Dimensions of ciliary body structures in various axial lengths in patients with rhegmatogenous retinal detachment
Journal Title: Офтальмологический журнал - Year 2017, Vol 0, Issue 6
Abstract
Background: Ciliary body size may be objectively assessed by ultrasound scanning and near-infrared transpalpebraltransillumination. Purpose: To investigate the dimensions of ciliary body structures in various axial eye lengths in patients with rhegmatogenous retinal detachment (RRD). Materials and Methods: This study included 35 RRD patients (35 eyes) with an intact fellow eye who were under observation. These were divided into three groups, based on axial length of the eye with RRD. All patients underwent near-infrared transpalpebraltransillumination (NIRTPT) and ultrasound scanning of the anterior eye. Results: In patients with axial length ranging from 20 mm to 22.9 mm, 23 mm to 24.9 mm, and larger than 25 mm, pars plana width was 3.4 mm, 4.16 mm, and 4.16 mm, respectively, whereas pars plicata width was 1.9 mm, 1.99 mm, and 2.0 mm, respectively, and pars plicata thickness was 0.75 mm, 0.75 mm, and 0.72 mm, respectively. Conclusions: A direct relationship exists between pars plana width and axial length, but pars plicata thickness and width do not depend on the axial length in eyes with RRD. There was no difference in pars plana width or pars plicata width between the eye with RRD and unaffected fellow eye. In the eye with RRD, the pars plicata thickness was thicker than that in the intact fellow eye, which may evidence the presence of intraocular inflammation.

Ocular hemodynamics in patients with stage I-IV keratoconus
Background. Keratoconus is a progressive dystrophic condition of the cornea. Dystrophic changes in keratoconus are observed in the connective tissues of the sclera, drainage area, and iris. The role of a vascular factor...
Serum VEGF levels in infants at risk for developing retinopathy of prematurity
Background: Because excessive growth of abnormal retinal vessels in the developing eye of the premature infant underlies retinopathy of prematurity (ROP), it may be hypothesized that a change in vascular endothelial grow...
Effect of Silicone Hydrogel Contact Lenses on Stability of Cellular and Intracellular Membranes in Corneal Epithelium
Introduction. Contact lenses are increasingly used worldwide for correcting refraction disorders. However, contact lenses can destroy a biochemical composition of the tear. Purpose. To determine the effect of silicone h...
SD OCT retinal thickness in the macula area in premature children who received laser photocoagulation of avascular retina for severe ROP
Background: Immature ocular optics at birth and severe retinopathy of prematurity (ROP) may affect normal development of the retina and lead to late impairment of visual functions. Purpose: To compare spectral-domain op...
