{Abstract}: Glaucoma is a leading cause of irreversible blindness worldwide which affects all age groups. It is often identified by high intraocular pressure, characteristic optic neuropathy, and vision loss. Due to multifactorial nature of glaucoma pathogenesis, the molecular events responsible for its precipitation are currently poorly understood. Mitochondrial DNA (mtDNA) variations which are inherited maternally are being closely studied in recent times to elucidate the effect on glaucoma. Mitochondrial genetic studies till date have found a possible link between Leber hereditary optic neuropathy loci and glaucoma but with conflicting views. Furthermore, whole mtDNA studies in glaucoma points at the involvement of oxidative phosphorylation complex I and specifically the NADH dehydrogenase 5 gene in glaucoma. This review focuses on identifying the potential genes and variations in the maternally inherited mtDNA which might be involved in glaucoma pathogenesis.
