Eyenatomy
This is the front, transparent surface of the eye and accounts for approximately 2/3rds of its refractive power.
What is the Cornea?
This refractive state occurs when the eye is too long for the focal power of the cornea and lens.
What is Myopia or "nearsightedness"?
This is the measurement of a patient's ability to see fine detail.
What is Visual Acuity?
This condition is characterized by cloudiness in the crystalline lens.
What is a Cataract? (Or What are Cataracts?)
This short phrase summarizes the reason for the patient's visit. This longer phrase contains details surrounding that reason and requires at least 4 pertinent points of inquiry.
What is the Chief Complaint (CC)? What is the History of Present Illness (HPI)?
This structure controls the amount of light entering through the pupil.
What is the Iris?
A plus "+" power lens is useful for correcting this type of refractive state.
What is Hyperopia or "farsightedness?"
This is the common vision testing chart used to assess distance visual acuity.
What is a Snellen Chart?
This condition refers to inflammation of the clear mucous membrane that covers the outer surface of the orbit and inner surface of the eyelids.
What is Conjunctivitis?
This portion of the patient work-up assesses the range of motion and smoothness of a patient's eye movement.
What is the Extraocular Motility Exam (EOM)?
This structure translates light input into electric signals which pass through the nerves.
What is the Retina?
This refractive condition is characterized by a difference in corneal surface curvature along differnent meridians.
What is Astigmatism?
This test is performed when the distance visual acuity result is worse than 20/30.
What is a Pinhole Acuity Test?
This condition is characterized by reduction or distortion in central vision and deterioration of the retina.
What is Macular Degeneration?
This portion of the patient work-up is a broad assessment of the patient's field of vision.
What is the Confrontation Visual Field Test (CVF)?
This group of 6 structures together control eye movement.
What are the extraocular muscles?
Lack of this capability often necessitates the use of bifocal or progressive style lenses in patients over the age of 40.
What is Accommodation?
This is the notation for a visual acuity score where the patient can only see hand motion.
What is HM?
Flashes and floaters could be indicators of this condition.
What is a Retinal Detachment? (Or what is a Detached Retina)?
Under direct illumination, the pupil being lit does this. At the same time, the pupil not being directly lit does this.
What is constriction? What is also constriction? (Direct and Consensual Constriction)
This region of the eye is where light is most directly focused and is responsible for our detailed central vision. This is the center of that region, often used as a physiological landmark.
What is the Macula? What is the Fovea?
This is the general process of measuring a glasses lens. This process comes in 2 common varieties.
What is Lensometry? What are Manual and Automated (Automatic is acceptable as well)?
A patient's visual acuity comes out to 20/50. The "20" value corresponds to this distance. The "50" value corresponds to this other distance.
What is the distance between from at which the patient is reading a specific line on the chart? What is the distance at which a person with normal vision could read the same line on the chart?
This disease is characterized by degradation of the optic nerve and gradual loss vision, typically starting at the periphery. Nearly 80% of this condition is further characterized as this form.
What is Glaucoma? What is Open-Angle Glaucoma?
Pseudoisochromatic/Ishihara and the 15-hue/Farnsworth-Munsell D-15 test are both this kind of testing.
What is Color Vision testing?
