I've posted a few times on this but this is the first patient in my practice that wanted to change medications to get her eyelashes to grow.  The right eye has been on Lumigan for five or six months and the left eye is well-controlled following SLT.  The patient wants to start using Lumigan in her left eye just for the side-effect.  Luckily, she isn't having any periorbital skin pigmentation or iris changes.

Flomax cataract cases   
Man, I've had a lot of these recently.  The first photo shows a case from last month where I needed SIX hooks to keep the iris in place, and that was with a subincisional hook to control the iris below the wound.  You can still see the hexagonal pupil here but it has since resolved to a round pupil.  The second photo is straight through the microscope eyepiece with a digital camera, just to see if it could be done; I placed four hooks in a diamond configuation but had to add one under the paracentesis.

small incision levator advancement (in office)   
Dr. Hormozy taught me how to do this in my residency (drhormozy.com).  In the office, you make a 3mm incision at the upper tarsal border, dissect superiorly until you can grasp the levator with forceps, and then suture it to the lower tarsus.  The problem with the small single incision is that you end up with a "peak" centrally in the eyelid.  This patient's other eyelid has a natural "peak" so she is a good candidate; also, she doesn't want to go to the OR.  You can make a larger incision to have a better contour but then you may as well just do it in the OR so you can remove the fat pads, etc.. 

You can be sure that you have a good grip on the levator (you can't see it) when the suture is dragged superiorly when the patient is asked to look up.

A patient with a perforating injury forty years ago and an updrawn and phimotic pupil with posterior synechiae.  He was nine years old when it occurred and he was game to try and repair it.  We planned to break the synechiae with Kuglen hooks and Healon in the OR and then enlarge and move the pupil later via laser iridoplasty.  Here he is pre-operatively:

Anterior capsule in liquified uveitic cataract   
I had a follow-up today of a patient with idiopathic bilateral panuveitis who had a white liquified cataract.  Here she is pre-operatively.

I was unable to get the anterior capsule to bend over itself to begin the capsulorrhexis, so I just aspirated the cataract through a small linear incision in the anterior capsule.  I extended the tear to 12 and 6 o'clock and oriented the IOL so that the haptics were oriented horizontally and "pushed" the anterior leaflets of the anterior capsule toward the limbus.

Here she is on POD #1.  Note how the anterior capsular leaflets are almost appositional. Over the next week she had a flare-up including a dense vitritis and papillitis.  This all resolved with oral steroids and a sub-Tenon's injection.   You can see the inflammed vessels on her iris.

Here she is today; the leaflets spread away nicely, probably due to tension from the IOL haptics.

Stem cell transplant   
A patient with severe eczema and chronic corneal irritation had two prior transplants OD and one OS.  Presented two years ago with severe vascularization with opacification OU and he had poor healing and chronic epithelial defects after the first grafts.  The left eye also had a perforation.  Hand motions/light perceptions pre-op.

Here's his pre-op photo.  I gave him a limbal stem cell allograft. Dr. Tseng's lab in Miami did the limbal impression cytology.

Here he is 6 months after the allograft, the grafts are at 3 and 9 o'clock.  Note the smooth and avascular corneal epithelium.  I placed the grafts in the interpalpabral fissure for cosmesis.He was lost to follow-up immediately after the surgery and did not get any immunosuppressants.  The graft survived well.

Then the new corneal graft. 

The photo is out-of focus but you can see the cornea is clear centrally. The patient was lost to follow-up (again) for six months after the PKP and there is some haze in the graft from 3 to 6 o'clock but he is happy with his vision.  The epithelium has survived two years without immunosuppressives.  Best vision is (I think) 20/80. 

He has a similar presentation OS and I gave him a stem cell transplant in that eye five months ago.  Here's the post-op photo OS.  We'll go for a triple procedure soon.  This one will be more challenging as there is a white liquid cataract and a very shallow chamber with anterior synechiae to the peripheral cornea from his prior perforation.

That's keratinized conjunctiva temporally.

A case from this morning.   

Did a triple-procedure this morning for a long-term challenging case.  It began with a severe contact-lens related corneal ulcer.  Corneal scraping didn't grow anything.

Here's how it healed over the next few months:

Eventually it went for penetrating keratoplasty, with a good result and 20/30 uncorrected vision.

Unfortunately, the patient then was shot in the right eye with a pellet from a pellet-gun and there was almost circumferential wound dehiscence.  I took him to the OR for exploration and to re-suture his graft.   Here he is, months later,  after removing most of those sutures.

The pellet is still lodged in his inferior orbit.  The oculoplastics specialist didn't want to remove it.  So he got another graft after the inflammation cleared. 

Then this cornea rejected a few months later and he developed a dense traumatic cataract.   He wasn't able to go through surgery for personal reasons for a year and today I replaced the graft, severed the synechiae, and removed the cataract.  I also covered the cornea with amnion as he might have some epithelial-healing issues following his conjunctival re-arrangement during his open-globe exploration.

inflammatory ulcer   
A small contact-lens associated corneal ulcer, but there was a lot of inflammation including fibrin in the a/c and some posterior synechiae. Turned-out  pretty well.

Tortuous vessels   
No complaints or other findings in this patient.  Congenital tortuous vessels?

Diabetic case   
An unfortunate patient who presented for her first diabetic eye exam.  The angiogram tells the story pretty well.

Posting old cases   
Here's a retinopexy from a few weeks ago for a small horseshoe tear.  It's not really interesting but it's a good photo for such a peripheral lesion.

First Post   
I updated the site to Jeremy Wadsworth's template version 2.8 and lost the last month of blog entries, so I'll upload a few of the cases that were up on the old site.  I'm having some problems with the masterpages but all the programs are still working.
