How Do You Spell MADDOX DOUBLE PRISM?

1. The Maddox double prism is an optical device used in ophthalmology and optometry to assess and diagnose ocular conditions. It consists of two cylindrical prisms placed base-to-base, perpendicular to each other. This design allows the prisms to split light entering the eye into two slightly offset paths, creating a deviation in the perceived position of objects.

   The Maddox double prism is primarily employed in the assessment of ocular misalignment, commonly known as heterophorias or strabismus. By placing the prisms in front of one eye, the device causes the image seen by that eye to be displaced. This displacement enables the tester to identify and quantify deviations in ocular alignment and measure the degree of eye misalignment.

   The Maddox double prism is also utilized in identifying and evaluating the presence of certain eye muscle weaknesses, known as phorias or tropias. These conditions can cause symptoms such as double vision or visual strain.

   Additionally, the Maddox double prism is used to determine the orientation of a patient's eyes when performing eye muscle surgeries. By observing the displacement of the light rays, ophthalmologists can accurately plan and execute procedures.

   Overall, the Maddox double prism is a valuable tool used by eye care professionals to evaluate and diagnose various ocular misalignments and muscle weaknesses, facilitating appropriate treatment and rehabilitation techniques.

2. Two prisms with their bases in close apposition, employed in testing for torsion of the eyeball.
