The retina is located between
choroid and inner limiting membrane
vitreous body and the choroid
retinal pigment epithelium and the vitreous body
outer limiting membrane and inner limiting membrane
the position of ora serrata is
between the equoator of the eyeball and scleral corneal junction
near the optic disc
close to the posterior pole of the eyeball
around the macula
By using the ophtalmoscope you will be able to explore the entire surface of the retina
T
F
The optic cup develops from
telencephalon
rhombencephalon
diencephalon
mesencephalon
The optic disc
is situated at the nasal part of the retina
have a pale color
is situated on the central part of the retina
is avascular
Macula lutea
have sharp margins
recive blood supply from central retinal artery
have a yellow color
measure around 5-6 mm
The cells of the retina are
Epithelial cells
Neuronal cells
Photoreceptor cells
Glial cells
The most outer layer of the retina is
external limiting membrane
retinal pigment epithelium
internal limiting membrane
nerve fiber layer
The most inner layer of the retina is
ganglion cells layer
nternal limiting membrane
nerve fiber layer
retinal pigment epithelium
The most common symptoms encountered in ophthalmic history are
Visual disturbance
Wateriness
Pain
Altered appearance
Monocular visual disturbance is represented by:
The lesion cannot be located in the vitreous body
The lesion is on the posterior visual pathway
The central nervous system is involved
The lesion is on the anterior visual pathways
Scotoma
it is a imprecisely delimited area of total reduction of vision surrounded by blind retina
it is a well-defined area of total or partial reduction of vision surrounded by the normal retina
it is a well-defined area of normal retina surrounded by blind retina
it is a white spot in the visual field
Metamorphopsia
is never present in optic nerve disease
it is a specific symptom of optic nerve pathology
Objects appear distorted
highly suggestive of the presence of macular disease
Flashing lights
it is a lens disorder
it is the result of retinal traction
is characteristic of macular pathology
it is an irritation of the visual pathways
Floaters represents
condensation of the vitreous
Opacities suspended in the vitreous gel
retinal traction
occasionally blood
Examination of the eyeball consists in
Central vision ( visual acuity)
External eye
Peripheral vision ( visual field)
Cover test
Slit lamp examination:
Eyeball examination method used in particular cases
The magnifying power may change during the examination
The most widely used method of examining the eyeballs
It only gives an overview of the eye structures
The components of the anterior segment of the eyeball are:
Cornea
Anterior chamber of the eyeball
The Pupil
The posterior vitreous
Diffuse illumination of the surface of the eyeball involves:
answer choices
Overall lighting with high magnification
Overview examination with low magnification
The spotlight is positioned at the edge of the structure concerned
The method is used for detailed examination of corneal lesions
The picture describes:
Hyphaema
Hypopyon
Tyndall phenomenon
Keratic precipitates
The image describes:
Hyphaema
Tyndall phenomenon
Hypopyon
Keratic precipitates
The image describes:
Tyndall phenomenon
Hypopyon
Post traumatic status
Keratic precipitates
The excretory system of the lacrimal apparatus is composed of:
Secondary lacrimal glands
Lacrimal ducts
Lacrimal sac
Nasolacrimal duct
Accessory lacrimal glands :
They are responsible for basic lacrimal secretion
They are responsible for reflex lacrimal secretion
Represent most of the tear secretion
They are represented by the Krause and Wolfring glands
Dry eye - Symptoms
burns
pain
foreign body sensation
photophobia
Non-surgical treatment of dry eye sdr.
Artificial tear instillations
Wet camera glasses
Devices that clog tear points
Omega 3 fatty acids
The inspection of the tear ducts can reveal:
Changes in the position of the lacrimal punctum
Inflammation of the lacrimal sac
Ectropion of the lower eyelid (internal orientation of the lower lacrimal punctum)
Entropion of the lower eyelid (external orientation of the lower lacrimal punctum)
Checking the permeability of the tear ducts is done by:
Imaging examination
Syringing of lacrimal tract
Probing of lacrimal tract
Instillation of a colored solution in the inferior fornix
Syringing of lacrimal tract:
It is performed under local anesthesia
It is performed under general anesthesia in adults
It is made with the help of the Bowman conical instrument
It is made using a cannula adapted to a 5ml syringe that contains a mixture of Ringer's, betadine and xylin.
Schirmer I test:
Evaluates basal secretion and reflex secretion
It does not require local anesthesia
Normal> 15mm in 5 minutes
Normal> 5mm in 5 minutes
