Purpose:
To report a case of macular pseudohole (MPH) development after sustained-release dexamethasone intravitreal implant for chronic macular edema due to central retinal vein occlusion (CRVO).
Methods:
A 70-year-old man with cystoid macular edema (CME) due to CRVO underwent sustained-release dexamethasone intravitreal implant. En face optical coherence tomography (OCT) was performed before and after treatment.
Results:
One month after dexamethasone intravitreal implant, best-corrected visual acuity (BCVA) improved from 1.0 to 0.5 logMAR. At 2 months, BCVA decreased from 0.5 to 1.3 logMAR. En face OCT detected the development of MPH due to exacerbation of centripetal vitreomacular transverse tractional forces on the overlying retina.
Conclusions:
Macular pseudohole seems to be a complication of intravitreal therapy in patients with coexisting vitreomacular traction. En face OCT gives useful information to understand the mechanism of MPH development after sustained-release dexamethasone intravitreal implant.
