Predicting potential acuities in amblyopes: predicting post-therapy acuity in amblyopes.

Purpose: Amblyopic patients, or their parents, often want to know the potential for success before committing to treatment. Recent reports have indicated that the pattern visual evoked potential (pVEP) can be used as a predictor of the success of amblyopia therapy. Unfortunately, these studies did not determine if acuity estimates from pVEPs could accurately predict the acuity post-treatment.

A reevaluation of the Developmental Eye Movement (DEM) test's repeatability.

Purpose: To investigate the repeatability of the Developmental Eye Movement (DEM) Test in a group of third grade elementary school students.

Methods: Thirty, third grade children who passed a modified clinical technique vision screening were given the DEM and then retested 2 weeks later.

Results: A clinically and statistically significant improvement in mean scores from test to retest was found on the vertical time, horizontal time, and ratio score.

Validity and reliability of the revised convergence insufficiency symptom survey in adults.

Purpose: To assess the validity and reliability of the revised Convergence Insufficiency Symptom Survey (CISS) in adults aged 19-30 years. The CISS was developed to be the primary outcome measure for studies evaluating various treatments for convergence insufficiency (CI).

Methods: CISS mean scores from adults with symptomatic CI and adults with normal binocular vision (NBV) were compared to assess the survey's validity.

Validity and reliability of the revised convergence insufficiency symptom survey in children aged 9 to 18 years.

Purpose: To assess the validity and reliability of the Convergence Insufficiency Symptom Survey (CISS) in children aged 9 to 18 years. The CISS is the primary outcome measure for a pilot study evaluating two different treatments for convergence insufficiency (CI).

Methods: Children with CI were given the CISS twice to assess reliability.

Association of symptoms and convergence and accommodative insufficiency in school-age children.

Background: The purpose of this article was to investigate the association between convergence insufficiency (CI) and accommodative insufficiency (AI) and symptoms in a group of school-aged children.

Methods: Children ages 8 to 15 years were recruited from two public and 2 private elementary schools in Southern California. The CI Symptom Survey (CISS) was administered to all children before a Modified Clinical Technique vision screening.

Reliability of binocular vision measurements used in the classification of convergence insufficiency.

Purpose: To evaluate the reliability of binocular vision measurements used in the classification of convergence insufficiency.

Methods: Two examiners tested 20 fifth and sixth graders in a school setting who passed a screening of visual acuity, refraction, and binocularity. The tests, conducted using a standard protocol, consisted of von Graefe near heterophoria (NH), phorometric positive fusional vergence (PFV), nearpoint of convergence (NPC), and monocular pushup accommodative amplitude (AA).
