PROFESSIONAL ENGLISH IN USE MEDICINE
UNIT 19
THE EYE

A.       Parts of the eye

 

B.        Examination of the eye
Here is an extract from a textbook description of how to examine the eye.

Look for the squint (strabismus), dropping of the upper lid (ptosis) or oscillation of the eyes (nystagmus). In lid lag, the upper eyelid moves irregularly instead of smoothly when the patient is asked to look down.
They are equal in size
They are regular in outline (evenly circular)
They are abnormally dilated (large) or constricted (small)
They react normally to light and accommodation (focus on near objects)
To test the reaction to accommodation, ask the patient to look into the distance. Hold your finger in front of their nose, and ask the patient to look at it. The eyes should come together, or converge, and the pupils should constrict as the patients looks at the finger.

Check also for cataract (opacity of the lens)
C.       Retinopathy
Hypertensive changes in the retina can be classified from grades 1 to 4.
Grade 1
silver wiring (increase in the light reflex) of the arteries only
Grade 2
grade 1 plus arteriovenous nipping (indentation of veins where they are crossed by arteries)
Grade 3
grade 2 plus flame-shaped haemorrhages and cottonwool exudates.
Grade 4
