The tilted disc syndrome was first clearly de- scribed in 1944 (Rucker 1944). It is
a benign optic disc anomaly where the optic nerve enters the eye at an angle other than a right angle
. The disc looks oval and lopsided, usually elevated superiorly and depressed inferiorly.
What causes tilted optic disc?
Tilted optic discs often arise due
to acquired changes related to the progression of myopia
, known as myopic tilted disc. Because tilted disc syndrome arises from a congenital anomaly, the signs are considered nonprogressive. However, as an acquired condition, myopic tilted disc is often progressive.
What does tilted optic disc mean?
Tilted optic disks are a common finding in the general population.
An expression of anomalous human development
, the tilted disk appears rotated and tilted along its axes. Visual sequelae described with tilted optic disks include myopia, astigmatism, visual field loss, deficient color vision, and retinal abnormalities.
Is tilted disc syndrome hereditary?
Disease Entity
Tilted disc syndrome (TDS), also known as Fuch’s Coloboma, is a congenital anomaly that occurs in 1 to 2% of the population. While mostly understood as a nonhereditary process,
reports of autosomal dominant inheritance exist
.
What causes morning glory in the eyes?
Morning glory syndrome (MGS) is a
birth ( congenital ) defect of the nerve of the eye (optic nerve)
that resembles a flower known as “morning glory”. It is characterized by an enlarged, funnel-shaped cavity of the optic disc, the point in the eye where the optic nerve fibers leave the retina.
What are signs of optic nerve damage?
- Abnormal pupil size and nonreactivity to light.
- Bulging of the eyes.
- Complete or partial loss of vision.
- Diminished ability to see fine details.
- Diminished color vision or colors seem faded.
- Dimming or blurring of vision.
- Double vision.
- Eye redness.
Can high myopia cause glaucoma?
High myopia is associated with an increased risk of
pathological
ocular complications and may lead to blinding disorders such as premature cataracts, glaucoma, retinal detachment, and macular degeneration[18].
What is a tilted nerve in the eye?
Tilted disc syndrome (Fuch’s Coloboma): a
congenital abnormality (birth defect) of the eye that causes the optic nerve to enter the retina
(this area is called the optic disc) at an abnormal angle. In tilted disc syndrome, the abnormal entry of the optic nerve causes an abnormal position and angle of the optic disc.
What is tessellated fundus?
Tessellated fundus is defined as
the condition in which the choroidal vessels can be seen through the retina owing to reduced pigmentation or hypoplasia of the retinal pigment epithelium
(RPE) [13].
What is lacquer cracks?
Lacquer cracks are
breaks in Bruch’s membrane frequently observed in the posterior pole of a highly myopic eye
. These distinctive fundus changes are actually quite common in axial myopia and may augur hemorrhage into the macular area, either from mechanical causes or from choroidal neovascularization.
What is lamina Cribrosa?
The lamina cribrosa (LC) is
a reticulated, sieve-like structure that fills the posterior scleral foramen
, which unmyelinated retinal ganglion cell (RGC) axons pass through before converging as the optic nerve (ON).
What is Colomba eye?
Mar. 18, 2020. A coloboma describes
conditions where normal tissue in or around the eye is missing at birth
. Coloboma comes from the Greek word that means “curtailed.” The eye develops quickly during a fetus’ first three months of growth.
What is high myopia?
The term “high myopia” is generally used to describe a
refractive measurement of -6.00 diopters or higher
. For reference, mild nearsightedness usually falls between -0.25 and -3.00 diopters. Nearsightedness usually occurs as the result of a slightly elongated eyeball shape.
Is there a cure for morning glory syndrome?
There is no treatment for morning glory disc anomaly
. However it is important to optimize visual acuity to prevent amblyopia. Dilated fundus exams should be done to detect serous retinal detachments that tend to originate in the peripapillary area and extends to the posterior pole.
Why do we have eye boogers?
Eye boogers refer to
a buildup of mucus in the eyes
. During the day, each time a person blinks, the eyes flush away the secretions of rheum they have produced. Since the eyes produce this mucus in such small quantities, most people never notice it. At night, when a person does not blink, the mucus can build up.
What is morning glory slang?
Morning glory More than a flower, this slang term has existed since the early 1900s and has meant “
something which or someone who fails to maintain an early promise
” as well as, in the 1950s, “the first narcotic injection of the day.”
