The myopia rate of children and adolescents is increasing, which has different degrees of negative impact on visual health, physical and mental development and quality of life. External treatment of traditional Chinese medicine has a good effect in the clinical treatment of mild myopia in children and adolescents. This article will summarize the research progress of appropriate traditional Chinese medicine techniques such as acupuncture, massage, moxibustion, ear pressure pills, gua sha, and external use of traditional Chinese medicine in the treatment of mild myopia in children and adolescents. In order to provide clinical treatment ideas for the clinical treatment of mild myopia in children and adolescents.
Objective: Constructing evaluation indicators for intraoperative cooperation of patients undergoing femtosecond laser small incision corneal stromal lens extraction surgery (SMILE), providing scientific basis for objectively evaluating and guiding intraoperative cooperation of SMILE patients. Method: A research group was established, and based on literature review and clinical research, a combination of qualitative interviews and quantitative research was used to construct an evaluation index for intraoperative compliance of patients undergoing femtosecond laser small incision corneal stromal lens extraction surgery (SMILE). The Delphi method was used to conduct two rounds of consultations with 20 experts, and the consultation results were statistically analyzed. Result: The response rates of the two rounds of expert inquiry questionnaires were 95% and 94.7%, with expert authority coefficients of 0.90 and 0.89. Finally, five evaluation indicators for intraoperative compliance of patients undergoing femtosecond laser small incision corneal stromal lens extraction surgery (SMILE) were constructed. The second round of coordination coefficient is 0.4 (P<0.01); Conclusion: The evaluation indicators of intraoperative cooperation in patients undergoing femtosecond laser small incision corneal stromal lens extraction surgery (SMILE) have been tested, and expert opinions are concentrated. The results are scientifically reliable and can provide objective evaluation reference for the clinical practice of femtosecond laser small incision corneal stromal lens extraction surgery (SMILE), and scientific cooperation guidance for surgical patients.
Meibomian gland dysfunction is the main cause of hyperevaporative dry eye, and the lack of specificity in the early stage is often ignored, resulting in meibomian gland atrophy over time and affect visual function. Due to the impact of vibration, loading, meteorological conditions, flight distance and other factors in the special occupation of flight personnel, as well as the narrow training space, reduced air humidity, high mental tension and other factors, it is easy to cause symptoms such as dry eyes, visual fluctuations or even obvious decline. The use of artificial tears alone cannot restore the health of the eyes. It has great influence on the physical and mental health of flight personnel and flight operations. Therefore, this paper aims to review the etiology, clinical manifestations and comprehensive treatment of meibomian gland dysfunction related dry eye in flight personnel, in order to provide clues and ideas for the special population eye health protection.
Artificial intelligence retinal screening technology is gradually becoming a new and effective detection method. Deep learning (DL) models are considered the most advanced technology in artificial intelligence (AI). In ophthalmology research, more and more scholars focus on the application of deep learning technology (DL) in the diagnosis and treatment of ophthalmic diseases, aiming to improve the efficiency and accuracy of ophthalmic disease diagnosis and treatment. This article aims to introduce the technical principles of deep learning, its application in ophthalmology, and analyze the current application challenges of this technology.
Objective: To evaluate the efficacy and safety of ultrapulse carbon dioxide (CO?) laser in the treatment of various types of eyelid lesions. Methods: The study included 50 patients with eyelid lesions (12 male, 38 female). The age of the patients ranged from 4 to 84 years, with an average age of 37.9±20.0 years. Types of lesions included eyelid pigmented nevi, xanthelasma, divided nevus, and molluscum. Among them, 25 lesions involved the gray line of the eyelid and 10 had a diameter greater than 10 mm. All patients underwent ultrapulse CO? laser treatment and were followed up postoperatively. The treatment outcomes were assessed through digital photos, and complications were documented within 1 month after treatment. Results: The total cure rate for the 50 eyelid lesions was 92%, with a total effective rate reaching 100%. Four cases of eyelid pigmented nevi recurred within one month after treatment, while all other patients achieved clinical cure. Postoperative complications mainly included minor trichiasis (5 cases), partial sparse to absent eyelashes (4 cases), and hypertrophic scar with hyperpigmentation (4 cases). Conclusion: For eyelid lesions, particularly those on the eyelid margin and larger lesions, the ultrapulse CO? laser provides a more precise, minimally invasive, and effective treatment method. It can serve as a preferred treatment option for eyelid lesions and is worthy of clinical promotion.
Background: To compare two swept-source optical coherence tomography (SS-OCT) biometers,IOLMaster 700 and ANTERION.Methods: This is a retrospective study. Biometric measurements of cataract patients performed between March and July 2021 in the Department of Ophthalmology, United Christian Hospital, Hong Kong, were reviewed. Patients scheduled for cataract surgery were measured with both SS-OCT devices on the same day.The following biometry parameters were compared: keratometry (K), total keratometry (TK), axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), white-to-white (WTW) and the predicted intraocular lens (IOL) power to achieve emmetropia. To assess the agreement between the devices, Bland-Altman analysis with 95% limits of agreement (LoA) were used.Results: In total, 92 eyes of 47 subjects were measured with both devices. There were statistically significant differences between the two biometers for most measurements (P<0.05) except for flat K, AL and IOL power when using the right eyes for analysis. For the left eyes, there were statistically significant differences in the measurements from the two biometers in all parameters except for flat and steep K. The ANTERION did not obtain ACD, AL and LT in 2 (2.17%), 1 (1.09%) and 5 cases (5.43%) respectively.Conclusions: The two biometers showed a clinically acceptable agreement in most parameters. Comparisons showed significant differences in most parameters but not clinically relevant except for the TK and WTW, and these two parameters should not be used interchangeably between the devices.
Background: A variety of experimental animal models are used in basic ophthalmological research to elucidate physiological mechanisms of vision and disease pathogenesis. The choice of animal model is based on the measurability of specific parameters or structures, the applicability of clinical measurement technologies, and the similarity to human eye function. Studies of eye pathology usually compare optical parameters between a healthy and altered state, so accurate baseline assessments are critical, but few reports have comprehensively examined the normal anatomical structures and physiological functions in these models.Methods: Three cynomolgus monkeys, six New Zealand rabbits, ten Sprague Dawley (SD) rats, and BALB/c mice were examined by fundus photography (FP), fundus fluorescein angiography (FFA), and optical coherence tomography (OCT).Results: Most retinal structures of cynomolgus monkey were anatomically similar to the corresponding human structures as revealed by FP, FFA, and OCT. New Zealand rabbits have large eyeballs, but they have large optic disc and myelinated retinal nerve fibers in their retinas, and the growth pattern of retinal vessels were also different to the human retinas. Unlike monkeys and rabbits, the retinal vessels of SD rats and BALB/c mice were widely distributed and clear. The OCT performance of them were similar with human beings except the macular.Conclusions: Monkey is a good model to study changes in retinal structure associated with fundus disease, rabbits are not suitable for studies on retinal vessel diseases and optic nerve diseases, and rats and mice are good models for retinal vascular diseases. These measures will help guide the choice of model and measurement technology and reduce the number of experimental animals required.
