Observational Study of Vision Improvement in Late Stage Dry AMD Patients

Observational Study of Vision Improvement in Late Stage Dry AMD Patients by a Low Vision Aid Device

The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device.

The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device. Patient records for patients with at least 12 months follow-up will be analyzed to determine measures of vision improvement including best spectacle-corrected distance and near visual acuity. Analyses will include descriptive statistics and correlation between outcomes and baseline characteristics.

Inclusion Criteria:

1. - Male or female
2. - Any race
3. - Patient is at least 50 years old
4. - Patient has diagnosed late stage dry age-related macular degeneration in one or both eyes.
5. - Treated eyes were pseudophakic at the time of treatment.
6. - Patient had moderate to severe baseline vision impairment with best spectacle-corrected distance visual acuity (CDVA) of 20/63 or worse (decimal = 0.317 or less; logMAR greater than or equal to 0.50) in the treated eye(s).
7. - Patient CDVA records are available at baseline and at 12 month post-treatment.

Exclusion Criteria:

1. - Corneal disease or disorder in either eye.

2. - Increased intraocular pressure (above 20 mm Hg), glaucoma or history of glaucoma.

3. - Presence or history of any other condition or finding that, in the opinion of the investigator, makes the patient unsuitable for retrospective observational study.
