Keratoconus may progress to acute corneal hydrops even after cross-linking. In some cases, keratoconus progresses during pregnancy. In this report, we present a case of a patient with increased anterior stromal resistance after cross-linking that would favor nonprogression of keratoconus during pregnancy.
We report that cross-linking is likely to have had a protective effect in a white pregnant patient with acute corneal hydrops who showed rapid improvement, as documented by corneal topography. Improvement occurred within 8 days, whereas up to 250 days are reported in the literature. No keratoconus progression occurred in the 20-month follow-up period.
Cross-linking failed to prevent the occurrence of acute corneal hydrops after rupture of Descemet's membrane but most likely helped to accelerate the resolution of the condition. Corneal hardening resulting from cross-linking may have also contributed to stabilizing keratoconus during pregnancy.
圆锥角膜即使在交联术后仍可能进展为急性角膜水肿。在某些情况下,圆锥角膜在孕期会进展。在本报告中,我们呈现了一例交联术后前基质阻力增加的患者病例,这有利于圆锥角膜在孕期不进展。
我们报告,交联术可能对一名患有急性角膜水肿的白人孕妇起到了保护作用,该患者病情迅速改善,角膜地形图记录了这一情况。改善在8天内出现,而文献报道的时间长达250天。在20个月的随访期内未发生圆锥角膜进展。
交联术未能预防后弹力层破裂后急性角膜水肿的发生,但很可能有助于加速病情的缓解。交联导致的角膜硬化也可能有助于在孕期稳定圆锥角膜。
