Effects of latanoprost and betaxolol on cardiovascular and respiratory status of newly diagnosed glaucoma patients.

Aims: To investigate the cardiovascular and respiratory effects of topical latanoprost 0.005% and topical betaxolol 0.25% monotherapy in newly diagnosed glaucoma patients.

Trypan blue staining of the anterior capsule under an air bubble with a modified cannula.

To attain good visibility of the anterior capsule in the advanced or white cataract, trypan blue 0.1% is used to stain the anterior capsule. The dye is usually injected under an air bubble.

Lens superoxide dismutase and catalase activities in diabetic cataract.

Objective: Biochemical evidence suggests that the oxidative damage of the lens proteins is involved in the genesis of senile cataract and the development of diabetes-related pathologic changes such as the formation of cataracts. In particular, lens proteins are subject to extensive oxidative modification. Oxidative damage either decreases the antioxidant capacity or decreased antioxidant capacity results in oxidative damage.
