EYES II

Question 1

RED SPOTS AND STREAKS IN THE FUNDI

Develops when blood escapes into the potential
space between the retina and vitreous. This hemorrhage is typically larger than retinal hemorrhages. Because it is anterior to the retina, it obscures any underlying retinal vessels. In an erect patient, red cells settle, creating a
horizontal line of demarcation between plasma above and cells below.

Causes include a sudden increase in intracranial pressure.

Answer 1

preretinal hemorrhage

Question 2

RED SPOTS AND STREAKS IN THE FUNDI

small rounded slightly irregular red spots that are sometimes called blot hemorrhages

diabetes is a common cause

Answer 2

deep retinal hemorrhage

Question 3

RED SPOTS IN THE FUNDUS

Tiny, round, red spots commonly seen in and around the
macular area. They are minute dilatations of very small retinal vessels; the
vascular connections are too small to be seen with an ophthalmoscope. A
hallmark of diabetic retinopathy.

Answer 3

microaneurysms

Question 4

Red spots and streaks in the fundi

Refers to the formation of new blood vessels. They are
more numerous, more tortuous, and narrower than neighboring blood vessels
in the area and form disorderly looking red arcades. A common feature of the
proliferative stage of diabetic retinopathy. The vessels may grow into the
vitreous, where retinal detachment or hemorrhage may cause loss of vision.

Answer 4

neurovascularization
