Primary Angle Closure Suspect (PACS): represents the first stage, in which there is reversible contact between the peripheral iris and trabecular meshwork (irido-trabecular contact [ITC] in at least two quadrants).
The earliest stage of angle closure is the ‘angle closure suspect.’ In these persons, the iris blocks the view of the TM during gonioscopy for at least half of the angle, but the eye pressure (IOP) is normal and the optic nerve is healthy.
Jun 1, 2021 · The progression of angle closure was defined as the presence of primary angle closure (PAC)/primary angle-closure glaucoma (PACG) during the follow-up in subjects with PACS at baseline. Ocular data from the right eye were used for cases with bilateral PACS and unilateral PACS in the right eye at baseline.
Primary angle-closure suspect (PACS) or anatomic narrow angle – An eye in which the anterior chamber angle recess has an abnormally narrow angular width. The peripheral iris is located close to, but not touching, the posterior pigmented trabecular meshwork (TM).
Primary angle-closure suspect (PACS), defined as ≥180 degrees of iridotrabecular contact, is generally benign, but it has been shown to progress to primary angle closure (PAC) or primary angle-closure glaucoma (PACG).
Nov 19, 2017 · Primary angle-closure suspect (PACS) was defined as nonvisibility of the filtering trabecular meshwork for 180° or more in the absence of PAS with normal intraocular pressure (IOP). Primary angle...
Primary angle closure suspect is defined as ≥ 180 degrees of iridotrabecular contact (ITC) without intraocular pressure (IOP) elevation, peripheral anterior synechiae (PAS), or optic nerve damage.
Nov 26, 2023 · Acute closed-angle glaucoma (ACAG) is a subset of primary angle-closure glaucoma. Acute angle-closure (AAC) is an ophthalmologic emergency with elevated IOP, posing a risk of irreversible damage and potential blindness not treated promptly.
This review provides a practical approach to individuals classified as glaucoma suspects caused by one or more of the following risk factors or indicators of disease: ocular hypertension, optic nerve features suggestive of glaucoma, visual field abnormalities, and other characteristics placing them at greater risk than the average population.
The scope of this guideline covers the primary angle-closure spectrum only and specifically excludes secondary disease such as that resulting from uveitis or neovascularization. This guideline has been written primarily for clinicians involved in eye care in the community and in hospital
