Prevalence of pterygium and pinguecula: The Blue Mountains Eye Study

Abstract

The study found significant associations between pterygium and increased pigmentation (skin and hair colour), decreased skin sun sensitivity and sun-related skin damage. The age- and sex-specific pterygium prevalence rates in the present study are simi ar to rates found in non-Aboriginals examined in the 1980 Australian Trachoma Programme.

Pterygium in an aged Mongolian population: a population-based study in China

“…15 In the Blue Mountain Eye Study, the prevalence was 7.3% for participants aged 49 years or older. 21 The prevalence of pterygium among 477 residents on a tropical island in Indonesia, however, was high, at 17.0%, 22 and the black population of the Barbados Eye Study was even higher, 23.4% of 2617 participants were aged 40-84 years. 23 The highest prevalence of pterygium, to our knowledge, was in subjects aged 50 years or above in a rural area of southern China, 33.01%.…”

“…The HES found no statistical significance in pterygia between men and women, which is consistent with some reports. 9,21,28,29 From two studies conducted in China, women were at higher risk than men. 10,20 The Blue Mountains Eye study 21 and the Tanjong Pagar survey 15 found that men were at higher risk than women; similar results were found by McCarty et al 9 and Moran and Hollows.…”

Comparison of pre-operative and post-operative astigmatism and visual acuity after pterygium excision followed by sutureless and gluefree conjunctival autograft

“…Pterygium is a worldwide ocular disease which is particularly more common in tropical and sub tropical area [20][21][22][23]. The development of a pterygium can lead to significant astigmatism.…”

Pinguecula and contact lenses

“…The development of pinguecula is associated with aging. [1][2][3][4][5][6] We previously examined the incidence of conjunctivochalasis in a hospital-based population 7 and in contact lens (CL) wearers. 8 We found that the prevalence and severity of conjunctivochalasis were dependent on both the age 7 of the subjects and the duration of wearing CLs.…”
