Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forwa…

Loss or disturbance of limbal STEM CELL function in the CORNEAL LIMBUS resulting in inability to self-renew CORNEAL EPITHELIUM and conjunctivalized c…

A form of glaucoma in which chronic optic nerve damage and loss of vision normally attributable to buildup of intraocular pressure occurs despite pre…

The label is process-shaped, but the organ-specific concept may also function as a disorder; manual semantic review is required.

Fluid accumulation in the outer layer of the MACULA LUTEA that results from intraocular or systemic insults. It may develop in a diffuse pattern wher…

A chronic dysfunction of MEIBOMIAN GLANDS characterized by altered tear film stability and function due to a decrease or alteration in lipid quality/…

An inflammation of MEIBOMIAN GLANDS.

Congenital or developmental anomaly in which the eyeballs are abnormally small.

Dilation of pupils to greater than 6 mm combined with failure of the pupils to constrict when stimulated with light. This condition may occur due to …

A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodatio…

Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.

Failure or imperfection of vision at night or in dim light, with good vision only on bright days. (Dorland, 27th ed)

A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.

Abnormally low intraocular pressure often related to chronic inflammation (uveitis).

Granulomatous uveitis which follows in one eye after a penetrating injury to the other eye; the secondarily affected eye is called the sympathizing e…
