RESUMO
La cavitación intracoroidea es un hallazgo identificado con OCT descrito inicialmente en pacientes miopes, pero también aparece en pacientes no miopes. Puede presentarse tanto en el área peripapilar como en el polo posterior. El coloboma macular es un defecto del desarrollo embrionario del polo posterior, y en la OCT estructural es imprescindible la ausencia del epitelio pigmentario de la retina y de los vasos coroideos para su diagnóstico. Este caso presenta la cavitación intracoroidea circunscribiendo el coloboma macular, en ausencia de membrana intercalar. La imagen en face permite valorar la relación entre ambas estructuras, así como la magnitud de las mismas. (AU)
Intrachoroidal cavitation is a finding identified with OCT initially described in myopic patients, it also appears in non-myopic patients. It can occur in both the peripapillary area and the posterior pole. Macular coloboma is a defect of embryonic development of the posterior pole, in structural OCT the absence of the retinal pigment epithelium and choroidal vessels is essential. In this case, intrachoroidal cavitation circumscribes the macular coloboma, in the absence of an intercalary membrane. The face image allows us to assess the relationship between the two structures as well as their magnitude. (AU)

Macular coloboma is a defect of embryonic development of the posterior pole, in structural OCT the absence of the retinal pigment epithelium and choroidal vessels is essential. In this case, intrachoroidal cavitation circumscribes the macular coloboma, in the absence of an intercalary membrane. The en face image allows us to assess the relationship between the two structures as well as their magnitude.
