Abstract:
UNASSIGNED: To report a case of a bilateral complex uveitic glaucoma (UG) with pupillary block, rupture of the anterior lens capsule, and malignant glaucoma in a young high-myopic patient and to report anterior segment optical coherence tomography (AS-OCT) findings initially and following surgery.
UNASSIGNED: A 21-year-old high-myopic woman who had a history of anterior uveitis with extensive posterior synechiae, presented with acute bilateral ocular pain, redness, and blurred vision following bilateral Nd: YAG laser peripheral iridotomy (LPI).
UNASSIGNED: Visual acuity was limited to light perception in both eyes (OU), with a flat anterior chamber (AC) and anterior luxation of lens fragments. Intraocular pressure (IOP) was over 60 mmHg OU. AS-OCT showed closed angles and hyperreflective heterogeneous material within the flat AC. The iris and lens fragments were plated against the corneal endothelium OU. We performed an urgent pars plana vitrectomy associated with lensectomy. It was uneventful in OU. Repeated AS-OCT revealed a deep AC, widely open angles, and aphakia. IOP was lowered to 9 mmHg and visual acuity improved to 5/10 in OU.
UNASSIGNED: Performing LPI might be harmful in the presence of UG with extensive posterior synechia, resulting in complex mechanism glaucoma with aqueous misdirection syndrome associated with a pupillary block due to anterior lens luxation, even in high-myopic eyes. Nd: YAG LPI should not be performed simultaneously in OU, especially in pathologic eyes, to prevent bilateral vision-threatening complications. AS-OCT was of great help, allowing easy and detailed ultrastructural assessment of the ACs, and iridocorneal angles before and after surgery.
摘要:
未经授权:报告一例伴有瞳孔阻滞的双侧复杂性葡萄膜型青光眼(UG),晶状体前囊破裂,一名年轻高度近视患者的恶性青光眼,并报告最初和手术后的眼前节光学相干断层扫描(AS-OCT)发现。
未经证实:一名21岁的高度近视女性,有前房葡萄膜炎伴广泛的后房粘连病史,出现急性双侧眼部疼痛,发红,双侧Nd:YAG激光周边虹膜切开术(LPI)后视力模糊。
未经授权:视敏度仅限于双眼(OU)的光感,平坦的前房(AC)和晶状体碎片的前脱位。眼内压(IOP)超过60mmHgOU。AS-OCT显示平坦AC内的闭合角度和超反射异质材料。将虹膜和晶状体碎片铺在角膜内皮OU上。我们进行了与晶状体切除术相关的紧急平坦部玻璃体切除术。在OU是平安无事的。重复的AS-OCT显示深AC,广泛开放的角度,和无晶状体。OU的眼压降低至9mmHg,视力提高至5/10。
未经授权:在存在广泛的后粘连的UG的情况下,执行LPI可能是有害的,导致复杂机制的青光眼伴房水误导综合征与前晶状体脱位引起的瞳孔阻滞相关,即使是高度近视的眼睛。Nd:YAGLPI不应在OU中同时进行,尤其是在病态的眼睛中,预防双侧视力威胁并发症。AS-OCT帮了大忙,允许对ACs进行简单详细的超微结构评估,手术前后虹膜角膜角度。
