The aim of the work was to establish predisposing factors leading to microbial contact lens-related keratitis in children, demographics of patients, clinical and microbiological features, clinical outcomes at a tertiary eye care center in Lithuania.
Methods. A retrospective analysis was performed of case histories of all patients who were diagnosed with CL-related keratitis from 2007 in Children‘s Hospital, Affiliate of Vilnius University Hospital Santariskiu Klinikos. The following data were analyzed: patient age, gender, hospitalization time from the begining of the disease, risk factors of CL wearing, severity of the lesions, vision acuity in the beginning and going home, vision improvement during treatment, if the swabs and culture growth was made, what causative agent was found, what was the treatment and duration of hospitalization.
Results. 150 patients have been hospitalized at Children‘s Hospital, Affiliate of Vilnius University Hospital Santariskiu Klinikos, Eye Care department with the diagnosed various keratitis during a period from 2007 to 2012. 13 of them were CL associated keratitis. That is 8,67 percent of all keratitis, treated in the hospital, and 0,21 percent of total hospitalized patients number during pending period. The most often risk factors for keratitis were overnight CL use (4 cases), use of lenses while swimming (3 cases), inadequate hygiene (2 cases). Ethiological agent wasn‘t identified in 6 cases. Staphylococcus epidermidis was found in 4 cases, in 1 case in combination with Bacteroides ureolyticus. Streptococcus pneumoniae was the causative agent in 1 case. Gram-positive cocci were found in 1 sample. Candida glabrata, Aspergillus spp. and anaerobic gram-positive bacilli Propionbacterium spp. were isolated in 1 sample.
Conclusions: 1. 8,67 percent of all keratitis in children, treated in Children‘s Hospital, Affiliate of Vilnius University Hospital Santariskiu Klinikos, Eye Care department, from January, 2007, untill August, 2012, were associated with contact lenses wearing. 2. The most often risk factors for CL-related keratitis were overnight CL use, use of lenses while swimming and inadequate hygiene. 3. The culture growth was positive and etiological agent was identified in 53,85% cases. Staphylococcus epidermidis was the most common pathogen. Fungal pathogen was the causative agent in one case. 4. Visual acuity improved to 0,7 and more in 92,3% cases, in 1 case visual acuity remained very bad even after treatment.
