Study Notes
Diabetic Maculopathy and OCT Patterns
- Characteristic OCT pattern shows sponge-like thickening of retinal layers, indicative of diabetic maculopathy.
- Taut posterior hyaloid membrane on OCT suggests potential traction affecting the macula in diabetic maculopathy.
- Diabetic maculopathy exhibits deformations such as retinal thickening, subretinal fluid, and hard exudates.
OCT Findings and Conditions
- Serous retinal detachment is indicated by the elevation of the neurosensory retina with an optically clear space beneath.
- Full-thickness macular holes differ from lamellar holes and pseudo holes based on distinct OCT findings, particularly the presence or absence of a full-thickness defect in the retina.
- Anomalous structures may appear on OCT images, including atypical tissue or abnormal fluid collections.
OCT Imaging Characteristics
- Warm colors (red, yellow, white) represent areas of increased thickness or pathological changes in the macula.
- Cold colors (green, blue) denote reduced thickness or normal retinal characteristics in OCT imaging.
- An optically empty space, often seen in OCT imaging, indicates the presence of fluid or cysts within the retina.
Quantitative and Qualitative Analysis
- Quantitative analysis in OCT involves tracing specific retinal structures or layers to assess thickness and volume.
- Qualitative analysis reviews changes in the retinal architecture, fluid presence, and exudate patterns on OCT scans.
Conditions and Features on OCT
- Haemorrhagic Pigment Epithelial Detachment (PED) shows characteristic features such as elevation of the retinal pigment epithelium along with accompanying hemorrhage.
- Impending macular holes or foveal edema is associated with a distinct OCT pattern reflecting changes in the fovea.
- Central Serous Retinopathy on OCT imaging typically demonstrates subretinal fluid accumulation and retinal elevation, particularly at the macula.
