OBJECTIVE:This study was designed to compare the reduction in myopia progression in patients treated with atropine eyedrops alone with patients treated with a combined treatment of atropine and stimulation of the auricular acupoints.

METHODS:This study was a randomized single-blind clinical controlled trial. A total of 71 school-aged children with myopia, who fulfilled the eligibility criteria, were recruited. They were randomly assigned into three groups. These were 22 treated with the 0.25% atropine (0.25A) only, 23 treated with the 0.5% atropine (0.5A) only and 26 treated with 0.25% atropine together with stimulation of the auricular acupoints (0.25A+E). The differences in the post-treatment effects among these three groups were statistically assessed. The primary outcome parameter was myopia progression, which was defined as diopter change per year (D/Y) after cycloplegic refraction measurement.

RESULTS:The mean myopia progression of the 0.25A group was 0.38+/-0.32 D/Y. No significant difference in mean myopia progression was found between the 0.5A (0.15+/-0.15 D/Y) and 0.25A+E (0.21+/-0.23 D/Y) groups. However, there was a markedly reduced myopia progression in the 0.25A+E group compared to the 0.25A group (p<0.05). Furthermore, there was no statistical difference among these three groups in axial length elongation (ALE) of eye during this stage of the investigation.

CONCLUSIONS:This study demonstrates that there was efficacy in stimulating the auricular acupoints and this enhanced the action of 0.25% atropine as a means of myopia control. The result was an effect almost equal to that of 0.5% atropine alone. There is also a need that the ALE of the eye should be further investigated over a longer period using the combined therapy.

OBJECTIVES:To identify and assess the evidence showing the efficacy of auricular acupressure alone for myopia in children and adolescents.

METHODS:Randomized controlled trials (RCTs) that were published until March 2019 in Pubmed, Web of Science, OVID, Foreign Medical Literature Retrieval Service, China Knowledge Resource Integrated Database, The Chinese Biological Medicine Database, Wanfang Database, and Chongqing VIP Information were searched. The quality of RCTs was assessed using the Cochrane risk of bias assessment tool.

RESULTS:Ten RCTs were included to be qualitatively summarized, of which 5 studies qualified for the meta-analysis of the efficacy rate in treating myopia. This review demonstrated that auricular acupressure alone was more effective than eye-drops treatment, eye exercise, and was the just as effective as needle acupuncture.

CONCLUSIONS:Auricular acupressure could slow the progression of myopia in children and adolescents. However, there is a need for further studies with higher methodological quality and sufficient follow-up.

Myopia is a major health problem, not only because of its high prevalence in Asia but also because it contributes to visual morbidity. This study aimed to evaluate the effect of ear acupressure for visual improvement on school children in Taiwan. Participants were fifth-grade school children with visual acuity between 6/37.5 and 6/9.6 in one eye. The experimental group (n = 35) received a 15-week ear acupressure intervention with seed embedding; the control group (n = 35) did not. Data for demographic factors, visual acuity, refractive error, and behavior toward visual health were collected before and after the intervention. The significant differences were observed between the two groups in visual acuity (p = 0.02), refractive error (p = 0.04), and behaviors toward visual health (p = 0.045). Performing ear acupressure may facilitate improved visual health for children. However, it requires more extended studies exploring its effects on elementary students in different grades. Longitudinal effects of this intervention also require further study.

Accumulating evidences suggest that foods that were regularly consumed during the human primates and evolution, in particular during the Paleolithic era (2.6-0.01 x 10(6) years ago), may be optimal for the prevention and treatment of some chronic diseases. It has been postulated that fundamental changes in the diet and other lifestyle conditions that occurred after the Neolithic Revolution, and more recently with the beginning of the Industrial Revolution are too recent taking into account the evolutionary time scale for the human genome to have completely adjust. In contemporary Western populations at least 70% of daily energy intake is provided by foods that were rarely or never consumed by Paleolithic hunter-gatherers, including grains, dairy products as well as refined sugars and highly processed fats. Additionally, compared with Western diets, Paleolithic diets, based on recently published estimates of macronutrient and fatty acid intakes from an East African Paleolithic diet, contained more proteins and long-chain polyunsaturated fatty acids, and less linoleic acid. Observational studies of hunter-gatherers and other non-western populations lend support to the notion that a Paleolithic type diet may reduce the risk of cardiovascular disease, metabolic syndrome, type 2 diabetes, cancer, acne vulgaris and myopia. Moreover, preliminary intervention studies using contemporary diet based on Paleolithic food groups (meat, fish, shellfish, fresh fruits and vegetables, roots, tubers, eggs, and nuts), revealed promising results including favorable changes in risk factors, such as weight, waist circumference, C-reactive protein, glycated haemoglobin (HbAlc), blood pressure, glucose tolerance, insulin secretion, insulin sensitivity and lipid profiles. Low calcium intake, which is often considered as a potential disadvantage of the Paleolithic diet model, should be weighed against the low content of phytates and the low content of sodium chloride, as well as the high amount of net base yielding vegetables and fruits. Increasing number of evidences supports the view that intake of high glycemic foods and insulinotropic dairy products is involved in the pathogenesis and progression of acne vulgaris in Western countries. In this context, diets that mimic the nutritional characteristics of diets found in hunter-gatherers and other non-western populations may have therapeutic value in treating acne vulgaris. Additionally, more studies is needed to determine the impact of gliadin, specific lectins and saponins on intestinal permeability and the pathogenesis of autoimmune diseases.
