Clinical Subtypes of Cone-Rod Dystrophy
Archives of Ophthalmology, 1993To determine possible distinct phenotypic subtypes of cone-rod dystrophy.Thirty-three patients with cone-rod dystrophy (from 25 families) were assessed prospectively on electroretinography, visual field testing, psychophysical threshold profiles, and fundus features.

Spondylometaphyseal dysplasia with cone‐rod dystrophy
American Journal of Medical Genetics Part A, 2004AbstractThe co‐occurrence of ophthalmologic abnormality and intrinsic skeletal dysplasia is uncommon. We describe eight instances of a unique form of spondylometaphyseal dysplasia (SMD) associated with cone‐rod dystrophy (although documentation is insufficient to be certain of that diagnosis in some).

Archives of Ophthalmology, 1989
Three patterns of visual dysfunction were identified in patients with autosomal recessive or simplex cone-rod dystrophy using rod and cone electroretinography and light- and dark-adapted static threshold perimetry. In the first pattern, there was a central rod and cone scotoma with eccentric fixation, mild peripheral retinal dysfunction equally ...

Progressive Cone Dystrophy and Cone-Rod Dystrophy
A heterogenous group of diseases, progressive cone dystrophy usually begins in the mid-teenage years or later in life. The estimated prevalence is 1 in 30,000-40,000 individuals. Patients usually present with decreased central vision and a color vision deficit; the visual loss is progressive and often accompanied by day blindness (hemeralopia) and ...Benjamin Kuang-Chien, Chiang +3 more

Keratoconus Associated With Cone-Rod Dystrophy
Cornea, 2002A 31-year-old man with bilateral keratoconus associated with apical corneal scarring underwent uneventful penetrating keratoplasty in his left eye. Postoperatively his best-corrected visual acuity did not improve beyond 20/120. Examination of the fundus revealed features suggestive of bull's eye maculopathy.

Temporal aspects of the electroretinogram in cone-rod dystrophy
Documenta Ophthalmologica, 1985Twelve patients with cone-rod dystrophy were studied in terms of the temporal aspects of electroretinography (ERG). The peak time of scotopic b-wave was within normal limits in all patients, while the amplitude was reduced in nine patients. The normal peak time of the scotopic-b wave may help explain rod involvement with normal or only slightly ...

Cone-rod dystrophy in Danon disease
Graefe's Archive for Clinical and Experimental Ophthalmology, 2012In this issue, Thiadens and colleagues report ophthalmoscopic findings of macular disruption and physiologic findings of cone-rod dystrophy in two of four cousins from a family with Danon disease, a rare X-linked disorder characterized by muscle weakness, cardiomyopathy, and mental impairment, which has been mapped to mutations in the ...

Rod increment thresholds in cone-rod dystrophy
Applied Optics, 1989Rod system increment threshold functions (ITFs) were studied in patients with cone-rod dystrophy (CRD). Rod thresholds (I(t)) for a 104-min, 500-nm test stimulus (TS), superimposed on an 11 degrees long wavelength background (luminance I(b)), were measured in eleven CRD patients and fourteen normal subjects.

Progressive cone–rod dystrophy
Clinical Eye and Vision Care, 1999Abstract Inherited macular dystrophies present with varying clinical signs. They possess significant overlap with other inherited retinal dystrophies and with several acquired retinal degenerations. A classification system for diagnostic purposes is crucial.
