My maternal uncle was having difficulty to see through right eye. Thus, some eye angiography test was given & it was reported that he was diagnosed with CSR. Some eye drops were given. After a month check up, the eye problem was persistent & he was given blood test & MRI of Brain & pupil. MRI reported that thickening of the retino choroid layer on right side with few non specific with few vitreous opacities & optic nerve were normal.   All are normal except he was diagnosed with high thyroid. But the opthalmologist was unable to detect the exact cause of his blurriness of right eye. Kindly help us.
