⁴S. Demirel Üniversitesi, Tıp Fakültesi, Göz Hastalıkları A.D., Isparta, Asist. Dr. Purpose: To evaluate anatomic and functional results of pars plana vitrectomy in the treatment of macular hole.
Material and Methods: We retrospectively reviewed 19 eyes of 19 patients (12 women, 7 men; mean age 63.5 years) with macular hole that underwent pars plana vitrectomy in Retina section of Department of Ophthalmology at Süleyman Demirel University Medical School Hospital between January 2003 and March 2006. Classification (Gass) of macular hole was made according to biomicroscopic findings. Indocyanine green was used in 7 eye (37%), trypan blue in 7 eye (37%), triamcinolone acetonide in 5 eye (26%) to ease the peeling of internal limiting membrane, and C₃F₈ gas (14%) was left intravitreally as a tamponade. The anatomic success was judged by final postoperative macular hole status and functional success was judged by final postoperative visual acuity.
Results: Preoperatively, 3 eyes had stage 2 (16%), 9 eyes had stage 3 (48%), 7 eyes had stage 4 (37%) macular hole. Average follow-up was 12.2 moths (3 to 26 months). Visual acuity improved in 12 eyes (64%), remained same in 4 eyes (21%), and decreased in 3 eyes (16%). Visual acuity worsened in 3 eyes with non-closure macular hole (16%); Retinal detachment developed in one of these eyes one month following the first procedure and second pars plana vitrectomy was needed to reattach the retina (6%). Other 2 eyes that ended up with anatomic failure had stage 4 macular hole preoperatively (11%).
Conclusion: Pars plana vitrectomy, internal limiting membrane peeling and C₃F₈ tamponading in the treatment of macular hole allow high anatomic and functional success rate in our patients. Keywords : Macular hole, pars plana vitrectomy
