Case presentation (RE: right eye; LE: left eye) (a); the AS-OCT image demonstrates severe stromal thinning in the left eye (b); left eye penetrating keratoplasty (c); right eye corneal perforation and subsequent penetrating keratoplasty (d). AS-OST, anterior segment-optical coherence tomography.

At baseline, she had very low visual acuity, corresponding to counting fingers at 50 cm in the right eye and hand motion in the left eye, with conjunctival hyperemia, deep stromal edema, corneal opacity and, in particular, a bilateral corneal neurotrophic ulcer, worse in left eye (shown in Fig. 1a). A few days later, despite bandage contact lenses and slight improvement, the left eye corneal stroma had become very thin as evidenced by anterior segment-optical coherence tomography (shown in Fig. 1b), and we performed a penetrating keratoplasty (shown in Fig. 1c) to avoid a certain corneal perforation trying to obtain a better visual outcome in a patient with very low visual acuity. Twenty days later, she developed asymptomatic corneal perforation in her right eye and underwent a penetrating keratoplasty in this eye as well (shown in Fig. 1d).
