Ophthalmic Terminology Simplified
Herewith we present some ophthalmic terminologies and their simple definitions which
may be of extreme use for you in your daily work. This series will be continued in the
alphabetical order in the upcoming issues.
-PPseudo-squint
-RRAPD
The situation in which a person seems to
have a squint but in fact does not. The most
common cause of this is the presence of a
wide nasal bridge (epicanthus).
Relative afferent pupillary defect.
Pterygium
A triangular growth of tissue that grows
form the conjunctiva onto the cornea. If
large it can cause astigmatism.
Ptosis
Recession and resection
The moving of muscles from their original
position to new positions on the eyeball
in order to either weaken (recession) or
strengthen (resection) their pull for the
surgical correction of squints.
Refraction
The hole through which the tears pass into
the canaliculi.
The deviation of light in passing obliquely
from one medium to another of different
density. In ophthalmic practice, refraction
describes the process by which the
prescription of spectacle lenses for an eye is
measured.
Pupil
Refractive error
The round hole in the centre of the iris
that corresponds to the lens aperture in a
camera. The pupil varies in size according
to whether the environment is bright (small
pupil) or dark (large pupil).
When the eye fails to focus light correctly
and needs a lens (for example spectacles or
contact lens) to correct it.
Drooping of the eyelid.
Punctum
Pupillary light reflex
The pupil contracts or gets smaller in
response to a bright light being shone into
it and automatically causes the pupil of the
other eye to contract.
Retinal detachment
The falling away of the retina from its
correct position at the back of the eye,
which leads to a defect in the field of vision
and ultimately loss of vision.
Retinopathy
Disease of the retina, for example, diabetic
retinopathy is disease of the retina
secondary to diabetes.

Answers to True or False on Page 18
1. True - ( Glaucoma often runs in families. If someone in the immediate family has glaucoma,
one should have a comprehensive, dilated eye examination every year or once in two years).
2. True - (The early stages of open-angle glaucoma, have no warning signs. However, as the
disease progresses, a person with glaucoma may notice his or her side vision gradually
failing).
3. True - (Everyone over age 60 is at an increased risk for glaucoma).
4. True - (People with glaucoma usually do not experience pain from the disease).
5. True - (Although glaucoma cannot be cured, one can generally control it with eye drops or
pills or with laser surgery).
6. False - (Increased eye pressure means one is at increased risk for glaucoma, but does not
mean that one has the disease. A person has glaucoma only if the optic nerve is damaged. If
there is no damage to the optic nerve, one does not have glaucoma. Follow the advice of the
doctor).
7. False - (Vision loss from glaucoma is permanent. However, with early detection and
treatment, the progression of visual loss can be slowed or halted and the risk of blindness
reduced).
8. False - (A measurement of eye pressure by tonometry, is not enough to detect glaucoma.
Glaucoma is detected most often during an eye examination through dilated pupils.. When
indicated, a visual field test should also be performed).
9. True - (An eye examination through dilated pupils is the best way to diagnose glaucoma.
Individuals at increased risk for the disease should have their eyes examined through dilated
pupils every one to two years).
10. True - (The anterior chamber depth and volume are smaller in hyperopic eyes. Shallow
anterior chamber is the main ocular risk factor for closure of the angle).
