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 is actually a freckle in your eye. Should you be worried? This specific 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) is actually a pigmented, well demarcated dark spot inside the back of your eye on your retina. Though size varies, This specific is actually convenient to think of This specific as about equivalent to the top of an eraser on a pencil. This specific is actually an accumulation of increases in pigment inside cells of the retinal pigment epithelium cell layer. This specific is actually hypertrophy, or an increase inside size yet not the number of cells. The blood vessels underneath This specific atrophy also which results in a little blind spot which you are not capable of perceiving. While there are often modifications over time; This specific is actually 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 is actually you can't observe This specific for any modifications 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 through 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 various other 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 inside back of the eye in which look like little bear footprints. They frequently occur in conjunction having a condition called familial polyps  as well as require further testing for colon as well as rectal cancer. This specific can be due to a dominant gene in which is actually 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 This specific is actually 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 through injury or infections inside 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 inside number of retinal pigment epithelial cells. The primary  concern in This specific case is actually to monitor the condition in which caused This specific. If This specific is actually an infection in one of the layers of the eye This specific could recur at a later date.
A choroid nevus is actually indeed like a nevus (freckle) yet This specific is actually occurring inside 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 inside choroid. These types of cells are found in our skin as well as in parts of the eye. The retina does not hold the same type of pigment cells, This specific has pigmented epithelium cells instead. A choroid nevus is actually usually flat, yet does appear more similar to melanomas inside 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 This specific is actually 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 is actually the only technique in which allows eye doctors to adequately detect most of theses spots. Although This specific can be mildly uncomfortable causing light sensitivity as well as mild dry eyes, This specific should be done by you optometrist. Frequently patients have not had their eyes routinely dilated inside past so when your optometrist finds a brand new spot or freckle in your eye This specific may have been there unchanged for years. You can be reassured in knowing  in which the large majority of the time This specific is actually completely innocuous as well as only needs to be rechecked once every year for any modifications. In areas with large amounts of UV exposure like Northern Colorado, sun wear with UV protection can help reduce the risk of melanomas. There is actually some controversy over UV exposure as well as cancer, as well as some suggestions in which vitamin D may reduce certain type of tumors as well as the colon cancer seen associated with bear tracks. inside future, sun wear as well as moderate exposure to UV could become the recommendation.
