Can Chronic Visual Discomfort Measures Accurately Predict Acute Symptoms?

Can Chronic Visual Discomfort Measures Accurately Predict Acute Symptoms? 

 This study noted that....These data suggest that the Conlon and Convergence Insufficiency Symptom Survey (CISS) surveys are good predictors of acute symptoms induced during a binocular examination and validate the use of chronic symptom surveys as screening tools for symptomatic binocular dysfunction....

A prospective study of different test targets for the near point of convergence

A prospective study of different test targets for the near point of convergence

Abstract
Purpose: To determine whether different test targets including an accommodative target (AT), a
transilluminator (TR), and a transilluminator with a red lens (RL), affect the near point of convergence
(NPC) value; and to determine which test target is most sensitive to identify convergence
insufficiency (CI) in young adults.

Methods: Subjects were 36 optometry students from the Illinois College of Optometry, including 18
subjects with normal binocular vision (control group) and 18 subjects with CI. None of the subjects
had accommodative insufficiency. The NPC break and recovery were measured by three methods:
AT, TR, and RL. Each test method was administered by a different examiner and the test sequence
was randomized.

Results: The mean NPC break values for AT, TR, and RL in the control group were 4.31, 3.76, and
4.08 cm respectively, compared to 10.05, 11.37 and 13.04 cm in the CI group. The mean recovery
values were 6.23, 5.56, and 5.95 cm for AT, TR, and RL respectively in the control group, vs 12.21,
14.37, 16.40 cm in the CI group. Significant differences in NPC break and recovery values were
detected in the CI group between RL and AT, but not between AT and TR, or TR and RL. There was
no significant difference in NPC values using the three targets in the control group. For an NPC cut
point of 6 cm (break) and 9 cm (recovery), RL had higher sensitivity (100%) and specificity (88.9%)
as well as lower false positive (10%) and false negative (0%) values compared to AT.

Conclusion: NPC with RL is a more sensitive method to identify abnormal findings and assist in diagnosing CI compared to using AT or TR. We recommend that NPC with RL be routinely used to evaluate patients suspected of having CI.

Comments: Since convergence insufficiency is frequently encountered in all age groups and can significantly detract from ones quality of life, the NPC test with a red lens as noted above should be a routine, standard part of any comprehensive eye and vision examination.

Deadline Approaching:International Conference of Behavioral Optometry Call for Papers/Posters

CALL FOR PAPERS

International Conference of Behavioral Optometry
September 11-14, 2014 Birmingham, UK

The International Conference of Behavioral Optometry is soliciting abstracts for papers and posters to be presented at the 2014 Meeting. Any person wishing to make a presentation is invited to submit a proposal as outlined below.

 Proposals may include research results, case studies, or new and innovative diagnostic procedures or treatment techniques. Abstracts will be accepted as oral or poster presentations. Presenting authors must be registered participants and attend the meeting.

Submission of an abstract acknowledges your acceptance for the abstract to be published in all printed material of the Meeting Abstracts will be published in Optometry & Visual Performance.

Abstracts must be original and must not have been published or presented at any other meeting prior to the ICBO 2014 Meeting.
Abstracts must be submitted in English
All studies must have been approved by institutional committees on ethics of experimental and human investigations

Abstract title - limited to 20 words
Abstract text – limited to 350 words, including acknowledgements.

Abstracts of research projects should clearly state:
Background and aims
Methods
Results
Conclusions

Abstracts of case reports should clearly state:
patient’s symptoms, findings, diagnosis, treatments outcomes

Abstracts of diagnostic or therapeutic techniques should clearly describe:
the procedure, its applications, its unique or innovative characteristics.

Use only standard abbreviations; place special or unusual abbreviations in parentheses after the full word appears the first time. Use generic names of drugs. Express numbers as numerals.

Conflicts of Interest / Disclosure: Work submitted for presentation must include an acknowledgement of funding sources of commercial nature and/or consulting or holding of significant equity in a company that could be affected by the results of the study

THEME OF THE MEETING: Vision is the brain’s way of touching.
To maximize consideration for inclusion in the meeting you may choose to align your topic to the above stated theme or the tenets of behavioral vision care which follow:
The primary purpose of the visual process is the direction of action.
Most movement is visually guided.
Most visual problems are problems of omission, not commission.

SELECTION CRITERIA Each abstract will be reviewed for the following elements: (1) scientific and clinical quality; (2) broad appeal to the interests of the meeting attendees; (3) multidisciplinary nature; (4) timeliness of the topic.

Each complete submission received by December 1, 2013 will be independently peer-reviewed and rated on a blind evaluation basis.

First authors will be notified of acceptance or rejection by March 1, 2014.

The Natural History of the Oculo-Visual Anomalies Associated with Traumatic Brain Injury (TBI): A Case Report

Maino D, Schlange D. The Natural History of the Oculo-Visual Anomalies Associated
with Traumatic Brain Injury (TBI): A Case Report

This poster was presented at the 2013 College of Optometrist in Vision Development annual meeting in Orland, Fl.

Summary

As with our patient, research has noted that those adults with intellectual disability and a psychiatric illness tend to offer few complaints when taking a case history even though they are often on numerous medications and exhibit frequent visual and systemic anomalies. ......The longitudinal findings seen here suggest that those with TBI may demonstrate variable findings over their lifetimes and require close monitoring of these changes so that appropriate and timely intervention can be provided. It also appears that surgery for strabismus may be of limited intermediate and long term value. Optometric vision therapy appears to have moderate success at least initially. Vision therapy may need to be re-instituted with this now adult patient to help her regain the 2nd degree fusion and stereopsis that TB demonstrated after the initial therapy program some years earlier.....
