Near Point Of Convergece
- One of the most common clinical methods to quantify convergence ability is to determine the closest distance to which one can converge their eyes. This is called the near point of convergence (NPC) and is typically recorded in centimeters.
- Normal range:-6 to 10 cms
WHAT IS CONVERGENCE INSUFFICIENCY:-
DEFINATIONS:"This is a condition in which the muscles of the eye responsible for convergence (turning the eyes in) appear to be weak, at least relative to the muscles responsible for divergence (turning the eyes out). However, the patient's eyes remain straight in fields of gaze. This results in "strained" eyes and the affected individual complains of headache, eyestrain, blurred vision, or fatigue with continued efforts at near work. This condition most commonly occurs in teenagers and young adults, though it can occur up through middle age."

Many undiagnosed children and adults avoid reading and close work or use various strategies to combat symptoms (using a ruler or finger to read, taking frequent breaks, etc.). The typical patient who seeks diagnosis is a teenager or young adult, complaining of gradually worsening eyestrain, headache, and blurred vision after brief periods of reading, and, sometimes, double vision with near work.
Convergence Insufficiency can be diagnosed and treated at any age.
