Xerophthalmia developed in the eyes of rabbits maintained on a vitamin A-deficient diet for 4 to 6 months. The earliest clinical change, a lusterless graying of the central corneal epithelium, was noted after 16 to 18 weeks on the diet. Multiple small punctate epithelial erosions appeared in the interpalpebral fissure zone within 7 to 10 days after the lusterless graying became evident. The ero...

Seventy-eight dogs and ten cats with corneal lesions, including deep corneal stromal ulcers (n = 32), keratomalacia and recurrent erosions (n = 25), descemetocoeles (n = 18), staphylomas and perforating corneal defects (n = 5...

Our patient was diagnosed with cicatricial pemphigoid (CP) in 2001. She demonstrated classic clinical findings and underwent biopsies that supported this diagnosis. She unfortunately experienced severe CP involving both of her eyes, oral mucosa, pharyngeal mucosa, and esophagus. Her left eye was seriously affected early in the course of her disease. She experienced significant scarring of the c...

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 evaluate the effect of platelet-rich plasma (PRP) eye drops in the treatment of recurrent corneal erosions (RCE). METHODS A total of 47 eyes were included in this retrospective study. Clinical records of 20 consecutive patients with RCE who had been treated with conventional lubricant eye drops (conventional treatment group) from June 2006 to December 2008 and 27 consecutive patien...

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...

animal models for h.pylori infection have been developed to clarify the pathogenesis, testing new therapies and developing vaccines against human h.pylori infection. although rats have been used extensively for gastric ulceration and acid secretion studies, the animal is not normally infected with h.pylori.several chemicals such as ethanol and ammonium hydroxide can induce gastric erosion and i...
