BACKGROUND: Iridoschisis is a rare condition that is characterized by the
separation of the iris stroma into layers, with portions of the anterior layer
floating freely in the aqueous humour. Here, we report three cases of
iridoschisis that were complicated by either a cataract or glaucoma. Based on
these cases, we speculate that the scope of iridoschisis has a rare association
with intraocular pressure and the loss of corneal endothelial cells after
surgery, which is mainly due to the surgery and not iridocorneal mechanical
contact. CASE PRESENTATION: We report three cases of iridoschisis, two of which
were complicated by cataracts and the third by glaucoma. Patient 1 was a
69-year-old man with bilateral iridoschisis complicated by a cataract but not
glaucoma, even though the entire anterior layer of the iris stroma in the right
eye presented as white atrophic strands. To prevent the detached iris fibrils
from invading the phacoemulsification tip and the irrigation/aspiration hand
piece port, the separated iris stroma that was floating freely in the aqueous
humour was cut with scissors immediately before the cataract extraction. Patient
2 was an 87-year-old woman with iridoschisis complicated by a cataract in the
right eye. We successfully performed cataract surgery on the right eye without a
pupillary device. Patient 3 was a 66-year-old man who presented with increased
intraocular pressure with bilateral iridoschisis. He was discharged and
prescribed with a combination of four glaucoma drugs. CONCLUSIONS: Patients with
iridoschisis should have continuous follow-up because complications may occur,
and extra care from ophthalmologists is required.
