Resumen
LOPEZ HERNANDEZ, Silvia M. et al. Predisposing factors for therapeutic keratoplasty in patients with severe corneal ulcer. Rev Cubana Oftalmol [online]. 2019, vol.32, n.2 Epub 15-Sep-2019. ISSN 1561-3070.
Objective:
Describe the predisposing factors for therapeutic keratoplasty in patients with severe corneal ulcer.
Methods:
A descriptive cross-sectional study was conducted of a sample of 64 patients admitted to the Cornea Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from January 2011 to December 2014.
Results:
The sample was characterized according to the following sociodemographic variables: age (mean of 51.3 ± 2.9); sex (67.2 % were male), and risk age groups (83.3 % were farmers and 74.6 % were urban). The most common traumas were caused by foreign bodies (26.6 %), contact lenses (9.4 %) and chemical burns (6.3 %). 82.8 % of the patients received treatment during 22.5 ± 4.6 days before admission and 6.9 days before keratoplasty. Microbiological results revealed 88.2 % positivity. Filamentous fungi and bacteria were the most common isolates.
Conclusions:
Male sex, farming, outpatient treatment for 18 to 27 days before keratoplasty and filamentous fungi as etiological agents, are considered to be risk factors for therapeutic keratoplasty in corneal ulcers.
