To review new clinically relevant data regarding the intraocular treatment of noninfectious uveitis.
Triamcinolone acetonide, the most commonly used intravitreal corticosteroid for treatment of uveitis and uveitic macular oedema has a limited duration of action and is associated with a high risk of corticosteroid-induced intraocular pressure (IOP) rise and cataract. Recent advances have led to the development of sustained-release corticosteroid devices using different corticosteroids such as dexamethasone and fluocinolone acetonide. Treatment options for patients who have previously exhibited corticosteroid hypertensive response have also expanded through the use of new noncorticosteroid intravitreal therapeutics such as methotrexate and antivascular endothelial growth factor (anti-VEGF) agents.
Ozurdex dexamethasone implant appears to have a better safety profile, and a slightly long-lasting effect than triamcinolone acetonide. The Retisert implant allows the release of corticosteroids at a constant rate for 2.5 years, but it requires surgical placement and its use is associated with a very high risk of cataract and requirement for IOP-lowering surgery. For patients who are steroid responders, methotrexate may offer a better alternative to corticosteroid treatment than anti-VEGF agents, but controlled trials are required to confirm this.
回顾非感染性葡萄膜炎眼内治疗的新的具有临床相关性的数据。
作为治疗葡萄膜炎和葡萄膜炎性黄斑水肿最常用的眼内皮质类固醇,曲安奈德的作用持续时间有限,并且与皮质类固醇引起的眼内压(IOP)升高和白内障的高风险相关。最近的进展导致了使用不同皮质类固醇(如地塞米松和氟轻松)的缓释皮质类固醇装置的发展。对于以前表现出皮质类固醇高血压反应的患者,通过使用新的非皮质类固醇眼内治疗药物,如甲氨蝶呤和抗血管内皮生长因子(anti-VEGF)药物,治疗选择也有所扩大。
Ozurdex 地塞米松植入物似乎具有更好的安全性和稍长的作用持续时间,优于曲安奈德。Retisert 植入物可使皮质类固醇以恒定速率释放长达 2.5 年,但需要手术植入,并且其使用与白内障和需要降低 IOP 手术的极高风险相关。对于对类固醇有反应的患者,甲氨蝶呤可能比抗 VEGF 药物提供了更好的皮质类固醇治疗替代方案,但需要进行对照试验来证实这一点。
