title: Demographics of Patients with Double-headed Pterygium and Surgical Outcomes.
abstract: OBJECTIVE
  To analyze demographic and ophthalmologic characteristics of patients with double-headed pterygium in the Mediterranean region of Turkey and to evaluate their surgical outcomes.
  
  
  METHODS
  Records of all patients who underwent surgery for pterygium in Antalya Atatürk State Hospital between November 2012 and March 2014 were retrospectively reviewed. Patients with pterygia on both sides of the cornea (nasal and temporal) were included in the study. Patients with less than six months of follow-up were excluded. Age, occupation and smoking status of patients, recurrence of pterygium and any existing complications in records were evaluated. Fibrovascular proliferation more than 0.5 mm over the cornea was accepted as recurrence.
  
  
  RESULTS
  Eight (5%) of 158 patients who underwent pterygium surgery were diagnosed with double-headed pterygium. Six (75%) of the patients were male and two (25%) were female. Mean age was 42.63 (26-71) years. It was recorded that all patients had worked under the sun for at least 5 hours a day. No intra-operative or post-operative complications were found. Mean follow-up time after surgery was 12 (6-21) months and no recurrence was detected.
  
  
  CONCLUSIONS
  Pterygium, especially double-headed pterygium is mostly seen in warm climates and individuals who work outdoors. Dividing the free conjunctival autograft into two and suturing in place of the excised pterygium on both sides of the cornea is a good choice in these patients.
