The lack of established diagnostic criteria or large-scale epidemiological studies, low awareness of the syndrome, and the unstandardized diagnosis criteria and definition for<unk>  means that the exact prevalence of the syndrome is currently unknown. One study on 3,224 adolescents in Japan demonstrated the occurrence of macropsia and micropsia to be 6.5% in boys and 7.3% in girls, suggesting that the symptoms of<unk>  may not be particularly rare. This also seems to suggest a difference in the male-to-female ratio of people with<unk> . However, according to other studies, it appears that the male/female ratio is dependent on the age range being observed. Studies showed that younger males (age range of 5 to 14 years) were 2.69 times more likely to experience<unk>  than girls of the same age, while there were no significant differences between students of 13 to 15 years of age. Conversely, female students (16- to 18-year-olds) showed a significantly greater prevalence.<unk>  is more frequently seen in children and young adults. The average age of the start of<unk>  is six years old, but it is very normal for some people to experience the syndrome from childhood up to their late 20s. Because many parents who have<unk>  report their children having it as well, the condition is thought possibly to be hereditary. Some parents report not realizing they have experienced<unk>  symptoms until after their children has been diagnosed, further indicating that many cases of<unk>  likely go unrecognized and underreported. Research is still being expanded upon and developed on this syndrome in a multitude of different regions and specialties. Future studies are encouraged to include global collaborative efforts that may help improve understanding of<unk>  and its epidemiology.
