A 36-year-old highly myopic woman was referred for management of both cataract and glaucoma. Her ocular history included retinal detachment repair in each eye, 9 years earlier in the right eye and 7 years earlier in the left eye. Although the patient did not remember specific details of the retinal surgery, she recalled that she had a "gas bubble" postoperatively in the right eye, but not the left eye. She also had a very dense nuclear cataract in the right eye, but only mild nuclear sclerosis in the left eye.At presentation, the patient's corrected distance visual acuity (CDVA) was 20/125 in the right eye, with a large myopic shift (-18.25 + 2.00 × 175). Her CDVA in the left eye was 20/20 (-11.00 + 1.00 × 20). It is notable that she is contact lens-intolerant.Her angle was wide open in each eye, and each optic nerve had severe myopic saucerization and cupping. The axial length was 28.5 mm and 28.7 mm in the right eye and left eye, respectively.The intraocular pressure (IOP) at presentation was 18 mm Hg in the right eye and 20 mm Hg in the left eye; each eye was treated with a topical β-blocker, α-2 agonist, and a prostaglandin. The highest IOP measurements before treatment were 27 mm Hg and 25 mm Hg in the right eye and left eye, respectively. The pachymetry was 545 μm in the right eye and 540 µm in the left eye.Her visual fields and nerve fiber layers on optical coherence tomography (OCT) are shown in and , respectively.(Figure is included in full-text article.)(Figure is included in full-text article.)Cataract surgery was scheduled along with a coincident glaucoma procedure. It is noteworthy that intraoperatively, the right capsular bag was very loose. Indeed, the capsular bag could not be penetrated with the cystotome, which only dimpled the capsule severely but would not penetrate it. Accordingly, a super-sharp, #15 blade was used to pierce the capsule and initiate the capsulotomy.Whereas the zonule was obviously loose, the remainder of the procedure was completed without incident and the intraocular lens (IOL) placed in the capsular bag with perfect centration. It was unclear whether the loose zonule was a consequence of the patient's vitreoretinal surgery or whether there was a systemic cause for her zonulopathy. Although it was not suspected before the surgery, in retrospect, this patient had the classic body habitus of Marfan syndrome. Moreover, subsequent surgery in the fellow left eye found the zonule to be quite loose, but not as severe as in the right eye.How would you manage this patient's glaucoma? Given the finding of very loose zonular fibers, would you initiate a workup for Marfan syndrome? Certain microinvasive glaucoma surgery (MIGS) procedures are labeled for mild-to-moderate glaucoma. How strictly do you adhere to such labeling? Do you ever use a MIGS device in severe glaucoma?
一位 36 岁的高度近视女性被转介来管理白内障和青光眼。她的眼部病史包括每只眼的视网膜脱离修复,右眼为 9 年前,左眼为 7 年前。尽管患者不记得视网膜手术的具体细节,但她记得右眼手术后有“气液泡”,但左眼没有。她的右眼还患有非常严重的核性白内障,而左眼只有轻度核硬化。
就诊时,患者右眼的矫正远视力(CDVA)为 20/125,有很大的远视漂移(-18.25 + 2.00 × 175)。她左眼的 CDVA 为 20/20(-11.00 + 1.00 × 20)。值得注意的是,她不能戴隐形眼镜。
每只眼的眼压(IOP)均为 18mmHg,右眼和左眼分别为 20mmHg;每只眼均接受局部β受体阻滞剂、α-2 激动剂和前列腺素治疗。右眼和左眼的最高 IOP 测量值分别为 27mmHg 和 25mmHg。右眼和左眼的角膜厚度分别为 545μm 和 540μm。
她的视野和神经纤维层在光学相干断层扫描(OCT)上的表现如图和图所示。
白内障手术与同时进行的青光眼手术一起安排。值得注意的是,术中右眼囊袋非常松弛。事实上,用囊切刀无法穿透囊袋,囊切刀只是严重地压凹了囊袋,但无法穿透它。因此,使用了非常锋利的 #15 刀片刺穿囊袋并开始囊切开术。
虽然悬韧带明显松弛,但其余手术过程顺利完成,人工晶状体(IOL)完美地植入囊袋中。尚不清楚松弛的悬韧带是患者的玻璃体视网膜手术的结果,还是其存在全身性悬韧带病的原因。尽管在手术前并未怀疑,但回想起来,该患者具有马凡综合征的典型体型。此外,对同眼左眼的后续手术发现悬韧带非常松弛,但不如右眼严重。
你将如何治疗该患者的青光眼?鉴于发现非常松弛的悬韧带纤维,你是否会开始马凡综合征的检查?某些微创青光眼手术(MIGS)程序适用于轻度至中度青光眼。你会严格遵循这种标签吗?你是否曾在严重青光眼患者中使用 MIGS 设备?
