Retinal Detachment Clinical Trial
Official title:
Partial Posterior Hyaloidectomy in Macular Surgery : A Modified Procedure of Vitrectomy to Prevent Retinal Break Related to Induction of a Posterior Vitreous Detachment
To evaluate the effect of partial posterior hyaloidectomy on preventing iatrogenic retinal breaks related to induction of a posterior vitreous detachment
The induction of a posterior vitreous detachment (IPVD) during vitrectomy have been
suggested as one of the etiologies of iatrogenic retinal break related to vitrectomy.The
iatrogenic retinal breaks related to IPVD usually develop near or anterior to the equatorial
region.
Thus, the investigators hypothesized that this complication could be prevented by
restricting the extent of IPVD, and planned a modified procedure of vitrectomy in which the
extent of IPVD and removal of vitreous cortex was restricted to about slightly beyond the
margin of temporal major vascular arcade.
The investigators have termed this procedure, partial posterior hyaloidectomy. Unlike RRD or
proliferative diabetic retinopathy, lesions are localized within the major vascular arcade
in macular disorders so that macular disorders could be an eligible indication for this
procedure.
