To predict the retinal tear location using axial length and analyze relationship between axial length and retinal tear location in the rhegmatogenous retinal detachment.
A retrospective review was performed on 500 patients (500eyes) who were diagnosed with rhegmatogenous retinal detachment and underwent scleral buckling surgery from march 2009 to december 2011. We analyze the relationship between preoperatively measured axial length using IOL master and tear location from the limbus which was recorded in the operative record.
Analyzing the relationship between the retinal tear location and axial length, we excluded patients who were younger than 20-year-old, whose axial length were longer than 29mm or shorter than 22.5mm or who underwent reoperation for achieving the anatomical success. Fianlly total 386 eyes were included in this anyalsis. Axial length and retinal tear location has positive correlation. We made a formulation the relationship between axial length and retinal tear location using the multiple linear regression. The formulation was tear location from the limbus (mm) = 0.013 x age + 0.397 x axial length (mm) + 1.532 (p<0.001).
This is the first report to evaluate relationship between retinal tear location and axial length. Retinal tear location is associated with axial length and age. In cases of hardly visible retinal tear, using the new formulation, we can predict retinal tear location through the axial length and determine the surgical method.
