AIM:To compare the results of non-mydriatic ultra-wide field imaging system,mydriatic slit-lamp lens(Volk+90 D) and mydriatic Goldmann three-mirror contact lens examinations in screening fundus lesions among patients after cataract surgery.METHODS:Non-mydriatic images were obtained with an Optomap panoramic 200Tx(Optomap 200Tx) 3d after surgery and graded by a blinded ophthalmologist.A mydriatic slit-lamp lens examination was performed by another blinded retinal specialist on the same day.A third blinded retinal specialist examined patients two weeks after surgery using a Goldmann three-mirror contact lens.RESULTS:In total,160 patients(184 eyes) were examined,and 66,69,and 75 cases of retinal lesion(s)were identified using the Optomap 200 Tx,slit-lamp lens,and Goldmann three-mirror contact lens,respectively.In13 cases,fundus changes were sight-threatening.The results obtained by Optomap 200 Tx examination and by mydriatic slit-lamp lens examination have good consistency(P =0.375,Kappa =0.942).The mydriatic Goldmann three-mirror lens examination revealed more fundus lesions but are consistent with Optomap 200Tx(P=0.004,Kappa =0.897) and mydriatic slit-lamp lens examination(P=0.031,Kappa=0.932).CONCLUSION:Early post-operative fundus screening in cataract patients is extremely important and necessary to prevent further vision loss.Wide-field imaging is a feasible and convenient tool for fundus examination that can be used as a primary screening method among patients after cataract surgery.
