Context:
Early diagnosis of ocular infections following penetrating keratoplasty (PK)
facilitates the preservation of useful vision and furthermore prevents the
progression of intraocular spread. This largely depends on the initial clinical
presentation and preoperative extensive and laborious ancillary laboratory
investigations. Objectives of the Study: The aim of this research was to study
donor and recipient risk factors for post-PK ocular infections Population and Methods: This is an
interventional prospective study conducted in 34 patients who underwent PK
under peribulbar anesthesia from 2014 to 2016 at a tertiary based teaching
hospital. Eyes with posterior segment pathology excluded with the inclusion of
all other corneal disorders that caused opacification. Six patients developed
signs and symptoms suspicious of postoperative infections. Statistical analysis
performed with MS Excel software.
Results: The mean age was 53 (+/-18.04) years, ranging from 12 to 86
years with 24 (70.59%) males and 10 (29.41%) females. There were 24 (70.59%)
right eyes and 10 (29.41%) left eyes. The mean age was 63.97 (+/-16.08) years
among the donors. Six (17.64%) patients developed postoperative infections that
included one patient with Pseudomonas aeroginosa keratoconjunctivitis, two
patients with fusarium fungal keratitis and surprisingly, observed that failure
to establish growth in the remaining three cases. Positive microbial
identification by culture was possible only in three (8.82%) patients.
Conclusion: Confirming the microbial identification possible only in three
patients, and the other three cases revealed no growth even after one week of
incubation. The risk factors found among recipients were a vegetative injury,
dust fall, and eye rubbing, as well as taking a very hot bath. Graft clarity
restoration significantly improved after topical management with fortified
antibiotics and antifungal agents.
