Background/Aim. Age-related cataract is a common disease among senior
population. Vitamin C is the most effective reducing hydrosoluble antioxidant
causing reduction in the levels of free radicals in crystaline lens. The aim
of this study was to evaluate the age-related change of vitamin C (L-ascorbic
acid) level in the aqueous humor of patients with senile cataract. Methods.
This prospective study included 74 patients, divided into 3 age groups, with
age-related cataract, underwent routine phaco cataract surgery with
intraocular lens implantation. Aqueous humor was aspirated from 74 eyes at
the beginning of phacoemulsification. The levels of vitamin C (L-ascorbic
acid) in aqueous humor were determined with high-performance liquid
chromatography (HPLC). Results. The average age of patients included in the
study was 65 ± 9.85 years (54-87 years). The level of vitamin C in aqueous
humor was 152.78 ± 7.0125 μg/mL in the group A (50-59 years), 134.15 ± 5.1569
μg/mL in the group B (60-69 years) and 106.51 ± 5.44 μg/mL in the group C
(over 70 years). Conclusion. The amount of vitamin C in aqueous humor of
patients with age-related cataract is decreasing with age. There was a
statistically significant change (p < 0.001) of vitamin C aqueous
concentration in the patients of different age. This decrease could play a
role in susceptibility to cataract formation in older population.
