Brief Summary
The purpose of this study is to compare the efficacy (times of injection, change of visual acuity and Cva/ I) and safety (macular visual function and choroidal thickness) of different dosing of ranibizumab intravitreal injection (1+PRN vs. 3+PRN) in treating with pathological myopia choroidal neovascularization (PM-CNV).

Study Arms (2)
Group A
ACTIVE COMPARATORGroup A included 30 patients treated with one 0.5mg intravitreal ranibizumab injection. All patients were followed monthly for 12 months with additional injections performed as needed.
Group B
ACTIVE COMPARATORGroup B included 30 patients treated with three monthly 0.5mg intravitreal ranibizumab injections. All patients were followed monthly for 12 months with additional injections performed as needed.
Interventions
Patients received ranibizumab (0.5mg, Novartis AG, Basel, Switzerland) via a pars plana transcleral injection through 30-gauge needle at 3.5 to 4mm of inferotemporal limbus. Levofloxacin eye drops ( Cravit Eye Drops, Santen, Japan) was instilled 4 times a day in the study eye before the treatment at least 1 day. Povidone-iodine (5%, Luofushan Pharmaceutical Co., China) was applied to the conjunctiva bulbi and the fornices for at least 3 minutes before injection. Patients were instructed to continue the levofloxacin eye drops 4 times a day for 3 days
Eligibility Criteria
You may qualify if:
- older then 18 years old
- refractive error ≥ -6.0 diopters or axial length ≥ 26.0mm
- active CNV due to high myopic which is the only reason cause visual loss confirmed by fluorescein fundus angiography
- BCVA ≥ 24.0 and ≤73 letters at a starting distance of 4 meters using Early Treatment Diabetic Retinopathy Study visual acuity chart.
You may not qualify if:
- history of (a) stroke,(b) laser photocoagulation involved macular area in study eye, (c) intraocular treatment with corticosteroids or intraocular surgery or anti vascular endothelial growth factor or verteporfin photodynamic therapy within 6 months in study eye, or (d) hypersensitivity to ranibizumab or fluorescein
- presence of active infectious disease or confirmed intraocular pressure ≥ 21.0 mmHg
- pregnant or nursing women
- uncontrolled high blood pressure ≥ 150/90 mmHg or uncontrolled fasting blood glucose ≥ 7 mmol/L
