Ophthalmic contact lens with internal fixation light for examination of the optic nerve head.
Stereoscopic slitlamp examination of the optic nerve head in one-eyed patients is difficult because there is currently no way to provide the patient with a fixation target. This situation is often aggravated in glaucoma patients by a miotic and fixed pupil. We have developed a funduscopic contact lens which incorporates a fixation target, allowing the patient to view the target with the eye being examined. The device has been successfully tested on normal volunteers.
