Efficacy of enhanced monofocal intraocular lens in combined phacovitrectomy for patients with photoreceptor-preserving epiretinal membrane.

The aim of this study is to evaluate the visual outcomes and quality of an enhanced monofocal intraocular lens (IOL), compared to a conventional monofocal IOL in patients with epiretinal membrane (ERM). This retrospective comparative study reviewed medical records of 110 eyes of 110 patients with photoreceptor-preserving ERM (55 patients in each group) who underwent phacovitrectomy and received either a conventional monofocal IOL (Tecnis PCB00) or an enhanced monofocal IOL (Tecnis Eyhance ICB00) from March 2021 to October 2021. Baseline examination included corrected (CDVA) and uncorrected (UDVA) distance visual acuity, and measurement of pupil size.

Atezolizumab- and bevacizumab -induced encephalitis in a patient with advanced hepatocellular carcinoma: a case report and literature review.

Treatment with atezolizumab and bevacizumab is the first-line therapy for unresectable hepatocellular carcinoma. Although immune checkpoint inhibitors are novel and effective treatments, they can induce immune-related adverse events. However, neurological immune-related adverse events have rarely been reported.

Topographic analysis of retinal and choroidal vascular displacements after macular hole surgery.

It has been reported that the retinal vessel and macular region of the retina are displaced after macular hole (MH) surgery. However, there is no detailed information for correlations between retinal and choroidal displacements. We obtained optical coherence tomography angiography (OCTA) and en-face optical coherence tomography (OCT) images from 24 eyes to measure the retinal and choroidal vascular displacement before and after surgery.

Short-Term Real-World Outcomes of Intensive Aflibercept Injection for Refractory Neovascular Age-Related Macular Degeneration.

The aim of this study is to report short-term outcomes after the shortening of the treatment interval to 4 weeks with a treat-and-extend (TAE) regimen (Si4w) of aflibercept in patients with refractory neovascular age-related macular degeneration (nAMD). This retrospective study included 34 patients given aflibercept with a TAE regimen of a minimum of a 4-week interval when they had a limited response to bimonthly aflibercept. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) were compared before and after Si4w.

Methods: Participants with nAMD were randomised 1:1 to receive SB15 (N=224 participants) or AFL (N=225).

Predictors of treatment outcomes following treat-and-extend regimen with aflibercept for branch retinal vein occlusion: post-hoc analysis of the PLATON trial.

We investigated predictors of visual outcomes and injection interval in macular edema (ME) secondary to branch retinal vein occlusion (BRVO) treated with a treat-and-extend (TAE) regimen. All 48 patients in a multicenter study were followed for 52 weeks and received three monthly intravitreal aflibercept injections before the TAE regimen, with treatment intervals adjusted by 4 weeks, up to a maximum of 16 weeks. Various laboratory biomarkers and optical coherence tomography parameters were evaluated.

Synthesis of chiral malonates by α-alkylation of 2,2-diphenylethyl -butyl malonates via enantioselective phase-transfer catalysis.

An efficient synthetic approach for chiral malonates was established via enantioselective phase transfer catalysis. The α-alkylation of 2,2-diphenylethyl tert-butyl α-methylmalonates with (S,S)-3,4,5-trifluorophenyl-NAS bromide as a phase-transfer catalyst under phase-transfer catalytic conditions successfully produced corresponding α-methyl-α-alkylmalonates; these compounds are versatile chiral building blocks containing a quaternary carbon center in high chemical yields (up to 99%) with excellent enantioselectivities (up to 98% ee). α,α-Dialkylmalonates were selectively hydrolyzed to the corresponding chiral malonic monoacids under basic (KOH/MeOH) and acidic conditions (TFA/CHCl), showing the practicality of the method.

Clinical implications of choroidal vascular brightness using ultra-widefield indocyanine green angiography in polypoidal choroidal vasculopathy.

Polypoidal choroidal vasculopathy (PCV) is characterized by choroidal vascular abnormalities including polypoidal lesion and branching vascular networks. Not only choroidal structural changes, but also choroidal hyperpermeability and congestion are also thought to be involved in pathogenesis of PCV. We investigated choroidal vascular brightness intensity (CVB) using ultra-widefield indocyanine green angiography (UWF-ICGA) images and analyzed its association with clinical features in patients with PCV.

Neurologic Dysfunction Assessment in Parkinson Disease Based on Fundus Photographs Using Deep Learning.

Importance: Until now, other than complex neurologic tests, there have been no readily accessible and reliable indicators of neurologic dysfunction among patients with Parkinson disease (PD). This study was conducted to determine the role of fundus photography as a noninvasive and readily available tool for assessing neurologic dysfunction among patients with PD using deep learning methods.

Objective: To develop an algorithm that can predict Hoehn and Yahr (H-Y) scale and Unified Parkinson's Disease Rating Scale part III (UPDRS-III) score using fundus photography among patients with PD.

Aqueous microRNA profiling in age-related macular degeneration and polypoidal choroidal vasculopathy by next-generation sequencing.

Although many studies demonstrated the differences of clinical features, natural course, and response to treatment between typical age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV), differential microRNAs (miRNAs) expression in the aqueous humor (AH) between them has not been reported yet. We investigated the roles of miRNAs in the AH of patients with typical AMD and PCV using next-generation sequencing (NGS) and quantitative PCR (qPCR). Target genes and predicted pathways of miRNAs were investigated via pathway enrichment analysis using the Kyoto Encyclopedia of Genes and Genomes database.

MULTIMODAL IMAGING FEATURES AND TREATMENT RESPONSES OF CHOROIDAL NEOVASCULARIZATION SECONDARY TO CENTRAL SEROUS CHORIORETINOPATHY.

Purpose: To investigate features of central serous chorioretinopathy with choroidal neovascularization (CNV) on multimodal imaging and analyze their association with treatment response.

Methods: A total of 37 patients with chronic central serous chorioretinopathy complicated by CNV were divided into bevacizumab and photodynamic therapy groups, and each group was subdivided into responders and nonresponders according to subretinal fluid status at 3 months. We assessed multimodal imaging parameters (subfoveal choroidal thickness; vortex vein engorgement; choroidal vascular hyperpermeability; and CNV morphologic pattern, area, and vessel density) and analyzed their association with treatment responses.

Comparison of treatment methods for submacular hemorrhage in neovascular age-related macular degeneration: conservative versus active surgical strategy.

The optimal treatment of submacular hemorrhage (SMH) following neovascular age-related macular degeneration (nAMD) is controversial. This study aimed to compare visual outcomes of conservative versus active surgical treatment. Two hundred thirty-six eyes of 236 patients with SMH (≥ 1 disc diameter) were stratified into four groups: observation (n = 21); anti-vascular endothelial growth factor (VEGF) monotherapy (n = 161); non-surgical gas tamponade (n = 31); and subretinal surgery (n = 23).
