Summary
Paracentral retinal defects, a rare complication after macular hole surgery, were observed using spectral optical coherence tomography. These defects, potentially caused by internal limiting membrane peeling, tended to decrease in size over time.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Diagnostic Imaging
Background:
- Macular hole surgery aims to restore vision by closing the retinal defect.
- Complications can affect visual outcomes.
- Optical coherence tomography is crucial for visualizing retinal structures.
Purpose of the Study:
- To present paracentral defects after macular hole surgery using spectral optical coherence tomography (SOCT).
- To discuss the influence of these defects on functional outcomes.
Main Methods:
- Case report of a patient with paracentral retinal defects post-macular hole surgery.
- Utilized a spectral optical coherence tomography device with 3 μm axial resolution.
- Performed 3D scans of the macula and HRT2 macular module scans.
Main Results:
- A 70-year-old male patient developed paracentral retinal defects one week after macular hole surgery.
- Best-corrected visual acuity remained 0.2 for two years post-surgery.
- Observed a tendency for the paracentral defects to decrease in size.
Conclusions:
- Full-thickness paracentral retinal holes are a rare complication of vitrectomy.
- Internal limiting membrane peeling is suggested as the cause of these defects, not direct trauma.
