Self-reported prevalence and risk factors associated with keratoconus among the adult population of Trinidad and Tobago: a cross-sectional study.
Int Ophthalmol
January 2025
Discipline of Optometry, University of KwaZulu-Natal, Durban, South Africa.
Aim: To determine the prevalence of keratoconus and its associated risk factors within the adult population of Trinidad and Tobago.
Method: A population-based cross-sectional study was conducted among adults in Trinidad and Tobago, utilizing the Keratoconus Risk Assessment Questionnaire (KRIS) for data collection. Data were exported to the Statistical Package for Social Sciences (SPSS) version 27 for analysis.

Background: Permethrin is a pesticide used to kill insects, and once used in excess, it poses a great threat to the environment and human health, therefore, it is necessary to realize the rapid and accurate detection of permethrin. Fiber optic surface enhanced Raman scattering (SERS) probes have the advantages of small volume and can be used for remote monitoring, which have great potential for application in achieving in-situ detection of pesticide residues.
Results: Fiber taper waist (FTW) SERS probes modified by silver nanocubes-graphene oxide (Ag NCs-GO) composite structures were prepared for in situ detection of permethrin in lake water.
ECoGScope: An integrated platform for real-time Electrophysiology and fluorescence imaging.

Emotion, Cognition, & Behavior Research Group, Korea Brain Research Institute 61, Cheomdan-ro, Dong-gu, Daegu, 41062, Republic of Korea. Electronic address:
In this study, we present ECoGScope, a versatile neural interface platform designed to integrate multiple functions for advancing neural network research. ECoGScope combines an electrocorticography (ECoG) electrode array with a commercial microendoscope, enabling simultaneous recording of ECoG signals and fluorescence imaging. The electrode array, constructed from highly flexible and transparent polymers, ensures conformal contact with the brain surface, allowing unobstructed optical monitoring of neural activity alongside electrophysiological recordings.

January 2025
Department of Ophthalmology and Visual Sciences, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.
Purpose: This study aimed to report the use, efficacy, and safety of intracameral voriconazole as an adjuvant treatment for deep fungal keratitis.
Methods: This was a prospective case series of seven eyes with fungal keratitis with anterior chamber involvement or a corneal ulcer refractory to conventional topical treatment. In addition to topical treatment with 0.
Analysis and optimization of the landing zone parameters of a sclera lens model.
Arq Bras Oftalmol
January 2025
Ophthalmology and Visual Sciences Department, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.
Purpose: This study aimed to modify scleral contact lenses to achieve a desired compression standard and to evaluate the effectiveness and reliability of the adjustments.
Methods: In this nonrandomized, noncomparative, and partially masked study Scleral contact lens fittings were analyzed in 20 eyes of 12 patients (50% women, 50% men) diagnosed with keratoconus. Participants were selected based on their need for scleral contact lenses (SCLs), which was determined in complete ophthalmological examinations.
