Ocular toxoplasmosis
35yo
Ocular toxoplasmosis is characterized by a pathognomonic lesion, typically presenting as a focal, necrotizing retinochoroiditis. This lesion is often accompanied by adjacent old chorioretinal scars and active inflammation. Fundus imaging reveals a white or yellowish focus of retinal necrosis with surrounding inflammation. Fluorescein angiography (FA) and Optical Coherence Tomography (OCT) […]

Proliferative sickle cell retinopathy
46yo
Proliferative sickle cell retinopathy (PSCR) is characterized by several distinct retinal features. Sea-fan neovascularization represents abnormal new blood vessel growth in the peripheral retina. Peripheral ischemia, caused by occluded blood vessels, leads to areas of retinal non-perfusion. Black-sunburst lesions are hyperpigmented areas resulting from previous hemorrhages and pigment migration. These […]

Ocular albinism
52yo
Ocular albinism often presents with foveal hypoplasia, characterized by an underdeveloped fovea. Optical Coherence Tomography (OCT) reveals the absence of a foveal pit and a continuous inner retinal layer. This lack of foveal specialization is a hallmark of the condition and contributes to visual acuity deficits. Advanced imaging techniques, including […]

Diabetic Macular Edema
37yo
Diabetic macular edema (DME) with longstanding subretinal fluid (SRF) can lead to hyperautofluorescence on fundus autofluorescence (FAF) imaging. This hyperautofluorescence indicates chronic damage and accumulation of lipofuscin in the retinal pigment epithelium (RPE). It is a potential biomarker of worse prognosis, as it suggests persistent retinal stress and damage. #DME […]

AMD: Drusenoid PED
74yo
In age-related macular degeneration (AMD), drusenoid pigment epithelial detachment (PED) can be assessed using advanced retinal pigment epithelium (RPE) analysis. This analysis, performed with Optical Coherence Tomography (OCT), provides detailed imaging of the RPE and the drusenoid material. It helps in evaluating the structural integrity of the RPE, the extent […]

Neovascular AMD
77yo
The early stages of neovascular age-related macular degeneration (AMD) can be challenging to diagnose. Optical Coherence Tomography (OCT) and Optical Coherence Tomography Angiography (OCTA) are valuable tools in this regard. OCT provides detailed cross-sectional images of retinal layers, revealing subtle fluid accumulation and retinal thickening. OCTA detects abnormal blood flow, […]

AMD: Drusenoid PED
74yo
In age-related macular degeneration (AMD), drusenoid pigment epithelial detachment (PED) can be effectively visualized using the green channel in color fundus photography. The green channel enhances the contrast, highlighting the drusenoid material and providing detailed imaging of the PED. This helps in assessing the extent and progression of the disease. […]

Foveal hypoplasia
32yo
Foveal hypoplasia grade 1a is characterized by the absence of a foveal pit while retaining the inner retinal layers at the fovea. Optical Coherence Tomography (OCT) reveals the absence of the typical foveal depression and a continuous inner retinal layer. Optical Coherence Tomography Angiography (OCTA) shows an abnormal vascular pattern, […]
-
Diabetic macular edema
37yo
Diabetic retinopathy is characterized by increased vascular permeability, leading to leakage of blood and fluid into the retina. Fluorescein angiography (FA) is used to assess this permeability, revealing areas of leakage, microaneurysms, and also neovascularization. FA helps in evaluating the extent of retinal damage and guiding treatment decisions. #DiabeticRetinopathy #VascularPermeability […]

Peripheral Hemorrhagic Exudative Chorioretinopathy
72yo
Peripheral hemorrhagic exudative chorioretinopathy (PHECR) is a retinal condition characterized by peripheral hemorrhages and exudation. In the early stage, small hemorrhages and exudates are present. Fundus autofluorescence (FAF) using the green channel can highlight areas of exudation and hemorrhage. Optical Coherence Tomography (OCT) provides detailed cross-sectional images, revealing the extent […]

Best’s vitelliform dystrophy
36yo
Best’s vitelliform dystrophy is characterized by the presence of vitelliform lesions in the macula. Fundus autofluorescence (FAF) imaging shows increased autofluorescence corresponding to the accumulation of lipofuscin within the lesion. Optical Coherence Tomography (OCT) provides cross-sectional images, revealing a hyperreflective lesion between the retinal pigment epithelium (RPE) and the photoreceptor […]

Hypertensive retinopathy
63yo
Hypertensive retinopathy is characterized by changes in the retinal vasculature due to high blood pressure. Key features include arteriolar light reflex, where the central light reflex on arterioles is enhanced and appears broader. Arteriovenous (AV) crossing changes, also known as AV nicking, occur when thickened arterioles compress venules at crossing […]
