A 39-year-old woman with rheumatoid arthritis, sleep apnea and a body mass index of 55 presented with nausea, vomiting and floaters in the right eye for two days. Two weeks prior, she developed positional headaches, blurry vision and transient visual obscurations. On presentation, her best corrected visual acuity was 20/25 in each eye, there was no relative afferent pupillary defect and the examination of external structures and anterior segment was unremarkable.\nFunduscopic examination revealed Frisen grade 4 papilledema in the right eye with vitreous, subretinal and intraretinal hemorrhages, and grade 3 in the left eye with flame-shaped hemorrhages (A, ).\nHead CT with contrast appeared normal, an MRI was not possible due to body habitus and weight restrictions. Lumbar puncture under fluoroscopic guidance revealed opening pressure of 310 mm CSF with normal composition. Humphrey visual field 24-2 SITA Fast was reliable with an enlarged blind spot and a few central changes in the right eye (mean deviation −4.00 dB) and was essentially full with mild central depression in the left eye (mean deviation −3.55 dB).\nShe was started on acetazolamide 500 mg twice daily, which was titrated up to 1500 mg twice daily with gradual resolution of symptoms over a month. At two month follow up, the vitreous hemorrhage had resolved and there was marked improvement in the papilledema bilaterally ( C, D).
A 42-year-old obese woman presented to her optometrist after she noticed “after images” following bright light exposure in her left eye (OS). She also noticed transient blurred vision with position changes but denied any regular headaches or pulsatile tinnitus. She denied ever having a severe onset headache. She was referred to neuro-ophthalmology and was found to have a visual acuity of 20/20 in both eyes. Humphrey 24-2 SITA-Fast visual fields showed nonspecific depressed points right eye (OD; MD −6.18 dB) and showed an enlarged blind spot OS (MD −4.84 dB). Dilated fundus examination showed moderate optic disc edema in both eyes with preretinal, intraretinal, and subretinal hemorrhages around the left optic disc (shown in Fig. ). Her blood pressure measured 140/100 and her hemoglobin was normal. Magnetic resonance imaging/magnetic resonance venography was performed and showed signs of raised ICP without a secondary cause. Lumbar puncture showed an opening pressure of 32 cm of water and normal cerebrospinal fluid (CSF) contents. She was started on acetazolamide 500 mg twice-daily (BID) and telmisartan 40 mg daily and the optic disc edema improved and resolved after 4 months with significant weight loss. She maintained normal visual function and the ODH resolved at 3 months. The final Humphrey mean deviation was −3.42 dB OD and −2.98 dB OS.
