Article Abstract
Objectives: To compare the suitability of the Standard Patient Evaluation of Eye Dryness (SPEED) and the Ocular Surface Disease Index (OSDI) among Chinese college students, and to further validate the SPEED questionnaire by using the OSDI in a non-clinical sample.
Methods: This cross-sectional study involved 1,084 students from Nanyang Medical College, aged 18 to 21 years. The students completed the OSDI and SPEED questionnaires to assess dry eye symptoms. The correlation between the scores of the two questionnaires was analyzed to assess criterion validity. Based on the OSDI scores, a receiver operating characteristic curve was constructed to determine the area under the ROC curve and the cut-off point for evaluating the diagnostic threshold of the SPEED questionnaire.
Results: The Cronbach's alpha values for the OSDI and SPEED questionnaires were 0.943 and 0.911, respectively. Notably, only 281 participants (25.92%) completed all 12 questions in the OSDI questionnaire, whereas all participants completed the SPEED questionnaire without omitting any questions. The mean SPEED scores Full were 3.71, 11.57, 13.84, and 19.72 for each subgroup. Posthoc testing revealed statistically significant differences between all groups (P < 0.05). A significant correlation was observed between the OSDI score, the SPEED score, and the SPEED score Full, particularly between the SPEED score and the SPEED score Full.
Conclusion: In comparison to the OSDI questionnaire, the SPEED questionnaire demonstrates a favorable response rate, reliability, and validity in differentiating dry eye symptoms among Chinese college students. It may be more appropriate for diagnosing dry eye and conducting epidemiological studies within this population.

Restless Eyes at Night: A Novel Variant of Restless Legs Syndrome.
Eur J Case Rep Intern Med

Department of General Medicine, Chiba University Hospital, Chiba, Japan.
Introduction: Restless legs syndrome (RLS) is a common sensorimotor disorder that primarily affects the lower extremities. This condition is characterized by unpleasant sensations and an irresistible urge to move the affected body regions, typically during periods of rest or at night. While RLS most commonly involves the legs, atypical variants affecting other body parts, including the arms, abdomen, face, and even the head, have increasingly been reported.

Department of Ophthalmology, The Second Affiliated Hospital of Anhui Medical University, Hefei, 230601, People's Republic of China.
Objective: To investigate the prevalence of dry eye disease (DED) among children and adolescents aged 9 to 19 years in Fengyang County, and to explore the associations of sleep duration and social jetlag with DED, with the aim of providing scientific evidence for sleep-based interventions to prevent DED in this population.
Methods: Between November and December 2023, 14 primary and secondary schools were randomly selected in Fengyang County, Chuzhou City, Anhui Province, China. Students from Grade 4 to Grade 12 (aged 9-19 years) were invited to participate.
Comparative Validation of MOPTIM MRT-200 Refraction Device with 2WIN and Retinomax.

Alaska Blind Child Discovery, Alaska Children's EYE & Strabismus, Anchorage, Alaska, 99508, USA.
Background: Portable sphero-cylinder refraction is useful for remote medical missions and self-checking. A novel, inexpensive, handheld optical scope with an internal vision chart and adjustable diopter lens, called the Moptim MRT-200, was therefore validated.
Methods: Young, capable patients from a pediatric eye practice had dry refraction estimates with the Moptim MRT-200, Adaptica 2WIN photoscreener, and Monocular Retinomax compared with actual refined retinoscopy.
