Purpose:The objective of the study is to compare the frequency of Demodex on the eyelash follicle of patients with rosacea and referents without rosacea or ophthalmological disorders.Methods:This is a comparative, open, observational, and cross-sectional study that included 41 patients diagnosed with rosacea and 41 referents without rosacea diagnosis or ophthalmic alterations. The individuals underwent a slit-lamp examination in which two eyelashes per eyelid were removed with fine forceps. The presence of Demodex was sought by direct visualization under a light microscope. The results were expressed as “positive” when at least one mite on one lash was found and “negative” when no mite was identified. Chi-square test was used to compare the presence of mites in both groups.Results:Eighty-two study individuals (45 females and 37 males) were included, of which 41 patients were diagnosed with rosacea and 41 were without rosacea or ophthalmic alterations. The average mean age was 37 years with a minimum of 19 and a maximum of 87 years. Of the 41 patients with rosacea, 31 had erythematotelangiectatic rosacea and 10 had papulopustular rosacea. There were no patients with phymatous or ocular rosacea. The presence of Demodex was found in 32 patients: 24 patients with rosacea diagnosis (16 of the erythematotelangiectatic subtype and 8 of papulopustular subtype) and 8 patients without rosacea or ophthalmic alterations (P ≤ 0.001).Conclusion:Rosacea was found to be a statistically significant risk factor for Demodex infestation in eyelashes, irrespective of age and sex, with a higher prevalence in papulopustular variety.

Purpose: We describe the efficacy of lateral transorbital canthopexy using a silicone tube in managing severe paralytic ectropion. Methods: Patients with paralytic ectropion involving at least two-third of lower eyelid length and scleral exposure of 3 mm or more were considered. A silicone prosthetic was inserted during canthopexy. Results: Lateral transorbital canthopexy using a silicone tube was performed on 10 eyelids in nine patients. All patients had corneal surface abnormalities. Scleral exposure resolved completely in three cases. At 8-month follow-up, residual scleral exposure of 1 mm and 2 mm persisted in n = 6 and n = 1 cases, respectively. Conclusions: Lateral transorbital canthopexy using a silicone tube is an effective therapeutic option for paralytic ectropion, facilitating both functional and cosmetic results that proved durable over time.

La celulitis orbitaria es una inflamación infecciosa por detrás del tabique orbitario. Se destaca la infección bacteriana como la causa más común y Acinetobacter baumannii es infrecuente en esta patología. Presentación del caso: Paciente femenina de 54 años de edad, quien presentó dolor ocular derecho progresivo y proptosis. Se dio manejo intrahospitalario por diagnóstico de celulitis orbitaria en una clínica de segundo nivel de oftalmología, y después de 20 días de hospitalización, presentó evolución tórpida, razón por la cual se refirió a nuestro centro, donde se detectó crecimiento de A. baumannii. Discusión: La estancia intrahospitalaria de la paciente previa al ingreso en nuestro centro, asociada al antecedente de diabetes mellitus, representan los factores de riesgo más importantes para esta infección. Conclusión: A. baumannii, a pesar de ser un patógeno infrecuente asociado a la celulitis orbitaria, no debe excluirse del diagnóstico debido a la gravedad de las secuelas a las que se asocia.

Se describe el caso clínico sobre un tumor de estirpe histológica poco frecuente en cuanto a su localización, en un paciente de sexo femenino de 18 años de edad, quien inició con un nódulo eritematoso y doloroso en el párpado superior derecho, que se trató de forma conservadora, con buen resultado terapéutico; sin embargo, posterior a 1 año de evolución recidivó en el mismo sitio, por lo que se realizó biopsia. El reporte histopatológico fue un leiomioma epitelioide. Los párpados pueden ser el sitio de desarrollo de tumores poco comunes, en la mayoría de los casos estromales. La conducta terapéutica ante un tumor palpebral exige biopsia y análisis histopatológico para establecer el diagnóstico y tratamiento correctos.

Introduction: Orbital cellulitis is an infectious inflammation posterior to the orbital septum, with bacterial infection standing out as the most common cause. Acinetobacter baumannii is an uncommon cause of this pathology. Case Presentation: This is a 54-year-old female who presented progressive right ocular pain and proptosis. She received treatment under hospitalization for a diagnosis of orbital cellulitis in a secondary health center, and after 20 days of hospitalization, she presented a torpid evolution, which resulted in referral to our center, where A. baumannii was detected in cultures. Discussion: The patient's hospitalization prior to admission to our center, associated with a history of diabetes mellitus, are the most important risk factors for this infection. Conclusion: A. baumannii, despite being an infrequent pathogen associated with orbital cellulitis, should not be excluded from the diagnosis considering the severity of the sequelae to which it is associated.
