Shield-shaped corneal ulcers and corneal plaques in vernal keratoconjunctivitis are associated with delayed epithelial healing, as well as the risks of infectious keratitis and sterile stromal ulceration. Significant visual impairment due to scarring and irregular astigmatism may result from central corneal lesions.
Three eyes with central corneal lesions resulting from vernal keratoconjunctivitis were treated by excimer laser after active vernal keratoconjunctivitis was controlled and inflammatory plaque overlying the shield ulcers was removed.
All three eyes showed rapid reepithelialization within 1 week. Spectacle-corrected visual acuity of 20/30 or better was obtained in each eye.
In selected patients, excimer laser phototherapeutic keratectomy may be a useful adjunct in the treatment of shield-shaped corneal ulcers and plaques in vernal keratoconjunctivitis.
春季角结膜炎中的盾形角膜溃疡和角膜斑与上皮愈合延迟以及感染性角膜炎和无菌性基质溃疡的风险相关。中央角膜病变可能导致因瘢痕形成和不规则散光而造成的严重视力损害。
在活动性春季角结膜炎得到控制且覆盖盾形溃疡的炎性斑被清除后，对3只因春季角结膜炎导致中央角膜病变的眼睛进行了准分子激光治疗。
所有3只眼睛在1周内均显示出快速的上皮再形成。每只眼睛的矫正视力均达到20/30或更好。
对于选定的患者，准分子激光角膜切削术可能是治疗春季角结膜炎中盾形角膜溃疡和角膜斑的一种有用辅助方法。
