BACKGROUND/AIMS Progressive diaphyseal dysplasia (PDD) is a rare, autosomal dominant, osteosclerotic dysplasia affecting both endochondrally and intramembranously derived bones. Severely affected patients can develop progressive stenosis of the optic canals and compressive optic neuropathy. Although raised intracranial pressure (ICP) has been described in patients with PDD in whom visual loss h...

Septo-optic dysplasia also referred to as de Morsier syndrome and is a disorder of early brain development. Three characteristic features are under development (hypoplasia) of the optic nerve, abnormal formation of structures along the midline of the brain (such as absence of septum pellucidum and corpus callosum dysgenesis) and pituitary hypoplasia. CASE REPORT Female, born at 40 weeks of gest...

Background: Intraosseous meningiomas often display clinical and radiologic features that can be confused for fibrous dysplasia. Histopathology usually confirms the diagnosis. We present a case initially misdiagnosed as fibrous dysplasia by histopathology. Methods: A 58-year-old male presented with worsening proptosis and vision loss. He was previously diagnosed with fibrous dysplasia at an outs...

METHODS Names and hospital numbers of patients with midline clefts were obtained from the ophthalmology and genetics database. Six patients were identified who had the following common findings: midline facial cleft with midline cleft lip and palate; hypertelorism; abs...

Septo-Optic Dysplasia (SOD) is a rare disorder with postulated genetic and environmental etiology. Whilst initially considered as a very rare disease (defined as incidence of approx. 1 in 50,000 births) recent data gave a reported incidence of 1 in 10,000, with equal sex distribution. The diagnosis of SOD is predominantly a clinical one, and made with the presence of two or more features of the...
