“…The reported prevalence of LMH in different populations has ranged anywhere from 0.1% to 3.6% [ 18 , 19 , 20 , 21 , 22 ]. Most people who develop a LMH are older than 50 years of age [ 18 , 19 , 20 ].…”

There is a wide spectrum of macular conditions that are characterized by an irregular foveal contour caused by a break in the inner fovea. These include full-thickness macular hole (FTMH), foveal pseudocyst, lamellar macular hole (LMH) and macular pseudohole (MPH). Clinical examination of vitreomacular interface disorders is notoriously poor in differentiating these conditions. These conditions were initially described with slit-lamp biomicroscopy, and the main goal was to distinguish an FTMH from the others. The introduction of optical coherence tomography (OCT) has revolutionized our understanding of the foveal microstructural anatomy and has facilitated differentiating these conditions from an FTMH. However, the definitions of the other conditions, particularly LMH, has evolved over the past two decades. Initially the term LMH encompassed a wide spectrum of clinical conditions. As OCT became more widely used and observations became more refined, two different phenotypes of LMH became apparent, raising the question of different pathogenic mechanisms for each phenotype. Tractional and degenerative pathological mechanisms were proposed. Epiretinal membranes (ERMs) associated with each phenotype were identified. Typical ERMs were associated with a tractional mechanism, whereas an epiretinal proliferation was associated with a degenerative mechanism. Epiretinal proliferation represents Müller cell proliferation as a reactive process to retinal injury. These two types of ERM were differentiated by their characteristics on SD-OCT. The latest consensus definitions take into account this phenotypic differentiation and classifies these entities into LMH, MPH and ERM foveoschisis. The initial event in both ERM foveoschisis and LMH is a tractional event that disrupts the Müller cell cone in the foveola or the foveal walls. Depending on the extent of Müller cell disruption, either a LMH or an ERM foveoschisis may develop. Although surgical intervention for LMH remains controversial and no clear guidelines exist for pars plana vitrectomy (PPV), eyes with symptomatic, progressive ERM foveoschisis and LMH may benefit from surgical intervention.

Cataracts can cause visual impairment in diabetic patients. Diabetes mellitus affects different parts of the eye and causes many complications and problems before, during, and after intraocular surgeries. In this review, we will discuss the effects of diabetes on different aspects of cataract surgery and review the current management of diabetic cataracts. Careful preoperative examination of the patient's ocular surface, cornea, iris, and posterior segment, as well as the use of advanced phacoemulsification techniques, new intraocular lenses and the appropriate use of auxiliary medications such as nonsteroidal anti-inflammatory drugs and anti-vascular endothelial growth factors have improved the outcomes of cataract surgery in diabetic patients.
