Enhanced depth imaging spectral domain optical coherence tomography (EDI-OCT) effectively visualized a choroidal macrovessel, revealing a thickened choroid and outer retinal deformation. This imaging helps differentiate it from similar conditions.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Choroidal macrovessels are rare vascular anomalies.
- Accurate imaging is crucial for diagnosis and differentiation from other conditions like ophthalmomyiasis.
Observation:
- A 42-year-old male presented with metamorphopsia.
- Multimodal imaging, including enhanced depth imaging spectral domain optical coherence tomography (EDI-OCT), was employed.
Findings:
- EDI-OCT revealed a thickened choroid and deformation of the ellipsoid zone and choroidal-scleral junction.
- En face spectral domain optical coherence tomography confirmed an anomalous choroidal vessel.
- A serpentine subretinal pattern was noted, with a large diameter vessel visible after red filter application.
Implications:
- EDI-OCT and en face OCT are valuable tools for demonstrating choroidal macrovessels.
- These techniques aid in distinguishing choroidal macrovessels from conditions with similar presentations.
- Understanding choroidal features associated with macrovessels improves diagnostic accuracy.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
