- Anemia
She had a history of anemia, hypertension, and chronic renal disease secondary to congenital renal hypoplasia for which she underwent successful kidney transplant. The participant provided written, informed consent. [frontiersin.org]

- Hypertension

Eyes
- Retinal Pigmentation
Outer retinal length, defined as the distance between the inner segment (IS)/outer segment (OS) and retinal pigment epithelium (RPE) bands in OCT images, was measured using both commercial OCT and the custom AO-OCT at the same retinal locations where [frontiersin.org]
Skin
- Macula
(C) OCT of the macula (dashed line in A) showed irregularity of the IS/OS band. See Figure 5 for additional detail. [frontiersin.org]
Anomaloscopy revealed matching ranges within normal limits, indicating the presence of long and middle wave cones of normal spectral sensitivity at the macula, while the absence of pseudoprotanomaly suggests that photopigment is present at normal optical [ncbi.nlm.nih.gov]
Neurologic
- Nystagmus
There was no nystagmus. Electrophysiological testing provided evidence of retinal dysfunction predominantly confined to the cone system. [ncbi.nlm.nih.gov]
The participant had no nystagmus and her anterior segment examination was only positive for age-appropriate nuclear sclerotic and cortical cataracts. [frontiersin.org]

Trichostrongylus capricola Trichostrongylus colubriformis Trichostrongylus longispicularis Trichostrongylus tenuis Trichostrongylus vitrinus trichothecene mycotoxin trichothecenes Trichothecium trichothiodystrophy trichothiodystrophy, photosensitive trichotillomania [medical-dictionary.thefreedictionary.com]
- Confusion
Vermillion, green, and blue lines indicate protan, deutan, and tritan confusion lines, respectively. (C) A magnified view of the area inside the dashed rectangle from (B). [frontiersin.org]
Treatment
Management and treatment There is no effective treatment for the underlying retinal disorder. Patients should be provided with accurate visual aids: eyeglasses that can be tinted if photophobia is a prominent feature. [orpha.net]
Prognosis
Prognosis Although few patients with this disorder have been followed up long term, it appears that the prognosis is good as the disorder is usually non-progressive. [orpha.net]
Etiology
Etiology The causative gene has not been identified. [orpha.net]
Epidemiology
Summary Epidemiology The syndrome is very rare with less than 15 cases reported in the literature so far. Clinical description Individuals with this disorder have reduced visual acuity from a young age and usually have a mild degree of photophobia. [orpha.net]
