“…To our knowledge, this was the largest case series to have quantified corneal aberrations and clinical data in eyes with forceps corneal injuries. Owing to the small number of cases, previous studies have included samples of only one to 12 patients [1][2][3][6][7][8][19][20][21][22][23][24][25][26] . Therefore, it has been difficult to accurately characterise clinical features such as the degree of regular and irregular astigmatism, incidence of amblyopia, corneal structure, and optical properties.…”

Forceps corneal injuries during infant delivery cause Descemet membrane (DM) breaks, that cause corneal astigmatism and corneal endothelial decompensation. The aim of this study is to characterise corneal higher-order aberrations (HOAs) and corneal topographic patterns in corneal endothelial decompensation due to obstetric forceps injury. This retrospective study included 23 eyes of 21 patients (54.0 ± 9.0 years old) with forceps corneal injury, and 18 healthy controls. HOAs and coma aberrations were significantly larger in forceps injury (1.05 [0.76–1.98] μm, and 0.83 [0.58–1.69], respectively) than in healthy controls (0.10 [0.08–0.11], and 0.06 [0.05–0.07], respectively, both P < 0.0001). Patient visual acuity was positively correlated with coma aberration (rs = 0.482, P = 0.023). The most common topographic patterns were those of protrusion and regular astigmatism (both, six eyes, 26.1%), followed by asymmetric (five eyes, 21.7%), and flattening (four eyes, 17.4%). These results indicate that increased corneal HOAs are associated with decreased visual acuity in corneal endothelial decompensation with DM breaks and corneal topography exhibits various patterns in forceps injury.

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.

Nam, 21 tuổi, đến khám để phẫu thuật cận thị hai mắt. Bệnh nhân có tiền sử can thiệp forceps khi sinh. Khám lâm sàng thấy có vết sẹo cung mày góc ngoài bên phải, giác mạc mắt phải trong, có vết rách màng Descemet chạy theo hướng chéo từ vùng rìa 6 giờ đến gần rìa 2 giờ kèm theo bong màng Descemet tại mép rách phía thái dương. Vùng bong màng Descemet chiếm 14,5% diện tích giác mạc. Mật độ tế bào nội mô trung bình bên mắt bị tổn thương là 1365 tế bào/mm2, bằng một nửa so với mắt lành. Tại vùng bong màng Descemet có sự di cư và giãn rộng của tế bào nội mô với hệ số biến thiên tế bào cao (CV 73%), tỉ lệ tế bào 6 cạnh thấp (44%). Bệnh nhân được chẩn đoán rách màng Descemet mắt phải do tiền sử lúc sinh có can thiệp forceps. Mặc dù diện tích rách và bong màng Descemet chiếm 14,5% diện tích giác mạc, giác mạc vẫn trong suốt nhờ sự giãn ra và bù trừ chức năng của các tế bào nội mô lân cận. Bệnh nhân cần được theo dõi định kì để đánh giá thay đổi tế bào nội mô và ghép nội mô giác mạc khi có tăng độ dày giác mạc do tế bào nội mô mất bù.
