RESUMO

PURPOSE: To evaluate the safety and the effectiveness of our novel penetrating keratoplasty for infectious keratitis. METHODS: Retrospective, noncomparative, interventional case series of patients with infectious keratitis who received the novel penetrating keratoplasty technique were analyzed. A prepared plastic sheet was located between the diseased cornea and iris-lens diaphragm. After the diseased lesions were removed, the graft was positioned on the plastic sheet and sutured to the recipient bed. The plastic sheet was pulled out from the anterior chamber before the all interrupted sutures were placed. The intra- and post-operative complications, the outcome of the graft and the number of corneal endothelial cells were analyzed. RESULTS: A total of 82 eyes of 82 patients was included. The mean follow-up period was 29 ± 16 months (range from 13 to 45 months). No intraocular content extrusion, simultaneous cataract extraction and suprachoroidal hemorrhage occurred. Direct contact between the infectious cornea and the graft was successfully avoided. Greater than expected endothelial cell reduction or complications were not found. CONCLUSIONS: This modified technique effectively prevents the extrusion of intraocular contents while avoiding the direct contact with donor endothelium during the procedure. The occurrence rate of complications such as endothelial cell loss is not higher than the conventional methods.

RESUMO

OBJECTIVES: To summarize the clinical manifestations, microbiological profile, treatment, and prognosis of corneal infections after different keratorefractive surgery. METHODS: To obtain relevant studies, English-language databases, including PubMed, Ovid Embase, Web of Science, and CLNAHL, were searched from January 1979 to March 2022. The fundamentals of the literature, clinical characteristics, pathogens, and treatments were retrieved for each included article. RESULTS: Eighty-four studies involving 306 infectious eyes were included in this review. Risk factors of potential infection included a history of blepharitis, contact lens usage, and contaminated surgical instruments. The mean onset time was 22.9±38.7 days (range: 1 day to 3 years). The most common organism isolated from infectious keratitis after keratorefractive surgery were Staphylococcus aureus , followed by Mycobacterium and coagulase-negative Staphylococcus . Most of the infections after refractive procedures were sensitive to medical treatment alone, and the ultimate best-corrected visual acuity after medical treatment was as follows: 20/20 or better in 82 cases (37.0%), 20/40 or better in 170 cases (76.5%), and worse than 20/40 in 52 cases (23.5%). Surgical interventions including flap lift, flap amputation, ring removal, and keratoplasty were performed in 120 eyes (44.5%). CONCLUSIONS: Most infections after keratorefractive surgery occur within a week, whereas more than half of the cases after laser-assisted in situ keratomileusis happen after about a month. Gram-positive cocci and mycobacterium are the most common isolates. Infections after LASIK, intracorneal ring (ICR) implantation, and small incision lenticule extraction, which primarily occur between the cornea layers, require irrigation of the tunnels or pocket with antibiotics.

RESUMO

PURPOSE: To describe a case of a patient treated for neurotrophic keratopathy (NK) with direct corneal neurotization (CN), where a modification to the CN technique allowed for semiscleral contact lens use postoperatively. OBSERVATION: Our patient had successful CN with improved corneal sensation. During the procedure, a 1.0 mm gutter was created between the limbus and nerve graft to allow for semiscleral contact lens fitting. CONCLUSIONS: With the use of preoperative planning and a limbal gutter during CN, a semiscleral contact lens can serve as a well-tolerated postoperative management option to improve visual acuity and protect the corneal surface in patients with NK.

RESUMO

PURPOSE: To establish the importance of using a sufficiently large corneal graft in primary penetrating keratoplasty in order to prevent recurrence of fungal keratitis. OBERSERVATIONS: A 58-year-old female patient underwent emergency penetrating keratoplasty (diameter 7.0 mm, double running suture) for therapy-resistant fungal keratitis (Fusarium solani) at an external eye clinic. Despite intensive antifungal therapy, new fungal infiltrates appeared in the host cornea after a few days. The patient was referred to our department for further treatment. On first presentation, circular infiltrates were seen around the corneal graft with anterior chamber involvement and therapy-resistant hypopyon. We performed an emergency penetrating repeat keratoplasty (diameter of 13.0 mm, 32 interrupted sutures) combined with anterior chamber lavage and intracameral and intrastromal drug injection. CONCLUSION AND IMPORTANCE: Fungal keratitis sometimes has a frustrating clinical course. Therefore, early diagnosis with effective therapy initiation is of the utmost importance. In cases of penetrating keratoplasty, optimal planning and timing (before anterior chamber involvement) should be provided. Sufficient safety distance must be ensured in the choice of graft diameter, fixation with multiple interrupted sutures, and anterior chamber lavage, as well as intracameral and intrastromal drug administration. Incomplete excision carries a risk of recurrence and endophthalmitis in the course. Close postoperative control is necessary to detect early recurrences.

RESUMO

PURPOSE: Management of NK can be difficult, involving a range of treatments with variable efficacy. We conducted a systematic review and meta-analysis to evaluate the efficacy of medical and surgical treatments for neurotrophic keratitis (NK). METHOD: PubMed, Cochrane Library, Embase, ClinicalTrial.gov, and ScienceDirect were searched for studies assessing efficacy of NK treatments. We computed random-effect meta-analyses on corneal healing, time to complete healing, and visual acuity changes between baselines and after treatment, stratified on treatment classes. We followed the PRISMA guidelines (registration number CRD42021225721). RESULTS: We included 20 studies: 571 patients and 5 treatment classes (2 surgical and 3 non-surgical). The percentage of patients with complete corneal healing did not differ between specific treatments (nerve growth factor eyedrops (NGF), 75%, 95CI 46 to 104%; autologous serum (AS), 92%, 86 to 98%; neurotization, 99%, 95 to 103%; amniotic membrane transplantation (AMT), 86%, 78 to 94%). All specific treatments had better percentage of complete healing (p < 0.001) than non-specific treatment groups, i.e., mainly lubricants (23%, 14 to 32). Time to complete healing was 24.2 days (5.4 to 43.1) with NGF, 27.6 days (15.2 to 40.0) with AS, 117 days (28.8 to 205.2) with neurotization, and 16.4 days (11.1 to 21.7) with AMT. Only NGF and AMT improved visual acuity. Efficacy outcomes were not affected by sociodemographic (age, sex) nor severity of disease (Mackie stages). CONCLUSION: We confirmed the efficacy of specific treatments in NK. Further comparative trials are needed to investigate the medical and economic benefits of innovative therapies.

RESUMO

BACKGROUND: To present a case with a history of laser in situ keratomileusis (LASIK) developing diffuse lamellar keratitis (DLK) after diamond burr superficial keratectomy (DBSK) for recurrent corneal erosion (RCE). CASE PRESENTATION: A 25-year-old man presented with multiple episodes of RCE one year after femtosecond-assisted LASIK for myopia correction. Because conservative treatments failed to halt the repetitive attack of RCE, he underwent epithelial debridement and DBSK. However, severe foreign body sensation and blurred vision developed on postoperative day one. The next day, slit lamp biomicroscopy revealed DLK manifested as diffuse granular infiltrates at the flap interface. After topical corticosteroid treatment, the inflammation resolved gradually, and his vision recovered to 20/20. CONCLUSIONS: Diffuse lamellar keratitis is a rare post-LASIK complication that can be triggered by DBSK, which causes impairment of the corneal epithelial integrity and subsequent inflammation at the flap interface. For post-LASIK patients with RCE, alternative treatments, such as anterior stromal puncture, may be considered to avoid extensive disruption of corneal epithelium and DLK development depending on the size and the location of the lesions.

RESUMO

Microbial, infectious keratitis is a relevant indication for penetrating keratoplasty. The requirement for transplantation results in histopathological examination of the entire thickness of the cornea. Although the clinical diagnosis is not always possible to confirm, pathology can support diagnostic evidence of clinical presentation and pathogenesis. This is achieved with multiple methods from cytology, histochemistry, immunohistology, molecular pathology and in rare cases electron microscopy. These allow tissue-based detection of previous and parallel diseases and the responsible pathogens. The failure of satisfactory clinicopathological correlation raises the question whether a suspected pathogen was not ultimately responsible for destroyed corneal tissue. The pathogenesis of keratitis requiring transplantation is not yet completely understood, also on the experimental level. The development of such a keratitis can lead to a clinical symptomatology which can be described as "threatening organ dysfunction", a term used in sepsis research. Considering recent literature, possible correlations between sepsis and microbial keratitis and their relation to histopathology are discussed.

RESUMO

PURPOSE: To report the indications and outcomes of penetrating keratoplasties with a graft diameter > 8.5 mm in severe corneal diseases at the Department of Ophthalmology at Saarland University Medical Centre. STUDY DESIGN: Retrospective (6 years), descriptive, and observational. METHODS: Thirty-five large-diameter penetrating keratoplasties (LDPKPs) in 27 patients (mean age, 62 ± 22 years) were performed from March 2010 to December 2016. The indication for surgery, number of previous corneal transplantations, best-corrected visual acuity (BCVA) before surgery, intraocular pressure, graft status, and BCVA at last follow-up were recorded. RESULTS: Infectious keratitis represented 83% of the indications (of those, 45% fungal). The mean corneal graft diameter was 10.8 ± 1.7 (min 8.75, max 15.0) mm. Twenty-three eyes (65% absolute) had at least one previous penetrating keratoplasty (mean graft size, 9.2 ± 1.6 mm). The mean pre-surgery BCVA was 1.96 ± 0.23 logMAR. With a mean follow-up period of 20.2 ± 13.4 months, the mean BCVA was 1.57 ± 0.57 logMAR at last follow-up. Overall, 12 grafts (35%) remained clear until the last follow-up, and in 23 grafts (65%), the primary disease recurred, or corneal decompensation developed. Up to the last follow-up, 6 eyes (17%) had to be enucleated. CONCLUSIONS: In complex cases of infectious keratitis requiring a LDPKP to remove the complete pathology and preserve eye integrity, the visual outcomes are generally expected to be poor, not only because of the well-known risks of LDPKP but also because of the consequences of the infectious disease itself. This knowledge is important for adequate counselling of the patient preoperatively.

RESUMO

PURPOSE: To highlight the typical histological and ultrastructural features of severe infectious crystalline keratopathy (ICK) in a corneal graft, which required excimer laser-assisted repeat penetrating keratoplasty (PKP) and to present the challenging treatment conditions associated with ICK. METHODS: An 85-year-old female patient underwent PKP for secondary graft failure after Descemet membrane endothelial keratoplasty (DMEK) for Fuchs' endothelial corneal dystrophy in the left eye. One year later, white branched opacities were observed in the superficial corneal stroma of the graft without surrounding inflammation in the left eye. The patient underwent excimer laser-assisted repeat PKP (8.0/8.1 mm) in the left eye after prolonged refractory topical anti-infectious treatment for 1 month. The corneal explant was further examined by light and transmission electron microscopy (TEM). RESULTS: The light microscopic examination of the corneal explant demonstrated aggregates of coccoid bacteria in the superficial and mid-stromal region that were positive for periodic acid-Schiff (PAS) and Gram stain. The bacterial aggregates extended into the interlamellar spaces, showed a spindle-shaped appearance, and were not surrounded by an inflammatory cellular reaction. TEM demonstrated lamellae separation within the anterior corneal stroma with spindle-shaped aggregates of bacteria, which were embedded in an extracellular amorphous matrix with incipient calcification, being consistent with a biofilm. No inflammatory cellular reaction was evident by TEM. At discharge from hospital, the corrected visual acuity was 20/80 in the left eye. CONCLUSION: ICK is often challenging due to the difficult diagnosis and treatment conditions. The refractory courses are mainly attributed to a biofilm formation, which inhibits effective topical anti-infectious treatment. In such cases, (repeat) PKP may be necessary to completely remove the pathology, prevent recurrences, and improve vision.

RESUMO

Ocular symptomatology in lesions of the facial nerve is associated with disturbed innervation of the circular muscle of the eye that leads to disruption of the protective function of the eyelids and the development of exposure symptoms, and is accompanied by a breach in corneal tear film integrity. The main clinical manifestation of the trigeminal nerve damage is the loss of sensory innervation of the cornea and disruption of the supply of neurotransmitters to its cells, manifesting as corneal hypo- or anesthesia. This triggers a cascade of pathological processes that lead to the development of neurotrophic keratopathy. In combined pathology of the facial and trigeminal nerves, a number of interrelated and mutually aggravating problems arise that require correction of lagophthalmos and functional restoration of the trigeminal nerve, since there is an interaction between the corneal epithelium and trigeminal neurons through trophic neuromodulators, which normally contribute to the proliferation of epithelial cells, their differentiation, migration and adhesion, and are essential for vital functions, metabolism and healing of surface lesions of the eye. Classical methods of treating neurotrophic keratopathy aim to protect the ocular surface, and are palliative or auxiliary, do not provide radical relief of the symptoms of neurotrophic keratopathy. Modern surgical technique of neurotization of the cornea allows restoring the structural growth of the nerve, which provides nerve trophism and corneal sensitivity, and is the only pathogenetically substantiated method of effective treatment of neurotrophic keratopathy. At the same time, direct neurotization has undeniable advantages over methods involving intercalary donor nerves, since neuropeptides from nerve fibers are immediately released into the recipient tissue and start reparative processes. Taking into account the accumulated positive experience of neurotization surgeries, scientific and clinical research should be continued in order to improve the most effective methods of corneal neurotization and promote their wider implementation into clinical practice.

RESUMO

PURPOSE: In this paper, we describe two cases of fungal interface infectious keratitis (IIK) developed after endothelial keratoplasty (EK) who underwent delayed therapeutic penetrating keratoplasty (TPK) with a poor visual outcome. Furthermore, we conducted a review of the literature and analyzed the visual outcomes of TPK in relation to the time from IIK diagnosis. METHODS: We searched the literature for fungal IIK cases occurred after EK and treated by TPK. We identified 17 cases of fungal IIK, mostly caused by Candida spp. (88%). RESULTS: Infection was diagnosed at a median time of 21 (range 1-90 days) days after EK. The median lag time between infection diagnosis and TPK was 30 (range 7-393) days. The median distance corrected visual acuity (DCVA) measured 4-12 months after surgery was 20/40 (range 20/200-20/20). When TPK was performed within one month from diagnosis, the final median DCVA was 20/30 (range 20/100-20/20), with 83% of patients achieving ≥ 20/40 vision. When TPK was carried out later, the final median DCVA was 20/50 (range 20/200-20/22) with 44% of patients achieving ≥ 20/40 vision. One patient in the early surgery and four patients in the late surgery group showed postoperative DCVA ≤ 20/100 despite clear grafts. CONCLUSION: TPK with removal of the sequestered infection is advocated as a safe and effective measure to treat a post-EK infection. Early surgery allows a reduced exposure time to infection and therefore may result in better visual outcomes and lower risk of complications caused by prolonged inflammation.

RESUMO

Infectious keratitis is one of the most common causes of blindness worldwide. Despite the existence of a wide arsenal of quite effective antimicrobial drugs, some forms of bacterial and viral keratitis are resistant. Advanced acanthamoeba and mycotic lesions of the cornea, as well as mixed forms of infection usually do not respond well to conservative treatment. In the absence of positive dynamics from the applied etiotropic therapy with observed further progression of the microbial process, there is a risk of corneal perforation and spread of infection to the sclera or deep ocular structures with a high probability of irreversible functional disorders or anatomical death of the eye. In such cases, a timely transition to surgical treatment is necessary in order to maintain structural integrity of the eyeball. For this purpose, corneal crosslinking, microdiathermocoagulation, tissue adhesive, autoconjunctival plasty, amniotic membrane, corneoscleral flap coating, various combinations of these methods, as well as therapeutic keratoplasty are used most often in clinical practice. The choice depends on the etiology, size and depth of the lesion, its localization, prognosis of visual outcomes, somatic status of the patient. Therapeutic keratoplasty is the most radical and effective method of surgical intervention that allows eradication of the infectious focus and best possible restoration of the structural integrity of the eyeball. However, in some cases due to inaccessibility of donor material or high risks of the surgery and non-transparent graft engraftment, it is advised to use alternative surgical approaches, and keratoplasty, if necessary, should be carried out for optical purposes at a further, "quiet" period.

RESUMO

PURPOSE: The purpose of this study was to examine the outcomes of conjunctival flaps performed at our institution. METHODS: The medical records of all patients who underwent a total or partial conjunctival flap surgery over the course of a 6-year period from 2010 to 2015 were reviewed to identify the ocular diagnoses and perform a retrospective review of the preoperative and postoperative course. RESULTS: Thirty-five patients received a conjunctival flap during the 6-year period, 20 partial flaps and 15 total flaps. Infectious keratitis or corneal ulceration accounted for 25 (71.4%) of the cases. The remaining flaps were performed for corneal perforation, graft rejection, bullous keratopathy, and secondary corneal edema. Seven patients had recession of their flap postoperatively, and 14 went on to have further surgical intervention. Conjunctival flap surgery successfully stabilized the patient's ocular surface in 97.1% of the cases. CONCLUSION: Conjunctival flap surgery is an important and useful surgical option in the treatment of ocular surface disease, especially recalcitrant infectious keratitis and corneal ulcers.

RESUMO

A 70-year-old white woman presented to her ophthalmologist with bacterial conjunctivitis resistant to treatment. The relationship between the patient's globe and superior orbital rim prompted high clinical suspicion of an occult foreign body as the cause. The following article describes the office visits preceding the discovery of two adhered soft contact lenses lodged in the superior fornix of the right eye that had been hidden for 15 years. We discuss the role her unique orbital anatomy played in successfully concealing these foreign bodies for over a decade. In addition, we present an algorithm to practice when an occult foreign body is suspected, which includes effective clinical techniques.

RESUMO

BACKGROUND: Primary localised orbital amyloidosis (PLOA) is a very rare disease. In contrast to the isolated manifestation, systemic involvement can be associated with potentially life-threatening consequences. However, the isolated involvement of the orbit can also lead to serious complications. MATERIAL AND METHODS: Two cases of PLOA are described and the necessary ophthalmic, internistic and immunohistochemical diagnostic testing are explained. RESULTS: The first case describes a 71-year-old woman with PLOA. In the clinic, a yellow-orange bumpy prominence in the nasal lower quadrant without further ophthalmological abnormalities was found. Extensive diagnostic testing found no systemic manifestation. The patient herself was free of complaints. In the follow-up over 4 years, patient showed slow progression without ocular complications. The second case is a 72-year-old male patient with similar clinical signs but localisation in the temporal superior quadrant. During the clinical course, multiple ophthalmological complications developed (ptosis, protrusio bulbi, diplopia, secondary glaucoma, perforated corneal ulcer in neurotrophic keratopathy). Perforating keratoplasty had to be performed. Fractioned radiotherapy led to stabilisation of the disease. The follow-up period was 4 years. CONCLUSION: PLOA can lead to visual and organ threatening complications. Accurate diagnosis is required for further diagnostic and therapeutic procedures and to counteract potential local and systemic complications. Interindividual differences in the course have to be considered.

RESUMO

PURPOSE: To present the long-term results of therapeutic keratoplasty for microbial keratitis in moderate to advanced phases. METHODS: The medical records of 44 patients who underwent therapeutic keratoplasty for microbial keratitis at the ophthalmology clinic of a training and research hospital between June 2012 and March 2018 were reviewed in this retrospective study. RESULTS: Of the 65 patients that underwent TPKP, 44 eyes of 44 patients met the inclusion criteria and enrolled in this study. The most commonly found predisposing factor for keratitis was a history of trauma (n = 17, 38.6%), and most of them had occurred with a vegetative matter (n = 14, 31.8%). The most common clinically suspected cause was fungal (n = 17, 38.6%) followed by bacterial (n = 12, 27.3%). In 26 (59.1%) cases, the causative microorganism could not be proved with a microbial culture. The most common causative microorganism was Staphylococcus spp. (n = 4, 9.1%), followed by Fusarium solanii (n = 3, 6.8%). The mean follow-up time was 42 (range 12-54) months. At the last follow-up visit, anatomical success was achieved in 40 (90.9%) cases and the BCVA of more than half of the patients was over 1.0 (logMAR, n = 24, 54.5%). Most commonly seen complication was found to be secondary glaucoma (n = 19, 43.2%), followed by cataracts (n = 9, 34.6%) and graft rejection (n = 12, 27.3%). CONCLUSIONS: TPKP offers a definitive solution in the management of microbial keratitis with high rates of anatomical and functional success. However, secondary glaucoma is the most common complication after TPKP, which was seen in almost half of the patients.

RESUMO

BACKGROUND: The utility of formalin-fixed paraffin-embedded (FFPE) corneal tissue specimens for retrospective diagnosis of microsporidial keratitis was evaluated by transmission electron microscopy (TEM) analysis and the possible second case of microsporidial keratitis after Descemet stripping automated endothelial keratoplasty (DSAEK) was described. CASE PRESENTATION: A 68-year-old man presented with multiple crystalline opacities in the corneal stroma that progressed extremely slowly after DSAEK. Fungiflora Y staining of corneal scrapings from the affected regions revealed an oval microorganism. Topical voriconazole administration was ineffective and penetrating keratoplasty was performed. Histological and molecular analyses were carried out on the excised cornea. Ziehl-Neelsen staining revealed an acid-fast, oval organism that was visible by ultraviolet illumination after Fungiflora Y and Uvitex 2B staining, whereas periodic acid-Schiff and Grocott's staining did not yield any significant findings. Microsporidium was detected by TEM of FFPE tissue. Nosema or Vittaforma sp. was suspected as the causative microorganism by PCR of FFPE tissue and by the fact that those species are known to cause eye infection. The corneal graft has maintained transparency at 1 year and half postoperatively. CONCLUSIONS: This is the first known case of microsporidial keratitis diagnosed retrospectively by molecular and ultrastructural study of FFPE tissue, and the possible second case of microsporidial keratitis after DSAEK. Microsporidial keratitis should be considered when corneal opacity refractory to conventionally known therapy would occur after DSAEK. Our findings suggest that more microsporidial keratitis cases than have been reported to date can be identified by TEM or PCR examination of FFPE corneal specimens.

RESUMO

Corneal neurotization represents an effective surgical strategy to restore corneal sensibility in patients affected by neurotrophic keratopathy.Corneal sensibility is essential in preserving structure and function of the eye. Loss of corneal sensibility can lead to a degenerative condition of the cornea known as neurotrophic keratopathy.Moreover, patients suffering from facial palsy show failure of full eyelid closure resulting in chronic corneal exposure and subsequent progressive damage.Reports have shown that the use of the contralateral ophthalmic division of the trigeminal nerve can be effective in restoring corneal sensibility. In the present study the authors expose a new technique by means of which direct neurotization of the anesthetic cornea was achieved using the homolateral second division of the trigeminal nerve. Effectiveness of the technique was evaluated using in vivo confocal microscopy.To the best of authors' knowledge, this is the first report of this technique in literature.

RESUMO

A 14-year-old girl with a history of keratitis-ichthyosis-deafness (KID) syndrome, a rare autosomal dominant condition, was referred to the Department of Plastic Surgery at Brussels University Hospital in June 2016 for progressively worsening inguinoperineal ulceration exacerbated by overapplication of combination drug treclinax (tretinoin and erythromycin). On assessment, a large area of purulent papillomatous hyperkeratosis with follicular plugging, likely superimposed bacterial colonization, and deep ulceration were noted requiring thorough debridement.A first procedure was performed in June 2016 with hydrosurgical debridement (Versajet IITM; Smith & Nephew, Forth Worth, Texas). During the procedure, significant blood loss was noted, and topical adrenaline, blood transfusion, and a short ICU stay were required for monitoring during which the patient remained hemodynamically stable. The wound was primarily dressed with an antimicrobial barrier silver dressing; meropenem, ceftazidime, and fluconazole were started to treat for Gram-negative, Gram-positive, and anaerobic bacilli, as well as Pseudomonas aeruginosa and fungal infections in situ. A further three debridements were required 6, 12, and 26 days after the initial procedure. The patient was discharged 36 days after admission without any antibiotics and with an outpatient wound care plan.Not only was this case rare, but it also reflected the importance of a careful approach when tackling KID syndrome's cutaneous manifestations. Multiple debridements, thorough wound care, and appropriate antibiotic therapy may be required to achieve local healing and a satisfactory result. Hydrosurgical debridement offered a precise and well-controlled method for treating a large ulcerating hyperkeratotic urogenital lesion in this pediatric patient.
