We report a case of a 27-year-old male presenting with blurred vision in one eye which was discovered at an army recruitment camp. He was examined and subsequently diagnosed to be having Descemet's membrane tears, due to forceps-induced birth trauma with amblyopia. His vision improved with a rigid gas permeable contact lens to 20/60.

A 27-year-old male presented with blurred vision in the left eye, discovered when he appeared for an army recruitment screening camp. Best-corrected visual acuity was 20/20 in the right eye and 20/300 in the left eye. Examination revealed multiple vertically oriented tears in the Descemet's membrane (DM) with rolled edges and clear and compact intervening cornea [Figure 1]a, [Figure 1]b and [Figure 1]d. Posterior-segment evaluation revealed no abnormality. There was a definitive history of forceps-assisted delivery. A scar on the left maxillofacial area [Figure 2]b further affirmed the diagnosis of a birth injury due to forceps-assisted delivery. Specular microscopy revealed marked pleomorphism and polymegathism [Figure 2]a, with a peripheral cell density of 1575. A rigid gas permeable (RGP) contact lens trial improved his vision to 20/60.

| Discussion|| |
Breaks in the DM due to birth trauma can be easily distinguished from the horizontal random breaks of congenital glaucoma, which are concentric to the limbus. Left eyes seem to be affected more commonly than right eyes because neonates usually present in the left occiput-anterior position. It is hypothesized that the tip of the forceps slips over the anterior orbital rim causing vertical compression and horizontal distension of the globe, thus elevating the intraocular pressure acutely and resulting in tears of the nonelastic DM., The young endothelium resurfaces the DM defect and the postnatal corneal edema clears. The tears are seen as clear, glassy ridges in the posterior cornea evident on retroillumination. A large proportion of cases have high Degrees of astigmatism [Figure 1]c contributing to poor vision., Management options include spectacles, RGP lenses, and keratoplasty.
DM tears due to birth injury are quite uncommon in the present era, owing to good prenatal care, planning, and increasing Caesarian Section rates. As visual problems go undiagnosed until the child realizes or secondary complications develop, it also adds to the existing burden of amblyopia.
