Abstract
Purpose : To review the leading indications for penetrating keratoplasty (PK) at Mettapracharak Eye Center from January 2002 to January 2007
Design : Retrospective, non-comparative study
Methods : Medical charts of all the patients who had undergone penetrating keratoplasty (PK) at Mettapracharak Eye Center, Nakornpathom, Thailand, from January 2002 to January 2007 were retrospectively reviewed. The indications for penetrating keratoplasty (PK) were categorized into eight diagnostic groups, which included
1. Corneal scars 2. Bullous keratopathy 3. Corneal ulcer 4. Corneal dystrophy
5. Corneal ectasia 6. Regrafts 7. Chemical burns and 8. Other causes
Results : The leading indication categories for PK were
1. Bullous keratopathy (25 cases, 40.3% of all indications); PBK 22 cases (88% of all Bullous keratopathy), ABK 2 cases (8% of all Bullous keratopathy), and Bullous keratopathy after Trabeculectomy 1 case (4% of all Bullous keratopathy).
2. Corneal ulcer and its complication except corneal scar eg. impending perforation (13 cases, 20.96%).
3. Corneal scar (9 cases, 14.5%). The major cause of corneal scarring was post trauma (4 cases 44.4% of total corneal scar). The second cause was post infection corneal scar (3 cases 33.3% of total corneal scar). Other conditions cause (2 cases 22.25% of total corneal scar).
4. Corneal dystrophy: Fuchsû endothelial dystrophy (7 cases, 11.3%).
5. Regrafts (3 cases, 4.8%).
6. Corneal ectesia : Keratoconus (3 cases, 4.8%).
7. Chemical burn 1 case (1.6%)
8. Other cause (ICE syndrome) 1 case (1.6%).
Conclusions : Bullous keratopathy was the most common indication for PK at our hospital. The sufficient eye donors would increase the rate of PK in corneal keratitis and prevent the loss of the patientûs eyes from evisceration and enucleation.
Abbreviations : PK = penetrating keratoplasty, BK= bullous keratopathy, PBK= pseudophakic bullous keratopathy, ABK = aphakic bullous keratopathy
