This is fundus picture of a 21 year old female patient who had come for refractive surgery consultation. Her best corrected vision in both eyes was 20/20. She had myopic astigmatism in both eyes. Fundus exam revealed presence of multiple yellowish white flecks spread throughout retina sparing macular area in both eyes. Her color vision was normal. Electroretinogram and electrooculogram were normal. She gave no history of night blindness. A diagnosis of Benign Familial Fleck Retina was made. She was also advised ocular exam of her parents and elder brother which was normal.

The left most column are control full field ERG responses from an individual with no known retinal pathology. In the second column is an example from a patient with autosomal recessive retinitis pigmentosa. This is an example of an intermediate case where rod function is extinguished but some cone function remains. In more advanced cases, full field ERG responses are typically extinguished to both scotopic and photopic stimuli. The third column is an example of congenital stationary night blindness (CSNB). While full field ERG responses can vary greatly depending on the specific subtype, this example of “complete CSNB” demonstrates extinguished rod pathway responses with the classic electronegative response for the scotopic 3.0 and 10.0 responses, consistent with bipolar cell dysfunction. Photopic cone responses are largely normal in this instance, but ”incomplete CSNB” can cause reduced photopic responses. In the final column, an example of full field ERG responses from a patient with achromatopsia. In achromatopsia, cone function is extinguished early in life, while rod pathway function is largely normal. ERG testing was completed using the Diagnosys ColorDome.

These are the fundus pics of a 28 year young male who presented with history of night blindness. Fundus examintaion revealed presence of Choroideremia. There is diffuse pigment clumping followed by atrophy of retinal pigment epithelium, photoreceptors and choriocapillaris with visible sclera and choroidal vessels in this condition. Atrophy progresses centripetally and the fovea is the last to become affected.

Fundus autofluorescence of the left eye in a 58 yo male with rod cone dystrophy. He presented with night blindness and peripheral vision loss since youth and recent decrease in central vision for the past 10 years. Notice multiple coin shaped hypoautofluorescent pacthes within central 20 degrees which are coalescing centrally. (fundus photo uploaded separately) He has one pathogenic variants of both CEP290 and PRPH2 genes.

Fundus photograph of the left eye in a 58 yo male with rod cone dystrophy. He presented with night blindness and peripheral vision loss since youth and recent decrease in central vision for the past 10 years. Notice waxy pallor of the nerve, severe arterial narrowing and chorioretinal atrophy mainly around the arcades as well as posterior pole along with RPE hyperplastic changes and atrophy. RPE atrophy in midperiphery has coin shaped appearance. FAF has characteristic appearance (uploaded separately) He has one pathogenic variants of both CEP290 and PRPH2 genes.

Montage wide field fundus photograph of the left eye of the same patient. 55-year-old male presented with late onset night blindness and peripheral vision loss for one year. Central vision is preserved at 20/25. ERG demonstrated extinguished rod function, and minimally diminished cone function. Waxy pallor of the optic nerve, arterial narrowing, and peripheral bony spicules are the classic triad of RP which are demonstrated in the photograph.

50-year-old male came in with complaint of daytime vision loss for a year and nighttime vision loss for more than 20 years, gradually increasing day by day. Fundus showed paving-stone like areas of atrophy of the RPE involving the macula which coalesces to form a characteristic scalloped border at the junction of normal and abnormal RPE. Gyrate atrophy is an autosomal recessive dystrophy caused by tenfold elevations of plasma ornithine, which is toxic to the RPE and choroid. Patients with gyrate atrophy have hyperpigmented fundi, with lobular loss of the RPE and choroid, normally sparing the fovea. The finding of generalized hyperpigmentation of the remaining RPE helps to clinically distinguish gyrate atrophy from choroideremia. Affected patients usually develop night blindness during the first decade of life and experience progressive loss of visual field and visual acuity later in the disease course. Early diagnosis is crucial because treatment in form of Arginine free diet and oral pyridoxine helps in slowing the progression of disease.
