糖尿病视网膜病变（PDR）是工业化国家成人视力丧失的主要原因。由于严重玻璃体出血而具有光感（LP）或手部运动（HM）敏锐度的PDR患者需要玻璃体手术。本研究的目的是确定患有LP或HM的PDR患者的视力是否可以使用低视力评估器（LoVE）分级为更精细的步骤。此外，我们确定了LoVE结果是否与视网膜电图（ERG）的振幅、视网膜脱离（RD）的存在或术后视力预后相关。LOVE仪器是测量光刺激阈值的主观设备，并配备了一副带有白色发光二极管作为刺激的护目镜。本文对19例因玻璃体积血而无法观察眼底的PDR患者进行了LOVE阈值的测量，其视力均为LP或HM。13例HM视力患者的LoVE阈值范围为25.0 - 40.0 dB，6例LP视力患者的LoVE阈值范围为20.0 - 40.0 dB。9例RD患者的LoVE阈值明显低于10例非RD患者（P < 0.001）。LoVE阈值与ERG a波和b波振幅以及术后最佳矫正视力（BCVA）相关（a波：r = 0.70，p < 0.001; b波：r = 0.71，p < 0.001;术后BCVA：r = 0.46，p < 0.05）。这些结果表明，LOVE能够将具有传统LP和HM视力的PDR患者的视功能分级为更精细的步骤。因此，在预测玻璃体积血患者的术后视力方面，LoVE是一种非常有价值的设备。
Proliferative diabetic retinopathy (PDR) is a leading cause of visual loss in adults in industrialized countries. PDR patients with light perception (LP) or hand movement (HM) acuity due to severe vitreous hemorrhage require vitreous surgery. The purpose of this study was to determine whether the visual acuity of PDR patients with LP or HM can be graded into finer steps with the Low Vision Evaluator (LoVE). In addition, we determined whether the LoVE results are correlated with the amplitude of the electroretinogram (ERG), the presence of retinal detachment (RD), or postoperative visual prognosis. The LoVE instrument is a subjective device that measures the thresholds for light stimulus and is equipped with a pair of goggles with white light-emitting diodes as the stimulus. We measured the LoVE thresholds of 19 PDR patients, whose fundi could not be observed due to vitreous hemorrhage and whose visual acuity was LP or HM. The 13 patients with HM vision had LoVE thresholds that ranged from 25.0 and 40.0 dB, and the 6 patients with LP vision had LoVE thresholds that ranged from 20.0 and 40.0 dB. The LoVE thresholds of 9 patients with RD were significantly lower than those of 10 patients without RD (p < 0.001). The LoVE thresholds were correlated with the amplitude of the a- and b-waves of the ERG and the postoperative best-corrected visual acuity (BCVA) (a-wave: r = 0.70, p < 0.001; b-wave: r = 0.71, p < 0.001; postoperative BCVA: r = 0.46, p < 0.05). These results indicate that the LoVE is capable of grading the visual function of PDR patients with conventional LP and HM vision into finer steps. Thus, the LoVE is an invaluable device in predicting the postoperative visual acuity of patients with vitreous hemorrhage.
