Dry Eye & Ocular Surface Evaluation
Slit lamps equipped with photography instrumentation are able to image the front of the eye, This includes the eyelids and lid margins, conjunctiva, cornea and punctum, all of which are associated with dry eye disease and ocular surface abnormalities.
Zeiss SL800
Slit Lamp Biomicroscopy
Equipped with Wratten filters and cobalt blue light, these slit lamps are also excellent for ocular surface assessment with vital stains including sodium fluorescein and lissamine green. Areas of the ocular surface that wet poorly, are abraded or are otherwise abnormal are highlighted by vital dye staining.
Much like the Zeiss slit lamp, the Takagi SM-70N is used to image the anterior eye and is also equipped with a Wratten filter and cobalt blue lighting.

Slit Lamp Biomicroscopy
This instrument uses reflective rings to capture an infrared image of the anterior cornea. The quality of these reflections off of the ocular surface can be used to assess tear film and corneal epithelial integrity.
