The purpose of this investigation was to study and compare the electrophoretic patterns of optic lensproteins of different species of domestic animals at pre- and post-natal ages. Optic lenses were removed from the embryo or adult sheep, cattle, goat, camel and chicken at the slaughter-house then homogenized and subjected to sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE). I...

purpose: to report the clinico-pathologic features of an opacified single-piece hydrophilic acrylic intraocular lens (iol). patient and findings: a 48-year-old male patient was evaluated for glare and markedly decreased vision in his left eye four years after phacoemulsification and implantation of a single-piece hydrophilic acrylic iol (ophthalmed). best-corrected visual acuity was 20/60 and t...

Objective- Assessment of the lens anterior – posterior (AP) diameter as compared with the eye globe by ultrasonography in rabbit.   Design- Descriptive study.   Animals- 120 male and female rabbits, two months to four years old, and weighting between 300 to 1500gr.   Procedures- 2D ultrasonography of the eyes was performed and AP diameter of the eyes and lens were measured using Sonosite Tit...

This study was conducted to determine the use of three-dimensional ultrasonography (3DU) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3DU of the eyes were done using a 5–12 MHz linear trapezoid transducer. 3DU of the eyes were evaluated and the normal optical long axis through a line between the cornea ...

The induction of the lens by the optic vesicle in amphibians is often cited as support for the view that a single inductive event can lead to determination in a multipotent tissue. This conclusion is based on transplantation experiments whose results indicate that many regions of embryonic ectoderm which would normally form epidermis can form a lens if brought into contact with the optic vesicl...

BACKGROUND We encountered a rare patient with lens luxation in which the lens had become stuck on the optic disc. Findings obtained during vitreous surgery suggested that the luxated lens had become stuck on the optic disc via residual vitreous gel. CASE PRESENTATION An 88-year-old Japanese man experienced lens luxation into the inferior vitreous cavity while undergoing treatment for glaucoma...

Nestin is an intermediate filament protein, which is expressed predominantly in the developing central nervous system and skeletal muscles. In situ hybridization revealed that mouse nestin mRNA is in the optic stalk at 9.0 days post coitus (dpc) and in the lens vesicle at 10.0 dpc. From 14.5 dpc onward, nestin transcripts appear in lens fibers and neuroretina. Immunohistochemistry showed that n...

Objective-  To determine the possibility of three-dimensional ultrasonography (3DUS) and measurement of optical nerve sheet by this method. Design- Descriptive study. Animals- 10 mixed normal dogs (5males, 5 females), age 1-1.5 year, and weighting 15±5 kg Procedure- 3D ultrasounds of the eyes were evaluated and the normal optical nerves in 3DUS images were measured using Volouson 730 pro....
