Abstract
PURPOSE
To assess the effects of intravitreal ranibizumab injection in patients affected by pigment epithelial detachment associated with occult subfoveal choroidal neovascularization.
DESIGN
Prospective, interventional case series.
METHODS
PARTICIPANTS
Forty eyes of 40 patients were considered for the purpose of the study. Consecutive patients were recruited for a 24-month study. All patients underwent a complete ophthalmic examination, including best-corrected visual acuity on Early Treatment Diabetic Retinopathy Study (ETDRS) charts. After a 3-monthly loading phase, further intravitreal ranibizumab injections were administered on the basis of detection of any type of fluid on optical coherence tomography.
PRIMARY OUTCOME MEASURES
Changes in mean best-corrected visual acuity at 12 and 24 months and the proportion of eyes losing fewer than 15 letters (corresponding to 3 ETDRS lines) from baseline visual acuity.
SECONDARY OUTCOME MEASURES
Changes in central macular thickness on optical coherence tomography and variation in mean area of the entire lesion.
RESULTS
Forty patients were included. Mean best-corrected visual acuity decreased from 20/66 (58 ETDRS letters) to 20/83 (53 letters) at 12 months and 20/112 (489 ETDRS letters) at 24 months (P = .003). Eighty percent and 67.5% of eyes lost fewer than 3 lines at 12 and 24 months, respectively. Mean central macular thickness passed from 545 μm to 428 μm at 12 months and 426 μm at 24 months. Mean lesion area changed from 6826 μm(2) to 6312 μm(2) at 12 months and 6010 μm(2) at 24 months.
CONCLUSIONS
The treatment of pigment epithelial detachment associated with occult subfoveal choroidal neovascularization with intravitreal ranibizumab injection after a 3-monthly loading phase and pro re nata strategy can lead to partial results over a 24-month follow-up. Further investigations are warranted to establish the best therapeutic approach to this disease.
