Subretinal hemorrhage with Hypofluorescence

Subretinal hemorrhage with Hypofluorescence

Subretinal hemorrhage with Hypofluorescence  is demonstrated in this patient with a ruptured retinal arterial macroaneurysm. The ability to visualize the retinal circulation overlying the blocking defect confirms the subretinal location of the hemorrhage Source: Ophthalmology Notes Ophthalmology Atlas(Photos of cases) Subretinal hemorrhage with Hypofluorescence  Read More »

Preretinal haemorrhage and Flame shaped haemorrhage

Preretinal haemorrhage an Flame shaped haemorrhage

Preretinal haemorrhage an Flame shaped haemorrhage Preretinal (Subhyaloid) hemorrhages: Clinical features: Occur either in the level of subhyaloid space between posterior vitreous face and retina or under internal limiting membrane. Localized vitreous gel detachment may occur. Horizontal blood level or boat-shaped hemorrhage is usually apparent, which obscures the underlying retina. Fluorescein angiography demonstrates blockage of underlying details in areas of ... Read More »

Irregular FAZ macular ischemia

Irregular FAZ macular ischemia

Macular ischemia The foveal avascular zone was measured angiographically in 144 subjects with diabetic retinopathy and 27 control subjects. Statistical significance was defined as P < 0.01. Quantitatively, the foveal avascular zone was significantly smaller in control eyes (median = 0.405 mm2) than in eyes with diabetic retinopathy, and smaller in eyes with background diabetic retinopathy (BDR; median = 0.737 ...

Subretinal fluid

Subretinal fluid

Subretinal fluid can also originate directly from the choroid such as in VKH (VogtKoyanagi-Harada) disease where massive primary choroidal inflammation spills over to the retina and causes profuse leakage of liquid through the retinal pigment epithelium (RPE) forming exudative retnal detachments (ERD). Other diseases that can produce ERD include sympathetic ophthalmia and posterior scleritis Source: Ophthalmology Notes Ophthalmology Atlas(Photos of cases) Subretinal ... Read More »

Exudative retinal detachments

Exudative retinal detachments

Exudative retinal detachments produce RPE changes charcterised by loss of RPE cells causing small areas of window defects as well as clumping of cells causing masking effect. This alternation of loss and clumping of RPE gives a mottled aspect on early angiographic frames due to increased transmission of background choroidal fluorescence (window effect) in some areas together with decreased transmission ...
