摘要

AIM:To investigate the relationship between the ultrasound biomicroscopic(UBM) features of anterior-segment cysts(ASCs) and increased intraocular pressure(IOP) as a risk factor for closed-angle glaucoma(CAG).·METHODS:Totally 24 eyes with recently diagnosed ASCs were divided into two groups.First group with ASC and ocular normotension(n =13),second group with ASC and ocular hypertension(n =11).An ophthalmologic examination,including tonometry,slit-lamp biomicro-scopy(SLBM),gonioscopy,fundoscopy,pentacam,and UBM,was performed.The features of the ASCs were compared with the IOP.·RESULTS:ASCs were accurately diagnosed and delineated in 24 eyes using UBM.IOP was elevated in those ASCs with a secondary aetiology(P =0.027),iridociliary location(P =0.006),deformed shape(P =0.013),increased size(P =0.001) and elongated pupillary aperture(P =0.009).However,the count(P =0.343) of ASCs,anterior chamber depth(ACD;P =0.22) and axial lenght(AL;P =0.31) were not associated with ocular hypertension.Correlations were found between the IOP and ASC size(r =-0.712;P =0.003),anterior chamber angle(ACA;r =-0.985;P 【0.001),angle opening area(AOA;r =0.885;P【0.001),angulation of iris(r =-0.776,P 【0.001),and affected iris quadrant(r =-0.655,P =0.002).·CONCLUSION:Ocular hypertension in some eyes with ASC might be associated with various mechanisms,including secondary aetiology,iridociliary location,deformed shape,increased size and elongated pupill,which can be determined by UBM.
