Purpose: To develop a method for treatment of advanced purulent corneal ulcers in eyes with neurotrophic keratitis that developed as a complication of intracranial pathological processes or brain surgeries., Material and Methods: The study involved 13 patients (14 eyes) that underwent combined surgery - keratoplasty, autoconjunctival flap covering, partial tarsorrhaphy performed simultaneously. Before and after the surgery, patients received frequent instillations of antimicrobial agents and autologous serum., Results: The organ of vision was preserved in all patients, visual function - in 50% of cases, it improved in 35.7% of cases from 0.07±0.05 to 0.26±0.11. Lagophthalmos has decreased from 6.11±0.99 to 2.78±0.62 mm., Conclusion: Patients with intracranial lesions and complicated by neurotrophic keratitis and lagophthalmos often develop advanced severe and progressive corneal purulent ulcers, which seldom respond to the most active conservative therapy. Simultaneous surgery that includes keratoplasty, auto conjunctival flap covering and partial superficial tarsorrhaphy is an effective treatment option that helps preserve visual function in such eyes.

Purpose: To investigate the toxic effects of frequent instillations of anti-infective solutions (antibiotic eye drops - 0.3 and 1.4% tobramycin, 0.5% levofloxacin and 0.5% moxifloxacin; antiseptic eye drops - 0.05% pyloxidine and 0.025% chlorhexidine; antifungal drug - 2 mg/ml fluconazole solution) on ocular tissues., Material and Methods: The study was conducted on 21 Wistar rats (42 eyes) using method of semi-fine sections., Results: The majority of antibiotics and antifungal agents do not cause toxic reactions in rats` eyes when instilled with frequent regimen with the exception of 'fortified' 1.4% tobramycin and pyloxidine solutions, which caused a decrease in corneal endothelial cells density and formation of fibrovascular tissue in the anterior chamber., Conclusion: Frequent instillations of antimicrobial drug solutions is a safe method for the treatment of purulent corneal ulcers and purulent keratitis. The exceptions were solutions of 'fortified' 1.4% tobramycin and piloxidine (vitabact).

Objective: The study objective was to develop a method for surgical treatment of advanced purulent corneal ulcer in the setting of neuroparalytic keratitis developed after acoustic neuroma removal and strokes., Material and Methods: The study included 12 patients (13 eyes). All patients underwent single-step keratoplasty, conjunctival autografting, and partial permanent tarsorrhaphy., Results: The eye as an organ was spared in 100% of cases; vision was spared in 50% of cases and improved, from 0.09±0.05 to 0.21±0.13, in 29% of cases. Lagophthalmos was reduced from 5.86±1.35 to 3.01±0.75 mm., Conclusion: Patients with intracranial lesions complicated by neuroparalytic keratitis often develop progressive purulent corneal ulcers. The simultaneous use of surgery, including keratoplasty, conjunctival autografting, and partial (external) tarsorrhaphy, is an effective treatment that can preserve the visual function of these eyes.

In recent years, collagen cross-linking (CXL) of the cornea has acquired a new usage - in the treatment of infectious keratitis and corneal ulcers. This review was aimed at compiling the previously published data and assessing the effectiveness of the method.

Aim: to develop a surgical approach to the treatment of purulent corneal ulcer in eyes with neurotrophic keratitis with lagophthalmos after auditory neuroma removal or stroke., Material and Methods: A total of 12 patients (13 eyes) have been managed. All received combined surgery that included simultaneous keratoplasty, autoconjunctivoplasty, and permanent partial tarsorrhaphy., Results: Ocular integrity was preserved in all cases, and also vision - in half of them. In 29% of cases, visual acuity increased from 0.09±0.05 up tо 0.21±0.13. Lagophthalmos decreased from 5.86±1.35 mm down to 3.01±0.75 mm., Conclusion: Patients with intracranial lesions complicated by neurotrophic keratitis and lagophthalmos often develop progressive purulent ulcers of the cornea. One-step keratoplasty, autoconjunctivoplasty, and permanent partial tarsorrhaphy is an effective treatment that can help preserve visual function in such eyes.

The outcomes of keratitis in lagophthalmos occurring due to various causes despite therapeutic measures are generally poor. The influence of factors, such as drying of the cornea, impairment of its trophism, and infection, leads to the development of rough leukomas, and occasionally to eye death due to occurring endophthalmitis. The paper describes a clinical case of deep trophic central corneal ulcer on the single seeing eye with lagophthalmos, as well as ulcer treatment by the authors' procedure, by simultaneously affecting both elements of the pathology (lagophthalmos and trophic ulcerative keratitis of central localization) and creating an artificial pupil. This allows one to increase visual acuity, to cure keratitis, and to close a palpebral fissure.
