Purpose:
Our purpose was to assess recipient peripheral corneal thickness as predictive factors for corneal endothelial cell density after penetrating keratoplasty
Setting:
: Seoul St. Mary's Hosptial, Seoul, Korea
Methods:
Twenty eyes showing keratoconus (group I, with sufficent recipient endothelial cell density) and twenty eyes showing bullous keratopathy(group II, with insufficent recipient endothelial cell density) were included in this retropsective study. The endothelial cell density, and four sites of peripheral corneal thickness after PKP was assessed for 1, 3, 6, 12 months
Results:
There was changes of corneal peripheral thickness in group I but there was significantly thinning in peripheral corneal thickness in group II comparing preoperative thickness in spite of central corneal enthelial cell densiy respectively(p<0.05) In group II patients, central endothelial cell density was much decreased comparing to group I in postoperative 12 months( gropu I ; 30.2% vs group II ;54.2%)
Conclusions:
This study shows the central corneal endothelial cells move toward pheriperal area to compensate the endothelial cell density after keratoplasty and this is the one of the possible reasons why the central endothelial cell density was much more loss in bullous keratopathy patients.
