Tear film is a layer of fluid film covering the surface of eye global, which is divided into mucus layer, aqueous layer and lipid layer from inside to outside. The change of each layer composition will lead to tear film instability, resulting in the occurrence of dry eye. On the basis of numerous studies on the correlation between tear composition and tear film break-up patterns, Yokoi and his team proposed new concepts on the diagnosis and treatment of dry eye called tear film-oriented therapy (TFOT) and tear film-oriented diagnosis (TFOD) in 2012 and 2013. That is according to different tear film break-up patterns (TFBUP), so changes in tear film composition can be deduced and supplemented, and this diagnosis and treatment method is gradually being accepted. In this paper, we summarized and analyzed the relationship between different tear film break-up patterns and changes in tear film composition to provide a more scientific and convenient guidance program for the diagnosis and treatment of dry eye.

Idiopathic congenital nystagmus (ICN) is a common ophthalmic disease in which patients often have obvious and characteristic eye abnormalities. ICN patients are often accompanied by learning and social disorders, have a great impact on their physical and mental health. ICN which has an obvious genetic tendency and is mostly manifested as X chromosome linkage (dominant or recessive). Current studies have found that the mutation of FRMD7 gene is the most significant pathogenic factor. In the past 10 years, researchers have done a lot of work on the genetics of ICN and FRMD7 gene, and achieved remarkable results. This review summarizes the typ mutations caused by FRMD7 gene since 2006, and also discusses the possible pathogenesis of FRMD7 mutations, aiming to provide references for scholars to verify previous research results and future research directions.

Objective: To investigate the effect of corneal bandage lens on anxiety and quality of life in patients with monocular cataract. Methods: A total of 120 patients with monocular cataract treated in our department from December 2020 to July 2021 were selected as the subjects. They were divided into an experimental group (wearing corneal bandage lens) and a control group (without corneal bandage lens) by convenient sampling method. Self-rating Anxiety Scale and Visual Function Quality of Life Scale were used to evaluate and compare the degree of anxiety and postoperative quality of life between the 2 groups. Results: There was no significant difference in anxiety score and quality of life score between the 2 groups before admission (P>0.05). On the first day after operation, the anxiety score of the experimental group was significantly lower than that of the control group, and the quality of life score was significantly higher than that of the control group (P<0.05). The anxiety score of patients in the experimental group decreased from 55.35±7.09 to 43.77±5.56, and the degree of anxiety decreased by 20% compared with that before admission. The anxiety score of patients in the control group decreased from 54.27±5.93 to 47.92±7.02, and the degree of anxiety decreased by 12% compared with that before admission. The score of quality of life in the experimental group increased from 55.32±25.57 before admission to 81.01±13.74 on the first day after operation, an increase of 46%. The quality of life score of patients in the control group decreased from 56.38±14.43 before admission to 36.15±17.97 on the first day after operation, a decrease of 35%.Conclusion: Corneal bandage lens can reduce the anxiety of patients with monocular cataract and improve the quality of life after operation.

Objective: To construct, implement and evaluate the effectiveness of the health education model for ophthalmic day surgery. Methods: The health education model for ophthalmic day surgery was constructed relying on information-oriented means and Teach-back method. A total of 177 patients with day surgery in Zhongshan Ophthalmic Center from January 2020 to May 2021 were selected as the research subjects and divided into a control group (n=97) and an intervention group (n=80) by historical comparative study. The intervention group was carried out with the health education model based on information-oriented means and Teach-back method, while the control group received the routine health education. The health education knowledge and perioperative nursing satisfaction were compared between the 2 groups. Results: The scores of self-evaluation and nurse evaluation for health education knowledge in the intervention group were significantly higher than those in the control group (P<0.05). There was no significant difference in body position nursing knowledge score and nursing satisfaction score between the 2 groups (P>0.05). Conclusion: The health education model based on information oriented means and Teach-back method can improve the health education knowledge level of patients with ophthalmic day care surgery. In the meanwhile, further studies will be needed to explore the effects on patients in body position nursing knowledge and nursing satisfaction.

Trauma, infection and congenital diseases may disrupt the tissue structure and cellular homeostasis of the cornea, while causing impaired function of corneal stem cell defects, which in turn may even lead to corneal blindness caused by the inability of the tissue to heal properly. Corneal blindness is one of the major causes of blindness worldwide. Several stem cell-related techniques have been applied to reconstruct functional corneal tissue with impressive therapeutic results. This review focuses on corneal limbal stem cell deficiency and aims to present the current status and recent progress of research on stem cells from multiple sources in corneal reconstruction, as well as to describe specific markers of corneal stem cells.

Objective:To investigate the efficacy of anti-VEGF injection in the treatment of wet age-related macular degeneration (wAMD) for 5 years. Methods: A total of 84 patients (103 eyes) wAMD diagnosed in Department of Ophthalmology in Beijing Hospital from 2011 to 2021 were analyzed retrospectively. 3 + PRN regimen was applied for anti-VEGF treatment. The changes of best corrected visual acuity (BCVA), the number of intravitreal injections and the number of follow-up visits, and the anatomical changes of the lesions in the past 5 years were collected. Results: The average BCVA after 5 years was 38.1 letters, indicating a decrease of 9.4 letters comparing to baseline, which was statistically significant (P<0.001). 23.3% of the eyes could maintain the baseline BCVA after 5 years. The average injection times within 5 years was 13.8, and the injection was concentrated in the first year, with an average of 4.3. The average number of follow-up visits within 5 years was 24.3, and only 34.0% of the affected eyes could keep the follow-up interval ≤3 months. After 5 years, 68.0% of the eyes developed fibrous scar, 27.2% developed geographic atrophy, and 69.0% (71/103) had consistent pigment epithelial detachment. Factors significantly affect BCVA include: age, baseline BCVA, initial treatment, follow-up time, injection times, central retinal thickness, geographic atrophy and so on. Conclusion: Most patients can maintain vision within the first year after anti-VEGF treatment, but the efficacy is poor for more than 5 years. Early diagnosis and treatment, and increased injection frequency may be the research direction for improving prognosis in the future.

Integrating ideological and political concepts of the curriculum into the professional curricula is an important way to implement the fundamental task of cultivating people with morality and comprehensively promote the education of people through the curriculum. Based on the connotation requirements and actual development of the integration of ideological and political education throughout curriculum, considering the features of laboratory skills training courses, this paper explores ideological and political education in 5 aspects. The 5 aspects include knowledge points, humans and society, stories, case analysis, and experimental operation. By optimizing teaching design, innovating teaching methods, and enriching teaching contents, the education of socialist core values should be effectively carried out throughout the whole process of professional course education, which provides a valuable reference for the ideological and political teaching in ophthalmology and molecular medicine related courses and for the cultivation of high-quality talents.

Objective: To investigate the association between myopia and ganglion cell layer and inner plexiform layer(GCIPL) in diabetic population without diabetic retinopathy (DR). Methods: In this Guangzhou Diabetic Eyestudy, a total of 1165 patients aged 30–80 years were recruited followed up longitudinally for 2 years. According tothe presence or absence of myopia [spherical equivalence (SE)≤-3 diopter (D)] and diabetics, the patients weredivided into a healthy group (n=508), a diabetes mellitus group (n=525), and a diabetes mellitus + myopia group(n=132). GCIPL was measured via swept-source optical coherence tomography. Univariable and multivariablemixed models were used to show the association of GCIPL change and baseline parameters. Results: SE was(1.07±1.06) D in the healthy group, (1.02±1.00) D in the diabetes mellitus group and (-5.36±2.30) D in thediabetes mellitus + myopia group (P<0.001). The baseline GCIPL thickness were (71.1±0.3), (74.4±0.2), and(71.7±0.5) μm, respectively. The slope of GCIPL thickness was ?0.10 (95% CI: 0.05 to -2.03) μm/year in the healthy group, which was 12 folds faster than those in the diabetes mellitus group [-1.21(95% CI: 0.05 to-24.04) μm/year, P<0.001] and 22 folds higher among those in diabetes mellitus + myopia group [-2.17 (95%CI: 0.10 to ?21.63) μm/year, P=0.009]. Conclusion: Both myopia and diabetes status accelerate macular ganglioncell layer and inner plexiform layer thinning in diabetic patients without diabetic retinopathy.
