In the year 2005 for my mother Retina was detached to 80% , during operation Silicon Oil was inserted, after the operation sight was very low, and it was also from the pin hole. At present for last 6months she is not able to see properly ( Low sight also ) as colours like blue, red are coming in vision. As per doctors assessment the only solution is to remove the oil, bu the risk is of total blind-ness, Today's level of vision is 10% which also may get lost.
Her other eye was not having any vision, this eye was having lots of water during the year 1980, treatment was on but after few days vision is lost.
Her today's age is 71 she is not having any other medical issues.
