Abstract Details



Purpose:

Using the proportional reflux feature on the CONSTELLATION® vision system “hydrodissection” between normal retinal tissue and fibrous tissue in complex diabetic tractional retinal detachments, to separate them with relative ease, making it a time efficient procedure with minimal instrumentation.

Setting:

Vitreoretinal and uveitis services, Advanced Eye Centre, Department of Opthalmology, Pgimer ,Chandigarh, India

Methods:

This method utilizes the newer microincisional vitrectomy surgery instruments which are smaller gauge and have port closer to the tip, alongwith the proportional reflux mode on CONSTELLATION® vision system which allows fluid to be ejected in gradual and controlled manner with foot pedal control. The port of the vitreous cutter is placed between the fibrovascular tissue and normal retina, using the foot pedal the surgeon uses fluid extrusion in a proportional manner to create a separation plane between the fibrous tissue and normal retina, the separated tissue can then be dissected using the vitreous cutter.

Results:

We present the video of 3 patients , using the “PROPORTIONAL REFLUX HYDRODISSECTION” in complex Diabetic Tractional retinal detachments, demonstrating ease of separation of fibrovascular tissue from normal retina, simultaneously pushing normal retina away preventing any iatrogenic breaks, minimal instrumentation with surgery being completed in such cases solely with the help of vitreous cutter making it time efficient , economical technique and avoiding need of any bimanual procedure.

Conclusions:

Using the proportional reflux feature on the CONSTELLATION® system “hydrodissection” between normal retinal tissue and fibrous tissue can be done with relative ease, making it a time efficient procedure with minimal instrumentation
