{Abstract}: OBJECTIVE: Iris cysts may arise secondary to surgical or nonsurgical trauma, potentially leading to corneal decompensation via mechanical injury to the adjacent endothelium. However, no well-established protocol exists for the treatment for corneal edema arising therefrom.
METHODS: A 58-year-old white male presented with an iris mass of his left eye; it occupied 1/3rd the anterior chamber volume and directly contacted the corneal endothelium. The cornea was diffusely edematous, and best corrected visual acuity (BCVA) measured 20/70 (0.3). Corneal endothelial decompensation secondary to iris cyst was diagnosed. Treatment consisted of endophotocoagulation and vitrectomy probe removal of the cyst wall, with Descemet membrane endothelial keratoplasty (DMEK) also performed as a single, combined procedure. The patient subsequently experienced a resolution of his corneal edema and disappearance of his iris cyst, without recurrence of either condition. BCVA improved to 20/25 (0.8).
CONCLUSIONS: Iris cyst may be a rare cause of corneal decompensation. Viable treatment may entail a single-stage procedure involving endophotocoagulation and vitrectomy probe application to the cyst wall combined with DMEK.
