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 - Optic Disc

This is just me messing around during free time at work. This is a triple composite. First, the background is a composite of all of the disc photos I have shot since working at the WFUBMC Eye Center. Then I put a fundus image of an optic disc with papilledema in front of that and masked some areas.

This is actually super corny, and I am usually against stuff like this. But whatever.

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.

The Operating Room: DSEK

This is a shot taken in the operating room during a DSEK procedure.

Descemet's Stripping Endothelial Keratoplasty

This procedure is done to replace and repair the tissue of the cornea. Instead of a corneal transplant that damages many endothelial cells and takes a long time to recover from, this procedure takes a donor cornea endothelial layer and places it through a small incision, allowing less recovery time as well as a lot less damage to the corneal cells. The following image shows the step by step process, from the donor cornea in the first image, to the placement and unfolding of the donor corneal layer, to the injection of an air bubble to hold the graft in place for proper healing position.

*This same patient had a cataract removed and an IOL (Intra-Ocular Lens) inserted just minutes before the DSEK procedure.

Cataract Composite

This image is a composite of 4 images taken on the slit-lamp camera. Each separate image is called a red-reflex image, because you are lighting the posterior of the eye, and focusing on the anterior lens, so the cataract can be viewed somewhat like a silhouette. So two of the photos were at the nearest plane of sharp focus, while the other two were at the farthest plane of sharp focus. I used Photoshop to mask them together to show the full depth of the cataract.

Definition of Cataract: Opacity or cloudiness on the crystalline lens, which may prevent a clear image from forming on the retina.

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.

Oh blogger where art thou? It's been about three months since I have even looked at one of these bad boys. I decided today that I will begin posting again due to the completion of my biology classes as well as the completion of my college admissions stuff. So in other words, I'm bored.
Most of what I'll be posting from now on is likely to be relative to my internship at Wake Forest University Eye Center as an Ophthalmic Photographer. I am not going to go into depth describing what is in these images, but only simple explanations for easy understanding. I hope everyone enjoys them.
This first image is a fundus(the inside) image of my own eyes. These were taken by David Miller, a co-worker of mine and a graduate of RCC. The photos are in sequence, right eye, left eye. This is also referred to as OD(Ocular Dexter), OS(Ocular Sinister).

"Acrylic Canvas"

A canvas with mixed acrylic paint. Shot 1:1 using a Vivitar 285 and a make-shift soft box. The specular highlights were very difficult to control because of the various angles, as well as the glossiness of the paint. I love the colors though, so many more attempts in due time.

"Class Ring Emblem"

Close up of my high school class ring cross country emblem shot in studio on chrome. I liked the light on the upper body of the he/she. I shot this with speedo strobes, with the light over top shooting through a diffusion screen with fill cards below reflecting upwards. 4:1 ratio.

"Macro Cleaner"

The nozzle of a squirt bottle. I have been trying to capture a bit of action in my recent macro set-ups, so I attempted at freezing the water coming out. Therefore, I used a vivitar 285 set on manual, and fill cards for the opposite side. 2:1 ratio.

Macro: Top-Sider

My shoelace eye was the subject in this macro photograph. I lit this with two speedotron heads. One hitting a diffusion screen on the left and the other front lighting with a green gel on it. This macro ratio is about 1.8:1.

Macro: Toothpicks

Another macro photograph, this time of some wooden toothpicks. This was shot with chrome. Huh? Chrome!! Oh.. This was actually really easy to light, I just used a speedotron, pointing it downward onto the scene. The ratio is around 2.85:1, or 2.85 magnification.

"Aeshna Isosceles"

This is Aeshna Isosceles, a dragonfly. I shot this lady with the pb-6 and pb-5 bellows, two extension tubes, and a 105 micro lens. I used Speedo strobes and a homemade soft box to light her, while placing green and red reflective paper under her for accent colors.

105mm micro w/ 340mm extension


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

Over Break

Over the break, I photographed some kitchen interiors that will be used in the showroom of Apex Cabinet Company in Apex, NC. Itwas my first time lighting large interiors on location, so I learned a lot. I used 2 alien bee strobes and 2 broncolor minipuls for the overall light, and then had 2 flashes optically slaved for detailed area illumination. I used a 35mm digital, so it couldn've looked better shot large format, but I was in a hurry.

Macro: 1st attempt

This was one of my first attempt shots for our macro-photography course. I used the pb-6 bellows, two extension tubes, and the 105 mm micro lens. In all, there was 280.5 mm of extension. I set up the butterfly with a blue piece of foam board behind, which had white spots on it. I was attempting to have the sky look as if it had clouds in it.
