I have a 10 yo bilateral (meridional?) amblyopic patient. I'm debating whether this is a case of neglect on the part of her parents and could use some outside opinions.

The patient was first seen a little less than two years ago (by another intern). At the time, her BCVAs were 20/40 OD & OS. Being 8 yo at the time, she was referred to our pediatrics clinic to finalize her refraction and begin amblyopia treatment. Her parents did not take her to her appointment. I do not know to what degree the intern who saw her stressed the importance of the appointment, but chart notes do state the parent present was told the patient needed glasses.

Fast forward about two years and the patient is now in my chair. On the intake form, the patient's mother made a note that the patient has a mental deficit (can't remember her exact wording); more on that later. The patient's chief concern was difficulty reading; she reported having to hold materials closer to read. She reported distance vision was fine. POHx, PMHx, FOHx, and FMHx were all reported as unremarkable.

Unaided VAs were:
OD: 20/400 at distance, >20/200 at near; no improvement with pinhole
OS: >20/400 at distance, >20/200 at near; no improvement with pinhole

Entrance testing was unremarkable, though I was unable to perform confrontational fields.

Her refraction showed low to moderate hyperopia and WTR astigmatism of -5.00 OD and -7.50 OS. Ks match these findings. Her BCVAs were 20/200- OD and 20/400 OS. Ant seg health was unremarkable.

At this point, I left the room to confer with my attending before taking IOP and dilating the patient. When I returned, the mother and the patient's two siblings had left. The mother made no attempt to inform me that she was leaving. Later, I found out that she had gone to take her other two kids to school. She returned about an hour and a half later.

In the mean time, the patient became very uncooperative. I was able to instill 1% cyclopentolate and 2.5% phenylephrine, but neither I nor my attending could get her to cooperate enough to evaluate the post seg.

Once the mother returned 90 minutes later, I had the front desk schedule her for another exam in one week with the absolute condition that the mother must be present for the entire exam. We made the appointment for later in the morning so the mother could drop her other kids off at school before the exam.

Next week, the mother arrives with only one extra kid. After a quick dry refraction, I gave her 1% cyclopentolate and 2.5% phenylephrine. The mother then told me she was going to leave to take her other kid to school. I explained to her the exam would not continue until she returned. It only took her 30 minutes to return. Wet refraction roughly matched her dry refraction. I was able to examine the patient's post seg. Post seg was unremarkable and I was able to achieve a clear image of her retina.

After consulting with my attending, we prescribed her best dry refraction. We explained to her mother that her child could not see, that the patient would likely notice little difference when wearing her glasses even though the glasses were helping, and needed to be seen regularly to monitor the patient's progress. The mother was told that the patient needed to be seen one month after getting the glasses.

It's been two weeks since she picked up her glasses and the patient has no appointment on the books. Tomorrow, I plan to do my own followup and try to get the patient an appointment.

If you're still reading this, thank you!

While my case for neglect is in no way complete enough for me to make a judgement, here are my points of contention:

1. The parent disregarded instructions to care for her child's vision.
2. This led to her child's BCVAs dropping from 20/40 to 20/400.
3. The parent left the child in my care without informing me.
4. The parent appears to be disregarding present instructions to care for her child's vision.

My other concern goes back to the mother's report that the patient has a mental deficit. I had the privilege of spending 90 minutes working with just the patient. She is quick witted, choses her words carefully, and is very knowledgeable as to how to manipulate others. In my own opinion, she is at least of average intelligence and likely has potential beyond that. She just can't see. I am concerned that her parents are simply categorizing her as such because of her poor performance in school.

Does this look like a case where I should suspect neglect? If what I suspect is true, does that even qualify as neglect?

Once again, thank you for making it this far down my lengthy post.

let's talk about the diagnosis first.

amblyopia certainly seems reasonable, but do you have the Ks? they seem incredibly high.

does the patient possibly have bilateral keratoconus?
 
Sorry, I don't buy the diagnosis of amblyopia. Further testing is indicated.

The VA change is astounding especially since the first exam was at 8 years of age. The VAs also don't correspond to what would be expected in a refractive amblyope.

I question the intial VAs from the 8yo appt. I have seen several children with several Rxs that high. For some reason its also almost always children of Hispanic descent.

Meridional amblyopia can cause pretty severe visual acuity loss though I agree that something seems off here and there should not be that large of difference.

Were the last VAs crowded Snellen or isolated? The fist VAs?
 
Not for anything, I'm not at all an OD or a professional, but I am a (former) patient. I was in this situation, and its important to hear from others to let you know - this patient is not alone.

The parents are either ignorant (not knowing) or in denial (believing that nothing is wrong). My aunt and father, both MDs, told my mother that I was autistic, ******ed, and would probably need care for the rest of my life. The pediatricians even said that they saw nothing wrong with my vision.

The day I walked in to his office, my opthamologist diagnosed me immediately with Strabismus, to the point that I was put into surgery not 4 months after meeting him.

This is not neglect, so much as the parents/family being completely convinced on pre-conceived notions of autism, mental ******ation, or something that could not be linked to their actual negligence (or something thats almost become cool by society - everyone and their grandmother has autism nowadays).

Very possibly genetic, but not just Hispanics - I've had basic genetics laboratory and lecture, and I can pick this out. The first things to go are the eyes when there is inbreeding - we see this with enough Jews (my father and sister are perfect examples), northern Europeans in general, and many rural parts of Latin America, where the lineage branches out only so far, and the most distant partners you can find are about 3rd cousin, if you are lucky. The American media has in fact flocked to the mountains of El Salvador to find that 90% of the residents had dwarfism caused by something unrelated, but the point rests as inbreeding.
We see this loss in visual capabilities with dogs and cats as well from the pure-breeding - the eyes go first. I'm not entirely sure why, I'm sure there is a very simple explanation.


As for the patient's history - most don't test for strabismus, which is a very common cause of these problems, coupled with increasing amounts of ocular stimulants from the TV and computer. Its possibly too late to tell, if she can't even see more than a few inches in front of her. Why do I bring this up? The double vision, or complete inability to see the letters, could have led to skewed test results.

Well, thats not surprising - I can assimilate information as well, and noticed post-op that my other senses were heightened. What happens when one sense goes down? The other four compensate. Hearing, in my experience, was what went up the most, followed by smell and touch.





Back to your original question, the parent's actions are not criminal, it's easy for the guardian to state that they just did not know, or that they got conflicting messages based on what they read. Or, that they've never heard of this condition, they didn't believe it existed (my former PCP never heard of my cardiovascular condition, so he wouldn't accept the diagnosis by the specialist). You need to first follow up, call the family, and let them know "hey, I remember seeing your child, I thought I mentioned that you needed an appointment in one month, noticed that she's due for one soon, and wanted to follow up". Then, if the family doesn't show up, you call on your regional equivalent of health and human services, and have them deal with it.

Ks were:
OD: 42.75/48.00@084, no distortion
OS: 42.75/49.20@089, no distortion

Yes, she's of Hispanic descent. VAs were Snellen. She could not pick out isolated letters (though I did not try to isolate letters larger than ~20/100).

I agree with both of you that her VAs are not completely explained a diagnosis of amblyopia. Amblyopia was the only component of her VA loss we could explain at the time, even if it turns out to be a small component of it.

Two possible other components of her VA loss I need to investigate when (if) I see her again are:

- Streff Syndrome: I haven't been able to get a reliable visual field; I want to try a tangent screen with this patient to both keep her attention and to check for malingering.

- Exaggeration/Malingering: She may be exaggerating her symptoms. The last time she was seen, she did not receive treatment and may think she will receive treatment if she makes it appear worse than it is. I doubt this is a large component of her VA loss, since she reached a similar end point on all of her subjective refractions, which also matched my objective findings and those of the autorefractor. It also wouldn't explain her lack of improvement with refractive correction.
 
ChemWiz101 – Thanks for the view from the chair. I think part of this is ignorance or denial by the parents based on their pre-diagnosis of their daughter. I'm trying to figure out to what degree and at what point someone should step in and intercede.

On the Hispanic genetic note, IndianaOD was referring to the tendency of those of Hispanic descent to have high astigmatism.

Interesting side note: This patient started three consecutive clinic days where I needed the auxiliary cylinder lenses on every patient (every patient had astigmatism that exceeded the capabilities of the phoropter). Yes, I see a heavily Hispanic population.
 
I wouldn't be so quick to rule out an organic cause of visual acuity loss.
 
As for the patient's history - most don't test for strabismus, which is a very common cause of these problems, coupled with increasing amounts of ocular stimulants from the TV and computer.

Not sure what you are talking about here. An OD student would check for strabismus on absolutely every patient. Could you clarify this?

IMHO surgery is a second choice for strabismics. Optometric vision therapy is much more effective functionally in most cases.
