An emaciated alcoholic 52-year-old white woman presented with an old left corneal perforation and bilateral conjunctival and corneal xerosis. The serum vitamin A level was 0 mumol/L. Laboratory and radiologic findings were consistent with the diagnosis of a fat malabsorptive syndrome secondary to chronic alcoholic pancreatitis. Histopathologic evaluation of her enucleated globe revealed conjunctival epidermidalization, corneal perforation with prolapse and loss of intraocular contents,
retinal detachment
, and massive choroidal hemorrhage. A second patient presented with bilateral conjunctival xerosis, corneal ulcers, and a low serum vitamin A level. Corneal perforation of one ulcer ensued during her hospitalization. Medical investigation revealed hepatic
metastases
of an unknown primary source. Causes of vitamin A deficiency and its ocular complications as well as medical and surgical management options are discussed.

A total of 161 cases of choroidal
metastases
are reviewed. Breast or bronchial carcinomas are the most frequent primary tumors. One-third of the patients develop bilateral choroidal
metastases
. In 67% of all cases metastatic choroidal lesions were found in the posterior pole. Eighty-nine percent of all patients had a history of malignant tumor, in 11% of all patients choroidal metastasis was the first sign of a primary carcinoma elsewhere in the body. Sixty percent of all patients with choroidal
metastases
had additional other distant
metastases
at the time of diagnosis of choroidal involvement. The survival rate is poor: 50% of all patients with choroidal metastasis had died 1 year later. In 35% of all patients, choroidal
metastases
occurred despite prior systemic therapy with cytotoxic drugs or hormone therapy. In many cases the spontaneously course leads to irreversible loss of central visual acuity due to tumor growth, tumor necrosis or the complications of an exudative
retinal detachment
. Early fractionated external beam in radiation may prevent this outcome. The clinical course in 71 eyes following irradiation is reported. In 80% radiation therapy led to regression or eradication of the tumor, and a vision of at least 0.4 was maintained in 61% of the treated eyes.

With binocular indirect ophthalmoscopy, fluorescin angiography and ultrasonography 68 choroidal
metastases
in 52 eyes of 39 patients were diagnosed. The primary tumors were mainly breast cancer (81%) and lung cancer (10%). After radiation treatment the visual acuity improved in 17 eyes (38%), stabilized in 15 eyes (33%), whereas in 13 eyes (29%) deterioration could not be prevented (seven eyes unknown). Regression of the lesions or its accompanying secondary
retinal detachment
was seen in 78% of the eyes treated. Acute transient side effects of radiation therapy were kerato-conjunctivitis (nine patients) and acute glaucoma in one patient. No cataractous changes of the lens were observed in the post radiation period (one to 42 months). Irradiation of choroidal
metastases
can contribute to improvement of the quality of life with a treatment scheme of 30 Gy in ten daily fractions.

The electro-oculogram (EOG) in the 64 patients with a melanoma of the choroid or ciliary body was compared to the EOG in 11 patients with choroidal metastasis, 11 patients with choroidal naevi and 27 patients with a rhegmatogenous
retinal detachment
. Using the Dt and the Lp/Dt-ratio, 87.5% of the melanomas could be diagnosed correctly whereas choroidal naevus and
retinal detachment
were diagnosed correctly in 72.7% and 70.4% of the cases respectively. Choroidal
metastases
never were classified correctly. Accompanying
retinal detachment
, tumour volume or a break through Bruch's membrane had no influence on the EOG in the melanoma patients. An important advantage of the method is that it can be used irrespective of the condition of the other eye. Combined with ophthalmoscopy, ultrasonography and fluorescein-angiography the EOG can be an additional aid in the differential diagnosis of malignant melanoma of the choroid and ciliary body.

Sixty-seven ocular tumors were studied with magnetic resonance (MR) imaging and computed tomography (CT). These tumors included primary uveal melanoma (n = 55), circumscribed choroidal hemangioma (n = 3), diffuse choroidal hemangioma (n = 1), retinal capillary hemangioma (n = 1), medulloepithelioma (n = 1), choroidal nevus (n = 1), retinoblastoma (n = 1), and choroidal
metastases
(n = 4). MR imaging demonstrated all these lesions, while CT demonstrated 88%. Associated
retinal detachment
was more easily distinguished from the neoplasms with MR imaging. Extrascleral extension of melanoma and hemorrhagic cystic necrosis within the melanoma were clearly demonstrated with MR imaging, but not with CT. Ninety-three percent of melanomas were markedly hyperintense, compared with the intensity of the vitreous body, on T1-weighted images and hypointense on T2-weighted images. All metastatic lesions were isointense on T1-weighted images and hypointense on T2-weighted images. The circumscribed choroidal hemangiomas were hyperintense on T1-weighted images and isointense on T2-weighted images. MR imaging is superior to CT in detection of intraocular tumors and may be more specific in diagnosis.

The mode of presentation of ciliary body tumours, their investigation and management are described. The results in 60 such tumours treated by local excision over a 16 year period are reported. The mean follow-up in these cases is 34 months (median: 14 months, range: 1 to 196 months). The eyes were preserved in 47 patients (78 per cent). In these cases the vision was Counting Fingers or better in 34 (72 per cent) and 6/18 or better in 15 (32 per cent). The most serious complications were vitreous haemorrhage (40 per cent),
retinal detachment
(26 per cent) and residual tumour (20 per cent). Nine patients (15 per cent) have developed
metastatic disease
.

Twenty-two patients, who were suspected of an intraocular tumour, were examined with the high resolution thin slice CT-scan (1.5 or 3 mm slices). The final diagnosis in 14 cases was an uveal melanoma, and in 3 cases in which an uveal melanoma was suspected a chorioretinal haemorrhage, an exudative macular degeneration type Junius Kuhnt and an intrascleral foreign body were respectively found. In 2 cases intraocular
metastases
were demonstrated, and in 2 other cases malignant lymphomata. One patient had a haemangioma. In 10 of the 14 patients with uveal melanomata enucleation was performed and 4 were treated by ruthenium application. The CT-scan was compared with ultrasonographic, operative and histological findings. From the study it appears that the CT-scan is useful for screening uveal melanomas. It is however difficult to distinguish the uveal melanoma from a secondary
retinal detachment
; differentiation from an exudative macular degeneration was not possible. The size of the tumour was only represented correctly on the CT-scan in half the cases. CT examination fails to demonstrate or exclude epi- and extrascleral growth. The multiple
metastases
and the haemangioma could only be seen with difficulty on the CT-scan; the latter was however clearly visible after the injection of contrast. The foreign body could be clearly seen without contrast.

The predictive value of prognostic factors is of utmost importance for the treatment of patients with retinoblastoma. Functional results, that may be expected following sight saving therapy, can be deducted from ophthalmoscopic findings. Large tumors, tumors located centrally, the presence of extensive
retinal detachment
or diffuse vitreous seeding are poor prognostic signs. Histopathologic findings of the enucleated eye harbouring retinoblastoma correlate well with the incidence of
metastatic disease
. Patients in which the tumor has invaded the choroid, optic nerve or sclera have a high risk of developing
metastases
.

A case of pigmented choroidal lesion coincident with rhegmatogenous
retinal detachment
was observed. The patient refused enucleation, and the
retinal detachment
was successfully treated by diathermy without drainage of subretinal fluid. Clinically the lesion was observed to enlarge, and upon enucleation five years after diathermy the tumor was seen to be a spindle-cell choroidal melanoma. The patient died from
metastases
of melanoma six years after the enucleation.

Helium ion irradiation is a promising alternative therapy for choroidal melanoma. In short-term follow-up (less than 5 years), more than 90% (18/19) of treated patients demonstrated tumor regression. We had to enucleate five eyes after helium ion therapy either because of continued tumor growth (four patients) or other complications (one patient). Two melanomas continued to grow and seemed to be radioresistant. In two other tumors it retrospectively seemed that the entire lesion was not inside the radiation field. In one patient total
retinal detachment
and glaucoma developed; enucleation was performed because of a painful eye.
Metastatic disease
developed in no patients. The treatment failures emphasize that there are a number of unresolved issues regarding the use of charged-particle irradiation in the treatment of melanoma. Further studies must be performed to answer these questions and better delineate the use of these newer forms of therapy.
