Glaucoma is the second leading cause of blindness and the most common cause of irreversible blindness worldwide. Primary angle closure glaucoma (PACG) accounts for 25% of glaucoma. Laser peripheral iridotomy(LPI) has become the first line treatment for PACG and primary angle closure (PAC). The mechanism of LPI is to use laser to create a hole in peripheral iris to relieve pupil block, deepen anterior chamber, expand chamber angle,restore pathway of physiological aqueous discharge and reduce intraocular pressure. Studies have shown that LPI can control intraocular pressure well in all stages of PAC, which is safe for PAC.
Primary Sj?gren’s syndrome is an autoimmune disease that mainly affects exocrine glands. Patients usually refer to ophthalmologists because of severe dry eye symptoms. Most clinicians have insufficient knowledge with dry eye disease associated with primary Sj?gren’s syndrome probably leading to misdiagnosis or missing the diagnosis.The diagnosis of Sj?gren’s syndrome dry eye disease (SS-DED) is difficult, but the extremely invasive objective examination and the development of biomarkers will help to understand this disease and explain its pathogenesis from a new perspective. There is no specific treatment for the SS-DED, and most patients should receive multiple treatments to select the optimal treatment.
Objective: To explore the ocular surface recovery after surgical treatment of strabismus patients. Methods: A total of 92 patients (126 eyes) with strabismus who underwent surgery in our hospital from January 2015 to June 2018 were enrolled. The patients were divided into three groups according to the surgical incision, 42 patients (52 eyes)underwent limbal incision were in group A, 17 patients (19 eyes) underwent trans-muscle end-point incision in group B, and 33 patients (55 eyes) underwent proximal hernia incision in group C. According to the number of muscles involved in the operation, the sick eyes of patients were divided into three groups. The 29 eyes with a single extraocular muscle were a single muscle group, the 42 eyes with 2 extraocular muscles were a double muscle group, and the 21-eye treated with 3 extraocular muscles were a three-muscle group. The ocular surface health recovery time of patients with different incision types and muscle involvement were compared. Results: The first tear film rupture recovery time and tear river height time between group A, B, and C were significantly different,and the data were statistically significant (P<0.05); the first tear film rupture recovery time (14.33±3.26) d and tear river height time (14.54±1.58) d in group A were significantly lower than those in group B and C. The data were statistically significant (F=4.876, P=0.032; F=4.612, P=0.036). The first tear film rupture recovery time and tear river height time between the single, double and three muscle groups were significantly different, and the data were statistically significant (P<0.05); the first tear film rupture recovery time (13.42±3.57) d and tear river height time (8.65±1.62) d were significantly lower in the single muscle group than in the double muscle group and the third muscle group. The data were statistically significant (F=4.975, P=0.028; F=5.024, P=0.025). Conclusion:The number of muscles involved in the operation and the type of surgical incision have an important impact on the health of the ocular surface after surgery. The proximal ankle incision and less number of muscles involved would improve the postoperative recovery of eye health.
Objective: To compare the difference of visual acuity measured by C-chart and E-chart in the same myopic refractive undercorrection and to explore the causes of the difference. Methods: Two hundred and fifty subjects of different ages were selected to compare the changes of visual acuity measured by two different visual meters after adding corresponding spherical lenses to the maximum plus to maximum visual acuity (MPMVA) corrected diopter. At the same time, according to the design principle of the two kinds of visual acuity meters and the different recording methods of visual acuity tables, the possible reasons for the different values were discussed.Results: There was no significant difference between different age groups (P>0.05). Under the same degree of additionality, the visual acuity of the same subjects was tested by t-test with C visual acuity chart and E visual acuity chart. The difference was statistically significant (t=?15.798, P<0.05). The average visual acuity of C visual acuity table was smaller than that of E visual acuity table. Conclusion: The visual acuity of myopic patients tested by C visual acuity chart is better than by E visual acuity chart. The main reason for the difference between C visual chart and E visual chart was the different shape and opening direction of visual icons.

Methods: Eye disinfection supply center is built with quality management traceability system of real-time collection, department to sign for function module,counting supply room staff use personal digital assistants (PDAs) and clinical departments personnel under the face-to-face equipment recycling counted and send goods receipt, counting of implementation process control,reducing disputes. Results: By using PDA to collect and count the ophthalmic instruments in real time and sign for the receipt of the articles, the accuracy of the recovery and delivery of the articles was improved, the disputes between the supply room and the clinical department caused by the difference in the quantity of the recovered and delivery of the articles were solved, and the paperless management was realized. Conclusion: The module realizes paperless office and improves work efficiency. It reduces the disputes with the clinical departments and improves the satisfaction of the clinical departments with the supply department.
Objective: To observe the efficacy of trehalose eye drops on experimental dry eye rat with removal of inside and outside lacrimal glands. Methods: A total of 30 SD rats were randomly divided into a normal group, a control group, and an experimental group, with 10 rats for each group (20 eyes). The normal group was not treated, and the experimental group and the control group were made into a dry eye animal model by removing the main lacrimal gland of the rat. The control group and the experimental group were given with normal saline and trehalose eye drops once a week after the completion of modeling, 4 times a day for 4 weeks. Shirmer I test and fluorescence staining test were carded before and 1, 2, 3, and 5 weeks after modeling. After 5 weeks of modeling, the rats were sacrificed and the expression of Bcl-2 and Bax apoptosis protein in conjunctival epithelial cells was detected by immunohistochemistry in order to observe the relationship between apoptosis of conjunctival epithelial cells and dry eye lesions and tissue damage in dry eye animal models. Results: Schirme I test results showed that there was no significant difference between the control group and the experimental group (P>0.05) except for the 5th week after operation (P<0.05). There was a statistical difference between the two groups and the normal group at each time point after surgery (P<0.05). At the first week after modeling, the corneal fluorescence staining scores of the control group and the experimental group were significantly higher than those of the normal group. After the second week after surgery, there was no significant difference between the control group and the experimental group (P>0.05). The prolongation of time, the 3 week and the 5th week after surgery, the difference between the two groups was statistically significant (P<0.05), and the score of the experimental group was smaller than the control group. The immunohistochemical results of conjunctival epithelial cells showed that the number of Bax protein positive cells in the normal conjunctival epithelial cells was less than that in the control group and the experimental group. The difference between the normal group and the control group was statistically significant(P<0.05). There was no significant difference between the two groups (P>0.05). There was a large amount of Bcl- 2 protein in the normal group, which was more than the experimental group. The difference was not statistically significant (P>0.05), which was more than the control group. The difference was statistically significant (P<0.05); a large amount of Bax protein was positively expressed in the cytoplasm and brownish-yellow particles in the conjunctival epithelial cells of the control group. The positive expression of Bax protein in the experimental group was significantly less than that in the control group, and the difference was statistically significant (P<0.05). A large amount of Bcl-2 protein was positively expressed in the conjunctival epithelial cells of the experimental group, and the expression of Bcl-2 protein in the control group was significantly decreased compared with the experimental group (P<0.05).Conclusion: Trehalose eye drops can reduce epithelial detachment of the cornea and have a protective effect on conjunctival epithelial cells, which can antagonize the apoptosis of conjunctival epithelial cells,thereby enhancing the keratoconjunctival barrier function and improving the ocular surface epithelium caused by dryness. The potential clinical application of trehalose solution for ocular surface epithelial diseases and provide treatment options for ocular surface diseases, such as dry eye.
Objective: To investigate the change and influencing factors of the effective lens position after cataract surgery in high myopia eyes. Methods: We collected 27 eyes of 21 patients with high myopia who underwent phacoemulsification and intraocular lens implantation. The visual acuity, diopter and effective lens position were recorded 1 day, 1 week, and 1 month after operation. Results: The effective lens position of high myopia combined with cataract patients at 1 day, 1 week, and 1 month was (4.17±0.39), (4.09±0.38), and (4.31±0.44)mm, respectively. The effective lens positions significantly differed between the groups after surgery (P<0.05). The ELPRMS was (0.19±0.13) mm. The ELPRMS was positively correlated with the lens thickness (r=0.648,P<0.001), whereas was not correlated with the preoperative axial length (r=0.227, P=0.255). Conclusion: High myopic patients with cataract have a slight forward movement of the effective lens position from 1 day to 1 week after surgery, and a hyperopic shift from 1 week to 1 month. The displacement of effective lens position after surgery is correlated with the preoperative lens thickness.
Rhegmatogenous retinal detachment is not commonly observed in the adolescent population. Compared to adults, adolescents have a complex and diverse etiology and retinal manifestations for RRD, which often leads to delayed diagnosis due to difficulty in describing symptoms in a timely manner, thus increasing the difficulty of diagnosis and treatment. This article reports a case of familial exudative vitreoretinopathy(FEVR) combined with RRD and outlines the diagnostic approach for myopic retinal detachment in adolescents, aiming to provide clinical reference for ophthalmologists.
