Abstract
Purpose
To present the long-term results of therapeutic keratoplasty for microbial keratitis in moderate to advanced phases.
Methods
The medical records of 44 patients who underwent therapeutic keratoplasty for microbial keratitis at the ophthalmology clinic of a training and research hospital between June 2012 and March 2018 were reviewed in this retrospective study.
Results
Of the 65 patients that underwent TPKP, 44 eyes of 44 patients met the inclusion criteria and enrolled in this study. The most commonly found predisposing factor for keratitis was a history of trauma (n = 17, 38.6%), and most of them had occurred with a vegetative matter (n = 14, 31.8%). The most common clinically suspected cause was fungal (n = 17, 38.6%) followed by bacterial (n = 12, 27.3%). In 26 (59.1%) cases, the causative microorganism could not be proved with a microbial culture. The most common causative microorganism was Staphylococcus spp. (n = 4, 9.1%), followed by Fusarium solanii (n = 3, 6.8%). The mean follow-up time was 42 (range 12–54) months. At the last follow-up visit, anatomical success was achieved in 40 (90.9%) cases and the BCVA of more than half of the patients was over 1.0 (logMAR, n = 24, 54.5%). Most commonly seen complication was found to be secondary glaucoma (n = 19, 43.2%), followed by cataracts (n = 9, 34.6%) and graft rejection (n = 12, 27.3%).
Conclusions
TPKP offers a definitive solution in the management of microbial keratitis with high rates of anatomical and functional success. However, secondary glaucoma is the most common complication after TPKP, which was seen in almost half of the patients.
