We report a case of benign intracranial
hypertension
(BIH) resulting from corticosteroid withdrawal. A 36-year-old woman was admitted to hospital because of an intractable headache. A neurological examination on admission showed no abnormalities other than a headache and nausea. CT, MRI, and angiogram examinations showed no abnormalities. Hematological and laboratory data were also normal. Continuous monitoring of her cerebrospinal fluid (CSF) pressure showed a value of over 25 mmHg during sleep, but papilledema was not observed. A diagnosis of BIH was made, with corticosteroid withdrawal considered to be the most probable cause. The patient was given isosorbide solution for 3 months. However, her clinical condition continued to deteriorate; she eventually began to develop visual loss,
photopsia
, and memory disturbances. She underwent lumboperitoneal shunt surgery, which immediately eliminated the headache,
photopsia
, and memory disturbances. She regained her vision over a five-month period. BIH should be considered as a differential diagnosis when an intractable headache develops after corticosteroid withdrawal, especially in young women.

Long-term efficacy and safety profile of pegaptanib was evaluated for age-related macular degeneration (AMD) with choroidal neovascularization. Sixty-one AMD patients from phase II clinical trial were entered into an extended trial and followed up for more than 2 years. Pegaptanib sodium 0.3 mg was administered once every six weeks. Changes in visual acuity were evaluated using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. The number of responders and adverse events were monitored. The mean change in visual acuity decreased by 10.3 letters for up to 199 weeks (62-199 weeks; mean 140 weeks) during follow-up. There were 77.4% responders at the beginning (54 weeks since the beginning of phase II trial) and 56.6% at the end of the extended trial. Adverse events were found in 57 of 61 patients (93.4%); 36 of the events (59.0%) were due to a preparation procedure, while 12 adverse events (19.7%), including retinal hemorrhage (3 events; 4.9%), anterior chamber inflammation (2 events; 3.3%), macular degeneration, floaters,
photopsia
, retinal vessel aneurysm, vitreous hemorrhage, ocular hypertension, arteriosclerosis obliterans and
hypertension
(1 event; 1.6%, respectively) were associated with pegaptanib sodium. Thus, the majority of adverse events was at least in part a result of the preparation procedure for injection. Based on the long-term efficacy and tolerability data of this trial, pegaptanib sodium appears to be beneficial for preventing the worsening of visual acuity caused by age-related macular degeneration with choroidal neovascularization.

Idiopathic intracranial hypertension (IIH) is defined as a syndrome of increased intracranial pressure without causative lesions on magnetic resonance imaging. The symptoms of IIH patients are headache, transient visual obscurations,
photopsia
, retrobulbar pain, diplopia, visual loss and papilledema. Management of intracranial
hypertension
is initially medical, using a combination of managed weight body reduction and diuretic, non-steroid and steroid therapy. Surgical therapy may be required to stabilize vision.

This report is of two cases of asymmetrical papilloedema in patients with asymmetrical intraocular pressures (IOPs). The first patient presented with headaches, transient visual obscurations (TVOs), and elevated IOPs, and was found to have increased intracranial pressure caused by a torcula meningioma. He developed papilloedema after his IOPs were pharmacologically lowered; the papilloedema resolved after the IOP became elevated again after stopping his glaucoma drops, and then again returned as the IOP reduced when the drops were restarted. The second patient with a history of Sturge-Weber syndrome requiring previous left trabeculectomy, presented with left-sided TVOs,
photopsia
, and pulsatile tinnitus caused by idiopathic intracranial
hypertension
. Asymmetrical papilloedema was observed, worse in the eye with the lower IOP following trabeculectomy. These cases suggest that asymmetric IOP may be one factor that can influence the development of asymmetric papilloedema. Ophthalmologists finding disc swelling at low normal pressures should ask about symptoms of raised ICP, and neuro-ophthalmologists confronted with asymmetrical disc swelling should routinely measure IOP.

Posterior reversible encephalopathy syndrome (PRES) is associated with several symptoms; of those, visual acuity loss, light oversensitivity (photophobia), and light flashes (
photopsia
) are known as PRES-related eye symptoms. We report a post-partum woman with PRES associated with hemolysis, elevated liver enzymes, and low platelets syndrome (HELLP), in whom color vision abnormality (achromatopsia) was the sole manifestation. Cesarean section was performed at 28 weeks due to headache, epigastralgia, and severe
hypertension
. HELLP became evident after delivery. On post-partum day 1, she complained of achromatopsia, stating: "all things look brownish-gray". Ophthalmologic examination was normal, but brain magnetic resonance imaging showed occipital lobe lesions, indicative of PRES, and, interestingly, also color vision center (area V4) lesions, suggesting that the achromatopsia had been caused by brain damage. It may be prudent to question HELLP patients concerning achromatopsia.
