Corneal perforation. Medical search

A puncture or hole through the CORNEAL STROMA resulting from various diseases or trauma.

Loss of epithelial tissue from the surface of the cornea due to progressive erosion and necrosis of the tissue; usually caused by bacterial, fungal, or viral infection.

Deeply perforating or puncturing type intraocular injuries.

Opening or penetration through the wall of the INTESTINES.

Infections in the inner or external eye caused by microorganisms belonging to several families of bacteria. Some of the more common genera found are Haemophilus, Neisseria, Staphylococcus, Streptococcus, and Chlamydia.

Diseases of the cornea.

Infection by a variety of fungi, usually through four possible mechanisms: superficial infection producing conjunctivitis, keratitis, or lacrimal obstruction; extension of infection from neighboring structures - skin, paranasal sinuses, nasopharynx; direct introduction during surgery or accidental penetrating trauma; or via the blood or lymphatic routes in patients with underlying mycoses.

Inflammation of the cornea.

Partial or total replacement of all layers of a central portion of the cornea.

Tear or break of an organ, vessel or other soft part of the body, occurring in the absence of external force.

The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)

An opening or hole in the ESOPHAGUS that is caused by TRAUMA, injury, or pathological process.

Infection, moderate to severe, caused by bacteria, fungi, or viruses, which occurs either on the external surface of the eye or intraocularly with probable inflammation, visual impairment, or blindness.

Lenses designed to be worn on the front surface of the eyeball. (UMDNS, 1999)

Infections with bacteria of the genus SERRATIA.

Substances used to cause adherence of tissue to tissue or tissue to non-tissue surfaces, as for prostheses.

Infections with bacteria of the genus PSEUDOMONAS.

A temporary or persistent opening in the eardrum (TYMPANIC MEMBRANE). Clinical signs depend on the size, location, and associated pathological condition.

A hole or break through the wall of the UTERUS, usually made by the placement of an instrument or INTRAUTERINE DEVICES.

Penetration of a PEPTIC ULCER through the wall of DUODENUM or STOMACH allowing the leakage of luminal contents into the PERITONEAL CAVITY.

Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.

The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.

A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.

A condition with trapped gas or air in the PERITONEAL CAVITY, usually secondary to perforation of the internal organs such as the LUNG and the GASTROINTESTINAL TRACT, or to recent surgery. Pneumoperitoneum may be purposely introduced to aid radiological examination.

Bursting of the STOMACH.

Inflammation of the eyelids.

The hairs which project from the edges of the EYELIDS.

The sebaceous glands situated on the inner surface of the eyelids between the tarsal plates and CONJUNCTIVA.

Infestations with arthropods of the subclass ACARI, superorder Acariformes.

Each of the upper and lower folds of SKIN which cover the EYE when closed.

Enhancing effects of sericin on corneal wound healing in Otsuka Long-Evans Tokushima fatty rats as a model of human type 2 diabetes. (1/15)

The protein sericin is the main constituent of silk. We investigated the effects of sericin on corneal wound healing in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a model for human type 2 diabetes. Corneal wounds were prepared by removal of the corneal epithelium, and documented using a TRC-50X equipped with a digital camera. Sericin solutions were instilled into the eyes of rats five times a day following corneal abrasion. Plasma glucose and triglycerides were determined using an Accutrend GCT. Cholesterol and insulin were measured using a Cholesterol E-Test Kit and ELISA Insulin Kit, respectively. The plasma levels of glucose, triglycerides, cholesterol and insulin in 38-week-old OLETF rats were significantly higher than in Long-Evans Tokushima Otsuka (LETO) rats used as normal controls, and the rate of corneal wound healing in OLETF rats was slower than in LETO rats. The corneal wounds of rats instilled with saline showed almost complete healing by 72 h after corneal epithelial abrasion. On the other hand, the corneal healing rate of OLETF rats instilled with 10% sericin solution was significantly higher than that of LETO rats instilled with saline, and the wounds showed almost complete healing at 48 h after abrasion. The corneal healing rate increased with increasing sericin concentration. The present study demonstrates that the corneal wound healing rate in OLETF rat is slower than in LETO rats, and the instillation of sericin solution has a potent effect in promoting wound healing and wound-size reduction in LETO and OLETF rats.

Four cases of corneal perforation in patients with chronic graft-versus-host disease. (4/15)

PURPOSE: To report the clinical features and investigate the underlying pathological processes of spontaneous corneal perforation in patients with ocular chronic graft-versus-host disease (cGVHD). METHODS: A full ophthalmological evaluation of corneal perforation in four patients with cGVHD was performed. Three of them underwent deep anterior lamellar keratoplasty and samples from two of three patients were used for histopathological analyses. RESULTS: Three patients were successfully treated by corneal transplantation. One patient was treated with a therapeutic soft contact lens, and the wound healed within 2 days. The common clinical features of these patients were (1) the presence of definite dry eye related to cGVHD in 3 of 4 patients and probable dry eye in one patient, (2) a central or paracentral site of corneal ulceration and perforation, with no sign of infection, and (3) prior use of a topical or systemic corticosteroid, and/or topical non-steroidal anti-inflammatory drugs. Immunohistochemical findings revealed an increased number of cluster of differentiation 68(+) (CD68(+)) macrophages and matrix metalloproteinase 9 (MMP-9) expression in the tissue surrounding the perforation. CONCLUSIONS: Our report extends current information on the clinical features and pathological processes of corneal perforation in cGVHD by showing increased MMP-9 expression and the accumulation of CD68(+) positive macrophages in the affected areas.

After applying the tissue adhesive , the dried membrane with glue applied then was positioned to cover the conjunctival bleb leak site or corneal perforation lesion using forceps . (bvsalud.org)

Postoperatively, the corneal perforations were successfully sealed in 16 (80%) patients, and 15 (75%) patients exhibited a statistically significant improvement in visual acuity ( P =0.02). (eg.net)
Upon presentation, the examination may include a best-corrected visual acuity examination, a slit-lamp examination, indirect ophthalmoscopy, and Goldmann applanation tonometry (measurement of intraocular pressure by pressing and flattening an area on the corneal surface). (uspharmacist.com)

After the microkeratome cut the corneal cap, it was stabilized with suction in the inverted position on a forming die while the refractive cut was made by a second pass of the instrument on the stromal side of the corneal cap. (aao.org)
The reshaped free cap was sutured onto the patient's corneal stromal bed. (aao.org)
In the late 1980s, Ruiz and Rowsey introduced tissue removal from the stromal bed rather than the free corneal cap, referred to as in situ keratomileusis. (aao.org)
Purpose The aim of this study was to evaluate the safety and efficacy of double stromal lenticules, extracted by femtolaser small incision lenticule extraction (SMILE) surgery, as a surgical adjuvant for sealing of impending corneal perforation. (eg.net)
Double corneal stromal lenticules obtained through SMILE surgery, with a central thickness of 65 μm for each lenticule, were fixed over the corneal impending perforation site by 10-0 nylon interrupted stitches. (eg.net)
CONCLUSION With this technique a deep stromal anterior lamellar keratoplasty can be performed with the donor to recipient interface just anterior to the posterior corneal surface. (bmj.com)
From the bottom of the incision, several corneal layers may be dissected until the desired depth of the recipient stromal bed is obtained. (bmj.com)
With all these techniques the stromal dissection depth relative to the corneal thickness cannot be optically visualised. (bmj.com)
If perforation occurs completion of the stromal dissection can be difficult, so that the donor button may have to be sutured into an imperfectly prepared recipient bed. (bmj.com)
Using an alkali burn model of corneal ulceration in rabbits, we studied the effects and efficacy of application of a topical model protease on a model corneal wound healing and stromal ulceration. (uveitis.org)
More importantly, corneal stromal ulceration was present in only 2 of the protease-treated eyes, whereas 46% of the placebo-treated eyes exhibited significant corneal ulceration. (uveitis.org)
These preliminary results from these pilot studies suggest that, in addition to ant-collagenolytic therapy (for example with citrate and with medroxyprogesterone and with tetracycline), enhanced degradation of collagenase through the use of krill protease may be additionally beneficial in limiting the progression of alkali burn-induced corneal stromal degradation and ulceration. (uveitis.org)
When used as a permanent graft, the aim of AMT is to fill in the corneal stromal defect. (osref.org)
After securing the AM filling the defect, a larger layer of AM with the stromal surface facing down is laid and sutured to the healthy stroma with 10-O nylon in either interrupted or running (either zig-zag or purse string) fashion to make sure the top layer of membrane, which will act as a permanent graft, is in close contact with the corneal surface. (osref.org)
with a long shelf-life and no need for refrigeration, it is a great solution for immediate availability in cases of near full thickness stromal replacement, such as in descemetoceles and even small perforating corneal defects in dogs and cats. (petseyes.cn)

Subconjunctival anti-infectives may be necessary if scleral spread or perforation is imminent. (drugs.com)
Of the 16 patients, two experienced severe keratopathy, three experienced ulceration, six experienced corneal or scleral melts, and five experienced perforations. (qxmd.com)

If the perforation site is more than 2 mm in diameter, a tectonic graft will be needed to fill the defect. (osref.org)
Eyes with corneal grafts may be vulnerable to infection because of exposed sutures, epithelial defects, graft hypoesthesia, and prolonged use of topical corticosteroids and eye drops with preservatives. (entokey.com)
We are for sure interested in offering this kind of corneal graft more often. (petseyes.cn)
A PKP procedure may be the best choice for patients who have certain eye diseases as well as those who have experienced rejection of a previous corneal graft. (cvpdaytoneyedoctors.com)
