Objective To evaluate a method of ultrasound biometry in silicone oil-filled eye and its clinical results.Methods This was a series case study.According to the principle of measuring a distance with ultrasound,we compared the measured distance between a space filed with balanced salt solution and silicone oil at same height,to ealculate a conversion factor (0.674) between them.A formula for corrective axial length in silicone oil-filled eye was established.The formula:ab+0.674×bc(a,b and c standing for the apex of the cornea,the posterior pole of the lens or the center of the capsular membrane and the anterior surface of the machlar,respectively).the axial lengths of 150 silicone oil-filled eyes in 150 cases were then measured before and after silicone oil removal with Vivid 7 Dimension ultrasound.According to the axial length,they were divided into two groups,namely group 1(the length<25mm)and group 2(thelength≥25 mm).In 76/150 eyes,before combined silicone oil removal and intraocular lens (IoL)implantation,the SRKT formula was used for intraocular lens calculation;the post-operative actual refraction was compared with the pre-operative predicted refraction and statistics analysis was made.Results The retinal condition of 150 silicone oil-filled eyes in 150 cases after 3 months'fllow-up was stable after surgery.The results of the biometry were as follows.In the first group,the mean corrective axial lengths of 111 silicone oil-filled eyes before silicone oil removal was (22.77±1.00)mm(ranging from 21.10 to 24.90 mm);the mean axial lengths after silicone oil removal was(22.76±0.99)mm(ranging from 21.00 to 24.70 mm).The difference between them was not statistically significant (t=0.518,P>0.05).The vitreous cavity depth before and after silicone oil removal was (26.57±2.14)mm and(17.90±1.38)mm,respectively.The ratio of the latter to the former was 0.673 78.In the second group.the mean corrective axial lengths of 39 sillcone oil-filled eyes before silicone oil removal was(26.52±1.31)mm(ranging from 25.00 to 30.58mm);the mean axial lengths after silicone oil removal was(26.53±1.29)mm(ranging from 25.00 to 30.59 mm).The difference between them was not statistically significant(t=0.109,P>0.05).The vitreous eavity depth before and after silicone oil removal was (32.01±2.90)mm and(21.57±2.04)mm,respectively.The ratio of the latter to the former was 0.673 95.In 76 eyes with IOL,the post-operative actual refraction after at least 3 months follow-up was compared with the pre-operative predicted refraction (-1.50 DS)in both groups.The differences between them were not statistically significant(t_1=0.253,P_1>0.05;t_2=0.209,P_2>0.05)in each group.Conclusion Ultrasound biometry in silicone oil-filled eye is accurate and simple,and has good results in clinical measurement.
