Weaving lesions, can determine the location of the lesion, nature, size and depth.


--Fundus and other parts of the inspection

Slit lamp microscope if accompanied by accessories, such as: concave concave front mirror, fundus inspection

Check the contact lens, three mirror and anterior chamber angle, etc., respectively, on the fundus macular and to the edge of the serrated edge, anterior chamber angle and other parts for fine examination.
