Alteraciones retinianas detectadas por screening con cámara retinal no midriática y derivación a oftalmología en una población de alto riesgo cardiovascular / Retinal alterations detected by non-mydriatic retinal camera screening and referral to ophthalmology in a population with high cardiovascular risk

Objetivo Describir las principales alteraciones retinianas detectadas por screening con cámara retinal no midriática y evaluar los factores relacionados con la derivación a oftalmología en una población de alto riesgo cardiovascular en Palmira, Colombia. Materiales y métodos Estudio observacional de tipo transversal, con 11.983 registros fotográficos de pacientes con hipertensión y diabetes mellitus del programa de enfermedades crónicas de Gesencro S.A.S. entre 2018 y 2020. Se evaluaron con regresión logística los factores de riesgo relacionados con la derivación a oftalmología y se obtuvieron los odds ratios (OR) crudos y ajustados. Resultados Se analizaron 11.880 registros; la edad media fue de 67,7±12años, y el 69,5% fueron mujeres. Entre las alteraciones retinianas se encontraron pacientes con retinopatía diabética clasificada como más que leve (10%) y gradoI de retinopatía hipertensiva (54,9% ojo derecho, 51,9% ojo izquierdo). También se identificó edema macular (15%). Solo 2.069 (17,4%) pacientes requirieron derivación a oftalmología; el 81,3% requirieron control a 1año y el 1,3% a los 6meses. En el análisis multivariado los factores de riesgo que se relacionaron con la probabilidad para ser derivados fueron: el género masculino, la edad mayor o igual a 60años, la hemoglobina glucosilada (HbA1c) fuera de metas, la enfermedad renal crónica avanzada y la razón microalbúmina-creatinina moderada a severamente elevada. Conclusión Este estudio permitió determinar la importancia que tiene el screening con cámara retinal no midriática en pacientes de alto riesgo cardiovascular para detectar alteraciones retinianas y evaluar factores de riesgo asociados con derivación a oftalmología. El documentar tempranamente el compromiso ocular en estos pacientes podría prevenir y evitar la discapacidad visual y la ceguera (AU)

Objective To describe the main retinal alterations detected by non-mydriatic retinal camera screening and to evaluate factors related to referral to ophthalmology in a population at high cardiovascular risk in Palmira, Colombia. Materials and methods Cross-sectional observational study, which included 11,983 photographic imaging records of patients with hypertension and diabetes mellitus from Gesencro's S.A.S. comprehensive chronic disease care program between 2018 and 2020. Risk factors associated to referral to ophthalmology were evaluated with logistic regression, and crude and adjusted ORs (odds ratios) were obtained. Results A total of 11,880 records were analyzed; 67.7±12years old, and 69.5% were women. Among the retinal alterations were patients with diabetic retinopathy classified as more than mild in 10% and gradeI hypertensive retinopathy in 54.9% right eye, 51.9% left eye. Macular edema was also identified. Only 2069 patients (17.4%) required referral to ophthalmology, and for imaging control 82.6%. In the multivariate analysis, the risk factors associated with the probability of being referred were male gender, age 60years and older, glycosylated hemoglobin out-of-target, advanced chronic kidney disease and the microalbumin-to-creatinine ratio moderate to severely elevated. Conclusion This study makes it possible to determine the importance of screening with a non-mydriatic retinal camera in patients at high cardiovascular risk to detect retinal abnormalities and assess risk factors associated with referral to ophthalmology. Early documentation of ocular compromise in these patients could prevent and avoid visual impairment and blindness (AU)
