IVT

IVT is an acronym used in several different fields, and its meaning depends on the context. The term is most commonly associated with mathematics, computing, and ophthalmology, but it can appear in other disciplines as well.

In mathematics, IVT stands for the Intermediate Value Theorem. This theorem states that if a function is continuous on a closed interval [a, b] and takes on values on opposite sides of a given number, then there exists at least one c in (a, b) such that the function equals that number at c. The IVT is a foundational result in real analysis and is often used to prove the existence of roots for equations and to justify sign-change arguments.

In computing, IVT refers to the Interrupt Vector Table. This is a data structure used by some computer architectures to hold addresses of interrupt service routines. On older systems and some embedded architectures, the IVT provides a fixed map from interrupt requests to the code that handles them. Modern systems may replace or supplement the IVT with more flexible mechanisms, but the concept remains important for understanding interrupt handling and system design.

In ophthalmology, IVT stands for intravitreal injection. This procedure delivers medication directly into the vitreous humor of the eye and is used to treat conditions such as neovascular age-related macular degeneration, diabetic retinopathy, and retinal vein occlusion. Intravitreal injections require sterile technique and carry risks including infection, elevated intraocular pressure, and endophthalmitis, though many patients benefit from targeted drug delivery.

Context is essential for disambiguation, as IVT can refer to other specialized terms in different disciplines.
