Presentation
From these findings, a staging system for this subset of Stargardt disease presenting with central cone dysfunction was developed and presented herein. [ncbi.nlm.nih.gov]
The clinical phenotypes differed between the proband and her mother and were indistinguishable from other sporadic or RP1L1-unassociated OMD patients, suggesting that mutation-dependent clinical features may not be present. [sigmaaldrich.com]
Entire Body System
- Weakness
RESULTS: The FAF images showed unspecific weak foveal hyperfluorescence in 4 eyes of 2 patients; one showed a thin hyperfluorescence in the temporal fovea bilaterally and the other showed weak hyperfluorescence in the fovea bilaterally. [ncbi.nlm.nih.gov]
The disease is characterized by MUSCULAR ATROPHY; MUSCLE WEAKNESS; CONTRACTURE of the elbows; ACHILLES TENDON; and posterior cervical muscles; with or without cardiac features. [bioportfolio.com]
[…] neurological problem has, therefore, been ruled out, the disorder's reduced visual acuity without visible fundus abnormalities may be misdiagnosed as optic neuritis, dominant optic atrophy, amblyopia, or nonorganic visual disorder.[12] The combination of weak [en.wikipedia.org]
Lead is a relatively unreactive post-transition metal and its weak metallic character is illustrated by its amphoteric nature and tendency to form covalent bonds. Compounds of lead are found in the +2 oxidation state. [wikivisually.com]
- Asymptomatic
Clinical data of the four asymptomatic cases and three symptomatic patients in the same families were reviewed. The three asymptomatic cases did not have any visual symptoms in either eye, and one was unilaterally affected. [ncbi.nlm.nih.gov]
Clinical and tomographic results in the three asymptomatic relatives were normal. [ingentaconnect.com]
The clinically unaffected and asymptomatic family members did not agree for further evaluation with SD-OCT and mfERG. [ojoonline.org]
The complete penetrance autosomal dominant mode of inheritance is often challenged by a lack of parental genetic material, asymptomatic carrier relatives, and other mitigating factors. [molvis.org]

Eyes
- Visual Impairment
The degree of photoreceptor alterations was correlated with the severity of visual impairment. Clinical and tomographic results in the three asymptomatic relatives were normal. [ncbi.nlm.nih.gov]
Between the genetic disorders causing visual impairment, by affecting 1 person to 3000-4000, Inherited Retinal Dystrophies, Occult Macular Dystrophy and Age-related Macular Degeneration are the most diffuse. [research.unipd.it]
Discussion Occult macular dystrophy is a rare heritable cause of bilateral visual loss that typically presents in the fourth or fifth decades. The degree of visual impairment is quite variable, with acuities ranging from 20/20 to 20/400. [healio.com]
Many patients with IRDs present as sporadic cases without definitive family history of visual impairment, precluding the assessment of mode of inheritance. [molvis.org]
- Photophobia
Visual function and ophthalmoscopic and electroretinographic findings in a 56-year-old man suffering from gradually progressive photophobia and visual dysfunction were followed up over 4 years. [ncbi.nlm.nih.gov]
The diseases are progressive and characterized by difficulties in night vision, loss of peripheral vision and photophobia, until complete blindness. [research.unipd.it]
Clinically, CDS are characterised by presentation at birth/early infancy with visual loss and variable degrees of colour vision abnormalities, nystagmus and photophobia, These reflect the dysfunction of the foveally concentrated cone cells that constitute [goodhopeeyeclinic.org.uk]
- Visual Acuity Decreased
Loss of cone photoreceptor outer segments may be responsible for decreased visual acuity and foveal thinning in OMD. [healio.com]
- Photopsia
The patients usually discern a distinct loss of visual field with photopsias. The distinct loss of outer retinal response due to AZOOR is demonstrated in the Figure 6. [reviewofophthalmology.com]
Psychiatrical
- Suggestibility
Imaging tests were done to excluding expansive lesions and electrophysiological tests that suggested the diagnosis. [scienceopen.com]
Fundus autofluorescence imaging in our case of dominant autosomal OMD suggests a healthy and functional RPE. This examination of RPE should therefore be added to the work-up of suspected OMD. [ncbi.nlm.nih.gov]
The clinical phenotypes differed between the proband and her mother and were indistinguishable from other sporadic or RP1L1-unassociated OMD patients, suggesting that mutation-dependent clinical features may not be present. [sigmaaldrich.com]
A significant number of sporadic cases occur, however, which suggests new mutations are relatively common or that there is etiologic heterogeneity. [disorders.eyes.arizona.edu]

For example, OMD presents negative for a full-field ERG while retinitis pigmentosa presents abnormal.[13][14] Prognosis[edit] Since the abnormality is not in the eye lens, the disease is not correctable with eyeglasses. [en.wikipedia.org]
Etiology
Based on this data, Occult Macular Dystrophy may in fact represent more than one condition with multiple etiologies. Several etiologies are considered. [ncbi.nlm.nih.gov]
