Trata-se de um caso de ceratite bilateral e simultânea por Acremonium relacionada ao uso intermitente e sem respeitar a lateralidade do uso de lentes de contato gelatinosas. Houve diagnóstico tardio, apresentando resistência a anfotericina B e hipópio persistente, com resposta positiva a natamicina tópica. Além da forma incomum de apresentação, não houve histórico de trauma ou contato com material vegetal, associado à maioria dos casos de ceratite por fungos filamentosos.

Objective: To investigate the correlation between phenol red test and Schirmer tear test on tear quantification together with a questionnaire to detect symptoms of dry eye. Methods: A total of 49 patients were enrolled at this study. Each participant had its eyes examined by the two tests.The dry eye symptoms were evaluated by a total of 5 questions.The data were collected and analysed by Kappa statistical method to check the concordance between the tests. Results: A sum of 65.3% of […]

Objective: Describe the epidemiological profile of cornea donors in the state of Goiás. Methods: We used a random sample of 793 records calculated by the formula of Leslie Kish (Epi Info 7) taking into account a total of 3,093 records from January 2006 to August 2015. The data was analyzed using the Statistical Package for Social Sciences (SPSS) and the results were described using proportions, central tendency and dispersion measures. Comparisons between categorical variables were made using the chi-square test […]

Objective: To determine if the change in the shape of the corneal epithelial removal in photorefractive keratectomy (PRK), from circular to oval shape, modifies the recovery of the postoperative visual acuity (VA). Methods: Forty-three(43) patients subjected to bilateral simultaneous PRK were prospectively evaluated. Randomly for each patient, one eye underwent epithelial removal in circular shape and the other in oval shape. On the sixth day of postoperative period (D6) the follow items were recorded: the subjective comparative perception, informed by […]

Objective: To evaluate the occurrence of a mutation in candidate genetic loci and its relation with keratoconus in patients treated in Brazil compared to healthy volunteers, through analysis of single nucleotide polymorphism in the DOCK9 gene. Methods: In this clinical study, 108 participants were evaluated, including 46 keratoconus patients and 62 healthy volunteers (controls). DNA samples were extracted from collected blood from keratoconus patients and controls. The genotyping of the single nucleotide polymorphism rs7995432 in the DOCK9 gene was determined […]

This article presents a review of the principles and clinical applications of the Scheimpflug principle in the anterior segment imaging. By providing a three-dimensional image of the anterior segment, this technology provides elevation and curvature data of the anterior and posterior surfaces of the cornea, pachymetric mapping, the total refractive power of the cornea and the anterior segment biometry. For the refractive surgery sub-specialty, this approach improves the ability to identify cases at risk of ectasia, as well as the […]

Objective: Investigate in which eye banks in Brazil the HTLV I and II is used as exclusion criteria for cornea. Nowadays Brazilian Legislation, through Law nº 9.434/97 and Ordinance 2600/09 determines that for each donation, laboratory screening tests of high sensibility must be done mandatorily for detection of markers of infectious diseases transmissible by blood: Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HbsAg), Antibody of the Hepatitis B Virus (AntiHBs), Antibody of total Hepatitis B Virus (total Anti- HBc) and […]

The corneal cross-linking has been used in order to reduce and stabilize the progression of ectatic diseases through its effects on the biomechanics of the cornea. Different protocols are being conducted worldwide to expand its indications as well as its use at different ages, different stages of the disease, combinations with other techniques, besides the utilization for non-ectatic diseases. There is still no consensus on the indications of the cross-linking procedure, but the results published in the literature show significant […]
