Abstract:
The intraocular lens is uniquely designed to aid focused vision, and diseases of the lens such as cataracts are a common cause of blindness in dogs. The causes of cataracts are discussed including the main aetiologies such as hereditary cataract, senile and diabetic cataracts. The article focuses on dogs, as cataracts are less common in cats, although traumatic cataracts and rarely, inherited, congenital and developmental cataracts do occur in felines. The article discusses ways to examine and classify a cataract; the best way to diagnose an early cataract is examination with a veterinary opht

Abstract:
Cataracts are a cause of blindness which accounts for approximately half of all blindness in the world, especially in developing countries. The mechanism of cataract formation is highly multifactorial. Loss of transparency in the nucleus and cortex of the lens of the eye can occur as a result of oxidation of membrane lipids, structural or enzymatic proteins by peroxides or free radicals induced by UV light. Other factors that can cause cataract formation are degenerative processes and diabetes mellitus). Cataract therapy is a surgical procedure by removing the cloudy lens, because no medical t

Full clinical examination was performed on individuals from families with inherited cataracts. DNA was extracted from peripheral blood samples. Linkage analysis was performed in three large families.

Cataract patients, especially those with dense cataracts, present a challenge in terms of evaluating their potential visual function because the fundus cannot be clearly visualized and thus many standard clinical techniques fail to provide sufficient, accurate information. Yet, cataracts are the most prevalent cause of visual loss. Moreover, while the incidence of cataracts increases as a function of age, so does the incidence of certain macular and optic nerve/pathway diseases (e.g., age-related macular degeneration (ARMD) and ischemic optic neuropathy).

Abstract:
It is well established that visual acuity underestimates visual impairment due to mild cataract. The principal effect of a cataract is presumed to be an increase in intraocular light scatter which acts as a veiling luminance to reduce retinal image contrast. Glare and contrast sensitivity tests are more sensitive to the effects of intraocular light scatter than tests of visual resolution (acuity), and have been widely promoted for the evaluation of cataracts.

Abstract:
Adverse effects of dense congenital unilateral cataracts on the developing visual system of infants may result from the direct effects of visual deprivation and, in addition, as a result of competition with the normal eye in establishing cortical structure and function during a critical period in visual development. One approach to evaluating these two amblyogenic factors has been to compare the effects of unilateral and bilateral cataracts on visual development. The rationale is that a developing visual system with dense bilateral cataracts suffers only the effects of early visual deprivation

Abstract:
Introduction The induction of cataracts by reducing temperature has proven to be an attractive experimental paradigm for scientists involved in in vitro cataract research because of the speed and simplicity of the method and because cold cataracts are usually reversible (Bon, 1959; Zigman and Lerman, 1964; Lerman and Zigman, 1967). In general, cold cataracts can be induced in mammalian lenses by cooling to temperatures below 10°C but above freezing (Lerman and Zigman, 1967; Siezen et al., 1985; Uga et al., 1986). Age and species differences in the development of cold cataract have led to effor
