The standard X-ray preserves its value in verifying the presence of a foreign body (FB). The echography is valuable in verifying the site of a FB when it remains uncertain in respect to the sclera after X-ray localization. Computerized tomography scanning offers useful information about the physical nature of the FB.
The authors present a case of exophthalmos caused by invasion from a hypophyseal tumour, rare both for this type of metastasis and for the patient's young age. Histological study of biopsy material enabled the tumour to be classified. Comparison of clinical and microscopic data helps towards a better understanding of the behaviour of invasive adenomas.
The authors report a case of posterior dislocation of the lens during the natural history of a clinical case of herpes zoster. An echographic B-scan study was carried out to reveal the position and the size and the shape of dislocated lens, together with its structure and that of ocular media. After a discussion on the possible aetiology of the lens dislocation it was considered due to herpes zoster disease, and are reported the possible mechanism of zonula alteration.
