Purpose: Idiopathic intracranial hypertension (IIH) leads to optic nerve head swelling and optic atrophy if left untreated. We wanted to assess an easy to perform volumetric algorithm to detect and quantify papilledema in comparison to retinal nerve fiber layer (RNFL) analysis using optical coherence tomography (OCT).
Methods: Participants with and without IIH underwent visual acuity testing at different contrast levels and static perimetry.
Introduction: Although the interest is growing in topical low-dose atropine to control myopia in schoolchildren worldwide, its use in children of European ancestry remains controversial and solid evidence is sparse. The Oxford Centre for Evidence Based Medicine (OCEBM) classifies the evidence for this therapy as level I for East Asian populations, but only level IV in non-Asian populations.
Methods: Fifty-six children, aged a median of 11 years (range 6-17), were analysed after 12 months of topical treatment with 0.
Myopia is on the increase worldwide and will become a major challenge over the next decades in terms of secondary ophthalmologic complications. There are effective therapeutic options available to slow or prevent the progression of myopia. So far, it has not been investigated whether there are possible additive effects of these interventions.

- Patients who underwent mesiotemporal lobe resection for epilepsy often experience visual field defects (VFD), which can impact activities like driving.
- The study reviewed data from 366 patients who had various surgical procedures, focusing on the types and severity of VFD post-surgery.
- Results indicated that 73% of patients experienced VFD, with 48% having defects that affected their ability to drive; however, those who had a subtemporal approach had significantly fewer and less severe driving-relevant VFD.
Background And Purpose: To assess the accuracy of ocular B-mode sonography and of standard head computed tomography (CT) as screening tools for intraocular hemorrhages related to subarachnoid hemorrhage (SAH).
Methods: 46 patients with spontaneous SAH were examined using ocular B-mode sonography and underwent funduscopy as gold standard for detection of ocular hemorrhages (OH). Additionally, all head CT scans done during the hospital stay of the study population were rated by a neuroradiologist for the presence of OH.
Marked dissociation of photopic and mesopic contrast sensitivity even in normal observers.

Aim: Although contrast vision is not routinely tested, it is important: for instance, it predicts traffic incidents better than visual acuity. Mesopic contrast sensitivity (CS) testing approximates low-lighting conditions but entails dark adaptation, which can disrupt clinical routine. In receptor-specific diseases, a dissociation of photopic and mesopic sensitivity would be expected, but can photopic CS act as a surrogate measure for mesopic CS, at least for screening purposes?
Methods: Photopic and mesopic contrast sensitivities were studied in three groups: 47 normal subjects, 23 subjects with glaucoma, and three subjects with cataract.
