A choroidal nevus (plural: nevi) is typically a darkly pigmented lesion found in the back of the eye. It is similar to a freckle or mole found on the skin and arises from the pigment-containing cells in the choroid, the layer of the eye just under the white outer wall (sclera). (Figures 1 and 2).
The estimated prevalence of choroidal nevi in the United States has been reported to be 5% with significant variation by race: 5.6% in White individuals, 2.7% in Hispanic populations, 0.6% in Black individuals. The estimated prevalence of choroidal nevi in Asian populations has been reported at 1.8% to 2.9%.
Some nevi can have areas that appear nonpigmented or amelanotic, and others are mostly amelanotic and appear yellowish rather than brown ( Figure 3 ). Nevi can also develop overlying deposits known as drusen, as well as degenerative changes of the overlying retinal pigment epithelium (RPE) seen as mottled pigmentation or fibrosis ( Figure 4 ).
Nevi without any clinical risk features may be examined annually. However, those with one or more risk factors should be examined approximately every 4 to 6 months. Evaluation of these lesions would include a dilated retinal examination and possibly ultrasonography, fundus photography, and OCT.
Many nevi can be identified by their appearance alone on examination of the retina. This includes a brown to slate gray coloration with distinct but mildly blurred margins where the color of the nevus blends into the normal retina.
Most choroidal nevi remain benign (non-cancerous) and have no symptoms. However, occasionally, a nevus can transform into uveal melanoma. The rate of choroidal nevi transforming into melanoma is estimated at approximately 1 in 9000 per year. When a nevus shows significant growth over a relatively short period of time (such as 1 year), it is presumed to have become malignant (cancerous).
Most commonly, a choroidal nevus does not cause any symptoms and is found on routine eye exam. However, sometimes nevi under the center of the retina (the macula) can cause blurred vision. When a nevus causes degeneration or dysfunction of the overlying RPE, fluid may accumulate under the retina or abnormal blood vessels ( choroidal neovascularization) may develop and bleed or leak fluid.
Vitreous degeneration, unspecified eye H43. 819 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2020 edition of ICD-10-CM H43.
The ICD - 10 -CM code D31. 32 might also be used to specify conditions or terms like benign neoplasm of choroid or benign neoplasm of left choroid or nevus of choroid of left eye.
Management of a choroidal nevus is determined by its risk of transforming into a choroidal melanoma.
Choroidal nevi are benign melanocytic lesions of the posterior uvea. In the United States, their prevalence ranges from 4.6 percent to 7.9 percent in Caucasians. 1 By comparison, choroidal melanoma is rare, manifesting in approximately six in 1 million Caucasian individuals.
In contrast, choroidal melanomas are more likely to show signs of activity such as relatively indiscrete margins, irregular or oblong configuration, overlying subretinal fluid and orange pigment, and abruptly elevated edges. Documentation of growth. Most authorities agree that documentation of growth over a relatively short period of time, ...
Over time, choroidal nevi display features such as overlying drusen as well as retinal pigment epithelial atrophy, hyperplasia or fibrous metaplasia.
In addition, making the correct diagnosis of choroidal nevi in a timely fashion protects patients against the visually damaging effects of unnecessary treatment.
By lesion size. Some clinicians suggest observation for lesions smaller than 2 mm; lesions larger than 2 mm but smaller than 2.5 mm may be managed based on clinical risk factors, with either close observation or immediate treatment.
Choroidal nevi rarely evolve into malignant melanoma; the annual rate of malignant transformation is estimated to be 1 in 8,845. 1 The rate of transformation increases with age; it has been estimated that by age 80, the risk for malignant transformation of a choroidal nevus is 0.78 percent. 7. Although nevus thickness has been reported to be ...
DEFINITION. Choroidal nevus is a benign tumor caused by proliferation of the melanocytes normally found in the uvea. The lesion is characterized by the following clinical features: Usually no change in visual acuity. Clearly defined margins. Flat or slightly elevated. Stable in size over time.
Patients with one or two risk factors should be examined every six months.
The treatment of a benign choroidal nevus is determined by its risk of malignant transformation into a choroid al melanoma. It is not common for a choroidal nevus to transform into a malignant melanoma. The annual rate of malignant transformation is estimated to be 1 in 8,845.
The symptoms of choroidal nevus vary from no symptoms to severe visual impairment. Patients with a large nevus may have mild visual impairment secondary to retinal complications. Patients with a choroidal nevus may present with any of the following abnormal clinical signs or symptoms: None.
