Cases of optic neuritis have been reported following the novel coronavirus disease 2019 (COVID-19), with most being unilateral and associated with demyelinating illness. We report a case of a 22-year-old woman who presented with sudden onset painless diminution of vision in both eyes six weeks following COVID-19 infection. She also had a history of left lower motor neuron (LMN) facial palsy immediately following COVID-19 disease that recovered fully on steroids. Ocular examination and ancillary and laboratory investigations pointed to bilateral atypical optic neuritis. The patient responded well to the standard optic neuritis treatment protocol. We diagnosed her as a case of left LMN facial palsy and parainfectious bilateral optic neuritis following COVID-19. Parainfectious bilateral optic neuritis and facial nerve palsy associated with COVID-19 can occur following COVID-19 disease. Ours is the first case to report the occurrence of both in a patient.
Purpose:
To assess the morphological changes in the anterior segment following laser peripheral iridotomy (LPI) in primary angle-closure disease (PACD) using Sirius Scheimpflug-Placido disk corneal topographer.
Methods:
This was a prospective observational study. A total of 52 eyes of 27 patients with PACD who underwent LPI were analyzed for iridocorneal angle (ICA), anterior chamber depth (ACD), anterior chamber volume (ACV), horizontal visible iris diameter (HVID), corneal volume (CV), central corneal thickness (CCT), and horizontal anterior chamber diameter (HACD) 1 week following LPI, using Sirius Scheimpflug-Placido disk corneal topographer. Data analysis was done using Statistical Package for the Social Sciences (SPSS) software version 19.0, and paired
t
-test was used to assess the statistical significance.
Results:
Laser peripheral iridotomy was performed in 43 eyes with primary angle-closure suspect (PACS), six eyes with primary angle closure (PAC), and three eyes with primary angle-closure glaucoma (PACG). The analysis of the data showed statistically significant changes in anterior segment parameters of ICA, ACD, and ACV. Post-laser increase in ICA from 34.13° ± 2.64° to 34.75° ± 2.84° (
P
< 0.041), mean ACD increase from 2.21 ± 0.25 to 2.35 ± 0.27 mm (
P
= 0.01), and mean ACV increase from 98.19 ± 12.13 to 104.15 ± 11.16 mm
3
(
P
= 0.001) were noted.
Conclusion:
Significantly quantifiable short-term changes in the anterior chamber parameters of ICA, ACD, and AC volume were seen after LPI in patients with PACD on Sirius Scheimpflug-Placido disc corneal topographer.
Using participatory action research (PAR), this paper explores the ethical practice of students engaged in practitioner research in a higher education context. Using narrative enquiry, the paper explores the participants' experiences of practitioner research, including ethical dilemmas that resulted from a conflict of values between the practitioner and research roles. We postulate a multi-dimensional approach to ethical practice known as 'ethical posture' emerging from our consideration of conceptions of inquiry that resulted in contrasting ethical behaviour.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
