[Scanning electron microscopy results of the vitreous body in asteroid hyalosis].

Purpose: To evaluate the structure of vitreous body in asteroid hyalosis by low vacuum scanning electron microscopy.

Material And Methods: The material of the study was samples of the vitreous body obtained from 7 patients aged from 62 to 72 years with vitreomacular traction syndrome during vitrectomy. In all cases, clinical manifestations of asteroid hyalosis (the presence of multiple point-like echo-positive inclusions) were identified during the preoperative examination.

[Structural features of the vitreous body in asteroid hyalosis].

Purpose: To analyze intravital structure of the vitreous body in asteroid hyalosis using digital ultrasound imaging.

Material And Methods: The study included 64 patients (128 eyes) aged 62 to 73 years with opacities in the vitreous body characterized as asteroid hyalosis.

Results: The macrostructure of the vitreous body was evaluated based on the results of digital ultrasound imaging.

[Asteroid hyalosis].

The article analyzes existing information on clinical and experimental studies of vitreous changes in asteroid hyalosis, historical aspects of how this condition was studied over the past hundred years, its occurrence and pathogenesis. Results of various studies were used to evaluate current understanding of the forms and elemental composition of phospholipid mineral sedimentation on vitreous structures and methods of its examination. The problem of intravital assessment of the condition of vitreous body was analyzed, and a method was suggested for studying the macrostructure of hyaloid tracts and the state of the vitreous body by means of digital ultrasound in patients with asteroid hyalosis.

[Clinical and morphological changes in the eye in Fabry's disease (a clinical case study)].

The article presents a clinical case of Fabry's disease accompanied by changes in the eye and gives detailed description of standard ophthalmological examination and results of some modern methods of assessing macro- and micro-structure of certain ocular tissues. Fabry's disease (also known as Anderson-Fabry disease, diffuse angiokeratoma of the body, hereditary dystonic lipidosis) is a progressive hereditary multi-systemic disease; more specifically, it is a progressive congenital defect in the metabolism of tissues of the human body. It is included in the list of orphan diseases.

[Three-dimensional acoustic analysis in diagnostics of structural and morphological changes of the eye in certain congenital pathologies].

Unlabelled: Changes in ocular anatomy and topography that occur due to congenital development anomalies are often of complex, composite nature. Such pathologies are accompanied by not only refractive errors, but also changes in eye's macrostructure. Careful analysis of the changes is necessary to better understand the clinical picture.
