PURPOSE: The objective of this study was to establish the presence of a causal linkage between prevalent systemic diseases and keratoconus (KC). DESIGN: Mendelian randomization (MR) analysis. METHODS: After an exhaustive screening process, genetic variants linked to various systemic diseases were identified as instrumental variables at the genome-wide significance level. Subsequently, MR analyses were conducted to elucidate their potential causal connection with KC (N = 26,742)...

PURPOSE: To assess whether the use of measured posterior corneal astigmatism (PCA) values improves the prediction accuracy of toric intraocular lens power formulas, compared to predicted PCA values, when the orientation of the steep axis of PCA is non-vertical. DESIGN: Retrospective observational cohort study METHODS: 418 eyes of 344 patients were included in the study. Prediction errors (PE) for postoperative refractive astigmatism at 4 weeks postoperatively were determined using vector analysis and compared for the following toric intraocular lens power formulas: Barrett Toric with predicted posterior corneal astigmatism (PPCA); Barrett Toric with measured posterior corneal astigmatism (MPCA); EVO Toric PPCA; EVO Toric MPCA; Holladay I with Abulafia-Koch regression...

PURPOSE: To develop deep learning (DL) algorithm to detect glaucoma progression using optical coherence tomography (OCT) images, in the absence of a reference standard. DESIGN: Retrospective cohort study. METHODS: Glaucomatous and healthy eyes with ≥5 reliable peripapillary OCT (Spectralis, Heidelberg Engineering) circle scans were included. A weakly supervised time-series learning model, called Noise Positive-Unlabeled (Noise-PU) DL was developed to classify whether sequences of OCT B-scans showed glaucoma progression...

PURPOSE: To assess the relationship between the change of optic disc vessel density (ODVD) and retinal nerve fiber layer (RNFL) thinning in primary open-angle glaucoma (POAG) patients. DESIGN: Retrospective case series. METHODS: For 105 POAG patients, ≥ 5 consecutive optical coherence tomography (OCT) and OCT angiography (OCTA) images were obtained during ≥ 2 years of follow-up. Based on enface OCTA imaging, ODVD was calculated as the ratio of pixels occupied by vessels below the internal limiting membrane within the temporal area of the optic cup, and ODVD reduction was determined when there was a statistically significant negative slope (P < 0...

PURPOSE: To evaluate the predictive accuracy of modern intraocular lens (IOL) formulas and axial length (AL) adjusted traditional IOL formulas, including Wang-Koch and Cooke-modified AL (CMAL) method, in long eyes with plate-haptic IOLs, and to compare refractive prediction error variances with C-loop IOLs. DESIGN: Retrospective consecutive case series study. METHODS: Data from 391 eyes with Zeiss 509M and 302 eyes with Alcon SN6CWS implants in highly myopic patients, following cataract surgery from January 2019 to November 2023, were collected...

PURPOSE: To review the current and future approaches to investigating the intraocular immune response in human uveitis. DESIGN: Perspective METHODS: Review of currently available methods for investigating the immune response in ocular tissues and fluids in patients with intraocular inflammation/ uveitis. The advantages and disadvantages of human studies have been compared to those of animal models of uveitis. RESULTS: Animal models, while being excellent tools for mechanistic studies, do not replicate the clinical and immunological heterogeneity of human uveitis...

PURPOSE: To compare the quality of images of gratings placed in a model eye viewed through an extended depth of focus (EDoF) intraocular lens (IOL) to that of diffractive bifocal IOL or monofocal IOL. DESIGN: Experimental laboratory investigation. METHODS: Non-diffractive wavefront shaping EDoF (CNAET0, Alcon laboratories), echelette-designed EDoF (ZXR00V, Johnson & Johnson Vision), diffractive bifocal IOL with low power addition (SV25T, Alcon Laboratories), or monofocal IOL (CNA0T0, Alcon laboratories) was placed in a fluid-filled model eye...

PURPOSE: To evaluate the visual outcomes and perioperative complications for cataract surgery in eyes with axial length (AL) > 33.0 mm. DESIGN: Prospective clinical cohort study. METHODS: One hundred and twenty-two eyes with moderate high myopia (26.0 mm ≤ AL<28.0 mm, control group), and 118 eyes with extreme high myopia (AL > 33.0 mm, EHM group) were followed up after cataract surgery (one week and one year post-op). Myopic maculopathy grading according to ATN system, best-corrected visual acuity (BCVA), and complications were compared...

PURPOSE: To ascertain whether the use of ultra-wide-field fluorescein angiography (UWFFA) at baseline visit alters the assessment of disease activity and localization, as well as the management of patients presenting to a tertiary uveitis clinic. DESIGN: Retrospective comparison of diagnostic approaches. METHODS: Baseline visits of 158 patients who presented to the Uveitis Clinic at the Byers Eye Institute at Stanford between 2017 and 2022 were evaluated by three uveitis-trained ophthalmologists (I...

PURPOSE: To assess the effect of blue-light filtering (BLF) intraocular lenses (IOLs) on the development and progression of macular atrophy (MA) in eyes with neovascular age-related macular degeneration (nAMD). DESIGN: Retrospective clinical cohort study. METHODS: nAMD patients with anti-vascular endothelial growth factor (VEGF) injections who underwent uneventful cataract surgery between 2007 and 2018 with follow-up until June 2023. Subsequent MA rates were compared between subjects who received a BLF IOL or a non-BLF IOL...

PURPOSE: Patients with non-infectious uveitis (NIU) can require treatment with systemic immunomodulatory therapy (IMT), but it is unclear whether IMT drug categories increase the risk of malignancy in NIU patients. The purpose of this study is to determine if the use of systemic IMT in patients with NIU is associated with an increased risk of malignancy. DESIGN: Clinical cohort study METHODS: Patients were identified from a U.S. administrative medical claims database including some Medicare Advantage and commercial plans, from 2000 to 2022...

PURPOSE: To assess the incidence of secondary glaucoma in children following congenital cataract surgery. DESIGN: Systematic review and meta-analysis. METHODS: The PubMed, Embase, Cochrane Library, and Web of Science databases were searched from inception through March 16, 2023. Studies reporting congenital cataract surgery and glaucoma were enrolled. The quality of the selected studies was assessed using the Newcastle Ottawa Scale, and data analysis was executed utilizing R software...
