Clinical significance:
1. Diffuse illumination method: It can roughly inspect the anterior tissues such as the conjunctiva, cornea, sclera, etc.
2. Direct black spot illumination method: The lesions in the illuminated area can be carefully observed.
3. Posterior illumination method: It is mainly used for the inspection of transparent tissue by assisting the light reflected by the posterior tissue to examine the anterior tissue of the eye.
4. Specular reflection illumination method.
5. Limbal spectroscopic illumination.
6. Indirect lighting method, etc.
