The purpose of this study is to evaluate the postoperative clinical outcomes of the first 10 patients that underwent placement of an implantable miniature telescope (IMT) for end-stage age-related macular degeneration (ARMD) at the UC Davis Eye Center.
A retrospective analysis of the first 10 patients with end-stage ARMD who underwent IMT placement at the UC Davis Eye Center between 5/2012 and 7/2013 was performed. Visual acuities, intraocular pressures (IOPs), and specular microscopy were analyzed at the preoperative visit and postoperative month 3 and 6 visits. The frequency and number of occupational therapy visits and any postoperative complications were also evaluated.
The average age of patients undergoing IMT placement was 81.9 years. The average preoperative best spectacle-corrected visual acuities (BSCVA) in patients selected to undergo placement of the IMT was 1.443 logMar (20/550) vision. At postoperative month 3 and 6 visits, BSCVA improved to 1.210 (20/320) and 1.210 (20/320) with an average of 2 Snellen lines of improvement in BSCVA. Preoperatively, the mean IOP of these patients was 14, with mean IOPs of 12 and 12 at 3 and 6 months postoperatively. The average endothelial count of patients preoperatively was 2106 and the average endothelial count at the 6 month visit was 1758. The average number of occupational therapy visits that patients went to was 7 (range 2-10). In terms of postoperative complications, one patient had a fall with expulsion of the IMT.
The use of IMTs in selected patients suffering from end-stage age related macular degeneration appears to improve visual acuity.
