A 60-year-old female with a Stage III macular hole in her left eye underwent standard 25G pars plana vitrectomy. Visual acuity before and after surgery and anatomic results, using colour fundus imaging and optical coherence tomography scan, were followed up for a period of 2 months.
On the seventh postoperative day, residual TA deposition was observed inside the closed macular hole. The TA crystal appeared as a round hyper-reflective area on optical coherence tomography scan. Two months after the surgery, no residual TA was found and the macular hole remained closed. No hyper-reflective spot detected on the optical coherence tomography scan. The best-corrected visual acuity of the left eye improved to 7/10.
Residual TA in the macular hole after vitrectomy did not interfere with macular hole repair either anatomically or functionally.
