ASF Maddox Wing

The ASF Maddox Wing is a handheld diagnostic instrument specifically designed for use by ophthalmologists, orthoptists, and optometrists. It is utilized for the precise measurement of strabismus, encompassing both latent eye misalignments (heterophorias) and small manifest deviations (heterotropias) at near fixation distances. This portable device facilitates the quantification of horizontal, vertical, and torsional (cyclophoria) ocular deviations, providing critical data for assessing binocular vision stress and associated symptoms.

Constructed from durable plastic, the Maddox Wing operates manually, making it a practical tool for various clinical environments, including hospitals and clinics. Its design employs septa to dissociate binocular vision, ensuring that each eye perceives distinct targets—one eye views arrows, while the other observes numbered scales—thereby revealing the eye's true resting position during near focus. This method is essential for identifying subtle disruptions in eye alignment that may contribute to visual discomfort.

Key Features : 

Measures latent strabismus (heterophorias) and small manifest deviations (heterotropias) at near fixation distances.
Quantifies horizontal, vertical, and torsional (cyclophoria) eye muscle imbalances.
Aids in diagnosing conditions such as convergence insufficiency and accommodative disorders.
Provides data for guiding interventions like prism prescriptions or vision therapy.
Assists in identifying "hidden" vision issues that may affect reading stamina and cause symptoms like headaches or neck stiffness.
