Fluid-gas exchange an effective alternative for open macular holes after vitrectomy
Outpatient fluid-gas exchange was an effective alternative for eyes with open macular holes after vitrectomy, a study found.
Anatomic success was attained in 32 eyes (89%) between 1 and 3 weeks following fluid-gas exchange. Type 1 closure was attained in 22 eyes (61%), type 2 closure was attained in 10 eyes (28%) and no closure was attained in four eyes (11%).
LogMAR best corrected visual acuity for type 1 closure improved from 1.66 to 0.84; the gain was significant (P < .001). LogMAR BCVA for type 2 closure improved from 1.77 to 1.52, which was also significant (P = .05).
All eyes that did not attain hole closure had a stage IV macular hole and an average hole size greater than 1000 µm.
Following fluid-gas exchange, retinal detachment was reported in two eyes (6%), elevated IOP was reported in three eyes (8%) and cataracts developed in 34 eyes (94%); however, all eyes were corrected.
