Occult with no classic choroidal neovascularization secondary to age-related macular degeneration treated by intravitreal triamcinolone and photodynamic therapy with verteporfin.
OBJECTIVE
To examine combined treatment with intravitreal triamcinolone acetonide (IVT) and photodynamic therapy (PDT) for occult with no classic choroidal neovascularization (CNV) secondary to age-related macular degeneration.


METHODS
In this prospective, interventional case series, 11 eyes of 10 consecutive patients with occult with no classic CNV underwent a single injection (25 mg) of IVT followed 1 month later by PDT. Best-corrected visual acuity was measured by Early Treatment Diabetic Retinopathy Study (ETDRS) protocol refraction.


RESULTS
Median best-corrected visual acuity was 20/160, 20/80, 20/80, 20/50, and 20/80 at baseline and 1, 3, 6, and 12 months, respectively. Best-corrected visual acuity at baseline was statistically different (P < 0.05) than best-corrected visual acuity at 1, 3, and 6 months. Of 11 eyes, 5 (45.5%), 7 (63.6%), 7 (63.6%), and 4 (36.3%) had improved best-corrected visual acuity of at least 3 ETDRS lines at 1, 3, 6, and 12 months, respectively, while 6 (54.5%), 9 (81.8%), 10 (91%), and 8 (73%) had improved best-corrected visual acuity of at least 2 ETDRS lines at 1, 3, 6, and 12 months, respectively. Two eyes (18%) lost >3 lines at 12 months. One eye had intraocular hypertension at 3 months and was treated with a combination of topical antiglaucomatous drugs. One eye developed a dense cataract at the last follow-up visit. No endophthalmitis, retinal detachment, or vitreous hemorrhage developed. Fluorescein leakage and retinal thickness reduced significantly after treatment.


CONCLUSIONS
Improvement of best-corrected visual acuity and lack of fluorescein leakage suggest combination treatment with IVT and PDT for occult with no classic CNV merits further investigation.
