Treatment Guidelines There is no local (retinal) treatment for primary optic atrophy so no referral to a retinal specialist is warranted. The key to proper treatment is determining the etiology of the optic atrophy. [decisionmakerplus.net]

One of the reasons for pessimism is that there is too often an excessive delay in starting treatment and that, as a result, optic atrophy may progress to blindness before adequate treatment is instituted. [nejm.org]

Treatment depends on which disorder that you have. With some optic nerve disorders, you may get your vision back. With others, there is no treatment, or treatment may only prevent further vision loss. [icdlist.com]

Until recently, there was no treatment indicated for LHON. [santhera.com]

However, after established optic neuropathy and visual loss there is little chance, if any, for visual recovery and no definitive treatment exist for treatment in these cases. [clinicaltrials.gov]

It was found that the prognosis for useful vision is in general favorable in this group of cases. [pediatrics.aappublications.org]

Unfortunately, a prompt diagnosis is of extreme importance, since the sooner an appropriate treatment is initiated, the better the prognosis and the less probability of permanent visual damage. [frontiersin.org]

Visual prognosis following optic neuropathy is generally poor. Renal biopsy provided a clue for the diagnosis in the absence of clinical findings other than ocular involvement in these patients. [japi.org]

In 27 % of the cases no cause could be found while in the rest of 73% cases definite etiological factor was present. [ijo.in]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

Etiology and Pathophysiology Genetic etiologies usually involve defects in mitochondrial function. Exposure of retinal nerve cells to light normally results in the generation of free radical species. [unboundmedicine.com]

Etiologic classification Regardless of etiology, optic atrophy is associated with variable degrees of visual dysfunction, which may be detected by one or all of the optic nerve function tests (see Other Tests). [thehealthscience.com]

Epidemiology Acquired ONA is more common than hereditary and congenital ONA and tends to occur later in life: Glaucoma, ischemic optic neuropathy (older), optic neuritis (younger), compressive (any age), and toxic/nutritional are leading causes in adults [unboundmedicine.com]

Pathophysiology The optic nerve comprises approximately 1.2 million axons that originate at the ganglion cell layer of the retina. [thehealthscience.com]

Traumatic optic neuropathy The exact pathophysiology of traumatic optic neuropathy is poorly understood, although optic nerve avulsion and transection, optic nerve sheath hematoma, and optic nerve impingement from a penetrating foreign body or bony fragment [emedicine.medscape.com]

Pathophysiology There is a loss of axons and shrinkage of myelin, leading to widening of the optic cup. Presentation [ 1 ] This depends on the causative condition. Optic disc atrophy in isolation results in the following symptoms and signs. [patient.info]

Etiology and Pathophysiology Genetic etiologies usually involve defects in mitochondrial function. Exposure of retinal nerve cells to light normally results in the generation of free radical species. [unboundmedicine.com]

The pathophysiology of NAION is unknown, but it is related to poor circulation in the optic nerve head. [en.wikipedia.org]

They have to be also aware of the preventive measures and precautions to be taken, which include: Avoidance of multiple sex partners Practice of safe sex (use of condoms that prevent entry of the syphilis bacteria) Excessive craving for drugs and alcohol [dovemed.com]

Primary prevention (removal of the process causing the damage) is the goal to prevent loss of axons and optic atrophy (neuropathy). [eyewiki.aao.org]

For example, early diagnosis and aggressive treatment can prevent further damage in patients with compressive and toxic neuropathies. Intravenous steroids are helpful in some cases of optic neuritis or anterior ischemic optic neuropathy. [decisionmakerplus.net]
