Excision of conjunctival cysts, naevi, and suspicious lesions
The conjunctiva is the thin, transparent membrane covering the white of the eye. It can develop a variety of lesions including cysts, pigmented naevi, papillomas, lymphangiomas, and occasionally more serious growths such as ocular surface squamous neoplasia. While most lesions are benign, any new, growing, or changing lesion should be assessed by a specialist.
At Vale Eye Surgeons, conjunctival lesion removal is performed by a trained surgeon. We have access to histopathology services to confirm the diagnosis whenever clinically indicated.
Under the operating microscope, the lesion is carefully excised with a margin of healthy tissue where clinically appropriate. For pigmented or potentially atypical lesions, a wider excision may be performed and the defect closed with a conjunctival graft or amniotic membrane patch. When indicated, the excised tissue is sent for histological examination to confirm the diagnosis.
Detailed slit lamp examination with photographic documentation so any changes can be tracked over time. Anterior segment OCT may be used to assess the depth of the lesion. Your surgeon will advise whether observation, biopsy, or complete excision is most appropriate.
Most lesions are removed under local anaesthetic as a day case, typically taking 15-20 minutes. You will be awake but comfortable. The eye is protected with a pad at the end of the procedure.
Expect mild discomfort and redness for a few days. Antibiotic and anti-inflammatory drops are prescribed. Most patients return to normal activities within 48 hours. If a sample was sent for analysis, histology results are typically available within two weeks and will be discussed at your follow-up appointment.
You should be seen promptly if you notice a new lesion on the white of the eye, a pigmented spot that is changing in size or colour, or any lesion that is bleeding, ulcerating, or causing persistent irritation. Early assessment provides peace of mind and, where needed, allows treatment before any lesion becomes more difficult to manage.
