The aim of this study is to show, whether long-term results of relaxing retinotomy in complicated retinal detachment ( RD) cases, are satisfactory, compared to early ones.
In three different Eye Clinks in the period between 2006-2007, 56 patients were retrospectively evaluated for the results of the surgical procedure.In 35 patients proliferative vitreoretinopathy (PVR) was the cause for RD, in 12 trauma and in 9 patients inflammatory retinopathy. Out of 56 patients, 43 underwent through one or two prior ppv. The PVR grade ranged between C4-C12. 20 and 23 gauge ppv with relaxing retinotomy was performed in 90-180 degrees in 34 cases, 13 cases limited to 2-3 clock-hours and in 9 in more then 180 degrees retinotomy.Endoleser and retinal cryocoagulation, for the anterior retinotomy edges was performed. As endotamponade agent silicon oil was used in 45 eyes and gas tamponade (C3F8) in 19 eyes.
Single procedure success was present in 48/56 patients (85.7%). Surgical failure was seen in 3/8 patients, while slippage of the retinotomy edge in 2 patients. PVR redetachment in 2 cases, and hypotony in 1 case, in the first year. Between the first and the third year of follow-up additional PVR redetachments were registrated in 5 patients. After first year of follow-up, visual acuity (VA) improved in 69.8%, remained unchanged in 23%, and decreased in 7.1%, compared to the 3rd year of follow-up and VA improvement in 43%, unchanged in 37%, and decreased in 20%.
Relaxing retinotomy allows reattachment of retinas that are otherwise irreparable. Long-term results are not satisfactory enough, compared to early ones, and one-year follow-up results.
