Objective
To observe the effect of preservation of an terior lens capsule on the incidence of complications associated with silicone oil.
Methods
Eighty-two patients(82 eyes)accepted trans pars plana vitrectomy combined with lensectomy,30 eyes with preservation of an terior lens capsule (PAC) and 52 eyes with no preservation of anterior capsule(N PAC)were observed.The incidence of complications was analysed to investigate whe ther PAC could reduce the complications associated with the usage of tamponade of silicone oil.
Results
The incidence was 50.0% in NP AC group,and 23.3% in PAC group(0.010lt; Plt; 0.025).There were secondary glaucoma(21.1%),band keratopathy(13.5%)and corneal decompensation(9.6%)in NPAC group,while there was none of them in PAC group.
Conclusion
Preservation of anterior lens capsule is an effective measure to reduce the complicaltons associated with the tamponade of silicone oil.

Objective
To evaluate the efficacy and its affecting factors of silicone oil as an introocular tamponade for copmlicated retinal detachments in children(le;14 years).
Methods
We analysed retrospectively 34 cases(36 eyes) of complicated retinal detachments in children, who were performed with pars plana vitrectomy combined with silicone oil tamponade from June 1993 to November 1997.
Results
After 3-21 months of follow-up, the detached retinas in 19 eyes(52.7%) were reattached, in 10 eyes(27.8%) partially reattached and in 6 eyes (16.7%) redetached, 1 eye(2.8) had a media opacity that precluded evaluation of the retina. Postoperative visual acuity was less than 0.05 in 12 eyes(33.3%), and 0.05-0.2 in 20 eyes(55.6%), 2 cases(4 eyes) could not tell their visions(11.1%).
Conclusion
Silicone oil tamponade is an effctive therapy for complicated retinal detachments in children. The major cause of surgical fai;ure was development of recurrent proliferative vetrioretinopathy.
