To evaluate the characteristics of ocular injury in patients with severe extensive thermal burns, and to explore the effective methods to prevent and treat corneal ulcers related to severe burns. A retrospective case series study. Between 2010 and 2019, Sixteen severe thermal burn patients with burn sizes>70% of the total body surface area involving the ocular region were admitted to the Burns and Plastic Surgery Division of Chinese PLA General Hospital, and consult with Ophthalmology Division. There were deep second-degree to fourth-degree burns in the eyelids. In the eleven surviving patients, 22 eyes presented ectropion. Eyelid full-thickness skin grafting (EFTSG) combined with or without tarsorrhaphy was performed in 20 eyes due to severe corneal exposure. Two eyes received partial blepharorrhaphy because of mild ectropion. The ocular manifestations and treatment outcomes were reviewed and assessed. The majority of the patients were youth, and the average age was (36.8±10.4) years. The burn area was 84.0%±9.1% of the body surface area. Corneal ulcers secondary to lagophthalmos occurred at (35.1±15.6) days after burning in 75% (24/32) of eyes. Perforation was found in 18.8% (6/32) of eyes. Among the 22 operated eyes, the corneal ulcer was repaired in all 9 eyes receiving EFTSG with tarsorrhaphy, whereas ectropion recurred in 8 of 11 eyes only receiving EFTSG, and 4 eyes underwent further surgery due to corneal epithelial defects. In patients with severe large-area thermal burns, corneal ulcers are common complications. Prevention of corneal exposure is vital because the treatment of corneal ulceration is difficult due to eyelid deformity, inflammation and the absence of donor skin. Timely full-thickness skin grafting and blepharorrhaphy are effective approaches to preventing exposure keratopathy. To severe ulcers occur, conjunctival flap or Tenon's capsule covering combined with eyelid EFTSG and tarsorrhaphy is useful to rescue visual function.

Department of Ophthalmology, Medical University of Graz, Graz, Austria.
Purpose: To retrospectively describe the performance of topical insulin in persistent corneal epithelial defects (CED) and persistent corneal ulcers.
Methods: We reviewed cases of patients treated for persistent CED and persistent corneal ulcers using topical insulin in a concentration of 25 IU per milliliter three times per day. The closure rate of CED and corneal ulcers was the main outcome measure.

Corneal ulcer is one of the most important ophthalmic emergencies. A portable, recordable, and smartphone-attachable slit-lamp device called the "Smart Eye Camera" (SEC) is introduced to compare evaluating corneal ulcers between the SEC and the conventional slit-lamp. A total of 110 participants were included in the study, consisting of 55 patients with corneal ulcers and 55 age- and gender-matched healthy volunteers as controls.

Department of Optometry, University of Benin, Benin City, Nigeria.
Contact lenses have become integral tools in the realm of ocular therapeutics, extending beyond their primary function of refractive correction to encompass a diverse array of therapeutic applications. This review explores the evolving role of contact lenses in managing various ocular conditions, highlighting their efficacy in enhancing patient outcomes. Initially developed to correct refractive errors, contact lenses now serve as effective vehicles for delivering medications directly to the ocular surface, offering targeted treatment for conditions such as dry eye syndrome and corneal ulcers.

Background: Human anterior lens capsules (ALCs) have great potential in the treatment of multiple eye diseases, including corneal ulcers, glaucoma, age-related macular degeneration and macular holes. ALCs are also regarded as promising scaffolds for various ocular cells. Here, we investigated different decellularization methods for removing lens epithelial cells (LECs) that adhered to ALCs.
