Vision problems in people over 50 years old in Peru: A population-based study

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 lower frequency of LDVP and SDVP. Conclusion: The history of cataract and vision problems in the studied population vary according to sociodemographic and geographic characteristics. The identification of factors related to these events of interest allows us to propose better interventions to control these problems

Recurrent vitreous hemorrhage secondary to retinal vessel avulsion

Spontaneous vitreous hemorrhage is a rare entity, present in 7 out of 100,000 inhabitants. It is associated with different pathologies; however, it is rarely reported to be caused by retinal vessel avulsion syndrome. In the present manuscript, we report a case of avulsion of retinal vessels associated with recurrent vitreous hemorrhage managed, at first, by photocoagulation, but due to the several recurrence of bleeding, the patient went into surgical management

Primary orbital cystic tumor: a case of hydatidosis in a child

Primary orbital cystic tumors caused by Echinococcus granulosus are rare. As this parasite is endemic in Peru, we report the case of a 10-year-old girl from a rural area of Huancavelica, who presented with progressive and irreducible axial proptosis of the right eye and loss of vision. Orbital tomographic images demonstrated a tumor mass with a cystic appearance. Serologic tests were negative. The patient underwent surgical resection, and histopathologic analysis revealed anhistic membranes, corresponding to hydatid cysts. During one year of follow-up, no evidence of local or systemic recurrence was observed. In conclusion, orbital hydatidosis should be considered in the differential diagnosis of a cystic orbital tumor in pediatric patients, especially if the patient is from an endemic area

Conjunctival squamous cell carcinoma: Prognostic factors for the recurrence and metastasis and clinicopathological characteristics at an oncological hospital in Peru

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, node, metastases (TNM), stage T3 was the most frequent (31.3%). The most performed initial treatment was orbital exenteration (38.6%). The proportion of recurrence was 6.8% and 8.0% for metastasis. The annual survival rate was 7% and the annual metastasis rate was 6%; for recurrence after 5 years, the survival rate was 11% and the metastasis rate was 14%. No prognostic factor evaluated was significant. Conclusion This is the most extensive patient study in Latin America with CSCC, with a high proportion of advanced histopathological grade, TNM stages, and radical treatments such as exenteration. Recurrence rates on average are similar to other reported studies, and it describes the rates of metastasis that have been poorly described in the literature.Revisión por pare
