PURPOSE To assess the heritability of anterior chamber depth (ACD) and relative anterior chamber depth (ACD/axial length, rACD) in Chinese in a classic twin study. METHODS Twins aged 7 to 15 years living in two local districts were recruited from the Guangzhou Twin Registry. Anterior chamber depth and axial length were measured by partial coherence laser interferometry. Zygosity in all same-sex twin pairs was confirmed by genotyping with 16 polymorphic markers. The phenotypes of the right… 
Shared genetic determinant of axial length, anterior chamber depth, and angle opening distance: the Guangzhou Twin Eye Study.
TLDR
Analyses of Chinese children twin data suggest that shared genes are responsible for the significant phenotypic correlations found for AL ACD, and AOD.
Heritability of the iridotrabecular angle width measured by optical coherence tomography in Chinese children: the Guangzhou twin eye study.
TLDR
The variance in drainage angle width in Chinese children appears to be largely attributable to genetic effects, with a heritability of approximately 70%.
Distribution and heritability of iris thickness and pupil size in Chinese: the Guangzhou Twin Eye Study.
TLDR
Iris thickness is thinner in girls but is not associated with age in children, and the variation is largely attributable to additive genetic effects.
Contribution of genetic and environmental effects on lens thickness: the Guangzhou Twin Eye study.
TLDR
It is confirmed that the LT in young healthy subjects may be mainly affected by additive genetic factors, and high heritability remains even when the data are corrected for the influence of AL with the use of rLT.
Distribution and heritability of peripheral eye length in Chinese children and adolescents: the Guangzhou Twin Eye Study.
TLDR
Additive genetic effects had a substantial influence on phenotypic variation in PEL and RPEL, suggesting genetic rather than environmental factors play a major role in determining eye shape.
Shared genetic determinants of axial length and height in children: the Guangzhou twin eye study.
TLDR
Covariance of AL and height is largely attributable to shared genes, which is a key determinant of myopia, and further work is needed to confirm gene sharing between myopia and stature.
Genetic Covariance Between Central Corneal Thickness and Anterior Chamber Volume: A Hungarian Twin Study
TLDR
The findings support the high heritability of ACV and central corneal thickness, and a strong genetic covariance between them, which underscores the importance of identification of the specific genetic factors and the family risk-based screening of disorders related to these variables.
Heritability of Anterior Chamber Indices in Rural Population
TLDR
The high heritability of the anterior chamber angle points to a high correlation between this phenotype and genetic factors and further genetic and molecular investigations are suggested to find the related genes and understand the etiology of glaucoma.
Genotype-ocular biometry correlation analysis of eight primary angle closure glaucoma susceptibility loci in a cohort from Northern China
TLDR
The SNP rs3753841 in COL11A1, rs1258267 in CHAT and rs736893 in GLIS3 are associated with PACG in northern Chinese people, and the association of genetic markers manifests a tendency of ethnic diversity.

TLDR
Genetic factors play a significant role in refractive error (myopia and hypermetropia) as well as in ocular biometrics, particularly axial length.
The importance of genes and environment for ocular refraction and its determiners: a population based study among 20–45 year old twins
TLDR
A high heritability for ocular refraction and its determiners is indicated and the results suggest that environmental impact on refraction is not significant, but the epidemiological association between educational length and myopia, the evidence of increasing myopia prevalence within a few generations, and the theory of gene-environment interaction imply some individuals might be genetically liable to develop myopia if exposed to certain environmental factors.

TLDR
The genetics of primary angle-closure glaucome was studied, indicating that about two thirds of the age and sex independent variation in ACD seems to be genetic.

TLDR
Significant age, sex, and ethnic variations were demonstrated, the lower levels of both parameters being found in elderly persons, women and Eskimos, respectively and Danes showed a lower level of LCD scores than reported in Americans.

TLDR
ACD measurement differences with the 3 studied devices proved to be statistically significant; however, these minor differences may be clinically negligible depending on the use of the measurement.

TLDR
The traditional view that primary angle closure becomes a significant possibility in drainage angles of ⩽ grade 2 (approximately 20°) is valid in east Asians and probably serves to underemphasise the role of PAC in population surveys of glaucoma prevalence in Asian people.

TLDR
Over many years, and by careful dissections of cadaver and enucleated eyes, Priestley Smith concluded that the shallow anterior chamber occurred already before the disease (glaucoma), was an expression of disproportion between the size of the eyeball and the lens, and was an important aetiological consideration for glaucomA.
