Purpose:
To report delayed improvement in macular hole closure configuration from Type 2 to Type 1 occurring months after internal limiting membrane peeling in two patients with macular hole.
Methods:
Case 1 underwent surgery for a post-traumatic macular hole. Case 2 underwent surgery for an idiopathic macular hole.
Results:
Six weeks after surgery, Type 2 macular hole closure was documented by optical coherence tomography in both cases. Months later, spontaneous conversion of closure to Type 1 associated with visual gain was observed.
Conclusion:
Delayed, spontaneous conversion of Type 2 closure to Type 1 closure can occur several months after surgery for traumatic and idiopathic macular holes. This may be associated with improved visual outcomes.
