Department of Ophthalmology, Ramathibodi Hospital, Mahidol University, Bangkok, Thailand.

We examined 194 patients with oculodermal melanocytosis. Dermal involvement alone was present in 67 (34.5%) patients, while 12 (6.2%) had only ocular involvement. The remaining 115 (59.3%) patients had both ocular and dermal pigmentation. Dermal hyperpigmentation in the combined distribution of the ophthalmic and maxillary divisions of the trigeminal nerve and hyperpigmentation of the nasal or buccal mucosa were closely associated with ocular involvement. Ocular hyperpigmentation most commonly involved the episclera. Associated ocular findings included elevated intraocular pressure with or without glaucoma (10.3%), uveitis (2.6%), cataract (1%), asymmetric cupping of the optic nerve head unassociated with glaucoma (9.8%), and orbital melanoma (0.5%). The most serious complication of oculodermal melanocytosis is malignant transformation, while glaucoma appears to be the more common one. Patients with oculodermal melanocytosis and ocular hyperpigmentation should be followed up at regular intervals for the development of either of these complications.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D008297	Male		Males
D008544	Melanocytes	Mammalian pigment cells that produce MELANINS, pigments found mainly in the EPIDERMIS, but also in the eyes and the hair, by a process called melanogenesis. Coloration can be altered by the number of melanocytes or the amount of pigment produced and stored in the organelles called MELANOSOMES. The large non-mammalian melanin-containing cells are called MELANOPHORES.	Melanocyte

D009297	Nasal Mucosa	The mucous lining of the NASAL CAVITY, including lining of the nostril (vestibule) and the OLFACTORY MUCOSA. Nasal mucosa consists of ciliated cells, GOBLET CELLS, brush cells, small granule cells, basal cells (STEM CELLS) and glands containing both mucous and serous cells.
