斜视是爸爸妈妈非常关心的问题。斜视指的是两只眼睛不能同时注视同一方向。两只眼睛同时向倾斜的角度看不是斜视。
正常现象
间歇性的斜视（外斜视或者内斜视）：大约2/3的新生儿都会有这些现象，大部分到3个月会消失。
假斜视：由于婴儿的鼻梁扁平，鼻梁皮肤遮盖住鼻子附近的一部分眼白造成斗鸡眼的假象。这个不是真的斜视，随着孩子年龄的增长，鼻梁的发育，这种假象自然会消失。
病理性现象
婴儿性内斜视：这是一种比较明显的内斜视，在2-3个月开始发生。通常幅度比较大，很容易发现。出现这样的情况，尽早去看儿童眼科医生。
调节性内斜视：通常在2-3岁发生，多在孩子看近处的时候发作。这是由于远视度数高或者眼睛调节过度造成的。
间歇性外斜视：经常在2-3岁变得明显，大多数两只眼睛交替出现外斜视。发生的原因不明确。
斜视可能会影响双眼视觉和立体视觉发育，因此任何形式的斜视，都应该尽早去看医生。在少数情况下，突然发生的新的斜视还预示着控制眼睛转动神经的损伤，可能的原因有肿瘤，感染等等，因此以前一直都很正常，却新发现有斜视尤其要注意早看医生。

Just the first week in 2024 back in clinic, I started seeing several pink eye cases. Some of these have one thing in common, that the patient recently had covid or other viral illnesses.
Patient #1 had covid related pneumonia and recovered 4 weeks later, her red eyes onset just a few days after pneumonia diagnosis. With treatment of doxycycline respiratory symptoms almost resolved, but red and painful eyes persisted. There was even involvement of the cornea and the iris (keratitis and uveitis).
Patient #2 had covid with bad symptoms (upper respiratory, fever and fatigue), but no pneumonia. Red eyes onset after she almost recovered fully from covid. The conjunctivitis appeared viral, no involvement elsewhere in the eye.
Patient #3 had cold symptoms, but did not test positive for covid, and we don’t know what virus he had. After he almost recovered from the coughing symptoms, his eyes became red. Only conjunctivitis and no cornea involvement.
There were earlier reports in 2020 when covid first came out that pink eye, or conjunctivitis, could be the first symptom and sometimes the only symptom of covid. I have not read much that the eye symptoms come after acute covid symptom resolution. But apparently that could happen, as I saw a cluster of these just in 2 days. It is common to see viral conjunctivitis showing up at the same time or some days after the cold symptoms such as in patient #1, not too often when the cold symptoms completely resolve like in patients #2 and 3. Of course, patients could be having different interpretations about the resolution of the respiratory symptoms- it’s possible they are just getting much better and not completely over the cold.
Anyway, in the peak of all the viral infections in January and February, you may come down with red eyes when you have a cold, sometimes even after coming out of a cold. Sometimes it’s not just a pink eye, it can be infection or inflammation of the deeper structure of the eye, and it is best go see an eye doctor.
Leave a comment below, when you had a pink eye, was it stand alone, or before or after cold symptoms?
