Selective Photocoagulation of Capillary Macroaneurysms by Navigated Focal Laser

Ophthalmic Surg Lasers Imaging Retina. 2021 Jul;52(7):366-373. doi: 10.3928/23258160-20210628-02. Epub 2021 Jul 1.


Background and objective: To evaluate the anatomical and functional outcome of selective photocoagulation of capillary macroaneurysms (CMAs) by navigated focal laser.

Patients and methods: Consecutive patients with solitary or secondary CMAs greater than 150 mm in diameter were included in this analysis. All patients were treated with navigated focal laser and received multimodal imaging.

Results: Seventeen eyes of 17 patients were retrospectively analyzed. Navigated laser photocoagulation of the CMAs successfully occluded 100% of the CMAs, inducing significative improvement in best-corrected visual acuity at 3 (P = .002) and 6 months (P = .001) and a decrease in central macular thickness (CMT) at 3 (P = .0004) and 6 months (P = .0004).

Conclusions: Solitary or secondary CMAs arising from retinal capillaries are candidates for navigated laser treatment. Navigated focal treatment was able to close all CMAs in this series with an improvement in vision and CMT. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:366-373.].
