GOMEZ CABRERA, Clara Gisela et al. Epidemiological characterization of conjunctival intraepithelial neoplasia in "Ramón Pando Ferrer" Cuban Institute of Ophtalmology. Rev Cubana Oftalmol [online]. 2014, vol.27, n.1, pp.100-108. ISSN 0864-2176.

Objective: to identify the epidemiological pattern of intraepithelial neoplasia of the conjunctiva in the «Ramón Pando Ferrer» Cuban Ophthalmology Institute (2005-2010). Methods: a descriptive study was conducted in 106 patients with unilateral intraepithelial neoplasia by age, sex, associated eye disease and number of years since diagnosis. Percentages, incidence and proportional prevalence rates, and tendency by the graphic method were all estimated. Results: in the study group, 59,4 % (n = 63) were females 53,8 % (n = 57) were 30-39 years old, followed by 33 % of ³ 60 years-olds (n = 35), 18,9 % (n = 20) had associated eye disease with 60 % (n = 12) affected by pterygium. There was 34 % (n = 36), 31,1 % (n = 33) and 30,2 % (n = 32) with CINI, CIN II and CIN III, respectively, and 4,7 % (n = 5) with in situ carcinoma. The incidence rate in 2009 was 3,1 % (n = 34) and 85,8 % prevalence rate (n = 91), with linear tendency to increase. Conclusions: this study showed increasing tendency of the disease, so it must be paid attention to the preventive approach-oriented study of the risk factors to reduce this tendency, taking into account the rise of the life expectancy of the Cuban population and their aging tendencies and the fact that the conjunctival intraepithelial neoplasia is characteristic of the elderly people.
