Obstetrical forceps-induced Descemet membrane tears (FIDMT) are usually encountered during complicated forceps-assisted deliveries. The condition may lead to significant visual debilitation in young children and is frequently ignored due to its low incidence. Undue stretch on the Descemet's membrane during the process of forceps-assisted delivery results in their vertical/oblique tear (s), which usually leads to corneal edema in early neonatal life. On its resolution, these residual tears result in visually disabling astigmatism that can lead to dense and recalcitrant amblyopia. Slit-lamp examination, anterior segment optical coherence tomography, specular microscopy, confocal microscopy, and corneal topography and tomography can be employed for its accurate diagnosis. While these can be prevented by improved perinatal care, once diagnosed, they mandate prompt refractive correction and amblyopia therapy to prevent disabling visual deterioration in affected children. In adulthood, medical and surgical management may be planned for symptomatic patients based on coexistent amblyopia as this is the major factor guiding visual prognosis. There is limited comprehensive literature in this regard, and the present review discusses the pathogenesis, clinical features, and recent developments in investigations, management, and outcomes of FIDMT during the last three decades.
