Advancing wavelike epitheliopathy after conjunctival intraepithelial neoplasia. Atipical case report.

An atypical Advancing Wavelike Epitheliopathy case, consecutive to topical treatment for a 360º Conjunctival Intraepithelial Neoplasia, is presented. Mitomycin (0.2 mg/mL) and interferon (1 MUI/mL) drops were used. An atypical presentation, with migrating limbal focus, non clearly delimited in its hourly site through its evolution. Treated with flurometholone drops plus artificial tears, working to complete resolution.

High resolution anterior segment optical coherence tomography for differential diagnosis between corneo-conjunctival intraepithelial neoplasia and pterygium. / Tomografía de coherencia óptica de segmento anterior de alta resolución como método de diagnóstico diferencial entre neoplasia intraepitelial córneo-conjuntival y pterygium.

OBJECTIVE: To assess if anterior segment optical coherence tomography (AS-OCT) is a noninvasive diagnostic method suitable to differentiate benign corneo-conjunctival lesions (pterygium) from premalignant lesions (corneo-conjunctival intraepithelial neoplasia, CIN). MATERIAL AND METHODS: An observational, analytical and cross-sectional study was conducted in 22 eyes with conjunctival lesions clinically suspicious for pterygium and CIN during two years. Morphological differences between both lesions were studied with AS-OCT; epithelial thicknesses (EE) and extension length on corneal surface (GIC) were compared between both groups. A surgical excision of the lesion was performed for histopathological diagnosis. RESULTS: Mean age of patients with pterygium (n=18) was 52.67±15 y.o and 74±12 y.o in subjects with CIN (n=4) (p<0.021). In pterygia, AS-OCT showed typical features (normal, thinning or slightly thickened EE; 77.4±26µm), in addition to an increase in wedge-shaped subepithelial tissue. Patients with CIN had a mean thickened EE (262.5±124µm) and strongly hyperreflective, with abrupt transition between normal and pathological epithelium. Analysis of EE between subjects with pterygium and CIN revealed statistically significant differences (p<0.002). ROC curve revealed a 100% sensitivity and specificity of OCT-SA in differentiation between CIN and pterygium, using 141µm as cutoff point of EE. CONCLUSION: AS-OCT is a useful tool for the differentiation between pterygium and CIN able to provide typical morphological characteristics. An EE greater than 141µm in AS-OCT suggests a sensitivity and specificity of 100% for the diagnosis of CIN.

Caracterización epidemiológica de la neoplasia intraepitelial de la conjuntiva en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer" / Epidemiological characterization of conjunctival intraepithelial neoplasia in "Ramón Pando Ferrer" Cuban Institute of Ophtalmology

OBJETIVO: identificar el patrón epidemiológico de la neoplasia intraepitelial de la conjuntiva en el Instituto Cubano de Oftalmología «Ramón Pando Ferrer¼ (2005-2010). MÉTODOS: se realizó un estudio descriptivo en 106 pacientes con neoplasia intraepitelial unilateral según edad, sexo, enfermedad ocular asociada y años de diagnóstico. Se calcularon porcentajes, tasa de incidencia y prevalencia proporcional y se estimó la tendencia por método gráfico. RESULTADOS: el 59,4 % perteneció al sexo femenino (n = 63); el 53,8 % (n = 57) se encontró en edades entre 30 y 39 años, seguido por ³ 60 años con 33 % (n = 35); el 18,9 % (n = 20) presentó enfermedad ocular asociada, donde el 60 % (n = 12) correspondió al pterigium. Hubo entre 34 % (n = 36), 31, 1 % (n = 33) y 30,2 % (n = 32) con NIC I, NIC II y NIC III respectivamente, y el 4,7 % (n = 5) con carcinoma in situ. La incidencia en el 2009 alcanzó 3,1 % (n = 34) y 85,8 % de prevalencia (n = 91), con tendencia lineal al incremento. CONCLUSIONES: se manifiesta tendencia al incremento de la enfermedad; por eso merece atención el estudio de los factores de riesgo como enfoque preventivo para reducir este comportamiento, si se parte del aumento de la expectativa de vida de la población cubana con tendencia al envejecimiento, pues la neoplasia intraepitelial de la conjuntiva es característica de personas en edad avanzada.

OBJECTIVE: to identify the epidemiological pattern of intraepithelial neoplasia of the conjunctiva in the «Ramón Pando Ferrer¼ 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.
