Type VII Collagen in the Human Accommodation System: Expression in Ciliary Body, Zonules, and Lens Capsule.
Purpose To investigate intraocular expression of COL7A1 and its protein product type VII collagen, particularly at the accommodation system. Methods Eyes from 26 human adult donors were used. COL7A1 expression was analyzed in ex vivo ciliary epithelium by microarray. Type VII collagen distribution was examined by Western blot analysis, immunohistochemistry. and immuno-electron microscopy. R...
متن کاملCrystalline lens stretching device for simulation of accommodation.
According to Helmholtz it is nowadays accepted that one of the major reasons for the development of presbyopia is the increasing sclerosis of the crystalline lens. Therefore the investigation of the process of accommodation of the lens is an important field of research. Our aim was to simulate the process of accommodation in-vitro and to measure the changes of geometry of the crystalline lens m...
متن کاملAdult Ocular Toxocariasis Mimicking Ciliary Body Malignancy
Purpose. To discuss an unusual presentation of ocular toxocariasis. Methods. Case report. Results. A 40-year-old woman presented with decreased vision in the left eye with a long history of recurrent red eye from uveitis. Eosinophilia and positive ELISA titers for Toxocara canis favored the diagnosis of ocular toxocariasis. Over 3 months, an anterior scleral mass had a rapid growth raising the ...
متن کاملHistoanatomical study of the lens and ciliary body in ostrich eye
In the present study, the lenses and ciliary bodies of 20 ostrich eyes were studied macroscopically and microscopically. The histological slides were studied after staining by hematoxylin and eosin, Verhoeff, Van Gieson, and periodic acid-Schiff (PAS). Posterior surface of lens was more convex than its anterior surface. The average lens diameter and thickness were respectively measured as 1.43 ...
متن کاملChanges in monkey crystalline lens spherical aberration during simulated accommodation in a lens stretcher.
PURPOSE The purpose of this study was to quantify accommodation-induced changes in the spherical aberration of cynomolgus monkey lenses. METHODS Twenty-four lenses from 20 cynomolgus monkeys (Macaca fascicularis; 4.4-16.0 years of age; postmortem time 13.5 ± 13.0 hours) were mounted in a lens stretcher. Lens spherical aberration was measured in the unstretched (accommodated) and stretched (re...
