Prosopagnosia

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Ophthalmology
Psychiatry
Neurology

Background:

Conversion disorders are common psychological issues.
Pseudoptosis is an uncommon manifestation of conversion disorders.

Observation:

Two cases of psychogenic pseudoptosis are presented: a 21-year-old male with intermittent left upper eyelid drooping and a 10-year-old female with ptosis after conjunctivitis.
Both patients exhibited signs suggestive of nonorganic ptosis.
Neurological and paraclinical assessments were unremarkable for both individuals.

Findings:

Significant familial or social stressors were identified in both cases.
Psychological treatment was administered to both patients.
No recurrence of symptoms was noted post-treatment.

Implications:

This highlights the importance of considering psychological factors in unexplained ptosis.
Psychological interventions can be effective in managing psychogenic pseudoptosis.
Further research into the neurobiological underpinnings of conversion disorders is warranted.
