Abstract
PURPOSE
To determine whether improvements in microperimetry testing are associated with anatomic resolution after ocriplasmin treatment in patients with symptomatic vitreomacular adhesion (VMA)/vitreomacular traction and relatively preserved baseline best-corrected visual acuity (BCVA).
METHODS
Patients with vitreomacular traction received a single 125-μg intravitreal ocriplasmin injection and were followed longitudinally for 6 months with optical coherence tomography, BCVA testing, and microperimetry. Visual function changes were compared between eyes with and without VMA resolution on optical coherence tomography.
RESULTS
Eleven of 16 eyes (68.8%) achieved VMA resolution after treatment. Mean baseline BCVA was relatively good (79 ± 3 Early Treatment Diabetic Retinopathy Study letters; 20/52); no patients had a ≥2-line improvement in BCVA over the 6-month follow-up period. In the group with VMA resolution, mean retinal sensitivity significantly increased in the central 4° (15.2 ± 1.9 dB vs. 18.9 ± 0.7 dB, P < 0.001) when comparing baseline and final follow-up microperimetry testing. No change in mean retinal sensitivity was found in the group without VMA resolution.
CONCLUSION
Microperimetry demonstrates a significant gain in retinal sensitivity, particularly in the central 4° area, in eyes with anatomic resolution after treatment of vitreomacular traction with intravitreal ocriplasmin injection, even when no significant gain in BCVA is seen.
