Pierce Borish Test || Convergence Controlled Refraction

The Pierce Borish test is a clinical assessment used to evaluate binocular vision and ocular alignment. It is named after two prominent optometrists, Dr. William Pierce and Dr. Emilie Borish, who developed the test to help diagnose and manage binocular vision disorders.
The test involves a series of procedures that examine how the eyes work together to create a single, fused image. It assesses the coordination and alignment of the eyes, as well as the presence of any eye movement abnormalities or binocular vision disorders.
During the Pierce Borish test, the patient is typically seated at a distance from an eye chart or a target. The optometrist or eye care professional may utilize various tools and techniques to evaluate different aspects of binocular vision, including:
Ocular Alignment: The examiner checks for any misalignment of the eyes, such as strabismus (crossed or turned eyes) or tropias (manifest deviations).
Stereopsis: This assesses the ability to perceive depth and three-dimensional vision by using stereograms or polarized glasses.
Fusion: The patient is presented with images that may be slightly misaligned, and their ability to fuse the images into a single, clear perception is evaluated.
Eye Movements: The examiner observes the patient's eye movements, including pursuits (smooth tracking) and saccades (rapid jumps), to assess their coordination and accuracy.
Accommodation: The patient's ability to adjust focus and maintain clear vision at various distances is tested.
By performing the Pierce Borish test, eye care professionals can identify and diagnose binocular vision disorders such as convergence insufficiency, divergence excess, amblyopia (lazy eye), strabismus, and other related conditions. The results of the test guide the development of appropriate treatment plans, which may include vision therapy, prescription glasses or contact lenses, prisms, or other interventions tailored to address the specific binocular vision abnormalities detected.
Overall, the Pierce Borish test provides valuable insights into the functioning of the visual system, helping eye care professionals make informed decisions regarding the management and treatment of binocular vision disorders to optimize visual comfort and clarity for patients.

Sir ,A 26 male coming with the complaing of Blurring of vision in BE and headache in my clinic,his vision is 6/6 BE and NPA uniocular and binocular 24CM,NPC is 22 D
Then what can we give the advice for this problem?
