Cataracts (lens opacities) are common in all populations and most are related to the physiology of aging. However, many others are the result of gene changes (mutations). Many of these are present at birth and often associated with other health problems.

Dilated eye examinations for lens opacities, retinal hamartomas, or epiretinal membranes may be quite useful even in a child at risk for NF2
Juvenile cataracts may be seen long before a child shows any evidence of vestibular schwannomas

A cortical cataract may give rise to poor vision associated with seeing haloes around lights or seeing things double with one eye.
Posterior subcapsular ~ tend to cause reduction in vision (especially for reading), susceptibility to bright lights and glare.

Closure of the iridotomy site is more likely if a uveitis presented after surgery. Up to 45% of patients will have anterior ~ after laser iridotomy, but these opacifications do not put the patient at an increased risk of cataracts.
