Changes of angle Kappa and corneal morphology changes in myopic patients after Sub / 中南大学学报(医学版)

OBJECTIVES@#To investigate angle Kappa and diopter distribution in myopic patients and the changes of angle Kappa and corneal morphology after Sub-Bowman-Keratomileusis (SBK), and to analyze the effects of the surgery on corneal morphologic changes and the patients' near fixation characteristics.@*METHODS@#The clinical data of 134 myopic patients (268 eyes) undergoing SBK from August 2015 to August 2016 were retrospectively analyzed. Angle Kappa, corneal curvature in the central corneal region of 3 mm, and post-corneal Diff value were measured by Orbscan IIz Corneal Topography System before operation, 1 month and 6 months after operation. According to the values of angle Kappa before SBK, the patients were divided into 2 groups: the large K group (angle Kappa≥5°, 71 eyes) and the small K group (angle Kappa<5°, 197 eyes). Correlation analysis of the factors influencing angle Kappa at 6 months after operation was performed.@*RESULTS@#In the large K group, angle Kappa was (5.67±0.65)°, spherical equivalent was (-4.84±2.32) D, and angle Kappa was decreased after operation (both @*CONCLUSIONS@#The angle Kappa is decreased in low-moderate myopia patients with large angle Kappa, while is increased in high myopia patients with small angle Kappa after SBK. Myopia patients after SBK will look for the new balance of the binocular accommodation and vergence function for improving the comfort in the near-work situations.

Research on improving the core competency of ophthalmological residents by lecturer training / 中华医学教育探索杂志

The lifelong teaching and learning abilities based on training the core competency of ophthalmology residents is a new hot spot in the curriculum design of ophthalmological standardized residency training. In the standardized residency training base of Xiangya Hospital of Central South University Ophthalmic Center, a graded lecturer training curriculum with residents as core has been designed to train the critical thinking, active learning, summarizing and presenting skills of residents at all levels. According to the different tasks, the residents can present themselves through online and offline platforms so that they can gradually grow into different levels of lecturers. Through the graded training of lecturers from low level to high level, step by step, the residents are trained as active learners from the thinking mode, become student-instructors or lecturers from the teaching ability, and be more competent for future study and work.

Accuracy of three common optometry methods in examination of refraction in juveniles / 中南大学学报(医学版)

OBJECTIVE@#To compare the results of the three methods of Suresight handheld autorefractor, table-mounted autorefractor and retinoscopy in examination of juveniles patients with or without cycloplegia.
@*METHODS@#Firstly, 156 eyes of 78 juveniles (5 to 17 years old) were examined by using WelchAllyn Suresight handheld autorefractor and NIDEK ARK-510A table-mounted autorefractor with or without cycloplegia; secondly, retinoscopy was performed with cycloplegia.
@*RESULTS@#The spherical power measured by methods without cycloplegia were significantly greater than those measured with cycloplegia (P0.05). These results were highly consistent, suggesting a tendency towards a short sight. However, the spherical power and cylindrical power measured by table-mounted autorefractor was significantly different (P<0.05); with cycloplegia, there was significant difference in spherical power between Suresight handheld autorefractor and retinoscopy (P<0.05).
@*CONCLUSION@#Cycloplegic retinoscopy is necessary for juvenile refraction examination. Under natural pupil situation, Suresight handheld autorefractor is better than table-mounted autorefractor, though both show a myopia tendency. Nevertheless, table-mounted autorefractor can be taken as a recommendation for the prescription of lens trial. As a strong reference for subjective optometry, retinoscopy should be the gold standard for measuring refractive errors.

Clinical observation of the effect of severe blepharoptosis correction with modified frontalis muscle suspension / 中国医师杂志

Objective To explore clinical observation of the effect of severe blepharoptosis correction with modified frontalis muscle suspension.Methods Thirty three cases (41 eyes) with congenital severe blepharoptosis were treated with modified frontalis muscle suspension,and the operative effect was analyzed retrospectively.Double eyelid incision and concealauxiliary incision on partial-bitamporal of the superciliary arch were adopted.After taking the frontal muscle flap crossed through the subcutaneous tunnel between two incisions and fixed on the superior tarsus.Closed palpebral fissure with suture method after adjustment was satisfied.Results At 1 ～ 24 (9.76 ± 5.15) months post-operatively,all incisions of 33 cases were primary healing,eyelid radian satisfaction and no corneal exposure complication occurrence.The early postoperative reaction was mild,while only 1 case discovered subcu-taneoushematoma in superciliary arch.The satisfactory corrections were 30 cases,which undercorrections were 2 cases and 1 case was over correction.No palpebral and exposed keratotitislong-tern complication was found.Conclusions The operation of modified frontalis muscle suspension is satisfactory,safe and effective with little complications and less injury in intraoperative.
