目的 探讨增生期糖尿病视网膜病变患者经全视网膜激光光凝治疗的临床效果。方法 选取2016年2月—2019年3月我院收治的增生期糖尿病视网膜病变患者97例,使用随机数表法分为观察组(49例)与对照组(48例)。对照组患者接受黄斑格栅样光凝治疗,观察组患者则接受全视网膜激光光凝治疗。收集2组患者手术前后视力、黄斑中心凹容积、乳头周边视网膜神经纤维层厚度及视网膜厚度变化情况等数据进行分析,并对比生活质量评分。结果 治疗前,2组患者视乳头旁视网膜神经纤维层厚度、黄斑中心凹容积以及视网膜厚度之间差异无统计学意义(P＞0.05),具有可比性。接受不同治疗后,观察组患者上述3项指标均优于对照组患者(P＜0.05)。观察组患者治疗总有效率为79.59%,高于对照组患者治疗总有效率59.18%(P＜0.05)。此外,观察组患者在精细动作、调节能力、日常生活及远视力、光感和移动4个维度评分均高于对照组患者(P＜0.05)。结论 与黄斑格栅样光凝治疗相比,增生期糖尿病视网膜病变患者接受全视网膜激光光凝治疗有助于改善其乳头周边视网膜神经纤维层厚度和黄斑区视网膜厚度,能够显著促进视力恢复,提升患者生活质量,疗效确切。

Objective To investigate the clinical effect of panretinal laser photocoagulation for proliferative diabetic retinopathy. Methods 97 cases of proliferative diabetic retinopathy in our hospital from Feb 2016 to Mar 2019 were enrolled in the study, and were divided into 2 groups randomly. The control group received treatment of macular grid photocoagulation, while the observation group received whole retina laser photocoagulation. Data of visual acuity, macular fovea volume, retinal nerve fiber layer thickness around nipple and retinal thickness before and after operation were collected and analyzed, and quality of life scores were compared. Results Before treatment, there was no significant difference in retinal nerve fiber layer thickness, macular fovea volume and retinal thickness between the two groups (P>0.05), which was comparable. After different treatments, the three indexes mentioned above in the observation group were better than those in the control group (P<0.05). The total effective rate of the observation group was 79.59%, which was higher than that of the control group (59.18%, P<0.05). In addition, the scores of fine motion, accommodation ability, daily life and distant vision, light perception and movement in the observation group were higher than those in the control group (P<0.05). Conclusion Compared with macular grid-like photocoagulation, panretinal laser photocoagulation may improve the retinal nerve fiber layer thickness around the nipple and macular retinal thickness in patients with proliferative diabetic retinopathy. It promotes the recovery of visual acuity, improves the quality of life of patients, and has definite curative effect.

Objective To observe the effect on the thickness of retinal nerve fibers in the patients with wet age-related macular degeneration by adopted intravitreal injection with Conbercept. Methods We analyzed 18 cases （18 eyes） that conform to the standard from 35 cases（38 eyes） retrospectively,who were treated with wet age-related macular degeneration by adopted intravitreal injection with Conbercept in Shaoguan Yuebei People's Hospital Affiliated to Shantou University from October in 2016 to October in 2017.After undergoing best corrected visual acuity （BCVA）,intraocular pressure （IOP） and fluorescein angiography （FFA）,all of them were adopted intravitreal injection with 0.05mL Conbercept. We observed the changes of best corrected visual acuity （BCVA） and retinal nerve fiber thickness （RNFL） after 1 and 2 months of adopted intravitreal injection with 0.05 mL Conbercept. Results 18 eyes were adopted intravitreal injection Conbercept 54 times totally. All the eyes were injected three times. After 3 months of injection,OCT showed that the visual acuity of 18 eyes improved and the thickness of CRT decreased. The BCVA values at the first injection,after the first injection and after the second injection were 0.1（0.04,0.12）,0.20（0.10,0.30）和0.25（0.12,0.30）respectively. The overall difference was statistically significant （χ²=13.880,P< 0.001）. CRT（μm）values at the first injection,after the first injection and after the second injection were 319.50（269.50,390.50）,271.00（219.00,296.25） and 234.50（182.75,273.25）respectively. The overall difference was statistically significant （χ²=11.978,P< 0.05）. ARNFL（μm）values at the first injection,after the first injection and after the second injection were 86.00（76.25,98.00）,83.00（76.00,95.50） and 83.00（76.25,94.75）respectively. There was no significant difference （χ²=11.978,P> 0.05）. The IOP（mmHg）values at the first injection,after the first injection and after the second injection were 17.0（14.8,18.3）,16.0（13.7,17.0）,和 15.0（13.8,17.3）respectively. There was no significant difference（χ²=1.604,P>0.05）. Conclusion There was no obvious damage to the retinal nerve fiber by adopted intravitreal injection with Conbercept to treat the patients with wet age-related macular degeneration. That’s safe and effective,but need a large sample to follow-up for a longtime.

Objective To observe the protective effects of Puerarin on apoptosis of ischemic injury in rabbit retina. Methods Retinal ischemia was induced in rabbits by increasing intraocular pressure to 120 mmHg for 60 minutes. TdT-mediated biotin-dUTP nick end labelling(TUNEL) staining technique was used to examine the apoptosis of retinal ganglion cells in the control group and the puerarin treatment group. Results The number of apoptotic cells in 12, 24 and 72h after reperfusion in the puerarin treatment group was obvious lower than that in the control group(P<0.05). Conclusion Puerarin has protective effects in protecting against apoptosis in ischemia reperfusion injury of rabbit retina.
