Photodynamic therapy for juxtafoveal choroidal neovascularization due to ocular histoplasmosis syndrome.

Retina 2005 January
PURPOSE: To report the use of photodynamic therapy with verteporfin in patients with juxtafoveal choroidal neovascularization (CNV) for ocular histoplasmosis syndrome (OHS).

METHODS: Retrospective review. Data regarding the following variables were extracted from patient charts: demographic characteristics, previous surgeries, angiographic features, number and time of treatments, follow-up time, and change in visual acuity.

RESULTS: This study sample consisted of 23 eyes of 23 consecutive patients who were treated with photodynamic therapy for the management of juxtafoveal CNV. When post-treatment visual acuity (mean logMAR acuity=0.321) was compared to baseline acuity (mean logMAR visual acuity=3.89) vision improved by more than three Snellen lines in 30% of eyes, remained the same (+/-2 Snellen lines) in 52% of eyes, and worsened (greater than a two-line loss in visual acuity) in 18% of eyes. Although this series was uncontrolled, the patients had a trend toward a therapeutic benefit when compared to published natural history of similar cases (OR=0.292, P value=0.071 when compared to data from the Macular Photocoagulation Study for treatment of juxtafoveal lesions).

CONCLUSION: Photodynamic therapy with verteporfin may be beneficial in patients with juxtafoveal CNV secondary to OHS in terms of both visual stabilization and improvement.
