Abstract
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.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.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.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.
