Objective:
To study a new technic of laser treatment of macular holes.
Methods:
21 eyes with stage II-IV macular hole were treated with Argon-green laser. Pigment epithelium in the area of the hole was whitened with spots of 100-200 microns, 100-300 mW. We expected this treatment to create a cellular proliferation that could close and contract the hole. Follow-up after treatment ranged from 3 to 24 months (mean: 9.3 months).
Results:
Within one month after treatment, the macular hole was closed in 7 eyes (33%) and partially closed in 5 eyes (24%). The visual acuity increased from 1 to 5 lignes (ETDRS chart) in 9 eyes (43%), it remained the same in 9 eyes (43%) and decreased from 1 to 2 lignes in 3 eyes (14%).
Conclusion:
Laser treatment of macular holes seems to be effective and could be proposed as an alternative to the patients who cannot be operated on by vitrectomy and gas tamponade.
