The objective of this report is to describe a case of crystalline keratopathy caused by the Streptococcus mitis group corresponding to a patient who attended hospital for discomfort in her right eye. The ophthalmological examination showed an interrupted stitch of 10-0 nylon suture without tension and with attached mucus secretions. The loose suture was removed under aseptic conditions. Moxifloxacin 0.5 % eye drops were topically indicated. The treated eye successfully epithelialized and evolved favorably. However, after 15 days, a white tree-shaped infiltrate developed. A corneal sample was taken in the operating room, threading the intrastromal path of the removed stitch with a 7-0 vicryl suture. Vancomycin 50 mg/ml drops were indicated. The infiltrate, which was stable for 45 days, later increased its size and tissue necrosis occurred with danger of corneal perforation. A bipedicle conjunctival flap was performed in the affected corneal area, which evolved favorably. After spontaneous conjunctival flap retraction, only corneal scarring and neovascularization outside the visual axis were observed.
本报告的目的是描述一例由缓症链球菌引起的结晶性角膜病变病例，该患者因右眼不适入院。眼科检查显示10-0尼龙缝线中断，无张力，伴有附着的黏液分泌物。在无菌条件下拆除了松动的缝线。局部使用0.5%莫西沙星滴眼液。治疗的眼睛成功上皮化且病情好转。然而，15天后，出现了白色树枝状浸润。在手术室取了角膜样本，用7-0可吸收缝线穿过已拆除缝线的基质内路径。局部使用50mg/ml万古霉素滴眼液。浸润稳定了45天，后来尺寸增大，出现组织坏死，有角膜穿孔的危险。在受影响的角膜区域进行了双蒂结膜瓣手术，病情好转。结膜瓣自发回缩后，仅观察到视轴外的角膜瘢痕和新生血管形成。
