Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Partial posterior hyaloidectomy (a modified procedure of vitrectomy)
The core vitrectomy entails more extensive removal of vitreous gel, in contrast to the conventional core vitrectomy. IPVD was conducted by engaging the attached posterior cortical vitreous with a 23-gauge needle with angulated tip in the area adjacent to the optic disc followed by gently moving the tip to approximately 3 disc diameters away from the margin of the optic disc. After then, slightly elevating the tip in a posteroanterior direction with slowly proceeding it to the extent that we planned. With IPVD, the surgeon was able to visualize a floating Weiss ring in all of the cases. Active suction to initiate IPVD was not used in any of the cases. In the temporal direction, the extension of a PVD was restricted to approximately 2 disc diameters distance beyond the margin of temporal major vascular arcade
