Thank you for your reply. I understand your anxiety and worry, but you do not need to worry.
The grey shadows or sometimes brown/dark in the back of the eye is generally a non-harmful mole or nevus
in the eyes. It is a common finding is a significant percentage of the population. They do not (rarely) turn into a problem like cancer, and do not affect vision. However, it is recommended that you make effort to wear good UV protective sunglasses
. Even so direct exposure to sunlight for decades will be necessary to affect it. Depending on where the gray shadow or mole is located, the type, size and location will help the doctor classify and monitor it in the future.
The evaluation by the eye doctor could includes the following:
1. Determine the location, size, exact color, shape or any other characteristics
2. Perform at complete eye examination with dilation to ensure no other sign of abnormality.
3. Take picture of the gray shadow or nevus/mole to allow the future comparison of the size and any change in shape, color
4. The doctor may perform ultrasound
and OCT if necessary to better understand the characteristics of the gray shadow or mole.
In general, the gray shadow or mole which are located at the back of the eye, it are either a choroidal nevus or congenital retinal nevus. They are common, and not harmful. The reason the optician is referring you to the ophthalmologist
is due to the established medical protocol - which required that eye mole or gray shadow be evaluated by the trained eye specialist (Ophthalmological retina specialist) to record the initial characteristics of the gray shadow or mole. The optician as you know is not officially trained nor certified to evaluate and treat such eye conditions
, but only certified to fit glasses. However, with experience the optician can at least recognize moles because eye moles are very common among the population.
So, I suggest that you do not worry - you mostly likely have the regular common mole. Please, keep your appointment with the eye doctor so that the gray shadow or mole can be properly evaluated and size noted.
