PURPOSE To examine the role of Bowman's layer (BL) on the nature of anterior corneal regeneration after excimer laser phototherapeutic keratectomy (PTK). METHODS A cohort of 13 patients underwent PTK to remove either 7 mum of BL for treatment of primary recurrent corneal erosions (RCE; six patients) or complete BL removal (15-mum ablation) to treat RCE or poor vision secondary to map-dot-fing...

PURPOSE To compare the outcomes of bandage contact lens (BCL) removal on the fourth versus seventh post-operative day following photorefractive keratectomy (PRK). METHODS This study recruited eyes of patients who underwent PRK surgery. The patients were randomly assigned to 2 groups. In Group 1 BCL was removed on the 4th postoperative day, while in Group 2, BCL was removed on the 7th postoper...

1 Mustard gas is a lipophilic, highly cytotoxic agent that rapidly penetrates tissue, and the eye is one of the organs mostly affected,[1] but skin, respiratory, gastrointestinal, and renal systems as well as the bone marrow may also be affected.[2] Mustard gas related ocular injuries can be divided into immediate, chronic, and delayed‐onset phases. Acute manifestations of varying degrees, incl...

PURPOSE To investigate the clinical characteristics of Mooren's ulcer in East China and to identify the potential risk factors that affect the recurrence of Mooren's ulcer. METHODS We reviewed the medical records of 95 patients (100 eyes) diagnosed with Mooren's ulcer from May 2005 to December 2014. The patients were classified into recurrent and nonrecurrent groups and followed up for 18 mon...

Lesions on the ocular surface can destroy the stem cells from the limbus and cause limbal stem cell deficiency. The limbal stem cell deficiency is marked by conjunctivalization, which can be defined as the invasion of conjunctival epithelium over the cornea. This process is accompanied by varying degrees of corneal changes such as neovascularization, inflammation, recurrent erosions, persistent...

On initial examination, the patient was found to have a right preauricular skin appendage, visual acuity of light perception in both eyes, a small right eye temporal limbal dermoid, and a right upper eyelid coloboma that involved approximately 70%–80% of the upper eyelid. There was near total exposure of the right corneal surface, with trace inferior punctate epithelial erosions but no epitheli...
