OBJECTIVE
To evaluate the efficacy and safety of hypericin-enhanced argon laser photocoagulation (H-ALP) in the treatment of subfoveal choroidal neovascular membrane (CNM) secondary to age-related macular degeneration (ARMD).
METHODS
After preliminary studies for definition of parameters,

St. John's wort (SJW), an over-the-counter antidepressant, contains hypericin, which absorbs light in the UV and visible ranges. In vivo studies have determined that hypericin is phototoxic to skin and our previous in vitro studies with lens tissues have determined that it is potentially phototoxic
Hypericin (HY) is an interesting photosensitizer with dark activity and photodynamic therapy (PDT) effects via p53-independent pathway. In photodynamic diagnosis (PDD) of bladder cancer using HY, very high sensitivity and specificity were reported, in comparison with its counterpart,
Hydroxy and methoxy perylene quinones are synthesized in an attempt to isolate the essential spectroscopic and biological features of light-induced antiviral agents such as hypericin and hypocrellin. Unlike their naturally occurring counterparts, these synthetic quinones bear the carbonyl, hydroxyl,
