TECHNIQUES
FOR THE MANAGEMENT OF ANTERIOR & SUBRETINAL PVR
Steve Charles, MD
United States
Purpose: To describe
the advantages and disadvantages of various methods used to manage anterior
PVR based on a single surgeon, in a prospective, consecutive series of
1418 operated cases.
Methods: Detailed description of methods used by the author and comparison
to other methods that have been described. Techniques to be described
include: 1. Scissors segmentation of narrow antero-posterior component
using fine curved scissors, 2. InnoVit cutter with flow limiting via high
cutting rates for resection of broad antero-posterior component, 3. Circumferential
retinectomy, 4. Scissors segmentation of circumferential component, 5.
diamond coated forceps for inside-out peeling of epiretinal membranes,
6. punch-thru retinotomy to remove subretinal dendrites, 7. vitrectomy
and retinectomy under air, 8. permanent silicone oil, use of the Chang
end-aspirating laser probe for fluid-air exchange and all internal drainage
of subretinal fluid, 9. small posterior drainage Retinotomies
Results: The techniques listed under Methods were found to be more effective
than pics, relaxing retinotomy, and outside-in peeling. Permanent silicone
oil was found to have no cases of corneal damage and the glaucoma incidence
was 11% in a series of 450 cases. Pseudophakic eyes were found to be ideal
for utilization of permanent silicone oil.
Conclusions: Anterior PVR surgical management requires a combination of
specific techniques each directed at the three components of anterior
PVR: antero-posterior, circumferential, and confluence of the anterior
vitreous cortex and posterior vitreous cortex. It was also concluded that
it is not necessary to remove silicone oil in
