Ocular Toxocariasis: Long-Term Follow-Up and Prognosis of Patients following Vitrectomy

Purpose: To investigate the outcomes of surgical treatment in patients with ocular toxocariasis and identify prognostic factors. Methods: We retrospectively reviewed the medical records of 56 consecutive patients who underwent vitrectomy. Results: The mean follow-up was 20.7 months. Visual acuity (VA) improved in 70.4% of patients by the final visit, but VA was better than Snellen 20/70 in only 31.5% of patients. Preoperative VA was closely correlated with final VA (P = 0.001). Macular involvement was associated with final VA worse than 20/70 (P = 0.03). The most common postoperative complications were ocular hypertension (19.6%) and retinal detachment (12.5%). Seven patients (12.5%) experienced recurrent inflammation postoperatively, but no preoperative factors were associated with recurrent inflammation. Conclusion: Surgical treatment could rescue visual function in patients with ocular toxocariasis but their prognosis was unfavorable. Preoperative VA was associated with final VA, whereas macular involvement was associated with poor visual outcomes.

目的：探讨眼弓蛔虫病患者手术治疗的结果，并确定预后因素。方法：我们回顾性分析了56例连续接受玻璃体切除术患者的病历。结果：平均随访时间为20.7个月。到最后一次随访时，70.4%的患者视力（VA）有所提高，但只有31.5%的患者视力优于斯内伦视力表20/70。术前视力与最终视力密切相关（P = 0.001）。黄斑受累与最终视力低于20/70相关（P = 0.03）。最常见的术后并发症是高眼压（19.6%）和视网膜脱离（12.5%）。7例患者（12.5%）术后出现炎症复发，但没有术前因素与炎症复发相关。结论：手术治疗可挽救眼弓蛔虫病患者的视功能，但其预后不佳。术前视力与最终视力相关，而黄斑受累与不良视力结果相关。
