reversal of laser induced hypopigmentation with a narrow band uv b light source in a patient with skin type vi
Dermatologic Surgery, 2008Co-Authors: Anetta E Reszko, Sean A Sukal, Roy G GeronemusAbstract:nevus of Ota (nevus fuscoceruleus ophthalmomaxillaris) is a benign dermal melanocytic hematoma clinically appearing as a bluish-brown discoloration in the ophthalmic and/or maxillary branches of the trigeminal nerve. The condition first described by Ota and Tanino occurs predominantly in Asians with estimated frequency of 0.014% to 0.034%, but can be found in other ethnicities. Historical therapies for nevus of Ota include surgery, dermabrasion, electrodesiccation, skin grafting, and cryotherapy and are all associated with a significant risk of dyschromia and scarring.

analysis of 602 chinese cases of nevus of Ota and the treatment results treated by q switched alexandrite laser
Dermatologic Surgery, 2007Co-Authors: Hongwei Wang, Gangkui Zhang, Guotiao Jiang, Jiabi WangAbstract:BACKGROUND nevus of Ota is a congenital or acquired pigmentary disorder of the skin and mucous membranes, which are areas innervated by the first and second branches of the trigeminal nerve. nevus of Ota is very common in Asia. nevus of Ota was effectively treated with Q-switched alexandrite (755 nm) laser, but no detailed report existed on many Chinese cases treated with Q-switched alexandrite laser. OBJECTIVE The objective was to gauge clinical and treatment data and material statistics for 602 cases of nevus of Ota and analyze its pathogenic mechanism and therapeutic results. METHODS A tOtal of 602 cases of clinical data on nevus of Ota were collected by means of clinical registration, photo verification, and telephone inquiry or correspondence. CONCLUSIONS There are some differences in sex, age, and local regions in nevus of Ota. nevus of Ota can combine with other diseases. The treatment of nevus of Ota by a Q-switched alexandrite laser is safe and effective. Additional treatment will achieve good results. The results correlate to the eyelids and Tanino's classification.

Phakomatosis Pigmentovascularis Associated With Sturge-Weber Syndrome, Ota nevus, and Congenital Glaucoma.
Medicine, 2015Co-Authors: Yangfan Yang, Xiujuan Guo, Xiao'an LiuAbstract:Phakomatosis pigmentovascularis (PPV) is a rare congenital malformation syndrome that is characterized by a combination of capillary abnormalities and dermal melanocytosis. We describe 3 cases of PPV combined with bilateral Sturge–Weber syndrome (SWS), Ota nevus, and congenital glaucoma. Case 1 was a 2-year-old boy. Facial port-wine stains distributed along the 3 branches of his trigeminal nerves, which suggested the existence of SWS. Gray-blue patches were spread over the frontal and temporal areas of bilateral face, waist, buttocks, and thigh. Bilateral triangular alopecia was found on the temporal scalp. The diagnosis of Ota nevus was made by the bilateral scleral malanocystosis. Increased intraocular pressure, enlarged cornea, and pathologic optic disc cupping supported the diagnoses of infantile bilateral glaucoma. Case 2 was a 4-year-old boy. Port-wine stains were found on the face along the 3 branches of the trigeminal nerve and distributed along the trunk, arms, and legs. Mongolian spots spread over his frontal and temporal areas of the bilateral face, waist, buttocks, thigh, abdomen, and back. Infantile glaucoma was found in both eyes. Ota nevus were found in the both eyes. Optic coherent tomography (OCT) scans revealed increased thickness of choroid. Case 3 was a 5-year-old boy. Besides Ota nevus and infantile glaucoma in both eyes, color Doppler ultrasonography showed choroidal hemagioma. OCT scan showed increased choroidal thickness. The bilateral triangular alopecia on the child's temporal scalp was similar to that of Case 1. Cases 1 and 2 presented with port-wine stain patches that were consistent with the characteristic manifestation of PPV type IIb. However, the CMTC of Case 3 met the diagnostic criteria for PPV type Vb. Case 1 was treated with trabeculotomies in both eyes. For Cases 2 and 3, surgical interventions were not considered due to the high risks of antiglaucomatous operation complications. We prescribed them antiglaucoma indications. The simultaneously coexistence of PPV with SWS, Ota nevus, and congenital glaucoma is rare. In the clinic, additional detailed examinations and tests of PPV patients to exclude other ocular abnormalities or extraocular involvements are necessary.
