case_images: Anterior eye segment of the patient with keratitis caused by Paederus fuscipes at initial presentation. a Image of the anterior segment using slit-lamp microscopy at the initial presentation. Corneal oedema, hyperaemia, and conjunctival chemosis with discharge are observed. b Image of the face of the patient at initial presentation. Blepharitis with oedema is noted. c Image of the cornea after fluorescein staining. Almost all corneal epithelial defects can be identified. d Gram staining of the corneal scrape. Although there are numerous neutrophils and epithelial cells, no gram-positive cocci or gram-negative bacteria can be observed.

case_images: On initial presentation, blepharitis, strong oedema of the eyelid, conjunctival chemosis, and hyperaemia were observed in the left eye (Fig. 1a, b). Fluorescein staining confirmed that corneal epithelium defects were present in almost all areas accompanied by cell infiltration (Fig. 1c). Gram staining of the corneal scrape demonstrated numerous neutrophils and epithelial cells, but no bacteria, including gram-positive cocci or gram-negative rods/cocci (Fig. 1d).
case_images: Anterior eye segment of the patient with Paederus fuscipes-induced keratitis 2 months after injury. a Image of the anterior segment using slit-lamp microscopy 2 months after the injury. Keratitis has been completely treated, and the cornea is clear. b Image of the cornea after fluorescein staining. The corneal epithelium is intact. A topographic image of the anterior cornea evaluated 2 months after the injury (c) and a topographic image of the cornea 4 years before the injury (d). Corneal irregularity is not higher than that noted 4 years prior.

case_images: Two months after the patient's initial visit, the corneal opacity had resolved completely, and a visual acuity of 20/16 was achieved (Fig. 2a, b). Corneal topography demonstrated that irregular astigmatism of the anterior cornea was not higher (Fig. 2c) than it had been 4 years prior (Fig. 2d).
