A man, 58, arrived complaining of BOV for both near and distance vision in both eyes, with a 6/9 BCVA in each eye. For a year, the patient had been taking medication for both diabetes and hypertension. In both eyes, the dilated ophthalmoscopic retina revealed waxy disc pallor paired with bony spicules in the mid-periphery. The patient was prescribed spectacles and given counseling regarding the nature of the illness.

Ultra-wide-field pseudocolor image of the right eye of an 39-year-old female with Retinitis Pigmentosa. She had slightly atypical appearance due to asymmetry: sectoral atrophy in left eye, compared to 360 degree bone spicule formation in right eye. Ddx: Pigmentary degeneration vs infection vs X-linked RP carrier due to asymmetry. Recommended genetic testing through My Retina Tracker, as well as visual field and ERG testing. Patient's vision was sc20/100 PH 20/70 in the right eye and sc20/80 PH 20/40 in the left.
