The Eye That Came Back

The Eye That Came Back

▶ Listen · Miss Applewood
Cover the eye she never used, she can see. Cover the healthy one, she goes blind.

The kitten was named Comma because of the curl of black on her side, and she had spent the first weeks of her life with one eye taped shut.

Not cruelly. The vet, Dr. Okonkwo, explained it fast while she filled out paperwork. Comma had been found with an infection that swelled the right eye closed, and a previous clinic had bandaged it to let it heal. The bandage stayed on too long. Now the eye was fine. The infection was gone. The lid opened. The pupil shrank in light like it was supposed to.

"So she can see out of both eyes now," Soren said.

"The eye works," Dr. Okonkwo said, which was not the same thing, and she was already moving to the next cage.

Maya was watching the kitten, not the vet. Comma was batting at a feather Maya dragged across the floor. She tracked it perfectly, pounced, missed by a hair, tried again, caught it.

"She sees great," Maya said.

"Cover the left one," Soren said.

Maya looked at him.

"The good one. The one that was never bandaged. Cover it and use the feather again."

Maya cupped her palm gently over Comma's left eye, leaving the right one, the rescued one, open. Then she dragged the feather.

Comma did nothing. The feather went left. The feather went right. The kitten's head did not turn. She swatted once, randomly, at empty air a foot from the feather.

Maya moved her hand. Both eyes open. Comma snapped onto the feather instantly.

Left eye covered again. Blind.

Uncovered. Perfect.

"The right eye works," Maya said slowly. "The pupil moves. The light gets in."

"But she can't see out of it," Soren said.

They sat with that. A kitten with two working eyes, one of which she could not use.

Soren had his notebook out. He drew an eye, then a line going back from it, then a question mark. "The light hits the eye," he said, talking the way he did when he was building a thing in his head. "It goes to the brain. The eye is fine. So the part that's broken is—"

"Behind it," Maya said.

Dr. Okonkwo came back with a syringe of dewormer. Maya didn't wait for politeness.

"Her right eye is blind even though it works," she said. "Why?"

The vet stopped. She looked at the kitten, then at the two of them, and Maya watched her decide they were worth the long answer.

"You found that yourself?"

"We covered the good eye," Soren said. "She went blind on the other side."

Dr. Okonkwo crouched. "The brain has to learn to see. It isn't ready-made. When a kitten is born, the part of the brain that handles vision is still wiring itself, and it wires itself based on what comes in through the eyes. Both eyes send signals back, and they sort of compete for space in there. Whoever sends the most signal claims the most brain."

"And her right eye sent nothing," Maya said. "Because of the bandage."

"For weeks. During the exact window when the wiring was happening." Dr. Okonkwo touched the kitten's head, very lightly, between the ears. "So the left eye took it all. Almost every cell back there now answers only to the left eye. The right eye is shouting into a brain that already gave its space away."

Soren's pencil had stopped. "But the bandage is off now. She has the eye back. Can't the brain relearn?"

The vet was quiet for a second too long.

"No," she said. "The window closed. There's a period early on when the brain is soft, when it changes based on what it gets. After that period ends, the wiring sets. You can give Comma that eye for the rest of her life, perfect light, perfect lens, and the brain will never go back and make room for it. The time to learn that eye was the time it spent in the dark."

Maya felt something tilt under her, the way the floor of an elevator drops half an inch before you feel it move.

"So there are things you can only learn when you're little," she said. "And if you miss it, it's gone. Not hard. Gone."

"For vision, yes. For a few specific things, yes." Dr. Okonkwo capped the syringe. "Brains have doors that open and close. Some of them only open once."

She got called away then, leaving them on the floor with the kitten.

Soren was writing fast. "That means right now," he said, not looking up, "there are doors open in us. Things our brains are doing this exact week because we're eleven, that they'll stop being able to do."

"And we can't feel it," Maya said. "Comma doesn't know her right eye is dark. She thinks that's just how the world is. Empty on that side."

That was the part that got into her chest. Not that the door had closed for Comma. That Comma would never know there had been a door.

Maya picked up the feather again. She covered the left eye, the good one, and held the feather still right in front of the right eye, an inch away, where even a blurry brain should catch the motion.

She wiggled it.

Nothing.

But Comma turned her head, not toward the feather, toward Maya. Toward the warmth of her hand maybe, or her smell, or the sound of her breathing. The kitten pressed her cheek against Maya's covering palm and started to purr, eyes both open, one of them seeing the room and one of them seeing a darkness it had no word for.

"She found you anyway," Soren said quietly. "Just with the other senses. The brain gave that space to something else. It always gives the space to something."

Maya didn't answer. She was thinking about all the doors. The ones still open in her right now, this week, this year, swinging quietly on hinges she would never hear. She took her hand away from Comma's eye.

The kitten blinked both eyes at the bright room, then climbed into the dark warm cave of Maya's cupped hands and curled into a comma, purring, where the seeing did not matter.
