Case Series: West African Crystalline Maculopathy.

Significance: West African crystalline maculopathy is a rare crystalline maculopathy without a clear etiology. Although the crystals do not appear to be visually significant, there may be a role in the breakdown of the blood-retina barrier within the pathogenesis of this disorder.

Purpose: The purpose of this case series is to describe two cases of West African crystalline maculopathy.

Necrotising herpetic retinopathies: a review and progressive outer retinal necrosis case report.

Necrotising retinopathies can be visually devastating. Most often associated with the viral family Herpesviridae and seen in both immune-competent and immunocompromised hosts, possible complications of necrotising retinopathies include progressive retinal necrosis with or without macular involvement, optic neuropathy and ultimately, secondary retinal detachment. Examples include progressive outer retinal necrosis, acute retinal necrosis and cytomegaloviral retinitis.

Progressive, asymptomatic papilledema as the presenting sign of a Chiari I malformation.

Background: Chiari I malformation (CM1) is the caudal herniation of the cerebellar tonsils into the foramen magnum. It can cause several neurological signs and symptoms, or be asymptomatic. Papilledema is a potential, but unusual, manifestation of CM1.
