RESULTS: CLEK Study subjects had a mean age at baseline of 39.3+/-10.9 years. At study entry, 65% of the patients wore rigid contact lenses, and 14% reported a family history of the disease. Subjects exhibited a 7-year decrease in high- (2.03 letters) and low- (4.06 letters) contrast, best-corrected visual acuity, with 19% demonstrating decreases of 10 or more letters in high-contrast, best-corrected acuity and 31% of subjects demonstrating decreases of 10 or more letters in low-contrast, best-corrected acuity in at least one eye. Subjects exhibited an average 8-year increase in corneal curvature of 1.60D in the flat corneal meridian, with 24% demonstrating increases of 3.00D or more. The 8-year incidence of corneal scarring was 20%, with younger age, corneal staining, steeper baseline corneal curvature, contact lens wear, and poorer low-contrast visual acuity predictive of corneal scarring. Data from the National Eye Institute Visual Function Questionnaire suggest that the effect of keratoconus on vision-specific quality of life is disproportionate to its low prevalence and clinical severity.
This study is from Clek or the collaborative longitudinal evaluation of keratoconus. It came from college of optometry in Ohio.
RESULTS: There were no statistically significant differences among the 3 groups (M, HA, and HI) in race, history of atopic disease, family history of keratoconus, or rigid contact lens wear in the right and left eyes. At baseline, there were no significant differences among the 3 groups in high-contrast best-corrected visual acuity, low-contrast best-corrected visual acuity, or steep keratometric reading. Progression of keratoconus, as assessed by changes in these 3 continuous variables, was equal for the 3 groups. M had more corneal scarring than did HA or HI; however, there was no progression of scarring for any of the groups.
CONCLUSION: Keratoconus progressed in both men and women, aged 48-59 years; however, there were no differences among the groups in progression.
So what we learn her is that if you live in Los Angeles and suffer from keratoconus, there is still a chance of scarring even if you are in your fourties. You need to see Los Angeles cornea expert . Dr Khanna has offices in Beverly hills and west lake village and helps residents of Los Angeles with management of keratoconus.
<ins datetime="2010-12-22T14:45:58+00:Mean age of our patients was 29.5 ± 9.40 years on enrolment, 62.9% males, and the ethnic distribution was 60.3% Chinese, 13.8% Malays, and 9.5% Indians. Clinically-evident keratoconus was present in both eyes of 65 patients (56.0%) and unilateral keratoconus in 5 patients (4.3%). Five patients (4.3%) had a family history of keratoconus. The majority of patients were managed with contact lenses (60.8%) or glasses (24.5%). Eye-rubbing was common (68%) as were atopic conditions such as asthma (26.3%) and eczema (18.4%). Conical protrusion was the commonest sign (75.3%). The mean cylinder was higher in keratoconus eyes compared to keratoconus suspect eyes (-4.01 vs -1.27, p < 0.001) while best corrected VA was significantly poorer (0.19 vs 0.05, p < 0.001). Unaided VA was significantly worse with increasing age (p = 0.016)Baby interesting study from Singapore body chill and Dan has shown that candidate Glenys incidents and the EVA indication population is similar to dad falling in the distant countries like United States Navy studied the allegations of chemical message came to the hospital and found the average age was 30 years and did the range from 20 to 40 years in Singapore this phone does all the population 60% with Chinese & order for Indian origin photo at 5% off then had relatives quit being diagnosed with Canada calling us and butter under treatment most of the patients were meals and or lease sign in the station is depicted in photography laws go any further on vision of function questionnaire because found that activities of the living for affected more than what could have been simply the case for the kind of fish and they had so you give me a mix of common conclusion that keratoconus going to spend presence in early in the eastern hemisphere like a vested hemisphere me of the more commonly affected and it’s a disease that you fix both eyes read it just have I may have a small chance of suffering from the same disease keratoconus
