Primary Cerebellopontine Angle Melanocytoma: Review [PDF]

Journal of Neurological Surgery Reports, 2012
Introduction Primary cerebellopontine angle melanocytomas (PCPAMs) are very rare. Their natural history and prognosis are not fully understood. We reviewed the literature and add a new case to analyze PCPAM's presentation, radiological features, and ...

Asymmetric Patterns of Visual Field Defect in Primary Open-Angle and Primary Angle-Closure Glaucoma [PDF]

Investigative Ophthalmology and Visual Science, 2018
Purpose: To compare the hemifield asymmetry of visual field (VF) loss in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) across all severity levels. Methods: A total of 522 eyes of 327 patients with POAG (mean age ± SD, 54.

Ocular perfusion in primary angle-closure suspect and primary angle-closure eyes without prior acute angle closure

Oman Journal of Ophthalmology
BACKGROUND: Acute intraocular pressure (IOP) spike in acute primary angle closure (APAC) decreases ocular blood flow. It is not known if this is true in primary angle-closure (PAC) eyes without prior APAC who may have had subacute attacks.

Color vision and contrast sensitivity changes in patient with primary angle closure and primary angle closure glaucoma

Oman Journal of Ophthalmology
PURPOSE: The purpose of the study was to assess color vision (CV) and contrast sensitivity (CS) in patients with primary angle closure glaucoma (PACG) and primary angle closure (PAC) and to correlate these changes with age-matched controls.

Simplifying “target” intraocular pressure for different stages of primary open-angle glaucoma and primary angle-closure glaucoma

Indian Journal of Ophthalmology, 2018
Lowering of intraocular pressure is currently the only therapeutic measure for Glaucoma management. Many longterm, randomized trials have shown the efficacy of lowering IOP, either by a percentage of baseline, or to a specified level.

Minimally Invasive Glaucoma Surgery in Primary Angle-Closure Glaucoma

Asia - Pacific Journal of Ophthalmology, 2022
Primary angle-closure glaucoma (PACG) is responsible for half of the glaucoma-related blindness worldwide. Cataract surgery with or without trabeculectomy has been considered to be the first-line treatment in eyes with medically uncontrolled PACG.
