Apple of the eye – Conjunctival Implantation Cyst

Figure 1: Well-defined cystic lesion at nasal limbus- conjunctival implantation cystA 41-year-old gentleman presented to our clinic with a history of a gradually progressive painless mass on the inner aspect of the right eye for the last 13 years. On examination, there was a well-defined cystic lesion measuring 10 mm × 7 mm at the nasal limbus in the right eye [Fig. 1] with a pterygium in the left eye. The rest of the anterior and posterior segment examination was unremarkable with a visual acuity of 20/20 in both eyes. Intraocular extension and involvement of other ocular structures were ruled out on ultrasound biomicroscopy. A provisional diagnosis of conjunctival implantation cyst was made. The patient underwent an excision biopsy with a conjunctival autograft harvested from the same eye. The diagnosis of conjunctival implantation cyst was confirmed on histopathological examination of the specimen, which showed an epithelium-lined cyst under the conjunctival epithelium. A few inflammatory cells were also seen in the subconjunctival space, suggesting the role of inflammation in the pathogenesis of the cyst.[1] On follow-up visits, the conjunctival autograft was taken up well and the patient maintained a stable ocular surface.
