Extensive bilateral corneal edema 6 weeks after cataract sur
Surgeons may be unaware of the ability of plant toxins to cause corneal damage. Therefore, corneal damage following intraocular surgery due to plant toxins may be misdiagnosed as postoperative infection.

Case Presentation
A 74-year-old man with no history of uveitis, keratitis, or allergic eye disease underwent uneventful bilateral cataract surgery with one day interval in August 2015. His best corrected distant visual acuity (CDVA) following surgery was 1.0 and 1.2 in the right and left eyes, respectively. Intraocular pressures and the number of corneal endothelial cells (2301/mm2 in the right eye and 2171/mm2 in the left) were within the normal range. The patient reported hyperemia and reduced visual acuity in both eyes one evening at 6 weeks postoperatively and visited Maejima eye clinic the following day. On examination, extensive hyperemia and corneal stromal edema with Descemet’s folds were observed in both eyes. His CDVA was 0.2 in both eyes, and central corneal thicknesses were 786 ?m and 756 ?m in the right and left eyes, respectively. Intraocular pressure measurements and detailed observations of the anterior chamber were not possible due to the presence of corneal edema.
