Curr Eye Res 2021 May 12. Epub 2021 May 12.

Eye Research Center, The Five Senses Institute, Rassoul Akram Hospital, Iran University of Medical Sciences, Tehran, Iran.

Introduction: To compare the optic nerve head (ONH) structure and microvasculature in patients with optic atrophy due to non-arteritic anterior ischemic optic neuropathy (NAION), compressive optic neuropathy (CON), methanol-induced optic neuropathy (MION), and traumatic optic neuropathy (TON) using optical coherence tomography angiography.

Teprotumumab: The Dawn of Therapies in Moderate-to-Severe Thyroid-Associated Ophthalmopathy.

Horm Metab Res 2021 Apr 14;53(4):211-218. Epub 2021 Apr 14.

Department of Endocrinology and Metabolism, Tianjin Medical University General Hospital, Tianjin, China.

Thyroid-associated ophthalmopathy (TAO) is a potentially sight-threatening ocular disease. About 3-5% of patients with TAO have severe disease with intense pain, inflammation, and sight-threatening corneal ulceration or compressive optic neuropathy. The current treatments of TAO are often suboptimal, mainly because the existing therapies do not target the pathogenesis of the disease. Read More

The role of optical coherence tomography in the diagnosis of afferent visual pathway problems: A neuroophthalmic perspective.

Handb Clin Neurol 2021 ;178:97-113

Departments of Ophthalmology and Neurology, Mayo Clinic, Rochester, MN, United States.

Optical coherence tomography (OCT) is a noninvasive ocular imaging technique that has become a standard tool in neuroophthalmic practice. Specifically, OCT captures retinal manifestations of neuroaxonal injury caused by lesions along anterior and posterior regions of the afferent visual pathway, in patients presenting with vision loss. More recently, the advent of OCT angiography (OCTA) has enabled evaluation of the choroidal and retinal microvasculature, thus informing our understanding regarding vascular mechanisms associated with optic nerve and retinal injuries.

Electrophysiology in neuro-ophthalmology.

Handb Clin Neurol 2021 ;178:79-96

UCL Institute of Ophthalmology, University College London, London, United Kingdom; Department of Electrophysiology, Moorfields Eye Hospital NHS Foundation Trust, London, United Kingdom. Electronic address:

This chapter reviews common applications of visual electrophysiology relevant to neuro-ophthalmology practice. The use of standard tests and extended protocols are described including the cortical visual evoked potential and pattern and full-field electroretinogram (PERG; ERG) methods, the latter including the photopic negative response. Abnormalities of these recordings are rarely specific but provide valuable diagnostic guidance and an objective measure of visual pathway function, difficult or impossible to infer by other methods.

Compressive optic neuropathy (CON) in Graves' disease caused by hypertrophy of levator and superior rectus muscles: A case report.

Medicine (Baltimore) 2021 Apr;100(14):e25062

Department of Ophthalmology, Osaka Medical College, Osaka, Japan.

Rationale: Enlargemento of the medial rectus is the most predominant factor of compressive optic neuropathy (CON) in Graves' disease. This case report indicates that CON could develop only from the hypertrophic superior levator and superior rectus (SL/SR) muscle in a patient with poorly controlled Graves' disease, and described the possible risk of FT3-thyrotoxicosis with a prominent goiter to develop the current rare case with a review of the literature.

Patient Concerns: A 66-year-old woman undergoing endocrine management of hyperthyroidism with prominent goiter visited the Department of Ophthalmology due to right-eye upper-eyelid retraction. Read More

Approach to patient with unilateral optic disc edema and normal visual function.

J Neurol Sci 2021 05 24;424:117414. Epub 2021 Mar 24.

University of Toronto, Faculty of Medicine, Department of Ophthalmology and Vision Sciences, Toronto, Ontario, Canada; University of Toronto, Faculty of Medicine, Department of Medicine, Division of Neurology, Toronto, Ontario, Canada. Electronic address:

In patients with swollen optic nerve head and normal visual function, optic disc drusen (ODD) is the most common diagnosis. The best tests for detecting ODD are funds autofluorescence and enhanced-depth imaging ocular coherence tomography (EDIOCT). After ODD has been ruled out, asymmetric papilledema should be assumed to be the cause and MRI of the brain and orbits with contrast and venography should be performed in all patients. Read More

Meningiomas of the Planum Sphenoidale and Tuberculum Sella.

J Neurol Surg B Skull Base 2021 Feb 12;82(1):72-80. Epub 2021 Feb 12.

Department of Ophthalmology, Sue Anschutz-Rodgers UCHealth Eye Center, University of Colorado School of Medicine, Aurora, Colorado, United States.

Patients with meningiomas of the planum sphenoidale and tuberculum sella often present with insidious vision loss in one or both eyes as the only sign or symptom of their disease, although other sensory, oculomotor, and even endocrine abnormalities may be seen in a minority of cases. Incidentally discovered tumors also are common, as patients may undergo neuroimaging for unrelated symptoms or events. Depending on the size and orientation of the tumor, central vision loss from optic nerve compression may be a later sign, and loss of peripheral vision in one or both eyes may not be recognized until it has progressed to areas closer to fixation.

Rescue of retinal ganglion cells in optic nerve injury using cell-selective AAV mediated delivery of SIRT1.

Gene Ther 2021 Feb 15. Epub 2021 Feb 15.

University of Pennsylvania/Ophthalmology, Philadelphia, PA, USA.

SIRT1 prevents retinal ganglion cell (RGC) loss in models of optic neuropathy following pharmacologic activation or genetic overexpression. The exact mechanism of loss is not known, prior evidence suggests this is through oxidative stress to either neighboring cells or RGC specifically. We investigated the neuroprotective potential of RGC-selective SIRT1 gene therapy in the optic nerve crush (ONC) model. Read More

Compressive Optic Neuropathy with a Concurrent Mutation of Leber's Hereditary Optic Neuropathy: A Case Report.

Neuroophthalmology 2020 28;44(6):387-390. Epub 2020 Jan 28.

Department of Ophthalmology and Visual Science, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Leber's hereditary optic neuropathy (LHON) is a mitochondrial genetic disease that leads to acute or subacute, painless, bilateral loss of vision, caused by degeneration of retinal ganglion cells that most affects men in their second or third decade of life. We describe a woman with compressive optic neuropathy with a concurrent LHON-associated mitochondrial mutation. Temporal hemifield defect connected to central scotoma and concurrent abduction limitation are diagnostic clues in identifying chiasmal compression with craniopharyngioma. Read More

Intravascular Papillary Endothelial Hyperplasia as a Cause of Reversible Vision Loss.

J Craniofac Surg 2020 Nov 23. Epub 2020 Nov 23.

Department of Ophthalmology and Vision Sciences.

Intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular lesion that is formally diagnosed on histopathology. IPEH seldom presents in periocular tissues and is even less commonly seen deep within the orbit. As with cavernous hemangioma, this lesion tends to distort surrounding structures and can cause a significant mass effect in the orbit. Read More

Orbital Compartment Syndrome After High-speed Air-Gasoline Blast Injury.

Ophthalmic Plast Reconstr Surg 2020 Oct 16. Epub 2020 Oct 16.

Department of Ophthalmology, University of Texas Medical Branch, Galveston, Texas*Baylor College of Medicine, Houston, Texas, U.S.A.

Orbital compartment syndrome is an ophthalmologic emergency that requires timely surgical intervention. The authors present a rare case of orbital compartment syndrome in a 30-year-old male injured by forceful entry of air-gasoline mixture into the orbit, secondary to inadvertent firing of the piston from running mechanical diagnostics on an automobile internal combustion engine. Orbital CT revealed extensive orbital emphysema with both pre- and postseptal involvement and diffuse chemical cellulitis. Read More
