"Macular sink hole" with intrachoroidal cavitation in a case of pathological myopia.

Intrachoroidal cavitation (ICC) is a morphological feature outlined by optical coherence tomography and is characterized by presence of a hyporeflective space beneath the unaltered retinal pigment epithelium. It can be peripapillary or macular in location. Macular ICCs are reported in both myopic and non-myopic eyes. We report a case of full thickness macular hole with retinal incarceration into the macular ICC in a patient with pathological myopia. The term "Peripapillary sink hole" has been described in the literature. We propose the use of term "Macular sink hole" for our case owing to similar findings in the macula.
