Topical treatment with cysteamine eye drops prevents progression of deposits and may decrease it with adequate compliance.

Further follow up is still recommended to monitor long term effects of both systemic and topical cysteamine therapy.

The results indicate that cysteamine improves laying performance of hens and affects the early posthatch growth of broiler offspring, in a sex-specific fashion.

In addition to oral cysteamine, cysteamine eye drops were provided to all diagnosed patients and CCCS was followed up on a quarterly basis.

These results provide the rationale for a combination therapy of CF in which pretreatment with cystamine or cysteamine enables the later action of CFTR potentiators.

Cysteamine has been reported to modulate energy homeostasis and exert significant growth-promoting effects in broiler chickens.
