    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.
