ABSTRACT
As one of the main causes of low vision and blindness in the world, high myopia has become increasingly serious and caused heavy economic and social burden.However, its pathogenesis is complex and has not been fully clarified yet.In recent years, with the continuous progress of biological technology, proteomic technology has been used to find differentially expressed functional proteins in animal models and tissues of high myopic patients in order to obtain specific biological markers related to high myopia, and to provide new insights for exploring the pathogenesis, diagnosis methods and treatment of high myopia.In this article, the clinical characteristics of high myopia, the research content and strategies of proteomics, the research progress of proteomics in high myopia studying eye tissues of model animals and the blood, lens and aqueous humor of patients were reviewed, the outstanding advantages and achievements of proteomic technology in the study of high myopia were analyzed, and the pathological mechanism of high myopia was explored from the perspective of functional proteins, which would provide a theoretical basis for the development of specific molecular drugs with therapeutic value.
ABSTRACT
Abstract The presence of retinal myelinated nerve fibers is not a rare finding during routine examinations, and it is usually a benign and isolated finding. However, in some rare cases, it can be associated with other ophthalmological conditions. We describe a case of a patient with the triad myelin nerve fibers, myopia and ambliopia, which configures the Straatsma Syndrome.
Resumo A presença de fibras de mielina é um achado comum durante exames oftalmológicos de rotina. Na maior parte das vezes, tem caráter beningno e é um achado isolado. No entanto, em alguns raros casos, a presença de mielinização pode estar associada a outras condições oftalmológicas. Descrevemos um caso de paciente com a tríade presença de fibras nervosas retinianas mielinizadas, miopia, e ambliopia, configurando a síndrome de Straatsma.

ABSTRACT We report a case of a 49-year-old female who presented to the emergency department with blurred vision and vomiting, hours after taking two tablets of 250 mg of acetazolamide. The anterior chamber was bilaterally flat, with normal intraocular pressure in both eyes. An ultrasound biomicroscopic (UBM) examination showed bilateral ciliary effusion and complete appositional angle closure in all quadrants. Acetazolamide-induced bilateral angle closure was diagnosed. Steroid and cycloplegic therapy were initiated, and acetazolamide was discontinued. The following day, the anterior chamber had regained its volume without substantial change in the effusion size. Three weeks later, complete resolution of the ciliary effusion was verified by means of a third UBM scan.
RESUMO Relatamos um caso de uma mulher de 49 anos que se apresentou ao departamento de emergência informando visão borrada e vômitos, horas após ter tomado dois comprimidos de 250 mg de acetazolamida. A câmara anterior era bilateralmente plana com pressão intraocular normal em ambos os olhos. Um exame de biomicroscopia ultrassônica (UBM) mostrou efusão ciliar bilateral e fechamento completo do ângulo aposicional em todos os quadrantes. O bloqueio angular bilateral induzido por acetazolamida foi diagnosticado. O tratamento com esteróides e cicloplégicos foi iniciado e a acetazolamida foi descontinuada. No dia seguinte, a câmara anterior recuperou seu volume sem alterações substanciais no tamanho da efusão. Três semanas depois, a resolução completa da efusão ciliar foi verificada por meio de uma terceira biomicroscopia ultrassônica.

Abstract This article reports two cases of Straatsma Syndrome, a rare disease, emphasizing its clinical features that inclued myopia, strabismus and amblyopia associated with persistent myelinated fibers in the retina. Ophthalmic examination, color retinography and optical coherence tomography were performed.
Resumo Este artigo relata dois casos de síndrome de Straatsma, uma doença rara, enfatizando suas características clínicas que incluem miopia, estrabismo e ambliopia associada a persistência de fibras de mielina na retina. Foram realizados exame oftalmológico, retinografia e tomografia de coerência óptica.
