Non-Arteritic Ischemic Optic Neuropathy Following COVID-19 Vaccination in Korea: A Case Series.

Background: To report the clinical manifestations of non-arteritic anterior ischemic optic neuropathy (NAION) cases after coronavirus disease 2019 (COVID-19) vaccination in Korea.

Methods: This multicenter retrospective study included patients diagnosed with NAION within 42 days of COVID-19 vaccination. We collected data on vaccinations, demographic features, presence of vascular risk factors, ocular findings, and visual outcomes of patients with NAION.

Clinical and Optic Disc Characteristics of Patients Showing Visual Recovery in Leber Hereditary Optic Neuropathy.

Background: The visual prognosis in Leber hereditary optic neuropathy (LHON) is generally poor. However, some individuals can have spontaneous visual recovery (VR) in one or both eyes by a mechanism that is not yet clearly understood. The purpose of this study was to determine whether certain clinical and optic disc features are associated with VR in patients with LHON.

Proposing a new scoring system in intermittent exotropia: towards a better assessment of control.

Objective: There is a clinical need for a valid and reliable assessment system to quantify the severity and measure the progression of intermittent exotropia. We have developed a new scoring system (Look And Cover, then Ten seconds of Observation Scale for Exotropia [LACTOSE]) based on the examinee's potential to regain the phoria for both distance and near fixation. The test takes only 1 minute to complete.

Comparison between aniridia with and without PAX6 mutations: clinical and molecular analysis in 14 Korean patients with aniridia.

Purpose: To describe clinical and molecular characteristics of Korean patients with aniridia and to compare the clinical phenotype between those having an identifiable PAX6 mutation and those not.

Design: Comparative case series.

Participants: A total of 14 Korean patients from 10 families with aniridia.

Visual field loss in patients with refractory partial epilepsy treated with vigabatrin: final results from an open-label, observational, multicentre study.

Background: Use of the antiepileptic drug vigabatrin is associated with an elevated risk of visual field loss.

Objective: To determine the frequency of, and risk factors for, vigabatrin-attributed visual field loss (VAVFL) in the setting of a large-scale, multinational, prospective, observational study.

Study Design: A comparative, open-label, parallel-group, multicentre study.

Vigabatrin and epilepsy: lessons learned.

Purpose: The risk factors for visual field loss attributable to vigabatrin (VAVFL) are equivocal. This multinational, prospective, observational study aimed to clarify the principal/major factors for VAVFL.

Methods: Interim analysis of three groups with refractory partial epilepsy, stratified by age (8-12 years; >12 years) and exposure to vigabatrin (VGB).

Vigabatrin and visual field defects in pediatric epilepsy patients.

We studied the prevalence, type and severity of vigabatrin (VGB)-attributed visual field defects (VFDs), and used these data to assess the associated risk factors in pediatric patients. Medical records were retrospectively reviewed for 67 pediatric patients who received VGB alone or in combination with other antiepileptic drugs, and who had undergone visual field examinations using a Humphrey visual field analyzer. Of the 67 patients, 15 had VGB-attributed VFDs: 13 had nasal arcuate type, 1 had nasal and temporal constricted type and 1 had nasal constricted type.

New concept in cavernous sinus dural arteriovenous fistula: correlation with presenting symptom and venous drainage patterns.

Background And Purpose: An extradurally located cavernous sinus dural arteriovenous fistula (CSDAVF) exhibits different clinical behavior from other dural arteriovenous fistulas (DAVFs) located between 2 dural leaves. The aim of this study is to define angiographic types of CSDAVF associated with presenting symptom (Sx) and venous drainage patterns.

Methods: CSDAVFs during a mean of 23-month follow-up period of 58 patients (17 to 73 years, male:female ratio=8:50) were retrospectively analyzed.

Wall-Eyed Monocular Internuclear Ophthalmoplegia (WEMINO) with Contraversive Ocular Tilt Reaction.

Wall-eyed monocular internuclear ophthalmoplegia (WEMINO) with contraversive ocular tilt reaction has not been previously reported. A 71-year-old woman suddenly developed blurred vision. Examination revealed left internuclear ophthalmoplegia, left exotropia, right hypotropia, and rightward head tilt.

Isolated superior rectus palsy due to contralateral midbrain infarction.

Background: Isolated superior rectus palsy due to a contralateral midbrain lesion has not been reported.

Case Description: A 71-year-old woman suddenly developed diplopia. Examination showed that she had isolated superior rectus paresis.

Nonsurgically placed nasolacrimal stents for epiphora: long-term results and factors favoring stent patency.

Purpose: To evaluate long-term effectiveness of a polyurethane stent in lacrimal system treatment.

Materials And Methods: Fluoroscopically guided placement of a polyurethane lacrimal stent was evaluated in 727 obstructed lacrimal systems in 588 patients with a mean follow-up period of 77 weeks (range, 1-277 wk), from which the technical and initial success rates and long-term patency were calculated. The impact of factors affecting long-term patency, including symptom duration, previous probing, presence of pus or eye discharge, lesion multiplicity, and site of obstruction were evaluated.
