To evaluate stereopsis after successful surgery for unilateral rhegmatogenous retinal detachment (RD), and to investigate the relationship between stereopsis and clinical factors.
In 75 patients after RD surgery and 28 age-matched normal subjects, stereopsis was measured using the Titmus Stereo Test (TST) and TNO stereotest. Clinical data were collected, including age, gender, circumferential dimension of retinal tears, area and duration of RD, macular status, surgical procedures, postoperative spherical equivalent, and logarithm of the minimum angle of resolution best-corrected visual acuity (logMAR BCVA), low-contrast visual acuity, postoperative lens status (phakia/pseudophakia), and presence of postoperative epiretinal membrane (ERM), to determine the factors related to stereopsis.
Stereopsis in patients after surgery was significantly worse than normal subjects (p < 0.0001). Stereopsis in TST was significantly correlated with the area of RD (p < 0.005), difference of postoperative spherical equivalent between two eyes (p < 0.05), postoperative logMAR BCVA (p < 0.005), difference of postoperative logMAR BCVA between two eyes (p < 0.01), and low-contrast visual acuity (p < 0.05). Stereopsis in TNO stereotest showed significant association with postoperative logMAR BCVA (p < 0.05). Stereopsis in both stereotests were significantly worse in patients with macula-off RD than macula-on RD (p < 0.005, p < 0.01 respectively). No significant relationship was found between stereopsis and other factors. Multiple regression analysis revealed that macular status (on/off) had a significant correlation with both stereopsis in TST and TNO stereotest (p = 0.028, p = 0.019 respectively), whereas other clinical parameters were not relevant.
Stereopsis is significantly deteriorated in patients after RD surgery than in normal subjects. Stereopsis was associated with the difference in refraction between two eyes, postoperative visual acuity and contrast sensitivity, and preoperative macular status.
评估单侧孔源性视网膜脱离（RD）手术成功后的立体视，并研究立体视与临床因素之间的关系。
对75例RD手术后患者和28例年龄匹配的正常受试者，使用Titmus立体视测试（TST）和TNO立体视测试测量立体视。收集临床数据，包括年龄、性别、视网膜裂孔的圆周尺寸、RD的面积和持续时间、黄斑状态、手术方式、术后等效球镜度、最佳矫正视力的最小分辨角对数（logMAR BCVA）、低对比度视力、术后晶状体状态（晶状体/人工晶状体）以及术后视网膜前膜（ERM）的存在情况，以确定与立体视相关的因素。
手术后患者的立体视明显比正常受试者差（p < 0.0001）。TST中的立体视与RD面积（p < 0.005）、两眼术后等效球镜度差异（p < 0.05）、术后logMAR BCVA（p < 0.005）、两眼术后logMAR BCVA差异（p < 0.01）以及低对比度视力（p < 0.05）显著相关。TNO立体视测试中的立体视与术后logMAR BCVA显著相关（p < 0.05）。黄斑脱离的RD患者在两种立体视测试中的立体视均比黄斑未脱离的患者明显更差（分别为p < 0.005，p < 0.01）。未发现立体视与其他因素之间存在显著关系。多元回归分析显示，黄斑状态（脱离/未脱离）与TST和TNO立体视测试中的立体视均显著相关（分别为p = 0.028，p = 0.019），而其他临床参数无关。
RD手术后患者的立体视比正常受试者明显恶化。立体视与两眼屈光差异、术后视力和对比敏感度以及术前黄斑状态有关。
