Queratoplastia penetrante temprana después de queratitis fúngica de la interface en la queratoplastia endotelial de la membrana de Descemet

In this case-report we describe the first reported case of early-onset fungal interface keratitis (IK) after Descemet Membrane Endothelial Keratoplasty (DMEK) successfully treated with penetrating keratoplasty (PK) during the active stage of infection. A patient with graft failure after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) was operated on with DMEK. Donor rim culture and broth were positive for Candida albicans. Several interface infiltrates were confirmed and localized using anterior segment optical coherence tomography. Three days after diagnosis, observing clear signs of intraocular infection, the graft was removed with simultaneous washed-up of anterior chamber with fluconazole 1% followed by a PK and intrastromal corneal injections of fluconazole. A best-corrected visual acuity of 20/20 was achieved. This case highlights the importance of analysing every donor rim and broth, despite the patient doesn’t show any symptoms or signs during the post-operative period. PK is a viable treatment option in early-onset interface keratitis.     

Variante de la técnica de Nishida para la corrección quirúrgica del síndrome de déficit monocular de la elevación

Monocular elevation deficiency (MED) is characterized by unilateral limitation of supraductions, similar in adduction and abduction, in addition to hypotropia and ptosis. We describe a case of a 62-year-old woman with long-standing left ptosis who was initially operated with a frontal suspension technique. On subsequent examinations, a MED of that eye was found. The passive duction test was positive, so the inferior rectus was recessed. In addition, a modified Nishida technique was performed, consisting of the scleral anchorage of the superior edges of the rectus, medial and lateral, 12 mm from the corneal limbus in the superonasal and superotemporal quadrants, respectively. Postoperatively, the left eye presented a minimal hypotropia of 3 PD. This modified technnique used here on the horizontal rectus muscles, turned out to be effective and safe for the correction of MED.
