Anterior polar cataract
This cataract is small but easy to see. Right in the middle of the pupil is a white dot. This is an anterior polar cataract, a not-uncommon finding. These small opacities are easy to see under the microscope, and even with a careful penlight exam, but generally don’t disturb vision much compared to other cataract types.
congenital cataract
This opacity is small, and despite it’s location in the visual axis, does not affect vision much given it’s anterior distance from the eye’s “nodal point.” This same opacity on the BACK surface of the lens would have much more deleterious affect on acuity.
Slit-lamp of congenital polar cataract
The beam of light allows you to appreciate the slightly raised surface that this opacity forms on the front portion of the lens.
