Primary Outcome Measures:
  • Resolution time of intraretinal cysts and sub retinal fluid on OCT [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Mean change in OCT central foveal thickness [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • The percentage of subjects with no fluid on OCT [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • The percentage of subjects who lose less than 15 letters of visual acuity [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • The percentage of subjects who gain greater than or equal to 15 letters of visual acuity [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • Mean change in visual acuity [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • Mean change in macular volume [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • Quantitative change in area (microns) from baseline in choroidal neovascular lesion characteristics/size as measured by ICG/FA/Fundus photos [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • Mean number of injections of 2.0 mg intravitreal aflibercept injection [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Intravitreal Aflibercept injection
Intravitreal Aflibercept injection 2.0 mg dosed every 4 weeks (monthly) for the first 3 months followed by 2.0 mg (0.05mg) via intravitreal injection once every 8 weeks (2 months).
Drug: Intravitreal Aflibercept injection
Intravitreal Aflibercept injection 2.0 mg dosed every 4 weeks (monthly) for the first 3 months followed by 2.0 mg (0.05mL) via intravitreal injection once every 8 weeks (2 months). Dosing at monthly intervals is allowed if needed in the opinion of the investigator based on presence of fluid on OCT and/or a decrease in visual acuity of 5 letters or more from the best previous visit.

Detailed Description:

Twenty (20) consented participant who meet the inclusion criteria will be enrolled to be followed for 48 weeks. All subjects will receive 2.0 mg intravitreal aflibercept injections with three initial monthly doses, and mandatory doses at Weeks 16, 24, 32, and 40. Dosing at monthly intervals is allowed if needed in the opinion of the investigator based on presence of fluid on Optical Coherence Tomography (OCT) and/or a decrease in visual acuity of greater than or equal to 5 letters from the best previous visit. Only one eye will be enrolled in the study.
