The vitreous tamponades market is said to be transforming steadily from liquid tamponades to gaseous tamponades, worldwide. Vitreous tamponades are elements used in vitrectomy procedures performed on the human eye that aid in reattaching or healing the retina and provide a substitute to a clouded vitreous humor. Vitreous substitutes are used in the treatment of vitreoretinal disorders and are biocompatible, transparent, and elastic surgical adjuncts. They are used as an intra-operative or as a postoperative mechanism to cure vitreoretinal disorders. In 1970’s, modern vitrectomy techniques were launched and since then the usage of vitreous substitutes has been extensive in reattachment procedures of the retina. Nowadays, the most regularly used vitreous substitutes are silicone oil, perfluorocarbon liquids, and intraocular gases.
The global vitreous tamponades market was valued at US$64.5 million in 2013 and, expanding at a CAGR of 2.5% from 2014 to 2020, is expected to reach US$77.5 million by 2020. Substantial growth of the vitreous tamponades market is seen due to the rising prevalence of diabetic retinopathy, macular pucker, retinal detachments, and other retinal disorders. Globally, an increase in elderly population is also seen as one of the dominant factors likely to augment the demand for vitreous tamponades, as the geriatric population is more vulnerable to retinal breaks and demand immediate care.
Gaseous Tamponades Dominate North America, Liquid Tamponades Rule in Asia and Europe
Gaseous and liquid tamponades amount to a comprehensive commercial market for vitreous tamponades. In 2013, in terms of revenue, liquid tamponades emerged as the leader, accounting for more than 49% of the global market. This preeminence was achieved due to the extensive preference for liquid tamponades over gaseous tamponades in the Asian and European markets to treat retinal disengagement with numerous breaks (superior and inferior), proliferative, giant tears, diabetic retinopathy, and proliferative vitreoretinopathy.
Based on geographical segmentation, the global vitreous tamponades market has been segmented primarily into four major regions: North America, Europe, Asia Pacific, and Rest of the World (RoW). In terms of revenue, North America was the biggest regional market globally in 2013. Due to the on-label use of gaseous tamponades and the comfort of use it provides to physicians and patients, gaseous tamponades accounted for the largest share of the market in North America.
Silicone Oil: The Fastest Growing Segment of the Vitreous Tamponades Market
The liquid tamponades market has been segregated into silicone oil and perfluorocarbon liquid. Among these two, silicone oil has been singled out to be the segment expected to grow rapidly from 2014 to 2020. Silicone oils are commonly called permanent tamponades and are detached from the site in the timeframe of four to six weeks after the surgery. However, because of their low glutinousness and surface tensity, traditional silicone oils tend to become foggy and develop tiny balloons inside the eye, which can lead to ailments such as glaucoma and inflammation.
Such detrimental possibilities have led to the development of silicone oil types with higher glutinousness, in order to lessen the chances of it becoming foggy over time. However, soaring costs of silicone oils compared to gases and the need for a second operation for the elimination of silicone oil several months after the insertion surgery are the key factors likely to hamper the growth of silicone oils in the near future. Perfluorocarbons, on the contrary, are expected to achieve a consistent growth rate, as these tamponades are mainly used for the reattachment of colossal retinal tears.
Key players in vitreous tamponades include both medium and small-sized manufacturers such as Alcon, Inc., Valeant Pharmaceuticals International, Inc., Carl Zeiss Meditec AG, Dutch Ophthalmic Research Center B.V., Fluoron GmbH, Croma Pharma AG, and AL.CHI.MI.A Srl.
