Title : Eye Doctors Explanation of Why Freckles as well as Spots in Your Eyes Need Monitoring With Vision Exams
So you have been told by your eye doctor there will be a freckle in your eye. Should you be worried? which could be several things yet the most likely are choroid nevus or benign choroid melanoma congenital hypertrophy of the retinal pigmented epithelium. Both conditions are usually benign as well as not a serious problem. They both need to be monitored to make sure they are not malignant melanomas.
Congenital hypertrophy of the retinal pigmented epithelium (also known as halo nevus) will be a pigmented, well demarcated dark spot inside the back of your eye on your retina. Though size varies, which will be convenient to think of which as about equivalent to the top of an eraser on a pencil. which will be an accumulation of increases in pigment within the cells of the retinal pigment epithelium cell layer. which will be hypertrophy, or an increase within the size yet not the number of cells. The blood vessels underneath which atrophy also which results in a smaller blind spot which you are not capable of perceiving. While there are often adjustments over time; which will be mostly a stable, inconsequential change as well as congenital hypertrophy of the retinal pigmented epithelium can be thought of like a freckle on your skin. The difference will be you can't observe which for any adjustments like you can a spot on your hand, so serious conditions can advance past the treatable stages. On rare occasions a halo nevus can change by a normally flat surface as well as develop elevated nodules. The formation of these tumors are very rare yet something eye doctors do check for on an annual basis. Usually no further tests are required different than eye exams with your eyes dilated in 3-6 months after first observation, then annually there after.
Congenital hypertrophy of the retinal pigmented epithelium also occurs in a form called "Bear Tracks." Bear tracks are multiple dark spots within the back of the eye which look like little bear footprints. They frequently occur in conjunction that has a condition called familial polyps as well as require further testing for colon as well as rectal cancer. which can be due to a dominant gene which will be often seen to run in families as an predisposition to colon cancer. Bear Tracks may be seen years before the cancer occurs so they may be a valuable preventative sign to your optometrist. Bear tracks may require a referral to another specialist for further evaluation. Not every patient with Bear Tracks will get colon cancer, yet which will be more likely if they are large, present in both eyes, as well as there are more than 3 or 4 spots in each eye. Isolated single congenital hypertrophy of the retinal pigmented epithelium spots are not associated with Familial polyps or an increased risk of colon cancer.
Trauma to the retina whether by injury or infections within the eye can cause dark spots similar to congenital hypertrophy of the retinal pigmented epithelium yet they are irregular in shape. They are due to an actual increase within the number of retinal pigment epithelial cells. The primary concern in which case will be to monitor the condition which caused which. If which will be an infection in one of the layers of the eye which could recur at a later date.
A choroid nevus will be indeed like a nevus (freckle) yet which will be occurring within the choroid, the level below the retina which supplies circulation to the retinal tissue. These appear as round, gray, usually flat spots as well as are very common occurring in up to 30% of the population. They are also referred to as benign choroid melanomas, though they are not true melanomas. They are due to an increase of pigment cells within the choroid. These types of cells are found in our skin as well as in parts of the eye. The retina does not possess the same type of pigment cells, which has pigmented epithelium cells instead. A choroid nevus will be usually flat, yet does appear more similar to melanomas within the choroid due to being located at the same level below the retina. They require closer observation as well as sometimes further testing to make sure they are benign spots. Any nevus can undergo transformation to a melanoma yet which will be very rare.
Testing to diagnose any brand new spot observed can include ongoing observation, optical coherence tomography techniques of imaging the layers of the retina, digital imaging pictures, as well as dye imaging of the retina. A dilated exam of the inside of your eye annually will be the only technique which allows eye doctors to adequately detect most of theses spots. Although which can be mildly uncomfortable causing light sensitivity as well as mild dry eyes, which should be done by you optometrist. Frequently patients have not had their eyes routinely dilated within the past so when your optometrist finds a brand new spot or freckle in your eye which may have been there unchanged for years. You can be reassured in knowing which the large majority of the time which will be completely innocuous as well as only needs to be rechecked once every year for any adjustments. In areas with large amounts of UV exposure like Northern Colorado, sun wear with UV protection can help reduce the risk of melanomas. There will be some controversy over UV exposure as well as cancer, as well as some suggestions which vitamin D may reduce certain type of tumors as well as the colon cancer seen associated with bear tracks. within the future, sun wear as well as moderate exposure to UV could become the recommendation.
