SHUNT

at 10:00 there's the end of shunt into the anterior chamber.  This shunt is a bypass to keep the pressure in the eye.  This is a blind eye from an ischemic event (stroke in the eye).  You can see he has a thick cataract as well in that eye.  This eye has no light perception.  Pressure is at 22mmHg which is good for him.

TORTUOUS RETINAL BLOOD VESSELS

Just a really cool picture I wanted to post.  Normally the retinal blood vessels are straight, like the photo below.

ATYPICAL PTERYGIUM

What makes this pterygium special is the petal-like pattern of the blood vessels, like we may see in a squamous cell papilloma.

CHOROIDAL NEVUS

MACULAR DRUSEN

Macular Scar

This is the left macula of a 25 year old male who has had this macular scar since birth. His visual acuity is 20/20.  

Optic Pit

This is a congenital anomaly where the optic nerve has a pit in it.  It doesn't affect central vision but it can cause non-progressive visual field defects, detected only with a automated threshold visual field testing.  It doesn't cause any problems except about half of these patients around 30 years old develop an episode of fluid under their central retina that mildly to moderately decreases vision.  This episode resolves itself 25% of the time within 3 months, or can be treated successfully with laser or vitrectomy procedure. 

CONGENITAL CATARACTS

These cause glare at night and the inability to get perfect 20/20 vision. 

NEVUS-LIKE MACULAR LESION

The dark area in the center is near the center of the vision and correlates with a blind spot in the patient's vision that she says is enlarging.  

COMMOTIO RETINAE

This is like a bruise on the retina.  It does effect vision in the area that corresponds to the "bruise".  This particular patient got hit the day before with a spiked volleyball. 

CONCRETION

Calcium deposits under the conjunctiva on the inside of the eyelids.  They are not dangerous and usually asymptomatic.
