contrast, patients with impending holes still had
a PRL located inside the hole area (Fig. 1.5). Stability
of fixation shows no significant correlation
with visual acuity [20, 40].
Because surgical repair of advanced macular
holes has become the treatment of choice, additional
data concerning functional development
over time have been added. Haritoglou and coworkers
described the occurrence of paracentral
scotomata in patients after vitrectomy for a macular
hole. They had observed that some patients
complained of small paracentral field defects despite
good postoperative results in reading and
visual acuity [13].
1.3 Clinical Implementation 9
Summary for the Clinician
■ Use of microperimety in macular holes
has been well established for years and
allows differentiation from pseudoholes.
■ Accurate determination of preferred
retinal locus and retinal sensitivity, especially
in the area surrounding the hole, is
helpful in macular hole surgery.
