Within 2-3 weeks after injection, PT began noticing blurred vision, color distortion, flashing lights around perimeter of eye, extreme sensitivity to light and gooey discharge from left eye. Thus began endless appts, tests and eye surgery. In the 6 months following the onset of his issues, he has seen his regular opthamologist, a glaucoma specialist and a retinal specialist for a total of 9 times and not one has determined what is causing his vision issues.At his regular eye appt on January 13, 2021, his vision was perfect and his glaucoma pressures were 10 in right eye and 21 in the left eye, which was in the realm of what they had checked since being diagnosed in 1984. He made an appointment with his opthamologist for 4/14/2021 to see if he could shed some light on the issues he is having. The office called and moved the appt to 4/22. At that appt, his pressures were 24 in his right eye (not the affected eye at that time) and 25 in his left eye. His left eye was extremely irritated so the doctor prescribed steroid drops to help calm down the irritation but could not make a determination for why the eye was irritated and the pressures were up, not to mention patient could hardly see the letters on the eye chart.He saw the opthamologist again on 5/19/2021 to see if the drops had helped. There was no improvement in vision or pressure. The pressures were 23 in R eye and 30 in left eye. The doctor recommended PT see a glaucoma specialist. They couldn't see him until 6/28/2021. At that appointment, his pressures were 22 in R and 36 in Left.Dr. preformed a visual field and recommended that drainage tubes (shunts) be inserted to drain fluid and relieve pressure. The surgery was scheduled for 7/27/2021. On 7/28/2021, PT returned to the doctor's office for a follow-up visit to check the surgery results. The pressure in his left eye was 29. Right wasn't checked. On 8/23/2021, PT had an appt with Dr. again and the left eye pressure was 25, which historically was not a good pressure for PT's left eye. However, the doctor seemed pleased that it had come down a few points in a month. The doctor still could not explain why the vision was still blurred and eye irritated, colors distorted and the flashing was still occurring. We decided to go to his opthamologist on 8/30/2021 and see if he could maybe correct the vision with glasses for right now. PT couldn't read the eye chart and during the exam, Dr. found a hole in his macula in his right eye and a warp in the macula in his left eye. His pressures were good at 16 and 15. Dr.. referred him to a retinal specialist. On 9/02/2021, PT saw retinal specialist, and the pressures checked 18 in the R eye and 23 in the L eye. He explained about a vitrectomy procedure which would repair the hole in the macula in the right eye. Needless to say, we are extremely discouraged at the inability to diagnose what has caused the blurred vision and other symptoms he is experiencing. He told retinal specialist he would have to think about the vitrectomy because his left eye is incapacitated now and if he has this procedure, he would be incapacitated in both eyes for a while. We have another appointment with the glaucoma specialist and the retinal specialist. We are hoping there is no permanent damage done but, at this time, we cannot say that there isn't. There has been no improvement since 3/2021. There is no exact date or time for the onset of the issues.
