  https://pmc.ncbi.nlm.nih.gov/articles/PMC5710829/

  Infectious keratitis is a major global cause of visual impairment and blindness, often affecting marginalized populations. Proper diagnosis of the causative organism is critical, and while culture remains the prevailing diagnostic tool, newer techniques such as in vivo confocal microscopy are helpful for diagnosing fungal keratitis and Acanthameoba. Next generation sequencing holds the potential for early and accurate diagnosis even for organisms that are difficult to culture by conventional methods. […] Topical antibiotics remain the best treatment for bacterial keratitis, and a recent review found all commonly prescribed topical antibiotics to be equally effective. However outcomes remain poor secondary to corneal melting, scarring and perforation. Adjuvant therapies aimed at reducing the immune response responsible for much of the morbidity associated with keratitis include topical corticosteroids.

• #1 Keeping up with Keratitis

  https://www.reviewofoptometry.com/article/keeping-up-with-keratitis

  Microbial keratitis is a generally painful and sight-threatening condition often associated with ocular trauma, ocular surface disease and contact lens wear. Traditional first-line therapy of infectious ulcers involves the use of empiric treatment with topical antibiotics. The role of microbial culture remains perplexing for many practitioners who wonder if they should withhold therapy until results are in, and the use of certain adjunctive therapies, such as topical corticosteroids, is controversial. […] When initiating treatment of keratitis, corneal infiltrates must first be classified as sterile or infectious in nature. Infectious keratitis. When you see stromal infiltrates in the presence of epithelial disruption, particularly in cases of bacterial disease, you’re quite likely dealing with an infectious etiology. Prompt empiric treatment is generally necessary when culture and/or sensitivity testing is unavailable or hasn’t yet been performed. The regimen should consist of topical broad-spectrum antibiotics, such as fluoroquinolones or fortified aminoglycosides, with a cephalosporin or vancomycin.

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

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

  Since most cases of herpes simplex virus (HSV) epithelial keratitis resolve spontaneously within 3 weeks, the rationale for treatment is to minimize stromal damage and scarring. Gentle epithelial debridement may be performed to remove infectious virus and viral antigens that may induce stromal keratitis. Antiviral therapy, topical or oral, is an effective treatment for epithelial herpes infection. […] Treatment options for primary ocular herpes infection include the following: Ganciclovir ophthalmic gel 0.15% – 5 times daily; Trifluridine 1% drops – 9 times daily; Vidarabine 3% ointment – 5 times daily; Oral acyclovir 400 mg – 5 times daily for 10 days; oral acyclovir is the preferred treatment in patients unable to tolerate topical medications and with good renal function; Valacyclovir 500mg – 3 times daily; Famciclovir 250 or 500mg – 3 times daily; A cycloplegic agent may be added to any of the above regimens for comfort from ciliary spasm.

• #1 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. 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. […] 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.

Concomitant ocular issues causing additional irritation and inflammation such as dry eye, environmental allergies, ocular rosacea, blepharitis, meibomian gland dysfunction, herpes infections, and contact lens associated irritation and inflammation, should also be addressed. […] Topical lubrication with preservative-free artificial tears, gels, and ointments […] Prescription anti-inflammatory eye drops […] Oxervate (Cenegermin) is an FDA approved topical recombinant nerve growth factor. It is an eye drop which is instilled in the affected eye(s) 6 times each day at 2-hour intervals for 8 weeks. […] Compounded topical insulin in the form of eye drops is an emerging area of research showing promise in treating dry eye disease, Meibomian gland dysfunction, ocular rosacea and blepharitis, collectively known as ocular surface diseases (OSD). These conditions involve inflammation, dryness, and damage to the cornea and conjunctiva (the ocular surface), lacrimal and Meibomian glands. Insulin has been found to have beneficial effects due to its anti-inflammatory and tissue-repairing properties, its ability to stimulate tear production and to improve corneal nerve function. Insulin eye drops are believed to promote cell growth and repair of the surface of the eyes, the lacrimal glands and the Meibomian glands, and to accelerate corneal healing, especially in cases of persistent epithelial defects (PEDs) and neurotrophic keratitis (NK). Additional studies suggest topical insulin can help restore corneal nerve function, which is crucial to supporting the health of the cornea and ocular surface.

  The large number of active antimicrobial drugs available to the treating clinician offers the patient with bacterial keratitis a greater chance for cure with less drug-related toxicity while providing alternative choices despite the continuing emergence of drug-resistant pathogenic organisms. […] Although some organisms continue to be predictably susceptible to selected antimicrobial agents, the development of clinically important resistant isolates is common because of the high selective pressures applied by intense antibiotic usage. […] The response of bacterial keratitis to antibiotic therapy must be monitored with frequent clinical observation. The principal end points of treatment are re-epithelialization and nonprogression of stromal infiltrates.

  Irregular astigmatism resulting from chronic stromal keratitis may be correctable with rigid, gas-permeable contact lenses. Patients with visually significant corneal opacities or corneal perforations may require keratoplasty for visual rehabilitation. […] Although an uncommon occurrence, progressive necrotizing stromal keratitis and impending corneal perforation may be better managed with tissue glue and bandage contact lens before considering keratoplasty. […] If possible, a small descemetocele or perforation in an inflamed eye initially may be managed with tissue adhesive, a bandage contact lens, and/or amniotic membrane transplantation. Corneal transplantation ideally should be deferred until the eye is less inflamed. […] The prognosis for a successful graft approaches 80% in eyes without inflammation prior to surgery. Prophylactic oral antiviral therapy following penetrating keratoplasty reduces recurrent ocular HSV disease and graft rejection episodes and improves graft survival. Most surgeons use a systemic antiviral agent (eg, acyclovir 400 mg bid) for at least 6-12 months after penetrating keratoplasty.

  Depending on the laboratory reports, treatment will be started. Antibiotics, antifungals or antivirals are started in the form of tablets and eye drops depending on the causative agent. In cases of large or severe corneal ulcer (keratitis), fortified eye drops are started which are prepared from available injectable preparations. This is accompanied by oral pain killers, cycloplegics eye drops which relieves pain, anti glaucoma eye drops to reduce the intraocular pressure and artificial tears. The frequency depends on the size of the ulcer. Corticosteroids are strictly prohibited in cases of fungal corneal ulcer (keratitis). However, they can be considered in other types of ulcers at a later stage under extreme caution and supervision. […] In case of a small perforation, tissue adhesive glue is applied over the perforation under sterile conditions followed by a bandage contact lens to seal the perforation. Bandage contact lenses are also used in cases of recurrent epithelial erosions for better healing. Patients who have eyelid deformities, leading to an ulcer, need corrective surgeries. If the corneal ulcer (keratitis) is due to an eyelash growing inward, the offending lash should be removed together with its root. If it grows back in an abnormal manner, the root may have to be destroyed using a low-voltage electrical current. In cases of improper or an incomplete lid closure, a surgical fusion of the upper lid and lower lid is done. Small perforations are also treated with patch grafts which means taking a full thickness or partial thickness graft from the donor cornea and anchoring it over the perforated site.

  What is the treatment? […] Antiviral eye gel a course of eye gel (ganciclovir) is the treatment for most cases. […] Antiviral tablets a 7-day course of antiviral tablets (e.g. aciclovir, valaciclovir) may be required in severe and/or recurrent cases. […] Steroid eye drops sometimes these are used to reduce inflammation and minimise scarring. […] Advice for contact lens wearers – contact lenses should not be worn until all symptoms have gone. […] If you have HSV keratitis, it can become a recurrent problem. […] If you keep getting recurrent infections, your eye doctor might recommend that you take daily antiviral tablets to help prevent infections. […] Severe or repeated episodes can result in scarring of the cornea, which can cause blurred vision. […] Each time you have an episode you should see an eye doctor as soon as possible so they can check your eye and give you the correct medication.

  Keratitis is inflammation of the cornea, a clear and transparent covering over the iris and pupil. […] Diagnosis is usually based on clinical findings and slit-lamp examination. Keratitis is an emergent disorder that can lead to irreversible vision loss left untreated. […] Treatment for epithelial HSV keratitis includes topical trifluridine solution or ganciclovir 0.15% gel. […] Treatment: oral acyclovir, valacyclovir, or famciclovir. […] Treatment includes topical antiseptic (e.g., chlorhexidine) with propamidine. […] Treatment: antimycotics such as natamycin, nystatin, amphotericin B. […] Treatment: patient briefing, antibiotic eye ointment, immobilization, oral analgesics. […] Treatment: early stage: artificial tears; late stage: prophylactic antibiotic drops; tarsorrhaphy; amniotic membrane transplantation and conjunctival flap.

  For example, a patient with HSV stromal keratitis may receive steroids to reduce inflammation and remain on oral antivirals while they are using the steroids, to help reduce the risk of recurrence potentially triggered by steroid use, Dr. Holland said. […] However, without steroid treatment, theres a greater risk for corneal scarring. […] Dr. Mah also sees residents and community practitioners struggle with when to administer steroids in herpetic patients. […] Still, Dr. Mah agreed with Dr. Holland that the careful use of steroids combined with oral antivirals is the best treatment course in patients with HSV stromal keratitis. […] Some research, such as that from the HEDS investigators, indicates a role for oral antivirals to prevent these recurrences. […] Theres good evidence from the HED study that shows oral antiviral pills, such as the use of long-term acyclovir, can significantly reduce the risk for recurrences.

• #2 Acanthamoeba Keratitis, Pathology, Diagnosis and Treatment

  https://www.mdpi.com/2076-0817/10/3/323

  Acanthamoeba keratitis is an unusual corneal infection that is recently increasing in frequency and is often contracted by contact lens wearers, someone who experienced recent eye trauma, or someone exposed to contaminated waters. […] Once diagnosed, it is usually treated with an antimicrobial combination therapy of biguanide and aromatic diadine eye drops for several months. […] The Acanthamoeba can exist in an actively mobile trophozoite form or a dormant cyst form which is highly resistant to drugs. Biguanides and aromatic diamidines are effective antimicrobial agents for killing the pathogen but must be given together to overcome drug resistance. […] Treatment is usually administered through the form of topical eye drops, given every hour initially for the first few days. […] Multiple authors recommend continuing treatment for several months to prevent reinfection or recrudescence of the disease.

  The use of corticosteroids to decrease the intense inflammation that occurs in AK is controversial because of the disadvantage of potentially promoting encystment and increasing trophozoites. […] If the recommended treatment of biguanides and aromatic diamidines fail, and the infection has progressed to an advanced stage, then a therapeutic corneal transplantation or various keratoplasties can be the last resort of treatment. […] While chlorhexidine, PMHB, and propamidine are currently the recommended agents of AK treatment, a few reports have employed collagen cross-linking using riboflavin and UV lights as a successful adjunct strategy for the conventional topical therapy.

  Aggressive eradication of infection is the most important step in treating infectious keratitis, which may involve around-the-clock use of antibiotic eye drops. […] Viral keratitis is best treated with use of systemic antiviral medication, along with topical antiviral drops or ointment, and addition of corticosteroid drops once surface disease is resolved. […] Fungal keratitis is treated in a similar fashion, however, corticosteroids should never be used to help resolve inflammation or scarring in these cases. […] Non-infectious keratitis is best treated with topical corticosteroid, with close observation when there is significant thinning to make sure the wound does not worsen. […] Severe disease, especially that driven by known autoimmune disease, may require oral or intravenous corticosteroids or immunomodulatory therapy.

  Note: Topical steroids arent used in cases of corneal melting because weve found they may accelerate it. […] A few other treatments are needed to counteract prednisone side effects. Bactrim Double Strength is initiated to prevent opportunistic infection of the lungs. […] Lastly, in cases with severe corneal thinning, a shield at bedtime protects the patient from accidentally pushing on their eye and perforating the cornea. […] The most acute complication to prevent is perforation of the cornea. In addition to starting steroids, you can either glue or resect the conjunctiva to avoid a surgical intervention such as corneal tectonic graft or full corneal replacement. […] Cyanoacrylate glue (off label). Its thought that this glue prevents further melting and stabilizes the cornea by acting as a physical barrier to the inflammatory mediators entering into the cornea.

  Even in mild Stage 1 disease, there is potential for vision loss, and if left undiagnosed and untreated, neurotrophic keratitis can progress quickly from mild to moderate to severe. In the moderate to severe stages, patients are at risk not only for profound vision loss but also for severe sequelae, such as corneal scarring and corneal perforation. […] Similar to dry eye patients, patients with neurotrophic keratitis will vary and their treatment will require a dynamic approach. One of the universal concepts is to remove any additional insults to the ocular surface, such as topical drops that contain preservatives. […] For Stage 1 neurotrophic keratitis, the recommendation is to lubricate the cornea with artificial tears or ointments and avoid topical medications that contain preservatives, which can be toxic. Treatment for Stage 2 may involve tarsorrhaphy or a conjunctival flap. Treatment for Stage 3 may require a therapeutic contact lens and/or amniotic membrane transplantation (AMT). A corneal perforation will necessitate corneal gluing, AMT, conjunctival flap, or keratoplasty.

  PACK-CXL holds promise, but more evidence is needed from ongoing research. […] Overall, evidence on the efficacy of this procedure known as Photoactivated Chromophore for Infectious Keratitis (PACK)-CXL is favourable. […] Still, it is an area of ongoing evolutionthe procedure is not without potential complications, and there remains a need for randomised controlled clinical trials using standardised outcome measures to determine the place of PACK-CXL in clinical practice, according to Rohit Shetty MD, PhD. […] What is clear, however, is safe and effective PACK-CXL can address an unmet need, considering the prevalence and cost burdens of IK and the potential for blindness with failed antimicrobial therapy, he said. […] A systematic review and meta-analysis published in 2019 found PACK-CXL and antimicrobial therapy accelerated corneal healing compared to antimicrobial therapy alone.
