Evidence of multidomain mild cognitive impairment in idiopathic intracranial hypertension.

Background: Idiopathic intracranial hypertension (IIH), a disorder of unknown etiology, may occur in all age groups, but is most common in young obese women. Goals of treatment are to preserve vision and alleviate symptoms, including intractable headache, pulsatile tinnitus, and nausea. Cognitive function is not addressed routinely during clinical evaluation of IIH patients.

Comparison of peripapillary retinal nerve fiber layer loss and visual outcome in fellow eyes following sequential bilateral non-arteritic anterior ischemic optic neuropathy.

Aim: To report on the correlation of structural damage to the axons of the optic nerve and visual outcome following bilateral non-arteritic anterior ischemic optic neuropathy.

Methods: A retrospective review of the medical records of 25 patients with bilateral sequential non-arteritic anterior ischemic optic neuropathy was performed. Outcome measures were peripapillary retinal nerve fiber layer thickness measured with the Stratus optical coherence tomography scanner, visual acuity and visual field loss.

The use of spectral-domain optical coherence tomography for differentiating long-standing central retinal artery occlusion and nonarteritic anterior ischemic optic neuropathy.

Background And Objective: To report on the efficacy of macular and optic nerve spectral-domain optical coherence tomography (SD-OCT) in differentiating between long-standing central retinal artery occlusion (CRAO) and nonarteritic anterior ischemic optic neuropathy (NAION).

Patients And Methods: SD-OCT scans of the macula and optic nerve in 24 patients with unilateral optic atrophy secondary to CRAO (12 patients) and NAION (12 patients) were compared both qualitatively and quantitatively for differentiating features.

Results: In patients with long-standing CRAO, there was a significantly greater (P < .

Retinal thickness in patients with mild cognitive impairment and Alzheimer's disease.

Objectives: Mild cognitive impairment (MCI) may represent a transition to early Alzheimer's disease (AD). The retinal nerve fiber layer (RNFL) is composed of axons originating in retinal ganglion cells that eventually form the optic nerves. Previous studies have shown that degenerative changes occur in optic nerve fibers and manifested as thinning of RNFL in patients with AD.

Orbital tumors treated using transcranial approaches: surgical technique and neuroophthalmogical results in 41 patients.

Object: Orbital tumors can be divided schematically into primary lesions, originating from the orbit itself, and secondary lesions, extending to the orbit from neighboring structures. These tumors are variable in their biological nature and in their location. The authors evaluate 41 cases of benign and malignant tumors involving the orbit and discuss the surgical challenge, which involves tumor removal, preserving visual function and cosmetic reconstruction.
