Objective: To evaluate the history of cataract and vision problems in people over 50 years of age in Peru. Methods: Secondary database analysis of the Demographic and Family Health Survey (ENDES) 2016. We included 7970 adults over 50 years of age. We evaluated the indicators of interest at the national and regional level. Likewise, we analyzed factors related to these events using a multivariate Poisson model. Results: 13.6% (95% CI: 12.8-14.3%) had a history of cataract, 20.4% (95%CI: 19.5-21.3%) had long-distance vision problems. (LDVP) and 29.4% (95%CI: 28.4-30.4%) of short-distance vision problems (SDVP). In the multivariate model, we observed that people with a history of high blood pressure, a history of diabetes, and older age groups were significantly more likely to report a history of cataracts and vision problems. We also observed that people with a better economic status had a...

Background/aims Conjunctival squamous cell carcinoma (CSCC) is the most frequent malignant tumour of the conjunctiva, with scarce recurrence and infrequent metastasis. The purpose of this study is to describe the clinical and pathological characteristics of this neoplasm and to identify the prognostic factors for recurrence and metastasis in a cancer hospital in Peru. Materials and method A longitudinal, retrospective study of 176 consecutive patients diagnosed with SCC of the conjunctiva. Sociodemographic and clinical characteristics were evaluated. In addition, Kaplan-Meier curves were performed, and Cox regression was used to determine prognostic factors for recurrence and metastasis over time. Result Only 12.5% presented tumour size ≤5 mm. The highest proportion according to the histopathological type was the well-differentiated infiltrative forms (40.9%), and according to tumour, ...

Objectives: Describe the images of the choroid by optical coherence tomography (OCT) spectral domain in healthy subjects and chorioretinal diseases. Materials and methods: Case series study. We evaluated 67 cases involving healthy ocular subjects and patients with chorioretinal diseases. The scans included a sweep of the retina and choroid at level of the macula conventionally, and other using enhanced depth imaging (EDI). The choroid thickness was measured from the outer edge of the retinal pigment epithelium to the internal scleral rim. Results: Of the 67 cases, 12 (17.4%) were healthy ocular subjects, 10 (14.5%) with central serous chorioretinopathy (CSC), 23 (33.4%) agerelated macular degeneration (AMD), 9 (13.0%) with myopia, 13 (18.8%) with polypoidal choroidal vasculopathy. There are differences in the quality of images with conventional OCT and those with EDI, allowing only to de...
