Annual Ophthalmological Examination

Annual eye examinations should be done on every DM1 and DM2 patient to assess above-described eye problems.

Slit-lamp Biomicroscopic Examination

Slit-lamp biomicroscopic examination must be performed to diagnose these early lens opacities. A general assessment for lens opacities and cataracts may be done during a regular eye exam, but ophthalmologists and optometrists often do not recognize the iridescent lens opacities unless prompted. 

Electroretinogram (ERG)

A moderate-to-advanced cataract can interfere with the diagnosis of retinopathy. ERG is not routinely performed unless retinopathy is suspected by routine eye examinations.
