PRESENTED BY
OM VERMA
ASSISTANT PROFESSOR
INTRODUCTION
Inflammation of the uveal tract (iris, ciliary
body, and choroid) has many potential
causes, including infections (toxoplasmosis,
causes, including infections (toxoplasmosis,
herpes zoster and simplex, and Lyme
disease), collagen vascular disease and
trauma. Then lead the uveal disorders.
Definition
Any abnormality of The middle layer of the wall ( uveal tract )
of the eye. It is called disorders of uveal tract.
According to AND
According to AND
Cluster of disease of uveal tract consists of the choroid, ciliary
body, and iris uveal tract it is called disorders of uveal tract
According to lippen cott
Uveitis is inflammation of the
middle layer of the eye, the
uvea, and surrounding tissue.
It can be painful, the eye or
It can be painful, the eye or
eyes may be red, and vision
can be cloudy.
Auto immune disorders
Neuromyelitis optica is an autoimmune
disorder that affects the nerves of the
eyes and the central nervous system,
eyes and the central nervous system,
which includes the brain and spinal cord.
Autoimmune disorders occur when the
immune system malfunctions and
attacks the body's own tissues and
organs.
Toxoplasmosis
Toxoplasmosis is a flu-like disease caused by a
single-celled parasite called Toxoplasma
gondii. results from infection with a common
parasite found in cat faeces and contaminated
parasite found in cat faeces and contaminated
food. It can cause serious complications for
pregnant women and people with weakened
immune systems.
And affect the uveal tract Symptoms include
muscle pain, fever and headache,
HSV (Herpes Simplex Virus)
HSV lead the keratitis is an
infection of the cornea more
infection of the cornea more
severe infections can lead to
scarring of the cornea or
blindness Uveitis.
OCCULAR CANDIDITIS
Fungal eye infection symptoms are similar to
those of other types of eye infections (like
those caused by bacteria) and can include:
Eye pain.
Eye redness.
Eye redness.
Blurred vision.
Sensitivity to light.
Excessive tearing.
Eye discharge.
HISTOPLASMOSIS,
it is a fungal infection the infection can
move from the lungs into the eyes,
leading to vision loss
leading to vision loss
Tuberculous uveitis is a rare condition
caused by Mycobacterium tuberculosis.
Involvement of the uveal tract is the
most common manifestation of the
disease, and findings of granulomatous
anterior uveitis,
anterior uveitis,
Syphilis is an infectious disease caused by
Treponema Pallidum and is most commonly
spread through sexual transmission. Syphilitic
uveitis
Granulomatous uveitis
Is An Inflammation Of The Uveal
Tract Characterized By The
Tract Characterized By The
Formation Of Granulomas Due To
Infectious Or Non-infectious
Causes
UVEAL MELANOMA
UVEAL MELANOMA
Uveal melanoma of the iris is usually a
small tumor that grows slowly and
rarely spreads to other parts of the
body. Uveal melanoma of the ciliary
body and choroid are usually larger
body and choroid are usually larger
tumors and are more likely to spread
to other parts of the body. Uveal
melanoma is the most common type
of eye cancer in adults.
ANIRIDIA
Aniridia is an eye disorder characterized by a
complete or partial absence of the colored
part of the eye (the iris).
In addition to missing irises, symptoms of
aniridia include:
aniridia include:
Eye pain.
Low vision.
Light sensitivity.
Blindness or partial vision loss in one or both
eyes.
ALBINISM
Albinism it is a congenital
defect characterized by
absence of melanin skin and
absence of melanin skin and
eye .
Clinical manifestration
@eye pain and redness
@general vision problems,
including blurred or cloudy
vision
vision
@photophobia, an abnormal
sensitivity to light
@headaches
@ Dark, floating spots in your
field of vision (floaters).
@ retinal hemorrhage
DIAGNOSTIC EVALUATION
DIAGNOSTIC EVALUATION
Assessment of vision (with your glasses if you normally
wear them) and the response of your pupils to light.
Tonometry. A tonometry exam measures the pressure
inside your eye (intraocular pressure). Numbing eyedrops
may be used for this test.
A slit-lamp examination. A slit lamp is a microscope that
magnifies and illuminates the front of your eye with an
intense line of light. This evaluation is necessary to
intense line of light. This evaluation is necessary to
identify microscopic inflammatory cells in the front of the
eye.
Ophthalmoscopy. Also known as funduscopy, this exam
involves widening (dilating) the pupil with eye drops and
shining a bright light into the eye to examine the back of
the eye.
Color photography of the inside of the eye (retina).
Optical coherence tomography (OCT) imaging. This test
maps the retina and choroid to reveal swelling in these
layers.
Fluorescein angiography or indocyanine green
angiography. These tests require placement of an
intravenous (IV) catheter in a vein in your arm in order to
give a dye. This dye will reach the blood vessels in the
give a dye. This dye will reach the blood vessels in the
eyes and allow photographs of swollen blood vessels
inside the eyes.
Analysis of aqueous or vitreous fluid from the eye.
Blood tests.
Imaging tests, radiography, CT or MRI scans.
Medications
Drugs that reduce inflammation. Your
doctor may first prescribe eye drops with
an anti-inflammatory medication, such as a
corticosteroid. Eye drops are usually not
enough to treat inflammation beyond the
enough to treat inflammation beyond the
front of the eye, so a corticosteroid
injection in or around the eye or
corticosteroid tablets (taken by mouth) may
be necessary.
Uveitis can be treated with steroid
medicine. A medicine called
prednisolone is usually used. Steroids
work by disrupting the normal
function of the immune system so it
function of the immune system so it
no longer releases the chemicals that
cause inflammation.
Drugs that fight bacteria or viruses.
If uveitis is caused by an infection, doctor may
prescribe antibiotics, antiviral medications or
other medicines,, Systemic antivirals—
acyclovir, famciclovir or valacyclovir—are the
acyclovir, famciclovir or valacyclovir—are the
primary treatment because they protect the
cornea as well as treat the uveitis. to bring
the infection under control.
Drugs that affect the immune system
or destroy cells.
You may need immunosuppressive
drugs if your uveitis affects both eyes,
doesn't respond well to corticosteroids
doesn't respond well to corticosteroids
Immunosuppressive Agents
Antimetabolites. Azathioprine. Methotrexate.
T-cell inhibitors. Cyclosporine
MYDRIATIC EYEDROPS
as well as steroid medicine.
cyclopentolate These eyedrops enlarge
(dilate) your pupils and relieve pain by
relaxing the muscles in your eye. They
relaxing the muscles in your eye. They
can also reduce your risk of developing
glaucoma, which affects vision.and
uveal tract disorders
COMPLICATIONS
Retinal swelling (macular edema).
Retinal scarring.
Glaucoma.
Cataracts.
Cataracts.
Optic nerve damage.
Retinal detachment.
Permanent vision loss.
