This process results in the formation of posterior staphyloma, which justifies the term "degenerative". The excessive axial growth causes a narrowing of the retina and choroid and a weakening of the sclera. Discussionĭegenerative myopia entails diverse ocular modifications. It’s possible to notice appearence of discrete lacquer crack in papillomacular bundle. The progression of lacquer cracks and focal hemorrhages can be seen. Fundus photography is shown below ( Figures 1A and 1B).įigure 2: A) 2 years after Figure 1A. The ophthalmological examination revealed best corrected visual acuity of 20/100 (-26,50 sph.-0,75 Cyl. ResultsĪ 33-year-old female patient, from Salvador (BA)–Brazil, arrived at the Ophthalmology center of the São Rafael Hospital presenting visual impairment in 2011. Methodsĭata were collected through the analysis of a patient’s medical history at Hospital São Rafael and Hospital Complex Professor Edgar Santos. The aim of this study is to report the case of a patient with degenerative myopia, highlighting the progression of pathological findings in two years. The degenerative myopia is a medical condition of great relevance due to its large physical and socio-economic impact, as it may result in irreversible loss of bilateral central vision in workingage people. These changes result in visual impairment, changes in contrast sensibility, lower dark adaptation, visual field changes and electrophysiological changes. The progressive expansion of the eyeball leads to the formation of posterior staphyloma and degenerative changes of the sclera, choroid, Bruch's membrane, retinal pigment epithelium and neural retina. Patients with high myopia are more likely to develop degenerative conditions that range from lacquer cracks to neovascular membrane formation and retinal detachment. This disease is a subtype of high myopia, which is characterized for refractive values lower than -6 diopters and axial length greater than 26,5 mm. The etiological mechanisms are unknown, but the influence of genetic and environmental factors has been increasingly recognized. The accelerated ocular growth is followed by scleral stretching, that will result in the formation of the characteristic findings of degenerative myopia. It is a condition characterized by the progressive expansion of the eyeball axial length which is not stabilized during the adulthood, causing a progressive degeneration. The degenerative myopia is often associated with blindness and the etiology is still not clear. Conclusions: Within two years, it was observed decreased visual acuity, as well as appearance and worsening of some evidence of progression of the disease such as lacquer cracks and subretinal hemorrhage. Methods and Findings: Data were collected through the analysis of a patient’s medical history at Hospital São Rafael and Hospital Professor Edgar Santos. that has progressed within two years with decreasing visual acuity and the appearance of lacquer cracks in both eyes. ![]() This article aims to report the evolution of the pathological findings in the fundoscopic exam in a 33-year-old woman with degenerative myopia. It is characterized by a progressive expansion of the eyeball without stabilization of the axial length in adulthood, causing a progressive degeneration that is often associated with retinal changes that can cause severe and irreversible visual impairment.
