To observe the effects of visual neuroplasticity training on visual perception, visual quality, and macular blood flow in patients with concomitant strabismus postoperatively.
In total, 108 patients underwent binocular strabismus correction operation, and some patients underwent neuroplasticity training. All patients underwent clinical ophthalmic examination, including measurement of best-corrected visual acuity, spherical equivalent, axis length, optical coherence tomography angiography, optical quality analysis system, and visual perception examinations.
A total of 78 patients received neuroplasticity training for 1 month postoperatively, and 30 patients did not receive training. All patients underwent a visual perception examination preoperatively and at 1 day, 1 week, and 1 month postoperatively. Macular blood flow and visual quality were examined preoperatively and at 1 month postoperatively. Postoperative visual perception was better than preoperative visual perception ( P < 0.05). After neuroplasticity training, the visual perception of the trained subjects was better than that of the untrained subjects ( P < 0.05), and the blood flow in the macular area of the trained patients was lower than that of the untrained subjects ( P < 0.05). The visual quality of the untrained subjects was lower than that of the trained patients ( P < 0.05).
Visual inspection system could accurately evaluate binocular visual perception in patients with concomitant strabismus. After surgical alignment of the strabismus patient, training can stimulate and integrate the formation of stereovision in a short period of time, maintain the visual quality of patients after surgery, and provide conditions for the formation of binocular visual signals and binocular stereovision, but in the short term, it will lead to the decrease of macular blood vessel density and perfusion density. However, the long-term effects of training have not been proven.
观察视觉神经可塑性训练对视知觉、视觉质量和黄斑血流的影响。
共有 108 例患者接受双眼斜视矫正手术,部分患者接受神经可塑性训练。所有患者均进行临床眼科检查,包括最佳矫正视力、球镜等效、轴长、光学相干断层扫描血管造影、光学质量分析系统和视觉感知检查。
共有 78 例患者术后 1 个月接受神经可塑性训练,30 例未接受训练。所有患者术前及术后 1 天、1 周和 1 个月进行视觉感知检查。术前及术后 1 个月检查黄斑血流和视觉质量。术后视觉感知优于术前(P<0.05)。经过神经可塑性训练,训练组的视觉感知优于未训练组(P<0.05),训练组患者的黄斑区血流低于未训练组(P<0.05)。未训练组的视觉质量低于训练组(P<0.05)。
视觉检查系统能准确评估斜视患者的双眼视觉感知。斜视患者手术后,通过训练可以在短时间内刺激和整合立体视觉的形成,维持术后患者的视觉质量,为双眼视觉信号和双眼立体视觉的形成提供条件,但短期内会导致黄斑血管密度和灌注密度下降。然而,训练的长期效果尚未得到证实。
