Convergence Insufficiency: Modified Dot Card VS Conventional Orthoptic Exercises

Abstract

Abstract

Aim: To compare conventional orthoptic exercises and modified dot cards in the management of primary convergence
insufficiency.

Study Design: Experimental hospital-based study.

Duration and Setting of the Study: The study was conducted at Tawam Hospital Uinted Arab Emarat (UAE) from March 2021 to April 2022.

Method: Patients diagnosed with primary convergence insufficiency were divided into two groups. One group was given conventional orthoptic exercises (conventional dot card) while the other group was given a modified dot card. All the patients were instructed to exercise 5 times a day, each time for 5 minutes and were reviewed after three weeks and a second review after two weeks. Consent was taken from every participant.

Results: A total of 27 patients were included in the study diagnosed with primary convergence insufficiency. The age limit of the patients was between 13-24 years, to rule out the non-compliance part of the study. Participants treated with conventional methods showed a 62% success, while those treated with modified dot card had success rate of 83%. Furthermore, patients who were having remote near point of convergence (NPC) and who showed no improvement at all with conventional exercise were given modified dot card for exercise. By switching to the modified card they showed a very good improvement in their symptoms and NPC.

Conclusion: The modified dot card is an effective test that can be used in patients with mild, moderate, and marked convergence insufficiency.
