An apparatus for detecting ophthalmic diseases such as an inflammation in a patient's eye (11) includes means of focusing a laser beam (L) at a selected spot (P) in the eye. The light scattered from the eye is photoelectrically detected through a mask (26) with a slit (26a) and converted into an electrical signal which is subsequently used to determine the protein concentration essential to ophthalmic disease detection in the patient's eye. A light shield member (61) for blocking diffused light from the eye or scattered light from the laser beam is provided in the slit (26a) to improve the S/N ratio of the electrical signal to be processed. |
