Is it obligatory to inform a suitor about a slight possibility of having multiple sclerosis, considering that optic neuritis might be viral and doctors have ruled out the disease?

Scholars have differed regarding the defects in marriage that must be disclosed. The majority confined them to defects that prevent intimacy, while others held that any defect that alienates one spouse from the other and prevents the realization of the marriage's purpose necessitates the option (of annulment), and this is the preponderant view. This is regulated by three matters: that the illness affects conjugal life and the rights of the spouse and children, or alienates the spouse; and that it is real and permanent, not imaginary or temporary. Based on this, there is no obligation to disclose optic neuritis if it has been treated, nor a potential illness that has not been confirmed.
