Comments:
Cataract is a clouding of the lens of the eye or its capsule sufficient to reduce vision. The formation of cataract occurs more rapidly in patients with a history of ocular trauma, uveitis, or diabetes mellitus. Cataract is an associated diabetic eye problem that could lead to blindness.
Regular eye checkups are important for patients suffering from diabetes mellitus. This helps to early detect abnormalities and to avoid or postpone vision-threatening complications. A comprehensive ophthalmological examination includes:
- check visual acuity with Snellen chart -correct with pinhole if indicated
- examine for cataract
- examine fundi with pupils dilated.
