PURPOSE To identify the genetic cause responsible for the autosomal dominant hereditary cataract in a Chinese family. METHODS A whole family of a proband who has a dominant congenital pulverulent nuclear cataract was recruited into Zhongnan Hospital. The lenses of patients were observed by a slit-lamp microscope, and the lenses of the proband's mother were analyzed by scanning electron micros...

BACKGROUND Cataract surgery remains a commonly performed elective surgical procedure in the aging and the elderly. The purpose of this study was to utilize time series methodology to determine the temporal and seasonal variations and the strength of the seasonality in age-related (senile) cataract hospitalizations and phacoemulsification surgeries. METHODS A retrospective, cross-sectional tim...

purpose : to investigate tear film status after phacoemulsification surgery with temporal and supratemporal clear corneal incision in a cohort of patients with senile cataract methods : we enrolled sixty eight eyes of 68 patients with senile cataract requiring phacoemulsification in a prospective, cohort study. all patients undergone basic tear secretion test (btst), tear meniscus height (tmh),...

Sir, We congratulate Mathur and Pai for their interesting article entitled, “Comparison of serum sodium and potassium levels in patients with senile cataract and age‐matched individuals without cataract,”[1] in which they noted significantly higher mean serum sodium levels in individuals above 50 years of age with cataract than in age‐matched individuals without cataract; however, mean serum po...

BACKGROUND The antioxidant melatonin effectively scavenges highly toxic hydroxyl radicals. Decreases in circulating melatonin levels have been reported in patients with diseases that become more serious with advancing age. The purpose of the present study was to explore the relationship between circulatory melatonin level and the extent of senile cataracts. To this end, we assessed the urinary ...

An attempt has been made to explore the possible role of Taurine in cataractogenesis. Normal lenses were obtained from eye bank donors and cataractous lenses from patients who had undergone surgery for cataract extraction. Lenses were weighed and homogenised. Extraction, isolation and estimation of protein and taurine were carried out. It has been found that the lens wet weight increased progre...

The aim of the present study was to detect senile nuclear cataract lens density and provide a quantitative measurement of lens density for the long-term clinical observation of cataracts. An Anterior Segment Analysis System was used to detect the lens density of 422 simple senile cataract eyes and normal contralateral eyes. The density values were taken at the optical axis at various depths mea...

Six glycosidases were determined in: (1) lenses of alloxan-diabetic rats; (2) rabbit lenses incubated in high-glucose media in vitro; and (3) human senile cataracts, diabetic senile cataracts, and autopsy lenses. In diabetic rat lenses, the activities of /3-glucosaminidase, fi-galactosidase, and P-fucosidase increased with cataract progression as compared to control lenses. Glycosidase activiti...

Purpose: This study set out to examine the impact of surgical treatment senile cataract on visual acuity and quality life in patients operated a public teaching hospital. Methods: Prospective including aged over 60 years with clinical indications for surgery treated at medical residency service. The National Eye Institute Visual Function Questionnaire 25 was applied. Corrected distance measured...

were especially prone to get cataract, a systematic description of the condition did not appear till 1834 when Berndt published his description (Kirby, 1933). Two types of cataract have been defined clearly in our times by Duke-Elder (loc. cit.) but it must be pointed out that references to these types are not wanting in the writings of earlier authors, especially in those of Beard in the middl...
