RESUMO
Anterior segment colobomas can be found isolated or in combination with changes in the posterior segment. A coloboma of the ciliary zonule leads to alteration of the lens profile with myopia and astigmatism. Amblyopia and cataract development may also occur. We present two cases with a coloboma of the zonule with different degrees of expression and the most important differential diagnoses are discussed.

Ocular ischemic syndrome (OIS) is a group of ocular diseases caused by chronic artery occlusion usually involving the internal carotid artery. Patients suffer from visual loss and pain. OIS is a rare disease which can be confounded with diabetic retinopathy or an older central retinal vein occlusion. The only therapy is to treat the neovascular complications. Due to the high mortality of OIS patients, medical and neurological examinations are mandatory. We discuss the clinical findings and diagnostic and therapeutic options of OIS patients in this paper.
