Purpose: The aim of the study was to assess the quality of videos on YouTube as educational resources about refractive surgery. Methods: This is a retrospective, cross-sectional, register-based study. A search of YouTube was performed for the term “refractive surgery” without any changes to the Web site's standard search preferences. The first 160 videos were recorded. Additional videos from the search engine were also searched for the other common terms “LASIK,” “PRK,” and “laser eye surgery.” The first 50 videos for each additional term were evaluated. A total of 310 videos were evaluated regarding DISCERN score (min–max: 16–75), Journal of the American Medical Association score (min–max: 0–4), and Global Quality score (min–max: 0–5). Results: Once 135 videos that did not meet the inclusion criteria were excluded from the sample, the remaining 175 videos were analyzed. The mean DISCERN, Journal of the American Medical Association, and Global Quality scores were 33.25 ± 15.34 (poor quality), 0.74 ± 0.82 (lowest quality), and 1.74 ± 0.81 (poor quality), respectively. Of the 175 videos, 77 (42%) had been uploaded by physicians, 67 (38.2%) by health channels, 16 (9.1%) by patients, and another 15 (8.5%) by medical organizations. Conclusions: Although some of the analyzed online videos contain beneficial information, YouTube videos do not generally seem to be useful as educational resources for patients about refractive surgery. Nevertheless, health care professionals should continue to assess the reliability and usefulness of medical information provided by online resources from the viewpoint of patients.
Orbital apex syndrome is a rare manifestation of Herpes Zoster Ophthalmicus. Herein we report on a case of orbital apex syndrome secondary to Herpes Zoster Ophthalmicus. A 75 year-old male complained of vision loss, conjunctival hyperemia and proptosis on the left eye, was referred to our clinic. Visual acuity was 5/10 Snellen lines and he had conjunctival hyperemia, chemosis, minimal nuclear cataract and proptosis on the left eye. A diagnosis of orbital pseudotumor was demonstrated firstly. The patient received oral and topical corticosteroids, antiinflammatory and antibiotic agents. On day 2, vesiculopustular lesions were observed, Herpes Zoster Ophthalmicus was diagnosed and corticosteroid treatment stopped, oral acyclovir treatment initiated. Two days later, total ophthalmoplegia, ptosis and significant visual loss were observed on the left. The diagnosis of orbital apex syndrome was considered and the patient commenced on an intravenous acyclovir treatment. After the improvement of acute symptoms, a tapering dose of oral cortisone treatment initiated to accelarate the recovery of ophthalmoplegia. At 5-month follow-up, ptosis and ocular motility showed improvement. VA did not significantly improve because of cataract and choroidal detachment on the left. We conclude that ophthalmoplegia secondary to Herpes Zoster Ophthalmicus responds favourably to intravenous acyclovir and steroids.
Purpose: To investigate monocyte to high-density lipoprotein (HDL) ratio (MHR) and neutrophil-to-lymphocyte ratio (NLR) as indicators of systemic inflammation in acute central serous chorioretinopathy (CSC). Methods: The HDL levels, hematological profiles, erythrocyte sedimentation rates (ESR), and C-reactive protein (CRP) levels of 38 patients with acute CSC (Group I) and 38 controls without CSC (Group II) were measured. Results: MHRs were significantly higher in Group I (13.30 ± 2.95) than in Group II (11.52 ± 2.42, P = 0.005), whereas NLRs, CRP values, and ESR values did not significantly differ between the groups ( P = 0.726, P = 0.219, and P = 0.441, respectively). Multivariate analysis revealed that the MHR was an independent predictor of acute CSC (OR = 1.266, 95% CI = 1.054-1.521, P = 0.012). Conclusion: Indicating an association between increased MHRs and acute CSC, the MHR might represent simple, inexpensive, reliable biomarkers of inflammation in acute CSC.
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.
