
- poor color detection
- errors in color vision in both red-green and blue-yellow ranges
Hundreds of different mutations of rods and cones have been identified, more than 100 of the mutations occurring in the rhodopsin molecule alone. For example:
- Rhodopsin overexpression
- Rhodopsin mutations such as RNA splice involving rhodopsin protein filiments or mutation of a single nucleotide in the genetic code, changing the protein
- Rhodopsin C-terminal mutations, wherein the protein tail mutates
- Rhodopsin molecule is engulfed by other cells
- Non retinal cell mutations.
- Deterioration of cone cells
- Deterioration of rod cells
Retinal photoreceptor mutations and dystrophy are considered incurable, however gene therapy shows some promise. Visual field testing is used to reveal abnormalities.
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. Even with genetically driven eye conditions, diet and lifestyle considerations may help slow down vision loss. Below are some recommendations:
- See our recommendations for nutrients, vitamins and supplements.
- See our recommendations for healthy vision 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. We offer our free general eye exercises and acupressure point booklet for overall eye health on our website (delivered as an email attachment after it is requested).
There is extensive research on nutrients such as vitamin A, 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 degeneration or retinitis pigmentosa may be applicable.
