Ocular Bleb – Cancer Or Something Else?

0

A 38-year-old man was referred to the clinic for the evaluation of a large and pigmented lesion in the left eye. The patient was suspected of a possible uveal melanoma.

On questioning the patient, he revealed that the growth had developed during the previous several months. Ocular examination showed an elevated and dark brown lesion, measuring 8 mm by 4 mm adjacent to the limbus. In each eye, the best corrected visual acuity was 20/25. A cystic structure communicating with the vitreous cavity was revealed via contact ultrasonographic biomicroscopy. It prompt the diagnosis of a uveal bleb rather than melanoma.

The traumatic bleb formed 10 years following an eye injury

On further open ended questioning, the patient revealed that he met with an eye injury 10 years ago. However, he did not seek any medical care for it. The ophthalmologists concluded that the scleral wall may have been damaged which led to the formation of a uveal bleb.

The patient previously experienced severe episodes of vomiting, which may have caused an increase in the size of the lesion. The patient was under observation for several months, during this time the lesion appeared to be stable.

The patient did not show for any follow-up after 9 months.
