Secondary intrachoroidal cavitation in a case of iridofundal coloboma.

ABSTRACT

Intrachoroidal cavitation is a morphological entity usually described in high myopic eyes. It is usually seen in peripapillary location, though macular location has also been reported. It has been associated with optic disc tilting and posterior staphyloma. We report a case of a 27 year old female who presented to us with recent onset scotoma in her visual field. On examination she had a fundal coloboma with intercalary membrane detachment with intrachoroidal cavitation at the edge of the coloboma. We hypothetise that this intrachoroidal cavitation is a secondary phenomenon and is responsible for recent onset scotoma in her visual field.
