Alström Syndrome is a rare multi-system condition, and it’s often the loss of vision that families notice first — sometimes long before any other feature of the syndrome becomes apparent. Interestingly, it runs opposite to Bardet-Biedl Syndrome in how the retina is affected: rather than a rod-first pattern, Alström typically produces a cone-rod dystrophy, meaning central and colour vision suffer relatively early.
For Zimbabwean families, we approach this as the whole-body condition it is from the outset — coordinating with whatever local specialists are already managing the syndrome’s other systemic aspects, while our own work concentrates on the cone-rod retinal pattern that distinguishes Alström from other inherited dystrophies.

“That’s characteristic of Alström Syndrome specifically — it follows a cone-rod course, so central and colour vision are affected relatively early, unlike the rod-first pattern seen in classic retinitis pigmentosa.”
”
They share some systemic features but are caused by different genes and follow different retinal patterns — Alström affects central vision earlier via a cone-rod pattern, while Bardet-Biedl follows the rod-first pattern seen in classic RP. Genetic testing distinguishes between them clearly.”
“Alström Syndrome can involve the heart, hearing, and metabolic function, so ongoing coordination with the relevant specialists in Zimbabwe stays important alongside the retinal care we provide.”
“No minimum age applies. Because visual symptoms often appear so early with this condition, getting a baseline assessment done early gives us something concrete to measure future change against.”
