This is an article regarding a patient presented with bilateraluveitis who was subsequently found to have lung carcinomaon further investigations. We recommend doing a CXRespecially in uveitis patients who have a history of smoking.
INTRODUCTION
Most uveitis cases seen are idiopathic and are not
investigated. Our patient presented with bilateral
uveitis and had previously smoked for more than
45 years. Apart from uveitis he had no other symp-
toms. A chest radiograph was suggestive of lung
carcinoma and fine-needle aspiration biopsy showed
squamous cell carcinoma.
CASE REPORT
An 83-year-old gentleman was referred from the
general practitioner with a first episode of right eye
visual blurring for 1 week. His past medical history
included hypertension, hypercholesterolemia, and
aortic and mitral valve diseases. He was an ex-smoker
with a 45-pack year and worked as an engineer
machinist but with no obvious industrial exposure.
On examination, his visual acuity was VR CF closely
and VL 6/12–6/9 (pinhole correction). He was found
to have bilateral uveitis with cells 2+ flare. There
were fine keratic precipitates on the endothelium of
both corneas. Intraocular pressures were normal.
However there were no iris or ciliary body nodules
and no posterior or peripheral anterior synechiae.
Fundal examination showed wet age macula degen-
eration changes on the right posterior pole and dry
age related macula degeneration on the left fundus. In
view of the severity of his uveitis, investigations were
ordered, including complete blood count (CBC),
erythrocyte sedimentation rate (ESR), rheumatoid
factor (RF), and chest and sacroiliac radiographs. He
was also treated with G Pred forte four times a day.
The uveitis responded to steroid therapy and the
anterior chamber had 1+ cells 1 week later. A follow

The authors present a case of bilateral uveitis in whom a chest radiograph was
suggestive of a lung carcinoma and fine needle aspiration biopsy showed
squamous cell carcinoma. They recommend chest radiography in uveitis pa-
tients with a history of smoking.

up appointment was arranged for treatment of his
age-related macula degeneration but fundal fluores-
cein angiography showed that he would not benefit
from photodynamic therapy.
Chest radiograph showed a lobulated 4.5 cm mass
above the right hilum representing a pulmonary
neoplasm (Fig. 1). Computed axial tomography (CT)
of the thorax was ordered and showed a 6 cm� 4 cm
well-defined lobulated mass at the apex of the right
lung medially which appeared to be surrounding the
superior vena cava and ascending aorta (Fig. 2).
There was possible tumor extension to the superior
vena cava. A few enlarged nodes were seen at the
pretracheal region. There was no liver metastasis.
An anterior chamber tap was done on this patient
after treatment was instituted but no cells were de-
tected from cytology. He was seen by the respiratory
consultant who arranged a fibreoptic bronchoscopy
and a staging CT scan. Histology result from the lung
biopsy revealed squamous cell carcinoma.
DISCUSSION
A four-year old study conducted to show the efficiency
of radiographic screening for detection of sarcoidosis
and anklylosing spondylitis concluded that radiolog-
ical investigations were not useful in the management
of uveitis patients (1). Data from the Cochrane
Database (based on seven trials, six randomized con-
trolled and one non-randomized controlled trial) did
not support screening for lung cancer with chest
radiography or sputum cytology. In fact, frequent
screening with chest radiography might be harmful
and has a 11% relative increase in mortality from lung
cancer compared with less frequent screening (relative
risk = 1.11; 95% CI: 1.00–1.23) (2).
One study confirmed the usefulness of CT scan of
the thorax in elderly female patients who have idio-
pathic chronic uveitis and of which the majority have
normal chest radiographs. Seventy-six percent of
patients with pathology on CT thorax were later
found to have sarcoidosis on biopsy (3).
Fifty percent of patients with anterior uveitis have
related systemic diseases and common associations
include seronegative arthropathies, sarcodosis,
Bechet’s, syphilis, and tuberculosis (4). Common
causes of uveitis with lung-related disorders include
sarcoidosis, connective tissue diseases, for example
Wegener’s granulomatosis, and systemic lupus eryt-
hematosis (5). Lung cancer causing ocular metastasis
has been reported and is not uncommon. However,
metastasis with uveitis as the presenting feature
without any other systemic manifestations has been
documented in a few cases. Tumor metastasis to the
anterior segment is less common than involvement of
the posterior segment. A retrospective review of 420
patients with 950 uveal metastases over a 20-year
Figure 1—Chest X-rays showing the lesion in the right hilum. Comparison of the two X-rays reveals the increase in size of thelesion in the right lung field since the first CXR was taken 4 years ago.

period showed that uveal involvement included the iris
in 90 (9%), ciliary body in 22 (2%), and choroids in 838
(88%). There is a history of a primary cancer in 278
patients (66%) and 142 patients (34%) had no history
of cancer. More than two-thirds of the primary tumor
sites are located at the breast and lung (6).
Approximately 10% of metastasis to the eye in-
volved the anterior segment and patients with anterior
segment metastasis have poorer prognosis and sur-
vival rate than those at the posterior segment or orbit.
In a study of 141 eyes (112 patients) with metastases to
the eye or orbit, lung carcinoma metastasizes earlier
than breast cancer, 276 days compared with 1,266,
and has a shorter median survival time (MST) (188 vs.
666 days) (7). Another study gave a similar median
survival of 5.4 months after surgery in 26 out of 227
patients with metastasis to the anterior segment. Signs
and symptoms produced by the metastatic tumors
involving the anterior segment included decreased
vision (80%), a visible mass (72%), redness of the eye
(56%), glaucoma (56%), iridocylitis (44%), and
hyphema (24%) (8).
There are hypotheses on the causes of anterior
uveitis in patients with ocular metastasis. It may be
due to a systemic inflammatory response as a gener-
alized immune response or it could be due to intra-
ocular metastatic deposits as in neoplastic masquerade
syndrome. Shed tumor cells resembled inflammatory
cells and areas of spontaneous necrosis in tumors
produce inflammatory reaction (9).
No cells were detected in our cytological analysis of
anterior chamber tap. Studies by Woog (10) showed
that a cellular reaction of 3+ is needed to interpret
cytology findings. A negative cytology result on
aqueous does not exclude intraocular malignancy and
it is recommended for other diagnostic evaluations
for example serological markers, immunoperoxidase
staining, and tumor markers of aqueous humor or
vitreous fluids. Fine-needle aspiration biopsy of iris or
ciliary body lesions should be considered. Vitreous
aspiration needle tap may be indicated and this has
been shown to be diagnostic in some patients (11).
More invasive techniques were not done for our
patient in view of his age and because he responded to
topical steroids treatment.
A screening chest radiograph is an invaluable tool
in establishing a diagnosis in patients with uveitis.
Ophthalmologists must be aware that lung pathology
can be a cause of anterior segment inflammation.
