Purpose: to develop a method of surgical treatment of patients with corneal ulcers of xerotic etiology and evaluate its efficacy in different time periods after operation. Materials and methods: 68 patients (86 eyes) with severe dry eye syndrome complicated by xerotic corneal ulcers were examined. In all patients, the ulcer defect was covered with conjunctiva and amniotic membrane. The operation was combined with an outer tarsorrhaphy and temporary blepharorraphy. Results: All 86 eyes (100%) achieved total closure of the ulcer defect, sealing of any perforation and maintaining of corneal transparency beyond the ulcer defect. Conclusion: Surgical closure of corneal ulcers with conjunctiva is an effective method of treatment of xerotic corneal ulcers. It could be recommended in patients with corneal perforation and tendency of descemetocele formation.

Abstract Purpose Demodex mites infestation, typically asymptomatic, is a problem for patients with weakened immune systems because it often takes the form of symptomatic, massive infection. The Demodex mites play an important role in the occurrence of a range of eye surface diseases such as Demodex blepharitis, Meibomian gland dysfunctions, conjunctivitis and corneal changes. The ocular infection is closely related to the systemic invasion. Our goal was to minimize infestation and alleviate the symptoms of massive demodicosis so as to prevent further damage to the cornea. Methods Our research note involves a 61-year old woman diagnosed with secondary Sjögren syndrome due to rheumatoid arthritis. On the background of the autoimmune disease, corneal perforation of the left eye occurred that was cured by surgery. Then during the follow-up visit the patient was found (microscopically) massively infected with Demodex mites and the developed symptoms were particularly severe. Results Adequate dry eye syndrome and massive demodicosis therapy significantly reduced the number of Demodex mites and improved the patient’s condition. Conclusion We would like to draw the attention of the physicians of different specialties that special care should be taken with respect to the therapy of dry eye syndrome and ocular demodicosis in patients with immunological disorders to achieve therapeutic success and avoid particularly dangerous consequences of these diseases.

Purpose. To report a case of severe corneal thinning secondary to dry eye treated with a tectonic Descemet stripping automated lamellar keratoplasty (DSAEK) and amniotic membrane graft.Methods. A 72-year-old man with a history of long standing diabetes mellitus type 2 and dry eye presented with 80% corneal thinning and edema on the right eye and no signs of infectious disease, initially managed with topical unpreserved lubrication and 20% autologous serum drops. Eight weeks after, the defect advanced in size and depth until Descemetocele was formed. Thereafter, he underwent DSAEK for tectonic purposes. One month after the procedure, the posterior lamellar graft was well adhered but a 4 mm epithelial defect was still present. A multilayered amniotic membrane graft was then performed.Results. Ocular surface healed quickly and reepithelization occurred over a 2-week period. Eight months after, the ocular surface remained stable and structurally adequate.Conclusion. Tectonic DSAEK in conjunction with multilayered amniotic graft may not only provide structural support and avoid corneal perforation, but may also promote reepithelization and ocular surface healing and decrease concomitant inflammation.

Background: Among numerous disorders treated by veterinary ophthalmology, therapies employed to solve corneal ulcers stand out. Amniotic membrane transplantation is an effective surgical technique for the treatment of complicated corneal ulcers in the dog, with highly satisfactory visual and cosmetic outcomes. However, in veterinary ophthalmology, reports on the use of the amniotic membrane and its corneal reconstructive potential are scarce. The objective of this work was to evaluate, for 21 days, the clinical aspects and the effectiveness of transplantation of canine amniotic membrane for corneal healing in two cases of complicated ulcers in dogs.Cases: Two Shih-Tzu dogs were diagnosed with complicated corneal ulcer. They underwent surgical treatment with the use of a glycerin-preserved canine amniotic membrane implant, which was secured on the cornea or the limbus. A surgical microscope at a magnification of 16x was used. The devitalized tissues at the periphery of the ulcer were excised, and multiple layers of amniotic membranes were sutured onto the cornea and near the limbus with interrupted absorbable suture. Protection of the canine amniotic membrane implants was performed with a scarified third eyelid flap, which was attached to the upper eyelid, and maintained for 14 days. During the first 14 days after the procedure, topical treatment with antibiotic eye drops was administered; protease inhibitors were also used. Antibiotics were used systemically for 10 days. Between days 14 and 21 after the transplantation procedure, protease inhibitors, corticosteroids, and lubricant were administered topically. Healing and clinical aspects were evaluated on days 0, 14, and 21. The parameters evaluated were blepharospasm, dazzle and direct pupillary reflexes, and consensual and threat responses. Corneal vascularization, hypopyon, synechia, opacity, and fluorescein dye penetration into the cornea were evaluated. The patient whose membrane was attached to the cornea was named COr, and the animal whose membrane was attached to the corneal limbus was named PLi. Blepharospasm and positive fluorescein test were detected only on the first day of the experiment; whereas, the dazzle and pupillary reflexes, as well as the consensual response, were present in both animals at all evaluated time points. Only COr exhibited hypopyon on day 0. Synechia was not observed in any of the animals at any of the time points. On the 21st day, COr exhibited deep vascularization and an opaque scar, while PLi exhibited only discrete vessels without blood perfusion, secondary to corneal repair.Discussion: A smooth operation of the central and peripheral ophthalmic system was maintained at all periods evaluated. The protection provided by the membrane contributed to corneal healing by reducing stimulation of nerve endings on the epithelium and stroma, and suppressing the blepharospasm reflex. The amniotic membrane used as an adjuvant has antimicrobial and anti-inflammatory properties, inhibits proteinases and mediators of inflammation, and exerts a mechanically protective effect. The corneal vascularization observed in both animals is related to the healing processes stimulated by filling the deep corneal lesions with the membrane. When used in addition to drug therapy, the amniotic membrane can inhibit postinflammatory neovascularization, fibroblast activity, collagen deposition, scarring, and opacifications. Accurate diagnosis, and correct therapeutic and surgical management, is fundamental for the successful treatment of corneal ulcers. In this work, canine amniotic membrane preserved in glycerin was used for the surgical treatment of complicated ulcers in dogs along with adequate clinical therapy. This was effective independent of the different anchorage techniques used, and led to satisfactory clinical results and short-term corneal healing.

Introduction: Pseudomonas aeruginosa (P. aeruginosa) is the leading cause of corneal ulcers in children 0 to 3 years of age compared to children in general. Case presentation: A two-months-old infant presented with whitish patches on the right eye two days before admission. A central corneal ulcer with a size of 7-mm x 7-mm accompanied by corneal thinning and melting was shown on the right cornea. It is was surrounded by greyish white creamy infiltrates. Corneal scraping showed Pseudomonas aeruginosa specimens. The cornea became perforate and crystalline lens extrusion was found at the day after intravenous ceftriaxone, levofloxacin eye drop, and cefazoline fortified eye drop administering. It might be caused by bacterial elastase and toxin which contributed to corneal damage. The patient was underwent a multilayer Amniotic Membrane Transplantation (AMT) combined with a pericardial patch graft due to corneal perforation. Two months post-AMT and pericardial patch graft the corneal perforation became entirely heal due to multilayer AMT, despite lysis of the pericardial patch graft. Corneal scar formation and reduction of vitreous opacity in ultrasound examination were shown. The patient was planned to undergo keratoplasty. Conclusions: Corneal ulcers due to Pseudomonas aeruginosa are highly destructive. The levels of infection, diagnostic, and therapeutic are still problems in pediatric patients. Lens extrusion and lysis of the pericardial patch graft are examples in this case. Keratoplasty is the definitive treatment for corneal ulcers with perforation; however, multilayer AMT combined with pericardial patch graft can be used as an alternative therapy to accelerate wound healing, reduce inflammation, and maintain the integrity of the eyeball.

Актуальность. Несмотря на многочисленные исследования этиопатогенеза синдрома «сухого глаза» (ССГ) и разработку новых методов его диагностики и лечения, проблема недостаточной эффективности терапии ССГ остается актуальной и в некоторых случаях связана с наличием сопутствующей глазной патологией. В частности, к заболеваниям, сопровождающимся симптомами, характерными для ССГ, относится хронический периферический увеит (ХПУ). Цель. Изучить особенности течения ССГ на фоне хронического периферического увеита. Материал и методы. Клиническое исследование проведено среди 78 пациентов (156 глаз) в возрасте от 18 до 60 лет, страдающих ХПУ. В зависимости от клинической формы основного заболевания больные были разделены на 3 группы: 1-я группа – ползучая периферическая дистрофия (19 пациентов, 38 глаз), 2-я группа – белая сетчатка с/или без давления (42 пациента, 84 глаза), 3-я группа – пристеночные экссудаты (17 пациентов, 34 глаза). В ходе осмотра проводили сбор жалоб и анамнеза, визометрию, бесконтактную тонометрию, биомикроскопию переднего отрезка обоих глаз, тест Ширмера I, пробу Норна, бинокулярную офтальмоскопию со склерокомпрессией. Результаты. У пациентов 1-й группы ССГ легкой степени наблюдался в 89,4% случаях, в структуре жалоб преобладали зрительный дискомфорт – 34,2%, ощущение «сухости» – 26,3%. У пациентов 2-й группы в 83,3% выявлялось легкое течение ССГ с преобладанием чувства зрительного дискомфорта и «сухости» – 29,7% и 23,8% соответственно. У пациентов 3-й группы ССГ легкой степени отмечался в 64,7% с преобладанием жалоб на зрительный дискомфорт – 41,2%. При этом у пациентов 3-й группы чаще по сравнению с пациентами 1-й и 2-й групп, выявлялись жалобы на слезотечение – 17,2%, покраснение глаз – 32,3%, «затуманивание зрения» – 20,6%. При биомикроскопии переднего отрезка во всех 3 группах обнаруживались тусклость конъюнктивы век и переходных складок – 67,8%, нависание конъюнктивы складками над задним ребром нижнего века – 83,3%. У пациентов 3-й группы наиболее часто по сравнению с 1-й и 2-й группами выявлялись симптомы ССГ в виде наличия скудного вязкого отделяемого в конъюнктивальной полости – 14,7%, «вялая» гиперемия конъюнктивы глазного яблока – 41,7%. Снижение суммарной слезопродукции наблюдалось у всех пациентов с ХПУ, при этом в 3-й группе данный показатель был ниже в 1,6 раза, чем во 1-й и 2-й группах. Нестабильность прекорнеальной слезной пленки, полученной в результате пробы Норна, определялась до 8 сек в 1-й и 2-й группе и до 6 сек в 3-й группе пациентов. Выводы. Тяжесть течения ССГ на фоне ХПУ в значительной степени зависит от активности воспаления хориоретинальных структур вблизи зубчатой линии. Наиболее выраженные клинические проявления ССГ наблюдаются при ХПУ в виде «пристеночных экссудатов». Результаты исследования могут служить основой для изучения особенностей течения ССГ на фоне хронического интраокулярного воспаления и разработки дифференцированных методов лечения.
