[The diagnosis of ocular sarcoidosis without intrathoracic signs].

Since it is difficult to diagnose ocular sarcoidosis without intrathoracic signs we studied the ocular stage, broncho-alveolar lavage fluid (BALF) and transbronchial lung biopsy (TBLB). Our results showed that we can diagnose such patients as sarcoidosis when BALF lymphocytes are over 20%, the CD4+/CD8+ ratio is over 3.0 and alveolitis is noticed on TBLB. From this point of view, it may be that a diagnosis of clinical sarcoidosis without pathological diagnosis is possible.
