To report two cases demonstrating the regression of corneal neovascularization and clearing of corneal opacification in patients with Stevens Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) undergoing prosthetic replacement of the ocular surface ecosystem (PROSE) treatment.
Four eyes of 2 patients were analyzed. Regression of neovascularization and clearing of corneal opacification was observed in both patients. All 4 eyes demonstrated improvement in visual acuity with treatment. With treatment, both patients ultimately discontinued all prescribed topical therapies. It was discovered upon review of these cases that all 4 eyes were managed with PROSE devices designed with back-surface channeled haptics.
There currently is no known literature reporting on long-term regression of corneal neovascularization or clearing of corneal opacity in SJS or TEN patients with the use of scleral prosthetic devices. This report of 2 cases highlights the improvement in corneal function with PROSE treatment involving the use of channeled designs in patients with SJS or TEN. More research is needed to better understand how PROSE or scleral lens design features affect patient outcomes and why some patients may show regression in corneal neovascularization.
报告两例在接受眼表生态系统假体置换术(PROSE)治疗的史蒂文斯-约翰逊综合征(SJS)和中毒性表皮坏死松解症(TEN)患者中,角膜新生血管消退及角膜混浊清除的病例。
对2例患者的4只眼进行了分析。两名患者均观察到新生血管消退及角膜混浊清除。所有4只眼经治疗后视力均有改善。经治疗,两名患者最终均停用了所有规定的局部治疗。回顾这些病例时发现,所有4只眼均采用了带有后表面带槽触觉结构的PROSE装置进行处理。
目前尚无已知文献报道使用巩膜假体装置治疗SJS或TEN患者时角膜新生血管的长期消退或角膜混浊的清除情况。这两例病例报告突出了PROSE治疗对SJS或TEN患者角膜功能的改善,该治疗采用了带槽设计。需要更多研究以更好地理解PROSE或巩膜镜片设计特征如何影响患者预后,以及为何一些患者的角膜新生血管可能会消退。
