Purpose:
|
This study was conducted to evaluate the role of microbiologic smear and culture and corneal confocal scan in the diagnosis and management of patients with infectious keratitis.
|
|
Methods:
|
Patients with clinical diagnosis of infectious keratitis admitted to the Labbafinejad medical center (2009 to 2011) were included in the study.The results of smear and culture and confocal scan, and the rate of response to treatment were statistically analyzed.
|
|
Results:
|
110 patients with microbial keratitis were evaluated. The mean age of patients was 58.8 years and 63% were male. Smear, culture and confocal scan results were not available to patients’ physicians in 28, 30 and 14 cases, respectively. Smears were positive in 8 cases (7 bacterial and 1 fungal). Cultures were positive in 5 patients; 4 of which had bacterial and 1had fungal isolates. Confocal scan revealed the pathogenic agent in 20 cases and ruled out the presence of fungal and acanthamoeba structures in 7 cases.
|
|
Conclusion:
|
Corneal smear and cultures have limited value in the diagnosis and subsequent management of infectious keratitis because of use of wide spectrum antibiotics before microbiologic analysis but Confocal scan seems to be a safe and efficient method. Therefore, modifying diagnostic traditional approaches in cases with infectious keratitis is necessary.
