While simple to perform and generally fairly accurate, a recent study has shown that the Van Herick technique for estimating anterior chamber angle depth can be unreliable in some circumstances.

This applies to males and myopes (people with short sight). The other risk factors are when this technique is performed on individuals of Asian and black race.

As such, it is recommended that when examining people in this demographic, a more reliable test is gonioscopy, especially when performed in a dark room.

Ophthalmology has really come a long way from the earlier times. If you ask me, it is amazing that we are still continuing to grow in this field. Just like other fields of science, ophthalmology can still grow in the future. This blog of yours completely outlines the possibilities of having a better understanding of this field of science. I hope that I can live to see the day when everything is at the pinnacle of success, especially science and biology.
