Crescentic Tuck in Lamellar Keratoplasty-A Novel Technique in a Case of Advanced Pellucid Marginal Corneal Degeneration.

Purpose: To describe a new surgical technique "crescentic tuck in lamellar keratoplasty" for the management of advanced pellucid marginal corneal degeneration (PMCD).

Methods: A 45-year-old man with advanced PMCD and maximal thinning in the inferior juxtalimbal periphery underwent a crescentic lamellar keratoplasty in the right eye. Best-corrected visual acuity was 6/60 with no further improvement because of severe irregular astigmatism.

Preliminary results from the comparison of simple limbal epithelial transplantation with conjunctival limbal autologous transplantation in severe unilateral chronic ocular burns.

Purpose: To compare the safety, efficacy, and clinical outcomes of simple limbal epithelial transplantation (SLET) with conjunctival-limbal autologous transplantation (CLAU) in severe unilateral ocular chemical burns.

Materials And Methods: Twenty patients of unilateral chronic ocular burns with more than 270° limbal stem cell deficiency and a healthy fellow eye were divided into two groups - ten patients of Group A underwent SLET while ten patients of Group B were operated for CLAU. Patients were followed up for 6 months and assessed for a stable epithelialized ocular surface, extent of reduction in vascularization and forniceal reconstruction, improvement in corneal clarity and visual acuity.

Results of Deep Anterior Lamellar Keratoplasty for Advanced Keratoconus in Children Less Than 18 Years.

Purpose: To evaluate the outcomes of deep anterior lamellar keratoplasty (DALK) in children with advanced keratoconus.

Design: Retrospective noncomparative interventional case series.

Methods: A retrospective analysis was conducted of 20 eyes of 16 patients who underwent deep anterior lamellar keratoplasty at a tertiary eye care center for advanced keratoconus.

Role of corneal collagen cross-linking in pseudophakic bullous keratopathy: a clinicopathological study.

Objective: To evaluate the clinical and histopathologic changes induced by collagen cross-linking (CXL) in pseudophakic bullous keratopathy (PBK).

Design: Randomized, prospective, interventional study.

Participants: Twenty-four patients with PBK were included in the study.

Congenital accessory palpebral aperture--an addition to the spectrum of Delleman syndrome.

Delleman syndrome (oculocerebrocutaneous syndrome, MIM 164180) is characterized by orbital cysts, microphthalmia/anophthalmia, focal skin defects, skin appendages and multiple cerebral malformations. We herein describe a case of an 8-month-old male child with features suggestive of Delleman syndrome along with a rare congenital lid anomaly - an accessory palpebral aperture, not reported so far to the best of our knowledge.
