Purpose: To report two cases of secondary eccentric macular holes that developed following vitrectomy and present their outcomes.
Methods: Retrospective, observational case report.
Case description: A 69-year-old woman and a 57-year-old man developed secondary paracentral retinal hole following vitrectomy surgery for stage 4 macular hole and proliferative diabetic retinopathy respectively. In Case 1, the hole was left untreated, whereas in Case 2, laser photocoagulation was done around the paracentral retinal hole. In both cases, spontaneous closure of the paracentral retinal holes was noted 12 weeks and 3 weeks after presentation respectively.
Conclusion: Secondary eccentric retinal holes are extremely rare following vitrectomy. The pathogenesis of macular holes in our cases is most consistent with contraction of the residual internal limiting membrane or preretinal fibrous tissue. Spontaneous closure of small eccentric retinal holes can occur as well which to the best of our knowledge has not yet been reported in literature.
