Review of non-arteritic anterior ischaemic optic neuropathy

This article reviews the risk factors, clinical presentation and therapies that have been investigated for non-arteritic anterior ischaemic optic neuropathy (NAAION). Additionally, it provides an update from recent rodent and primate models, offering a new insight into the pathophysiology of...

Visual fields and OCT in hydroxychloroquine retinopathy

It has been recommended that patients on hydroxychloroquine be monitored regularly for retinopathy. However, there has not been an agreement as to the best screening test for hydroxychloroquine toxicity, which may include visual fields (VF), fundus autofluorescence, spectral domain optical...

Case report of Leber hereditary optic neuropathy (LHON)

This case report presents a 74-year-old male patient who developed LHON, with a previous diagnosis of bilateral macular holes. LHON occurs predominantly in healthy young men and onset in older age ranges increases the likelihood that the patient will have...
