年龄相关性黄斑变性(age-related macular degeneration,AMD)是一种发生在黄斑区的退行性变,其中湿性年龄相关性黄斑变性(wet age-related macular degeneration,wAMD)以黄斑区新生血管为主要病理特征,是导致老年人视力受损甚至失明的重要原因,视网膜下纤维化是wAMD最常见的自然后遗症,可导致光感受器、视网膜色素上皮(retinal pigment epithelial,RPE)和脉络膜毛细血管受损,导致不可逆转的中心视力丧失。多种基线特征被发现是视网膜下纤维化的危险因素,可用于预测早期视网膜下纤维化的发生。迄今为止,还没有有效的抗纤维化治疗方法,抗血管内皮生长因子(anti-vascular endothelia growth factor, anti-VEGF)治疗是wAMD的一线治疗方案,该治疗方法不能改善视网膜下纤维化,但及时启动治疗可能有助于预防或延缓纤维化的进展,目前多种靶向分子药物正被研发用于抗纤维化的治疗。该文综述了wAMD视网膜下纤维化的临床表现及意义、预测纤维化形成的基线特征、基本发病机制及潜在的抗纤维化治疗方法,旨在为临床诊治工作提供参考。
Age-related macular degeneration (AMD) is a degenerative disease of the macular, and wet age-related macular degeneration(wAMD) is mainly characterized by macular neovascularization, which is an important reason of visual impairment or even blindness in the elderly. Subretinal fibrosis is the most common natural sequelae of wAMD, which can lead to irreversible central vision loss by damaging photoreceptors, RPE, and choroidal capillaries. Multiple baseline features have been identified as the risk factors for subretinal fibrosis, which can be used to predict the early subretinal fibrosis. Heretofore, no anti fibrotic treatment method is effective. Anti vascular endothelial growth factor (anti VEGF) treatment is the first-line treatment for wAMD. This therapy cannot improve subretinal fibrosis, but timely initiation of treatment may help prevent or delay the progression of fibrosis. Currently, multiple targeted molecular drugs are being developed for anti fibrotic treatment. This article reviews the clinical manifestations and significance of subretinal fibrosis in wet age-related macular degeneration, baseline features for predicting the formation of fibrosis, basic pathogenesis, and potential anti-fibrosis treatment methods,aiming to provide reference for clinical diagnosis and treatment.

A 60-year-old woman was admitted to Chengdu Aidi Eye Hospital because of “dark shadow fluttering in the right eye for 1 month and vision loss for 8 days”. Visual acuity—with a myopic correction—was 0.1 with the right eye and 0.9 with the left eye. The right eye fundus presented a well-defined, irregular, grayish white area around the optic disc, and affected the fovea, corresponding to the visual field defect of the fundus lesion. Optical coherence tomography (OCT) showed that the ellipsoid bands in this region were irregular and absent, and several finger-like ridges were seen in the retinal pigment epithelium (RPE) layer. Fundus autofluorescence (AF): High fluorescence and some irregular low fluorescence in the affected area. Fundus fluorescein angiography (FFA): Fluorescence leakage was seen in the early stage, fluorescence staining and accumulation in the late stage. Indocyanine green angiography (ICGA): A well-defined low-fluorescence area centered on the optic nipple was observed. Diagnosis:Acute annular outer retinopathy. Treatment: Anti-inflammatory and improved blood circulation for 4 weeks, the gray and white ring of fundus disappeared and the visual acuity improved obviously

Objective: To investigate the predictive accuracy andeffect of capsular tension ring (CTR) implantation with fivenew generation intraocular lens (IOL) calculation formulas [Barrett Universal Ⅱ (BU Ⅱ ), Emmetropia VerifyingOptical (EVO), Kane, Pearl-DGS and Hill-RBF 2.0] in high myopia patients. Methods: This is a prospectivecase-control study. The patients were enrolled with an axial length (AL)≥27.00 mm, and underwent cataract surgery with AR40E IOL implantation at the Shaanxi Eye Hospital from December 2020 to September 2021. Thepatients were randomly assigned to the CTR implantation group (group A) and the non-CTR implantation group(group B). With the ocular parameters measured by the IOL-Master 700, the IOL power was calculated with theBU Ⅱ formula before surgery. The postoperative actual equivalent spherical diopter (SE) were recorded,and the predicted error (PE) and absolute error (AE) using the five formulas were recorded and compared at 1 week, 1 month, and 3 months, repsectively. Group A was divided to A1 (27.00 mm ≤ AL ≤ 30.00 mm) and A2 (AL>30.00 mm), and group B was divided to B1 (27.00 mm ≤ AL ≤ 30.00 mm) and B2 (AL>30.00 mm). The effects of CTR implantation and the accuracy of the formulaswere analyzed with different AL ranges. Results: A total of 63 patients (89 eyes) were included, aged (55.93±10.17) years old, with preoperative AL (30.30± 2.18) mm. There was no statistically significant difference in SE between groups A, A1, and A2 (P>0.05) at different postoperative times. While there was a statistically significant difference in SE between groups B, B1, and B2 (P < 0.05) at 1 week and 1 month after surgery, and between 1 week and 3 months after surgery. There was no statistically significant difference between 1 month and 3 months after suergery (P>0.05). There was no significant difference in the AE using the five formulas among groups A, B, A1, A2, B1, and B2 (H= 9.27, P= 0.06, H= 7.09, P= 0.13, H= 2.44, P= 0.66,H= 8.56, P= 0.07, H= 4.16, P= 0.39, H= 8.72, P= 0.07). There was no statistically significant difference in prediction error changes among the five formulas after CTR implantation (P>0.05). Conclusion: For cataract patients with AL ≥27.00 mm, the refractionvalue in the CTR implantation group tended to stabilizeafter one week of surgery. While in the non-CTR implantation group, the refractionvalue tended to stabilize after one month. CTR implantation had no effect on the accuracy and selection of the five formula, and the five IOL calculation formulas can be normally selected.

青光眼是全球第二大致盲眼病,第一大不可逆性致盲眼病,其中原发性闭角型青光眼(primary angle closure glaucoma,PACG)占25%。激光周边虹膜切除术(laser peripheral iridotomy,LPI)已成为PACG和原发性房角关闭的一线治疗。LPI机制为利用激光在周边虹膜上打孔,解除PACG的瞳孔阻滞,加深前房,扩大房角,恢复生理性房水排出途径,从而降低眼压。研究表明LPI在原发性房角关闭各个疾病进程中均能比较好的控制眼压,是相对安全的治疗方法。
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.
