A 73-year-old woman had right dacryocystitis, intense conjunctival hyperemia and chemosis, marginal corneal ulcers, and abscesses and conjunctival cultures that were positive for beta hemolytic streptococci. A distinct lucid interval separated the peripheral corneal ulcers and infiltrates from the corneoscleral limbus. Gram stain of corneal scrapings revealed polymorphonuclear leukocytes but no bacteria, and corneal cultures were negative for bacteria. The peripheral corneal ulcers and abscesses in our patient with the lacrimal conjunctivitis of Morax clinically resembled the catarrhal ulcers found with staphylococcal blepharitis. A hypersensitivity or toxic reaction to streptococci or their products may have played a role in the development of the marginal ulcers in this patient.
一名73岁女性患有右泪囊炎、结膜明显充血和水肿、角膜边缘溃疡、脓肿，结膜培养显示β溶血性链球菌阳性。周边角膜溃疡和浸润与角膜缘之间有明显的清晰间隔。角膜刮片革兰氏染色显示有多形核白细胞但无细菌，角膜培养细菌阴性。我们这位患有莫拉克斯泪囊炎结膜炎患者的周边角膜溃疡和脓肿在临床上类似于葡萄球菌性睑缘炎所见的卡他性溃疡。对链球菌或其产物的超敏反应或毒性反应可能在该患者边缘溃疡的发生中起了作用。
