Cataract, mascular degeneration and glaucoma can be treated and prevented by caloric restriction.



Cataract

Cataract incidence and analysis of lens crystallins in the water-, urea- and SDS-soluble fractions of Emory mice fed a diet restricted by 40% in calories.Curr Eye Res. 1993 Dec;12(12):1081-91.

Restriction of dietary calorie intake is associated with life extension and with the delay of age-related disorders. Preliminary studies demonstrated that by feeding the Emory mouse a diet restricted by 21% in calories cataract and insolubilization of protein could also be delayed. To observe the effects of calorie restriction over prolonged portions of adulthood, Emory mice were fed the control diet (C) or a diet restricted by 40% in calories (R). Feeding the R diet was associated with delayed formation or progress of cataract over virtually the entire second half of life. At 11 months of age, bilateral grade 5 cataracts were present in 17% and 2% of C and R lenses, respectively. At 22 months of age, bilateral grade 5 cataracts were present in 90% and 18% of C and R lenses, respectively. The distribution of alpha-, beta-, and gamma- crystallins in the water-soluble, urea-soluble, and SDS-soluble fractions indicates more similarities than differences between C and R lenses with a specific grade of cataract or of a given age. However, there were significant and abrupt (after grade 4 cataract) losses of particular gamma-crystallins; gamma-crystallins which were not prominent at earlier stages became the major gamma-crystallin moieties. Losses of alpha-crystallins were also noted upon cataract formation or aging in most of the fractions. Aggregates including gamma- and alpha-crystallins also accumulate faster in the C group.

Dietary caloric restriction may delay the development of cataract by attenuating the oxidative stress in the lenses of Brown Norway rats.Exp Eye Res. 2004 Jan;78(1):151-8. Wang K, Li D, Sun F.

Dietary caloric restriction (CR) is the only experimental intervention that can reliably retard the development of cataract in a normal animal model. Here we have studied the possible mechanisms by which CR retards the age-related degeneration of the lens of Brown Norway rats. We have found that CR slowed protein insolubilization and blunted declines of the total
soluble thiols, protein thiols, reduced glutathione and ascorbic acid levels in the lenses of old BN rats. From the lens protein point of view, the development of cataract in rat lenses has 3 stages: (1) the precipitation of gamma-crystallin, (2) the insolubilization of beta-crystallin, and (3) the final precipitation of alpha-crystallin which was saturated with other denatured lens proteins. A similar sequence is also observed when the lens proteins are subjected to oxidative stress in vitro. These data are the first to suggest that CR may retard the age-related degeneration of the lens by attenuating the oxidative stress in the lens. Since oxidative stress is likely a main cause of human cataract, CR intervention may be relevant to humans as well.

The neural retina of mammals consists of light sensitive photoreceptors and connecting neural cells that receive and send visual signal to the brain. Dietary caloric restriction (CR) is the only experimental intervention that can reliably retard the age-related degeneration of the retina in a normal mammalian model. Here, we studied the effect of CR on various biochemical parameters in the retina of male Brown Norway rats at different ages. We found that CR slowed the age-dependent protein insolubilization, blunted the declines in the total soluble thiols, and reduced glutathione and ascorbic acid levels in neural retina. We also observed that CR retarded the age-related decline in the levels of taurine, a vital amino acid in neural retina. These data are the first to implicate that CR may retard the age-related degeneration of retina by attenuating the oxidative stress and/or by sustaining the pool of protective factors in the neural retina.

Glaucoma

Effects of age and long-term caloric restriction on the aqueous collecting channel in the mouse eye.

PURPOSE: The mouse aqueous collecting channel, part of the mouse aqueous outflow pathway, was measured using a computer-assisted image analysis system. We used ad libitum-fed and calorie-restricted mice to investigate the effects of age and long-term caloric restriction on the lumen size of the channel.
RESULTS: The ad libitum-fed mice showed a significant age-related reduction in the lumen area. In the ad libitum-fed group, the lumen area of the channel decreased  by 30% at 30-35 months of age (p < 0.01), and the anteroposterior width declined by 21% (p < 0.001) as compared with mice 3-5 months of age. The calorie-restricted mice did not display any reduction with age in the lumen area or the anteroposterior width of the channel. When compared with the age-matched calorie-restricted mice, the lumen area of the  channel of the ad libitum-fed mice measured less by 34%, and anteroposterior width less by 21% at 30-35 months of age (p < 0.01).
CONCLUSIONS: These results indicate that an age-related morphological alteration in the mouse aqueous collecting channel occurred and that it is delayed by long-term caloric restriction. This suggests a possible role of life-long caloric restriction in reducing glaucomatous damages and perhaps delaying glaucoma development.
