Vision was measured using the distant vision test method specified in the 2014 National Student Physical Fitness and Health Survey (V1), the 2019 National Student Physical Fitness and Health Survey (V2), and Specification for Screening of Refractive Error in Primary and Secondary School Students (WS/T 663-2020) (V3). The paired samples McNemar s test and Wilcoxon test were performed to compare the detection rate of poor vision and the difference between the visual acuity test results of the three methods.@*Results@#The results of the 98 children examined according to V1, V2, and V3 showed that the M (P25, P 75 ) of the right eye were 4.8（4.6，5.0），4.8（4.7，5.0），and 4.8（4.7，5.0）while the left eye visual acuity M ( P 25 , P 75 ) were 4.8 （4.6，5.0），4.9（ 4.7 ，5.0），and 4.9（4.7，5.0），respectively. The rates of poor visual acuity detection for the right eye were 63.3%, 58.2% and 58.2 % for V1, V2, and V3, respectively, while for the left eye, they were 58.2%, 54.1% and 53.1%, respectively. McNemar test results showed that there were no statistically significant differences in the rates of poor visual acuity detection between the right and left eyes for V1 vs. V2, V1 vs. V3, and V2 vs. V3 (left eyes： χ 2=2.25，2.29，0.00，right eyes： χ 2=3.20，3.20，0.00， P >0.05).Wilcoxon test results indicated that there were statistically significant differences between the right and left eye visual acuity groups for V1 vs. V2 and V1 vs. V3 (left eyes： Z =-4.15，-4.60, right eyes： Z = -4.70，-4.99, P <0.01).@*Conclusion@#Irrespective of whether the starting visual standard starts at row 4.0 or 5.0, different standards of visual standard passage have an impact on the visual acuity results. It is recommended that existing methods of screening for distance vision are standardized.

Assessment of knowledge, attitude, and practice of glaucoma among different cadres of optometrists

Purpose: To assess the level of knowledge, attitude, and clinical practice of glaucoma among optometry students and optometry practitioners with different years of clinical experience and academic background. Methods: A survey with 20 questions on knowledge, attitude, and practice (KAP) of glaucoma was prepared and self?administered to optometry students and optometry practitioners practicing in an eye hospital/clinic/optical with varied years of clinical experience and education qualification. Results: Among the 558 participants, 57% were optometry practitioners and 43% were students. The knowledge scores among optometry practitioners increased significantly with an increase in the years of clinical experience (P < 0.001). Participants with master’s degrees scored higher than participants with bachelor’s degrees (P = 0.12). There was no statistically significant difference in knowledge scores based on the type of clinical practice ? hospital, private practice, or optical (P = 0.39). Practicing optometrists who performed slit?lamp examination, gonioscopy, IOP measurements, and disc evaluation for the detection of glaucoma had significantly higher knowledge scores than those who did not perform these tests in their practice (P < 0.05). A positive attitude toward glaucoma learning through workshops and hands?on training was reported by optometrists and students. Conclusion: Knowledge about glaucoma was good among optometrists and optometry students and was better among those who handled the diagnostics. All the optometrists had a positive attitude toward enhancing their practice through proper training

Progress of application of adaptive optics in ophthalmology / 中华实验眼科杂志

Adaptive optics (AO) can measure and correct wavefront aberrations in real time, which enables the optical system to adapt to external changes and maintain excellent optical performance, and has been gradually paid attention in the field of ophthalmology.AO technology can carry out optometry according to wavefront aberrations to improve the efficiency and accuracy of subjective and objective refraction, eliminate the influence of ocular aberrations on retinal imaging, provide more accurate data for the evaluation of optic nerve function, improve the effectiveness of visual perception training and provide vision care and treatment for special people, as well as simulate and predict postoperative visual outcome and give personalized schemes for refractive surgery and intraocular lens implantation.Moreover, AO combined with optical coherence tomography, optical scanning laser ophthalmoscope, and confocal scanning laser ophthalmoscope, can realize fundus imaging and retinal vascular imaging in real time, provide better sensitivity and resolution of retinal detection, distinguish fine details of retinal vessels and cone cells, and characterize retinal pigment epithelium topology and deformation, the application of which in posterior segment laser surgery, glaucoma diagnosis and follow-up, color blindness and retinal physiological activity research has been attracting attention.In this article, the principle and application of AO in ophthalmology were briefly reviewed.

Introduction. Amblyopia is a visual disorder that arises during cortical development, and is considered the most frequent cause of preventable blindness. Early diagnosis and treatment have been demonstrated to be highly effective. However, it is often detected at a late stage, partly due to lack of knowledge. The purpose of this article is to describe the perceived knowledge of general practitioners and pediatricians in Bucaramanga on the early detection of amblyopia. Methodology. A descriptive, qualitative exploratory study was performed, by means of semistructured interviews of 20 healthcare professionals, using the approach suggested by Taylor and Bogdan. Results. The interview results found two types of issues: shortcomings in undergraduate and graduate training, lack of infrastructure to perform the visual assessment. It also detected four sub-categories, including incorrect concepts about amblyopia, lack of clarity about the right age to perform the first-time visual assessment, and erroneous beliefs about the assessment and referral to specialized optometry and ophthalmology services. Discussion. The study found gaps in knowledge by healthcare professionals as well as the different contributing factors to this problem, and indicates the importance of strengthening this subject in the curricula. Conclusion. It is necessary to strengthen knowledge among general practitioners and pediatricians to enable the early detection of children at risk of amblyopia and reduce the burden of this disease.

El 86,6% del meridiano eje (ME) del OD está entre 38,00 y 43,88 dpt, en tanto que el 87,2% del ME del OI se encuentra entre 32,00 y 43,88 dpt. La ametropía positiva para el OD está entre 0,25 y 8,00 dpt; para el OI en 0,25 y 7,50dpt. La ametropía negativa está en 6,00 para el OD y 6,50 dpt para el OI como valores máximos. En relación a la curvatura corneal y a las ametropías, el OD muestra una correlación de Pearson negativa, de -0,21 (p=0.0001). En el OI la correlación de Pearson también es negativa, de -0,20 (p=0.0001). Por lo tanto, la relación encontrada entre estas dos variables es tan solo del 5,1% y un 4,7% para OD y OI, respectivamente. Conclusiones: la relación entre la curvatura corneal y los errores de refracción según este modelo solo explica un porcentaje insignificante que no tiene importancia clínica, es del 4,9% en promedio del valor obtenido en el error refractivo en ambos ojos. Por ello, no es posible hacer una predicción de los errores refractivos con base en el radio de la curvatura corneal.

Objective: The purpose of this research was to determine the relationship between corneal curvature and refractive errors in schooled population between the ages of 5 to 19 in the city of Pereira in 2014. Materials and Methods: This is a descriptive correlational observational study, in which the simple linear regression model between keratometry and retinoscopy is indicated. Through static retinoscopy and keratometry, refractive error was evaluated in 915 students of Pereira. Results: The cylindrical value obtained for the RE (right eye) oscillates between -0.12 and -5.50 dpt and for the LI (left eye) -0.12 and -6.12 dpt, where 86.6% of the Axis (ME in Spanish) RE is between 38.00 and 43.88dpt, while 87.2% of Axis LE is between 32.00 and 43.88dpt. The positive ametropia for the RE is between 0.25 and 8.00dpt, for the LE 0.25 and 7.50dpt, the negative in RE 6.00 and OI 6.50dpt as maximum values. In relation to corneal curvature and ametropias, the RE shows a negative Pearson correlation of -0.21 (p = 0.0001). In the LE the Pearson correlation is also negative, of -0.20 (p = 0.0001). Therefore, the relationship found between these two variables is only 5.1% and 4.7% for RE and LE respectively. Conclusions: The relationship between corneal curvature and refractive errors according to this model only explains an insignificant percentage that does not have clinical importance, it is a 4.9% on average of the value obtained in the refractive error in both eyes, therefore, it does not allow a prediction of refractive errors based on the radius of corneal curvature.

A relação entre a curvatura corneana e os erros refra-tivos de acordo com este modelo explica apenas uma percentagem insignificante de nenhuma importância clínica, é de 4,9%, em média, do valor obtido no erro refrativo em ambos os olhos, de modo que, não permite fazer uma previsão de erros refrativos com base no raio da curvatura corneana.

Establishment and practice on collaborative education model of "medicine, teaching, research and prevention" in Optometry / 中华医学教育探索杂志

In order to satisfy the social and medical demands for optometric talents, the education model combining "medicine, teaching, research and prevention" was established, fully integrated with various resources like talents, facilities, equipment from the affiliated eye hospital, institute of ophthalmology and prevention and treatment center for juvenile myopia. Cultivation of high-quality applicative talents which integrated "knowledge, skills and accomplishment" were taken as the main line, Cultivation goal was established in accordance with requirement of talent. The curriculum system was optimized on the basis of competence. The teaching mode was reformed to "2+2" mode, "double-position teachers" became the requirement for the teaching staff and professional education comprehensive practice platform of "one entity, two wings" was constructed, with good effectiveness being achieved.

Analysis and inspiration of American optometrist teaching system / 中华医学教育探索杂志

The optometrist education system in the United States has a history of more than 100 years and has become a complete and mature system. It contains five parts: optometry admission test (OAT); a complete curriculum of optometry, including basic medical lectures, optometric theories and skills, large amount of clinical practices; the National Board Exam of Optometry (NBEO) which is mandatory for every licensed optometrist/practitioner, a one-year optional resident program; continue education in every year for renewing optometric licenses. We analyzed differents such as the enrollment requirements, the training time, the graduation requirements and the career perspective of the optometry education system between China and the United States were analyzed, we want to develop a optometrist training system with Chinese characteristics.
