Fig. 12. Same eye as shown in Figures 10 and 11. With oblique slit-lamp illumination, glaukomflecken of Vogt appear as pleomorphic gray-white patches just beneath the anterior lens capsule. These are presumed to be areas of necrotic lens tissue caused by very high pressure. With time, they lie deeper and deeper beneath the anterior lens capsule as new lens fibers are laid down, but they will persist permanently as silent records of previous high intraocular pressure.
