| Summary: |
Purpose: To
determine the visual outcome and anatomic closure rate
of macular hole surgery using pars plana vitrectomy with
internal limiting membrane (ILM) peeling.
Material and methods: Fifty three eyes of 52
consecutive patients with a full-thickness idiopathic
macular holes (stage 3 or 4). All eyes underwent a pars
plana vitrectomy including separation of the posterior
hyaloid, ILM peeling with trypan blue (TB) or
indocyanine green (ICG) and gas endo-tamponade with
instructions to the patient, to be face down for 4-5
days. Postoperative anatomic results, visual acuity (VA),
and complications were recorded. The follow-up was 3 to
22 months.
Results: VA improved postoperatively in 45 eyes
(84.9%), at least two lines on the Snellen chart in 24
eyes (45.3%). It remained unchanged in 6 eyes (11.3%)
and deteriorated in 2 eyes (3.8%). The mean preoperative
VA was 0.1±0.04 and does not differ significantly
between stage 3 and 4. The improvement of postoperative
VA was statistically significantly better in stage 3, in
comparison to stage 4. The anatomical success rate (flat/closed)
was 88.7% (47 eyes). There were no differences in VA
improvement between TB- or ICG-stained eyes.
Conclusions: 1. Vitrectomy with ILM removal in
macular holes provides with meaning improvement in
visual acuity. 2. Patients with macular hole in stage 3
have a better prognosis for visual rehabilitation. 3. A
kind of dye and preoperative VA do not influence
postoperative visual function improvement. |
