Purpose: The purpose of this study was to report the most severe documented ocular injury caused by Ecballium elaterium , an invasive and toxic herb characterized by an explosive seed dispersal.
Methods: A 55-year-old man presented to the emergency department several hours after direct exposure to the contents of E. elaterium to his left eye. Clinical examinations, investigations, and imaging findings are reported.
Results: Medical and ocular histories were unremarkable. On presentation, the patient exhibited markedly decreased visual acuity, severe periorbital edema, conjunctival chemosis, and corneal edema. Although other signs gradually improved, corneal edema worsened despite rapid initiation of systemic and topical steroids and normal intraocular pressure. After 4 months of follow-up, the cornea cleared and visual acuity returned to normal; however, a significant decrease in endothelial cell count was observed.
Conclusions: Ecballium elaterium may cause a severe corneal chemical burn, with subsequent long-standing corneal edema and endothelial decompensation. Specular microscopy is a modality of great importance in these cases.

Diabetes Endothelial Keratoplasty Study: Methods and Impact on the Use of Corneas From Donors With Diabetes for Descemet Membrane Endothelial Keratoplasty.
Cornea
January 2025
Department of Ophthalmology and Visual Sciences, Case Western Reserve University School of Medicine, University Hospitals Eye Institute, Cleveland, OH.
Purpose: Describe aims, methods, characteristics of donors, donor corneas and recipients, and potential impact of the Diabetes Endothelial Keratoplasty Study (DEKS).
Methods: The DEKS is a randomized, clinical trial to assess graft success and endothelial cell density (ECD) 1 year after Descemet membrane endothelial keratoplasty (DMEK) using corneas from donors with versus without diabetes in a 1:2 minimization assignment. Diabetes severity in the donor is assessed by medical history, postmortem HbA1c, and donor skin advanced glycation end-products and oxidation markers.
Refractive Changes and Corneal Thickness in Healthy Mountaineers at High Altitude: The Korzhenevskoi Experience (7105 m).
Cornea
January 2025
Department of Ophthalmology, Rothschild Foundation, Paris, France; and.
Purpose: The purpose of this study was to investigate the effect of hypoxia and hypobaric conditions on refraction and central corneal thickness on healthy corneas during an ascent without oxygen supplementation above 7000 m (23 000 ft).
Methods: Twelve multinational mountaineers were included in a prospective observational cohort study during an expedition to the Korzhenevskoi Peak (7105 m). The two patients excluded from the study had a history with keratoconus or were current wearers of rigid contact lenses.
Anatomical and functional results of patients with late-stage age-related macular degeneration 6 months after smaller-incision new-generation implantable miniature telescope (SING IMT™) implantation.
Eye (Lond)
January 2025
Department of Translational Medicine, University of Ferrara, Ferrara, Italy.
Objectives: The aim of the study was to evaluate anatomical and functional outcomes of the Smaller-Incision New Generation Implantable Miniature Telescope (SING IMT™) in patients with bilateral advanced age-related macular degeneration (AMD).
Methods: This non-comparative retrospective single-surgeon interventional case series included patients with bilateral late-stage AMD who underwent cataract surgery and SING IMT™ implantation at the Sant'Anna University Hospital, University of Ferrara, Italy. The main outcome measures included corrected distance (CDVA) and near visual acuity (CNVA), endothelial cell loss (ECL), and incidence of complications.
4.5-Year Follow-up with a Novel Corneal Endothelial Prosthesis.

Ophthalmology, Amsterdam UMC, Amsterdam, Netherlands.
Background: Refractory corneal edema is the foremost reason for endothelial corneal transplantation (EK) in the world. Descemet membrane endothelial keratoplasty (DMEK) and Descemet stripping automated endothelial keratoplasty (DSAEK) offer good clinical outcomes. However, human donor tissue is limited in availability and has a complex logistical chain.

Academic Ophthalmology, School of Medicine, AU1, University of Nottingham, Nottingham, United Kingdom.
Purpose: Anterior segment optical coherence tomography (AS-OCT) is increasingly being used to complement slit-lamp biomicroscopy in the evaluation of corneal infections. Our purpose was to analyze, compare, and correlate the clinical signs elicited by these 2 methods in patients with infectious keratitis (IK).
Methods: Slit-lamp photomicrographs (diffuse and slit beam) and AS-OCT scans were obtained from 20 consecutive patients (21 eyes) with IK.
