Myelin oligodendrocyte glycoprotein (MOG) associated optic neuritis in a patient with idiopathic intracranial hypertension (IIH) and compressive optic neuropathy case report.

BACKGROUND: Myelin oligodendrocyte glycoprotein-associated disease (MOGAD) has a wide phenotypic expression and should be considered in a differential diagnosis of patients with optic disc edema and increased intracranial pressure because MOGAD can mimic IIH and compressive optic neuropathy. CASE PRESENTATION: A 53-year-old woman with a history of presumed idiopathic intracranial hypertension ("IIH") presented with new headache and visual loss. She had a BMI of 35.44 kg/m2 and a past medical history significant for depression, hepatitis C, hyperlipidemia, and uterine cancer post-hysterectomy. She had undergone multiple lumboperitoneal shunts for presumed IIH and had a prior pituitary adenoma resection. Her visual acuity was no light perception OD and counting fingers OS. After neuro-ophthalmic consultation, a repeat cranial MRI showed symmetric thin peripheral optic nerve sheath enhancement of the intra-orbital optic nerves OU. Serum MOG antibody was positive at 1:100 and she was treated with intravenous steroids followed by plasma exchange and rituximab. CONCLUSIONS: This case highlights the importance of considering MOGAD in the differential diagnosis of optic neuropathy. Although likely multifactorial, we believe that the lack of improvement in our case from presumed IIH and despite adequate neurosurgical decompression of a pituitary adenoma with compression of the optic apparatus reflected underlying unrecognized MOGAD. Clinicians should consider repeat imaging of the orbit (in addition to the head) in cases of atypical IIH or compressive optic neuropathy especially when the clinical course or response to therapy is poor or progressive.

National Football League Game Officials Self-Rating of Knowledge in Neuro-Ophthalmic Principles and Practice: A Pilot Program to Improve Precision and Accuracy of Game Official Calls.

BACKGROUND: To determine whether a neuro-ophthalmic curriculum would improve National Football League (NFL) game officials' self-rated knowledge and interest in neuro-ophthalmic principles to improve precision and accuracy of NFL play-calling. METHODS: The formalized and structured neuro-ophthalmic principles (NOP) curriculum was introduced to 121 NFL game officials, 17 replay officials, and 4 officiating staff who attended the NFL Official Training Camp in Irving, Texas, on September 8 and 9, 2023. Before and after the lecture and videos were introduced, participants completed an optional hard-copy feedback form pertaining to self-reported NOP knowledge, likelihood of using said terms, and interest in future content of NOP applicable NFL officiating. Paired 2-tailed t tests were used for statistical analysis to directly compare the self-reported knowledge before and after the neuro-ophthalmic curriculum introduction. RESULTS: One hundred forty-two participants completed the prelecture and postlecture feedback forms self-reported knowledge after the NOP curriculum was given to the NFL officiating staff. All (142/142) participants completed a survey. There was a statistically significant improvement in the mean ratings of the prelecture vs. postlecture understanding of the specific neuro-ophthalmic terms pertinent to NFL game officials (2.6 [95% CI, 2.3-3.0] vs. 7.9 [95% CI, 7.6-8.2], P < 0.001) and 2.7 [95% CI, 2.3-3.0] vs. 7.7 [95% CI, 7.4-8.0]), respectively. There was a statistically significant greater likelihood of using said terms prelecture vs. postlecture (2.9 [95% CI, 2.4-3.4] vs. 7.5 [95% CI, 7.2-7.9], P < 0.001). CONCLUSIONS: This study found a statistically significant improvement in neuro-ophthalmic knowledge and a greater likelihood of using NOP terms following the NOP curriculum. NFL game officials, replay officials, and staff are interested in expanding their knowledge in the vision science of neuro-ophthalmic concepts and applications involved in play-calling. We hope that our pilot data will lead to a model of education that will improve the precision and accuracy of NFL play-calls by officials on game days.

Neuro-ophthalmic manifestations of Ehlers-Danlos syndrome.

PURPOSE OF REVIEW: To review the neuro-ophthalmic manifestations of Ehlers-Danlos syndrome (EDS). RECENT FINDINGS: Ehlers-Danlos syndrome (EDS) is a rare genetic disorder with an estimated prevalence of 1 in 5000 individuals, but its true prevalence may be underestimated because of variable clinical presentations and limited awareness among healthcare professionals. The neuro-ophthalmic features of EDS may be difficult to recognize in context but new molecular genetic testing is now available for identification of specific subtypes of EDS. SUMMARY: Ophthalmic manifestations of EDS include loss of vision and double vision (strabismus), high myopia, retinal detachment, and blue sclera. The vascular subtype of EDS can present as a carotid-cavernous fistula, intracranial aneurysm, or arterial dissection.

Rhino-orbital mucormycosis.

PURPOSE OF REVIEW: The current article will update and review the clinical and radiological manifestations and management of rhino-orbital mucormycosis (ROM). RECENT FINDINGS: There has been an increase in cases of ROM worldwide, especially in India. Immunosuppression (especially diabetes mellitus) is a known predisposing risk factor for ROM. Delayed diagnosis and treatment of ROM can be vision or life-threatening. This article reviews the clinical and radiologic features, treatment, and prognosis of ROM with special emphasis on new and emerging therapies. SUMMARY: ROM is an angioinvasive fungal infection that affects the sinuses and orbits and may present to ophthalmologists. Clinicians should have a high index of suspicion for ROM, especially in patients with poorly controlled diabetes mellitus or other immunosuppression. Corticosteroid treatment (including the recent COVID-19 pandemic) may be a predisposing risk factor for ROM.
