The misaligned eye will deviate inwards or outwards. The process is repeated on both eyes and then with the patient focusing on a distant object. The cover test is used to determine both the type of ocular deviation and measure the amount of deviation. The two primary types of ocular deviations are the tropia and the phoria.
Uveal melanoma is a type of eye cancer in the uvea of the eye. It is traditionally classed as originating in the iris, choroid, and ciliary body, but can also be divided into class I (low metastatic risk) and class II (high metastatic risk). Symptoms include blurred vision, loss of vision or photopsia, but there may be no symptoms.
Cancer associated retinopathy. Cancer Associated Retinopathy (CAR) also known as Carcinoma Associated Retinopathy is an immune-mediated disease affecting the retina of the eye.

When series creators David Benioff, D.B. Weiss and Alexander Woo first crafted the moment Jin Cheng (Jess Hong) and Thomas Wade (Liam Cunningham) enter the game in “3 Body Problem,” they made ...

The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance.
