Objectives: To evaluate the reliability of optical biometry for correct intraocular lens (IOL) power calculation in eyes with macula-off rhegmatogenous retinal detachment (RRD) via comparing the axial lengths (AL) measured with optical biometry preoperatively and postoperatively.
Methods: This retrospective study was conducted with 25 eyes of 25 patients who underwent combined surgery (phacoemulsification and pars plana vitrectomy (PPV)) with the diagnosis of RRD with macular involvement. Best-corrected visual acuity (BCVA), biomicroscopic examination, intraocular pressure measurement and full fundoscopic examination were performed in all patients. Axial length was measured using optical biometry in all patients. The AL measurements were repeated in the postoperative third month in the patients using gas tamponade during vitreoretinal surgery and in the third month after the silicone oil removal in patients using silicone-oil tamponade during vitreoretinal surgery.
Results: The mean age of the patients was 61.60±7.33. Fifteen patients (60%) were female, and 10 (40%) were male. Postoperative BCVA values (0.40±0.28) were significantly higher than the preoperative BCVA values (0.14±0.22) (p<0.05). The preoperative mean value of AL was measured as 24.66±1.90 and the postoperative mean value of AL was 24.67±1.91. There was no statistically significant difference between the measured AL values in the preoperative and postoperative periods (p=0.258).
Conclusion: Combined surgery (phacoemulsification and PPV) is a frequently applied method in RRD treatment. The correct AL measurement is important for the removal of refractive errors due to AL measurement in patients with macula-off RRD. Optical biometry provides accurate results in these cases.

Differences in Ocular Biometry Between Short-Axial and Normal-Axial Eyes in the Elderly Japanese.

Purpose: Among patients with angle-closure glaucoma, it is common to have a short-axial eye, which also makes it difficult to select an appropriate intraocular lens. Previous studies have focused on the ocular biometry of the long-axial eye, whereas only a few reports have focused on the short-axial eye. This study aimed to clarify the characteristics of the short-axial eye on ocular biometry among the elderly Japanese.

This review offers a comprehensive and in-depth analysis of face mask detection and recognition technologies, emphasizing their critical role in both public health and technological advancements. Existing detection methods are systematically categorized into three primary classes: feaRture-extraction-and-classification-based approaches, object-detection-models-based methods and multi-sensor-fusion-based methods. Through a detailed comparison, their respective workflows, strengths, limitations, and applicability across different contexts are examined.

Interdisciplinary examination of test materials requires careful consideration of how forensic routines can influence each other. This influence can be direct and obvious, or indirect and subtle. A multidisciplinary collaborative exercise (MdCE) should test a forensic laboratory's ability to account for these difficulties.

To investigate the pattern and threshold of physiological growth, defining as axial length (AL) elongation that results in little refraction progression, among Chinese children and teenagers, a total of 916 children aged between 7 and 18 years from a 6-year longitudinal cohort study were included for analysis. Ocular biometry, cycloplegic refraction and demographic data were obtained annually. Physiological growth was calculated based on myopic progression and Gullstrand eye model, respectively.
