Descemets stripping automated endothelial keratoplasty (DSAEK) for the treatment of endothelial dysfunction offers several advantages over standard penetrating keratoplasty (PKP)1,2,3. By removing only Descemets membrane and dysfunctional endothelium, and retaining healthy portions of the individuals cornea, DSAEK gives more rapid visual recovery and preservation of the corneas biomechanical properties and integrity4,5. In addition, it provides superb vision in most individuals by reducing higher-order aberrations and improving corneal transparency6,7,8,9, resulting in less graft rejections than PKP9,10,11,12, and leading to a favourable long-term graft survival rate up to 85C87% at 5 years10,11. However, endothelial cell denseness (ECD) decreases after DSAEK as with eyes after PKP, which leads to endothelial dysfunction actually without graft rejection13,14. Therefore, to prolong graft survival and maintain good long-term vision after DSAEK, postoperative endothelial cell loss is an important issue that has to be tackled. ECD decreases over time after corneal transplantation15,16,17,18, and risk factors for postoperative E7080 tyrosianse inhibitor endothelial cell loss after PKP include donor age, recipient age, graft diameter, lens status, the presence of glaucoma, graft rejection, and peripheral corneal diseases18,19,20,21. However, the factors influencing endothelial cell loss after DSAEK are still poorly recognized. ECD rapidly decreases in some individuals after DSAEK, with no apparent intra- or postoperative complications. Recently, we noticed a rapid postoperative ECD decrease in some individuals with severe pre-existing iris damage, whereas the ECD decrease was minimal in individuals with a healthy iris. Therefore, we hypothesized that iris damage can lead to quick E7080 tyrosianse inhibitor endothelial cell loss after DSAEK. In this study, using Cox proportional risk regression and multiple linear regression, we evaluated potential factors that might be related to the risk of corneal graft failure and postoperative lower ECD, focusing especially within the pre-existing iris damage status. Results Patient Demographics Table 1 shows the demographics of the recipients, the donors of DSAEK graft, and intra- and postoperative characteristics. The mean age of the recipients was 69.7??12.1 years old. Pre-existing iris damage score was identified based on its severity from preoperative slit-lamp microscopy findings as follows: 0, no iris damage; 1, iris damage limited E7080 tyrosianse inhibitor to only one quadrant; 2, iris damage in two quadrants; 3, iris damage in three quadrants; and 4, iris damage in four quadrants (Fig. 1). E7080 tyrosianse inhibitor Pre-existing iris damage scores were 0 in 104 eyes, 1C2 in 89 eyes, and 3C4 in 31 eyes. Graft diameter had been determined by doctors, predicated on the sufferers corneal size, and 8.0?mm size was many common diameter in today’s study. Solitary DSAEK was performed Rabbit Polyclonal to F2RL2 in 143 eye and simultaneous cataract and DSAEK surgery was performed in 82 eye. Intraoperative iris harm happened in 27 eye of 27 sufferers, which was thought to be an independent aspect in E7080 tyrosianse inhibitor the pre-existing iris harm. Postoperative rebubbling was performed to take care of postoperative dual chamber, graft dislocation or graft detachment. Open up in another window Amount 1 Iris harm scoring strategies.Iris harm (light arrows) was scored predicated on preoperative slit-lamp microscopy and iris photo using infrared light the following: 0, zero iris harm; 1, iris harm limited to only 1 quadrant: 2, iris harm in two quadrants: 3, iris harm in three quadrants: 4, iris harm in four quadrants. Intraoperative iris harm was regarded and assessed as you of individual elements.
