Home Monitoring Optical Coherence System

Abstract

The invention provides an OCT system suitable for home monitoring of aspects of the retina of an eye by measuring the thickness of the retina at particular location on the retina. A preferred embodiment is capable of making measurements on both eyes and can target a desired location on the retina by means of a fixation display that is viewable by either the eye being measured or the fellow or contra-lateral eye. Various alternate embodiments are taught. In some embodiments an angular scanning device enables a small portion of the retina to be scanned and also enables flexible fixation. In some embodiments correct targeting of the location of the retina to be measured is confirmed by acquiring an image of an outer region of the retina either by means of scanning that region interspersed with acquiring A-scans at the desired location, or by acquiring a full field OCT image of the outer region of the retina while acquiring A-scans at the desired location.
