A complicated anterior segment increases graft failure and dislocation in eyes undergoing Descemet’s stripping automated endothelial keratoplasty (DSAEK). Francis Char DeCroos, MD Derek W.

Purpose • To investigate the relationship between DSEK graft dislocation and failure in eyes with a prior diagnosis of glaucoma and a complicated anterior segment (including peripheral anterior synechiae or PAS, narrow angles, or a shallow anterior chamber). J. J. Kanski, Clinical Ophthalmology: A Systematic Approach, 2007
Hypothesis • Challenges in glaucomatous eyes • Increased rate of PAS1 • Increased rate of narrow angles or shallow AC2 • Difficulty in obtaining appropriate AC air fill3 • Manipulation with indwelling shunt • 1.8X chance of increased rejection4 1. Lee, Kor J Ophthalmol, 2006. 2. Bonomi, Ophthalmol, 2000;3. Ide, Open Ophthal J, 2009; 4. Price, Br J Ophthalmol, 2009.
Methods • Retrospective case-control study • Cases: Prior diagnosis of glaucoma • No history of incisional glaucoma surgery • Prior trabeculectomy and/or aqueous shunt(s) • Controls: No prior diagnosis of glaucoma • Include only first DSAEK in any eye
BCVA *p<0.05 at all evaluated time points
IOP *p<0.05 at 180 day time point only
Glaucoma Subgroup Analysis Glaucoma n = 96 Uncomplicated Anterior Segment n = 69 Complex Anterior Segment n= 27 PAS n = 8 Narrow Angle or Shallow AC n = 7 PAS + Narrow Angle or Shallow AC n = 12
Conclusions • Complex Anterior Segment • Risk factor for graft dislocation • Risk factor for graft failure • Should prompt meticulous post operative surveillance
