Cone-rod Dystrophy: Introduction

  • Cone-rod dystrophy is a heterogeneous group of inherited retinal diseases characterized by cone photoreceptor degeneration, which could be followed by subsequent rod photoreceptor loss. These disorders typically present with progressive loss of central vision, color vision disturbance, and photophobia.
  • Cone photoreceptor cells are present throughout the retina, but are concentrated in the central region (the macula). These are useful for central (reading) vision. Rod photoreceptor cells are present throughout the retina, except for the very center, and help with night vision.
  • During the initial stages of the onset of disease, which typically occurs from childhood itself, a patient experiences difficulty with vision clarity, problems with color vision, and light sensitivity. As the disease progresses, blind spots in the field of vision can occur. These symptoms occur due to the progressive deterioration of cone photoreceptor cells. This is followed by a progressive loss of rod photoreceptor cells, which leads to a loss of side vision and night blindness.
  • Cone-rod dystrophy is a genetically inherited disorder. Multiple genes can cause cone-rod dystrophies. Genes linked with this condition include ABCA4, CRX, GUCY2D, and RPGR.

Key Drivers and Restraints of Global Cone-rod Dystrophy Treatment Market

  • Cone-rod dystrophy is a progressive disease. Diabetes is one of the major risk factors for cone-rod dystrophy. Rapid rise in the global diabetic population is anticipated to boost the growth of the global cone-rod dystrophy treatment market. High blood glucose can lead to diabetic retinopathy, in which the retinal blood vessels are damaged. This can accelerate the disease progression.
  • Progression of eye disorders is faster in a diabetic person than in a non-diabetic. Lifestyle changes have led to an increase in the diabetes population, which in turn has driven the incidence of cone-rod dystrophy.
  • Gene replacement therapy involves replacing a mutated gene, which causes the disease, with a healthy gene. It is a technique used to treat or prevent a particular disease caused by genetic mutation. In eye disorders such as cone-rod dystrophy and glaucoma, gene replacement therapy is used to improve visual capability in inherited retina disease. Gene replacement therapy and gene knockdown are presently being explored in inherited eye disorders by reversing the mutation.
  • However, lack of disease awareness leading to slow or late diagnosis of patients in developing and under-developed countries is anticipated to hamper market growth during the forecast period
