Abstract
Clinical case

A 27-year-old woman with a history of nyctalopia and constriction of visual field of the right eye. The ophthalmological examination showed a visual field and electroretinogram that were compatible with unilateral retinitis pigmentosa (RP). After a one year follow-up, the unilateral condition remained.

Discussion

Unilateral retinitis pigmentosa is a rare condition, with a frequency between 0.2% and 5% of the RP. It mainly affects women and older age groups than bilateral RP. For a definitive diagnosis, it is necessary to have a funduscopy and electroretinogram (ERG) altered unilaterally, and exclude infectious, inflammatory, and vascular causes.

Resumen
Caso clínico

Mujer de 27 años con historia de nictalopía y constricción de campo visual del ojo derecho. El examen oftalmológico, campo visual y electrorretinograma (ERG) fueron compatibles con una retinitis pigmentosa (RP) unilateral. Al seguimiento de un año, permanecía la afección unilateral.

Discusión

La RP unilateral es un trastorno infrecuente, con una frecuencia entre el 0,2-5% de las RP. Afecta principalmente a mujeres, y en edades más avanzadas que las bilaterales. Para dar un diagnóstico definitivo tiene que haber un fondo de ojo y ERG alterados unilateralmente, y excluir causas infecciosas, inflamatorias y vasculares.
