Hyperacute optic neuritis in a patient with COVID-19 infection and vaccination: a case report.

Background: As scientific knowledge continues to grow regarding coronavirus disease 2019 (COVID-19) infection, several neuro-ophthalmological manifestations have emerged, including rare reports of optic neuritis. Optic neuritis is an inflammatory demyelinating condition of the optic nerve that typically presents as subacute, unilateral vision loss and pain on eye movement. Several cases of COVID-19 infection and COVID-19 vaccination related cases of optic neuritis have been reported.

Umbilical Cord Graft for Refractory Neurotrophic Keratopathy.

Purpose: The purpose of this study was to evaluate whether an umbilical cord tissue graft (UCG) could promote reepithelialization in refractory cases of neurotrophic keratopathy, which failed traditional treatment modalities including amniotic membrane grafts.

Methods: This retrospective case series included 3 eyes of 3 patients who underwent UCG placement for refractory stage 3 neurotrophic keratopathy. Records were reviewed to evaluate the clinical course including previous treatments, time to UCG dissolution, time to corneal epithelialization, and recurrence of epithelial defects.

Bilateral cranial nerve 6 palsy in a patient with multiple sclerosis and vitamin D-dependent rickets.

The development of multiple sclerosis (MS) is multifactorial. Elevated levels of vitamin D may lower the risk and reduce relapses by immunomodulatory mechanisms. Conversely, vitamin D-dependent rickets (VDDR), an inheritable form of rickets secondary to impairment in vitamin D synthesis or action, may increase MS risk.

Comparison between the Recommendations of Glaucoma Specialists and OCT Report Specialists for Further Ophthalmic Evaluation in a Community-Based Screening Study.

Purpose: To compare glaucoma referral patterns between glaucoma and OCT report specialists and to determine what influence, if any, a designated OCT reading could have on a glaucoma specialist's judgments.

Design: Retrospective, exploratory study.

Subjects: We included 483 eyes (243 individuals) from high-risk New York City neighborhoods screened as part of a mobile van glaucoma screening study from July 2017 to October 2017.

Real-Time Mobile Teleophthalmology for the Detection of Eye Disease in Minorities and Low Socioeconomics At-Risk Populations.

Purpose: To examine the benefits and feasibility of a mobile, real-time, community-based, teleophthalmology program for detecting eye diseases in the New York metro area.

Design: Single site, nonrandomized, cross-sectional, teleophthalmologic study.

Methods: Participants underwent a comprehensive evaluation in a Wi-Fi-equipped teleophthalmology mobile unit.

Detecting Progression in Advanced Glaucoma: Are Optical Coherence Tomography Global Metrics Viable Measures?

Significance: Optical coherence tomography (OCT) summary measures have been suggested as a way to detect progression in eyes with advanced glaucoma. Here, we show that these measures have serious flaws largely due to segmentation errors. However, inspection of the images and thickness maps can be clinically useful.

OCT Circle Scans Can Be Used to Study Many Eyes with Advanced Glaucoma.

Purpose: To examine the utility of optical coherence tomography (OCT) for studying eyes with advanced glaucoma [i.e., eyes with a 24-2 visual field (VF) mean deviation (MD) worse than -15 dB], we tested the hypothesis that if these eyes had a 10-2 total deviation (TD) map with points better than -8 dB, then the topographically corresponding regions on the circumpapillary retinal nerve fiber layer (cpRNFL) should show a preserved region.

Qualitative evaluation of neuroretinal rim and retinal nerve fibre layer on optical coherence tomography to detect glaucomatous damage.

Purpose: To understand the added value of Bruch's membrane opening-minimum rim width (BMO-MRW) measurements to conventional circumpapillary retinal nerve fibre layer (cpRNFL) thickness measurements on optical coherence tomography (OCT) imaging for discriminating between perimetric glaucoma and healthy eyes, evaluated through a qualitative evaluation.

Methods: 384 healthy eyes and 188 glaucoma eyes were evaluated, and glaucoma eyes were categorised as perimetric (n=107) based on a history of ≥3 consecutive abnormal 24-2 visual field tests or suspected glaucoma if they did not (n=81). OCT-derived BMO-MRW and cpRNFL reports were qualitatively evaluated by two experienced graders in isolation at first, and then by using both reports combined.

Structure-Function Agreement Is Better Than Commonly Thought in Eyes With Early Glaucoma.

Purpose: To assess the agreement between structural (optical coherence tomography [OCT]) and functional (visual field [VF]) glaucomatous damage with an automated method and deviation/probability maps, and to compare this method to a metric method.

Methods: Wide-field spectral-domain OCT scans, including the disc and macula, and 24-2 and 10-2 VFs were obtained from 45 healthy control (H) eyes/individuals, and 53 eyes/patients with 24-2 mean deviation (MD) better than -6 dB diagnosed as "definite glaucoma" (DG) by experts. Abnormal structure-abnormal function (aS-aF) agreement was assessed with an automated topographic (T) method based upon VF pattern deviation and OCT probability maps.
