ABSTRACT
PURPOSE:
To report the clinical presentation, anterior segment optical coherence tomography features, treatment, and outcomes of ocular surface squamous neoplasia (OSSN) associated with pterygium.METHODS:
Retrospective interventional series of 14 cases in a 28-month study period.RESULTS:
OSSN was coexistent with pterygium (n = 14) in < 1% of all pterygia (n = 7384). The mean age at the presentation of OSSN with pterygium was 49 years (median, 49 years; range, 36 to 71 years). Referral diagnosis included pterygium sans OSSN (n = 7, 50%), granuloma (n = 1, 7%), actinic keratosis (n = 1, 7%), and conjunctivitis (n = 1, 7%). All OSSNs were unilateral, and six patients (43%) had bilateral pterygia. Tumors arose from the nasal (n = 8, 57%), or temporal (n = 6, 43%) quadrants. The mean tumor diameter was 4 mm (median, 4 mm; range, 2 to 6 mm), and the mean thickness was 2 mm (median, 1 mm; range, 1 to 3 mm). The delineation between OSSN and pterygium could be identified on anterior segment optical coherence tomography (AS-OCT) in all (100%) cases. All patients received 1% topical 5-fluorouracil (5-FU), and complete tumor regression was achieved in 13 (93%) cases with a mean number of 2 cycles (median, two cycles; range, 1 to 4 cycles). There were no significant adverse effects. No tumor recurrence was noted over a mean follow-up period of 11 months (median 12 months; range, 1 to 4 months).CONCLUSION:
AS-OCT allows accurate detection and mapping of tumor extent in OSSN with coexistent pterygium, and topical 5-FU yields excellent tumor control.
