Total questions: 25
Worksheet time: 13mins
What is the primary function of a slit lamp?
To measure refractive error.
To provide a magnified, stereoscopic view of the eye.
To measure intraocular pressure.
To assess color vision.
Which part of the eye is NOT typically examined with a standard slit lamp examination?
Cornea
Iris
Retina
Eyelid
The slit lamp's illumination and observation systems are...
...fixed in position.
...parfocal, meaning they focus on the same point.
...always used at the highest magnification.
...interchangeable with each other.
What is the purpose of the cobalt blue filter on a slit lamp?
To measure intraocular pressure.
To assess the depth of the anterior chamber.
To enhance the visibility of fluorescein dye.
To reduce patient discomfort.
Choose the CORRECT answer
The Galilean type of slit lamp only has 2 magnification options
All slit lamp using horizontal prism reflected light source
Slit lamp objective lens consists of 2 planoconvex lenses
Slit lamp consist of 2 main parts; observation and illumination system
All the following are the parts in illumination system EXCEPT
Filter
Lamp housing unit
Magnification changer
Difusser
The joystick on a slit lamp is primarily used for:
Changing the color of the light.
Adjusting the focus and position of the microscope.
Increasing and decreasing magnification.
Capturing images of the eye.
Choose the WRONG statement.
Red free filter is use to enhance the view of blood vessel and hemorrhages
A cobalt blue filter is used to enhance the view of fluorescein dye
Diffuser is used for good contrast enhancement
A neutral density filter decreases maximum brightness for photosensitive patients
Which of the following is NOT a part of the slit lamp's illumination system?
Slit aperture
Condensing lens
Ocular eyepieces
Diffuser
The usage of accessories lens helps in the following slit lamp assessment EXCEPT
Gonioscopy
Tonometry
Funduscopy
Perimetry
The best illumination to observe the depth of cornea would be
Wide beam
Parallelepiped
Optic Section
Diffuse
What is the main purpose of the chin rest and forehead band?
To make the patient more comfortable.
To keep the patient's head still and in the correct position.
To adjust the brightness of the light.
To measure the patient's interpupillary distance.
Which part of the eye is NOT typically visualized with a standard slit lamp without a special lens?
Eyelids and lashes
Cornea
Retina and optic nerve
Iris
The term "slit beam" in slit lamp biomicroscopy refers to:
The type of light bulb used.
The shape of the light beam projected onto the eye.
The magnification level of the microscope.
The color of the light used.
Choose the CORRECT statement about the importance of angle between the observation and illumination system.
5 degree angle allows the observation of depth only
45 degree angle allows observation of both surface and depth
85 degree angle gives better view of surface
10 degree angle allows the depth observation
Choose the BEST statement
Low magnification is used to observe cornea structure layers
Medium magnification is used to observe general eye structure
High magnification is used to observe epithelial changes
The higher the magnification the larger the field of view
What is the primary purpose of using fluorescein dye during a slit lamp examination?
To measure intraocular pressure
To enhance the visibility of the optic nerve
To detect corneal abrasions and other surface irregularities
To dilate the pupil
Which of the following is NOT a part of the observation system of a slit lamp?
Objective lenses
Eyepieces
Light source
Prisms
Choose the WRONG statement
Slit lamp is using Koehler illumination principle
Slit lamp is available in portable design
Slit lamp allows observation of retina
Slit lamp usually used to evaluate visual function
Which part of the slit lamp controls the brightness of the light source?
Rheostat
Joystick
Eyepiece
Chin rest
Choose the wrong description about slit lamp biomicroscopy.
Use to examine anterior part of the eye only
Consists of 2 eyepieces microscope
1st invented by Alivar Gullstrand
Can be used with other auxiliary lenses
Which of the following NOT the part of mechanical system of slit lamp?
Motorized table
Locking Control
Field size control
Fixation target
Which of these is a key step in preparing a patient for a slit lamp examination?
Having them lie down on a bed
Asking them to wear sunglasses
Properly positioning their head in the chin rest and forehead band
Asking them to close their eyes tightly
What is the main advantage of using a slit lamp for examination?
It is a quick and easy procedure to perform.
It allows for detailed, three-dimensional examination of the eye's structures.
It is a non-invasive procedure that does not require any contact with the eye.
It can be used to treat a wide range of eye conditions.
Which part of the eye can be observed with diffuse illumination?
Conjunctiva
Anterior chamber
Lens
Retina
