There is often a halo of depigmentation just inside the outer edge of these lesions ( Figure 12.01 E and F). However, CHRPE in macula and juxtapapillary location are rare. A CHRPE may occur anywhere in the fundus. Many patients are unaware that IBD has a risk of eye complications and, therefore, patient education is vital. They are usually solitary but may be multiple and grouped in a pattern suggesting animal tracks ( Figure 12.01 A). Clinical manifestations include blurred vision, teary, burning or itchy eyes, ocular pain, photophobia, conjunctival or scleral hyperemia, loss of visual acuity, and possible blindness. Both solitary CHRPE and its multifocal variant. They generally involve the peripheral retina, similar to that of bear track grouped pigmentation. We review ocular pathology in IBD to alert clinicians to the diverse, at times confusing, spectrum of eye disorders associated with these diseases. This appearance resembles an animal paw or footprint, and thus they are commonly referred to as bear tracks. Congenital grouped albinotic retinal pigment epithelial spots (CGARPES), or polar bear tracks, is a rare anomaly characterized by multiple grouped, white, variably sized, albinotic spots. Clinicians must be aware of the spectrum of ocular symptoms and know that these complaints may precede a diagnosis of ulcerative colitis (UC) or Crohn's disease (CD). Evaluation of the eye should be a routine component in the care of patients with IBD. Ocular complaints are often nonspecific clinical relevance may not be appreciated by patient or physician and, thus, be misdiagnosed. Several tumors and pseudotumors can arise from the iris pigment epithelium (IPE), ciliary pigment epithelium (CPE), and retinal pigment epithelium (RPE), including cysts of the IPE, solitary congenital hypertrophy of the RPE (CHRPE), multifocal CHRPE ('bear tracks'), congenital simple hamartoma of the RPE, combined hamartoma of the. Several tumors and pseudotumors can arise from the iris pigment epithelium (IPE), ciliary pigment epithelium (CPE), and retinal pigment epithelium (RPE), including cysts of the IPE, solitary congenital hypertrophy of the RPE (CHRPE), multifocal CHRPE (bear tracks), congenital simple hamartoma of the RPE, combined hamartoma of the retina and RP. Ocular complications are infrequent, occurring in less than 10% of cases, but can be associated with significant morbidity, including blindness. Known to be associated with other systemic findings such as familial adenomatous polyposis and Gardner's syndrome (intestinal polyposis, hamartoma of the skeleton, and multiple soft tissue tumors).Extraintestinal manifestations of inflammatory bowel disease (IBD) occur in one third of patients.Therefore, if your eye care specialist has told you that you have CHPRE( pronounced CHER PEE), it is reasonable to tell your primary care physician or gastroenterologist (if you have one) so that he or she may recommend the frequency of colon. It is commonly seen in patients with familial adenomatous polyposis (FAP). 10.3928/23258160-20200326-05 Abstract The terms 'congenital grouped albinotic spots' (CGAS) and 'polar bear tracks' refer to a rare, benign retinal disorder of unknown etiology characterized by multiple, predominantly unilateral, variably sized, well-circumscribed, flat white retinal spots organized in groups. The condition is benign, although it may cause small visual field defects. The bear tracks (dark blotches) are due to congenital hypertrophy of the retinal pigment epithelium (CHRPE). They are usually solitary but may be multiple and grouped in a pattern suggesting animal tracks ( Figure 12.01 A). Differential diagnosis include: choroidal melanomas, choroidal nevi, melanocytomas of the choroids, hyperplasia of the RPE, post-hemorrhage hemosiderin deposits. This is a case of congenital hypertrophy of the retinal pigment epithelium, bear-tracks. Bear tracks on the retina of the eye, ophthalmoscope image.Fluorescein angiography demonstrates blocked choroidal fluorescence by the hypertrophied RPE and no leakage of dye.Generally located in the peripheral but may occasionally in the peripapillary region.The condition is benign, although it may cause. Multiple areas of grouped CHRPE simulating the animal foot-print are also called "bear tracks". The bear tracks (dark blotches) are due to congenital hypertrophy of the retinal pigment epithelium (CHRPE).Depigmented or hypopigmented punched-out lacunae or fenestration lesions may be evident within larger lesions.May be encircled by hyper- or hypo-pigmented halo.Well-demarcated, round, solitary or multiple gray-brown or black lesions which have flat or scalloped margins. 9.1.1Eye Abnormalities Systemic Abnormalities Complications and Prognosis Gardner Syndrome ICD 10 code: D12.Benign pigmented fundus lesions that commonly discovered during routine eye examination.
