ABSTRACT

PURPOSE: To review the incidence, resistance patterns, and management of bacterial keratitis during the past 4 years. METHODS: We retrospectively reviewed the clinical records of microbiological isolates from patients with a clinical diagnosis of bacterial keratitis. RESULTS: A total of 159 patients were analyzed, and 102 microorganisms were isolated from 129 cultures. In these cultures, 23.7% of the microorganisms were gram positive, 60.8% were gram negative, and 15.5% were fungi. Pseudomonas aeruginosa was the most common bacteria (9.2%), followed by Serratia marcescens (4.4%) and Staphylococcus aureus (4%). Resistance to fluoroquinolones and aminoglycosides was found to be 23.1% and 53.1% in gram-positive and 2.8% and 13.9% in gram-negative bacteria, respectively. Resistance to ceftazidime against gram-negative bacteria was 13.9%. No resistance to vancomycin was observed. CONCLUSIONS: A high resistance rate to aminoglycosides and fluoroquinolones was observed in gram-positive bacteria. We concluded that fluoroquinolones or aminoglycosides may not be suitable for initial monotherapy in patients with severe bacterial keratitis.

ABSTRACT

Las úlceras corneales se incluyen dentro de un grupo heterogéneo de lesiones oculares, las cuales pueden ser de gravedad variable. Cuando los pacientes no responden al tratamiento, incluyendo incluso el trasplante corneal, se crea la necesidad de explorar otras alternativas. Presentamos el caso de un paciente que sufrió una salpicadura ocular del contenido de una batería de automóvil por accidente. Esta lesión corneal, fue refractaria al tratamiento farmacológico e incluso quirúrgico. Tras cuatro años de persistencia de la úlcera corneal, se inició un tratamiento tópico con insulina 50 UI/ml. Se observó mejoría de forma evidente y actualmente el paciente ha recuperado completamente el epitelio corneal. Hoy en día, las evidencias disponibles del uso tópico de la insulina para el tratamiento de las úlceras corneales se centran en pacientes diabéticos. En los pacientes no diabéticos, la evidencia se limita a una serie de casos de úlceras neurotróficas corneales y al caso de un paciente que presentó un defecto epitelial persistente después de la resección de un neurinoma. Este caso, presenta la experiencia de uso de una formulación magistral de insulina oftálmica con eficacia y ausencia de toxicidad en un paciente no diabético con una úlcera corneal post-cáustica resistente al resto de tratamientos


Corneal ulcers are included in a heterogeneous group of eye injuries.

This corneal lesion was refractory to both surgical and pharmacological treatment. After four years of a persistent ulcer, insulin topical treatment 50 IU/mL was started. Improvement began to be observed and currently the patient has completely recovered the corneal epithelium. Nowadays, evidence of the topical insulin use for the treatment of corneal ulcers is higher in diabetic patients. In non-diabetic patients, evidence is restricted to a series of cases of neurotrophic corneal ulcers and a case report of a patient who presented a persistent epithelial defect after resection of a neurinoma. This case presents the experience of using an insulin drop formulation with effectiveness and absence of toxicity in a patient non-diabetic with a post-caustic corneal ulcer

ABSTRACT

Corneal ulcers are included in a heterogeneous group of eye injuries. When  patients do not respond to treatment, including even corneal transplant, other  alternatives need to be explored.We present a case of a patient who suffered an accidental spillage from the  contents of a car battery. This corneal lesion was refractory to both surgical and  pharmacological treatment. After four years of a persistent ulcer, insulin topical  treatment 50 IU/mL was started. Improvement began to be observed and  currently the patient has completely recovered the corneal epithelium.Nowadays, evidence of the topical insulin use for the treatment of corneal ulcers  is higher in diabetic patients. In non-diabetic patients, evidence is restricted to a series of cases of neurotrophic corneal ulcers and a case report of a patient who  presented a persistent epithelial defect after resection of a neurinoma. This case  presents the experience of using an insulin drop formulation with effectiveness  and absence of toxicity in a patient nondiabetic with a post-caustic corneal ulcer.
