Aims: Age-related macular degeneration (AMD) is the most prevalent cause of irreversible blindness and debilitating in old stages, in developed and developing countries that engage the central part of the retina or macula. The aim of this study was to evaluate the relationship of the rs4151667 position of the complement factor B gene polymorphism with AMD (dry type with geographic atrophy phenotype) in the North East of Iran population.

­Materials & Methods:­ In this descriptive cross-sectional study in 2015-2016, 44 AMD patients (dry type with geographic atrophy phenotype) were randomly selected from Gonabad City, Iran, health centers as the patient group. 50 healthy individuals from the same society that have no relative relations with each other or the patients, but were adapted by age and sex to the patient group, were selected as the control group. The ­­polymorphism of rs4151667 (c.26T>A)­ position of the complement factor B gene was determined for all samples by Restriction Fragment Length Polymorphism (RFLP). Data was analyzed the Chi-square test in 2x2.Contingency software.

Findings: The frequency of TT genotype in AMD patients (95.5%) was significantly (p=0.048) more than the control group (88.0%), but the frequency of AT genotype in AMD patients (4.5%) was significantly (p=0.025) less than the control group (12.0%).

Conclusion: The polymorphism of rs4151667 (c.26T>A) position of complement factor B is effective on the development of AMD in North East of Iran population.
