Fun with traumatic repair
Ok, so it's been a while since I (John) posted some cool ophthalmology cases. For those that don't like eye ball pictures, I promise these aren't too bad....
1. A 24-year-old male reported decreased
vision in the right eye for 2 years. After some questioning he admited that the eye had been struck by a soccer ball, and that is when the
decrease in vision began. His vision was found to be hand motions olny.
The pupil was irregular, and appeared to have a traumatic iris
coloboma. There was no afferent pupillary defect and a sonagraphy
(B-Scan) was done showing a normal appearing retina and optic nerve.
IOP was normal. *Disclaimer, this photo is not my actual patient but, you get the idea
I was very concerned about potential
zonular pathology in the area of iris defect, but agreed to attempt a
surgical correction. I spent more time than usual pre-operatively
explaining that the vision result of surgery may not be good.
At the start of surgery I was
pleasantly surprised to find the lens stable and no obvious zonular
loss. I was able to complete a linear capsulotomy ( was worried about
CCC causing troubles here and still worried about long term zonular
stability for in the bag placement of IOL).
For the lens implant I placed a 1 piece
PMMA lens with haptics in sulcus and optic beneath linear flaps of
capsule.
I then turned attention to the iris
coloboma. It had been a few years since I performed iris suturing,
but figured this was a great case to get some practice. I only had one
error, the first pass I attempted with the long CIF-4 needle was
completely wrong, and had to redo it. However, the second pass was
much better, and I tied it with a McCannell knot. Couldn't quite
remember the siepser slip knot. The result is shown below at 1 week.
The vision result was a pleasant surprise, 20/40 un-corrected,
resulting in happy patient and even happier doctor.
2. A 32-year-old man had been involved
in a motorcycle accident one day before coming to the clinic. The only
injury he suffered was to the left eye. Vision was perception of
light, no APD. He had a corneal laceration and traumatic cataract,
(This picture is actually from a different patient, but very similar
presentation)
I performed urgent surgical repair.
During surgery it became apparent that the posterior capsule had been
violated from the perforation. I performed a lensectomy, vitrectomy
and sutured the corneal wound. I left him aphakic. Fortunately, the
eye did well post repair, as shown.
With a +10.00 lens he was seeing 6/36
in our clinic. The problem was his other eye is a perfect 6/5 and the
imbalance prevented glasses correction. You eye people out there may
be wondering about contact lens correction, but frankly it doesn't
exist in Angola. So my options were leave him afakic (he declined
this), anterior chamber lens (surgeon was hesitant for this because
ascan showed a 22D lens would be best and I only have 19D ACIOL) or
iris sutured lens. All of these options have pluses and minuses. I
elected to place an iris sutured IOL. I think it was a good enough
option for him and plus I was really wanting a case to practice this
technique on. Surgery went well, only had a little trouble
positioning the lens with haptics behind iris with optic capture
anteriorly. I used a monarch injector to place a 3 piece MA60-AC
acrylic lens (which I now have with our phaco supplies).
Here is his appearance at one week.
Vision has improved to 20/60, which I am pleasantly surprised with,
given the cornea scar and astigmatism.
Please, for any anterior segment
surgeons who may be reading, send me your comments, tips or other
feedback.
