Mar 12, 2018 · Dr. Thompson defined pseudomacular holes as a clinical diagnosis as seen via slit lamp biomicroscopy versus optical coherence tomography (OCT). “Use pseudomacular holes only to describe the biomicroscopic appearance,” he added. In contrast, a lamellar macular hole is defined by the appearance of the fovea via OCT.

Jul 1, 2011 · Vitreomacular interface pathology is a term used to describe a group of conditions involving the macula, consisting of full-thickness macular holes (FTMH), lamellar macular holes (LMH), macular pseudoholes (MPH), vitreomacular traction (VMT) and myopic macular schisis.

Jul 1, 2021 · Lamellar macular holes have an irregular contour with a break in the inner fovea without a break in the outer retina. There are often overhang­ing edges over the inner foveal defect on OCT. The Watzke-Allen sign is negative. Macular pseudoholes associated with epiretinal membranes appear as a central reddish spot in the fovea with a ...

Lamellar macular hole (LMH) is a retinal disorder that affects the macula involving a loss of tissue in the inner layers of the retina. The majority of LMH cases are idiopathic.

Jan 27, 2025 · Lamellar and pseudoholes. A, Lamellar macular hole. OCT 5-mm scan showing a thinned and irregular foveal base (75 μm) with superficial retinal edges separated from deeper layers. The perifoveal retina is of normal thickness (240 μm). B, Macular pseudohole. OCT 5-mm scan showing epiretinal membrane and superficial retinal folds.

ACULAR PSEUDOHOLE (MPH) AND LAMELLAR macular hole (LMH) are two different entities whose only common feature is the round and reddish appearance of the macula. Each entity may constitute a differential diagnosis for full-thickness macular hole (FTMH). Their pathogenesis is different. The pseudohole is attrib-

lamellar macular hole and pseudohole, among others.2 Lamellar macular holes have an irregular contour with a break in the inner fovea without a break in the outer retina. There are often overhang­ ing edges over the inner foveal defect on OCT. The Watzke­Allen sign is negative. Macular pseudoholes associated with epiretinal membranes appear as a

Abstract: : Purpose: To assess the usefulness of Optical Coherence Tomography (OCT) in distinguishing lamellar macular holes from pseudoholes caused by contraction of an epiretinal membrane (ERM) . Methods: 71eyes of 70 patients (39 females and 31 males) exhibiting a false macular hole appearance on biomicroscopy, were examined by OCT.

Macular holes and macular pseudoholes can cause dark spots right in the center of your vision, causing vision loss. Learn about treating macular holes and more.

Aug 6, 2008 · Lamellar macular defects were categorised into three different subtypes based on their OCT appearance: macular pseudoholes (MPH), lamellar macular holes (LMH) and foveal pseudocysts (FP). Lamellar macular defects which had a sharply punched out, well-delineated, steepened foveal contour were classified as MPH.
