Our dad needs help with unexpected medical bills

Hi, our dad’s name is Richard Leiva. He lives back in Ecuador, our home country. Recently he found out some distressing news about his eye. Due to his recent high blood pressure, a blood clot formed behind his eye. After receiving some medical help, he found out he needed to start treatment as soon as possible to save his vision. His treatment consists of three to four rounds of injections and medications. These sessions cost about $1,200 each. We appreciate all the help we can get, thank you!!!
