AN UNUSUAL LUXATION OF THE CRYSTALLINE LENS.

Trauma of the Crystalline Lens

Physiology of Crystalline Lens

Ageing and the crystalline lens

Ageing leads to gradual loss of the crystalline lens's three main functions due to changes in the transparency and rigidity of the latter, and following various biochemical and ultra structural alterations. Opacification causes the appearance of senile cataract, which is the main cause of vision loss worldwide. Hardening of the crystalline lens gradually restricts accommodation, leading to pres...

Mapping the mutation causing lens luxation in several terrier breeds.

Primary lens luxation (PLL), a painful and blinding inherited condition, is common in several breeds of terrier. Here we have examined the Veterinary Medical Database of patient encounters and Canine Eye Registration Foundation (CERF) cases records for the last 10 years and found the diagnosis recorded in 85 breeds. We have performed association analysis using a genome-wide microsatellite scree...

The Differentiation of the Crystalline Lens

T H E first sign of lens development in the vertebrate embryo is the appearance of a thickening of the head ectoderm in the area of contact between the ectoderm and the eye vesicle (lens placode). The cytoplasm of the placode cells in the chicken embryo loses its vacuolization, the cells acquire a cylindrical form, the nuclei arrange themselves perpendicularly to the contact surface and move to...
