[Thésaurus Mesh]Présentations de casRésumé : SIGNIFICANCE
Leber's hereditary optic neuropathy (LHON) is often associated with onset in the young, adult male demographic. This case report serves as a reminder that it can affect both sexes with onset into middle age.
PURPOSE
Leber's hereditary optic neuropathy is a maternally inherited mitochondrial disorder that typically affects men during young adulthood. It presents with a rapid, yet painless loss of vision, with the fellow eye often affected within a few months. The optic neuropathy causes a dense central scotoma with visual acuities reduced to less than 20/400.
CASE REPORT
A 60-year-old White woman presented with reports of decreased vision in both eyes for the previous 2 months. She had been followed up for the previous 5 years for glaucoma suspect monitoring, with full fields and normal optical coherence tomography scans. Entering visual acuity was finger counting at 1 m in the right eye and 20/100 in the left eye. Pupil testing revealed a grade 1 relative afferent pupillary defect in the right eye. Dilated fundus examination revealed stable moderate optic nerve cupping and intact neuroretinal rim tissue. Humphrey 24-2 Swedish Interactive Thresholding Algorithm standard visual field testing showed a significant superior altitudinal defect and inferior paracentral defect in the right eye and a partial superior arcuate in the left eye. The result of the MRI with contrast of the head and orbits was normal. A history of alcoholism was elicited, and LHON testing revealed positive 11778 mutation at homoplasmy.
CONCLUSIONS
Although still uncommon, presentation of LHON in a middle-aged woman is possible and should be considered a viable differential diagnosis when individuals present with painless vision loss and central/centrocecal scotomas.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:pression intraoculaireMots-clés : teaching glaucoma disease management optometry intraocular pressure Résumé : SIGNIFICANCE: Peak IOP and IOP fluctuations have been implicated as risk factors for glaucoma progression. Peak 24-hour IOP can be significantly higher than in-office measurements. Icare HOME could be a useful adjunct in glaucoma management if positively appraised by individuals familiar with eye care. PURPOSE: The purpose of this study was to measure the time needed for a nonclinical convenience sample of optometry students and optometrists to self-measure IOP using Icare HOME and to determine their perceptions of rebound self-tonometry. METHODS: A total of 234 subjects were enrolled, with 226 (97%) having a complete data set. Self-measurement was performed on the study eye using Icare HOME while seated and without contact lenses. Examiners self-measured IOP while subjects observed; examiners then measured subjects' IOP. Subjects then completed self-measurement while timed. Only one attempt was allowed. Time and study eye were recorded, and subjects completed a short survey. Descriptive statistics were conducted. RESULTS: Mean ± standard deviation age was 34.6 ± 13.3 years (58.3% female, 52.3% contact lens wearers). Test time ranged from 3 to 366 seconds, with 38% able to self-measure in 10 seconds or less, 74% in 60 seconds or less, and 92.8% in 120 seconds or less; 5.8% were unable to self-measure IOP. There was no significant correlation between test time and age (r = −0.03, P = .67). The device was reported to be easy or very easy to use by 69.7% of subjects and comfortable or very comfortable by 90.4% of subjects. After the study, 89.1% of subjects perceived that rebound self-tonometry has a role in the management of patients with glaucoma and suspicion of glaucoma. CONCLUSIONS: The majority of neophyte subjects perceived self-measurement of IOP as having a role in the management of glaucoma and suspicion of glaucoma. They rated Icare HOME as comfortable and easy to use and were able to self-measure IOP on the first attempt.

This study highlights the value that the public places on obtaining trusted and accessible health-related information and their preference for obtaining it from their health care practitioners. Previous research has not been specific to Canadians or vision. Findings can be used to increase eye health literacy and eye care utilization.
PURPOSE
Canadians underuse eye care and underestimate the occurrence of asymptomatic eye disease. This study explored eye information-seeking practices and preferences among a group of Canadians.
METHODS
Using snowball sampling, a 28-item online survey collected respondent perceptions about their eye and health information-seeking practices and preferences. Questions examined electronic device access, information source use, and demographics. Two open-ended questions examined information-seeking practices and preferences. Respondents were at least 18 years old and living in Canada. Individuals working in eye care were excluded. Response frequencies and z scores were computed. Written comments were assessed using content analysis.
RESULTS
Respondents searched for less eye than health information (z scores ≥ 2.25, P < .05). For eye and health information, primary care providers were the used and preferred source, and reliance on Internet searches was greater than desired. Trust and access drove information-seeking practices. Respondent comments suggested that a hierarchy of trust operates across My Health Team, My Network, and My External Sources, with a persistent threat posed by Discredited Sources. Access to information sources seemed mediated by enablers (Convenience and Accessible Features) and barriers (Unreachable Health Team and Absent Systems). Eye information was seen as more specialized and harder to find. There was a high regard for health care practitioners who provide their patients with curated trusted information.
CONCLUSIONS
These Canadians value trusted and accessible health-related information. They prefer eye and health information from their health care practitioners and value when their health team provides online curated information, particularly regarding eyes.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

We propose an alternative method for eye drop self-administration. Similar IOP reductions were found with this method compared with clinician instillation. The alternative method of self-administration potentially benefits patients who have trouble successfully instilling drops.
PURPOSE
The purpose of this study was to validate the efficacy of an alternative method of drop instillation.
METHODS
This study is a randomized controlled crossover clinical trial. Thirty participants were recruited. A drop of 0.5% timolol maleate was instilled into subject's eye on two separate visits. On one visit, eye drop instillation was by a trained clinician, and on the other, self-instillation using an alternative method was used. The order was randomly chosen. Intraocular pressure was measured before drop instillation and 2 hours after drop instillation. The investigator was masked during measurement, and an observer recorded the IOP measurements.
RESULTS
Mean ± SD IOP measurement before 0.5% timolol maleate instillation measured 13.89 ± 2.29 mmHg. An average reduction 3.75 ± 2.36 mmHg was found with clinician administration, and an average reduction of 3.32 ± 2.31 mmHg was recorded with the new method. No significance was found in IOP reduction between two groups P < .45. Percent reduction was 25.17 ± 16.21% and 24.38 ± 16.31% in clinician instillation and alternative instillation method group, respectively. No significant difference was found. This percentage reduction was similar to previously reported studies. No reported cases of eye infection or irritation were found in any case, within a 3-month follow-up period.
CONCLUSIONS
We have proposed a more reliable method for instillation that provides a larger area for instillation and lessen the risk of contamination and patient's fear for eye drops. Similar efficacy was found compared with that of having a clinician directly administer the drop. This alternative method could potentially benefit patients who require topical eye drop therapy and result in increased compliance.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
