Hello Doctor, hope you re doing great! What I m about to discuss could be nothing but rather to be safe than sorry, as they say. I was having difficulty seeing when driving at night, so I went to an optometrist for an eye test. The specialist indicated that I have a dialated pupil and can mean 2 things, either very normal or the posibility of a tumour. Having this said, I recently talked to my sister about not remebering some things that happened in the past, especially conversations and special occurances, which is a concern for me. I don t know if this can be related. Help and advise would be really appreciated. Enjoy the rest of your day. Rgds Malcolm
