The list of required practical skills

1. Evaluate the status of the visual sensory system for performance studies of its functions (visual acuity, field of vision, the ability to perceive colors).


Test tasks
1. The patient clearly see objects located at a short distance and poorly perceives distant objects. Please specify the reason for visual impairment:
A. Loss of elasticity of the lens.
B. Weak ciliary muscle.
C. Narrowing of the pupil.
D. Damage to the visual cortex.

2 The patient 60 old clearly see objects located at a long distance and poorly short distant objects. Please specify the reason for visual impairment:


A. Loss of elasticity of the lens, ciliary muscle weakness.
B. Elongation optical axis ca.
C. Lack of vitamin A.
D. retinal detachment.
E. ciliary muscle spasm.

3. The unit is considered to be visual acuity when the angle at which the eye can distinguish between two points is:


A. 1 sec.
B. 10 seconds.
C. 30 sec.
D. 60 sec.
E. 120 sec.

4. Where is the cortical visual analyzer department?


A. occipital cortex .
B. pariental cortex.
C. temporal cortex .
D frontal cortex.
E. hippocampus.

5. In humans, much worse vision in the dark night, visual acuity is normal. Specify the possible cause of this phenomena:


A. Lack of expansion of the pupils.
B. ciliary muscle contracture.
C. Myopia.
D. Deficiency of vitamin A.
E. Lack of cones in the retina.
Standards of answers: 1-D, 2-A, 3-D, 4-A, 5-D.
Materials control for the final stage:
In defense of protocols performed laboratory work students have to answer for following questions:
1. What are the possible ways to correct vision in myopia?
2. How can I correct the vision in hypermetropia?
3. What points should be encouraged in senile hyperopia.
4. Point out possible causes of decline of visual acuity?
5. What is the cause of "blindness"?
6. Why take a drop of atropinefor the eye cramps accommodation?
7. What is the essence of the theory of duality?
8. Where is the central cortical visual analyzer?
9. What is the cause of a violation of color perception?

Answers:
1. Correction of the eye in myopia is the use of scattering lenses in eyeglasses or contact lenses.


2. In hypermetropia should recommend glasses with lenses teams.
3. In senile hyperopia using glasses with lenses teams.
4. The reason for decrease in visual acuity may be a violation of refraction apparatus of the eye, conductor and cortical parts of the visual analyzer.
5. The cause of night blindness is a deficiency of vitamin A, necessary for the synthesis of visual pigment rodopsin.
6. In spasm of accommodation have to take the atropine , as it blocks the M-holinoretseptors ciliary muscle and excludes stimulant effect on his parasympathetic nervous system.
7. The theory of duality states that retinal receptors perform different functions - sticks react to black and white and cones - in colored light.
8. Cortical visual analyzer center located in the occipital lobe cortex (17, 18, 19 filds by Brodman).
9. Violation of the perception of colors associated with congenital anomaly of X-chromosome.
