When the Problem Wasn't the Eyelids

Ray came to me because he constantly held his chin up in order to see.

The assumption had been that the chin-up posture was caused by droopy eyelids. In fact, he had already undergone eyelid surgery elsewhere. But when I examined him, something much more important stood out: he could barely move his eyes upward.

The problem was not the eyelids.

Both inferior rectus muscles, especially the left, were extraordinarily tight and mechanically pulling the eyes downward. During surgery, I found some of the most severe restriction I have encountered.

In complex strabismus surgery, there is a principle often attributed to Marshall Parks and David Plager: relieve the restriction first.

Before surgery, I knew there was a possibility that once the restriction was removed, another alignment problem might become visible. In fact, one week after surgery, Ray developed a large outward drift of the eyes (exotropia).

This was not entirely unexpected.

The question was whether the exotropia represented an underlying neurologic or innervational problem, or whether the tight inferior rectus muscles had been masking the normal balance of the other eye muscles for years.

Either way, relieving the restriction was still the correct first step.

If the exotropia persisted, additional surgery could have been considered. That was Plan B. Other strategies were available as well. The important thing was to address the primary mechanical problem first and then allow the eyes time to reveal what remained.

As it turned out, the answer became clear on its own.

Within a month, the exotropia resolved completely without further treatment. Once the restriction was gone, the eyes re-established a much more normal balance. Upward eye movement improved dramatically, the eyes became straighter, and most importantly, Ray no longer needed to hold his chin up to see.

Complex strabismus surgery often involves uncertainty. Success comes from understanding which problem must be solved first, anticipating what may happen next, and having a thoughtful plan for every outcome.
