What causes neuroretinitis?
Neuroretinitis is inflammation of the retina and optic nerve of the eye. The condition can be caused by bacteria, viruses or autoimmune disease. It shares some features of optic neuritis. There is mostly central visual loss, which often recovers after some months, but often not completely.
Does neuroretinitis go away?
At 8-12 weeks, the disc edema has resolved, leaving a normal or pallorous nerve. Most patients with idiopathic neuroretinitis recover excellent visual acuity with or without intervention: 20/40 or better in 90% of reported cases.
What causes a macular star?
Macular star formation is caused by the deposition of lipid exudates along the outer plexiform layer of the macula. Few disorders such as neuroretinitis, hypertensive retinopathy and papilloedema are associated with lipid deposits with this peculiar pattern.
What is macula star?
Optic disk edema with a macular star is a descriptive term encompassing a heterogeneous group of disorders. The clinical features include sudden visual loss, swelling of the optic disk, peripapillary and macular exudates that may occur in a star pattern, and cells in the vitreous.
What causes a macular scar in the eye?
Most of the time, a macular pucker happens because of normal changes in your eye when you get older. As you age, your vitreous — the clear gel that fills your eye and gives it a round shape — shrinks and pulls away from your retina (the light-sensitive layer of tissue in the back of the eye).
How long does hypertensive retinopathy last?
The retinal changes can be halted when hypertension is treated. However, arteriolar narrowing and AV changes persist. For untreated malignant hypertension, the mortality is high as 50% within 2 months of diagnosis and almost 90% by the end of 1 year.
What causes morning glory in the eyes?
MGS seems to be caused from failure of the optic nerve to completely form when the baby is developing. The most severe complication is retinal detachment, and can occur in about 26-38% of people with MGS. The MGS is sometimes misdiagnosed as an optic nerve coloboma.”
What is bilateral Neuroretinitis?
Neuroretinitis is a clinical syndrome characterized by abrupt visual loss, optic nerve swelling, and a macular star exudate.
How do you treat macular scars?
Treatment: Macular Pucker Surgery to Remove Scar Tissue The outpatient surgery is done with local anesthesia and involves removing the vitreous (vitrectomy) and usually peeling off the cellophane-like scar tissue.
Can a scarred retina be fixed?
A retinal tear or a detached retina is repaired with a surgical procedure. Based on your specific condition, your ophthalmologist will discuss the type of procedure recommended and will tell you about the various risks and benefits of your treatment options.
Can you reverse hypertensive retinopathy?
Q: Can hypertensive retinopathy be reversed? A: It depends on the extent of damage to the retina. In many cases, the damage caused by hypertensive retinopathy can slowly heal if the necessary steps to lower one’s blood pressure are taken.
What are the signs of stage 4 hypertensive retinopathy?
The signs include flame shaped hemorrhages at the disc margin, blurred disc margins, congested retinal veins, papilledema, and secondary macular exudates. Hard exudates can deposit in the macula causing a macular star. Optic nerve pallor is also present in patients with chronic hypertension.
Is swollen optic nerve serious?
Papilledema is swelling of your optic nerve, which connects the eye and brain. This swelling is a reaction to a buildup of pressure in or around your brain that may have many causes. Often, it’s a warning sign of a serious medical condition that needs attention, such as a brain tumor or hemorrhage.
What medications can cause optic nerve swelling?
Causes of toxic optic neuropathy include chemicals and drugs, such as methanol, ethylene glycol, ethambutol, isoniazid, digitalis, cimetidine, vincristine, cyclosporine, toluene, and amiodarone.
Can Vitamin B12 deficiency cause optic neuritis?
Vitamin B12 (VitB12) deficiency rarely manifests with visual symptoms. Optic nerve damage in VitB12 deficiency is thought to be via degeneration. However, optic neuritis, though infrequent, has been reported secondary to VitB12 deficiency.
Can you fix Morning Glory Syndrome?
Management. 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.
How common is Morning Glory Syndrome?
Morning glory syndrome (MGS) is a congenital optic disc anomaly. It was named by Peter Kindler who observed that the fundus resembled a blossoming morning glory [1]. The prevalence of MGS has been reported to be 2.6/100,000 [2].
