Measurements of the Ciliary Body Structures of Healthy Individuals with Different Eye Lengths
Introduction. Dimensions of the ciliary body structures can be objectively estimated using an ultrasound examination, optical coherence tomography, as well as by the method of transillumination. Purpose. To study the sizes of structures of a ciliary body depending on eye length in healthy patients. Materials and methods. Under observation were 49 people (98 eyes) without visible pathological changes in the anterior segment of the eye. All patients were divided into three groups, depending on the anterior-posterior size of the eye. In all cases, infrared transpalpebral transillumination and ultrasound examination of the anterior segment of the eye were performed. Results. In patients with an eye length of 2022.9 mm, the width of the pars plana of the ciliary body averaged 3.1 mm, with an eye length of 2324.9 mm 4.1 mm, with an eye length of 2535 mm 5 mm. The width of the pars plicata of the ciliary body in the first group was 1.9 mm, in the second group 2.0 mm, and in the third group 2.0 mm. Conclusion. A relationship was found between the width of the pars plana of the ciliary body and the length of the eye. So, in healthy individuals with an eye length of 2022.9 mm, the width of the pars plana of the ciliary body averaged 3.1 mm, with an eye length of 2324.9 mm 4.1 mm, with an eye length of 2535 mm 5 mm. There is a tendency to an increase in the size of the part plicata of the ciliary body in healthy individuals with a longer eye length.
