目的：在硅油取出联合白内障手术患者中，使用扫频源光学相干断层扫描生物测量仪OA-2000进行生物测量，比较10种人工晶状体(IOL)屈光力计算公式的准确性。方法：回顾性分析2021年3月—7月于中山大学中山眼科中心接受硅油取出联合白内障手术的患者共62例(62眼)，所有患者均使用扫频源光学相干断层扫描生物测量仪OA-2000进行生物学参数测量。计算并比较新公式[Barrett Universal II (BUII)、Emmetropia Verifying Optical(EVO) 2.0、Hill-Radial Basis Function (Hill-RBF) 3.0、Hoffer QST、Kane、Pearl-DGS]及传统公式(Haigis、Hoffer Q、Holladay 1、SRK/T)的预测准确性，主要评价指标为绝对预测误差中位数(MedAE)及平均绝对预测误差(MAE)。按眼轴长度≤23 mm(组1)，>23 mm且≤26 mm(组2)与>26 mm(组3)进行亚组分析。结果：6个新公式、Haigis、SRK/T公式均出现近视漂移(-0.47 ~-0.27 D，P<0.05)，而HofferQ及Holladay 1公式无系统误差(P>0.05)。Kane公式的MedAE(0.55 D)及MAE(0.81 D)最小，但公式间比较差异无统计学意义(P>0.05)。组1中所有公式均出现近视漂移(-1.46~ -1.25 D，P<0.05)，而其他亚组比较差异无统计学意义(-0.32 ~ 0.41 D，P>0.05)。在组1中，Pearl-DGS公式的MedAE(0.97 D)及MAE(1.26 D)最小，且优于Hill-RBF 3.0(P=0.01)及SRK/T公式(P=0.02)；组2中，Kane公式具有最小的MedAE(0.44 D)及MAE(0.66 D)；组3各个公式屈光预测准确性比较差异无统计学意义(P>0.05)。结论：在使用OA-2000进行术前生物测量时，Kane公式在接受硅油取出联合白内障手术患者中的预测准确性较高；而眼轴长度≤23 mm时，Pearl-DGS公式可能更为准确。

Objective: To compare the accuracy of 10 intraocular lens (IOL) power calculation formulas in patients undergoing combined silicone oil removal and cataract surgery, biometry is performed using the swept-source optical coherence tomography biometer OA-2000. Methods: A retrospective analysis. A total of 62 patients (62 eyes) who underwent combined silicone oil removal and cataract surgery in Zhongshan Ophthalmic Center, Sun Yat-sen University from March to July in 2021 were enrolled. Preoperative biometry was performed by OA-2000 in all patients. New-generation formulas (Barrett Universal II [BUII], Emmetropia Verifying Optical [EVO] 2.0, Hill-Radial Basis Function [Hill-RBF] 3.0, Hoffer QST, Kane and Pearl-DGS) and traditional formulas (Haigis, Hoffer Q, Holladay 1 and SRK/T) were evaluated. The median absolute prediction error (MedAE) and mean absolute prediction error (MAE) were the main parameters used to assess accuracy. Subgroup analyses were performed based on the axial length of 23 mm and 26 mm. Results: Six new-generation formulas, Haigis, and SRK/T showed myopic shift (-0.47 ~ -0.27 D, P<0.05), while no systematic bias was found in Hoffer Q and Holladay 1 displayed (P>0.05). The smallest MedAE (0.55 D) and MAE (0.81 D) were found in Kane formula, but there was no statistically significant difference compared with other formulas (P>0.05). The myopic shift (-1.46 ~ -1.25 D, P<0.05) in eyes shorter than 23 mm were found in all formulas, while there was no significant systematic bias (-0.32 ~ 0.41 D, P>0.05) in other subgroups. In axial length shorter than 23 mm, the Pearl-DGS formula stated the smallest MedAE (0.97 D) and MAE (1.26 D), and was significantly more accurate than Hill-RBF 3.0 (P=0.01) and SRK/T (P=0.02). In eyes with an axial length between 23 mm and 26 mm, the Kane formula had the lowest MedAE (0.44 D) and MAE (0.66 D). No significant difference was found in eyes longer than 26 mm. Conclusion: The Kane formula showed the highest accuracy in patients undergoing combined silicone oil removal and cataract surgery measured by OA-2000, whereas the Pearl-DGS formula could be more accurate in eyes with an axial length shorter than 23 mm.

Methods: The quality of life questionnaire of thyroid associated ophthalmopathy was used to investigate, and the data were analyzed by R language. Results: There was a negative correlation between age and visual function score (P<0.001, r=-0.504), and positively correlated with social psychological score (P=0.002, r=0.327). There was a positive correlation between educational level and visual function score (P<0.001, r=0.391), and had no correlation with social psychological score (P=0.749). There were statistically significant differences in visual function scores among different symptoms (P<0.001).Conclusion: The quality of life of thyroid-related eye disease questionnaire showed that the older, the worse the visual function. Different symptoms of patients had different visual function. We should pay attention to the patients with older, diplopia and poor vision, do health education with the patients and family members with the history of hyperthyroidism as well, especially concern with the social and psychological status of female patients.

Objective: To understand the infection status of four blood-borne pathogens among ophthalmology patients in South China and the distribution of positive patients across different eye diseases. Methods: A retrospective analysis of data from outpatient and inpatient or surgical ophthalmic patients who underwent screening for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (anti-HCV), treponema pallidum antibody (anti-TP) and human immunodeficiency virus antibody (anti-HIV) at Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2017 to December 2023. The positivity rates of these markers were recorded and analyzed. Results: A total of 253246 patients were included in the study, with positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV at 9.00%, 0.45%, 1.55% and 0.13%, respectively. Among these, 686 patients tested positive for two or more markers, with the highest co-positivity observed for HBsAg and anti-HCV (57.29%), followed by anti-HIV and anti-TP (15.74%). The positivity rate of HBsAg showed a yearly decline, while the rates for anti-HCV, anti-HIV, and anti-TP remained relatively stable from 2017 to 2023. Males had significantly higher positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV compared to females (P < 0.001). Significant differences in positivity rates for these markers were also observed across different age groups (P < 0.001). In patients with positive HBsAg, anti-HCV, and anti-TP, the proportion of cases with lens diseases were the highest, at 36.72%, 39.12%, and 46.97%, respectively. Vitreoretinal diseases followed, with proportions of 22.52%, 19.65%, and 19.69%, respectively. Among patients with positive anti-HIV, the proportion of cases with vitreoretinal diseases was the highest, at 42.99%, followed by lens diseases at 26.17%, and uveitis at 8.72%. Conclusions: This study reveals the infection status of four blood-borne pathogens in ophthalmology patients and the distribution of infected patients across different eye diseases, which is significant for assessing the risks of ophthalmic surgery and formulating infection control measures.

Purpose: To observe the changes of macular thickness in patients with sleep apnea syndrome (SAS) before and after sleep.

Methods: Thirty-two patients (63 eyes) diagnosed as SAS from August 2003 to January 2007 were enrolled. Macular thickness was measured using Optical Coherence Tomography (OCT) at 11:00 ~ 12:00 evening (before sleep) and 20 ~ 30 minutes after sleep, respectively.

Results: The mean macular thickness was (123.00 ± 19.98) μm and (134.25 ± 19.92) μm before and after sleep, respectively. The mean difference was (11.25 ± 9.04) μm before and after sleep (t = 9.878, P < 0.05), 95% CI (8.98, 13.53) μm.

Conclusions: The macular thickness of SAS is increased in SAS patients, which may be due to anoxia of SAS.
