Lens thickness in early cataract.

Lens thickness in early cataract.

The search for environmental factors associated with cataract has produced conflicting evidence and one possible reason may be that environmental influences are initiating events occurring perhaps for short periods many years before loss of sight from cataract. It is important, therefore, to be able to detect the earliest changes of cataract formation so that epidemiological studies have a bett...

The thickness of the human lens cortex in the different types of senile cataract.

In every type of beginning senile cataract the cortex of the lens measured with the slit lamp appears thinner than the normal lens cortex in the same age group. The decreased rate of fiber formation and of proteosynthesis precedes the first appearance of lens opacities.

Antibodies to lens antigens in cataract and after cataract surgery.

By means of an enzyme-linked immunosorbent assay (ELISA) antibodies to whole lens homogenate were found in 50.0% of 38 patients with senile cataract and in 57.3% of 75 controls. The antibody titres were in the range of 10-160 in both groups. IgG antibodies occurred in 44.7% of patients and in 45.3% of controls, whereas IgM antibodies were found in 21.1% of the patients and in 40.0% of the contr...

Treatment of ophidism-induced bilateral canine cataract by extracapsular lens extraction and intraocular lens implantation

The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...
