Fundus Photography - PDR & Asteroid Hyalosis

This is a composite of two fundus images taken of THE SAME patient, a 39 yr. old African female. The left image is ocular dexter and the right image is ocular sinister. I just thought the differences between the two were pretty interesting.

The right eye(left image) shows proliferative diabetic retinopathy(PDR), while the left eye(right image) shows extreme asteroid hyalosis.

Fundus Photography - Malignant Melanoma

Sorry for the delay in posting, it has been very busy at my internship, and I have been trying to sort everything out for graduation as well.

Anyways, here is an image of a malignant melanoma attached to the retina of the right eye in a 20 yr. old Caucasian male. Another was found in the left eye, but was about 1/20th the size of this one. If you look close enough you can really see the detail within this tumor. The retina itself is out of focus, but only because I wanted focus on the tumor.

Slit Lamp - Keratic Precipitates

This is a photograph of Keratic Precipitates located on the inner endothelial layer of the cornea. This patient had a bad reaction to silicon oil used after a cataract removal and these precipitates formed.

KERATIC PRECIPITATES: Inflammatory cells and white blood cells from the iris and ciliary body that enter the aqueous and adhere to the innermost corneal surface (endothelium).

What is seen where the lens should be is not actually a cataract, because that was removed, it is actually part of the reaction to the silicon oil building up anterior the lens.

Slit Lamp - Post Traumatic Scleritis

Another Slit-lamp image taken of a patient with Scleritis after trauma. Most patients we shoot on the Slit-lamp are photo-phobic (extremely sensitive to light) because of their anterior pathology, and it is not often you have a cooperative patient. They always pull away after every shot and complain. For this patient, we had to have three people in the room; myself, taking the photos, and two technicians forcing the patients head forward and pulling the eyelids open.
Also, sometimes the doctors will come in the camera room and want to watch, which was also the case for this patient, who was to immediately go into surgery after I finished the photographs. No pressure.

Slit Lamp - Pterygium

Below is an image of what is called Pterygium. The "P" is silent.

PTERYGIUM: An abnormal, wedge-shaped growth on the bulbar conjuctiva, often related to sun irritation.

Macular Nevus

This is a nevus located beneath the macula in the choroid layer of the eye.

NEVUS: (Mole) Small, flat, usually pigmented benign tumor made up of specific cells called nevus cells; found in skin and eye tissues.

Pyogenic Granuloma

This is an external shot of a pyogenic Granuloma. A breakdown of what exactly this means:

Pyogenic: Producing Pus.

Granuloma: Dense collection of cells consisting of various inflammatory types.

THEREFORE: This is a growth of epitheliod (skin) cells, filled with pus.

"Hemangioma"

This was another "first attempt" in the macro scene. The image is of epidermis on the posterior 3rd phalange. I used the PB-6 and PB-5 Bellows and two extension tubes. In all, there was 470 mm of extension and an 85mm lens, creating roughly a 10:1 ratio. The red granules in the skin are hemangioma, or marks caused by blood vessels close to the skin. I used Speedotrons pumped to F/64
