A 47-year-old lady presented with inaccurate projection of rays in her right eye and blurred vision of counting fingers in the left eye since 10 days. Both the eyes had blue sclera. Slit-lamp biomicroscopy revealed bilateral keratoglobus and adherent leukoma with left eye acute hydrops due to Descemet's membrane detachment (DMD) [Figure 1]a and [Figure 1]b] confirmed by anterior segment ocular coherence tomography (OCT) [Figure 1]c. The wide Descemet's membrane (DM) rip and marked ectasia precluded successful air descemetopexy. Being monocular, an early DSAEK was advised for tectonic support to the thin cornea and quick visual rehabilitation. To avoid tearing of the fragile cornea, a 7.5 mm diameter lenticule was pushed through a scleral incision over a Sheet's glide, which decentered superiorly with the reverse Sinskey due to the inferior adherent leukoma and avoided stroking, since the cornea was brittle. All surgical incisions were sutured with long intrastromal 10-0 nylon bites. Air bubble tamponade was difficult due to posteriorly migrating air bubble. Postoperatively, lenticule was attached, stromal edema resolved and vision improved to 20/400 [Figure 2]a and [Figure 2]b. A challenging phacoemulsification with intraocular lens implantation was done 9 months later. The technical issues, included paracentesis extension and phacoemulsification, in a shallow anterior chamber (AC) due to adherent leukoma while protecting the DSAEK lenticule. At 2 years follow-up her vision is 20/125 [Figure 3]a and [Figure 3]b.{Figure 1}{Figure 2}{Figure 3}

 Discussion



The management of acute hydops in keratoglobus can be conservative or surgical.[1] Gas tamponade was not as effective in keratoglobus[2] and unsuccessful in our case due to large rip with thickened fibrosed edges and marked ectasia.

Surgical management of keratoglobus is challenging, since the tissue is thin and fragile.[3] Conventional penetrating keratoplasty is associated with numerous surgical challenges due to limbus to limbus thinning, thin sclera, and marked disparities in the recipient and host tissue. There has been a single case of DSAEK for keratoglobus with chronic hydrops due to spontaneous Descemet's membrane tear.[4] We demonstrated that for nonresolving corneal hydrops in keratoglobus, DSAEK followed by cataract surgery, though technically demanding, provided gratifying and early visual rehabilitation.
