Monofixation syndrome (MFS) (also: microtropia or microstrabismus) is an eye condition defined by less-than-perfect binocular vision. [1] It is defined by a small angle deviation with suppression of the deviated eye and the presence of binocular peripheral fusion. [2]
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Deprivation Amblyopia: This occurs when something obstructs light from entering the eye, preventing proper vision development. A congenital cataract is an example of such a condition. Strabismic Amblyopia: The most common form, this type arises when the eyes are not properly aligned, leading to double vision. To avoid confusion, the brain ...
In a study conducted in 2011 on various Asian populations, variants in the PDGFRA gene on chromosome 4q12 were identified to be associated with corneal astigmatism. [10] A follow-up study in 2013 on the European population, however, found no variant significantly associated with corneal astigmatism at the genome-wide level (single-nucleotide ...

One important variety of bilateral scotoma may occur when a pituitary tumour begins to compress the optic chiasm (as distinct from a single optic nerve) and produces a bitemporal paracentral scotoma, and later, when the tumor enlarges, the scotomas extend out to the periphery to cause the characteristic bitemporal hemianopsia.
If the tumor is bilateral, it is almost always seen in a VHL patient. The tumor destroys the mastoid air spaces and extends into the middle ear and/or posterior cranial fossa. [1] [3] A high power image of an endolymphatic sac tumor showing clear cytoplasm in cuboidal cells lined up along papillae.
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [33] Because young children typically do not complain of blurry vision, the American Academy of Pediatrics recommends that children have yearly vision screening starting at three years old so that unknown refractive errors or other ophthalmic ...
