Sick and visually impaired?

Recently I caught sight of Asa, and the way the light was falling on him made him look to me, for the first time, like the sort of children we sometimes see in hospital waiting rooms – Completely bald from chemotherapy.  And unwell.

This struck me, because for the most part, Asa doesn’t seem sick to us these days.  He’s so lively, so playful and happy that we often forget about his illness.

Of course, his hair has almost disappeared.  He sometimes looks pale. And he still sometimes needs an NG tube to get his medicine in.  But that’s about where the resemblance to a sick child ends.

Sometimes friends ask how Asa is doing, saying “We heard he’s very sick.”  

It can produce an odd look from us, because it’s both true and untrue.

The end of chemo

During the 5th cycle of chemo, Asa was on a lower dosage (50% Vincristine), and the side effects were milder.  His appetite declined early on, but soon he was eating more or less normally again, and his energy levels were high.  He had none of the discomfort we’d seen during the 1st and 4th cycles. He needed a transfusion of platelets in the second week, but his haemoglobin level remained in the normal range throughout.

As the cycles of chemo have progressed, we’ve gotten more relaxed.  Whereas a couple of months ago we were keeping him confined to a few designated safe areas in the house, these days he roams widely (most of the time, on two feet), and he’s made the place his own.

Tomorrow, if all goes well, Asa will receive his last dose of chemo. 

It will take about 3 weeks to work its way out of his system.  After that, we hope we may be able to relax even more.

The latest on Asa’s eyes

The latest news we have on the cancer, from an examination 3 weeks ago, is this:

The large tumours in both eyes are inactive, and in the process of becoming calcified. 

But there are 50 to 100 seeds (small, beginnings of tumours) in the retinas of each eye; and in the left eye there are 2 vitreous seeds – seeds outside the retina.

Whereas before chemo both retinas were detached, the retina of the right eye has now become attached again.

The prospects of the retina re-attaching in the left eye are lower – As a doctor told us, if the retina hasn’t attached by the 4th cycle of chemo, it’s unlikely to do so afterwards. 

This is important for a couple of reasons.  For one, a detached retina impairs vision.  For another, a class of therapies including laser and cryo aren’t possible if the retina’s detached (they can detach it even further).

Because the retina in the right eye has re-attached, laser therapy could be performed on the subretinal seeds in the right eye at Asa’s last session.  But nothing was done to the left eye.

So what are the options for the left eye? 

If either the seeds or the large tumours in the left eye become active again, then the first recourse might be intra-arterial chemotherapy (intra-arterial melphalan, or IAM), delivered directly to the eyeball rather than to the whole body.

And although the doctors haven’t mentioned it recently, there remains a possibility that if the therapies don’t work, the eye might need to be removed.

We hope and pray that won’t be necessary. 

Implications for vision

What does all this mean for Asa’s vision at present? 

With the retina detached in the left eye, the doctors infer that Asa can only see “light and dark” out of that eye.  And because of the size and position of the tumours in the right eye, they assume he has only limited vision there. 

But there’s a weird disconnect between the doctors’ judgments, based on examining Asa’s eyes under anaesthetic, and our observations of his behaviour from day to day.

First of all, he gets around, makes eye contact, snatches things from us, and generally behaves just like any other child.  There’s no obvious visual impairment at all.

Second, when Selam breastfeeds him, Asa often has one eye at least partially covered, as he lies sideways on her lap.  In this position, she’s able to test his vision in each eye by proffering things (her necklace, a mobile phone, and so on) and seeing whether he reaches for them. 

Selam’s impression, based on many such tests, is that Asa sees better with the left eye than his right.  He’s more likely to reach for stuff when his right eye is covered than when his left eye is. 

Which is precisely the opposite of what we’d expect from what the doctors tell us.

One interpretation of this is that the “light and dark” he gets from the left eye is better even than the partial vision he gets through the right eye (where the tumours are more centrally located). 

Since he doesn’t cooperate when people try to patch one eye (he protests and tries to rip the patch off), it’s difficult to test him formally.

But he’s clearly using what vision he has to the max.

Next month, after the last cycle of chemo is finished, we’ll have a follow-up vision test at the Royal London Hospital.  Perhaps then we’ll get a better sense of how well he’s seeing, with each eye. 

For the moment, it remains a daily wonder to see him roaming and playing, and defying anyone to call him sick or visually impaired.

  2. Hi Jed and Selam-- so wonderful to read this latest news. I'm currently in Addis until mid July-- please let me know if there is anything you might want me to bring to Atlanta from here. And, any chance you'll be traveling to Ethiopia this summer?
    Thinking of you all very fondly!

Afterlife

Spring. Bulbs and buds burst into flower. Things come back to life.
Ayya's namesake Anne was born in Spring, in Nashville, Tennessee, on March 25th (also known as Lady Day, or the Annunciation), the day when people in Medieval Europe thought the world began.


What threads connect Anne to Ayya? What affinities, beyond a name, and a fraction of shared genetic material?
As a young woman, Anne lived in Africa for five years. She had just married a Frenchman, Jean-Paul, and accompanied him to Cameroon, where he was to work as a teacher in lieu of military service. She was a new mother at the time (she carried my cousin Miriam with her), and it was there that she gave birth to her second child, Eric.
One of my favourite works of anthropology is a study of infancy in West Africa. Among the Beng of Cote d’Ivoire, children are understood to come from the Afterlife. In their way of thinking, people’s spirits enter a sort of limbo when they die. When babies are born, they gain passage back into l…

Cataract / VI

At about 4 o’clock this afternoon, Asa came around after being under anaesthetic for a cataract operation. It was the first time he’d had surgery – indeed, anything but routine eye exams – for more than a year.
Selam and I felt more anxious than we’d expected to be about this operation. It brought back memories of difficult times. Times – there had been dozens of them – when we waited, with a mixture of fear and hope, for news of how the procedure had gone. There had been a few times when we’d felt we we were close to losing him – like that time when he was on second-line chemo, and I was in Congo, and Selam told me over the phone that his Hickman line was infected. Or that time, during the third course of chemotherapy, when he went into anaphylactic shock.
Compared to those occasions, this cataract operation was low-risk. And, thank goodness, it went smoothly.
As Asa gradually regained consciousness, he put his fingers to the plastic shield taped over his right eye to protect it. Sela…

Blind for a day

My mum likes to say that we learn about our bodies the way we learn about cars -- each time something goes wrong, you get acquainted with a new branch of mechanics.

As various treatments have been tried out on Asa, we've learned more and more about cancer and the eye.

The graph below summarises the treatments Asa's received these past 18 months.



Situations where retinoblastoma fails to respond to both primary and secondarychemo are rare, and even at one of the world's specialist treatment centres, a doctor might see such a case only once every few years.

 Support research on eye cancer here.
Right now we're in a place, therefore, where epidemiology and large trials have ceased to help much, and clinical judgment becomes very important.

As Dr Jenkinson -- the oncologist we met with in Birmingham -- said, "We're beyond the situation where there's a firm evidence base."

What's required then is very close attention to the details of the disease as it'…
