or mechanical etiologies that are present at birth (congenital) or acquired.2The severity of ptosis is classified as mild (1–2 mm), moderate (3–4 mm), and severe (>4 mm).1Treatment ofeyelid ptosisnecessitates an accurate diagnosis and is dependent on a comprehensive ocular history...
Ptosis is classified as congenital or acquired and has several etiologies that can be grouped into myogenic, aponeurotic, neurogenic, or mechanical disruptions (Table 3.7.1). It is critical to distinguish ptosis from pseudoptosis. Pseudoptosis resembles an inability to elevate the eyelid, and there...
The differential diagnosis of binocular vertical diplopia with ptosis can be organized broadly into neurogenic and myogenic etiologies. Neurogenic causes of ptosis and vertical diplopia include oculomotor nerve palsy and myasthenia gravis. While ...
In our young patient, occurrence of the ptosis during treatment, increase during new infusions of vincristine and exclusion of other aetiologies are forceful arguments to consider the role of vincristine in this side effect. The use of pyridoxine or pyridostigmine were suggested to treat vincristine-...
Open access provides opportunities for further open innovation to address the current limitations of the device, ultimately for the benefit not only of people suffering from Myasthenia Gravis but also of those with ptosis from other aetiologies.Trust Saidi...
The differential diagnosis of binocular vertical diplopia with ptosis can be organized broadly into neurogenic and myogenic etiologies. Neurogenic causes of ptosis and vertical diplopia include oculomotor nerve palsy and myasthenia gravis. While a ...
Other etiologies are traumatic, tumoral, vascular and infectious. The cause needs to be found by imaging over the entire course of the nerve. Cavernous sinus meningioma is one cause of third cranial nerve palsy. The surgical treatment of ptosis due to third cranial nerve palsy is levator ...
orerythrocyte countsare below two standard deviations from age-specific means. From a clinical standpoint, anemia has been broadly classified into three pathophysiological etiologies: 1) decreased hematopoietic production of erythrocytes, 2)blood loss, and 3) increased erythrocyte destruction inperipheral ci...
It has a number of aetiologies but one of the commoner causes is multiple surgeries to the chin and incorrect or failure of suspension of the mentalis muscle following closure. The mentalis muscle is unique in that it is the sole elevator of the lower lip and soft tissues of the chin and...
