Objective: To retrieve and analyze adverse drug reactions (ADRs) of cyclopentolate hydrochloride eye drops on the US Food and drug Administration Public Data Open Project (OpenFDA), so as to provide reference for clinical rational drug use. Methods: Using "Cyclopentolate hydrochloride eye drops" as the search term, retrieve all information related to ADRs of cyclopentolate hydrochloride eye drops from the OpenFDA database from January 1, 2004 to August 1, 2024, and analyze the retrieved data  Results: A total of 1 185 cases of ADRs associated with cyclopentolate hydrochloride eye drops were found. Among the 1185 patients, 516 were female and 483 were male ( 43.54 % vs 40.76 % ) after excluding the unknown gender. After excluding patients with unknown age, the incidence of ADRs was higher in patients aged 65~ < 80 years old ( 221 cases, 18.65 % ), 50~< 65 years old ( 176 cases, 14.85 % ), and 3~ < 13 years old ( 140 cases, 11.81 % ). The ADRs with high incidence of cyclopentolate hydrochloride eye drops were ocular organ diseases ( 767 cases, 64.73 % ), nervous system diseases ( 254 cases, 21.43 % ) and gastrointestinal system diseases ( 228 cases, 19.24 % ). Conclusions: Cyclopentolate hydrochloride eye drops can cause local and systemic adverse reactions. In clinical use, the patient 's disease history and medication history should be asked in detail, and medication monitoring should be strengthened to improve the safety of patient medication.

Purpose: The surgical risk and complication rate after cataract surgery are extremely high in patients with nanophthalmos. This study is designed to compare the visual and refractive outcomes before and after coaxial micro-incision phacoemulsification and evaluate postoperative complications．

Methods: Fifty nine patients (89 eyes) with axial length (AL)＜21 mm diagnosed with nanophthalmos were enrolled in this retrospective study. All patients underwent coaxial micro-incision phacoemulsification and IOL implantation. The main outcome measures included anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), intraocular pressure (IOP) and best corrected visual acuity (BCVA). Wilcoxon signed rank test or Mann-Whitney test, and Chi-square test and logistic regression analysis were performed for statistical tests as appropriate．

Results: The median AL was 19．63 mm. Sixty-six eyes (74.16％) had a history of surgical intervention. Postoperative ACD, ACV and ACA were increased significantly (all P＜0.001), whereas postoperative IOP was decreased significantly. (P＜ 0.001) after surgery. Previous surgical intervention was related to a reduction in the postoperative ACD and ACA (P＜0.01), and both preoperative and postoperative IOP (P＜0.001). Postoperative BCVA was improved in 94．38％ of the cases. Intraoperative complications mainly included iridoschisis (6 eyes, 6.74％). Early postoperative complications included temporary corneal edema (TCE) (23 eyes, 25.84％), anterior inflammatory response (AIR) (19 eyes, 21.35％), cystoid macular edema (CME) (14 eyes, 15.73％), and uveal effusion (4 eyes, 4.49％). Late postoperative complications included CME (8 eyes, 8.99％),  uveal effusion (8 eyes, 8.99％), malignant glaucoma (2 eyes, 2.25％) and posterior capsular opacification (PCO)(10 eyes, 11.24％). The majority of complications (80％) were successfully resolved by pharmacotherapy or operation. The risk of surgical complications was greater in patients with lower AL, ACD, ACV or ACA and higher nuclear hardness or mean keratometry (Km).

Conclusion: With reasonable preoperative management, prudent selection of the lens, rigorous surgical technique and unerring cognition of potential complications, coaxial microincision phacoemulsification lens surgery can be performed in patients with nanophthalmos and yield favorable outcomes and a low incidence of complications.

原发性干燥综合征 (primary Sjogren' s syndrome，SS) 是一种主要累及外分泌腺体的自身免疫性疾病，患者通常因为严重的干眼症状首先就诊于眼科，大多数临床医师对原发性干燥综合征相关性干眼 (Sjogren' s syndrome dry eye disease，SS-DED) 认识不足，可能导致漏诊和误诊。侵入性极小的客观检查及生物标志物的发展，将有助于发现 SS-DED 的真面目，并可能从新的角度阐释其发病机制，为其诊断、分类及治疗提供新的思路。SS-DED 的治疗没有特效的药物，大多数患者需接受多种方法的治疗，以了解哪些方法最有效。

Primary Sjogren' 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 Sjogren' s syndrome probably leading to misdiagnosis or missing the diagnosis. The diagnosis of Sjogren' 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. 

目的：评价海藻糖滴眼液对摘除眶内眶外泪腺的实验性大鼠干眼的疗效。方法：SD 大鼠 30 只，随机分成正常组、对照组、实验组，每组 10 只（20 只眼）。正常组不给予处置，实验组和对照组通过摘除大鼠主泪腺制作干眼动物模型。对照组和实验组于造模完成术后 1 周后分别给予生理盐水、海藻糖滴眼液点双眼，每天 4 次，治疗共 4 周。分别于造模术前和造模术后 1、2、3、5 周进行基础泪液分泌试验（Shirmer I test），角膜上皮荧光染色评分检测；造模 5 周后将大鼠处死，采用免疫组织化学方法对结膜上皮细胞中 Bcl-2 和 Bax 凋亡基因蛋白表达进行检测，观察干眼动物模型结膜上皮细胞凋亡与眼表干眼病变及组织损伤的关系。结果：基础泪液分泌试验结果显示，对照组和实验组除术后第 5 周比较差异有统计学意义外（P < 0.05），其余时间点差异无统计学意义（P > 0.05），术后各时间点与正常组比较差异均有统计学意义（P < 0.05）。造模术后第 1 周，对照组和实验组角膜荧光染色评分明显高于正常组；术后第 2 周后，对照组和实验组评分差异无统计学意义（P > 0.05），随着时间的延长，术后第 3 周和第 5 周，两组评分差异均有统计学意义（P < 0.05），且实验组评分小于对照组。结膜上皮细胞免疫组织化学检测结果显示：正常组结膜上皮细胞 Bax 蛋白阳性表达的细胞数较对照组和实验组少，与对照组比较，差异有统计学意义（P < 0.05），与实验组比较差异无统计学意义（P > 0.05）；正常组可见大量 Bcl-2 蛋白阳性表达，且多于实验组，差异无统计学意义（P > 0.05），多于对照组，差异有统计学意义（P < 0.05）；对照组结膜上皮细胞中可见大量 Bax 蛋白阳性表达于细胞质，呈棕黄色颗粒，实验组中 Bax 蛋白阳性表达相对于对照组明显较少，两者差异有统计学意义（P < 0.05）；实验组结膜上皮细胞中可见大量 Bcl-2 蛋白阳性表达，对照组 Bcl-2 蛋白表达相对于实验组明显减少，差异有统计学意义（P < 0.05）。结论：海藻糖滴眼液可以减少角膜表层上皮脱落，对结膜上皮细胞有一定的保护作用，可以拮抗结膜上皮细胞的凋亡，从而增强角结膜上皮屏障功能，改善由干燥引起的眼表上皮的损伤。海藻糖溶液可用于眼表上皮疾病的潜在临床应用，为治疗眼表疾病如干眼症提供治疗选择。

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 bydryness. The potential clinical application of trehalose solution for ocular surface epithelial diseases and provide treatment options for ocular surface diseases, such as dry eye.
