Summary
Tilted disk syndrome can cause new T-shaped pigmentary changes near the inferior staphyloma. These findings may suggest chronic leakage, adding to known complications of this condition.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Medical Diagnostics
Background:
- Tilted disk syndrome is associated with various ocular complications, particularly in the inferior staphyloma region.
- Previous complications include macular changes, neovascularization, and retinal detachment.
Observation:
- This study identified a novel complication in eyes with tilted disk syndrome: T-shaped pigmentary changes.
- These changes were observed radially from the inferior staphyloma border in 6 patients.
- The pigmentary alterations presented as linear, triangular, or oval areas.
Findings:
- All 6 patients exhibited characteristic T-shaped pigmentary changes.
- Three patients had a history of subretinal leakage mimicking central serous chorioretinopathy.
- Fluorescein angiography was used to document these findings.
Implications:
- T-shaped pigmentary changes should be recognized as a potential complication of tilted disk syndrome.
- Their presence may indicate underlying chronic leakage near the staphyloma.
- This adds to the spectrum of retinal abnormalities seen in tilted disk syndrome.
