As you know, XXX is a very nice XX year old woman, who suffers from macular degeneration. As you are familiar with her medical history, I will not recount that here. XXX lives at home with her husband. XXX’s main concern is reading. She also has difficulty with personal hygiene and other daily tasks. Following is a brief summary of her evaluation: TACE Center: Region IV, a project of the Burton Blatt Institute. Funded by RSA Grant # H264A080021. © 2012 49 LV Letter Example 2 (cont. 2) With her current eyeglasses, XXX’s vision measured at OD 10/100 (20/200) and OS 10/40 (20/80). Reading measured at 2.5 M (large print material size). Pupil reactions were minimal and eye movements were full. Visual fields by confrontations/Amsler grid showed a large dense central scotoma in the right eye and a smaller area of metamorphopsia centrally in the left eye, with periphery full to finger counting in both eyes. Additional findings were consistent with the diagnosis. TACE Center: Region IV, a project of the Burton Blatt Institute. Funded by RSA Grant # H264A080021. © 2012 50 LV Letter Example (cont. 3) Various low vision aids were demonstrated. We also demonstrated and instituted a course of eccentric viewing training. Best response to low vision aids were: 4.0X (brand) LED lighted stand magnifier for reading which allowed 1.0 M print (newsprint). We also demonstrated a 4.0X LED hand magnifer for portability. For glare issues, a medium plum sun filter (NoIR U81) was recommended. We plan to see XXX for additional evaluation and training, at which time we will demonstrate CCTV’s and other low vision aids. Thank you for allowing us to share in the care of this delightful woman. If there are questions, please feel free to contact us.
