ABSTRACT

To evaluate the effect of chlorogenic acid supplementation in patients with retinitis pigmentosa, we evaluated objective change in visual function with multifocal electroretinography, along with visual acuity, visual field, standard electroretinography, and contrast sensitivity. Eighteen patients diagnosed with retinitis pigmentosa were enrolled in this prospective, non-comparative, single-arm study. Multifocal electroretinography, best-corrected visual acuity in Early Treatment Diabetic Retinopathy Study letters, total point score on visual field examination with Humphrey Field Analyzer II, electroretinography, and contrast sensitivity were measured and repeated after 3 months supplementation with chlorogenic acid. The amplitude of ring 5 was significantly higher on multifocal electroretinography after 3 months of chlorogenic acid supplementation (7.2 +/- 9.5 vs 8.3 +/- 10.8 nV/deg2, mean +/- standard deviation, P = 0.022). There were no significant changes in the best-corrected visual acuity, total point score on Humphrey Field Analyzer, 30 Hz flicker amplitude on standard electroretinography, or contrast sensitivity. Chlorogenic acid may have a beneficial effect on the peripheral area at the margins of retinal degeneration, and should be considered as an anti-oxidant for the management of retinitis pigmentosa.

ABSTRACT

Retinose pigmentar indica um grupo heterogêneo de doenças genéticas oculares raras em que tanto bastonetes quanto cones estão danificados, levando a um prognóstico ruim com eventual perda da visão. Descrevemos o caso de mulher de 22 anos com edema macular recorrente devido à retinose pigmentar. Obteve-se sucesso terapêutico após o tratamento com o implante intravítreo de dexamentasona (Ozurdex®, Allergan,USA).


Retinitis pigmentosa denotes a heterogeneous group of rare genetic diseases in which both rods and cones eye are damaged. It is a disease of poor prognosis. We describe the case of a 22 years old woman successfully treated with intravitreal implant of dexamentasone (OZURDEX®, Allergan, USA) for the treatment of macular edema due to retinitis pigmentosa.

ABSTRACT

OBJETIVO: Profundizar en los efectos de la ozonoterapia y electroestimulación sobre la función visual de los pacientes que padecen retinosis pigmentaria. MÉTODOS: Se estudiaron 186 pacientes portadores de retinosis pigmentaria. Fueron agrupados atendiendo a los estadios clínicos de la clasificación cubana (4 grupos). Se aplicó ozonoterapia y electroestimulación, una sesión diaria de cada una durante 14 días. Se realizó un examen oftalmológico antes y después del tratamiento, para la agudeza visual se empleó cartilla de Snellen y para el campo visual cinético tipo Goldman. Los datos estadísticos se analizaron y compararon usando la prueba t de Student. Se consideró p < 0,05 como significación estadística. RESULTADOS: En los 57 pacientes agrupados en el estadio 1, la agudeza visual con corrección se mantuvo igual. Se observaron modificaciones significativas del campo visual en 16 pacientes. En los 66 pacientes agrupados en el estadio 2, la agudeza visual con corrección se mantuvo igual en 48 pacientes con modificaciones significativas del campo visual en 29 pacientes. En el estadio 3 se agruparon 49 pacientes donde la agudeza visual con corrección se mantuvo igual en 38 pacientes, observando modificaciones muy significativas del campo visual en 27 pacientes. CONCLUSIÓN: En la estrategia multiterapéutica cubana para el tratamiento de la retinosis pigmentaria, las aplicaciones cíclicas anuales de ozonoterapia y electroestimulación son imprescindibles para mantener un control de la enfermedad


OBJECTIVE: To analyze in depth the effects of ozone therapy and electrical stimulation on the visual function of patients suffering pigmentary retinitis. METHODS: One hundred and eighty six patients carrying pigmentary retinitis were studied. They were grouped according to the clinical staging of the Cuban classification (4 groups). Ozone therapy and electrical stimulations were applied daily for 14 days. An ophthalmologic test before and after the treatment was performed; Snellen´s charter for visual acuity and Goldman-type kinetic visual field. Statistical data were analyzed and compared using Student´s t test. The statistical significance was set at p<0,05. RESULTS: The corrected visual acuity remained the same in the 57 patients grouped in staging 1. Significant changes were observed in the visual field of 16 patients. Regarding the 66 patients in staging 2, corrected visual acuity remained the same in 48 whereas 29 patients experienced significant changes in their visual field. Forty nine patients were included in the staging 3 where corrected visual acuity kept the same value in 38 patients, but very significant changes in the visual field of 27 patients were observed. CONCLUSION: In the Cuban multitherapeutical strategy for the treatment of pigmentary retinitis, the annual cyclic use of ozone therapy and electrical stimulation is essential to keep control over the disease

ABSTRACT

Se realizó un estudio descriptivo y prospectivo de un universo de 73 pacientes con retinosis pigmentaria, atendidos en el Centro Provincial de Retinosis Pigmentaria de Santiago de Cuba desde enero hasta mayo de 1996, con el objetivo de destacar la labor de enfermería en la aplicación de la ozonoterapia. En la retinosos pigmentaria, las vías de aplicación de este gas pueden ser variadas: autohemoterapia, intramuscular e insuflación rectal. La información obtenida se procesó de forma manual y se usó el porcentaje como medida de resumen. Entre los principales resultados figuran el predominio de las edades jóvenes y del sexo masculino; el mayor número de pacientes se encontraban en los estadios II y III de la enfermedad y la vía de administración del ozono más empleada fue la rectal. Este último aspecto demuestra la importancia de la relación enfermera-paciente, la cual contribuyó de manera decisiva a la aceptación de la vía rectal, que antes era rechazada por gran número de pacientes
