Purpose. To present a unique case of Non-Hodgkin’s-Lymphoma- (NHL) associated compressive optic neuropathy.Method. An 89-year-old male presenting with acute unilateral visual loss and headache.Results. Patient was initially diagnosed with occult giant cell arteritis; however after visual acuity deteriorated despite normal inflammatory markers, an urgent MRI scan revealed an extensive paranasal sinus mass compressing the optic nerve.Conclusion. Paranasal sinus malignancies occasionally present to the ophthalmologist with signs of optic nerve compression and must be included in the differential diagnosis of acute visual loss.

Acute Visual Loss

A 38-year-old man presented with an acute right homonymous visual field defect due to occipital lobe infarct caused by hyperhomocysteinaemia. Visual field testing, magnetic resonance imaging, laboratory studies, and genetic analysis were carried out. On magnetic resonance imaging, a left occipital lesion with bright signal on the diffusion-weighted and fluid-attenuated inversion recovery images suggested a diagnosis of an acute infarct. Blood tests revealed raised homocysteine of 52.08 μmol/L (reference range, <15 μmol/L) and genetic analysis showed the patient to be homozygote to 5, 10-methylenetetrahydrofolate reductase deficiency. Hyperhomocysteinaemia is a rare causes of acute visual loss due to cerebral ischaemia and should always be suspected and investigated with the appropriate tests to diagnose the condition and limit further vision deterioration.

Cavernous sinus thrombosis (CST) is a rare condition that can cause death, neurologic disability, and visual loss. A pre-teen with septic CST leading to ocular hypertension and acute visual loss was treated at our institution with thrombectomy and thrombolysis of the cavernous sinuses and superior ophthalmic veins. Successful recanalization of the bilateral cavernous sinuses and superior ophthalmic veins was achieved in two separate procedures without complication. The patient showed immediate symptomatic relief. He was neurologically intact without visual deficits at the 2 month follow-up. This is the first report in the literature showing the feasibility of cavernous sinus thrombectomy using current devices and techniques. Early endovascular therapy may help preserve vision in patients with acute CST.
