As with other topically administered ophthalmic drugs, VEXOL® 1% (rimexolone ophthalmic suspension) is absorbed systemically. Studies in normal volunteers dosed bilaterally once every hour during waking hours for one week have demonstrated serum concentrations ranging from less than 80 pg/mL to 470 pg/mL. The mean serum concentrations were approximately 130 pg/mL. Serum concentrations were at or near steady state after 5 to 7 hourly doses. After decreasing the dosing frequency to once every two hours while awake during the second week of administration, mean serum concentrations were approximately 100 pg/mL.

Patients tend to present with a rapid onset of pain, photophobia, redness and reduced vision. Bacterial corneal ulcers typically have a variably sized defect in the corneal epithelium which can be highlighted using fluorescein dye. In addition there is usually a pale inflammatory infiltrate present in the deeper corneal tissue; this may be visible as a whitish opacity using a pen torch to illuminate. Common causative agents include Staphylococcus aureus, Streptococcus pneumonia and pseudomonas aeruginosa, the latter being the most frequent organism in contact lens wearers.

Proper diagnosis is essential for optimal treatment. Bacterial corneal ulcer require intensive fortified antibiotic therapy to treat the infection. Fungal corneal ulcers require intensive application of topical anti-fungal agents. Viral corneal ulceration caused by herpes virus may respond to antivirals like topical acyclovir ointment instilled at least five times a day. Alongside, supportive therapy like pain medications are given, including topical cycloplegics like atropine or homatropine to dilate the pupil and thereby stop spasms of the ciliary muscle . Superficial ulcers may heal in less than a week. Deep ulcers and descemetoceles may require conjunctival grafts or conjunctival flaps, soft contact lenses , or corneal transplant . Proper nutrition, including protein intake and Vitamin C are usually advised. In cases of Keratomalacia, where the corneal ulceration is due to a deficiency of Vitamin A, supplementation of the Vitamin A by oral or intramuscular route is given. Drugs that are usually contraindicated in corneal ulcer are topical corticosteroids [2] and anesthetics - these should not be used on any type of corneal ulcer because they prevent healing, may lead to superinfection with fungi and other bacteria and will often make the condition much worse.

Uveitis is another complication of herpes infections that may present after the initial visit. Ensure that the patient is taking the maximum oral antiviral therapy with good compliance. If uveitis appears, there can be a rapid development of inflammation that requires aggressive treatment. A loading dose of topical Pred Forte (prednisolone acetate 1%, Allergan) given every 15 minutes for a few hours, followed by a week of hourly dosing, is a reasonable start. Cycloplegia with a long-acting agent, such as homatropine 5%, is necessary. As with potential corneal scarring, seek subspecialty consultation if herpes associated uveitis is slow to resolve.
