What level of the retina do dot-blot hemorrhages occur compared to flame-hemorrhages?
Dot-blot hemorrhages tend to occur deeper in the retina where the cells run vertically. You associate these hemorrhages mostly with background diabetic retinopathy.
Flame hemorrhages, however, are more superficial in the ganglion nerve fiber-layer, and are associated with hypertension and venous stasis.
very nice visual explanation!love your site and your informal way of writing!
So why doesn’t Diabetes affect the more superficial capillaries and thus also cause flame-shaped hemorrhages?
And conversely, why doesn’t Hypertension or venous stasis damages the deeper retinal capillaries and cause dot hemorrhages?
