Procedures for Health Care Personnel

Instructions

After completion of MDH or equivalent training, the following two procedures can be performed by health care personnel, including:

• Nurses, including public health and school nurses.
• Ophthalmic or optometric staff.
• Other trained medical personnel.

These procedures should be performed routinely by nurses approved to perform C&TC screenings. These procedures are not included in general mass screenings, but can be performed as an additional screening for children who do not pass any component of the vision screening procedures.

Provider Roles in C&TC Clinics

Primary Care Provider

Usually updates history and performs the ophthalmoscope evaluation and tests muscle balance (Binocular Fix and Follow, Unilateral Cover Test, and corneal light reflex) as part of the physical exam.

Medical Assistant or Nurse

Usually performs visual acuity screening, for near and distance.

Note: A child who wears glasses and is under the care of an eye care professional needs an age-appropriate visual acuity screening performed with their glasses on. They do not need screening for near vision using the Plus Lens procedure performed.
