Trastuzumab-Induced Early Corneal Melt in HER2-Positive Breast Cancer: A Case Report and Review.

BACKGROUND Trastuzumab (Herceptin) is a recombinant DNA-derived humanized monoclonal antibody that the US Food and Drug Administration (FDA) approved in 1998 for metastatic human epidermal growth factor receptor 2 (HER2)-positive breast cancer therapy. It selectively binds to the extracellular domain of HER2 and mediates an antibody-dependent cellular toxicity in various tissues. Trastuzumab use alone does not typically cause aggressive ocular complications.

Outcomes of Micropulse Laser Trabeculoplasty Compared to Selective Laser Trabeculoplasty: A Systematic Review and Meta-Analysis.

Purpose: To perform a meta-analysis and systematic review to compare the efficacy and complications of micropulse laser trabeculoplasty (MLT) and selective laser trabeculoplasty (SLT) in adult patients with open-angle glaucoma (OAG) and ocular hypertension (OHT).

Methods: We performed a systematic review utilizing PubMed, Embase, and Scopus, on April 8, 2024. Meta-analyses were performed for the mean change in intraocular pressure (IOP) at one-month, six-month, and one-year follow-up visits, rate of IOP spikes (>5 mmHg increase from the pre-procedure baseline IOP), rate of treatment failure (<20% or <3 mmHg reduction in IOP or requiring additional medications or procedures), and mean change in number of medications.

Case report: Pemigatinib-induced retinopathy: a serial examination of subretinal fluid secondary to an FGFR inhibitor.

Background: Modern chemotherapeutic agents continue to evolve as modern monoclonal antibody treatments are designed to directly target proteins, enzymes, and focal loci. A particular class of these medications, fibroblast growth factor (FGFR) inhibitors, specifically pemigatinib (Pemazyre; Incyte), has been approved by the US Food and Drug Administration since April 2020 for the treatment of advanced or metastatic cholangiocarcinoma. As it is a relatively new medication, its side-effect profile is manifesting in active clinical practice.

180- Versus 360-Degree Selective Laser Trabeculoplasty in Open Angle Glaucoma and Ocular Hypertension: A Systematic Review and Meta-Analysis.

Prcis: This systematic review and meta-analysis found that 360-degree selective laser trabeculoplasty (SLT) is significantly more effective than 180-degree SLT at reducing intraocular pressure at 1-month and 1-year follow-ups without increased serious adverse event risk.

Purpose: To determine the efficacy of 180- versus 360-degree selective laser trabeculoplasty (SLT) in adults with open angle glaucoma (OAG) and ocular hypertension (OHT).

Methods: A systematic review was performed using PubMed, Embase, and Scopus databases, from 1995 to December 30, 2023, for studies comparing 180 and 360-degree SLT in adults with OAG and OHT (PROSPERO ID: CRD42024497832).

Posterior Pole Asymmetry Analysis as a Diagnostic Tool in Glaucoma Suspects: An Electrophysiological Approach.

Purpose: Spectral domain optical coherence tomography (SD-OCT) with posterior pole asymmetry analysis (PPAA) provides a mapping of posterior pole retinal thickness with asymmetry analysis between hemispheres of each eye. We investigated whether these structural abnormalities were correlated with functional retinal ganglion cell (RGC) loss, quantified by steady state pattern electroretinogram (ssPERG), in glaucoma suspects (GS).

Methods: Twenty GS (34 eyes) were enrolled in a prospective study at the Manhattan Eye, Ear, and Throat Hospital.

Extensive Cerebral Venous Sinus Thrombosis Due to Medroxyprogesterone Acetate.

This retrospective patient report describes a unique case of cerebral venous sinus thrombosis arising from hormonal contraceptive use, and the management of said thrombosis and its secondary ophthalmic manifestations. The patient initially presented with significant visual decline, headaches, florid disc oedema, and vessel tortuosity, due to extensive sinus thromboses that were causing increased intracranial pressure. It was determined that the root cause of the thrombosis was the use of injectable medroxyprogesterone acetate, leading to a hypercoagulable state.

Bilateral Proptosis in a Case of Recurring Multiple Myeloma: Uncommon Orbital Presentation of Plasmacytoma.

Multiple myeloma is a malignant plasma cell dyscrasia that may invade the orbits in extramedullary presentations. Common manifestations of orbital involvement include unilateral proptosis, injection, chemosis, diplopia, and occasionally pain. Additionally, the soft-tissue tumors associated with multiple myeloma typically cause bony destruction of adjacent structures.

Intravitreal Ziv-Aflibercept: A Comprehensive Review.

: Age-related macular degeneration is the leading cause of blindness in adults over the age of 50 in the United States of America. Neovascular age-related macular degeneration (nAMD) is sight-threatening, but can be treated by three currently utilized, intravitreally administered drugs: aflibercept, bevacizumab, and ranibizumab. Ziv-aflibercept is an analogue of aflibercept, containing the same active molecule in a different buffer solution, and its recent availability has prompted numerous pre-clinical and clinical trials addressing its viability for intraocular use, summarized herein.
