Published: September 2013

A 10-year-old child presented after accidental exposure of the left eye to a blue hair dye containing methylene blue. Mild ocular surface changes and a selective blue staining of the usually invisible corneal nerve fibre bundles were present. Corneal sensitivity was reduced. Despite copious lubrication a transient neurotrophic keratitis developed which did not resolve until corneal sensitivity became normal 2 weeks later. Association of mild chemical burns with neurotrophic keratitis is unusual but is of high clinical relevance as keratitis is a vision-threatening complication.

Ocular fungal infections are pathologies of slow progression, occurring mainly in the cornea, but can also affect the entire structure of the eyeball. The main aetiological agents are species of the genera and . Both diagnosis and treatment require speed and effectiveness.

Purpose: To compare the clinical outcomes, surgical workflow, and patient satisfaction following small incision lenticule extraction (SMILE) performed with the VisuMax 800 in one eye and the VisuMax 500 in the contralateral eye (both Carl Zeiss Meditec).

Methods: This was a prospective, single-site clinical study of patients undergoing SMILE for myopia and myopic astigmatism between February 2022 and August 2023. Each patient underwent bilateral treatment using the VisuMax 800 (VM800 group) in one eye and the VisuMax 500 (VM500 group) in the contralateral eye.

Background: Early-onset Alzheimer's disease (EOAD) associated with amyloid precursor protein (APP) duplications or presenilin (PSEN) variants increases risk of seizures. Targeting epileptiform activity with antiseizure medicine (ASM) administration to AD patients may beneficially attenuate cognitive decline (Vossel et al, JAMA Neurology 2021). However, whether mechanistically distinct ASMs differentially suppress seizures in discrete EOAD models is understudied (Lehmann et al, Neurochem Res 2021).

A New Method to Measure Ocular Surface Sensitivity: Repeatability and Reproducibility of the Liquid Jet Esthesiometer.

Eye Contact Lens

School of Optometry and Vision Science (K.E., F.S., B.T., J.C., B.G.), University of New South Wales, Sydney, Australia; and Department of Optics and Optometry and Vision Sciences (C.T.-E.), University of Valencia, Valencia, Spain.

Objectives: To assess the reliability of the liquid jet esthesiometer (LJA) for measurement of corneal sensitivity.

Methods: Two separate studies were conducted to assess intrasession repeatability (study 1) and intersession reproducibility (study 2) of corneal sensitivity measured using the LJA. Thirty participants (13 female and 17 male participants, age 23±6 years) participated in study 1 and another 30 (18 female and 12 male participants, 35±10 years) participated in study 2.

Purpose: The objective of this study was to compare the changes in postlens fluid optical density, timing and quantity of lens settling, and the clinical performance between two different mini-scleral lenses.

Methods: Seventeen eyes of 10 patients with keratoconus were fitted with a 15-mm mini-scleral lens (AirKone Scleral Lenses; Laboratoire LCS, Normandy, France), and 15 eyes of 10 patients with keratoconus were fitted with 16.5-mm mini-scleral lenses (Misa Lenses; Microlens Contactlens Technology, Arnhem, The Netherlands).
