■本研究旨在评估影响手术结局的预后因素,包括视力(VA)改善,新生血管性青光眼(NVG)患者的青光眼手术后。
■回顾性分析了116例(116只眼)NVG患者接受小梁切除术或Ahmed青光眼瓣膜植入术的病历。主要结果指标是术后6个月的手术成功率,定义为足够的眼内压(IOP)降低(IOP≤21mmHg,降低≥20%,无论局部用药)没有额外的青光眼手术,矮个子,或者进展到没有光的感知。基于除了上述定义之外是否观察到VA的改善,成功被分类为完全或合格。
■6个月的完全和合格成功率分别为44.6%和92.2%,分别。年龄(p=0.001),术前最佳校正VA(p=0.031),VA降低的持续时间(p=0.001),闭合角状态(p=0.013),和病因(p=0.007)在有和没有完全成功的组之间存在显着差异。多变量分析显示年龄(比值比[OR]1.05;p=0.026),VA降低的持续时间(OR1.05;p=0.016),根据完全成功标准,360°闭合角状态(OR3.27;p=0.031)是手术失败的危险因素,但不是合格的成功标准。
■如果视力丧失的持续时间没有延长并且角度状态没有完全闭合,则在相对较年轻的年龄进行青光眼手术后,NVG患者的视力预后改善和成功的眼压降低。
UNASSIGNED: This study aimed to evaluate the prognostic factors affecting surgical outcomes, including visual acuity (VA) improvement, after glaucoma surgery in patients with neovascular glaucoma (NVG).
UNASSIGNED: The medical records of 116 patients (116 eyes) with NVG who had undergone trabeculectomy or Ahmed glaucoma valve implantation were reviewed retrospectively. The primary outcome measure was surgical success at 6 postoperative months, defined as sufficient intraocular pressure (IOP) reduction (IOP ≤21 mmHg, ≥20% reduction, regardless of topical medication use) without additional glaucoma surgery, hypotony, or progression to no light perception. Success was categorized as complete or qualified based on whether an improvement in VA was observed in addition to the abovementioned definition.
UNASSIGNED: The complete and qualified success rates at 6 months were 44.6% and 92.2%, respectively. Age (p = 0.001), preoperative best-corrected VA (p = 0.031), duration of decreased VA (p = 0.001), closed-angle status (p = 0.013), and etiology (p = 0.007) differed significantly between the groups with and without complete success. Multivariate analysis revealed that age (odds ratio [OR] 1.05; p = 0.026), duration of decreased VA (OR 1.05; p = 0.016), and 360° closed-angle status (OR 3.27; p = 0.031) were risk factors for surgical failure according to the complete success criteria, but not the qualified success criteria.
UNASSIGNED: Patients with NVG showed improved visual prognosis and successful IOP reduction after glaucoma surgery at a relatively younger age if the duration of visual loss was not prolonged and the angle status was not completely closed.
