INTRODUCTION Corneal thinning disorders caused by keratoconus often lead to protrusion, irregular astigmatism, and even perforation. Keratoconus, like other corneal ectasia, does not have a known cause. Severe cases of keratoconus may require correction or restoration of tectonic integrity of the cornea by surgical means. Intracorneal ring segments are a new modality in the treatment of corneal...
Sympathetic ophthalmia caused by a severe ocular chemical burn: a case report and literature review.
We herein presented a case of sympathetic ophthalmia induced by chemical burns. A 39-year-old male was referred to our retinal clinic complaining of sharply decreased vision in his right eye, with photophobia and headache. He had suffered severe chemical burns five months ago, and his left eye underwent amniotic membrane transplantation combined with tarsorrhaphy for persistent corneal ulcerati...
Fungal keratitis is a severe and common ocular infectious disease. The present study evaluated the efficiency of full-thickness conjunctival flap covering surgery with amniotic membrane transplantation (FCCS + AMT) as a transitional surgery for severe fungal keratitis. A total of 17 patients with severe fungal keratitis without corneal perforation underwent FCCS + AMT between January 2010 and D...
Background and Objective: Astigmatism is a common complication of penetrating (PK) and Lamellar (LK) keratoplasty that may cause surgical failure due to visual disturbances. In this study, the efficacy of scar revision just at the surgical incision was evaluated. Materials and Methods: In this prospective interventional case-series study, scar revision was performed in nineteen post-PK or LK as...
To the Editor: Alkali burn (AB), one of the most devastating types of ocular trauma, often develops secondary dry eye, which, in turn, worsens ocular surface disorder. The corneal epithelium is the first defensive line of the eye involved in pathogen-associated molecular pattern recognition that leads to robust innate immune responses. However, how damage-associated molecular pattern recognitio...
