ÖZETAmaç: Bilateral ambliyopi olan hastalarda farklı tiplerdeki refraktif kusurun görme keskinliği ve stereopsis üzerine olan etkilerinin belirlenmesi amaçlanmıştır. Bulgular: > 4 D hipermetropisi olan hastalarda başlangıç EDGK belirgin olarak düşük bulunmuştur (p=0,028) ancak gözlük tedavisi sonrası ölçülen sonuç EDGK değer-leri farkı istatistiksel olarak anlamlı bulunmadı (p=0.235). Astigmatizm değerlerine göre sınıflanan gruplarda (<2 D, 2-4 D, 4-6D astigmatizm) başlangıç EDGK değerleri farklı değilken sonuç EDKG ölçümleri 4-6D astigmatizm olanlarda ve 2-4 D astigmatizm olanlara göre anlamlı olarak düşük bulundu (p=0,001). Refraktif kusur derecesine göre karşılaştırıldığında yalnızca ilk EDGK değerleri 1. grupta 2. gruba göre anlamlı derecede düşük bulundu (p=0,015).Sonuç: Yüksek derecede hipermetropisi olan hastalarda ilk ölçülen EDGK değerleri düşük olsa da hastaların göz-lük tedavisine olan cevapları iyidir. Ancak yüksek derecede astigmatizm olanlarda bu cevap sınırlıdır. Results: The initial binocular BCVA levels were significantly lower in patients with > 4 D of hypermetropia (p=0.028), without correction after treatment (p=0.235). The initial binocular BCVA was not different between astigmatism groups, but final BCVA levels were significantly lower in 4-6D of astigmatism compared with 2-4 D of astigmatism (p=0.001). During comparison of composed refractive errors, only the initial binocular BCVA was significantly lower in group I compared to group II (p=0.015). The final binocular BCVA levels were not different between groups I and III (p>0.05). Conclusions:Although the initial BCVA is lower in patients with higher levels of hypermetropia, the response of patients to treatment with glasses is good. The response of patients with high levels of astigmatism seems to be limited. J Clin Exp Invest 2012; 3(4): 467-471

Parallels between use of constraint‐induced movement therapy to treat neurological motor disorders and amblyopia training

There are striking similarities between the visual defect of amblyopia and the motor deficit of the extremities produced by such types of damage to the central nervous system (CNS) as stroke and traumatic brain injury, both after and before maturity. Part of the motor deficit of the extremities following CNS injury can be attributed to a learning phenomenon termed "learned nonuse" or if present from birth, "developmental disregard." The same mechanism is hypothesized to be involved in the development of amblyopia. Treatments that are efficacious in the remediation of these defects, Constraint-Induced Movement therapy and amblyopia training, also share a number of strong similarities. In addition, plastic brain changes are produced by CI therapy and are hypothesized to occur during amblyopia training.

The effect of occlusion therapy on motion perception deficits in amblyopia

There is growing evidence for deficits in motion perception in amblyopia, but these are rarely assessed clinically. In this prospective study we examined the effect of occlusion therapy on motion-defined form perception and multiple-object tracking. Participants included children (3-10years old) with unilateral anisometropic and/or strabismic amblyopia who were currently undergoing occlusion therapy and age-matched control children with normal vision. At the start of the study, deficits in motion-defined form perception were present in at least one eye in 69% of the children with amblyopia. These deficits were still present at the end of the study in 55% of the amblyopia group. For multiple-object tracking, deficits were present initially in 64% and finally in 55% of the children with amblyopia, even after completion of occlusion therapy. Many of these deficits persisted in spite of an improvement in amblyopic eye visual acuity in response to occlusion therapy. The prevalence of motion perception deficits in amblyopia as well as their resistance to occlusion therapy, support the need for new approaches to amblyopia treatment.

The results of treatment of anisomyopic and anisohypermetropic amblyopia

Abstract: FTO is superior to PTO for the treatment of amblyopia. The greatest amount of improvement in visual acuity was seen in simple myopes and the least in simple hyperopes. Compliance is critical for successful treatment of amblyopia.
