Anosognosia for cortical blindness, also called Anton's syndrome, is a rare neurological disorder usually following bilateral lesions to occipital cortices. Neuropsychological, morphological and functional neuroimaging (SPECT and fMRI) findings are reported in a patient who incurred Anton's syndrome after an ischaemic lesion confined to the left occipital lobe involving the corpus callosum. The present case study suggests that Anton's syndrome may also follow from lesions disconnecting the occipital cortices.

Damage to the primary visual pathway can cause vision loss. Some cerebrally blind people retain degraded vision or sensations and can perform visually guided behaviors. These cases motivate investigation and debate on blind field conscious awareness and linked residual neural processing.

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological condition characterized by reversible subcortical vasogenic edema that primarily affects the posterior areas of the brain. Subcortical vasogenic edema resulting from endothelial injury and hypertension is the pathogenesis. Here, we present a 23-year-old female patient with systemic lupus erythematosus (SLE) and lupus nephritis who developed PRES following Rituximab (a monoclonal anti-CD-20 antibody) administration.

The PERSIAN eye cohort study is a population-based study that evaluates the overall prevalence of cataracts and their subtypes (nuclear sclerosis, cortical, and PSC) in Iran. In this study, from January 2015 to September 2021, 16,016 participants over 35 years of age from four provinces who were selected by random cluster sampling were examined. Demographic information, education, socioeconomic status, and place of residence were collected through interviews.

Visual deficit after spinal surgery is rare but tragic. The main causes include external eye injury, cortical blindness, central retinal artery occlusion, and ischemic optic neuropathy. In scoliosis surgery, this complication potentially arises from prolonged surgical time, high blood loss, prone position, hydroelectrolytic imbalance, and cerebrospinal fluid loss.
