Random Thoughts from a Restless Mind

“A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die.” –Max Planck

So very much of what we encounter as we seek any kind of guiding truth is not science at all, but strongly held opinion forcefully presented. Think about it for a moment. Think about a few of the really big issues orbiting the intellectuosphere. Climate change. Health. Fitness. The search for the cure for cancer. Heck, the decision on what to have for lunch. So many opinions…so much money…so little true science.

Even more than that, scientific truth is continually bludgeoned by the one-two punch of politics and commerce. True science has always been held hostage by those who have vested interests in what constitutes the prevailing truth at any given time. How many promising avenues of inquiry have been blocked, and how much time has been lost because of the failure to pursue additional lines of inquiry that ran counter to “consensus”? One need only think of inflammation in vascular disease or alternatives to “fat in the diet is unhealthy”, both squelched along with the careers and reputations of their proponents while the single consensus theory was pursued. Why? Alternate theories or parallel theories would siphon the spoils from those who fed at the consensus trough.

It’s quite tempting to hold that this is all relatively new, that it is a function of our highly developed Western societies. Tempting, but ultimately false. Has there ever been a time in recorded history when a new scientific truth has upended orthodoxy and there has NOT been an attempt by the entrenched to not only stop an new line of inquiry but also destroy those inquiring? Think Galileo. From where I sit it seems as if a substantial majority of truly disruptive new scientific truth has arisen from the ranks of those who stood aside the prevailing winds and charted their own course.

What does this mean for each of us as we sit in our own little boats and sail along? The trade winds of consensus are strong, and it seems the weaker the science behind them the stronger they blow. It’s fine to allow these to fill your sails, of course, for the majority of them do in fact propel us along a true course. The best course, however, may lie in the breezes that cross the trade winds. Those tiny little gusts that represent the true essence of real science–skepticism accompanied by inquiry, followed by proof–will ultimately propel us to the proper destination despite the power of the commerce attached to the trade winds.

Every now and again the Newport to Bermuda race is won by a rebel who went off alone and discovered a new truth about sailing. We should be open to the possibility of a new scientific truth in all parts of our lives, lest we find ourselves far behind, capsized in its wake.

Or worse yet gone, as Planck suggests, long before we ever had a chance to benefit.

As I mentioned, I’m on call for our large semi-suburban hospital for the month of July. I was consulted for a patient who has monocular vision loss that is unexplainable, at least given the capabilities we have as ophthalmologists when we see patients at the bedside in the hospital. The consult brought back memories of Julys past as a resident on call.

Bellevue Hospital, and the Bellevue Hospital residents provide medical care for the New York City prisoners who are housed at Riker’s Island. This is actually quite an opportunity, especially for a child of suburbia like yours truly. It’s not as if I had never come across people in the criminal justice system prior to my Bellevue days, it’s just that I didn’t have such routine and regular contact.I don’t remember exactly, but there are at least three or four entire floors at Bellevue dedicated to the care of Riker’s Island inmates who have medical problems. One or two are for the criminally insane, and others who have some degree of mental illness. The remaining two floors house prisoners with problems as varied at coronary artery disease and pink eye. As disconcerting as it was for someone like me to enter a locked ward, the accommodations at Bellevue were at least a full order of magnitude nicer than those at Riker’s Island. This provided an interesting opportunity for Riker’s Island inmates to create a medical reason to leave The Rock, and created a very interesting learning opportunity for all of the residents  to discern real from not so real.

This  might have been the most fun part of my entire residency experience.

People who have something to gain from having an eye problem all seem to have the exact same complaint: “I can’t see.” Sometimes it’s “I can’t see out of my right (or left) eye,” and sometimes it’s simply “I can’t see.” The savvier the patient, the more subtle the symptom. The trick as the doctor on call is to simply demonstrate that their vision is substantially better than what they are describing. Oh yeah, it’s important to do so in such a way that you don’t make them too very angry; you don’t want to become a Bellevue Hospital “target” yourself!

Every resident develops a repertoire of tricks that he or she will use, a go–to list that tends to work for the majority of the malingering patients. To be truthful, especially when caring for children, sometimes the patient is actually convinced that he or she really CAN’T see. The kids are really pretty easy, though. I found, and frankly continue to find, that even with my limited attention span (often described as being slightly shorter than that of your average gnat) that I have more patience than almost any child under the age of 18. Most eye charts will start with a 20/10 line, and then move through 20/12, 20/15, and then several to many 20/20 lines. If you start at 20/10, by the time you get the 20/25 or 20/30 that line looks absolutely enormous! I think I’m batting about .997 in kids with 20/400 vision in the ER who “miraculously” and up with 20/25 vision in the exam room.

Folks who have something to gain from being diagnosed with visual loss weren’t always wards of the state or city. Occasionally there would be people who stood to gain from being diagnosed with profound visual loss for other, less existential reasons than wanting a ticket out of Riker’s Island. My favorite was a Hispanic woman who came with an entourage of family members, her complaint being complete and total loss of vision in both eyes from some vague and poorly defined trauma suffered at the hands of a landlord who was trying to evict the her from a rent–subsidized apartment. Her examination was totally unremarkable. Everything about her eyes was so  normal it was eerie. My suspicions were high because she just didn’t seem all that distraught over her new blindness, you know? There’s an instrument called an indirect ophthalmoscope which is used to examine the peripheral retina. The light we use can be cranked up to a level which is quite frankly rather painful. I explained to my patient through her translator that I was terribly sympathetic, and very concerned about how she would ever be able to survive if she was  evicted, what with her being totally blind and all. I just had this one last test to do, to look at her retina. With phasers set on stun I started to examine her eyes with the light cranked up. She started screaming in Spanish. What’s she saying? What’s she saying? Remember, now, this is a woman who has no light perception, everything in her world is black. Her son grabbed my arm and started yelling at me. “Turn that light off. It’s too bright. It’s hurting her eyes!” Yup, just another satisfied patient.

The prisoners really were the most fun, though. You had to be on your toes because some of them were actually quite dangerous. If the corrections officers were chatting amongst themselves in the waiting room you could be pretty sure that the patient in your exam chair was nonviolent. If, however, there was a corrections officer standing roughly 1/2 inch from each arm of the patient, well, that was one you had to worry about. But the prisoners got it, they got that this was a game. If they could beat me they got a stay at the Bellevue Hilton. On the other hand, if I got the best of them, it was back to Riker’s Island. The guys who complained of decreased vision in just one eye were actually not too difficult to fool. Again, all I had to do was prove that the vision and the supposedly “blind” I was normal. We quote discovered” all kinds of sight threatening needs for a new pair of glasses at two o’clock in the morning in the Bellevue consultation room.

The guys who complained of decreased or lost vision in both eyes were more challenging and therefore more fun. Can’t see anything at all? Piece of cake. All I have to do was prove that they had locked on to some image. There must be three dozen prisoners who complained of total loss of vision in both eyes who headed back to Riker’s Island one minute after entering my consultation room after they leaned over to pick up the $10 bill that I put on a footstool of the exam chair. Did you know that your pupils constrict when you focus on an image inside arm’s-length? You can imagine how handy that three-year-old Sports Illustrated bathing suit issue came in, and how many prisoners learned about accommodative pupillary construction after looking at THAT picture of Christie Brinkley.

There is one story out of all of my adventures with the Riker’s Island prisoners that stands apart. It was July, and I was doing my duty helping out the new first-year resident on one of his first nights on call. We got a call from the ER about this terrified patient who had lost vision in both of his eyes; he was defenseless. Dave, now a world famous pediatric ophthalmologist, was really unsure of how to proceed so I told him that we would do it together. We sat back and watched very carefully as the prisoner entered the room. He was totally on his own, not assisted in the least by the corrections officers. He managed to navigate around all of the little articles I had placed between the door and examination chair, not hitting a single one. He found the chair, turned just like you or I would, and sat down. His examination was perfect, naturally. After putting drops in his eyes to dilate his pupils this is what I said: “I can see that you are terribly frightened sir, and frankly I can’t blame you. I’m very concerned about your vision, and I’m going to do everything I possibly can to make sure that you are alright. I just put some drops into your eyes so that your pupils will dilate. Dr. Granet and I will then examine your retinas once the drops have worked. We are going to talk about what we’ve seen so far. Please go back into the hallway and take a seat in the blue chair, and we’ll come and get you in just a few minutes.” The prisoner left the room, once again navigating the “mine field” without incident.

Dave bowed his head, a little tiny twitch at the corner of his mouth as he shook his head. “There’s only one blue chair out there, isn’t there?” He smiled as he strolled over to the door. Sure enough, there was our patient, very calmly sitting in the single blue chair, surrounded by a dozen empty red ones!

We had to invite the corrections officers into the exam room when we explained our findings.
