The purpose of this study was to evaluate the use of the conjunctival oxygen tension (PCJO2) monitor during the early assessment of injured patients in the A&E Department of a large District General Hospital. The conjunctival oxygen sensor provides a non-invasive continuous monitor of tissue oxygenation in the palpebral conjunctiva and has been shown to detect early hypovolaemia in animal and h...

Pterygium is an abnormal overgrowth of the conjunctiva onto the cornea. Surgical management is the choice of treatment when persistent discomfort, visual distortion, and restricted ocular motility bothers patient’s life.1 Although an easy procedure, the main problem with the surgical excision of the pterygium is the recurrence rate, which can be as high as 30 to 82% (1-3). Recurrence is usually...

All across the world, glaucomatologists are adopting broader use of glaucoma drainage implants even as a primary surgical modality. To avoid tube exposure, which may predispose the eye to endophthalmitis, the implanted tube must be covered by a patch graft. However, these patch grafts also carry a high rate of progressive thinning and erosion, which is believed to result from the lack of cellul...

We report the case of a patient who showed spontaneous regression of bilateral conjunctival extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). A 72-year-old man underwent excisional biopsy for salmon-pink lesions involving the whole circumference of the conjunctiva in the right eye and the lower fornix in the left eye. Histopathology and immunohistoch...

PURPOSE We describe a case of full-thickness corneal restoration after an acute corneal burn with an acid agent. METHODS A 32-year-old male reported painful discomfort, redness, photophobia, and a decrease in visual acuity in the left eye after a unilateral burn with an acid agent. Slit-lamp examination revealed massive corneal melting involving necrotic sequestrum of the entire corneal surfa...

Based on previous findings that ozone can induce an inflammatory response in the ocular surface of an animal model and in cultured human conjunctival epithelial cells, we investigated whether exposure to ozone exacerbates symptoms of allergic conjunctivitis. We evaluated the effects of exposure to ozone on conjunctival chemosis, conjunctival injection, corneal and conjunctival fluorescein stain...

ABSTRACT Domestic buffalo production plays an economically important role in the Brazilian Amazon, but they are susceptible to many diseases favored by tropical climate and annually flooded habitats, including ocular diseases. In this context, it is select genotypes that maximize innate immunity Amazonian herds. We aimed characterise, for first time, gene expression profiles of immune system co...

Of 57 patients with chronic renal failure who all had deposition of calcium salts in the conjunctival and corneal tissue two developed a brief episode of painful irritation and redness of the conjunctiva and subconjunctiva. This hyperaemia was adjacent to erosions of the corneal epithelium of the eye as a consequence of exfoliation of calcium concretions from the superficial corneal epithelium....

MANAGEMENT of conjunctival ulceration in the acute stages following chemical injuries and certain infectious diseases is one of the most difficult problems confronting ophthalmic surgeons. This is challenging, more so when the internal structures of the eye-ball are not affected. The cornea may be fairly normal in many such cases. Severe damage to the conjunctiva, unless properly treated, will ...
