Risk Factors for the Development of Fellow Eye Horseshoe Retinal Tears Following Horseshoe Retinal Tear in the Presenting Eye.

Background: This study investigated factors associated with fellow eye horseshoe retinal tear (HST) development in consecutive patients with a presenting eye HST.
Materials and Methods: Medical records were reviewed for patients with initial HSTs between 2015 and 2017 and 24 factors were analyzed. Logistic regression was used to assess factors associated with fellow eye HST development.
Results: In total, 242 patients with an HST were identified with mean follow-up of 68.3 months. Four associations with fellow eye HST development were identified: (1) presence of fellow eye lattice degeneration, (2) subsequent presenting eye HSTs, (3) fellow eye vitreous hemorrhage at presenting eye HST occurrence, (4) OCT-determined stage 3 fellow eye posterior vitreous detachment at presenting eye HST occurrence.
Conclusion: Four clinical findings associated with fellow eye HST development following presenting eye HST were identified. These factors may be important considerations during management patients with HST. [ Ophthalmic Surg Lasers Imaging Retina 2023;54:338-345.] .
