PURPOSE: Current practice for diagnostic biopsy of lacrimal gland lesions entails an orbitotomy procedure via an upper eyelid crease or lateral canthotomy skin incision. We describe a novel surgical technique to address these lesions via the lateral conjunctival fornix. METHODS: Retrospective case series of all patients who underwent a lateral fornix orbitotomy procedure for incisional or excisional diagnostic biopsy of lacrimal gland lesions. The procedure involves a conjunctival incision in the lateral fornix remote from the openings of the lacrimal ductules, and an intraperiosteal surgical corridor to access the lacrimal gland...

PURPOSE: This study aimed to compare the treatment outcomes of patients with neovascular age-related macular degeneration (nAMD) who initially received faricimab or aflibercept treatment using propensity score matching (PSM) to align patient backgrounds. METHODS: Patients with treatment-naïve nAMD who received either faricimab or aflibercept for three consecutive monthly injections as the loading phase were enrolled in this study. In the 1:1 PSM, sex, age, best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), and AMD subtypes in the pre-treatment state were selected as covariates...

BACKGROUND: The purpose of this study is to assess the variations in anterior chamber depth (ACD), axial length (AXL), and intraocular pressure (IOP) in both phakic and pseudophakic eyes undergoing preoperative intravenous mannitol infusion. The study was conducted at the Ophthalmology Department of IRCSS Humanitas in Milan, Italy. This is a prospective and non-randomized study. METHODS: 40 patients with phakic eyes and 40 patients with pseudophakic eyes scheduled for cataract surgery in their fellow eye were included...

PURPOSE: To investigate, map, and synthesize evidence regarding the correlation between changes in binocular vision and fine motor skills among children. METHODS: We conducted a scoping review of existing evidence, following the guidelines and checklist outlined in "Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Scoping Reviews" (PRISMAScR). RESULTS: Sixteen papers were systematically included in our scoping review. A predominant focus was placed on assessing the impact of strabismus on motor skills...

Diabetic macular edema (DME) is a serious vision-threatening complication that can arise at any stage of diabetic retinopathy. Primary treatment involves anti-vascular endothelial growth factor (VEGF) agents, which are highly effective but associated with challenges, such as the need for frequent injections, relapses, and resistance to therapy. Therefore, there has been a growing interest in developing new treatments that offer similar or superior outcomes in DME. This review article explores emerging treatments, including WNT agonists, gene therapy, protein inhibitors, and, most importantly, the first-ever non-invasive and oral drugs...

PURPOSE: Patients with unilateral treatment-naïve exudative neovascular age-related macular degeneration (nAMD) were examined for the presence of nonexudative macular neovascularization (neMNV) in their fellow eye using a multimodal imaging approach. This is intended to determine the sensitivity of individual imaging methods, namely, indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCTA). METHODS: In this retrospective cross-sectional study, ICGA images of the nonexudative eye were analyzed for the presence of plaques...

BACKGROUND: To describe the refractive outcomes of eyes with high regular corneal astigmatism undergoing age-related cataract surgery. METHODS: Astigmatic patients who underwent cataract surgery with implantation of high-power XY1AT HOYA® toric lenses (IOLs) (≥ T5) between March 2020 and June 2022 were included. Patients were divided into 2 groups based on the type of Total Corneal Astigmatism (TCA) used for the toric IOL calculation: group 1 = TCATK- 700 (TCA measured by the Iol Master 700® ) and group 2 = TCAAK- 700 (TCA estimated from the anterior keratometry of the Iol Master 700® and using the Abulafia-Koch regression)...

PURPOSE: The aim of this study is to compare optical quality results obtained in laboratory analysis (in vitro) versus clinical data (in vivo). METHODS: The optical quality of ISOPure intraocular lens was assessed both in vitro and in vivo using the modulation transfer function (MTF) for 3.0 and 4.5 mm pupil diameters. In vitro measurements were obtained using deflectometer NIMO TRF1504, while in vivo measurements were taken with OPD-Scan III in a set of patients implanted with this lens...

BACKGROUND: To evaluate the repeatability and agreement of two different ocular biometers and Scheimpflug devices in keratoconus eyes. METHODS: This prospective, comparative trial took place at the University hospital, Goethe University, Frankfurt am Main, Germany. We included eyes with keratoconus, one eye per patient, randomly selected. Measurements were taken with Galilei G6 (Ziemer, Switzerland) and Pentacam AXL (Oculus, Germany), three consecutive measurements each...

PURPOSE: To assess the sensitivity and specificity of the "triple layer sign" (TLS) (retinal pigment epithelium (RPE), neovascular tissue, and Bruch's membrane) on structural optical coherence tomography (OCT) images for the diagnosis of treatment-naïve non-exudative type-1 macular neovascularization (NE-MNV) in age-related macular degeneration (AMD). DESIGN: Cross-sectional study. METHODS: Two masked retinal experts evaluated the presence of the TLS in eyes with NE-MNV and controls with an RPE elevation without exudation due to other causes than NE-MNV in AMD [e...

PURPOSE: In the current investigation, the effects of the mTOR inhibitors, Rapa and Torin1 on the TGF-β2-induced conjunctival fibrogenesis were studied. STUDY DESIGN: Experimental research. METHODS: 2D and 3D cultures of HconF were subjected to the following analyses; (1) planar proliferation evaluated by TEER (2D), (2) Seahorse metabolic analyses (2D), (3) subepithelial proliferation evaluated by the 3D spheroids' size and hardness, and (4) the mRNA expression of ECM proteins and their regulators (2D and 3D)...

PURPOSE: To investigate the relationship between accommodation and intraocular pressure (IOP). METHODS: Systematic literature search and meta-analysis following PRISMA guidelines was conducted on studies analyzing the relationship between accommodation and intraocular pressure. After removal of duplicates, title and abstract screening, full-text analysis was performed to select relevant articles and meta-analysis was then conducted as well. RESULTS: Of the 1357 records identified, 17 met the selection criteria and were included...

BACKGROUND: We aimed to investigate the effect of retinal vein occlusion (RVO) on the posterior segment structures of the eye and its changes with intravitreal anti-Vascular Endothelial Growth Factor (VEGF) treatment. METHODS: This prospective longitudinal study included 29 eyes of 29 patients with RVO (17 males and 12 females) followed for 6 months. The best corrected visual acuity (BCVA), macula, choroid ticknesses and choroidal vascularity index (CVI) obtained by spectral-domain optical coherence tomography were recorded at baseline and the first, third, and sixth months after the first injection...

PURPOSE: To investigate the correlation between the autonomic nervous system and choroidal vascularity in patients with central serous chorioretinopathy (CSC), using heart rate variability (HRV) analysis, optical coherence tomography (OCT) and OCT angiography (OCTA). METHODS: We retrospectively analyzed data of 25 patients with unilateral CSC (50 eyes, including the unaffected fellow eyes) and 25 healthy controls. The assessment involved a 5-minute HRV analysis encompassing both frequency and time domains, especially low frequency (LF), high frequency (HF), and LF/HF ratio...
