Q

Optometric horizon of today are expanded into 2 directions:

A

Preventive optometry
Field of visual enhancement

23
Q

Explain preventive optometry

A

Optometrists are no longer satisfied in prescribing lenses as a prosthetic device, but consider them a means of maintaining the visual efficiency of the patient in spite of the impact of school or industry.

24
Q

Explain field of visual enhancement

A

Increase visual efficiency for these patients so that they can perform their jobs easily, quickly, and accurately.

25
Old idea of optometry:
Correction of EOR Refractionist Refractive approach-inadequate
26
New idea of Optometry:
To provide an environment in which the individual can re-adapt himself to his life necessities Optometrist Vision is a function that involves the whole organism. Eyes cannot be studied in isolation. More emphasis on binocular vision and more attention given to near-point seeing problems.
27
Includes the visual acuity of the individual in his environment
Vision
28
Does not force the patient to give up all accommodative effort, but to maintain it a minimum level which is conductive to that individual
Fogging technique
29
Purpose of case analysis
(A) Find the limitations of the prescriptible lens for distance and for near (B) To determine whether the case can be handled by: lens application alone, by vision training and lenses, or by vision training alone; (C) To follow the changes in relationship between accommodation and convergence brought about by the new Rx or the vision training program or both (progress report examination)
30
Explain normative physical viewpoint of a “normal eye”
31
Explain the pathological viewpoint of a “normal eye”
32
Explain statistical viewpoint of a “normal eye”
33
In bernell peripheral awareness chart, letters are larger when viewed ____
Eccentrically
34
Worth 4 dot: Two red dots
OS SUPRESSION
35
Worth 4 dot: Three green dots
OD SUPRESSION
36
Worth 4 dot: Red dots on the right of the greens
ESO deviation
37
Worth 4 dot: Red dots on the left of the green dots
EXO deviation
38
Length of a brock string
10 ft.
39
Gross stereoscopic vision is at ____ seconds of arc
3,600
40
Screening test designed for early detection of problems with stereoscopic vision in children and adults without the need for dissociating glasses
Lang-stereotest
41
King Devick Test: Average score >14 yrs. Old
Less than 60 sec. For 3 cards
42
To test the ability to follow a slowly moving target
Smooth pursuits
43
To test the ability of the eyes to move quickly between targets
Saccades
44
Measure the ability to view a near target without diplopia
NPC
45
Ability to inhibit vestibular-induced eye movements using vision
Visual motion sensitivity
46
Used to ensure the speed rotation is maintained
Metronome
47
Assess the ability to stabilize as the head moves
VOR Test
48
From an optometrict viewpoint, the normal eye is
Hyperopic and exophoric
49
Buffer area for convergence pattern
Exophoria
50
Buffer area for accommodative pattern
Hyperopia
51
As fixation was prolonged, a tendency towards myopia was found If hyperopic—
eye tended to become less hyperopic
52
As fixation was prolonged, a tendency towards myopia was found If emmetropic—
eye tended to become myopic
53
As fixation was prolonged, a tendency towards myopia was found If myopic—
eye tended to become more myopic
