§ Mr. Cryerasked the Secretary of State for Social Services (1) how many patients involved in his Department's survey of people suffering from retinitis pigmentosa have received treatment at the Opos clinic in Switzerland; and whether he is yet in a position to make a statement;
(2) whether his Department's survey of people suffering tunnel vision, retinitis pigmentosa, includes those persons who have undergone treatment at the Helmholtz institute in Moscow.
§ Mr. Moyle:I have not asked my Department to conduct a survey but, in the absence of objective evidence that treatment at the Opos clinic in Switzerland has been helpful, I have arranged to have inquiries made into certain individual cases which have been brought to my attention where there is apparent evidence of subjective improvement following this treatment. So far only four such cases have been referred to me and it is too early to draw any conclusions. These inquiries do not include patients who have received treatment at the Helmholtz institute in Moscow.
