Purpose:
To describe an infrared gonioscopy system designed to observe the anterior chamber angle under natural mydriasis in a completely darkened room.
Methods:
An infrared light filter was used to modify the light source of the slit-lamp microscope. A television monitor connected to a CCD monochrome camera was used to indirectly observe the angle.
Results:
Use of the infrared system enabled observation of the angle under natural mydriasis in a completely darkened room.
Conclusion:
Infrared gonioscopy is a useful procedure for the observation of the angle under natural mydriasis.
