Abstract

Purpose : To observe the changes in ocular biometric measurements after vitrectomy with silicone oil tamponade for rhegmatogenous retinal detachment repair.

Methods : Measurements of axial length, anterior chamber depth, lens thickness using the new Zeiss IOLMaster 700 and derivative lens position, relative lens position and lens-retina distance were compared between preoperative and postoperative in phakic, macula-off eyes with rhegmatogenous retinal detachment. Linear regression was performed to show the correlations between patient characteristics and changes in measurements.

Results : Sixty-three patients with an age range from 28 to 75 years were included. Preoperative axial length, anterior chamber depth, lens thickness, lens position, relative lens position and lens-retina distance were 24.94 ± 1.82 mm, 3.45 ± 0.42 mm, 4.34 ± 0.16 mm, 5.55 ± 0.41 mm, 0.22 ± 0.01 and 19.52 ± 1.82 mm. After a mean 4.85-month duration of silicone oil tamponade, postoperative axial length, anterior chamber depth, lens thickness, lens position, relative lens position and lens-retina distance were 25.42 ± 2.20 mm, 3.30 ± 0.41 mm, 4.43 ± 0.21 mm, 5.46 ± 0.40 mm, 0.22 ± 0.02 and 20.17 ± 2.36 mm. The differences in all measurements between preoperative and postoperative are significant (all P < 0.05). Preoperative axial length and lens-retina distance are positively while relative lens position is negatively correlated with change in lens-retina distance. Change in axial length but not in lens thickness or lens position is correlated with change in lens-retina distance.

Conclusions : There are prolongation of axial length and anterior shifting of lens in phakic, macula-off eyes with rhegmatogenous retinal detachment after vitrectomy with silicone oil tamponade.
