Bacterial corneal ulcers in pediatric patients. Algorithms of pharmacotherapy. Part II

Abstract

Part I of the article presents a review of publications highlighting current exogenous and endogenous risk factors contributing to the occurrence of bacterial corneal ulcers, laboratory diagnostic methods, clinical differential diagnostic features of bacterial corneal ulcers.
 A wide variety of objective symptoms characterizes the clinical picture of bacterial corneal ulcers. Still, objective differential diagnostic signs make it possible with a high degree of probability to assume the etiology of the disease during the first biomicroscopy and immediately begin etiotropic therapy, on the timing of which the outcome of the disease depends.
 Standard laboratory examination of patients with bacterial corneal ulcers includes the bacterioscopic and cultural examination of the contents of the conjunctival sac. However, the absence of etiotropic therapy while waiting for the results of microbiological research methods, which takes from 3 to 7 days, contributes to the rapid progression of the disease, the development of endophthalmitis, and corneal perforation, up to the loss of an eye in children. In this regard, treatment must be started immediately. Therefore, the choice of a drug is determined not only by the causative agent, proven laboratory but, first of all, based on clinical differential diagnostic signs of the disease.
 The traditional, undeniable approach to the conservative treatment of bacterial corneal ulcers is conventional etiotropic therapy using local and systemic antibacterial drugs. In addition, timely intensive specific drug therapy prevents the destruction of all layers of the cornea, and the use of metabolic drugs that improve regeneration and trophism promotes epithelialization of corneal ulcers.
 Attention should be given to the necessity and validity of the choice of antibacterial drugs for various etiological forms of bacterial corneal ulcers in children. An individual approach is a basis for effective antibiotic therapy in pediatric ophthalmology.
 The article presents an up-to-date review of publications and modern algorithms for treating bacterial corneal ulcers in children, the main causative agents of which are: Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Neisseria gonorrhoeae.
