What is congenital ocular melanocytosis?
Congenital ocular melanocytosis is an abnormality characterized by diffuse brown melanocytic hyperplasia in the sclera and uvea. In congenital oculodermal melanocytosis (nevus of Ota), there is cutaneous hyperpigmentation in the distribution of the trigeminal nerve in addition to ocular involvement.
What causes ocular melanocytosis?
The disease is caused by an increase of melanocytes in the iris, choroid, and surrounding structures. Overproduction of pigment by these cells can block the trabecular meshwork through which fluid drains from the eye. The increased fluid in the eye leads to increased pressure, which can lead to glaucoma.
How common is ocular melanocytosis?
Petersen-Jones Laboratory. Ocular melanosis (OM), also known as ocular melanocytosis or melanosis oculi, is a congenital disease of the eye, which affects approximately 1 in every 5,000 people, and is a risk factor for uveal melanoma.
Is ocular melanocytosis rare?
Oculodermal melanocytosis (ODM) is a rare disease, which is characterized by hyperpigmentation of facial skin and several parts of the eye, such as the sclera, conjunctiva, cornea, iris, ciliary body, and choroid.
What are the symptoms of ocular melanoma?
Symptoms
- A sensation of flashes or specks of dust in your vision (floaters)
- A growing dark spot on the iris.
- A change in the shape of the dark circle (pupil) at the center of your eye.
- Poor or blurry vision in one eye.
- Loss of peripheral vision.
How do you get rid of ocular Melanocytosis?
Treatment of ocular melanoma is based on what part of the eye is affected and whether it has metastasized to other parts of the body. Surgery is one method for treating melanoma of the eye. Removal of the eye (enucleation) may be necessary in some cases of large tumors when other treatment methods are not suitable.
Is ocular Melanosis harmful?
In addition, people with abnormal skin pigmentation involving the eyelids and adjacent tissues and increased pigmentation on their uvea — known as ocular melanocytosis — also have an increased risk of developing eye melanoma.
How is ocular Melanosis treated?
Conjunctival PAM is often precancerous and leads to life-threatening malignant melanoma. Conjunctival PAM should be treated with surgery, cryotherapy, or sometimes chemotherapy eye-drops to eradicate it before melanoma develops.
How long can you live with ocular melanoma?

How do you treat scleral Melanocytosis?
Therapeutic Principles. In Asian individuals scleral melanocytosis is a benign condition and no treatment is necessary. In Caucasian individuals, scleral melanocytosis is associated with an increased risk of uveal melanoma, and lifetime ophthalmologic monitoring is warranted.
Why does my baby have grey spots in her eyes?

How is ocular Melanosis treatment?
Options may include: Surgery to remove the melanoma and a small area of healthy tissue. Surgery to remove the melanoma and a band of healthy tissue that surrounds it may be an option for treating small melanomas. Surgery to remove the entire eye (enucleation).
Is there a cure for ocular melanoma?
These rare cancers can be treated with either surgical removal of the tumor, if it is small enough, or radiation therapy. In more advanced cases or if there is serious eye damage, enucleation (removal of the eyeball) may be needed.
Is scleral Melanocytosis permanent?
Oculomucodermal melanocytosis (Nevus of Ota) is a benign dermal melanocytosis, that results in hyperpigmentation of the sclera and ipsilateral face. Presenting at birth or by adolescence, these lesions tend to remain unchanged throughout life but can darken overtime due to sun exposure.
Is scleral Melanocytosis normal?
Scleral melanocytosis is a common pediatric condition that becomes prominent with increasing age and usually is bilateral. The benign condition is more common in persons of Asian descent. The condition characteristically features black or gray-blue pigmentation in the scleral tissue.
