The surgical complications of cryotherapy combined with C3F8 intraocular temponade in treatment of superior rhegmatogenous retinal detachment

Objective To investigate the clinical results and surgical complications associated with eryotherapy combined with C3F8 temponade in the treatment in superior rhegmatogenous retinal detachment. Methods Twenty-six consecutive patients with superior rhegmatogenous retinal detachment were included. Cryotherapy and C3F8 temponade were performed in all patients.Face-down position for 1 week was required after the surgery. Result Elevated IOP were noted in 6 eyes,vitreous opacities in 4 eyes within the 1st month post-operatively.Reversible posterior subcapsular opacity was found in 16 eyes.Retinal redetachment were found in 3 eyes due to reopening of retinal tear (1 eye) or new tear (2 eyes) within 1 month postoperatively.Proliferative vitreoretinopathy were developed in 2 eyes.Further vitreotomy were performed in these 5 eyes. Conclusions Cryotherapy combined with C3F8 intraocular temponade is an effective,easy and less invasive surgery in superior retinal detachment.The post-operative complications including increased IOP,vitreous opacity,retinal redetachment and proliferative retinopathy should be considered.
