REVIEW
Rosanna Dammacco
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of undefined etiology and with remarkably heterogeneous clinical features. Virtually any organ system can be affected, including the eye. SLE-related eye involvement can be diagnosed in approximately one-third of the patients and is usually indicative of disease activity. An early diagnosis and the adoption of suitable therapeutic measures are necessary to prevent sight-threatening consequences, especially in patients with juvenile SLE. Periocular lesions, such as eyelid involvement and orbital inflammation, are relatively rare and, in case of orbital masses, may require a biopsy control...

Background: Multiple sclerosis and other demyelinating processes are sometimes difficult to differentiate from the neurological involvement in autoimmune diseases. Distinguishing multiple sclerosis from other lesions due to autoimmune diseases is crucial to avoid unsuitable or delayed treatments. Methods: Charts of 6 patients diagnosed with mimicking multiple sclerosis between 1996 and 2014 were retrospectively assessed. Results: The mean age at diagnosis was 35±7 years...

Autoantibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have been reported in patients with inflammatory central nervous system disorders including isolated optic neuritis (ON). We compared our MOG-IgG ON patients with multiple sclerosis (MS) patients presenting with ON. METHODS AND RESULTS: Among the total of 38 patients with optic neuropathies, six patients with isolated ON were MOG-IgG positive and eight patients with ON fulfilled the diagnostic criteria for MS. All MS patients were negative for MOG-IgG using a cell-based assay...

A 6-year-old neutered female Jack Russell terrier was investigated for sudden onset prechiasmatic bilateral blindness, left circling, reduced proprioception in the right pelvic limb and right facial allodynia. Electroretinography was normal. Magnetic resonance imaging (MRI) examination revealed that the right optic nerve and the optic chiasm were hyperintense on diffusion weighted imaging and hypointense on apparent diffusion coefficient map consistent with ischemic optic neuropathy. A concurrent lacunar infarct was detected in the left rostral colliculus...

AIMS: We set out to determine the optical coherence tomographic angiography (OCT-A) characteristics of arteritic anterior ischaemic optic neuropathy (AAION) in the context of giant cell arteritis (GCA). METHODS: This is an observational case series of four patients with AAION secondary to GCA, three with unilateral AAION and one with bilateral AAION. We reviewed the charts, fundus photography, visual fields, fluorescein angiography (FA) and OCT-A images for all patients to identify a unifying theme in a range of AAION clinical severity...

SIGNIFICANCE: Large-vessel giant cell arteritis (GCA) can be a diagnostic dilemma for the eye care provider because it may not involve the typical cranial arteries. When any of its potential ocular complications are diagnosed, it is important to consider this unusual form of GCA. PURPOSE: To report an unusual ophthalmic presentation of large-vessel GCA with sequential bilateral anterior ischemic optic neuropathy and branch retinal artery occlusion. METHODS: A 65-year-old previously healthy woman experienced sequential bilateral anterior ischemic optic neuropathy with branch retinal artery occlusion in the absence of other signs and symptoms suggestive of cranial GCA...

BACKGROUND: Leukemic infiltration of the optic nerve is relatively rare. While previously described in acute leukemia, the infiltration in our case represents central nervous system (CNS) metastasis of Burkitt-type lymphoma that developed as a complication of solid-organ transplantation, resulting in a bilateral infiltrative optic neuropathy with sequential, bilateral central retinal artery occlusion (CRAO) and devastating vision loss. METHODS: The medical record, serial ophthalmic examination findings, clinical course, and imaging including magnetic resonance imaging (MRI), fundus photographs, and fluorescein angiography of a single patient were retrospectively reviewed...

Anemia appears frequently in patients with alcoholic liver disease (ALD) but has never been linked to bilateral nonarteritic anterior ischemic optic neuropathy (NAION). A 65-year-old woman with a medical history of alcoholic cirrhosis was admitted for bilateral NAION. On admission, she was found to have a low arterial pressure and severe normocytic anemia (48 g/L). The anemia was related to chronic bleeding due to antral gastritis along with other factors associated with ALD. The applied treatment consisted of urgent transfusion followed by high doses of proton-pump inhibitors, iron and vitamin supplementation, and support in lifestyle measures...

BACKGROUND: We describe a 75-year-old woman who experienced vision loss in her left eye due to biopsy-proven giant cell arteritis (GCA). She subsequently developed pachymeningitis causing refractory headaches and bilateral optic neuropathy and maculopathy. METHODS: Case report with literature review. RESULTS: Eighteen months after the initial diagnosis of GCA, imaging studies in our patient demonstrated pachymeningeal enhancement, and meningeal biopsy confirmed lymphoplasmacytic tissue infiltrates with low frequencies of IgG4+ plasma cells...

OBJECTIVES: To summarise and discuss recent findings and future perspectives concerning mitochondrial disorders (MIDs) affecting the retinal ganglion cells and the optic nerve (mitochondrial optic neuropathy. MON). METHOD: Literature review. RESULTS: MON in MIDs is more frequent than usually anticipated. MON may occur in specific as well as non-specific MIDs. In specific and non-specific MIDs, MON may be a prominent or non-prominent phenotypic feature and due to mutations in genes located either in the mitochondrial DNA (mtDNA) or the nuclear DNA (nDNA)...

Sarcoidosis is one of the leading causes of inflammatory eye disease. Any part of the eye and its adnexal tissues can be involved. Uveitis and optic neuropathy are the main manifestations, which the internists face. This review reports the state of knowledge for these two ocular involvements and proposes an assessment-algorithm for sarcoidosis in patients with suspected sarcoid uveitis. Two groups of patients with sarcoid uveitis can be distinguished: one young and multiethnic group in which ophthalmological findings are various and another group of elderly Caucasian women with mostly chronic posterior uveitis...

A 71-year-old woman was admitted with fever, headache, and weight loss associated with elevated inflammatory markers. She developed acute bilateral ophthalmoplegia and asymmetrical ptosis, rapidly followed by anterior ischemic optic neuropathy. Although the first temporal artery biopsy was negative, contralateral temporal artery biopsy revealed features consistent with giant cell arteritis. Even while under steroid therapy, she died a few days later from myocardial infarction. Acute bilateral complete ophthalmoplegia is a rare presentation of a limited number of possible diseases...

BACKGROUND: Methanol toxicity poses a significant public health problem in developing countries, and in Southeast Asia, where the most common source of poisoning is via adulterated liquor in local drinks. Methanol toxicity can have devastating visual consequences and retinal specialists should be aware of the features of this toxic optic neuropathy. The authors report a case of severe systemic methanol toxicity and relatively mild optic neuropathy demonstrating unique retinal changes on optical coherence tomography (OCT)...

A 50-year-old female presented with bilateral retinitis pigmentosa (RP) and acute angle closure (AAC) with fixed mid-dilated pupil and high intraocular pressure (IOP) in the left eye following left side periorbital botulinum toxin A injection for blepharospasm. Glaucomatous optic neuropathy and retinal nerve fiber layer defect were observed in the affected eye using optical coherence tomography although the IOP was maintained at <21 mmHg after the treatment. Botulinum toxin acts at the cholinergic synapse and inhibits acetylcholine release; hence, it can cause transient mydriasis and may lead to AAC in high-risk populations such as patients with RP...

Leber hereditary optic neuropathy (LHON) is a maternally inherited, bilateral, sequential optic neuropathy that usually affects young males. LHON arises from a defect in complex I of the oxidative phosphorylation chain that generates increased reactive oxygen species and causes a decline in cellular ATP production. There exists no cure at present for LHON. Asymptomatic LHON mutation carriers show signs of increased mitochondrial biogenesis that may compensate for the compromise in complex I activity. Partial recovery in LHON is associated with a wider optic disc diameter and a younger age at disease onset, which may allow for greater mitochondrial bioenergetic capacity...
