Case in brief
A woman in her 40s experienced recurrent retro-orbital pain and was initially misdiagnosed with migraine and later glaucoma due to suspected intermittent angle closure. Despite controlled intraocular pressure, she suffered progressive visual loss. Further investigation revealed optic disc pallor and diffuse retinal nerve fibre layer thinning, leading to the diagnosis of chronic relapsing inflammatory optic neuropathy. High-dose corticosteroids improved her condition, confirming steroid dependency.
Diagnostic / clinical pearl
Clinicians should consider alternative diagnoses, such as chronic relapsing inflammatory optic neuropathy, in cases of atypical glaucoma presentations with progressive visual loss despite intraocular pressure control.
