It is controversial whether therapeutic intervention in pediatric KC should differ from adult KC. Areas covered We investigate if there is a substantial difference between pediatric and adult KC regarding disease severity and progression rate, factors important for treatment timing and prognosis. Then, feasibility of current treatment modalities is discussed based on current evidence. Expert opinion Despite several conflicting reports, pediatric KC is more severe at initial diagnosis with faster progression. Progression can be tracked in a variety of ways, including with the Belin ABCD progression system. Controlling ocular allergy and eye rubbing is the first step in treatment. The epithelium-off Dresden protocol remains the gold standard CXL approach to stop progression in pediatric KC, whereas epithelium-off accelerated CXL might be an alternative. In pediatric patients, both penetrating and lamellar keratoplasty can be challenging; however, lamellar keratoplasty seems to offer the advantage of lower graft rejection rate. Epithelium-on CXL, intracorneal ring segment implantation, excimer laser ablation + CXL protocols are not recommended in pediatric KC. Nevertheless, there remains a need for evidence-based clinical practical guidelines in pediatric KC.","PeriodicalId":39989,"journal":{"name":"Expert Review of Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45319260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recent development of hand-held spectral domain optical coherence tomography (HH-OCT) has enabled noncontact, high-resolution scanning in non-sedated newborns, infants, and young children and has provided for the first time, in vivo visualization of the retina and ON in these patient groups. Areas covered This review will address the applications, recent advances, and future potential of HH-OCT in diagnosis and monitoring of pediatric optic neuropathies. We will provide an update on the use of HH-OCT in pediatric glaucoma, congenital optic disc anomalies, optic pathway gliomas, optic atrophy, and papilledema. Expert opinion HH-OCT could offer particular utility in children with optic neuropathies, by providing noninvasive, high-resolution characterization of the optic nerve head. Optic nerve parameters, such as retinal nerve fiber layer thickness, could serve as biomarkers to assess the severity of optic nerve disease qualitatively and quantitatively. Hence, HH-OCT is emerging as a powerful imaging tool to facilitate early diagnosis, identify prognostic biomarkers, monitor disease progression, and assess response to treatment.","PeriodicalId":39989,"journal":{"name":"Expert Review of Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41538272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research design and methods This research was a cross-sectional study. Two hundred and forty eyes of 120 participants with healthy eyes underwent MPOD measurement using VISUCAM 500. Demographic and medical data were collected. Pearson’s correlation coefficient analyzed the relationship between the sum of optical densities (MPOD volume) and various factors. MPOD and its influencing factors were analyzed by stepwise multiple regression. Results The mean age of the participants was 50.7 ± 7.5 years. The mean MPOD was 0.102 ± 0.023 density units. The factors age (r = 0.261, p < 0.01), female gender (r = 0.191, p < 0.05), and consumption of lutein and zeaxanthin (L/Z) supplement (r = 0.168, p < 0.05) were positively associated with MPOD volume. In contrast, normal blood pressure (r = – 0.182, p < 0.05) was negatively associated with MPOD volume. No relationship with smoking, body mass index, lipid profile, and family history of AMD on MPOD values was observed in this study. Conclusions Age, gender and consumption of L/Z supplement were found to be significant predictors of MPOD in Thai subjects.","PeriodicalId":39989,"journal":{"name":"Expert Review of Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47356160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The utility of optical coherence tomography angiography in the management of neovascular age-related macular degeneration – current perspective","authors":"R. Schwartz, Nicola Cronbach, H. Madi, R. Reynolds, U. Chakravarthy","doi":"10.1080/17469899.2022.2084073","DOIUrl":"https://doi.org/10.1080/17469899.2022.2084073","url":null,"abstract":"Optical coherence tomography angiography (OCTA) is a relatively new imaging modality that allows visualization of the retinal and choroidal vasculature. While this has traditionally only been possible through dye-based imaging techniques (fluorescein angiography (FA) and indocyanine green angiography (ICG)), OCTA offers a fast and noninvasive alternative that is readily repeatable and can be used to image the retinal and choroidal vasculature in a single scan without the need for dye injection. Another advantage of OCTA is its ability to produce depthresolved evaluation of the reflectance data from retinal tissue, providing a three-dimensional volume of information. The retinal and choroidal capillary networks are arranged into morphologically distinct layers, from the superficial capillary plexus to the choroid. In the case of neovascular age-related macular degeneration (nAMD), this enables the clinician to determine whether a neovascular network is present, its relative position within the retina/choroid and, with the use of repeated OCTA scans over multiple visits, whether this network is changing. However, there is currently no single standard for acquisition or interpretation of OCTA data. The first commercial OCTA machine (AngioVue, Optovue, Fremont, CA) was introduced in 2014 and was based on spectral domain OCT (SD-OCT). Subsequent OCTA devices have been based on either SD-OCT or swept source OCT (SS-OCT). SD-OCT and SS-OCT are both types of Fourier domain OCT but differ in their light source, wavelength, and photodetector, which results in differences in scanning speeds and resolution of imaging at the various levels within the retina and choroid. The longer wavelength of SS-OCT (~1050 nm, vs ~840 nm for SD-OCT) and reduced sensitivity rolloff enables acquisition of high-resolution OCTA imaging particularly of neovascular networks below the retinal pigment epithelium compared with SD-OCT scanning. The quicker scanning speeds of SS-OCT also allow for a larger area to be imaged. However, different devices utilize different algorithms to process and segment the data acquired, and therefore there are differences in the images produced. Continuous advances in OCTA technology and improvements in the quality of images produced have led to increasing use of OCTA globally for clinical purposes, particularly for the diagnosis and monitoring of macular neovascularization [1]. In this article, we discuss the role of OCTA in nAMD and how it can be of use to clinicians in the diagnosis and management of nAMD.","PeriodicalId":39989,"journal":{"name":"Expert Review of Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49363650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Areas covered This manuscript will review the different techniques used to obtain small samples of uveal tumors with minimal disruption of the ocular tissues, briefly discuss clinical applications and complications of FNAB and VCCB, and ways in which to improve specimen yield and patient outcomes. Expert opinion The published literature shows a lack of uniformity in indication and surgical techniques among ocular oncologists performing FNAB and VCCB. This fact can potentially lead to discrepant results that include variable rates of success in obtaining a sufficient specimen and a wide range of complications, from intraocular hemorrhage, retinal detachment to anecdotal cases of seeding of the biopsy needle track and extraocular tumor extension. Uniform indications and surgical techniques would allow comparison among different centers and protocols to minimize and manage complications.","PeriodicalId":39989,"journal":{"name":"Expert Review of Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44037896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, reports of several side effects after immunization with COVID-19 vaccines, such as corneal graft rejection, ocular herpes simplex virus reactivation, scleritis, anterior and intermediate uveitis, multiple evanescent white dot syndrome, acute zonal occult outer retinopathy, panuveitis, multifocal choroiditis, toxoplasma retinochoroiditis, central serous retinopathy, branch/central retinal vein occlusion, paracentral acute middle maculopathy, arteritic anterior ischemic optic neuropathy, optic neuritis, third nerve palsy, superior ophthalmic vein thrombosis, and Tolosa–Hunt syndrome, are reviewed and presented. Expert opinion Our knowledge regarding vaccination-related adverse events during the COVID-19 pandemic is growing. Ocular side effects are very rare overall and can often be treatable and preventable. Vaccinations remain strongly recommended by experts due to their efficacy in decreasing the disease burden. It is of note that establishing a casual relationship between vaccines and side effects is not possible yet and the possibility of coincidence should be considered.","PeriodicalId":39989,"journal":{"name":"Expert Review of Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45765987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
