A man in his 30s presented for assessment of long-standing iris lesions in both eyes. He was unaware of any recent changes in the size or number of these lesions. His visual acuity measured 20/25 (6/7.5) OU, and his intraocular pressures were 14 mm Hg OU. The patient had noticed progressive visual obscuration in his left eye.He was not taking any ocularmedications, and his only systemic medication was an oral β-blocker. He was otherwise healthy, and his family history was noncontributory.

On a slitlamp examination, multiple brown masses were noted at the pupillary margin in both eyes, encroaching on the central visual axis (Figure). There was no inflammation in
the anterior chamber or vitreous. The findings of the posterior pole examination were unremarkable bilaterally.

When further history was taken, the patient reported undergoing endovascular stent graft repair for a thoracic aortic dissection about 5 years prior. A computed tomography scan was ordered, which showed a well-placed thoracic stent graft extending from the level of the left subclavian artery to the distal descending thoracic aorta. opthalmologist performed Nd:YAG laser cystotomy on the left eye to collapse the iris flocculi encroaching on the central visual axis, and this resulted in an improvement in visual symptoms.
