Unilateral Visual Impairment: Causes & Reasons

Possible Causes for Unilateral Visual Impairment

 Painless unilateral visual impairment, usually gradually worsening over about a week.  ○ Papillitis associated with peripapillary and macular oedema.  ○ A macular star [slideshare.net]

It is also important to exclude possible reversible causes of visual loss that require immediate attention, for example a retrobulbar haemorrhage. [cochranelibrary.com]

Although usually straightforward the assessment of TON can sometimes prove difficult in the setting of severe trauma when the patient's level of consciousness is impaired. [cochranelibrary.com]

Toxocariasis

What is the retina? The retina is the thin layer of light-sensing nerve cells lining the inside back of your eye.

Mucocele of the Sphenoid Sinus

Mucocele of the Sphenoid Sinus Presenting With Unilateral Visual Impairment A Case Presentation Author: Dr. Caner Sahin. Attending Otolaryngologist. [waent.org]

Because of its close proximity to the sphenoid sinus, the optic nerve may be compressed and visual impairment may result. [ncbi.nlm.nih.gov]

In such cases, the optic nerve, because of its close proximity to the sphenoid sinus, is at risk, and pressure exerted by the mucocele may result in visual impairment. [ncbi.nlm.nih.gov]

Congenital Toxoplasmosis

One child had unilateral severe visual impairment and CNS involvement. The incidence of congenital toxoplasmosis was less than 1:10,000. [ncbi.nlm.nih.gov]

Seven of them had macular lesions that caused unilateral visual impairment, although none of the macular lesions progressed. [nejm.org]

Ocular Toxoplasmosis

Significant differences were found for size of active lesions, unilateral macular involvement, unilateral visual impairment, vitreous inflammation, synechiae, and vasculitis [ncbi.nlm.nih.gov]
