  https://www.eyeworld.org/2007/treating-hsv-keratitis/

  Once they delineate the type of HSV keratitis the patient has, clinicians must decide on the most effective use of antiviral medications. This may mean a choice of oral versus topical antiviral medications, combining antivirals with corticosteroids when appropriate, and prescribing antiviral medications as prophylaxis indefinitely or before surgery. […] Some research, such as that from the HEDS investigators, indicates a role for oral antivirals to prevent these recurrences. […] The HEDS investigators found that long-term prophylaxis with oral antivirals can reduce recurrences by 50%. […] Dr. Chodosh recommends long-term oral acyclovir for patients with 1) multiple occurrences of HSV that each require corticosteroids, 2) recurrent inflammation with scarring or neovascularization that approaches the visual axis, 3) more than one episode of necrotizing keratitis, or 4) a history of herpetic eye disease and a corneal transplant.

• #24 Herpes Simplex Virus (HSV) Keratitis Treatment & Management: Approach Considerations, Infectious Epithelial Keratitis, Stromal Keratitis

  https://emedicine.medscape.com/article/1194268-treatment

  The major difficulties in treating herpetic keratitis relate to the tendency for recurrences and to the management of stromal disease. In its latent form, HSV can be present in the cells of the cornea and in the central connections of the trigeminal nerve, particularly in the trigeminal ganglion. Disturbance of host defense results in reactivation of the virus, its subsequent passage centrifugally along the nerve, and resultant shedding from the nerve endings. Corneal lesions occur when the balance between latency and reactivation is disturbed, such as during febrile illnesses, during menses, or on exposure to sunlight. Once trigger factors are identified, they need to be avoided. […] Using 400 mg of acyclovir once or twice daily as prophylaxis can reduce the incidence of recurrence. This is recommended for patients with recurrent stromal disease or more than 2 episodes of epithelial disease per year.

  Preventing Post-LASIK Keratitis […] For prophylaxis against post-LASIK infectious keratitis, surgeons need to implement several steps. Preoperatively, all patients considering refractive surgery should have a thorough examination of their eyelids and lacrimal apparatus. Treating infectious lid disease prior to LASIK with hot compresses and a topical antibiotic ointment applied three times daily to the lid margin may decrease the risk of a bacterial keratitis. […] A 10 betadine solution applied to the eyelids prior to cataract surgery has been shown to decrease the incidence of endophthalmitis postoperatively, and this technique is recommended by many clinicians for LASIK. Proper methods of sterilization can prevent the use of contaminated instruments. Because several epidemics of atypical mycobacteria have been associated with the use of nonsterile water to clean instruments or the use of ice during LASIK surgery, all fluids applied to the eye before, during, and after LASIK should be disinfected.

• #37 CRSToday | Preventing Post-LASIK Keratitis

  https://crstoday.com/articles/2007-jan/crst0107_12-php

  Antibiotic prophylaxis for LASIK should provide a broad-based spectrum of coverage with an emphasis on gram-positive organisms. Ophthalmologists should choose a nontoxic antibiotic to promote epithelial healing and provide coverage against atypical mycobacteria. Finally, the appropriate antibiotic will penetrate effectively into the cornea and achieve therapeutic levels in the middle stroma. Fourth-generation fluoroquinolones (gatifloxacin 0.3 and moxifloxacin 0.5) for the antibiotic prophylaxis against infection following LASIK and PRK are recommended, because they are best suited to meet the aforementioned criteria.

  Active HSV keratitis is an absolute contraindication to laser corneal refractive surgery (ie, LASIK, PRK) or other corneal procedures (collagen cross-linking). Inactive keratitis or a history of previous HSV disease also is considered a relative contraindication. Recurrence of HSV keratitis after refractive surgery is a well-known complication. However, case reports have documented good refractive surgery outcomes in selected patients whose keratitis has been inactive for at least 1 year and in whom perioperative systemic antiviral prophylaxis is used. […] Ongoing research into HSV vaccination is being conducted. While nearly all developmental vaccines are targeting HSV-2 and genital herpes, evidence suggests that these vaccines may offer cross-protection in preventing ocular HSV-1 infections. However, concerns remain that a boost in immune response to HSV after vaccination may exacerbate herpetic stromal keratitis.

  Corneal toxicity with high-dose cytarabine is a well-established risk of therapy. Routine prophylaxis with eye drops, usually topical corticosteroid drops, is an established part of high-dose cytarabine treatment protocols. Without topical corticosteroid prophylaxis, incidences of keratoconjunctivitis have been reported in 85% to 100% of cases; the occurrence of clinically significant symptoms with the use of prophylaxis is reported in 8% to 16% of cases. […] Prophylaxis is generally not recommended at doses 1000 mg/m2. Suggested prophylaxis is corticosteroid eye drops; however, other agents and combinations have been used successfully. These include a variety of preparations, including tear replacement solutions and topical, nonsteroidal anti-inflammatory drops. Every 4- or 6-hour administration on a strict schedule appears to provide the most benefit, and drops should be continued at least 48 hours after the last cytarabine dose. The mechanism of conjunctivitis prevention is unclear, but may rely on a decreased replication rate induced by corticosteroids impacting DNA replication in corneal cells. An additional mechanism of action may be a diluting effect on the cytarabine concentration; 1 trial showed benefits achieved from frequent use of artificial tears. […] Unless a deoxycytidine product is developed and proven successful, the information currently available would support the addition of an NSAID eye drop to corticosteroids for high-risk or symptomatic patients. Additional research is clearly warranted in this area.

  Potentially vision-threatening ocular surface disorders have been found in over 50% of intensive care unit (ICU) patients. […] Appropriate eye care protocols in the ICU can prevent or reduce the severity of ocular complications. […] In summary, ocular protection varies across ICUs, with some having no protocols in place for ocular protection. […] These findings suggest that suboptimal eye care to prevent exposure keratitis is provided in Ontario ICUs and that evidence-based protocols should be developed and implemented.

  If increased corneal exposure is detected, several preventive measures can be done to prevent keratitis. Artificial eye drops and eye ointments may be used to keep the eyes moist. Since frequent use of eye drops with preservatives can promote inflammation, it is better to choose preservative free artificial tear drops and lubricating eye drops. Bandage silicone hydrogel or scleral contact lens may be used to protect cornea. But, risk of infection is more with bandage contact lens use. Moisture goggles may also be used to protect cornea. Temporary or permanent tarsorrhaphy may be indicated to treat lagophthalmos. Gold weights can be inserted into the upper eyelid to treat facial nerve palsy.

  Wearing proper eye protection and safeguarding the eyes against the sun and UV radiation is key to preventing photokeratitis. […] Sunglasses and snow goggles that block or absorb at least 99% of ultraviolet rays should be worn when the eyes are exposed to sun or snow. Eyewear designed to wrap around the sides of the head or those with side shields are ideal when spending time outdoors. Wearing a hat with a visor or wide brim can help further protect the eyes from UV radiation. […] Wearing a welders helmet helps protect the eyes from UV radiation produced during arc welding. Full-face shield helmets with adjustable-shade levels are needed for sufficient protection. […] UV-absorbing contact lenses are available for individuals who spend considerable time outdoors or in environments affected by ultraviolet light.

  Ultraviolet lights potential in ocular care extends beyond structural reinforcement to antimicrobial applications, especially for microbial keratitis. […] Given these challenges, non-pharmacologic strategies such as UV light have gained attention for their antimicrobial properties, with UVC emerging as a promising optiona novel, non-invasive and resistance-independent treatment. […] Given its broad antimicrobial spectrum and resistance-independent mechanism, UV therapy has gained interest in ophthalmology as a potential treatment for infectious diseases like MK. A recent comprehensive review of UV treatments for superficial skin and ocular infections concluded that UVC therapy is a promising adjunct or alternative to conventional antibiotics. […] UVC therapy has the potential to become a gold standard treatment for MK, improving patient outcomes and reducing the global burden of corneal blindness. Future research should focus on piloting the in vivo use of UVC in patients to assess its safety and efficacy, optimising dosing protocols and eventually undertaking large-scale clinical trials.

  The present study uses, for the first time, CTC stain analyzed by flow cytometry to establish Acanthamoeba viability demonstrating its usefulness and complementarity with the traditional stain, Trypan Blue. […] Artelac Splash, with no preservatives, and Optava Fusion, with Purite, have not shown any amoebicidal activity. […] On the contrary, promising results presented by Ocultect, with BAK, open up a new possibility for Acanthamoeba keratitis prophylaxis and treatment although in vivo studies should be carried out. […] In view of these results, we must highlight the importance of the data obtained with both methods used to investigate the viability of Acanthamoeba trophozoites. […] Finally, in this study, only Oculotect was demonstrated to have an important and durable amoebicidal effect on Acanthamoeba trophozoites. […] This characteristic means that it is not advisable to use this artificial tear concomitantly with soft lenses. […] Nevertheless, studies in corneal models or even in patients are needed to establish the in vivo amoebicidal effect of this kind of artificial tear formulation.
