Pattern of Conjunctival Masses Seen At Guinness Eye Centre Luth Idi-Araba
Background: Conjunctival masses are growth on the surface of the outer eye; which may represent benign or malignant transformations.
Objective: To determine the pattern of presentation of conjunctival masses at the Guinness Eye Centre (GEC), Lagos University Teaching Hospital (LUTH) Idi-Araba over a 13 year period (Jan 1995- Dec 2007).
Method: A retrospective review of the clinical notes of all patients that presented to GEC with conjunctival masses during the study period was carried out. The bio-data, clinical features, stage, laterality and associated features of the masses were noted. The diagnosis, treatment and complications of treatment were also recorded.
Results: Case notes of 612 eyes of 393 patients were included in the study. There were 219 (55.7%) males, 174 (44.3%) females with ages ranging from 4-85years with a male to female ratio of 1.26: 1. Three hundred and eightyeight patients (98.7%) presented as elective cases to the outpatient department while 5 (1.3%) presented as emergencies on account of associated ocular inflammation. There were 220 (56%) bilateral masses while 44% were uniocular. Pterygium was the leading conjunctival mass affecting 548 eyes (89.5%) of 329 patients. Pingueculae occurred in 53 eyes (8.7%), conjunctival cysts in 5 (0.8%) eyes, neoplastic growths in 3 (0.5%) eyes, conjunctival granulomas in 2 (0.3%) eyes and limbal teratoma in 1 (0.2%) eye. Most of these patients defaulted from surgery as only 141 eyes (23%) of 121 patients had surgery. Post-operative complications occurred in 33 eyes (5.4%) of 30 patients. The commonest postoperative complication was pterygium recurrence which occurred in 18 eyes of 15 patients.
Conclusion: Pterygium was the commonest conjunctival mass and preventive strategies need to be advocated. Prevention of recurrence remains a challenge in the management of pterygium as recurrence after surgical excision occurred in 13.2% of eyes. Our study however did not confirm outdoor occupations as a risk factor for pterygium.
