Is used to measure the clarity of vision or the ability of the visual system to resolve detail

Main purpose is to assess the presence of third-degree fusion

Differentiates between a phoria and a tropia and determines if a tropia is alternating or unilateral

Determines the direction and the magnitude of a phoria or tropia but does not differentiate a phoria from a tropia

The cornea supplies approximately how much of the refractive power of the eye? 1/4 1/2 2/3 3/4

3/4

The instrument used to measure the curvature of the cornea is known as: Lensometer Keratometer Tonometer Slit Lamp

Keratometer

The measurement of intraocular pressure is known as: Keratometry Potential Acuity Tonometry Visual Field

Tonometry

IOP is caused by the production of: Aqueous Humor Vitreous Humor Tonometry Fluorecein

Aqueous Humor

Increased IOP can cause damage to the visual field and is known as: Goldmann's Glaucoma Applanation Afferent Pupillary Defect

Glaucoma

Two methods to measure the IOP (intraocular pressure) are: Goldmann Applanation tonometry and Tonopen Fluorecein and Anesthetic Potential Acuity and Fundus Visual and Non-visual

Goldmann Applanation tonometry and | Tonopen

When performing applanation tonometry, a reading is taken when: The outer edges of the two semi-circles touch The two semi-circles become a full circle No edges of the two semi-circles touch The inner edges of the two semi-circles touch

The inner edges of the two semi-circles touch

When you instill drops in a patient eyes, it's important to record: How long it took to instill the drops in the patient eyes The patient's initial reaction to the eye drops The drops used, concentration of the drops, how many drops were instilled in each eye, and the time that the drops were instilled The tear break-up time

The drops used, concentration of the drops, how many drops were instilled in each eye, and the time that the drops were instilled

Doing a Pinhole Visual Acuity check on a patient can provide valuable information because it can reveal... If a decrease in vision is correctable with lenses and it will show a patient's best potential visual acuity if a patient has Optic Nerve Damage If a patient has an Afferent Pupillary Defect If a patient has visual field loss due to glaucoma

If a decrease in vision is correctable with lenses and it will show a patient's best potential visual acuity

Fundus Photography takes color photos of the fundus which contains: Cornea, Aqueous and Crystalline Lens Iris, Pupil, Vitreous Schlera, Conjunctiva, Lids Retina, Optic Disc, Retinal Vessels

Retina, Optic Disc, Retinal Vessels

Fundus cameras are used to: Take pictures only of the retina Take photos of the retina, iris photos and photos of other structures and abnormalities in and around the eye Assist in measuring the IOP Help measure the depth of the anterior angle

Take photos of the retina, iris photos and photos of other structures and abnormalities in and around the eye

Before fitting a patient with contact lenses, this should be done to assess if a patient has a lacrimal insufficiency: Visual Acuity Tear break-up time Fundus exam Gonioscopy

Tear break-up time

When the anterior chamber angle is considered to be narrow by the van Herick Technique, this should be done before dilating drops are put in the patient's eyes Humphrey visual field Photos taken of the retina Gonioscopy Scleral depression

Gonioscopy

Every point on the visual field corresponds to a point on the: Cornea Iris Optic Nerve Retina

Retina

The absence of retinal receptors form: Scotomas Cataract Glaucoma Astigmatism

Scotomas

Testing a patient's visual field by moving a target through the patient's visual field (meridian-by-meridian) from non-seeing to seeing is known as Harrington Flocks Kinetic Testing Tangent Screen van Herick Technique
