The purpose of this study was to report 2 cases experiencing a transient decrease in their vision due to the development of acute myopia after an uneventful prolene gonioscopy-assisted transluminal trabeculotomy (GATT) surgery.
A 52-year-old woman with primary open-angle glaucoma and an 8-year-old boy with juvenile glaucoma underwent uneventful GATT surgery.
On the postoperative first day, both patients had mild shallow anterior chamber and intraocular pressures measured as 19 and 16 mm Hg, respectively. Both patients had myopia measured as -4.5 and -6.0 D, respectively. Fundus examination was unremarkable in the first patient, whereas it showed bilateral optic disc cupping and retinal nerve fiber layer atrophy in the second patient. In the first patient, supraciliary effusion was detected by using ultrasound biomicroscopy. Ultrasound biomicroscopy could not be performed in the second patient, but ocular ultrasonography revealed a thin layer of suprachoroidal fluid. Myopia was completely regressed, and visual acuity increased within 1 week of the follow-up in both patients. At the sixth month of the follow-up, intraocular pressures in both patients were under control without any antiglaucoma medications.
Transient decrease in vision after the GATT surgery might occur secondary to supraciliary effusion leading to acute, transient myopia.
本研究旨在报告 2 例无并发症聚烯丙基青光眼小梁切开术（GATT）手术后发生急性近视导致视力短暂下降的病例。
一名 52 岁女性原发性开角型青光眼和一名 8 岁男孩青少年型青光眼患者行无并发症 GATT 手术。
术后第一天，两名患者均出现轻度浅前房，眼压分别为 19mmHg 和 16mmHg。两名患者均有近视，分别为-4.5D 和-6.0D。第一例患者眼底检查未见异常，第二例患者则显示双侧视盘杯盘比和视网膜神经纤维层萎缩。第一例患者经超声生物显微镜检测发现睫状突上腔积液。第二例患者无法进行超声生物显微镜检查，但眼部超声显示有一层薄薄的脉络膜上腔积液。两名患者的近视均在 1 周的随访内完全消退，视力提高。随访 6 个月时，两名患者的眼压均得到控制，无需任何抗青光眼药物。
GATT 手术后视力短暂下降可能继发于睫状突上腔积液导致的急性、短暂性近视。
