Non-Leber type optic atrophy with early-onset OPA2 Optic atrophy type 2 Prevalence: Inheritance: X-linked recessive Age of onset: Childhood ICD-10: H47.2 OMIM: 311050 UMLS: C1839576 MeSH: - GARD: 10199 MedDRA: - The documents contained in this web site are presented [orpha.net]
A standard nonlinear click stimulus of 80 µs duration was presented at a repetition rate of 50 Hz and an intensity of 80 ( 3) dB SPL. [molvis.org]
Adrenal insufficiency, sepsis, and dehydration may, however, also present with similar laboratory findings. Ketosis with hyperglycemia is present in diabetic ketoacidosis. [mrineonatalbrain.com]
Patients with retinal telangiectasia may present with retinopathy. In younger patients this is referred to as Coats disease. [neuroweb.us]

Slurred Speech
All affected males have evidence of damage to the optic nerve and some have other neurologic signs such as tremor, slurred speech, and unsteadiness but these are usually mild symptoms. Mental retardation has been noted in a few patients. [disorders.eyes.arizona.edu]
Workup
This workup should include a Westergren erythrocyte sedimentation rate (ESR) in conjunction with a C-reactive protein test. 15-17 Neither ESR nor CRP is specific for GCA, but both can indicate acute inflammatory activity. [reviewofoptometry.com]

Prognosis
Diagnosis and Prognosis: The diagnosis is usually made by an ophthalmologist or sometimes by a neurologist. The prognosis is highly variable but once the optic nerve is damaged, the vision loss is not reversible. [disorders.eyes.arizona.edu]

(See 'Prognosis' above and 'Treatment' above.) SCA3, also known as Machado-Joseph disease, is the most common type of SCA (table 1). SCA types 9 through 36 are rare and less well characterized. (See 'Classification of SCA' above.) [es.slideshare.net]
[…] syndrome clinically and radiologically indistinguishable from multiple sclerosis, but whether the concurrence of these events exceeds the incidence expected by chance alone remains unresolved, particularly as an underlying LHON mutation may worsen the prognosis [slideplayer.com]
With time, the nerve becomes atrophic as the edema and hemorrhages resolve, and the visual prognosis remains very poor. In measurable eyes, altitudinal or central visual field defects are common. [reviewofoptometry.com]
