Granulomatosis with polyangiitis (GPA), formerly referred to as Wegener’s disease, is a form of ANCA-associated vasculitis. It manifests mainly in the kidneys and the upper respiratory tract, but ocular involvement is not uncommon. In this article, four cases with ocular manifestations are presented with comprehensive photographic documentation. We describe the way to proper diagnosis, which may be long, the possible treatment, and the final outcomes. Our patients had the following ocular manifestations of GPA: retinal vasculitis, anterior necrotizing scleritis, medial orbital wall and orbital floor erosion with middle face deformation, compressive optic neuropathy due to retrobulbar inflammatory mass, and the abscess of the eyelids, inflammatory intraorbital mass causing exophthalmos and diplopia. This manuscript includes the description of severe forms of GPA, the initial signs and symptoms, relapses, and difficulties in achieving remission. The extraocular involvement is described with diagnostic modalities and laboratory findings. One of the reported cases was diagnosed by an ophthalmologist on the basis of ocular symptoms in the early stages of the disease. Our outcomes are compared with those discussed in the literature.
