Furthermore, much of the research suggests that it is reliable, reproducible, not only an accurate means of diagnosing Thyroid Associated Orbitopathy (TAO) pathology and predicting its clinical course, but as a way to follow the course of the disease and the response to treatment as well...
Peripheral facial paralysis is a diagnostic challenge. Acute facial palsies are mostly “idiopathic” (Bell’s palsy) but it is a diagnosis of exclusion, and therefore cases of acute, acquired, isolated peripheral facial paralysis should be investigated thoroughly. Comprehensive efforts should be made to diagnose the cause, because some percentages of the patients referred with a diagnosis of Bell’s palsy were found to have a treatable, progressive, or life-threatening lesion.
Ultrasonography contains a wide selection of clinical indications. For instance, when examining a patient with ocular discomfort or pain, clinicians will use ultrasound to ensure a diagnosis of inflammation, orbital myositis, or dacryoadenitis. Imaging is often used to identify retrobulbar tissue, as well as the extraocular muscles, in patients with symptoms and suspected soft tissue enlargement secondary to Graves’ disease.

Nitric Oxide (NO) is a well known endogenous gasotransmitter with profound effects on mammalian physiology and also possesses major therapeutic implications. Despite the known toxicity of this molecule when present above the optimal concentration, plays key signaling and regulatory role in human life processes. From the literature survey it is evident that NO bears potential role almost in every system of human body. Among these systems nervous system has also been found linked with this molecule.
The human eye, composed of specialized tissues, has unique functions to admit or receive certain wavelengths of electromagnetic radiation. In order to integrate information from the entire visual field, visible light is collected and focused by the spherical lens onto retinal neurons. Excessive light exposure, however, not only mediates photoreceptor activation but also induces photodamage effects.
A 71 year old man presented with a history of cataract surgery in both eyes and gradual diminution of vision post surgery in right eye (RE) since 3 years.
