Jan 27th, 2023 - The geographic distribution of pediatric ophthalmological care has not been reported on since 2007; understanding this distribution could shed light on potential avenues to increase access, which is a necessary first step in addressing the pediatric ophthalmological needs of underserved areas. To analyze the number and location (ie, geographic distribution) of pediatric ophthalmologists in rela...

Jan 26th, 2023 - Bicuspid aortic valve (BAV) disease is associated with increased risk of aortopathy. In addition to current intervention guidelines, BAV mediated changes in aortic 3D hemodynamics have been considered as risk stratification measures. We aimed to evaluate the association of 4D flow cardiovascular magnetic resonance (CMR) derived voxel-wise aortic reverse flow with aortic dilation and to investig...

Jan 22nd, 2023 - Ascending aorta (AAo) acute pathology still has an open-surgery indication with a high mortality rate associated to cardiopulmonary bypass and circulatory arrest. In these cases, the endovascular aortic approach could be an excellent option. The aim of the present study is to detail an optimized technique for the endovascular treatment of AAo diseases, based on thoracic endovascular aortic repa...

Jan 10th, 2023 - Background Proliferative vitreoretinopathy (PVR) is the most common cause of failure in retinal detachment surgery. [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11] It can occur in untreated eyes or occur after pneumatic retinopexy, cryotherapy, laser retinopexy, scleral buckling, or vitrectomy. [6, 9, 10] Because excessive retinopexy and operating on inflamed eyes can cause proliferative vitreoretinopathy,...

Jan 10th, 2023 - Background Proliferative vitreoretinopathy (PVR) is the most common cause of failure in retinal detachment surgery.[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11] It can occur in untreated eyes or occur after pneumatic retinopexy, cryotherapy, laser retinopexy, scleral buckling, or vitrectomy.[6, 9, 10] Because excessive retinopexy and operating on inflamed eyes can cause proliferative vitreoretinopathy, s...

Jan 6th, 2023 - Researchers have found a genetic link between the risk for COVID-19 infection and the leading cause of vision loss among people age 50 and older, age-related macular degeneration. The findings show that COVID and AMD were associated with variations in what is called the PDGFB gene, which has a role in new blood vessel formation and is linked to abnormal blood vessel changes that occur in AMD.

Dec 19th, 2022 - To review the current published literature on the utility of corneal hysteresis (CH) to assist the clinician in the diagnosis of glaucoma or in the assessment of risk for disease progression in existing glaucoma patients. Searches of the peer-reviewed literature in the PubMed database were performed through July 2022. The abstracts of 423 identified articles were examined to exclude reviews and...

Dec 4th, 2022 - The middle fossa approach is an effective option for the treatment of small (Koos grade I and II) vestibular schwannomas (VSs) when the goal is hearing preservation. The authors evaluated the rates of hearing preservation and examined the factors associated with improved hearing outcomes after the middle fossa approach for VSs. In this retrospective, single-center cohort study evaluating the cl...

Dec 1st, 2022 - Hydroxychloroquine (HCQ) is a disease-modifying, anti-rheumatic drug that regulates immune system activity and is typically prescribed to treat rheumatoid arthritis and systemic lupus erythematosus, as well as other immune conditions. Although generally well tolerated, study data have demonstrated that long-term use of HCQ may lead to irreversible and potentially vision-threatening retinal toxi...

Nov 27th, 2022 - Optic neuropathy is a near ubiquitous feature of Friedreich's ataxia (FRDA). Previous studies have examined varying aspects of the anterior and posterior visual pathways but none so far have comprehensively evaluated the heterogeneity of degeneration across different areas of the retina, changes to the macula layers and combined these with volumetric MRI studies of the visual cortex and frataxi...

Nov 27th, 2022 - To review the literature on the efficacy of surgical procedures to improve visual acuity (VA) in patients with infantile nystagmus syndrome (INS). Literature searches were last conducted in January 2022 in the PubMed database for English-language studies with no date restrictions. The combined searches yielded 354 abstracts, of which 46 were reviewed in full text. Twenty-three of these were con...

Nov 27th, 2022 - This study aimed to improve local management of paediatric otitis media using the 2022 American-Academy of Otolaryngology Head and Neck Surgery (AAO-HNS) Clinical Practice Guideline for Tympanostomy Tubes in Children. A SQUIRE 2.0 compliant quality improvement study was carried out within the outpatient department of our otolaryngology tertiary referral centre. Local outpatient management of pa...

Nov 12th, 2022 - Background/Purpose: Hydroxychloroquine (HCQ) is a medication used in most patients with systematic lupus erythematous (SLE). It is generally a safe; however, it can cause retinal toxicity and lead to blindness. A study published in JAMA in 2014 reported a prevalence of 7.5% of HCQ related eye disease (Melles and Marmor, 2014). Screening guidelines were then updated in 2016 by the American Acade...

Oct 28th, 2022 - A hybrid membrane is employed as a high-order plasmonic distributed feedback (DFB) cavity to reduce the lasing threshold of polymer lasers. The hybrid membrane consists of an anodic aluminum oxide (AAO) membrane, a 25 nm thick silver layer and a free-standing polymer membrane. The AAO membrane is fabricated by a low-cost, single chemical etching method. Then, a layer of silver with a thickness ...
