Follow-up of the vein occlusion patient from previous page: The BCVA was 20/30 OD and 20/15 OS. Ophthalmoscopy revealed large cups due to glaucoma OU and an epiretinal membrane 0D>0S. The vein occlusions OD appear to be resolving quite well but the patient is still symptomatic in the right eye. He complains about persistent
Image Gallery - Vein Occlusions The images above are from a patient who had a CRV occlusion OS more than two decades ago and a recent inferior hemi-central retinal vein occlusion OD. An additional superior nasal vein occlusion months earlier gives the appearance of a 3 quadrant vein occlusion OD.(See Case 5- Vein Occlusion)
Figure A - Composite view of the right eye. Figure B - Magnified view of right eye. Figure C - Magnified view of right eye using the green separation. Asymptomatic 36 year old female presented with a far peripheral anastomosis in the right eye temporally (as well as a small hemorrage above the AV abnormality).
20 year old female presented with uni-ocular AV malformation in the inferior retina OS. In addition to the retinal AV malformation, the patient had multiple AVMs near the hypothalamus, and thus far has undergone two major neurosurgical procedures to close some of the abnormal vessels. Blood "pools" in large AVMs and "steals" blood
The FA angiogram reveals delayed filling of the veins in the superior temporal quadrant, secondary to venous occlusive disease.
In this congenital AVM, the presence of hemorrhages as noted above, suggests recent venular occlusion disease. Branch retinal vein occlusions, among other complications, are characteristic of this anomaly. (See page 16).
The optomap® green separation image above highlights findings anterior to the retinal pigment epithelium(RPE) such as blood vessel anomalies and scattered hemorrhages.
The optomap® color fundus image above represents a panoramic view emphasizing the superior temporal quadrant of the left eye.
As depicted in the horizontal sections above, the PIL is present and normal under the fovea in each eye. In vein occlusions1 as well as other retinal abnormalities, the VA can often be predicted based upon the status of the PIL.2 In this case, the normal PIL predicts the 20/20 VA in each eye.
The green box is 6 mm x 6 mm and contains 128 horizontal sections. The retina is elevated around the AV malformation. “Shadowing" of deeper structures prevent detailed assessment of the PIL and other layers. When both the PIL and RPE are not present, no conclusion can be reached about the integrity of
