Purpose: To evaluate mean central corneal thickness (CCT) in a Puerto Rican population and to compare our findings with published mean central corneal thicknesses of white, Hispanic, and African American populations in the United States.
Patients And Methods: Volunteers at the Centro Médico, San Juan, Puerto Rico, completed a survey and participated in an eye examination, which included measurement of intraocular pressure and central corneal thickness.
Results: Of 588 Puerto Rican participants, the mean CCT was 541+/-33 microm, which is significantly thinner than the published values for white populations (P<0.002) and Hispanic populations (P<0.03), but thicker than the published values for African Americans (P<0.05). Among ethnic subgroups in Puerto Rico, no significant differences in the mean CCT were observed.
Conclusions: In this Puerto Rican population, the mean observed CCT was thicker than that published for African Americans, but thinner than those for white and other Hispanic populations within the United States.

Purpose: This study compares the corneal temperature in dry eyes with normal eyes via high-resolution infrared thermography.
Methods: A total of 86 participants were enrolled, with 40 and 46 participants in the dry eye disease (DED) and control groups, respectively. All participants underwent non-invasive breakup time (NIBUT) measurement, an Ocular Surface Disease Index (OSDI) questionnaire and ocular thermography.
Factors Associated with Corneal Hysteresis in an Elderly White Population: The Thessaloniki Eye Study.

Laboratory of Research and Clinical Applications in Ophthalmology, Aristotle University of Thessaloniki, Thessaloniki, Greece.
Prcis: In 801 participants, corneal hysteresis (CH) was positively associated with female gender and central corneal thickness, and negatively with age and axial length. Diabetes showed no significant association with CH in the adjusted models.
Purpose: To provide values of corneal hysteresis (CH) in an elderly, healthy Greek population and to investigate its association with demographic, ocular, and systemic factors.
A study on the variability and correlation of ocular biological measurement parameters in adult myopic patients.

Shenzhen Eye Institute, Shenzhen Eye Hospital, Jinan University, Shenzhen, Guangdong, China.
Objective: This study aims to explore the differences in ocular parameters among adult myopic patients with different degrees of myopia and axial lengths, and to investigate the correlations between these ocular parameters.
Methods: This single-center observational study collected clinical data from myopic patients aged 18-45 years who visited the Eye Hospital of Nanjing Medical University between January and June 2023. The data included laterality, diopter of spherical power (DS), diopter of cylindrical power (DC), spherical equivalent (SE), axial length (AL), central corneal thickness (CCT), flat meridian keratometry (K1), steep meridian keratometry (K2), mean keratometry (Km), anterior chamber depth (ACD), corneal radius of curvature (CRC), and axial length/corneal radius of curvature ratio (AL/CRC).

Keratoconus (KC) is a corneal disorder characterized by central corneal protrusion and thinning. In this study, spatial transcriptomics was employed to investigate molecular and cellular variations in KC, revealing a distinct pattern of inflammatory responses across the cornea. Upregulation of inflammatory processes was observed in the central cornea, while downregulation was noted in the periphery, indicating complex regional inflammatory changes in the KC cornea.

Objectives: To evaluate scleral thickness of patients with keratoconus by anterior segment optical coherence tomography (AS-OCT).
Materials And Methods: Fifty-two eyes of 42 patients with keratoconus (group 1) and 42 right eyes of 42 healthy individuals (group 2) were included. Scleral thickness measurements were taken with AS-OCT 6, 4, and 2 mm behind the scleral spur in four gaze positions: superior, inferior, temporal, and nasal.
