GIANT EPITHELIAL INCLUSION CYST 50 YEARS AFTER ENUCLEATION WITHOUT ORBITAL IMPLANT

Background Conjunctival cyst formation following enucleation may occur in 3% to 7% of patients receiving orbital implants, especially second ary implants. We present a patient with a giant epithelial inclusion c yst of the anophthalmic orbit 50 years after enucleation without orbit al implant. Patient A 54-year-old male presented with increasing propt osis of the ocular prosthesis, shallowing of the inferior fornix, a pa lpable orbital mass, and difficulty in retaining the ocular prosthesis . At the age of 1 year enucleation of the right eye without orbital im plant was performed following perforating ocular trauma. Results of ex amination of the other eye were unremarkable. Transillumination of the orbital mass was possible. The clinical diagnosis of an epithelial in clusion cyst was confirmed using ultrasonography and CT scan. An incis ion of conjunctiva and cyst wall and subsequent marsupialization were performed. Nine months postoperatively there was no evidence of recurr ence of the cyst. The ocular prosthesis was well in place. Conclusion Conjunctival cyst formation following enucleation may rarely ocur in p atients receiving orbital implants, especially secondary implants. The presentation of a conjunctival cyst formation following enucleation w ithout obital implant 50 years after surgery is noteworthy in comparis on to implantation cysts which are known to occur more commonly within the first two years following secondary orbital implants.
