Exophthalmometry

**Exophthalmometry** is a method for determining the degree of protrusion of the eyeball from the orbit by measuring the distance from the outer wall of the orbit to the most distant point of the cornea. This method allows you to estimate the size of the orbits, as well as the volume of soft tissue in the orbit. It is used in ophthalmology for the diagnosis of oculomotor disorders, orbital development anomalies, inflammatory processes and other pathologies.

The formula for calculating the force of exophthalmometry (Ex) is: Ex = S/C (S is the distance between the outer points of the posterior pole of the eye and the outer wall of the orbit at the exit point of the optic nerve, C is the distance between the outer point in the region of the vitreous plate and the outer edge

Exophthalmometry is a research method that allows you to determine the degree of convexity of the eyeball. This is an important parameter, since its change can be a sign of various eye diseases. The technique of exophthalmometry is simple and does not require special training. The measurement results are important for diagnosing various eye pathologies. Extraocular exophthalmography is especially relevant for children, when presbyopia develops - a type of ametropia associated with a lack of refractive power of the ocular media. In addition, exophthalmometric diagnosis is based solely on visual observation, which makes it absolutely safe and can be performed in young children without the use of pharmacological drugs and functional eye strain.
