Background: Cardiorespiratory fitness (CRF) is a modifiable risk factor for chronic diseases, but its association with depressive symptoms remains unclear, particularly across different populations. We aimed to investigate the link between estimated CRF (eCRF) and incident depressive symptoms among individuals over 50 years old, and to explore potential cross-country variations in this association.

Methods: Data were retrieved from three national cohorts: the Health and Retirement Study (HRS, United States), the English Longitudinal Study of Ageing (ELSA, England), and the China Health and Retirement Longitudinal Study (CHARLS, China).

Corneal neovascularization, a severe pathologic change of the ocular surface, is usually caused by complex pathogeneses, and leads to severe vision damage and eventually corneal blindness. The applications of anti-inflammatory and anti-angiogenic drugs as well as keratoplasty have proved to have certain therapeutic effects. However, there are still numerous barriers that have not yet been fully overcome, prompting a trend towards treatment with multidisciplinary techniques.

Background: Transepithelial photorefractive keratectomy using Smart Pulse Technology (SPT-TransPRK) is currently the leading method for superficial refractive surgery, offering advantages such as a non-contact procedure, shorter operation times, and excellent patient cooperation. Laser ablation of the corneal epithelium, Bowman's membrane, and the stroma can effectively correct refractive errors. Thus, the complete healing of the corneal epithelium post-surgery is essential for ensuring good vision.

Article Synopsis
  • This study compared the pupil offset measurements from three devices: Pentacam, Keratron Scout, and Sirius, in 146 young myopic patients scheduled for refractive surgery.
  • Researchers analyzed the measurements of pupil deviation and found the devices yielded similar results with good consistency.
  • The findings suggest that these devices can be reliably used in clinical settings for measuring pupil shifts in young myopic individuals.

  • - Pet ownership is linked to a higher risk of dry eye symptoms (DES), with a prevalence of 43.6% found in a study of 21,916 Chinese residents aged over 12 during a nationwide survey.
  • - The study revealed that pet owners had a 13% increased risk of developing DES, which was even higher among elderly (28% increase) and urban residents (13% increase).
  • - The interaction between pet ownership and allergic rhinitis showed a significant combined effect on DES, indicating potential common underlying mechanisms between these conditions.

Topical ophthalmic solutions (eye drops) are becoming increasingly popular in treating and preventing ocular diseases for their safety, noninvasiveness, and ease of handling. However, the static and dynamic barriers of eyes cause the extremely low bioavailability (<5%) of eye drops, making ocular therapy challenging. Thus, drug-eluting corneal contact lenses (DECLs) have been intensively investigated as a drug delivery device for their attractive properties, such as sustained drug release and improved bioavailability.

Article Synopsis
  • The study aimed to establish standardized corneal densitometry (CD) values in healthy Chinese individuals and analyze how factors like sex, age, and ocular parameters affect corneal density.
  • Using a Scheimpflug camera, CD measurements were taken from 990 participants, revealing an average CD of 16.26 GSU, with significant density differences across corneal depths and radial areas.
  • Results indicated that while average CD did not significantly differ by sex, females had higher CD values after adjusting for age and other ocular parameters, and age-related changes in CD were observed except in the 2-6 mm radial area.

Background: Myopia has recently emerged as a significant threat to global public health. The high and pathological myopia in children and adolescents could result in irreversible damage to eye tissues and severe impairment of visual function without timely control. Posterior scleral reinforcement (PSR) can effectively control the progression of high myopia by limiting posterior scleral expansion, improving retrobulbar vascular perfusion, thereby stabilizing the axial length and refraction of the eye.
