Vitreous tamponades are used to provide surface tension across retinal breaks, which prevents further fluid flow into the subretinal space until the retinopexy provides a permanent seal. Gases and silicone oils are the most commonly used classes of tamponade agents. Silicone oils are permanent and remain in the eye until surgically removed.
High prevalence of various retinal diseases is expected to propel growth of the vitreous tamponades market. According to the study ‘Global causes of blindness and distance vision impairment 1990-2020: a systematic review and meta-analysis’, published in the journal Lancet, in 2015, 2.6 million people were visually impaired because of diabetic retinopathy, and the number is expected to reach 3.2 million in 2020.
Prevalence of diabetes plays a major role in risk of diabetic retinopathy According to the study, “Global and regional diabetes prevalence estimates for 2019 and projections for 2030 and 2045: Results from the International Diabetes Federation Diabetes Atlas, 9th edition”, published in the journal Diabetes Research and Clinical Practice, in September 2019, 463 million people are expected to suffer from diabetes in 2019 worldwide and the number is expected to reach 578 million by 2030 and 700 million by 2045.
Vitreous tamponades are used in the treatment of retinal detachment. The most common gas tamponades used in the U.S. are air, SF6, and perfluoropropane (C3F8). In the U.S., the number of people in the U.S. suffering from diabetic retinopathy is expected to reach 14.6 million in 2050 from 7.7 million in 2010, according to the Centers for Disease Control and Prevention. Such scenario is expected to aid in growth of the vitreous tamponades market.
Use of vitreous tamponades is associated with several important complications such as chronic postoperative elevated intraocular pressure and hypotony. Other complications include, corneal edema, corneal opacity, or need for corneal transplant. Moreover, silicone oils and gases provide less effective tamponade for cases with inferior retinal breaks and conventional silicone oils are relatively less effective in the treatment of inferior retinal detachment. Such side effects are expected to hinder growth of the vitreous tamponades market.
Geriatric population is prone to various retinal diseases. According to United Nations Population Fund, geriatric population in Asia Pacific is expected to triple between 2010 and 2050 to reach 1.3 billion people by 2050. Asia Pacific is thus expected to witness significant growth in the vitreous tamponades market.
