That time of the year again

Last Christmas, I was thrilled to post that my son's Coats Disease had stabilized after two rounds of cryo and laser. It was my best Christmas gift ever.
Now it's that time of the year again. And just like last year, the eye exam has been delayed for one reason or another. He's actually not past his due date but I usually start early because I work myself up into such a frenzy that I want to know the results as soon as possible. He's had two more eye exams (one in March, the other in August) and the doctor says there's been no fresh leakage. The exudates (existing leakage) are still there, though. The doctor says they'll get absorbed over time, or he can use laser.
The kid also has glasses now - very, very low power and in both eyes. He also hasn't complained of any floaters or other discomfort throughout the year.
This time, we've kept missing the doctor (he was away for an emergency surgery the first time and the next week, I clean forgot - the stress is making me senile). We were all set for tomorrow, but it turns out the doctor's going to be in surgery again.
On Monday, the kid has his school's annual program. Tuesday's supposed to be a "bad day" for kids to be taken to a hospital; Wednesday the doctor's in surgery again; Thursday's Christmas, so the hospital OPD is closed; and Friday's surgery day again. Saturday we're leaving to visit my in-laws for a week. And then school re-opens again. And I am falling apart with the stress. It always builds up in the days running up the test.
A few days ago, a colleague mentioned my son's case to her eye doctor. He doesn't know my son's doctor but recommended someone else in the city. So that's another thing driving me crazy - do we stick by our doctor or get a third opinion (we've already had a second opinion - and it matched our doctor's).
Anyway, I'm sooo hoping the doctor will be able to spare some time to see my son tomorrow. Hopefully his assitant will be able to give me a clearer reply.
I honestly don't think I'll be able to go two weeks without knowing how my son is doing. The thing is, his condition has been stable since the last cryo in Oct 07 - which makes me wonder if all this is too good to be true.
I'm hoping and praying...
