Introduction Aniseikonia is an underrecognized condition that can cause significant symptoms. Affected individuals are often told their vision is normal and that no problem exists. Proper assessment is important for the diagnosis of aniseikonia, and appropriate treatment can improve the lives of the individuals who suffer from symptoms daily. The purpose of this case series is to describe the assessment and management of 3 cases of optically and/or retinally induced aniseikonia and to increase awareness of this condition. Case Reports In all 3 cases, the Awaya New Aniseikonia Test was used to measure image size differences. Afocal magnification lenses were also used to verify the need for image size correction. For each patient, spectacle lenses with an eikonic lens design were prescribed to decrease perceived image size differences between the 2 eyes and improve patient symptoms. Case 1: A 73-year-old man after cataract surgery with trabectome resulting in a cyclodialysis cleft and hypotony maculopathy in the left eye. Case 2: A 71-year-old man after cataract surgery with a history of monovision LASIK. Case 3: A 62-year-old man with a history of retinal detachment and repair with scleral buckle in the left eye. Conclusion Individuals with aniseikonia can present with significant symptoms such as headache, double vision, visual discomfort, eye strain, and fatigue. Because the condition commonly goes unrecognized, it is potentially more prevalent than previously reported. Increased awareness of aniseikonia can help eyecare providers identify patients with this condition for appropriate assessment, treatment, and management.
