| Summary: |
Purpose: To
evaluate the results of pars plana vitrectomy and
membrane stripping for idiopathic and secondary
preretinal macular membrane (PMM).
Material and methods: Twenty one consecutive
subjects (21 eyes) ranging in age from 40 to 78 (mean
66,9) with PMM underwent vitrectomy and membrane peeling.
17 cases had membranes that were considered idiopathic,
and 4 cases were associated with other disorders: 3
occurred after successful retinal reattachment surgery,
1 - after laserotherapy in the course of diabetic
retinopathy. Visual acuity (VA), Amsler grid, and
postoperative complications were assessed. The follow-up
was 1 to 22 months, mean 5,7.
Results: Visual acuity improved postoperatively
in 15 eyes (71,4%), at least two lines on the Snellen
chart in 8 eyes (38,1%), entirely in patients with
idiopathic PMM. It remained unchanged in 3 eyes (14,3%)
and deteriorated in 3 eyes (14,3%). Eyes with
transparent membrane showed greater visual improvement
than opaque ones. The preoperative Amsler test was
positive in 15 patients (71,4%), postoperatively - in 4
cases (19%). 2 idiopathic cases with VA of 0,7 showed
postoperatively VA of 1,0. Complications included
retinal detachment in 2 eyes (1 in idiopathic and 1 in
secondary PMM), and development of nuclear sclerotic
cataract in 2 eyes. At 6 months of follow-up, a residual
membrane formation in 1 cases appeared. Macular
pseudohole was observed in 1 eye with no impact on
visual results.
Conclusions: 1. Vitrectomy with membrane peeling
for preretinal macular membrane provides improvement in
visual acuity and reduces metamorphopsia 2. Thin,
cellophane-like appearance of the membrane gives a
better prognosis of visual function improvement. |
