PURPOSE: To determine whether intravitreal injection of autologous plasmin enzyme (APE) is effective in vitreomacular traction syndrome (VMTS) by improving visual acuity and restoring macular morphology.
METHODS: A prospective study of 11 consecutive patients diagnosed with VMTS in the Ophthalmology Department from January to May, 2011.
INCLUSION CRITERIA: best corrected visual acuity (BCVA) less than 0.5, and vitreomacular attachment in foveal area resulting in macular thickness>250 microns diagnosed by optical coherence tomography (Cirrus OCT, Carl Zeiss Meditec, Inc, Oberkochen, Germany).
EXCLUSION CRITERIA: active proliferative diabetic retinopathy, axial myopia>26mm, vitrectomy, glaucoma, previous intravitreal injections and previous rhegmatogenous detachment. One to 3 monthly intravitreal injections of 0.2ml of APE were applied, interrupting if posterior vitreous detachment was attained. Wilcoxon's test was used for statistical analysis.
RESULTS: A total of 12 eyes of 11 patients were treated. A complete posterior vitreous detachment was achieved in 4 (33%) eyes at the end of the study, 2 of them with one injection, and 2 with 3 monthly injections. Improvement of BCVA was statistically significant (P=.017) and the decrease in central macular thickness also was statistically significant (P=.016). There was only one complication: intraocular hypertension after injection that subsided with a new paracentesis.
CONCLUSIONS: Intravitreal APE injections avoided vitrectomy in VMTS in one in every 3 patients.
