Suggest Treatment For Blurred Vision In An Elderly Person

Hello Dr. Meyer, My mother 92 she has what I believe they call grey star with her eyes. That is her vision in the middle is blurred while the outside area she is somewhat clear (this a least what I remember from what she told me). She s present in a old age home under care. The treatment the doctors are using here is to remove the water from her eyes. (Again I no expect, this is what she told me). I given to understand that there no real cure to to this problem and that one simply has to live with it. So here my questions; 1) Can this be cured, treated or corrected? 2) My mother love to read, but with this condition she can t now. Is there something we might be able give her that assist her to help to read once again? 3) When she go out of the house, I see the strong sunlight hurts her eyes. Might sunglasses help here? If so what might you be able to recommend. I thank you and hope to hear from you shortly. Until then, with kind regards, S. Engels 8185 Winkel, Switzerland
