This retrospective study aimed to assess the effectiveness of using MicroPulse transscleral cyclophotocoagulation (µP-TSCPC) in patients who had previously undergone pars plana vitrectomy (PPV), depending on the endotamponade used.
For the study, a total of 60 patients were enrolled who underwent PPV followed by tμP-TSCPC as a result of an increase in intraocular pressure (IOP) over the norm of 21 mmHg. In this group of patients, 20 received silicone oil endotamponade during PPV, 20 received sulfur hexafluoride gas SF6, and in another 20 a differentiated balanced salt solution (BSS) was used.
The main indications for conducting PPV were (1) retinal detachment (silicone oil endotamponade was used; n = 12); (2) dislocation/subluxation of the patient's own or artificial intraocular lens (balanced salt solution (BSS) endotamponade was used; n = 11); (3) the presence of an epiretinal membrane and/or a macular hole (BSS endotamponade was used; n = 9, or SF6; n = 20); and (4) hemorrhage into the vitreous chamber (silicone oil endotamponade was used; n = 8).
The choice of endotamponade used during PPV was not found to determine the effectiveness of µP-TSCPC treatment. The effectiveness of µP-TSCPC in patients after PPV depended, above all, on the etiology of the disease, for which PPV was previously performed. The lowest effectiveness of µP-TSCPC was noted in cases where the reason for conducting PPV was hemorrhage into the vitreous chamber and silicone oil endotamponade was used, while the highest effectiveness was noted in cases where PPV was conducted owing to the presence of an epiretinal membrane and/or a macular hole and SF6 endotamponade was used.
本回顾性研究旨在评估根据所使用的眼内填充剂，微脉冲经巩膜睫状体光凝术（µP-TSCPC）在既往接受过玻璃体切除术（PPV）的患者中的有效性。
本研究共纳入60例因眼压（IOP）升高超过21 mmHg标准而接受PPV并随后接受µP-TSCPC的患者。在这组患者中，20例在PPV期间接受硅油眼内填充，20例接受六氟化硫气体（SF6）填充，另外20例使用了平衡盐溶液（BSS）。
进行PPV的主要指征为：（1）视网膜脱离（使用硅油眼内填充；n = 12）；（2）患者自身或人工晶状体脱位/半脱位（使用平衡盐溶液（BSS）眼内填充；n = 11）；（3）视网膜前膜和/或黄斑裂孔的存在（使用BSS眼内填充；n = 9，或SF6；n = 20）；以及（4）玻璃体内出血（使用硅油眼内填充；n = 8）。
未发现PPV期间所使用的眼内填充剂的选择能决定µP-TSCPC治疗的有效性。µP-TSCPC在PPV后患者中的有效性首先取决于先前进行PPV的疾病病因。在因玻璃体内出血而进行PPV并使用硅油眼内填充的情况下，µP-TSCPC的有效性最低，而在因视网膜前膜和/或黄斑裂孔的存在而进行PPV并使用SF6眼内填充的情况下，µP-TSCPC的有效性最高。
