We aim to report a case of a middle-aged woman with bilateral idiopathic elevated episcleral venous pressure (IEEVP) and its difficulties in the diagnostic approach. Particularly in this case, the atypical feature of ocular hypertension without glaucomatous optic nerve damage may be misleading. We present a 66-year-old woman with longstanding bilateral “red eyes.” Clinical findings included bilateral episcleral vessel engorgement and tortuosity and raised intraocular pressure with open iridocorneal angles. Despite ocular hypertension, glaucomatous neuropathy was absent and confirmed by normal structural (optical coherence tomography) and functional (standard automated perimetry) tests. The systemic workup was unremarkable. Magnetic resonance angiography showed bilateral dilated superior ophthalmic veins. Cerebral digital subtraction angiography was requested, and no carotid-cavernous fistula (or other significant vascular findings) was identified. The diagnosis of IEEVP was assumed. In conclusion, our case highlights the systematic investigation necessary in cases of bilateral episcleral vessel engorgement and tortuosity and the possible differential diagnosis to be considered to rule out life-threatening causes of elevated episcleral venous pressure. It is important for clinicians to be aware of IEEVP even in patients with atypical features that despite significative ocular hypertension had no glaucomatous damage.
