Impression cytology of ocular surface in xeroderma pigmentosum.

PURPOSE: To describe cellular alterations detected by impression cytology of the ocular surface in patients with xeroderma pigmentosum. The secondary objective was to assess the reliability of impression cytology in diagnosing ocular surface squamous neoplasia. METHODS: Patients with xeroderma pigmentosum underwent a single-day complete ophthalmological examination and impression cytology for ocular surface evaluation using 13 mm diameter mixed cellulose esters membrane filters and combined staining with Periodic Acid Schiff, Hematoxylin and Eosin, and Papanicolaou stains followed by microscopic analysis. The cytological findings were correlated with the clinical diagnosis. The impression cytology findings at baseline and one-year follow-up were correlated with the clinical course (no tumor, treated tumor, residual tumor recurrent tumor, new tumor). RESULTS: Of the 42 patients examined, impression cytology was performed in 62 eyes of 34 participants (65% females). The mean age of patients was 29.6 ± 17 years (range 7-62). Fifteen eyes had a clinical diagnosis of ocular surface squamous neoplasia. Impression cytology showed goblet cells (47, 75%), inflammatory cells (12, 19%), keratinization (5, 8%), and squamous metaplasia (30, 48%). Impression cytology was positive for atypical cells in 18 patients (12 with and 6 without ocular surface squamous neoplasia). The sensitivity, specificity, positive predictive value, and negative predictive value of impression cytology (at baseline) for diagnosis of ocular surface squamous neoplasia were 80%, 87%, 67%, and 93%, respectively, using clinical diagnosis of ocular surface squamous neoplasia as the reference standard. CONCLUSION: Impression cytology has a moderate positive predictive value for the diagnosis of ocular surface squamous neoplasia in patients with xeroderma pigmentosum. However, the lack of detection of atypical cells on impression cytology has a high negative predictive value for ocular surface squamous neoplasia. Integration of impression cytology in the long-term management of high-risk patients, such as patients with xeroderma pigmentosum, can avoid unnecessary diagnostic biopsies.

Evaluation of Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum.

PURPOSE: To assess Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum and correlate with ocular surface changes. METHODS: This cross-sectional study evaluated patients with xeroderma pigmentosum. All patients underwent a comprehensive and standardized interview. The best-corrected visual acuity of each eye was determined. Detailed ophthalmic examination was conducted, including biomicroscopy examination of the ocular surface, Schirmer test type I, and meibography, and fundus examination was also performed when possible. Meibomian gland dysfunction was assessed by non-contact meibography using Oculus Keratograph® 5M (OCULUS Inc., Arlington, WA, USA). Saliva samples were collected using the Oragene DNA Self-collection kit (DNA Genotek Inc., Ottawa, Canada), and DNA was extracted as recommended by the manufacturer. Factors associated with abnormal meiboscores were assessed using generalized estimating equation models. RESULTS: A total of 42 participants were enrolled, and 27 patients underwent meibography. The meiboscore was abnormal in the upper eyelid in 8 (29.6%) patients and in the lower eyelid in 17 (62.9%). The likelihood of having abnormal meiboscores in the lower eyelid was 16.3 times greater than that in the upper eyelid. In the final multivariate model, age (p=0.001), mutation profile (p=0.006), and presence of ocular surface malignant tumor (OSMT) (p=0.014) remained significant for abnormal meiboscores. For a 1-year increase in age, the likelihood of abnormal meiboscores increased by 12%. Eyes with OSMT were 58.8 times more likely to have abnormal meiboscores than eyes without ocular surface malignant tumor. CONCLUSION: In the final model, age, xeroderma pigmentosum profile, previous cancer, and clinical alterations on the eyelid correlated with a meiboscore of ≥2. Meibomian gland dysfunction was common in patients with xeroderma pigmentosum, mainly in the lower eyelid. The severity of Meibomian gland dysfunction increases with age and is associated with severe eyelid changes.

Perfil epidemiológico das aplicações intravítreas de Ranibizumab / Epidemiological profile of Ranibizumab intravitreal applications

Resumo Objetivo: O objetivo desse trabalho é avaliar o perfil de aplicações intravítreas do Ranibizumab em uma população de adultos atendidos no Instituto Benjamin Constant, no ano de 2015, levando em consideração o efeito sobre a acuidade visual e a espessura macular após tratamento. O objetivo secundário é apresentar as principais indicações desse tipo tratamento no serviço de olhos acima citado. Métodos: Foi realizado um estudo retrospectivo seccional, em indivíduos acima de 20 anos entre os meses de março a agosto de 2015, para analisar a acuidade visual e espessura foveal pré e pós tratamento. A dose do anti-VEGF utilizada foi de 0,05ml por aplicação com intervalo de quatro semanas entre elas. A aferição da acuidade visual assim como o OCT pós tratamento foram realizados em torno de trinta dias após a última aplicação. As análises estatísticas foram feitas com uso do software SPSS versão 21 e o nível de significância estatística foi de 95% com um valor de p <0,05. Resultado: O estudo mostrou que a principal afecção relacionada a esse tratamento foi a retinopatia diabética não proliferativa associada ao edema macular (32,8%). Após o tratamento indicado com Ranibizumab, houve uma melhora da acuidade visual média de 0,70 para 0,59 (logMAR) e uma regressão da espessura macular, visto no OCT, de 408,1µm para 337,2 µm (valor de p <0,05). Conclusão: Pode-se concluir portanto, que o tratamento com Ranibizumab na população estudada contribuiu para uma melhor qualidade de vida dos pacientes, pois a maioria dele apresentou uma melhora estatisticamente significativa na acuidade visual após as aplicações.

Abstract The objective of this work is to evaluate the profile of intravitreal applications of Ranibizumab in a population of adults attended at the Benjamin Constant Institute in the year of 2015, taking into account the effect on visual acuity and macular thickness after the treatment. The secondary objective is to present the main indications of this type of treatment in the eye care mentioned above. A retrospective cross-sectional study was performed in individuals over 20 years of age between March and August of 2015 to analyze visual acuity and foveal thickness before and after treatment. The dose of anti-VEGF used was 0.05 ml per application with an interval of four weeks between them. Visual acuity assessment as well as OCT post treatment were performed around 30 days after the last application. Statistical analyses were performed using SPSS software version 21 and the level of statistical significance was of 95% with a value of p <0.05. The study showed that the main condition related to this treatment was non-proliferative diabetic retinopathy associated with macular edema (32.8%). After treatment indicated with Ranibizumab, there was an improvement in the average visual acuity from 0.70 to 0.59 (logMAR) and a regression of the macular thickness, seen in the OCT, from 408.1μm to 337.2μm (p < 0.05). It can be concluded, therefore, that treatment with Ranibizumab in the studied population contributed to a better quality of life of the patients, since most of them presented a statistically significant improvement in the visual acuity after the applications.
