Resorption Of Central Drusen Following Laser For Peripheral Tear

Abstract

Abstract: : Purpose:Resorption of central drusen following peripheral retinal tear laser to both eyes is reported. Methods:Laser repair to a peripheral retinal tear was performed to OS. OS had central drusen followed for 15 years that showed increasing confluence occupying 32% of the central 50° field. The fellow OD with scant central drusen (occupying 5% of the central 50°) had pigmented subretinal neovascularization (SRN). VA OD HM, OS 20/30. Results:Sixteen months postlaser OS resorption of 50% (32%-17%) of central confluent drusen occurred, increasing over 3 years to 75% (17%-7%). Nasal and temporal drusen, however, increased 50% in the same time period. SRN subsequently occurred in the temporal drusen. Treatment with argon laser preserved vision of 20/30. Post laser followup was OD 13 years, OS 9 years. In the fellow SRN eye OD, drusen resorbed (5%-2%) centrally as well. Conclusion:Selective resorption of central confluent drusen occurred O.U. after peripheral retinal tear laser repair.
