abstract：:We briefly review the history and principles of photodynamic therapy (PDT), especially as it is applied to choroidal neovascularization (CNV) in age-related macular degeneration (AMD). After a brief general history of PDT, we discuss the relationship between the physicochemical structure and photodynamic activity of t...

abstract：:The opportunity to perform two or more ophthalmic operations simultaneously has increased in recent years. In keratoplasty too, the simultaneous operation consisting of cataract extraction and IOL insertion (triple procedure) has become common. Penetrating keratoplasty (PKP) and planned extracapsular cataract extracti...

abstract：:Transpupillary thermotherapy (TTT) has been suggested as a putative treatment for choroidal neovascularization (CNV) in age-related macular degeneration (AMD). This prospective study comprised 66 consecutive patients referred for exudative AMD with predominantly occult subfoveal CNV. Based on fluorescein angiography, ...

abstract：:Subfoveal choroidal neovascularization presents one of the most difficult challenges to vision. No treatment option has yet solved the problem of subretinal hemorrhage and fibrovascular scarring causing permanent photoreceptor degeneration and loss. Limited macular translocation provides a surgical approach to this ch...

abstract：:Intraocular gas tamponades are an important part of vitreoretinal surgery and have become a standard of care. The use of intraocular gas began in 1911. Modem use of intraocular gases as a surgical adjunct is continuously broadening. Today, sulfur hexafluoride and perfluoropropane are increasingly being used as intraoc...

abstract：:Conventional suprathreshold retinal photocoagulation is a destructive procedure, but chorioretinal damage can be decreased by changing laser parameters and clinical endpoints. Laser effects can be localized by decreasing laser wavelength, spot size, and exposure duration, as well as by adopting threshold or subthresho...

abstract：:Several new aqueous inflow inhibitors have been introduced over the past few years. These new agents include two alpha agonists, two topical carbonic anhydrase inhibitors, and a novel combination agent. All of these agent compare favorably with timolol in terms of aqueous suppression, though each has its own relative ...

abstract：:Age-related macular degeneration (AMD) is a common cause of legal blindness in the developed countries in people older than 50 years of age. AMD complicated by choroidal neovascular membranes (CNV) accounts for 12% of AMD, but for 88% of legal blindness cases. Because of the progressive aging of the population, it is ...
