Fundus photos showing sheathing of the major and minor vasculature. Fluorescein angiography with small vessel vasculitis with diffuse temporal non-perfusion.

Myopic degeneration patches of severe retinal and choroidal atrophy, lacquer cracks, a tilted disc and lattice degeneration.

Pigmented lesion in the peripapillary area with lacunae suggesting chronicity.

Fundus photo with a nasal peripapillary sub retinal vascular complex surrounded by exudation. OCT with pigment epithelial detachment and associated sub-retinal fluid. ICG angiography makes the diagnosis clear with a hypercyanescent polyp in the choroid.

External photo depicting characteristic yellow papules, or p'eau d'orange, on the neck. Fundus photos with angioid streaks (yellow arrows).

The patient presented with a RAM and sub-macular hemorrhage. Treatment was with pars plana vitrectomy, sub-retinal tissue plasminogen activator injection and 26% SF6 gas. The hemorrhage resolved with some photoreceptor changes, but no fibrosis and the patient regained 20/40 vision.

A 40-year-old female with headaches, hearing loss and a superior scotoma in the right eye. Fundus photo with multiple inferior branch retinal artery occlusions. Angiography with non-filling of the inferior arterioles and capillary dropout in the area of the infarct. MRI showed scatter FLAIR lesions…

The traction retinal detachment has taken on a napkin ring configuration.

The curvilinear breaks in Bruch’s membrane and found with some mild associated sub-retinal hemorrhage. Infrared image depicts the patterns of rupture.

This patient was diagnosed with genetic testing to have the hereditary vitreoretinopathy, Wegner's Syndrome. The abnormal vitreoretinal interface leads to a focal tractional retinal detachment of the macula. Post-operative photo and OCT show resolution of the detachment after vitrectomy.

In this module, we will look at:




Anatomy of the Retina, Vitreous, and Choroid


Imaging in the Retina


Age-Related Macular Degeneration


Central Retinal Vein Occlusion


Central Retina Artery Occlusion


Retinal Tears / Detachments


Retinitis Pigmentosa

In this condition, vasculitis of both arteries and veins, with translucent exudation, gives a similar appearance to the frosted branches of a tree. (Yellow arrow). Superior nasally, there is also the classic retinal whitening with retinal hemorrhages, also known as a “pizza pie fundus”.

The pseudocyst (yellow arrow) can be a signal that the retinal detachment is chronic. The ultrasound helps to clearly define the fluid filled cavity. It is thought that these are formed by schisis cavities in the outer plexiform layer. If closure of the primary break is not possible, or if the pseu…
