Abstract

The aim of this study was to report normative values and ranges of interpupillary distance (IPD) in different age groups of a Turkish population. A total of 756 healthy subjects were included in this prospective study. After a complete ophthalmic evaluation, subjects were divided into four age groups to assess differences between age groups in relation to IPD. The age groups were 20-30, 31-50, 51-70, and 71-89 years. Far IPD measurements were performed using an autorefractometer (Topcon RM-8800). The mean age was 48.42±20.55 years, ranging from 19 to 89 years. The mean IPD was calculated as 62.5±4.1 mm (range 49-76). The mean IPD value was observed to be significantly higher among males compared to females (P<0.001). The difference among groups in terms of mean IPD was statistically significant (P<0.001). IPD increased by 4.19 mm in males and 3.11 mm in females from the young adults (20-30 years) to older adults (51-70 years), and then a decrease (2.6 and 0.19 mm for males and females, respectively) occurred between 70 and 89 years of age. The current study offers the population-specific normative data on far IPD in different age groups. Our study showed that sex and age had a significant effect on IPD. Knowledge of normal values in this population subgroup may be useful in studying orbito-cranial growth patterns, syndrome diagnosis, surgical management of cranio-facial deformities and trauma, and manufactures of optical frames and lenses.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 August 2015.
All research outputs
#9,592,173
of 12,488,808 outputs
Outputs from Clinical Ophthalmology
#922
of 1,597 outputs
Outputs of similar age
#148,284
of 235,651 outputs
Outputs of similar age from Clinical Ophthalmology
#51
of 101 outputs
Altmetric has tracked 12,488,808 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,597 research outputs from this source. They receive a mean Attention Score of 3.2. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 235,651 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 101 others from the same source and published within six weeks on either side of this one. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
