Tapetal hyperreflectivity most strongly indicates which process?

Tapetal hyperreflectivity most strongly indicates which process?

• A. Inherited retinal disease causing atrophy or degeneration
• B. Retinal detachment
• C. Retinal edema
• D. Hyperopia

Answer: (A)

Tapetal hyperreflectivity signals thinning of the neural retina due to degenerative, inherited retinal disease. When the retina loses photoreceptors and outer retinal layers, the underlying reflective tissues (the tapetum or choroid, depending on the species) become more prominent, producing a bright, hyperreflective appearance. This pattern is characteristic of retina that has undergone atrophy or degeneration from a hereditary dystrophy. This isn’t typical of retinal detachment, which presents with a detached, often gray retina and folds or a different refractive appearance; nor of retinal edema, which tends to blur details and reflectivity due to fluid buildup rather than expose a bright, thin-tissue signal; and hyperopia is a refractive issue with no specific fundus hyperreflectivity pattern.
