Summary
Pseudoxanthoma elasticum (PXE) diagnosis is aided by advanced imaging. Fundus autofluorescence and ICG angiography reveal subtle retinal findings missed by ophthalmoscopy, improving PXE evaluation.
Area of Science:
- Ophthalmology
- Medical Imaging
- Genetics
Background:
- Pseudoxanthoma elasticum (PXE) is a rare systemic disorder affecting elastic tissues.
- Ocular manifestations of PXE are crucial for diagnosis but can be subtle.
- Ophthalmoscopy may not always detect early or faint retinal changes in PXE.
Observation:
- A case report details a PXE patient with initially subtle fundus findings.
- Fundus autofluorescence (FAF) imaging and indocyanine green (ICG) angiography were employed.
- Distinct retinal features were observed with FAF and ICG angiography.
Findings:
- FAF imaging highlighted pathology at the retinal pigment epithelium level.
- ICG angiography revealed abnormalities in Bruch's membrane.
- Combined imaging modalities offered complementary visualization of PXE-related changes.
Implications:
- FAF and ICG angiography enhance the detection of PXE-related retinal pathology.
- These advanced imaging techniques may improve the diagnostic accuracy for PXE.
- The combined use of FAF and ICG angiography is valuable for comprehensive PXE patient evaluation.
