目的：评估硅油填充术后眼压对角膜内皮细胞的影响及变化特点。方法：选取2019年1月1日至9月30日在佛山市第二人民医院眼科中心行玻璃体切除联合硅油注射的患者共131名，分为高眼压组(n=80)和正常眼压组(n=51)。高眼压组术后任意一次测眼压>21 mmHg，正常眼压组术后眼压均≤21 mmHg。比较填充硅油前与取硅油时的角膜内皮细胞参数测量值。结果：高眼压组的平均眼压为20.79 mmHg，正常眼压组的平均眼压为14.70 mmHg(P<0.001)。取硅油时，两组角膜内皮细胞密度(corneal endothelial cell density，ECD)均明显减少，平均内皮细胞面积均明显增大(P<0.05)，高眼压组内皮细胞大小变异系数(coefficient of variation of endothelial cell size，CV)明显变大(P<0.05)。高眼压组ECD丢失率(6.3%)高于正常眼压组(3.5%)；其中，高眼压组中术后1~6周内的眼压升高(7.1%)、眼压≥40 mmHg(7.3%)对角膜内皮细胞影响最大。ECD丢失与眼压变化有显著相关性(r=0.176，P=0.044)。结论：硅油填充后高眼压是角膜内皮细胞丢失的重要危险因素。

Objective: To evaluate the effect of intraocular pressure (IOP) on corneal endothelial cells after silicone oil tamponade. Methods: Patients (n=131) received vitrectomy with silicone oil injection in Ophthalmology Center in Second People’s Hospital of Foshan City from January 1st to September 30th 2019 were divided into the high IOP group (n=80) and normal IOP group (n=51). IOP was >21 mmHg at any time in the high IOP group and was ≤21mmHg in the normal IOP group after surgery. The values of corneal endothelial cells before filling with silicone oil and before removing silicone oil were compared.Results: The average IOP was 20.79 mmHg in the high IOP group, and 14.70 mmHg in the normal IOP group (P<0.001). The number of endothelial cells (ECD) was reduced, but the average endothelial cell area was increased (P<0.05) in both groups. The coefficient of variation of endothelial cell size in high IOP group was increased (P<0.05). ECD loss rate was 6.3% in the high IOP group and 3.5% in normal IOP group. Increased IOP within 1–6 weeks after surgery (7.1%) and IOP ≥40 mmHg (7.3%) had the greatest impact on ECD. ECD loss was correlated with IOP (r=0.176, P=0.044). Conclusion: High intraocular pressure after silicone oil filling is an important risk factor for the loss of corneal endothelial cells.Keywords intraocular pressure; corneal endothelium; silicone oil; vitrect

目的：探究球面塑形镜、环曲面塑形镜在矫治近视复合散光的有效性及安全性。方法：回顾分析宜昌市第一人民医院2016年3月至2018年3月角膜塑形镜治疗青少年近视94例(178眼)，按佩戴塑形镜类型分为球面塑形镜组(48例，90眼)与环曲面塑形镜组(46例，88眼)。记录配镜前、佩戴1年后、停戴1周后的视力、角膜散光、眼轴长、球镜屈光度、眼压、泪膜破裂时间及角膜着染率。结果：戴镜1年后，2组组内相比，散光、球镜度数、眼压、泪膜破裂时间均降低，但2组组间相比，仅散光度数差异有统计学意义(P<0.01)。戴镜1年后，两组视力较戴镜前显著提高，停戴后近视度数较佩戴前增加，但组间差异无统计学意义(P>0.05)；2种塑形镜角膜着染发生率差异无统计学意义(P>0.05)。结论：2种塑形镜均能够降低近视复合散光患者度数，有效提高患者视力，但并不能完全阻止近视的进展。虽然环曲面塑形镜在矫正散光方面有优势，但总有效性与安全性并不占优势。

Objective: To observe the effectiveness and safety of orthokeratology lens and toric design othokeratology treatment for compound myopic astigmatism. Methods: From March 2016 to March 2018, 94 teenagers(178 eyes) were selected as the subjects of study. They were divided into two groups according to the type of orthokeratology: the orthokeratology lens group (48 cases, 90 eyes) and the toric design othokeratology group(46 cases, 88 eyes). Visual acuity, corneal astigmatism, axial length, spherical lens refraction, intraocular pressure,tear film rupture time and corneal staining rate were recorded before, after 1 year and after 1 week. Results: After 1 year of wearing the lens, astigmatism, spherical lens degree, intraocular pressure and tear film rupture time were all decreased in the 2 groups compared with each other, but only astigmatism degree was statistically significant between the 2 groups compared with each other (P<0.01). After wearing the glasses for 1 year, the visual acuity of the two groups was significantly improved compared with that before wearing the glasses, and the myopia degree was increased after stopping wearing the glasses compared with that before wearing the glasses, but the difference between the two groups was not statistically significant (P>0.05). There was no statistical significance in the incidence of corneal staining between the two types of shaping lenses (P>0.05). Conclusion: Both of the two shaping lenses can reduce the degree of myopic patients with complex astigmatism and effectively improve the visual acuity of patients, but they can not completely prevent the progress of myopia. Although toroidal shaping mirror has advantages in correcting astigmatism, its overall effectiveness and safety are not.

Objective: To compare the consistency of Kappa Angle measurements in patients with age-related cataracts using four instruments of different principles in a dark room. Methods: Sixty cases (60 eyes) of age-related cataract were adapted in the darkroom for 10 minutes. The pupil size and angle Kappa were measured by iTrace, Pentacam HR, Lenstar900 and IOLMaster700. One-way ANOVA test and Kruskal-Wallis nonparametric test were used to compare the measured data among the four instruments, and Bland-Altman analysis was used for consistency comparison. Results: The measured pupil diameters of iTrace, Pentacam HR, Lenstar900 and IOLmaster700 were 4.64±0.71 mm, 2.96±0.47 mm, 4.86±0.76 mm and 4.66±0.92 mm. The Angle Kappa sizes were 0.227±0.121 mm, 0.161± 0.09 mm, 0.2±0.124 mm, 0.203±0.104 mm. The proportion of angle Kappa larger than 0.5 mm was 3.33%, 3.33%, 1.67% and 1.67%. The measurement results of angle Kappa between Pentacam and iTrace were statistically significant (P=0.001). There was no significant difference in the measurement results of angle Kappa between Pentacam and Lenstar900, Pentacam HR and IOL-Master700 (P=0.044, 0.036). There was no significant difference in the results of angle Kappa measurement among the other three instruments. The subjective score of light intensity in the process of measurement of iTrace, Pentacam HR, Lenstar900 and IOLMaster700 showed that during the process of measurement, 60 cases (100%) experienced obvious discomfort caused by the light intensity in Pentacam HR, while 40 cases (66.67%) felt comfort in IOLMaster700. The differences among the subjective score of light intensity of four instruments were statistically significant (P<0.001). Conclusion: The consistency of the measurement results of Kappa angle between Pentacam HR and iTrace, Lenstar900, IOLMaster700 in the darkroom is relatively poor, so it is necessary to be careful to replace them in clinic.
