Arteriovenous malformation (AVM) in the occipital lobe has been known to cause visual symptoms and headaches. Arteriovenous malformation is a congenital anomaly that consists of abnormal arteries and veins without the presence of a capillary bed. The majority of patients initially manifest intracranial hemorrhage, while others manifest symptoms of seizures, headaches, and progressive neurological deficits. ⋯ Clinical differentiation of migraine from arteriovenous malformation is often regarded as difficult, since both conditions may manifest similar features of visual aura, with or without headaches. Early diagnosis and treatment of AVM may reduce the risk of serious complications. When a patient manifests alarming headaches with or without visual aura, neuro-imaging workup is warranted to rule out sinister causes.

Review Case Reports
Ceroid lipofuscinosis, neuronal 3, Juvenile-Batten disease: case report and literature review.
Ocularly, Batten disease is characterized by a rapid deterioration of vision, progressing to blindness within a few years. Onset typically occurs at between 5 and 10 years of age. The fundus shows a bull's eye maculopathy, diffuse pigmentary degeneration, arteriolar attenuation and optic atrophy, and an extinguished ERG. ⋯ Batten disease is the most likely of the ceroid lipofuscinoses to be manifested in an ophthalmic practitioner's office before the diagnosis of the underlying condition. Although there currently is no treatment for this condition, making the correct diagnosis is important for appropriate low-vision management, educational planning, and genetic counseling.
