A 23-year-old male came to our hospital complaining of defective vision and glare in his right eye (OD) for 6 months. He had a history of blunt trauma to his OD a few years back when he got injured by a fist. His best-corrected visual acuity was 6/9 in OD and 6/6 in the left eye. His intraocular pressure was normal in both eyes. Slit-lamp evaluation revealed a peculiar type of cataract in the OD. There was anterior subcapsular cataract with multiple mushroom-like projections from its surface (Enoki mushroom-like cataract) [Figure 1]. Enoki mushrooms or Enokitake are edible mushrooms with thin stems and small caps on top and are predominantly used in soups. Gonioscopy showed open angles with no angle recession, and fundus examination was normal. He had no systemic illness, and basic systemic work-up comprising a complete blood count, blood sugar, renal function test, and fasting lipid profile was within normal limits. As he was symptomatic, a routine uncomplicated phacoemulsification was performed. Care was taken to avoid disrupting the projections during the initiation of capsulorrhexis.

Blunt trauma can result in coup and contrecoup injury to the lens. There is also sudden anteroposterior compression of the eyeball with equatorial expansion. This stretching can disrupt the lens capsule and the zonules. A coup injury can lead to direct damage to the lens capsule. In a contrecoup injury, there are shock waves traveling within the eye, and these shock waves lead to cortical opacification.[1] The explanation is that trauma-related dysfunctional lens epithelium results in swelling of the superficial cortical lens fibers which later undergoes degeneration. Consequently, there is a lamellar zone of vacuolation and opacity formation. With time, as new clear lens fibers form, these opacities become separated from the subcapsular area and become deeper.[2],[3] It is possible that in our patient, the degenerated lens fibers got pushed up rather than deeper by the new lens fibers, leading to focal elevations resembling the mushrooms. This image is presented because of the distinctive nature of the cataract.
