Most ophthalmic surgeries are characterized by small incisions and mild pain, therein, the choice of topical anesthesia can meet the needs of surgeries and accelerate ophthalmic surgeries to be conducted in day surgery model. 0.4% oxybuprocaine hydrochloride eye drops is one of commonly used topical anesthetics for ophthalmic surgery, which has the characteristics of rapid onset and sufficient analgesia with long duration (about 13 minutes). Oxybuprocaine hydrochloride eye drops has been widely and safely used in intraocular surgery without affecting the pupil and blood vessels. Meanwhile, oxybuprocaine hydrochloride eye drops has negligible effects on corneal thickness and corneal epithelial thickness to meet the needs of refractive surgery. In addition, oxybuprocaine hydrochloride eye drops can provide sufficient postoperative analgesia, reduce the use of postoperative analgesics and the incidence of emergence agitation in children after strabismus surgery. The preservative-free topical anesthetic would be one of ideal topical anesthetics as it can provide a good surgical condition and reduce complications and risks of post-operative infections without changing the onset time and analgesia effects. This article provides a review of the mechanism, analgesia, pharmacokinetics, clinical efficacy, and safety profiles of 0.4% oxybuprocaine hydrochloride eye drops.

青光眼是一组以病理性眼压升高为主要危险因素的，以青光眼性神经萎缩和视野缺损为主要特征的全球首位不可逆性致盲眼病。超声睫状体成形术(UCP)是一种新型非侵入性青光眼治疗技术，其降眼压主要原理为利用高强度聚焦超声破坏睫状突上皮细胞以减少房水生成，并增加葡萄膜巩膜通道的房水流出。UCP适应证广泛，早期主要用于各类难治性青光眼患者，特别是晚期及绝对期患者，研究者发现其除降眼压外，还能够显著缓解该类患者的局部疼痛。近年来，UCP在未经手术治疗的青光眼患者和早、中期青光眼病例中，也表现出了良好的降眼压效果，同时显示出较少的并发症和较轻的术后反应，并可重复治疗。然而不同类型青光眼UCP疗效存在一定差异，且为达最佳治疗效果，其治疗需匹配恰当的探头型号以及适当的治疗扇区。现有较广泛应用于国外的基于眼轴和白到白参数的公式计算方法，测算精度并不适用于国人，然而精准度更高的模型法，其便捷性仍有待进一步提高。UCP虽可减少降眼压药物用量，但术后用药策略的调整仍可能导致眼压波动。综上，针对UCP手术的适应证选择、手术参数设计、疗效预判以及术后管理策略等，仍有待开展相关临床研究，以期为其临床应用提供更加可靠的依据。

目的: 研究 TGF-β1 短期眼部应用对兔角膜碱烧伤后整合素 β1 表达和角膜上皮愈合的影响,探求其对角膜碱烧伤的治疗作用。

方法: 制备大耳白家兔角膜碱烧伤模型, 一组给予 TGF-β1 (浓度为 200 ng /ml) 局部滴眼, 每日 3 次, 连续 7 日; 另一组给予 PBS 溶液代替, 处理相同。于角膜碱烧伤后每日观察角膜上皮愈合面积, 并于烧伤后 6 h、1 d、3 d、7 d 和 14 d 5 个时间点应用免疫组化方法检测 TGF-β1 实验组与 PBS 组角膜整合素 β1 表达情况。

结果: 烧伤后 4 d、10 d、11 d、12 d 和 14 d 实验组和对照组上皮愈合率比较, 差异有统计学意义(P < 0.05) , 两组随着上皮修复过程的进行, 整合素 β1 的表达均逐渐增加, 烧伤后 7 d、14 d两个时间点实验组和对照组整合素 β1 平均灰度值比较, 差异有显著性(P < 0.05) 。

结论: TGF-β1 在活体实验中能促进整合素 β1 的表达, 而后者的增加可以促进角膜上皮细胞向损伤区域的移行和粘附, 从而减少碱烧伤愈合过程中上皮再次脱落现象, 有利于创伤愈合。

Purpose: To observe the effect of TGF-β1 applied topically to the alkali-injured rabbit eye on corneal epithelial wound healing and expression of integrin β1 and its therapeutic action on corneal alkali burns.
Methods: Alkali burn was produced in 60 corneas from 30 rabbits. Two groups were randomly divided. One group was treated with TGF-β1 solution (200 ng /ml) topically 3 times one day within the first 7 days, the other group was treated with phosphate-buffered saline (PBS) solution. The injured eyes were photographed after the fluorescence staining with a digital camera and the pictures were analyzed with computer-aided picture analysis system to calculate the rate of corneal epithelial healing. The expression of integrin β1 was investigated in the point 6 h, 1 d, 3 d, 7 d, 14 d after the injury by means of immunohistochemical analysis.
Results: On the 4th, 10th, 11st, 12nd and 14th days after the burning, the rate of corneal epithelial healing of TGF-β1 groups was markedly higher than that of the PBS group (P < 0.05) . The expression of integrin β1 in the cornea epithelial cells gradually increased during the wound healing. On the 7th and 14th days after the burning, the expression of integrin β1 in the cornea epithelial cells of TGF-β1 group was remarkably  higher than that of the PBS group(P < 0.05) .

Conclusions: TGF-β1 could up-regulate integrin β1 in vivo corneal alkali burn model, which could stimulate the cornea epithelial cells to migrate and adhere to the cornea stroma, that can reduce the cases of the epithelial cells_detachment from the cornea stroma and sustain the corneal reepithelization.
