Promising therapeutic targets for neuroprotection in retinal disease.

Abstract

Purpose of review: Neurodegeneration is a common endpoint of various blinding retinal diseases. Yet, despite exciting advances in disease treatment, there continues to exist a critical need for the development of neuroprotective strategies to prevent retinal cell death. Here, we summarize the recent advances in neuroprotective strategies.

Recent findings: From laboratory deciphering of the mechanisms involved in disease, many novel neuroprotective strategies have emerged and are currently under investigation for the treatment of various retinal and ocular diseases such as inherited retinal degeneration, retinal detachment, diabetic retinopathy, age-related macular degeneration, macular telangiectasia type 2, and glaucoma. These strategies include gene therapies, Fas inhibition, and targeting inflammatory, metabolic and reduction-oxidation abnormalities. Interestingly, investigation of several treatments across different diseases suggests shared neuroprotection mechanisms that can be targeted regardless of the particular disease.

Summary: Retinal neuroprotection can improve treatment of different retinal diseases. Fortunately, the current landscape, with a plethora of novel neuroprotective therapies, portends a better future for patients.
