The purpose was to quantify and compare the severity of aniseikonia in patients undergoing vitrectomy for various retinal disorders.
We studied 357 patients with retinal disorders including epiretinal membrane (ERM), macular hole (MH), cystoid macular edema with branch / central retinal vein occlusion (BRVO-CME / CRVO-CME), diabetic macular edema (DME), macula-off rhegmatogenous retinal detachment (M-off RD), and macula-on RD (M-on RD) as well as 31 normal controls. The amount of aniseikonia was measured using the New Aniseikonia Test preoperatively and at 6 months postoperatively.
Of all patients, 59% presented aniseikonia. Preoperative and postoperative mean aniseikonia were 4.0 ± 4.1% and 3.0 ± 3.6%, respectively. In particular, 68% of patients with ERM had macropsia, and approximately half of MH, RVO-CME, DME, and M-off RD patients had micropsia. Preoperative aniseikonia was significantly severe in ERM than in other disorders. Vitrectomy improved aniseikonia only in MH, while visual acuity was improved in all disorders except CRVO-CME.
More than half of the patients showed aniseikonia preoperatively. A majority of ERM patients exhibited macropsia, whereas MH, RVO-CME, DME, and macula-off RD patients presented micropsia. The aniseikonia score was greatest in ERM patients. In most retinal disorders, surgery significantly improved visual acuity, but not aniseikonia.
本研究旨在量化并比较因各种视网膜疾病接受玻璃体切除术患者的不等像视严重程度。
我们研究了357例患有视网膜疾病的患者，包括视网膜前膜（ERM）、黄斑裂孔（MH）、伴有视网膜分支/中央静脉阻塞的黄斑囊样水肿（BRVO-CME/CRVO-CME）、糖尿病性黄斑水肿（DME）、黄斑脱离孔源性视网膜脱离（M-off RD）和黄斑在位视网膜脱离（M-on RD），以及31名正常对照者。术前及术后6个月使用新型不等像视测试测量不等像视的程度。
所有患者中，59%存在不等像视。术前及术后平均不等像视分别为4.0±4.1%和3.0±3.6%。特别是，68%的ERM患者有视物显大症，约一半的MH、RVO-CME、DME和M-off RD患者有视物显小症。ERM患者术前不等像视明显比其他疾病严重。玻璃体切除术仅改善了MH患者的不等像视，而除CRVO-CME外的所有疾病患者视力均有改善。
超过一半的患者术前存在不等像视。大多数ERM患者表现为视物显大症，而MH、RVO-CME、DME和黄斑脱离患者表现为视物显小症。ERM患者的不等像视评分最高。在大多数视网膜疾病中，手术显著改善了视力，但未改善不等像视。
