One-year results of bevacizumab intravitreal and posterior sub-Tenon injection of triamcinolone acetonide with reduced laser fluence photodynamic therapy for retinal angiomatous proliferation.

PURPOSE

Our aim was to study the efficacy of combined triple therapy with intravitreal bevacizumab injections (IVB), posterior sub-Tenon injection of triamcinolone acetonide (STTA), and reduced laser fluence photodynamic therapy (RFPDT) in Japanese patients with retinal angiomatous proliferation (RAP).

DESIGN

This was a retrospective, observational, consecutive case series.

METHODS

Fifteen consecutive RAP treatment-naïve eyes were treated with triple therapy of IVB, STTA, and RFPDT (25 J/cm(2) of laser fluence). Whenever there was a recurrence of retinal-retinal anastomosis (RRA) or retinal-choroidal anastomosis (RCA) and marked leakage from subretinal neovascularization, the triple therapy was reapplied. When there were only intraretinal exudative and/or hemorrhagic changes without distinct RRA or RCA, IVB alone was applied.

RESULTS

The mean logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) at baseline improved significantly (from 0.489 to 0.294 12 months) (paired t test, p = 0.043). LogMAR BCVA at 12 months was stable or improved by ≥ 0.2 in 14 eyes (93.3 %). Mean number of triple therapy instituted during the 12-month study period was 1.2, and mean number of IVB treatments was 1.4.

CONCLUSION

Combined IVB, STTA, and RFPDT for RAP was effective in maintaining or improving VA at 1 year. In addition, the number of treatments could be markedly reduced.
