Background: Visual impairment is a functional limitation of the eye brought on by a disorder or disease that can make it more difficult to carry out daily tasks. Visual impairment causes a wide range of public health, social, and economic issues, particularly in developing nations, where more than 90% of the world's visually impaired people reside. Although many studies conducted in Ethiopia related with the topic, there were focused on childhood visual impairments.
Objectives: To assess the prevalence and factors associated with visual impairment among older adults.
Methodology: A community-based cross-sectional study design was conducted in Arba Minch Zuria District. Systematic sampling technique was employed to select 655 adults aged 40 and above. Data were gathered through face-to-face interviews and visual acuity measurements, and SPSS version 25 was used for analysis. Bivariate and multivariate logistic regression analyses were performed to identify factors associated with visual impairment.
Results: The overall prevalence of visual impairment was found to be 36.95% (95% CI=33.2-40.8%). Factors associated with a higher odds of visual impairment included aged 51-60 years (AOR=2.37,95%CI=1.29-4.44), aged 61 and above (AOR=8.9, 95%CI=4.86-16.3), low wealth index ((AOR=1.81, 95%CI: 1.14-3.2), divorced and widowed (AOR=4.67, 95%CI:2.77-7.86), no formal education (AOR=14.28, 95%CI: 2.82-71.46), not utilizing eyeglass (AOR=3.94, 95%CI (1.65-9.40). The most possible causes of visual impairment were found to be refractive error and cataract.
Conclusions And Recommendations: The prevalence of visual impairment among study population was relatively high, and more than three-fifths of participants had unilateral visual impairment. Age, marital status, occupation, educational status, wealth index, and not wearing of prescribed eyeglasses were significantly associated with visual impairment. Refractive error is the leading cause of visual impairment. Awareness of spectacle use and expanding cataract surgery coverage are urgently needed in this area.

Speechreading Ability Affects Mandarin Tone Perception in Young Adults With Prelingual Hearing Impairment in China.
J Speech Lang Hear Res
January 2025
Department of Special Education, Central China Normal University, Wuhan.
Purpose: This cross-sectional study explored how the speechreading ability of adults with hearing impairment (HI) in China would affect their perception of the four Mandarin Chinese lexical tones: high (Tone 1), rising (Tone 2), falling-rising (Tone 3), and falling (Tone 4). We predicted that higher speechreading ability would result in better tone performance and that accuracy would vary among individual tones.
Method: A total of 136 young adults with HI (ages 18-25 years) in China participated in the study and completed Chinese speechreading and tone awareness tests.
Changes in Retinal Oxygen Saturation 1 Month After Femtosecond LASIK Treatment in Chinese Adults with Myopia.

Introduction: This study aimed to compare changes in retinal oxygen saturation 1 month after femtosecond-assisted laser in situ keratomileusis (FS-LASIK) in Chinese adults with myopia using retinal oximetry.
Methods: In this prospective, observational, single-center cohort study, Chinese adults aged 18-45 years with myopia were categorized into four groups according to spherical equivalent (SE), with 66 eyes characterized as low myopia (LM -3.00D < SE ≤ -0.
Impact of Multimodal Prompt Elements on Diagnostic Performance of GPT-4V in Challenging Brain MRI Cases.

January 2025
From the Institute of Diagnostic and Interventional Neuroradiology, Klinikum rechts der Isar, School of Medicine, Technical University of Munich, Ismaninger Strasse 22, Munich 81675, Germany.
Background Studies have explored the application of multimodal large language models (LLMs) in radiologic differential diagnosis. Yet, how different multimodal input combinations affect diagnostic performance is not well understood. Purpose To evaluate the impact of varying multimodal input elements on the accuracy of OpenAI's GPT-4 with vision (GPT-4V)-based brain MRI differential diagnosis.

Department of Ophthalmology, Seoul National University College of Medicine, Seoul National University Hospital, Seoul, Korea.
Background: Leber congenital amaurosis (LCA), the most severe form of inherited retinal dystrophy, is a rare, heterogeneous, genetic eye disease associated with severe congenital visual impairment. RPE65, one of the causative genes for LCA, encodes retinoid isomerohydrolase, an enzyme that plays a critical role in regenerating visual pigment in photoreceptor cells.
Methods: Exome sequencing (ES) was performed on a patient with suspected LCA.
