Purpose:To investigate the anterior segment in nanophthalmic eyes and their association with intraocular pressure after cataract surgery.Methods:Thirty-two nanophthalmic eyes(axial length[AL]<18.5 mm)in 18 patients and 35 normal eyes(21≤AL≤24.5 mm)in 35 controls who had undergone uneventful cataract surgery were included.Swept-source optical coherence tomography was used to compare the anterior segment structures between the two groups.The associations between the anterior segment characteristics of nanophthalmic eyes and postoperative intraocular pressure(IOP)were also investigated.Results:The IOP-lowering effect of cataract surgery was remarkably insufficient in nanophthalmic eyes.Peripheral anterior synechiae(PAS)were observed in 56%(18/32)of nanophthalmic eyes,and a characteristic boomerangshaped iris was observed in 28%(9/32).The anterior surface of the iris seemed“smoother”in nanophthalmic eyes than in normal eyes.Schlemm’s canal(SC)diameter,SC area,trabecular meshwork(TM)thickness,TM width,and TM area were generally smaller in the nanophthalmic eyes.Younger age,higher preoperative IOP,broader PAS,and smaller SC area were main contributors to higher postoperative IOP.AL and SC diameter may also be of great importance in IOP prediction in patients without glaucoma surgery and PAS.Conclusions:The morphological features of the anterior segment in nanophthalmic eyes are significantly different from those of normal eyes.Influencing factors such as age,AL,preoperative IOP,extent of PAS,SC and TM size could all be prognostic for IOP after cataract surgery in nanophthalmic eyes. 展开更多
