Macular pseudohole
Macular pseudohole is characterized by a steepened foveal contour without a full-thickness defect. On Optical Coherence Tomography (OCT), it shows a narrow, deep foveal pit with intact outer retinal layers, typically caused by a contractile epiretinal membrane (ERM). Differentiating it from a true macular hole is essential, as visual prognosis and management differ significantly. #MacularPseudohole #ERM #OCT #FovealContour #RetinaImaging #retina…
MacTel type 2
In macular telangiectasia type 2 (MacTel), the OCTA depth-enhanced map improves visualization of vascular alterations across different retinal layers. It highlights capillary rarefaction and telangiectatic vessels, particularly in the deep capillary plexus and outer retina. This tool enhances diagnostic accuracy and monitoring of neovascular complications in MacTel. #MacTel #OCTA #DepthEnhancedMap #RetinalVascularChanges #RetinaImaging #retina #oftalmo…
Choroidal nevus
Choroidal nevus is best visualized using near-infrared reflectance (NIR) imaging. Its appearance may vary: it can be hyperreflective in confocal systems or hyporeflective in non-confocal imaging, depending on the imaging modality and melanin density. NIR enhances contrast for detecting and monitoring nevi, especially when they are not clearly visible on color fundus photography or FAF. #ChoroidalNevus #NIR #NearInfraredReflectance #RetinaImaging…
Ocular toxoplasmosis: Chorioretinitis scars
In ocular toxoplasmosis, chorioretinitis scars can reveal underlying structures such as the posterior long ciliary artery and nerve. These become visible due to the localized atrophy of the retina, retinal pigment epithelium (RPE), and choroid, allowing clearer visualization of the deeper scleral and vascular structures. #Toxoplasmosis #ChorioretinitisScar #PosteriorCiliaryArtery #RetinaImaging #FAF #ChoroidalAtrophy #retina…

Macular telangiectasia type 2
Macular Telangiectasia Type 2 (MacTel 2) can be monitored with blue light reflectance imaging, which highlights areas of retinal degeneration and structural changes. Over a 1-year follow-up, an increase in the hyperreflectant area indicates disease progression, reflecting the expansion of retinal abnormalities. This imaging modality is crucial for tracking disease evolution. #MacTel2 #BlueLightReflectance #RetinaImaging #DiseaseProgression…
Macular telangiectasia type 2
In Macular Telangiectasia (MacTel), blue light reflectance imaging is effective for identifying early retinal changes. It enhances the visualization of macular pigment loss and plexiform layers abnormalities before identifiable using other imaging modalities. This non-invasive technique is invaluable for detecting and monitoring MacTel in its initial stages. #MacTel #BlueLightReflectance #EarlyDetection #RetinaImaging #PhotoreceptorChanges…
Congenital Hypertrophy of the Retinal Pigment Epithelium
Congenital Hypertrophy of the Retinal Pigment Epithelium (CHRPE) appears as a flat, highly pigmented lesion on fundus examination. On fundus autofluorescence (FAF), CHRPE typically shows hypoautofluorescence. This imaging modality helps confirm the diagnosis and monitor for changes over time. #CHRPE #FAF #Hypoautofluorescence #RetinaImaging #PigmentedLesion #retina #oftalmo #ophthalmology #oftalmologia…

BRVO and asteroid hyalosis
Branch Retinal Vein Occlusion (BRVO) and asteroid hyalosis can coexist, posing challenges in retinal imaging. Asteroid hyalosis, characterized by calcium-lipid deposits in the vitreous, can obscure fundus details. #BRVO #AsteroidHyalosis #RetinaImaging #OCT #FA #RetinalVeinOcclusion #retina #oftalmo #ophthalmology #oftalmologia #oftalmología #ophtalmologie #офтальмологія #офтальмология #οφθαλμολογία #retinography2024 #CIRRUS6000 #CLARUS700…
ERM formation
Idiopathic epiretinal membrane (ERM) formation can occur years after cataract surgery due to changes in the vitreoretinal interface. Blue light reflectance imaging enhances the visibility of ERM, highlighting subtle structural details and providing clear visualization of its extent. This imaging modality is valuable for monitoring ERM progression and planning potential surgical intervention. #ERM #CataractSurgery #BlueLightReflectance #RetinaImaging…
BRVO: Macula sparing
Branch retinal vein occlusion (BRVO) sparing the macula often remains asymptomatic, as central vision is preserved. These cases are typically identified incidentally during routine fundus examination or imaging. Management usually involves observation unless complications like peripheral ischemia or neovascularization develop, requiring interventions such as laser photocoagulation. #BRVO #AsymptomaticBRVO #PeripheralIschemia #RetinaImaging #retina…
