ABSTRACT
Un melanocitoma del disco óptico es una lesión neoplásica pigmentada y benigna que en promedio mide 2,00mm de diámetro. Melanocitomas del disco óptico más pequeños son raros y no han sido estudiados con múltiples técnicas de imagen. Un caso de un «micromelanocitoma» del disco óptico con un diámetro de 0,71mm fue estudiado con múltiples estudios de imagen, incluyendo autofluorescencia de fondo de ojo, ultrasonido ocular, campos visuales, tomografía de coherencia óptica (OCT) y angiografía por OCT. Mientras que la exploración con biomicroscopia y la autoflourescencia de fondo de ojo revelan cambios compatibles con los casos de tamaño promedio previamente publicados, la OCT, angiografía por OCT y el ultrasonido revelan cambios que difieren de los artículos previos y que podrían ser útiles para el seguimiento (AU)
An optic disk melanocytoma is a benign pigmented neoplasm of the optic disk measuring 2.00mm of diameter in average. Smaller optic disk melanocytomas are rare and have not been studied with multiple imaging studies. A case of a micro optic disk melanocytoma measuring 0.71mm in diameter was studied by multiple imaging modalities, including fundus autofluorescence, ultrasound, visual fields, optical coherence tomography (OCT) and OCT angiography. While clinical appreciation and fundus autofluorescence reveal changes compatible with previously reported cases, OCT, OCT angiography and ultrasound reveal specific changes that could be useful for follow up (AU)
