186. The State maintained that, during his detention in the Federal Prison Service, Lucas Matías Mendoza received medical and psychological care. B.2. Considerations of the Court 187. In the instant case, the Court considers it relevant to underline that, on July 31, 1998, when Lucas Matías Mendoza was hit by the ball, resulting in the detached retina in his left eye, he was awaiting sentencing under the tutelary system in the Dr. Luis Agote Juvenile Institution, and was 17 years of age (supra paras. 98). In this regard, the Court considers it pertinent to recall that any limitation of the physical liberty of an individual, even if this is detention for tutelary purposes, must adhere strictly to the relevant provisions of the American Convention and domestic laws, provided the latter are compatible with the Convention. 253 In this regard, it should be noted that the United Nations Rules for the Protection of Juveniles Deprived of their Liberty state that “[t]he deprivation of liberty means any form of detention or imprisonment or the placement of a person in a public or private custodial setting, from which this person is not permitted to leave at will, by order of any judicial, administrative or other public authority.” 254 188. Accordingly, the Court recalls that, when dealing with persons who have been deprived of liberty, the State is in a special position of guarantor, because prison authorities exercise strong control or command over the persons in their custody, 255 especially if they are minors. Thus, a special relationship and interaction of subordination is created between the person deprived of liberty and the State, characterized by the particular intensity with which the State can regulate his or her rights and obligations, and by the inherent circumstances of imprisonment, where the prisoner is prevented from satisfying, on his own account, a series of basic needs that are essential for leading a decent life. 256 189. This Court has established that the State has the obligation, as guarantor of the health of the persons in its custody, to provide detainees with regular medical examinations and adequate medical treatment when required. 257 In this regard, the Court recalls that numerous decisions of international bodies cite the Standard Minimum Rules for the Treatment of Prisoners in order to interpret the content of the right of persons deprived of liberty to be treated in a dignified and humane manner. 258 Regarding the medical services with which they must be provided, these Rules indicate, inter alia, that “[t]he medical officer shall see and examine every prisoner as soon as possible after his admission and thereafter as necessary, with a view particularly to the discovery of physical or mental illness and the 253 Cf.
