Ophthy medical terms Flashcards
photophobia
light sensitivity
diplopia
double vision
pseudophakia / pseudophakic
artificial lens is in place - status of a person after cataract surgery
Aphakic
There is no IOL (intraocular lens)
Snellen Eye Chart
Eye chart containing various letter sizes
Slit lamp examination
patient places chin in chinrest and ophthalmologist uses light and microscope to examine eye
Occluder
Use to assess visual acuity, allows full coverage of eye that is not being tested (blocks one eye)
Pinhole testing
Occluders contain a flap with pinholes, looking through them is equivalent to squinting. Tests best visual acuity of the eye - may indicate refractive error or peripheral cataract
Dilated Fundus Exam
Instilling dilating drops and using the slit lamp to examine the fundus (back of eye_
Intraocular pressure
Normal between 8-21
Astigmatism
Slightly abnormal curvature of the cornea
Light perception (LP)
Used to express visual acuity where patient is only able to sense light
No light perception (NLP)
Visual acuity where patient is not able to sense light
Hand motion (HM)
Patient can only sense hand motion
Bifocal (BF)
Refractive lenses that correct for distance and near vision. Distinct lines separating the distance portion from the near
Trifocal (TF)
Refractive lenses that correct for distance, intermediate, and near vision. 2 distinct lines in lenses separating each portion
Progressive addition lens (PALs)
Progressive lenses, or PALs - bifocals but without the distinct line
Confrontational Visual Fields (CVF)
to assess peripheral vision, patient focuses on physician with one eye covered and tries to see the number of raised fingers without looking at hand of the individual
Extraocular Motility (EOMs)
don’t move head, follow the fingers of physician with eyes - a strabismus test. Important if patient complains of diplopia
Goldmann Applanation Tonometry
Measuring of IOP
Tonopen
measures IOP
iCare
measures IOP, best for kids
IOL master
measures needed replace
phoropter
used to figure out corrective error. Subject measurement - patient input is required
autorefractor
determines refractive error for corrective lenses by automation
Lensometer
obtains readings and measurements of patient’s current corrective lens
Pachymeter
measures corneal thickness
Manual K
obtains readings of corneal curvature
Brightness Acuity Test (BAT)
evaluates cataract severity and density
Corneal Sensitivity Test
tests difference in sensitivity between affected and unaffected eye
Corneal Topography
obtains readings of curvature of cornea
Humphrey Visual Field (HVF)
automated test to assess visual field
Goldman Visual Field
longer than HVF, manual.
