Part of vision that occurs outside the very center of gaze
Hyperacuity
Peripheral vision
Detection
Crowding phenomenon
Ability to see action or objects that are not in your direct line of vision, but instead taking place on the sides of your vision
Peripheral awareness
Pursuit
Clinical VA
Crowding phenomenon
Amblyopia is characterized by reduced acuity in one eye caused by an abnormal or insufficient stimulation of the binocular system in the early yrs of life
True
False
Ability of the eye/s to focus on stimuli at various distances and in different sequences in a given period of time
Contrast treshold
Accommodative facility
Ocular dominance
Accommodative inertia
Binocular perceptual distortion that is induced when corresponding retinal images of the two eyes are unequal
Metamorphopsia
Cross Dominance
Aniseikonia
Crowding phenomenon
Ability to distinguish 2 lines placed end to end with one of them literally displaced
Hyperacuity
pursuit
Tumbling E
dominant eye
All are definitions of Visual acuity except
Spatial resolving capacity of the visual system
Comparison of hand and ocular dominance
Smallest target measured in an angular substense that an individual is capable ot resolving
determining largest symbol,letters or words that can be identified correctly
which is true about metamorphopsia?
difference in size/shape of the ocular images
Distortion of objects
Which of the statements are true about accommodation?
The far point of distinct vision of an emmetropic eye is at infinity
In order to focus an object at distance of 25cm, an emmetropic eye with +2.00D needs 6D of accom.
It decreases with age
In order to focus an object at a distance of 25cm, an eye with -3.00D needs 2D of accom.
For a comfortable vision, 1/3 of the accom. should be kept in reserve
Which is true about Tonic Accommodation?
also known as dark accommodation
due to the tonus of the ciliary muscle and is active in the absence of stimulus
Both a&b
none
shadow test is an unreliable test for assessing anterior chamber depth
True
false
Constriction of pupil in the opposite eye
Aniseikonia
Indireft reflex
Foveal vision
Direct reflex
Least separation between 2 adjacent points or adj lines that allows the 2 to be seen as separate
Minimum detectable resolution
Separable resolution
None
Both a&b
In Preferential looking, this is based on the knowledge of the infants prefer to look at a patterned rather than a plain surface
True
False
A rare condition in which the px has difficulty altering his or her accommodative response
Accommodative facility
Accommodative infacility
Accommodative inertia
Accommodative fatigue
Absence of accommodative amplitude
Paralysis of accom.
Accommodative fatigue
Gap resolution
The link between accommodation and convergence is known as accommodative convergence and is expressed clinically as
(a)
The optical difference bet. stimulus and the response is denoted as the
proximal accommodation
accommodative fatigue
Lag of accommodation
Lead of accommodation
It is the adjustment of the eye for long distances by relaxation of the ciliary muscles
Negative accommodation
Positive accommodation
It is the adjustment of the eye for short distances by contraction of the ciliary muscles
Positive accommodation
Negative accommodation
Monocular eye movement into the cardinal positions of gaze
version
Pursuit
Duction
vergence
Fusional convergence makes the final adjustment to gain binocular single vision
False
True
The ff are true about Static pupil evaluation
It is a reflex action in response to focusing on near object then looking at distant object
It refers to the measurement of the pupil size under constant stimulus condition
It refers to the simple observation of the pupil in both normal and dim illum.
a ring with a gap
Vernier acuity test
Landolt c
Grating acuity
Cross dominance is when the hand and eye have opposite dominance
True
False
The extent to which the VA chart may be removed toward or away from the patient is referred to as?
Contrast treshold
Light reflex
Depth of field
Static pupil eval
Accommodation exceeding the amount required by a stimulus
proximal accommodation
Lead of accommodation
Lag of acccommodation
Accommodative facility
Accommodation beyond the plane of regard
Lag of accommodation
Lead of accomodation
accommodative infacility
