Which of the following diseases is concerned with eye?
-
Sarcoma
-
Glaucoma
-
Lymphoma
-
Myeloma
Sarcoma is the cancer of connective tissues, lymphoma is cancer of lymphatic tissue, myeloma is the cancer of plasma cells. Whereas, glaucoma is a condition that causes damage to the eye's optic nerve and gets worse over time due to viterous humor not being drained and causing pressure on the eye ball.
Thus, the correct answer is option B.

Condition in which one can see nearby objects clearly but can not see distant objects distinctly is called as:
-
Myopia
-
Night blindness
-
Color blindness
-
Farsightedness
Myopia is a condition in which the light rays entering the eye converge in front of the retina instead of on the retina, for objects that are at a greater distance.
Using LASIK we can treat:
-
astigmatism
-
hypermetropia
-
myopia
-
All of the above
LASIK is a laser eye surgery which helps treat astigmatism, hypermetropia and myopia. It cannot treat colour blindness as it is not caused by lens defect of eye.
Which of the following disease is related with eye?
-
Sarcoma
-
Glaucoma
-
Lymphoma
-
Myelenoma

-
Colour blindness
-
Total blindness
-
Night blindness
-
Myopia
Nyctalopia also called night blindness, is a condition making it difficult or impossible to see in relatively low light. It is a symptom of several eye diseases. Night blindness may exist from birth, or be caused by injury or malnutrition (for example, a lack of vitamin A). It can be described as insufficient adaptation to darkness.
Rhodopsin helps seeing lighted things and is synthesized in the presence of vitamin A (retinol). Its deficiency leads to lack of clear vision during night.
Person who cannot see distant objects is suffering from
-
Cataract
-
Hypermetropia
-
Long sightedness
-
Myopia
The lens capsule is attached to the ciliary body by a ligament and serves to refract and focus light rays on the retina. Loss of flexibility with age causes presbyopia, characterized by focusing of the image behind the retina. Likewise, too short eyeball causes hyperopia (long-sightedness). In both cases, distant images are clear but the nearby images are blurry and the condition is termed as hypermetropia.
Too short an eyeball or too flat a lens produces
-
Nearsightedness
-
Astigmatism
-
Myopia
-
Hypermetropia
The lens capsule is attached to the ciliary body by a ligament and serves to refract and focus light rays on the retina. Loss of flexibility with age causes presbyopia, characterized by focusing of the image behind the retina. Likewise, too short eyeball causes hyperopia. In both cases, distant images are clear but the nearby images are blurry and the condition is termed as hypermetropia.
Reduction is the elasticity of eye lens with age may result in
-
Cataract
-
Myopia
-
Presbyopia
-
Hypermetropia
The lens capsule is attached to the ciliary body by a ligament and serves to refract and focus light rays on retina. Loss of flexibility with age causes presbyopia, characterized by focusing of image behind the retina. Likewise, too short eyeball causes hyperobia. In both cases, distant images are clear but the nearby images are blurry and the condition is termed as hypermetropia. This makes option C correct and option D incorrect. On the other hand, myopia or nearsightedness is caused by elongation of eyeball which results in focusing of image in front of retina. Thus, the distant images are blurry but the nearby images are clear. This makes option B incorrect. Cataract is characterized by presence of opaque lens, incapable of transmitting the light rays and is corrected by surgical replacement of lens with artificial lens. This makes option A incorrect. Correct answer is C.
Short sightedness is otherwise known as
-
Myopia
-
Hyperopia
-
Astigmatism
-
Presbyopia
The lens capsule is attached to the ciliary body by a ligament and serves to refract and focus light rays on the retina. Loss of flexibility with age causes presbyopia, characterized by focusing of the image behind the retina. Likewise, too short eyeball causes hyperopia (long-sightedness). In both cases, distant images are clear but the nearby images are blurry and the condition is termed as hypermetropia.
Concave lens is used to correct
-
Myopia
-
Presbiopia
-
Hypermetropia
-
Cataract
Myopia is nearsightedness and short-sightedness, is a condition of the eye where the light that comes in does not directly focus on the retina but in front of it, causing the image that one sees when looking at a distant object to be out of focus, but in focus when looking at a close object.
It can be corrected by the use of corrective lenses that have a negative optical power i.e., concave glasses which compensates for the excessive positive diopters of the myopic eye.
So, the correct answer is option A.
Presbyopia is connected by
-
Concave lens
-
Convex lens
-
Bifocal lens
-
None of the above
Which of the following is caused due to the formation of an opaque membrane once the eye lens?
-
Presbyopia
-
Astigmatism
-
Cataract
-
Myopia
Cataract is a problem of an eye. It arises in old age it is caused due to the formation od an opaque membrane over the eyeless. This member reduces the intensity of light falling or the eye lens. Cataract is corrected by surgical replacement of lens with the artificial lens.
Conjunctivitis is
-
The number of conjunctions in the english grammar
-
The conjunction between ball and socket arrangement of human bones
-
A common infection that affects our eyes
-
A virus which attacks conjunctiva in the eyes
Conjunctivitis is an infection of the eyes. In this the conjunctiva which is the thin skin present on the front of the eye becomes swollen. It may affect one or both eyes. The eyes become red and sticky or watery that causes eye surface irritation. So, the correct answer is option C.
Which of the following occurs in persons suffering from myopia?
-
The eye ball is shortened
-
Ciliary muscles contract
-
The eye ball elongates
-
The retina expands
The shape of the lens of the eye is regulated by the suspensory ligaments and ciliary body. The focal length is adjusted by their regular contraction and relaxation. Myopia is a condition of the eye where light focuses in front, instead of on the retina. This causes distant objects to be blurry while close objects appear normal. Myopia is corrected by using a concave lens. This defect arises either by elongation of the eyeball of the excessive curvature of the cornea. In this far point of the suffering myopia cornea close to the eye.
In the myopia, eye defect, the light rays from iris
-
Do not enter the eye at all
-
Come to a focus at back of retina
-
Come to a focus in front of the retina
-
Come to a focus in between retina and iris
In the following abnormalities of the eye, which one is a serious condition that leads to blindness?
-
Presbyopia
-
Myopia
-
Hypermetropia
-
Glaucoma
Loss of flexibility in crystalline lens with age causes presbyopia which includes focusing on the image behind the retina. Both hypermetropia and presbyopia cause the formation of blurry nearby images which can be corrected by wearing of the convex lens. Myopia is caused by elongation of the eyeball which results in focusing of the image in front of retina and forms blurry distant images. Myopia is corrected using the concave lens. Glaucoma is caused by blockage of tiny ducts that drain the excess aqueous humor from anterior compartment causing a buildup of aqueous humor. This causes compression of the arteries that serve the nerve fibers of the retina due to increased pressure. The death of nerve fibers due to lack of nutrients makes the person partially blind. Thus, the correct answer is option D.
The defect of eye develops in the old age because
-
Lens becomes opaque
-
Eye ball becomes small
-
Eye ball becomes long
-
Lens looses its elasticity
Presbyopia is the defect of old age in which both the near and distant objects are blurred The elasticity of lens of eye decreases hence the accommodation power diminishes.

Helen Adams Keller was born a healthy child in Tuscumbia, Alabama, on June 27, 1880. At the age of 19 months, Helen became deaf and blind as a result of an unknown illness, perhaps rubella or scarlet fever. As Helen grew from infancy into childhood, she became wild and unruly.As she so often remarked as an adult, her life changed on March 3, 1887. On that day, Anne Mansfield Sullivan came to Tuscumbia to be her teacher. Anne began her task of teaching Helen by manually signing into the child's hand. Anne had brought a doll that the children at Perkins had made for her to take to Helen. By spelling "d-o-l-l" into the child's hand, she hoped to teach her to connect objects with letters. Anne took Helen to the water pump outside and put Helen's hand under the spout. As the cool water gushed over one hand, she spelled into the other hand the word "w-a-t-e-r" first slowly, then rapidly. Suddenly, the signals had meaning in Helen's mind. She knew that "water" meant the wonderful cool substance flowing over her hand. Quickly, she stopped and touched the earth and demanded its letter name and by nightfall, she had learned 30 words.

False
- Helen Keller was born on June 20, 1880. She was an author, lecturer, and crusader for the handicapped. She was born physically normal in Tuscumbia, Alabama. She lost her sight and hearing at the age of nineteen months ( 1 year 7 months) due to an illness and had a high fever called scarlet fever. Her parents were Kate Adams Keller and Colonel Arthur Keller. Her teacher was Anne Sullivan who taught her.
Trachoma is a disease of the __________.
-
Ear
-
Larynx
-
Brain
-
Eye
Trachoma is an infectious disease caused by bacterium Chlamydia trachomatis. The infection causes a roughening of the inner surface of the eyelids. ... Untreated, repeated trachoma infections can result in a form of permanent blindness when the eyelids turn inward. So, the correct option is :D" (Eye).
Which of the following eye defect occure due to short eye ball or lens becoming flattened resulting in the formation of image beyond retina?
-
Astigmatism
-
Myopia
-
Hypermetropia
-
Presbyopia
When the light rays converge at a point in front of the retina and then divert to form a blurred image on it, the defect is known as
-
Myopia
-
Hypermetropia
-
Astigmatism
-
Presbiopia
Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye. This causes light rays to focus at a point in front of the retina, rather than directly on its surface. Nearsightedness also can be caused by the cornea or lens being too curved for the length of the eyeball.
In old age, lens loses its ability to focus because of loss of elasticity and ability to accomodate called as
-
Astigmatism
-
Trachoma
-
Glaucoma
-
Presbyopia
Presbyopia is a condition associated with aging in which the eye exhibits a progressively diminished ability to focus on near objects. Loss of elasticity of the crystalline lens, changes in the lens curvature from continual growth and loss of power of the ciliary muscles may be the cause of presbyopia .
The lens becomes opaque in
-
Myopia
-
Hypermetropia
-
Astigmatism
-
Cataract
A cataract is a common eye condition, where the lens becomes progressively opaque, resulting in blurred vision, incapable of transmitting the light rays and is corrected by surgical replacement of lens with the artificial lens. Thus, the correct answer is option D.
Recently there was a report on adverse effect of wearing neck tie. Tight neck tie may cause
-
Glaucoma
-
Hypertension
-
Hoarseness of voice
-
Hyperthyroidism
Tight neck ties constrict the jugular vein. This constriction may raise blood pressure within the eye and cause an increase in intraocular pressure (IOP). The increased IOP may put tight neck tie wearers at risk for developing glaucoma.
A person is wearing spectacles with concave lenses for correcting vision. While not using the glasses, the image of a distant object in his case will be formed
-
On the blind spot
-
Behind the retina
-
In front of the retina
-
On the yellow spot
Myopia occurs when the light is focused in front of the retina. It occurs because either the eyeball is too long, or because the cornea is too curved. People with short sight are not able to see distant objects clearly. Concave prescription lenses (called as minus lenses) are used to bend light rays slightly outwards. The light rays then have a greater angle to bend back to focus when traveling through the cornea and lens. As a result, the light rays focus further back on the retina.
In the following abnormalities of the eye, which one of the following is a serious condition that leads to blindness?
-
Presbyopia
-
Myopia
-
Hypermetropia
-
Glaucoma
-
Astigmatism
Glaucoma is a group of ocular (eye) disorders resulting in optic nerve damage or loss to the field of vision, caused by a pressure buildup of the fluid of the eye. The increased pressure, called as intraocular pressure, can damage the optic nerve, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision. Without treatment, glaucoma can cause total permanent blindness within a few years.
Cataract is a common symptom with the patients who consume .......... for long.
-
Analgesic drugs
-
Alcohol based drugs
-
Steroids
-
All of the above
A cataract is a clouding of the lens in the eye, that affects vision. Most cataracts are related to aging. People with diabetes or those taking high doses of steroid medications have a greater risk of developing subcapsular cataract (the one that occurs at the back of the lens).
Thus, the correct answer is the option (C), 'Steroids'.
The defective condition of accommodation of the eye in which distant objects are clearly seen but near objects are indistinct is
-
Astigmatism
-
Presbyopia
-
Myopia
-
Hypermetropia
Hyperopia or hypermetropia, is a refractive error. Ideally, the cornea and lens, the two focusing structures in the eye, focus images directly on the surface of the retina. If the eye is too short, or the focusing power is too weak, the image is focused behind the retina. At the retinal surface, the image is blurred. Thus, the vision, too, is blurred.
Convex lens is used to correct
-
Hypermetropia
-
Myopia
-
Cataract
-
Glaucoma
Hypermetropia occurs when the light is focused behind the retina. So, the lens changes its thickness, which aims to bring the light into focus on the retina - a process is called as accommodation. But, people with long sight cannot accommodate fully and so the light does not focus sharply and vision is blurred. This occurs because either the eyeball is too short, the cornea is too flat or the lens cannot become round enough. The simplest, cheapest and safest way to correct long-sightedness is with glasses.
Night blindness is caused due to
-
Hypermetropia
-
Myopia
-
Defective cornea
-
Deficiency of rhodopsin in rods
Rhodopsin serves as a visual purple pigment of rod cells and is responsible for night vision. Rhodopsin deficiency causes night blindness. Myopia is caused by elongation of eyeball while shortening of eyeball causes hypermetropia. The cornea is the transparent anterior window of an outer layer of the eyeball and does not have rods. Thus, the correct answer is option D.
To correct myopia, one should use
-
Convex lens
-
Concave lens
-
Plane lens
-
None of the above
Myopia also known as nearsightedness or short-sightedness is a condition of the eye where light focuses in front, instead of on the retina. People having myopia can see close objects clearly, but objects farther away appear blurred. It occurs if the eyeball is too long or the cornea is too curved. So, the correct answer is option B.
Which one of the following diseases in man belongs to the same category as haemophilia?
-
Hypermetropia
-
Rabies
-
Night blindness
-
Colour blindness
Colour blindness and haemophilia are both X-linked recessive disorders.
Which statement is incorrect about cryosurgery
-
Liquid nitrogen is,used
-
Used in treatment of warts
-
Used in eye surgery
-
Destroy the cancerous tumours
cryosurgery is a treatment that involves extreme cold temperatures by the use of liquid nitrogen to freeze the diseases cells like the tumors, warts on the skin and abnormal cells. Hence the correct answer is option C.
In old age farsightedness is a defect of eye in man, in which
-
Eye ball becomes short
-
Eye ball becomes elongated
-
Lens becomes less elastic
-
Lens become more spherical
Presbyopia is caused by an age related process. It occurs due to a gradual thickening and loss of flexibility of the natural lens inside the eye. These age related changes occur within the proteins in the lens, making the lens harder and less elastic over time. Age related changes also take place in the muscle fibers surrounding the lens. Changes in the lens curvature progressively cause diminished ability to focus on near objects.
What statement is wrong about conjunctiva?
-
Ectodermal origin
-
Presents on the central part of cornea
-
Vascular
-
Covers the anterior part of sclera
The epithelium of cornea, lens, and conjunctiva are of ectodermal origin. It is made up of the surface ectoderm. It is absent in the central part of the cornea. Conjunctiva is supplied with blood vessels. It is highly vasculated in the form of fine capillaries. The sclera is the opaque part of the fibrous coat which covers the posterior part of the eyeball. The conjunctiva covers the sclera. The sclera is visible through the transparent bulbar conjunctiva.
When the canal of schlemm is blocked, what condition is developed?
-
Intraocular pressure is increased
-
Retina start to damage
-
Person may become blind
-
All of the above
The canal of Schlemm is a channel in the eye that collects aqueous humor from the eye and moves it into the bloodstream. If the canal is blocked, the pressure in the eye can increase, resulting in glaucoma. Glaucoma is a condition that causes damage to the eye's optic nerve. It is associated with a buildup of pressure inside the eye. The increased pressure, called as intraocular pressure, can damage the optic nerve, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision. Thus, the correct answer is option D.
Name the condition of the eye which causes round objects to appear as though they were oval?
-
Astigmatism
-
Presbyopia
-
Myopia
-
Retinitis
Cataract is a disease of
-
Ears
-
Nose
-
Eyes
-
Throat
Cataract is due to clouding of the lens. Due to this, the lenses become opaque and the vision is impaired. In this condition, an operation is needed. Cataract is very common in old age.
Which of the following medicines is used to dilate pupil?
-
Atropine
-
Cocaine
-
Beladonna
-
All of the above
Medicines which are used to enlarge or dilate the pupil for the eye examination is called as dilating drops such as atropine, cocaine and scopolamine. These chemicals are derived from belladonna. Atropine works by blocking muscarinic receptors, that are found in the muscles of the eye. These receptors are involved in controlling the size of the pupil and the shape of the lens. Thus, the correct answer is option D.
Which of the following is a/are Braille code/s?
-
Unified English Braille (UEB) Code
-
European Braille Code (EBU)
-
Cyprus Braille Code
-
All of the above
- The Nemeth Braille Code for Mathematics is a Braille code for encoding mathematical and scientific notation linearly using standard six-dot Braille cells for tactile reading by the visually impaired.
- The code was developed by Abraham Nemeth. The Nemeth Code was first written up in 1952. Different languages have different types of braille code like example :
- Unified English Braille (UEB) Code
- European Braille Code (EBU)
- Cyprus Braille Code. Hence, Unified English Braille (UEB) Code, European Braille Code (EBU), Cyprus Braille Code are Braille codes.
Louis Braille was born in
-
Coupvray
-
Bordeaux
-
Toulouse
-
None of the above
- Louis Braille was born in Coupvray, a small town about twenty miles east of Paris, on 4 January 1809.
- He and his three elder siblings – Monique Catherine (b. 1793), Louis-Simon (b. 1795), and Marie Céline (b. 1797)– lived with their parents, Simon-René and Monique, on three hectares of land and vineyards in the countryside. Hence, Louis Braille was born in Coupvray.
What is sign language?
-
Making gestures with out speaking
-
Language written on paper
-
Language which we speak
-
All of above
Sign language is represent by making gestures without speaking. This language cannot be written or spoken. Normally this language is used for people who cannot speak or listen.
How many combinations can be made by using 6 dots in Braille script?
-
64
-
63
-
61
-
62
- A cell is made up of six dots that fit under the fingertips, arranged in two columns of three dots each.
- Each cell represents a letter, a word, a combination of letters, a numeral or a punctuation mark.
- The first ten letters of the alphabet are formed using the top four dots (1, 2, 4, 5). This results in 2*2*2*2*2*2=2^6=64 different patterns of raised/unraised dots.
- But, according to the Braille description, we must eliminate one of these 64 possible patterns, because at least one dot must be raised. Therefore, there are 63 possible raised-dot patterns.
Which of the following does not have separate symbols in Braille Script?
-
Capital letters
-
Small letters
-
Numbers

- Braille is a system of reading and writing by touch used by the blind. The basic Braille symbol, called the Braille cell, consists of six dots arranged in the formation of a rectangle, three dots high and two across.
- Other symbols consist of only some of these six dots. It consists of arrangements of dots which make up letters of the alphabet, numbers, and punctuation marks.
- The basic Braille symbol, called the Braille cell, consists of six dots arranged in the formation of a rectangle, three dots high and two across. There are no different symbols for capital letters in Braille. Hence, Capital letter does not have separate symbols in Braille Script
Virtually impaired people are less sensitive to touch and their hearing power is also very weak.

- Blind people can't physically hear better than others.
- Yet blind people often outperform sighted people in hearing tasks such as locating the source of sounds.
- So blind people may have lost their vision, but this leaves a larger brain capacity for processing the information from other senses. Hence, Virtually impaired people are less sensitive to touch and their hearing power is also very weak.

- Uncontracted braille translates each print character into a braille character or cell. It is great for basic labelling of objects like CDs or canned food in the cupboard.
- Uncontracted braille was previously known as Grade 1 braille. Basically, uncontracted braille includes the letters “A” through “Z”.
- Whereas Contracted Braille consists of a 'shorthand' in Braille some words have shortcuts such as the letter 'C' represents the word 'can' or 'td' is the word today. Hence, When every letter of every word is expressed in Braille, it is called as Uncontracted Braille.
