Comparative Analysis of Treatment Approaches for Anisometropic Amblyopia: Exploring Traditional Method, Dichoptic Therapy and Implantation of Collamer Lens

Abstract

Introduction: Anisometropic Amblyopia is a prevalent Amblyopia with a numerous refractive difference between both eyes in patients. It is the major cause of binocular single vision anomalies, which can also lead to blindness if left untreated. According to traditional theory, anisometropic amblyopia is reversible with proper treatment only if the patient is under 12 years of age. However, recent findings suggest that amblyopia can also be reversed in adult patients if proper treatment is provided including surgical interventions.

Aim: This review article evaluates the effectiveness of the traditional therapies including optical correction, the dichoptic therapy, and the impact of Implantable Collamer Lens surgery as treatment options for anisometropic amblyopic patients of all age groups.

Methods: Articles on the treatment of anisometropic amblyopia with traditional therapies, dichoptic therapy, and implantable collamer lenses were searched in the Google Scholar, Scispace, and Scopus databases. These articles discuss the efficacy and accuracy of aforementioned treatment approaches.

Results: Evidences suggest that traditional therapy for amblyopia including optical correction, dichoptic therapy, and implantation of collamer lens provides a significant improvement and efficacious as management. Collamer Lens implantation is more effective compared to other refractive surgeries of any age. In some cases, it has been observed that the improvement is better when all these treatment options are used in combination.

Conclusion: In anisometropic amblyopia, both types of treatment options surgical and non-surgical are important. Implantable Collamer Lens serves as a viable treatment option for patients with higher degrees of anisometropia and not responding to other traditional therapies.
