Epithelium healing

Broad-spectrum antibiotic drops, such as 0.3% tobramycin, 0.3% ciprofloxacin, or the newer generation fluoroquinolones, moxifloxacin or gatifloxacin, may be instilled four times daily to prevent secondary infection as the epithelium heals. A broad-spectrum ophthalmic ointment, such as 0.3% ciprofloxacin, may be instilled into the conjunctival sac at bedtime for prophylaxis. In more pronounced cases, pupillary dilation and cyclo-plegia with a long-acting agent such as 5% homatropine may help to relieve pain from associated ciliary spasm. 

Immediate treatment with topical fluoroquinolone eyedrops every 30-60 min, with cycloplegics two to three times a day for first day. Fluoroquinolone ointment at night. Patient followed on daily basis until epithelium healed, then taper therapy.

The animals treated with 200, 400, and 800 lU A showed a healing effect of vitamin A on the cornified vaginal epithelium as early as 2 days after starting the experiment. In the smear of all concentrations, almost exclusively leukocytes — indicating a successful healing and mucosal regeneration — with only sporadic epithelial cells and squamous cells... 

Benign ocular bums are grade 1 and grade 2 ocular bums. They evolve toward healing within 10 days or so. In this case, the epithelium of the cornea centrip-etally and gradually grows back. Treatments aim to prevent infectious complications and to support cicatrization.

Qualitative in-life biomarkers that are characteristic of chronic exposure to white phosphorus include progressive destruction of the jaw bones (phossy jaw), brittleness of long bones, and poor healing of oral cavity lesions including tooth sockets after tooth extraction (see Section 2.2 for details). In-life biomarkers that are probably shared with other toxic compounds include increased permeability of capillary walls and impaired microcirculation. Postmortem qualitative biomarkers include hyperkeratosis of the epithelium of the oral mucosa and lesions of the capillary walls (see Section 2.2 for details). Hyperkeratosis is a microscopic morphological finding that can be seen in biopsy material from a living patient or from an autopsy and is seen in association with phosphorus intoxication. 

These kinds of wounds will be closed in the secondary healing processes, where the formation of granulation tissue first takes place. Covering with epithelium is the final stage of wound healing. Often such secondary healing processes take a long time and require a lot of material [ 126]. 

The toxieity of both neat and vapor exposures of SM to the eye is highly predictable. After a time period of no symptoms, laerimation begins and quickly progresses to eonjunetivitis, pain, blepharospasm, and photophobia. Comeal edema follows rapidly as a result of the loss of the epithelium, whieh allows water to enter the stroma from the preeomeal tear film (Slatter, 1990). By 24 h after exposure, it is not unusual to see a 100 to 300% increase in comeal thiekness evident by a substantial increase in opacification. Fluorescein staining at 24 h will reveal ulcers that may eover a majority of the eomeal surface. By 48 h, evidence of healing is seen, and by 96 h, it is not imusual to have... 

Introduced into ophthalmic practice in 1942, polyvinyl alcohol (PVA) is a water-soluble viscosity enhancer with both hydrophilic and hydrophobic sites. A common concentration used in ophthalmic preparations is 1.4%. PVA is useful in the treatment of corneal epithelial erosion and dry eye syndromes because it is nonirritating to the eye and actually appears to facilitate healing of abraded epithelium. It is used also to increase the residence time of drugs in the tears, aiding ocular absorption.
