Slit Lamp Biomicroscopy Quiz

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
