A method to determine an ophthalmic tissue structure comprises measuring image data for a range of depths corresponding to a target point in an eye with an axial scanner with a probe; determining an image information by an imaging processor from the image data; identifying a tissue pathology corresponding to the target point by the processor from the image information; and signaling a user by a user indicator based on the identified tissue pathology. A corresponding apparatus comprises an axial scanner with a probe to measure image data for a range of depths corresponding to a target point in an eye; a processor to determine an image information from the image data, and to identify a tissue pathology corresponding to the target point from the image information; and a user indicator to signal a user based on the identified tissue pathology.
