RESUMO

BACKGROUND AND PURPOSE: The purpose of this study is to compare two alternative methods of collecting and transporting media for the diagnosis of corneal ulcers, as not all clinical settings have conventional culture materials and transport media available. METHODS: In this open-label, prospective, comparative, and randomized study, patients with clinical suspicion of infectious keratitis with high risk of loss of vision had corneal specimens collected using two methods and transport media: Eswab scraping with Amies transport medium and 23-gauge needle scraping in BACTEC Peds broth. The order of each collection method was randomized. The samples were processed by standard methods, comparing the positivity frequencies for both by parametric and nonparametric tests, according to normality criteria. RESULTS: Corneal infiltrates from 40 eyes of 40 patients were analyzed. Culture positivity rate was 50% for Eswab and 35% for 23-gauge needle (P=0.258). The overall growth rate of the two methods combined was not higher than with the swab alone. The results obtained with a swab were not influenced by the collection sequence (P=0.112); however, the positivity rate was significantly higher when the sample taken with the needle was performed first (P=0.046). CONCLUSIONS: The single sample Eswab method of collection and transportation for the diagnosis of high risk corneal ulcers is a valid alternative and can be used in cases in which, for various reasons, there is no access to the full set of traditional culture materials.

RESUMO

A 52-year-old patient with multiple cardiovascular risk factors referred for unilateral, acute, and painless visual loss. In the fundoscopic image there was significant papillary inflammation with tortuosity at this level and haemorrhages. Ophthalmological examination showed papillary inflammation, macular oedema, and involvement in retinal inner layers. The control fluorescein angiography and optical coherence tomography angiography showed areas of central and peripheral ischaemia. Given the clinical findings and background of the patient, the diagnosis of Purtscher-like retinopathy was reached and treatment with intravitreal dexamethasone was decided. Purtscher-like retinopathy is a rare entity that occurs in patients with multiple systemic pathologies, but without a traumatic background, which differentiates it from Purstcher's retinopathy. The diagnosis and early intervention are important in the prognosis. There are no therapeutic protocols, but good results have been obtained with intravitreal therapy with dexamethasone.
