Summary
Macular holes can form without vitreous traction, suggesting spontaneous umbo dehiscence or cystic degeneration as potential causes. This challenges traditional theories on macular hole pathogenesis.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Pathogenesis of Macular Holes
Background:
- Macular hole formation has garnered increased attention with therapeutic advancements.
- This study investigates three cases of macular holes presenting in atypical settings.
Observation:
- Three patients developed macular holes 10 months to 5.5 years post-vitrectomy.
- In all cases, the cortical vitreous layer was absent around the macula during macular hole surgery.
- No operculum or residual cortical vitreous was observed in these cases.
Findings:
- Macular holes were successfully treated with improved visual acuity in all patients.
- The absence of cortical vitreous and delayed onset suggest alternative etiologies.
- Cases occurred long after vitreous removal without evidence of residual cortical vitreous.
Implications:
- Macular hole etiology may involve spontaneous umbo dehiscence, not solely vitreous traction.
- A cystic degenerative process is proposed as a mechanism for both typical and atypical macular holes.
- Findings may refine understanding of macular hole pathogenesis and treatment strategies.
