Flat optic nerve

Optic atrophy is a condition that affects the optic nerve, which carries impulses from the eye to the brain. (Atrophy means to waste away or deteriorate.) Optic atrophy is not a disease, but rather a sign of a potentially more serious condition. Optic atrophy results from damage to the optic nerve from many different kinds of pathologies The normal optic nerve has a healthy appearing rim of tissue, which is assessed by both the contour of the rim as well as the color. Cupping is the result of changes in the optic nerve related to optic nerve degeneration, where there is a backward bowing of the central part of the disc

A normal optic nerve head (ONH) usually is round or oval, mildly elevated and pink in color, with a centralized depression known as the cup. The horizontal diameter of a typical optic nerve is approximately 1.5mm. 1 1. Melanocytoma with adjacent choroidal, retinal components and mild yellow exudation Size and shape The optic nerve head or disc comes in a variety of shapes andsizes. The mean average Caucasian optic disc area, excludinghigh myopes, is between 2.1mm2and 2.8mm2with a range <Figure 1 small, flat optic nerve head of a young Caucasian patien A mesh of nerves and fibers surrounds your optic nerve, so it's always in the right spot. If that network dies, your doctor will see a cup-like space around your optic nerve in the back of your eye. The Glaucoma Research Foundation says glaucoma is a common cause of optic cupping The optic nerve begins at the optic disk, a structure that is 1.5 mm (0.06 inch) in diameter and is located at the back of the eye. The optic disk forms from the convergence of ganglion cell output fibres (called axons) as they pass out of the eye Optic atrophy, pallor of the optic nerve head, is a sign found in patients with visual loss due to pathology of the optic nerve or retinal ganglion cells. There are many causes. This article discusses the differential diagnosis of optic atrophy. Open in a separate windo

Brain and nervous system disorders that can cause eye twitching include: Bell's palsy. Cervical dystonia. Dystonia. Multiple sclerosis. Oromandibular dystonia and facial dystonia. Parkinson's disease. Tourette syndrome. Eye twitching may be a side effect of drugs, particularly medication used for Parkinson's disease It's the most common form of optic nerve damage leading to vision loss. In most cases, fluid builds up in the front part of the eye. This extra fluid puts pressure on the eye, gradually damaging the optic nerve. This pressure is known as intraocular pressure (IOP), or eye pressure

  1. Normally, the optic nerve is around 1.5mm in diameter horizontally, it is either oval or round in shape and has defined margins with a pink neural retinal rim. It is very slightly raised with the middle area known as the cup dipping in slightly. Depending on the cup size and depth, the amount of centralized depression varies
  2. The normal optic nerve head (optic disc) usually is round or oval and pink in color; typically it is flat or mildly elevated and has a central depression called the cup (picture 1). The horizontal diameter of the normal optic nerve is approximately 1.5 mm
  3. Optic nerve head protrusion and globe flattening were significantly associated with IIH. There was no statistically significant difference in the occurrence of rest of the findings. On subgroup analysis, globe flattening and optic nerve head protrusion occurred significantly more often in IIH than in tumors

Restore Vision Clinic in Germany treats vision loss caused optic nerve damag The optic nerve carries impulses for sight from the retina in the eye to the brain. It is composed of millions of retinal nerve fibers that bundle together and exit to the brain through the optic disc located at the back of the eye. The optic disc has a center portion called the cup which is normally quite small in comparison to the entire. Marfan syndrome is an inherited disorder that affects connective tissue — the fibers that support and anchor your organs and other structures in your body. Marfan syndrome most commonly affects the heart, eyes, blood vessels and skeleton. People with Marfan syndrome are usually tall and thin with unusually long arms, legs, fingers and toes

Optic atrophy refers to the death of the retinal ganglion cell axons that comprise the optic nerve with the resulting picture of a pale optic nerve on fundoscopy. Optic atrophy is an end stage that arises from myriad causes of optic nerve damage anywhere along the path from the retina to the lateral geniculate. Since the optic nerve transmits retinal information to the brain, optic atrophy is. ↑ E.F. Krug, B. Samuels Venous angioma of the retina, optic nerve, chiasm and brain.

Blanc L'anévrysme cirsoïde de la face et avec l'anévrysme cirsoïde du cerveau J Méd Lyon, 18 (1937), pp. 165-17 The optic nerve is part of the central nervous system and cannot regenerate or repair itself because of natural inhibitors in the body that block its re-growth. Various alternative approaches to try to stimulate nerve fibre growth are under research, but their success depends on stopping natural inhibitors from working

Optic nerves have dimples in them called cups. We make a ratio(the cup to disk ration or C/D) The C/D is the ration of the width of the cup to the hold optic nerve and goes from zero (totally flat optic nerve head) to 100% (a cupped out nerve due to end stage glaucoma Funduscopy of the patient's right eye showed a pink, flat optic nerve with sharp margins and a cup-to-disc ratio of 0.2. The left disc was flat and sharp, with central pallor and a cup-to-disc ratio of 0.9. Based on these findings, we determined that the patient's elevated IOP was due to pseudoexfoliation glaucoma Optic neuritis is a condition in which the nerve that connects the eyes and brain becomes inflamed and swollen. a flat-looking cheek, possibly with severe pain while opening the mouth. Radial nerve injury can lead to wrist drop - the inability to straighten the wrist. The radial nerve also provides sensation to the thumb side of the back of the hand. Median nerve.

His mother reported that vision problems had been noted at school, and she expressed concern that.

Aplasia of the optic nerve is an extraordinarily rare congenital anomaly that affects one or both optic nerves and is associated with the absence of the central retinal vessel and retinal ganglion cells. We report a case of unilateral optic nerve aplasia in a 4-month-old infant who was found to have left microphthalmos on routine postnatal checkup Rare bilateral tumors may be associated with optic nerve hypoplasia and central nervous system abnormalities. The majority of patients are asymptomatic, and the tumors are diagnosed on a routine examination. Optic disc melanocytoma has the characteristic ophthalmoscopic appearance of a dark black, flat,.

Optic Nerve Atrophy/Degeneration.

Optic disc. Ophthalmoscopically, there is a wide variation in optic disc appearance in the population (Bengtsson 1976; Varma et al. 1994), with refraction and eye size among the parameters that are possibly of influence. Therefore, a small and dense 'hyperaemic' disc is often described as being typical of high hypermetropia, in contrast to. laterally flat optic nerve discs with clear margins. Cello-phane maculopathy was present in her OD. After ophthalmic tests, her clinicians arranged follow-up examinations within a month.
