Drusen detection with OCT
Distinguishing between drusen types on OCT can be challenging, yet crucial. Drusen are focal extracellular deposits, rich in lipids, that accumulate between the basal lamina of the retinal pigment epithelium (RPE) and the inner collagenous layer of Bruch's membrane.
Drusen detection with OCT Distinguishing between drusen types on OCT can be challenging, yet crucial for AMD assessment. Drusen are focal extracellular deposits, rich in lipids, that accumulate between the basal lamina of the retinal pigment epithelium (RPE) and the inner collagenous layer of Bruch's membrane. They vary considerably in appearance, location, and size, ranging from 30 to 50 μm in diameter or larger when confluent. Confluent drusen form from the aggregation of hard or soft drusen. In advanced stages of age-related macular degeneration (AMD), hard drusen can coalesce into confluent plaques associated with atrophy of the RPE and photoreceptors, leading to geographic atrophy (GA). Large or confluent drusen are also associated with an increased risk of choroidal neovascularization, the hallmark of exudative (wet) AMD. The confluence of soft drusen can lead to the formation of drusenoid pigment epithelial detachment (PED). Maria Znamenska

Interpreting #Ellipsoid_Zone in #OCT
Established metrics for assessing the EZ include its integrity, lesion size, and the width/area of the retained EZ. These metrics correlate with visual acuity (VA) and other aspects of retinal function.
Interpreting #Ellipsoid_Zone in #OCT Established metrics for assessing the EZ include its integrity, lesion size, and the width/area of the retained EZ. These metrics correlate with visual acuity (VA) and other aspects of retinal function. A basic measure of EZ integrity involves a subjective assessment of whether the band is intact, disrupted, or absent. This assessment can be aided by longitudinal reflectivity profiles, which evaluate the gray value intensity axially through the OCT image. However, this method is only practical for focal assessments. To capture regional properties of the EZ, categorical grading schemes have been developed, particularly for describing EZ band disruption at the fovea in certain retinal conditions. Maria Znamenska

▪️Multiple serous detachments are apparent.
▪️FFA and OCT are consistent with the diagnosis of VKH.

#Diabetic #macular_edema is the most common cause of vision loss in those with diabetes. It results from a blood-retinal barrier breakdown, leading to fluid leakage and retinal thickening.

#CME on #OCT
Cystoid macular edema CME is the accumulation of fluid within the retina, specifically between the outer plexiform layer and the inner nuclear layer, leading to the formation of cystoid spaces in the macula.OCT is the gold standard for diagnosing and monitoring CME

Vitelliform macular dystrophy (VMD)-Best disease, is a genetic condition caused by BEST1 mutations, with a yolk-like macular lesion. OCT shows SRF & a 'shaggy' outer retina. VMD is usually bilateral & symmetrical. #Ophthalmology #Retina #VMD #BestDisease
