A 25-year-old otherwise healthy male, after closed globe injury (right eye) he sustained 7 years back, was incidentally found to have a zonular with posterior subcapsular cataract [Figure 1]a and [Figure 1]b (best corrected visual acuity 20/40) on his routine examination. Notable was the “asphericity” of the opacified zonule [Figure 1]b and an opacity communicating from the posterior capsule to the opacified zonule [[Figure 1]c, arrow]. The “communication” might represent the tract of “traumatic hydrodelineation” from the micro-defect in the posterior capsule, which later got fibrosed. The asphericity of the zonule is an indirect indicator of the asphericity of our crystalline lens.[1]
Figure 1: (a) Retroillumination showing cataract; (b) anterior segment optical coherence tomography confirming the cataract to be zonular with the posterior subcapsular component; note the peripheral flattening of the anterior surface of the zonule, making it aspheric; (c) arrow shows a communicating opacity from the posterior capsule to the zonule
