Peripheral non perfusion in diabetic retinopathy

Default Peripheral non perfusion in diabetic retinopathy

 Peripheral non perfusion in diabetic retinopathy By Ameen Marashi When examining a patient with Diabetic retinopathy it is important to examine the peripheral funds specially using fluorescein angiography which tells us the perfusion status of the peripheral retina and thus can be important prognostic factor of progression of diabetic retinopathy. The peripheral retina can be either normal, areas of non ... Read More »

Diabetic Cotton wool spots

Cotton wool spots

Diabetic Cotton wool spots Accumulations of neuronal debris within the nerve fibre layer. They result from disruption of nerve axons. As cotton wool spots heal, debris is removed by autolysis and phagocytosis. Signs: Small, whitish, fluffy superficial lesions which obscure underlying blood vessels and are clinically evident only in the post-equatorial retina, where the nerve fibre layer is of sufficient thickness ...

Clinically significant macular oedema (CSMO)

Clinically significant macular oedema (CSMO)

Clinically significant macular oedema (CSMO) • Retinal thickening within 500 µm of the centre of the macula ( upper left). • Exudates within 500 µm of the centre of the macula, if associated with retinal thickening (which may be outside the 500 µm –  upper right). • Retinal thickening one disc area (1500 µm) or larger, any part of which ...

Diabetic Ischaemic maculopathy

Diabetic Ischaemic maculopathy

Ischaemic maculopathy Signs are variable and the macula may look relatively normal despite reduced visual acuity. In other cases PPDR may be present. FA shows capillary non-perfusion at the fovea (an enlarged FAZ) and frequently other areas of capillary non-perfusion at the posterior pole and periphery.

Diabetic Diffuse Maculopathy

Diabetic Diffuse Maculopathy

Diabetic Diffuse Maculopathy Signs. Diffuse retinal thickening, which may be associated with cystoid changes. Severe oedema  may render localization of the fovea impossible FA shows late diffuse hyperfluorescence which may assume a central flower-petal pattern if CMO is present.

Diabetic Focal Maculopathy

Diabetic Focal Maculopathy

Diabetic Focal Maculopathy Signs. Well-circumscribed retinal thickening associated with complete or incomplete rings of exudates FA shows late, focal hyperfluorescence due to leakage, and good macular perfusion Source:  Ophthalmology Atlas(Photos of cases) Diabetic Focal Maculopathy Read More »

Diabetic macular oedema

Diabetic macular oedema

Diabetic macular oedema is the most common cause of visual impairment in diabetic patients, particularly type 2. Diffuse retinal oedema is caused by extensive capillary leakage, and localized oedema by focal leakage from microaneurysms and dilated capillary segments.With further accumulation of fluid the fovea assumes a cystoid appearance (cystoid macular oedema – CMO). Signs. Retinal thickening is best detected by ... Read More »

Diabetic Tractional Detachment of the Macula

Diabetic Tractional Detachment of the Macula

(a)Diabetic tractional detachment of the macula. There is a thick fibrovascular membrane lying on the surface of the macula causing a tractional detachment with accumulation of a large amount of intraretinal edema. (b)Following pars plana vitrectomy with membrane peeling there is a return to a more normal macular architecture. There is still a large amount of cystic intraretinal edema present ... Read More »
