Slit-lamp Biomicroscopy and Photography
High quality optics, lighting and magnification are essential for seeing subtle signs and changes when examining structures at the front of the eye. These are provided by the biomicroscope, also known as the slit-lamp. Structures that are viewed in detail with the slit-lamp include the transparent cornea and conjunctiva, as well as the coloured iris and white sclera.
"a particularly useful tool for showing the functioning of the meibomian glands and the health of the eyelid margins"
Our slit-lamp is fitted with a digital camera that takes both still and video images, and is ideal for recording the appearance of the front of your eye. It is a particularly useful tool for showing the functioning of the meibomian glands and the health of the eyelid margins, both of which are especially important in dry eye disease.
The gonioscope is a fine, smooth mirror that is placed on the cornea, cushioned by thick lubricating fluid. Used in conjunction with the slit-lamp, this enables us to view the anterior chamber angle, where the aqueous humor drains from the front of the eye. Along with images of the angle captured by our optical coherance tomographer (OCT), the slit-lamp and gonioscope are important tools for identifying patients at risk of developing angle-closure glaucoma.
