Resumen
MARQUEZ FALCON, Adonis; CABANES GOY, Lidaisy; HERNANDEZ CASANOVA, Nisbeth y IZQUIERDO LOPEZ, Yoel. Incidence of Filtration Bullae-related Infections in Trabeculectomy Patients. Rev Cubana Oftalmol [online]. 2022, vol.35, n.4 Epub 01-Dic-2022. ISSN 1561-3070.
Purpose:
To determine the incidence of filtration bullae-related infections in patients undergoing trabeculectomy; as well as their clinical behavior.
Methods:
A longitudinal and retrospective descriptive study was performed. The universe was comprised of 1320 eyes with trabeculectomy and the sample consisted of 7 eyes with a diagnosis of infection related to the filtration bulla operated at the Villa Clara Ophthalmologic Center between January 2012 and December 2021.
Results:
The overall incidence of infection in the filtration bullae was 0.53%. The incidence of blebitis and blebitis-endophthalmitis was 0.15 % and 0.38 %, respectively. Males were the most affected and the average age was 64.7 years. In all cases, the infection presented late with a average age of 4.1 years. Fifty-seven point one percent had best corrected visual acuity at the onset of hand motion infection. Bacterial growth was reported in 57.1 %, coagulase negative staphylococcus was the most frequent germ. Infection control was achieved in 6 patients while 2/3 of them had no improvement of best corrected visual acuity at resolution of infection, all with blebitis-endophthalmitis.
Conclusions:
Infections related to filtration bullae are uncommon. They occur frequently years after filtering surgery and with poor visual acuity. Eyes with blebitis-endophthalmitis have poor visual recovery despite treatment.
