Active Comparator: Standard of Care Sildenafil
Medical record review for participants that are prescribed Sildenafil off-label as part of standard of care treatment for disease.
Other: Standard of Care Sildenafil
Medical record review of participants that receive Sildenafil as part of standard of care.
Active Comparator: Sildenafil
Participants are prescribed sildenafil 40-80 mg daily.
Initial Sildenafil dosage will be weight dependent. Participants will start at 40 mg daily (20mg in the morning, 20 mg in the evening) or 60 mg daily (40mg in the morning and 20 mg in the evening). Sildenafil dosage may be increased to up to 80mg daily (20-40mg in the morning and 20-40mg in the evening) based on the response to lower doses. If the participant has not had improvement after initial treatment, the dose may be increased, at the discretion of the study physician.
Diagnostic Test: Ocular Coherence Tomography-Angiography (OCT-A)
Retinal photographs will be taken at each study visit.
Other: Visual Acuity (VA)
Visual acuity will be measured with Snellen Eye Chart at each study visit.
- Change in Choroidal Perfusion [ Time Frame: Up to 5 Years ]Patients are evaluated for progression of disease/dystrophy via visual acuity (improved/stable/worsened) and appearance of fluid layer and drusen on OCT testing.
