Vitreoretinal disorders comprise a large group of diseases including retinal ischemia–reperfusion injury(RIRI),posterior uveitis,etc.,which often have poor vision prognosis^([1]).With the ongoing effort in understanding the pathogenetic mechanisms of these diseases,new therapeutic methods are also being developed^([2]).Among various treatments,drug therapy has been widely adopted due to ease of handling.

Hearing loss is one of the most common sensory disorders worldwide,affecting approximately 466 million people,including 34 million children[1].Genetic mutations accounts for approximately 60%of inherited hearing loss cases[2,3].These genetic changes result in a wide variety of clinical manifestations,ranging from nonsyndromic hearing loss(NSHL)to over 400 syndromes involving hearing loss and from mild adult-onset hearing loss to profound congenital deafness,covering the entire spectrum of Mendelian inheritance.
