Illumination When Assessing With the Slit Lamp

The illumination when assessing with the slit lamp is crucial, to clearly understand the exact area we are assessing.

The illumination when assessing with the slit lamp is crucial, as for example when assessing the fluid reservoir thickness that we need to note and compare with that observed during the next follow-up visits, verifying further lens settlement. The ocular surface area we are assessing, if not well illuminated, may not be clear (Figure 1).

By slightly illuminating the eye, it is possible to see and document exactly the area we are evaluating (Figure 2).

How to do this?
Some slit lamps have a lamp attached, so you just have to turn it on and position it near the eye you are observing (Video 1).

If the slit lamp does not have this built-in light, it is possible to buy a seperate lamp and position it on your slit lamp. It will light up the eyes and make the evaluation easier (Figure 3).

 

Examples of lamps to add to your slit lamp:
