01 Rising Prevalence of Eye Disorders The main factors contributing to visual impairment and blindness worldwide are eye diseases like cataracts, age-related macular degeneration, glaucoma, and diabetic retinopathy. The number of people with visual issues and blindness rises proportionately as the older population grows. In addition, lifestyle changes have increased the incidence of various diseases that cause visual impairment, such as diabetes and hypertension. As per a WHO report published in 2019, an estimated 2.2 million people suffer from eye disorders globally, of which 1 million cases could have been prevented or are still undiagnosed.The most common types of eye disorders reported are presbyopia (826 million), refractive error (123.7 million), glaucoma (6.9 million), cataract (65.2 million), corneal opacities (4.2 million), trachoma (2 million), and diabetic retinopathy (3 million). The abovementioned statistics represent the overall eye disease burden globally, contributing to the growing demand for pupillometer machines. Moreover, ophthalmic disorders, such as childhood blindness, age-related macular degeneration, trachoma, corneal opacities, and onchocerciasis, are expected to witness the highest incidence over the forecast period.
02 Increasing Number of Neurological Disorders Neurological disorders, including Alzheimer's disease, dementia, stroke, and epilepsy, are the fifth major cause of death globally and cause 5.53% of deaths worldwide. According to WHO, the prevalence of comorbidities such as tension-type headaches, migraine, medication overuse headaches, and Alzheimer's disease, including other dementias, is 1505.9 million, 958.8 million, 58.5 million, and 46.0 million, respectively.Global statistics indicate that the prevalence of epilepsy is around 50 million, cerebrovascular disease is around 62 million, migraine is around 326, and Alzheimer's disease and other dementias is around 24 million. As per WHO, the number of deaths due to neurological conditions in 2019 was 533,172, of which 40%, i.e., 213,129, were men and 60%, i.e., 320,043, were women. These conditions account for 32.9 deaths per 100,000 population (age-standardized), 33.1 deaths per 100,000 in men, and 32.2 deaths per 100,000 in women. The abovementioned stats suggest that the prevalence of neurological disorders is growing, which is expected to fuel the growth of the pupillometer market.
01 Challenges Associated with the Usage of Pupillometer A pupillometer is a device used to measure the distance between pupils through visual stimuli. However, measuring a child's pupillary distance is difficult, as their eyes usually converge when the machine is placed before them. This leads to the generation of inaccurate Pupillary Distance (PD) readings. Hence, capturing a kid's attention for a longer duration to measure PD can be challenging.Furthermore, if the dispenser or patient cannot close the other eye while measuring PD, then PD measurement can be inaccurate. Strabismus (crossed eyes), a disease in which one eye is focused in a different direction compared to the other, poses a significant challenge for the pupillometer for measuring PD in strabismic patients. It is estimated that 4% of the U.S. population, or about 13 million people, have strabismus, thereby hampering the market growth.
01 Favorable Government Policies Increasing government initiatives to create awareness about visual impairments is expected to boost the market over the forecast period. As per WHO, in 2017, the number of visually disabled people was 180 million worldwide, of which 40 million to 45 million were blind and could not function independently. They needed social and vocational support. An increase in the incidence of visual impairment also poses a social and economic problem, primarily in developing economies, where nine out of 10 people are visually impaired. China, sub-Saharan Africa, and India account for approximately 60% of the total.Additionally, cataracts cause blindness in approximately half of all blind people. The remaining includes people suffering from trachoma, glaucoma, onchocerciasis, and other conditions affecting children. The increase in the general and geriatric population is the main reason for the high global burden of blindness, despite efforts to control the growing prevalence of trachoma. It was predicted that if extra precautions were not taken, the burden of blindness would treble globally by 2020, particularly in developing economies. For instance, a global movement called VISION 2020 aims to increase public and governmental awareness of the effects of blindness. The necessity for human and financial resources to eradicate blindness must be persuaded by international decision-makers and NGOs. Such government initiatives are expected to create opportunities for market growth.
