Definitions
- the present invention relates to a composition for preventing or treating macular degeneration comprising a novel peptide.
- the peptide of the present invention has an effect of inhibiting choroidal neovascularization, which is a major cause of macular degeneration, and has excellent stability and solubility.
- the macula is a part that plays the most important role in the nerve layer of the eye, called the retina, and is the center of the retina having a radius of about 1.5 mm, and photoreceptors that can feel light are concentrated in this part. Therefore, the macula is the center of the retina and is responsible for most of the visual acuity.
- Macular degeneration is a disease in which the macula is degenerated by aging, genetic factors, toxicity, inflammation, and the like. As the macula degenerates, vision is reduced, and in severe cases, vision may be completely lost.
- Macular degeneration is largely divided into non-exudative (dry) and exudative (wet) macular degeneration.
- Non-exudative macular degeneration accounts for 80-90% of all macular degeneration, and most of them do not significantly affect visual acuity except for the late stage when retinal and choroidal atrophy occurs. don't However, caution is needed as it can progress to exudative macular degeneration.
- Exudative macular degeneration accounts for about 10-20% of all cases of macular degeneration, but if left untreated, visual acuity rapidly deteriorates, leading to blindness in many patients within 2 years of diagnosis.
- Exudative macular degeneration is a stage in which choroidal neovascularization occurs, and has a very poor visual prognosis, and is a disease with the highest frequency of blindness in the population aged 65 years or older.
- the vascular layer called the choroid, supplies nutrients to the retinal layer and removes metabolites from retinal cells.
- blood vessels in the choroid pierce through to retinal cells and are abnormally formed.
- abnormal blood vessels are called choroidal neovascularization. Because these blood vessels are abnormal blood vessels, they are very fragile and prone to rupture, causing exudate and blood to flow out, damaging the macular area.
- the treatment of macular degeneration involves taking antioxidant vitamins known to lower the progression of macular degeneration and treating the risk factors of macular degeneration, such as hypertension and hyperlipidemia.
- the risk factors of macular degeneration such as hypertension and hyperlipidemia.
- exudative macular degeneration there are thermal laser photocoagulation, photodynamic therapy, antibody injection, and vitrectomy, but there is no complete treatment yet, and active research is underway.
- a method of injecting anti-VEGF antibodies such as aflibercept, ranibizumab, and bevacizumab into the eye is mainly used, but it requires repeated administration and has disadvantages such as high cost there is
- the present inventors have identified a novel peptide having excellent stability and solubility as well as an excellent effect of inhibiting choroidal neovascularization as a result of research on a substance capable of effectively treating macular degeneration, and completed the present invention.
