What is the principle of anterior chamber depth measurement?
The measuring principle of anterior chamber depth is based on the “optical section” through the anterior chamber by means of a slit lamp with subsequent image analysis. The right eye is illuminated from the right; the left eye is illuminated from the left at an angle of approximately 30 degrees relative to the optical axis. The measurement is performed by image analysis. The instrument measures the anterior-chamber depth (ACD) as it is usually measured in biometry. Anatomically, this is the anterior chamber depth plus corneal thickness.
