Acquired Vitelliform Lesion
Acquired Vitelliform Lesions (AVL) are characterized by subretinal yellowish deposits and can be assessed using fundus autofluorescence (FAF). FAF imaging shows hyperautofluorescence in the lesion area due to lipofuscin accumulation. Over time, hypoautofluorescence may appear as the retinal pigment epithelium (RPE) degenerates, making FAF essential for monitoring disease progression. #AVL #FAF #Hyperautofluorescence #Lipofuscin #RPE…
Low integrity retinal attachment
Retinal reattachment in the wrong position can occur following surgery for retinal detachment, and fundus autofluorescence (FAF) can reveal hyperautofluorescent lines where the retinal vessels originally lay. These lines represent areas of misalignment and retinal pigment epithelium (RPE) stress, providing insight into the surgical outcome and potential functional impact. #RetinalReattachment #FAF #Hyperautofluorescence #RetinaSurgery…
Optic disc drusen
Optic disc drusen are calcified deposits within the optic nerve head, often visible on fundus autofluorescence (FAF) as hyperautofluorescent spots. FAF imaging enhances the detection of drusen by highlighting their autofluorescent properties, aiding in differentiation from other optic nerve abnormalities and in monitoring potential complications like visual field defects. #OpticDiscDrusen #FAF #Hyperautofluorescence #OpticNerve #RetinaImaging #retina…
Diabetic Macular Edema
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 #SubretinalFluid #Hyperautofluorescence #FAF #Biomarker #WorsePrognosis…
RRD: Giant retinal tear
Giant retinal tears can be assessed using fundus autofluorescence (FAF), which reveals the previous location of retinal vessels as hyperautofluorescent lines. These lines indicate where the retinal vessels were detached from the underlying retinal pigment epithelium, aiding in the evaluation of the extent of the tear and guiding surgical repair. #GiantRetinalTear #FAF #Hyperautofluorescence #RetinaImaging #retina #oftalmo #ophthalmology…
Pathologic myopia
Pathologic myopia presents distinctive features on Fundus Autofluorescence (FAF) imaging. Blue FAF shows moderate hyperautofluorescence in the region of the posterior staphyloma, while green FAF reveals marked hypoautofluorescence in areas corresponding to chorioretinal atrophy plaques. These differences highlight various aspects of retinal and choroidal changes in pathologic myopia. #PathologicMyopia #FAFBlue #FAFGreen #Hyperautofluorescence…
