Part-time occlusion therapy for anisometropic amblyopia detected in children eight years of age and older.

Lee YR, Lee JY - Korean J Ophthalmol (2006)

Bottom Line: The major component of the anisometropia was hyperopia in 51.7% of the subjects, and hyperopia plus astigmatism was found in 24.1%.The time taken to reach the posttreatment BCVA was shorter in subjects with a better pretreatment BCVA (p = 0.019), but it did not relate to the compliance (p = 0.366).The most common component of anisometropia detected after 8 years of age was hyperopia.

ABSTRACT

Purpose: To determine the outcome of part-time occlusion therapy in children with anisometropic amblyopia detected after they were 8 years of age.

Methods: We analyzed 29 eyes with anisometropic amblyopia in children 8 years of age and older. The mean age was 8.79 +/- 0.98 (range 8-12) years old. The subjects whose best-corrected visual acuity (BCVA) did not improve by two lines or better within 2 weeks of wearing glasses full-time were prescribed occlusion therapy for 6 hours a day outside of school hours, along with the instruction to wear glasses full-time. Subjects who complied with occlusion for more than 3 hours a day were considered to comply well.

Results: The major component of the anisometropia was hyperopia in 51.7% of the subjects, and hyperopia plus astigmatism was found in 24.1%. The mean pretreatment BCVA score was 0.51 0.23 (LogMAR). Compliance was 89.66%. The mean posttreatment BCVA was 0.03 +/- 0.01 (LogMAR), and the success rate, based on a posttreatment BCVA of 0.1 (LogMAR) and better, was 96.43%. It took an average of 4.79 +/- 3.35 months to reach the desired posttreatment BCVA. The mean posttreatment stereopsis was 79.78 +/- 37.61 seconds of arc. The recurrence rate was 8%. The visual improvement was related to the degree of compliance (p = 0.000). The time taken to reach the posttreatment BCVA was shorter in subjects with a better pretreatment BCVA (p = 0.019), but it did not relate to the compliance (p = 0.366).

Conclusions: The most common component of anisometropia detected after 8 years of age was hyperopia. The part-time occlusion therapy, which had been carried out after school hours, was successful in most cases.

Distribution of the daily occlusion hours. When subjects who had covered their strong eyes for more than 3 hours a day were considered to comply well, the compliance of part-time occlusion therapy was 88.9%.*: One subject disontinued the occlusion therapy before his corrected visual acuity reached the plateau.

Figure 1: Distribution of the daily occlusion hours. When subjects who had covered their strong eyes for more than 3 hours a day were considered to comply well, the compliance of part-time occlusion therapy was 88.9%.*: One subject disontinued the occlusion therapy before his corrected visual acuity reached the plateau.

Mentions: In two cases visual acuity improved by 1.0 diopter (LogMAR=0.0) through simply wearing glasses for one month (Table 3). The other 27 cases performed the occlusion therapy, and the compliance rate was 88.9% (n = 24/27) (Fig. 1). As previously mentioned, the subjects were composed of three groups, the first group of 17 cases (58.62%) underwent occlusion therapy for 6 hours a day, the second group of seven cases (24.14%) underwent 4 or 5 hours of treatment a day, and the third group of two cases (6.9%) underwent 3 hours or less of occlusion therapy daily. In one case (3.45%) the treatment was abandoned and the subject did not pursue further occlusion therapy (Table 3).
