Abstract

OBJECTIVE:

To determine whether indocyanine green-guided laser photocoagulation of focal spots at the edge of plaques of neovascularization is beneficial for patients with untreatable occult choroidal neovascularization by fluorescein imaging.

PATIENTS:

A pilot series of 23 eyes were identified that had untreatable occult choroidal neovascularization secondary to age-related macular degeneration with focal spots at the edge of a plaque of neovascularization on the indocyanine green study. After informed consent was obtained, indocyanine green-guided laser photocoagulation was applied solely to the focal spot at the edge of the plaque.

RESULTS:

Anatomical success with resolution of the exudative findings was noted in 15 (79%) of 19 eyes at 6 months, 13 (68%) of 19 eyes at 12 months, and six (37.5%) of 16 eyes at 24 months. The median follow-up period was 18 months (range, 3 to 44 months). Visual acuity was stabilized or improved in nine (69%) of 13 successfully treated eyes at 1 year. Of the successfully treated cases at 1 year, nine (69%) of 13 had a final visual acuity of 20/100 or better.

CONCLUSIONS:

Our preliminary study of indocyanine green-guided laser photocoagulation of focal spots at the edge of plaques of neovascularization suggests that this technique may improve the visual prognosis of these patients with presently untreatable disease. A prospective, randomized, controlled clinical trial is warranted to evaluate this treatment approach.
