Rapid adaptation of visual search in simulated hemianopia [PDF]

, 2010
Patients with homonymous hemianopia have altered visual search patterns, but it is unclear how rapidly this develops and whether it reflects a strategic adaptation to altered perception or plastic changes to tissue damage.

Seven years follow-up of a case of acute zonal occult outer retinopathy

Indian Journal of Ophthalmology. Case Reports
We describe the case of a 43-year-old South Asian man who presented with a long-standing history of gradual narrowing and blurring of his side vision. Despite maintaining normal visual acuity, multimodal imaging at presentation already revealed signs of ...

Visual morbidity in macroprolactinoma: A retrospective cohort study

Clinical Endocrinology, Volume 101, Issue 6, Page 648-658, December 2024.
Abstract Objective The management of visual field damage in patients with macroprolactinomas is a major therapeutic challenge. We aimed to study the visual morbidity associated with macroprolactinoma and its outcomes following medical and surgical treatment. We aimed to identify predictors of visual recovery. Methods We retrospectively reviewed patient'

Hemifield slide phenomenon in a patient with bitemporal hemianopia

Hong Kong Journal of Ophthalmology, 1999
Pituitary tumor is by far the most common perichiasmal tumor. It can compress the chiasm resulting in visual field defect, classically bitemporal hemianopia. A dense bitemporal hemianopic scotoma can cause hemifield slide phenomenon. This brief report describes a patient with this phenomenon resulting in nonparetic diplopia. With orthoptic ...

Pituitary hyperplasia secondary to primary hypothyroidism in adolescents: A medical case report and literature review

Clinical Case Reports, Volume 12, Issue 11, November 2024.
Key Clinical Message Prompt and precise diagnosis of pituitary hyperplasia secondary to primary hypothyroidism (PHPH) is crucial to avoid unwarranted pituitary surgery and potential permanent impairment. Although PHPH may present similarly to pituitary adenoma, it is responsive to thyroxine therapy, underscoring the critical role of differential ...

Optic Chiasmal Abnormality On MRI In Ethambutol Induced Bitemporal Hemianopia

, 2013
Ethambutol induced optic neuropathy is known to cause central and cecocentral scotomas, but bitemporal visual field defects are also reported. The exact pathogenesis and location of the lesion in bitemporal hemianopia is poorly understood.

Line bisection in simulated homonymous hemianopia

, 2010
Hemianopic patients make a systematic error in line bisection, showing a contra-lesional bias towards their blind side, which is the opposite of that in hemineglect patients.
