Case Study No. 1
A 46-year-old man presented with a bulging pros-
thetic eye in January 2017 (Figure 3). His prosthesis
had been made 20 years earlier by an ocularist
practice that is no longer in business and he had not
had any check-up visits during that 20-year period.
His eye socket appeared to be badly infected
(Figure 4) and he had superior and inferior eyelid
entropion and lagophthalmos. The posterior of the
prosthesis had a thick coating of protein (Figure 5).
