Effects of n-acetylcysteine amide in preventing/treating cataracts
… amide (NACA), in preventing/reversing cataracts. To investigate NACA's ability to provide therapeutic benefits for cataracts, three different experimental models were utilized. The first was an ex-vivo cataract model, where culturing the rat lenses in dexamethasone resulted in posterior …

The Effectiveness of Prophylactic Eye Drops on the Reversal of UV-Light Induced Cataracts
<p>Cataracts are a cloudiness of the lens within the eye which obstructs vision. They are found in many species including rats, dogs, and humans. Vision is hindered where this "cloudiness", made of water build up and broken crystalline, proteins take form. Oculvet is an eye medication, used by …

Development of Topical Ophthalmic In Situ Gel-Forming Estradiol Delivery System Intended for the Prevention of Age-Related Cataracts
The increased risk of cataracts in aging women versus men, the reduced risk in women on hormone replacement therapy, and studies in animal models suggest that estrogen may protect lens transparency. To use estrogen for cataract prevention, we hypothesized that an ophthalmic estradiol in situ …

The Identification and Characterization of Estrogen Receptors in the Mouse and Human Lens and Their Role in Cataract Development
The increased risk of age-related cataracts in postmenopausal women and studies in animal models suggest that estrogen may have a protective role in the lens. However, very little is known regarding the role of estrogen and its receptors in the lens. To begin unraveling the estrogen signaling …
