Glaucoma is the main cause of irreversible blindness worldwide. This disease is characterized by apoptosis of retinal ganglion cells (RGC) and visual field loss that seems to be related to elevated intraocular pressure (IOP). Several lines of evidences have implicated the crucial role of mitochondrial dysfunction in the pathogenesis of glaucoma. Increased mitochondrial oxidative stress in RGC may underlie or contribute to susceptibility of RGC to apoptosis. In our work we (i) designed a rabbit model of chronic, moderately elevated IOP for studying glaucoma and (ii) demonstrated efficacy of mitochondria-targeted antioxidant SkQ1 as a tool to reverse several traits of experimental glaucoma induced by a series of injections of hydroxypropylmethylcellulose (HPMC) to the anterior chamber of the rabbit eye. It is shown that 6 months instillations of drops of 0.2.5-5 microM solution of SkQ1 normalize IOP and eye hydrodynamics and abolish an increase in lens thickness that accompanies glaucoma.
