Case Conference 1 Flashcards
Explain the field of preventive optometry
Optometrist are no longer satisfied in prescribing lenses as prosthetic devices, but consider them as means of maintaining visual efficiency
Explain the field of visual enhancement in optometry
Optometrists possess the key to increased visual efficiency for patients to perform job easily, quickly and efficiently
Based upon the principle of relativity
Physical science
Based upon the concept that the whole organism is more than the sum total of its isolated parts
Biological sciences
Based upon the concept of Gestalt
Psychology
Based upon the concept that vision is a function that involves the whole organism
Field of optometry
Convergence
Skeletal
Accommodation
Visceral
Perceptual
Cortical
Seeks and holds a visual image
Skeletal
Discriminates and defines the image
Visceral
Skeletal: Extrinsic eye muscles, Visceral: _______
Intrinsic eye muscles
A procedure for summing up optometric analytical data for purposes of classification
Case analysis
A normal eye viewpoint which requires that the system must possess certain ideal values in order to be considered normal
Normative viewpoint
A normal eye viewpoint which is free of pathology and has no abnormal disturbance
Pathological viewpoint
A normal eye viewpoint where a normal system is one which agrees with the statistics established for a group of similar system
Statistical viewpoint
3 stages of physical stages that occur under stress
Neural
Neuro-muscular
Muscular
3 stages of physical stages that occur under stress
Neural
Neuro-muscular
Muscular
High reversible, leaving no symptoms
Neural
Still reversible, showing symptoms
Neuro-muscular
An individual who possesses standard acuity without the use of concave lenses and refuse plus lenses
Emmetropia
The transition point between hyperopia and myopia
Emmetropia
An equilibrium state in which the eyes under dissociation have the same posture as the eyes have when they are not dissociated
Orthophoria
Why is orthophoria not ideal?
Because the efficiency of those who are orthophoric is lower than those who are exophoric
If a patient is hyperopic, the eye tended to become?
Less hyperopic
If a patient is emmetropic, the eye tended to become?
Myopic
If a patient is myopic, the eye tended to become?
More myopic
Changes in supporting structures, reversible if accessible, leaving definite symptoms
Muscular
Component of visual pattern
Accommodative and convergence pattern
Component of visual pattern
Accommodative and convergence pattern
Sub-patterns of accommodation
Tonic, aberrational, convergence, and psychic accommodation
The lenticular poise under the conditions of far point fixation with maximum inhibition of activity
Tonic accommodation
Range of performance in the accommodative pattern due to the modification of flux conoid because of spherical and chromatic aberration
Aberrational accommodation
The effect of convergence upon the accommodative pattern
Convergence accommodation
The amount of lenticular accommodation in action due to emotional and psychological reaction of the subject
Psychic accommodation
It provides the mechanism with maintaining single vision
Convergence pattern
The position of the visual axes under conditions of dissociation with far point fixation
Tonic convergence
The amount of convergence in action due to the innervation of accommodation
Accommodative convergence
Buffer area in accommodative pattern
Hyperopia
Buffer area of convergence
Exophoria
Active state inhibition in the convergence pattern
Esophoria
An individual who has acquired myopia at 8
Adventitious myopia
Cyclic steps leading to adventitious myopia
Has made an extreme adaptation in binocularity
Adventitious strabismus
