Types of Eye Care Professionals • Ophthalmologist • MD • Prescribes medication • Performs surgery • Optometrist • OD • 4 years of post bachelor’s optometry school
Optician • Technician • Makes and repairs glasses and contact lenses What are the problem areas? What might these eye-medical professionals help detect???
So, What can go wrong? • Loss of acuity • Loss of visual field • Loss on binocularity • Loss of color perception • Loss of ability to process visual information
The Exam • Medical history • Visual acuity • Refraction • External examination • Pupillary testing • Examination of anterior structures • Examination of posterior structures
Visual acuity testing • Charts • 20 foot Snellens • 10 foot HOTV • Preferential looking/grating tests • Optikenetic drum – helps detect the ability to follow moving targets without moving the head • Contrast sensitivity tests
Refraction • Process for determining appropriate prescription for lenses. • Three options: • Subjective refraction (“Which one looks better 1 or 2?”) • Retinoscopy (neutralization of light shined into the eye through lenses
Computerized retinoscopy • Computer shoots a beam of light into the eye and measures its reflection back to the source • A similar device, called an aberrometer, uses “wave-front technology” to measure disturbances (abborations) of the light as it passes through your eye – Developed for Lasik
External Examination • Appearance and symmetry of the face • Skin of the eyelids • Edges of the lids and lashes • Clarity of the cornea, irises, and pupils • Color, texture, and moisture of the conjunctiva • Position, movement, and coordination of the eyes
Pupillary Testing • Light shined directly into the pupils to check for • Reaction in each eye • Consensual responses
Tonometer Checking intraocular Pressure – look at this Old thing! Today, typically Eye- Care Professionals use a tonopen or Applanation Tonometry test
Examination of Posterior Structures • Retinoscope or Ophthalmoscope • Used to examine • Viterous • Retina • Optic disc • Retinoscopy is a way of determining prescription…based on reflection
Slit Lamp • Used primarily to examine the anterior chamber and structures, but may also be used for viterous and retina as well. • Usually involves dilation of the eye and/or use of dye
Your Role • Help your student and family prepare • Explain the tests • Role play • Discuss their questions • Help give them a voice • Attend if you can/if you are permitted/etc.
More Roles • Collaborate with Parents and Doctors • Remember -devices/glasses may be needed at appt. • Provide information and voice concerns • Help the client establish goals • For devices • For target activities
Review after the Appointment Talk to student/client and their family to investigate questions they may have after the appointment Retrieve info from the visit and review and/or do research Explain findings
