Do you know about ophthalmology? Why don't you take these ophthalmic quiz questions and answers and test your knowledge right here right now? Ophthalmology is understood as a surgical subspecialty within medicine to deal with the diagnosis and treatment of eye disorders. An ophthalmologist is known as a physician who undergoes subspecialty training as well as surgical eye care. Take these questions, and you will learn even more about this. Let's go for it!
Diffuse beam
Low Mag
Medium Mag
Low to moderate illumination
Optic section
Meibomitis
GPC
Capped glands
Trichiasis
Dellen
Axenfeld's Loop
Concretions
Superficial Punctate Keratitis
Krukenberg's Spindle
Diffuse
Sclerotic
Specular
Indirect
Beam angle : 60 degrees to variable
Illumination : medium
Magnification : high
Beam width: small parallelepiped
Is used only for cornea
Is a zone of illumination that utilizes light bounced off another structure
Will allow objects that are clear to appear light.
Will allow objects that are opaque or light to appear dark.
Requires magnification between medium to high
Is a type of direct focal illumination
Is used primarily for cornea
Requires high magnification for proper use
Provides a 3D view
Has two parallel sides
Conical beam
Sclerotic scatter
Optic section
None of these
Is used to evaluate the lens vacuoles, cataracts, Y-suture
Is the most commonly used method of evaluating structures
Requires high illumination
Provides a 2D view: of height and depth
Is used to localize the depth of defects
Cornea: to determine the depth of the lesion
Cornea: to determine the health of the endothelium
Angle estimation
Anterior chamber evaluation
Len
True
False
Judges the quality of a surface
Is viewed binocularly
Angle of incidence of the beam of light from the slit lamp equals the angle of reflection of light into the biomicroscope.
Can be used to evaluate many structures: lens, iris, cornea
Has a beam width of the optic section
Can be used to evaluate corneal nerves, scares, neovascularization
Magnification: low to medium
Zone of illumination that is adjacent to the direct focal beam
Darkens abnormalities
Is a type of direct illumination
Is when light is directed at the limbus to scatter light internally throughout the cornea
Is a fantastic diagnostic tool
The beam is positioned at the nasal limbus
Direct retro illumination can be used to evaluate transillumination defects on the iris
Direct retro illumination can be used to evaluate a posterior sclerotic cataract
Focusing problems on a slit lamp may be due to the examiner accommodating or a patient's head falling away from the headrest.
Indirect retro illumination requires high magnification and high illumination
Low illumination
Medium illumination
Diffuse beam
Medium parallelepiped
High magnification
Medium magnification
Wide parallelepiped
A hemorrhage due to trauma or a Valsalva maneuver
Translucent inclusion cysts
Chemosis
None of these
Infiltrations of the WBC, proteins, debris, and cells
Edema
Pinpoint cysts
Epithelial surface irregularities
Dystrophies
Persistent Pupillary Membrane
Keratitis Precipitates
True
False
It is often associated with a past history of trauma and improper healing.
It is a dry, thinner depressed spot at the peripheral cornea.
It is often associated with dry eye, SPK, and surface irregularities.
You would assess this condition using High illumination, moderate magnification, lighthouse located at 60 degrees, and an optic section.
It appears as white, thinned and moth-eaten under high magnification.
