Retinitis pigmentosa pigmentation pattern demonstrated with ultrawide fundus imaging using the scanning laser ophthalmoscope (Optomap; Optos PLC, Dunfermline, Scotland, United Kingdom).
Fellow eye of same patient as in the image above, again demonstrating a typical retinitis pigmentosa pigmentation pattern demonstrated with ultrawide fundus imaging using the scanning laser ophthalmoscope (Optomap; Optos PLC, Dunfermline, Scotland, United Kingdom).
Higher resolution image of typical bone spicule formation.
Cone dystrophy demonstrating typical central macular atrophy found in this condition.
Retinitis pigmentosa, rubella, a history of retinal detachment, and syphilis all may result in a hyperpigmented retinal pigment epithelium (RPE) with bone spicule appearance, restricted visual field and/or poor vision, and atrophic vessels.
Retinitis pigmentosa progresses over decades. Associated cataract also is relevant, as seen in this image.
Pigmentary changes are not always seen in retinitis pigmentosa but frequently are observed, as in this patient with Alström disease.
Genetic screening may be helpful in identifying patients who are at risk, in counseling, and in directing treatment as new knowledge is acquired. Some varieties of retinitis pigmentosa may have increased vulnerability to environmental hazards; for example, one might avoid light exposure in some rhodopsin mutations or sildenafil in phosphodiesterase mutations. Patients with retinitis pigmentosa may have other findings. This patient with Alström disease shows acanthosis.
