| description | To characterize quantitatively the configuration of the anterior ocular segment with ultrasound biomicroscopy (UBM) in a population-based setting.
Cross-sectional study.
Ten percent of 4632 residents aged > or =40 years of Kumejima, an island off southwest Japan, were randomly selected.
We performed UBM under light and dark conditions in the 4 quadrants of the right eyes. The anatomic landmarks on the anterior ocular segment UBM images were identified by 1 examiner to quantify the peripheral anterior chamber depth (ACD), location of the ciliary body, and iris thickness.
Angle-opening distance at 250 and 500 microm from the scleral spur (AOD250, AOD500), trabecular-iris angle (TIA), trabecular-ciliary process distance (TCPD), thickness of the iris (ID), trabecular-anterior iris surface angle (TAIA), trabecular-posterior iris surface angle (TPIA), trabecular-ciliary angle (TCA), and thickness of iris measured at 1000, 2000, and 3000 microm (IT1000, IT2000 and IT3000).
The AOD500 averaged 0.267+/-0.138 (mean +/- standard deviation) and 0.202+/-0.116 mm under light and dark conditions, respectively; TIA 22.2+/-10.0 and 17.0+/-8.9 degrees; TCPD 0.755+/-0.165 and 0.748+/-0.152 mm; and ID 0.412+/-0.053 and 0.457+/-0.062 mm.

Angle-opening distance at 250 and 500 microm from the scleral spur (AOD250, AOD500), trabecular-iris angle (TIA), trabecular-ciliary process distance (TCPD), thickness of the iris (ID), trabecular-anterior iris surface angle (TAIA), trabecular-posterior iris surface angle (TPIA), trabecular-ciliary angle (TCA), and thickness of iris measured at 1000, 2000, and 3000 microm (IT1000, IT2000 and IT3000).
The AOD500 averaged 0.267+/-0.138 (mean +/- standard deviation) and 0.202+/-0.116 mm under light and dark conditions, respectively; TIA 22.2+/-10.0 and 17.0+/-8.9 degrees; TCPD 0.755+/-0.165 and 0.748+/-0.152 mm; and ID 0.412+/-0.053 and 0.457+/-0.062 mm. The peripheral ACD was deepest temporally, then nasally, then inferiorly, and then superiorly (P<0.05, post hoc test). The position of the ciliary body was deepest nasally, then temporally, then inferiorly, and then superiorly (P<0.05). Iris thickness did not differ significantly among the quadrants. Older subjects had a shallower peripheral ACD, more anteriorly located ciliary body, and thinner iris (analysis of covariance, P<0.015). The peripheral ACD was deeper and the ciliary body was located more deeply in men than women (P<0.05), although no intergender differences in iris thickness were seen (P>0.1). Hyperopia, short axial length, and shallow central ACD were significantly correlated with shallower peripheral ACD, anteriorly located ciliary body, and thinner iris (P<0.05). Elevated intraocular pressure was associated with a shallow peripheral ACD (P< or =0.043).
There are significant associations of the peripheral ACD, location of the ciliary body, and iris thickness with age, gender, refractive error, axial length, and intraocular pressure.]]></description><identifier>ISSN: 0161-6420</identifier><identifier>EISSN: 1549-4713</identifier><identifier>DOI: 10.1016/j.ophtha.2010.01.045</identifier><identifier>PMID: 20493530</identifier><identifier>CODEN: OPHTDG</identifier><language>eng</language><publisher>New York, NY: Elsevier</publisher><subject>Adult ; Age ; Age Factors ; Aged ; Aged, 80 and over ; Anterior Chamber - diagnostic imaging ; Biological and medical sciences ; Ciliary Body - diagnostic imaging ; Cross-Sectional Studies ; Female ; Glaucoma, Angle-Closure - diagnostic imaging ; Humans ; Hyperopia - diagnosis ; Intraocular Pressure ; Iris - diagnostic imaging ; Japan ; Male ; Medical sciences ; Microscopy, Acoustic ; Middle Aged ; Miscellaneous ; Ophthalmology ; Risk Factors ; Rural Population ; Sex Factors</subject><ispartof>Ophthalmology (Rochester, Minn.), 2010-09, Vol.117 (9), p.1720-1728</ispartof><rights>2015 INIST-CNRS</rights><rights>Copyright © 2010 American Academy of Ophthalmology.
