RESUMO

Összefoglaló. Bevezetés: Az elso szaruhártya-bank 1944-es alapítása óta jelentos változásokon ment át. A szaruhártya túlélését számos tényezo befolyásolja, így a tárolási mód, melynek a szövet lejárati ideje szerint rövid, közép és hosszú távú módszereit fejlesztették ki. Célkituzés: Retrospektív vizsgálatunk célja a 2008. január 1. és 2017. december 31. között perforáló és lamelláris keratoplasztika során felhasznált cadaverbol és multiorgan donorból származó szaruhártyák túlélésének vizsgálata volt a Semmelweis Egyetem Szemészeti Klinikáján. Módszer: Feljegyeztük a recipiens nemét, életkorát, a mutétet indikáló klinikai diagnózist, a mutét idopontját, a szövettani vizsgálat eredményét, valamint, hogy a beültetett szaruhártya cadaverbol vagy multiorgan donorból származott. Meghatároztuk, hogy a recipiens életkora korrelált-e a rekeratoplasztikáig eltelt idovel. Eredmények: 1451 szaruhártya-átültetés történt 1088 beteg (44,6% férfi) 1159 szemén (életkor 62,8 ± 18,5 év), melyek között 938 (64,6%) cadaver és 262 (18,0%) multiorgan donor került felhasználásra, 251 esetben (17,2%) nem állt rendelkezésre adat. A leggyakoribb primer diagnózis a szaruhártya-dekompenzáció volt (325 eset, 28%). A primer keratoplasztikák során felhasznált szaruhártyák 740 esetben (63,8%) cadaverbol, 212 esetben (18,2%) multiorgan donorból származtak, 207 esetben (17,8%) nem állt rendelkezésre adat. Elso rekeratoplasztika a primer keratoplasztikák közül 217 esetben (18,7%) történt. A leggyakoribb szövettani diagnózis az endothelsejt-degeneráció volt (130 esetben, 60,4%). 146 esetben (67,2%) korábban cadaver, 31 esetben (14,2%) multiorgan donor esetén került sor ismételt mutétre, 40 esetben (18,4%) nem állt rendelkezésre adat. Következtetés: Klinikánkon elsosorban cadaverbol származó donorok biztosítják a szaruhártya átültetésekhez szükséges szövetet. Cadaverbol vagy multiorgan donorból származó szaruhártyák esetén nem kerül gyakrabban sor rekeratoplasztikára. A szaruhártya-banki tevékenység további fejlesztésével növelheto a donorok túlélése hazánkban. Orv Hetil. 2021; 162(13): 488-496. INTRODUCTION: Corneal banking methods have been changing since the foundation of the first corneal bank in 1944. Corneal graft survival may be affected by several factors, among others the storage method, which may be short-, middle- and long-term storage. OBJECTIVE: To investigate corneal graft survival at the Department of Ophthalmology, Semmelweis University between 1 January 2008 and 31 December 2017, using cadaver and multiorgan donors for penetrating and lamellar keratoplasty, retrospectively. METHOD: Recipient sex, age, clinical diagnosis, date of surgery, histological examination results and origin of donors (cadaver or multiorgan donor) were recorded. Correlation between recipient age and time to repeat keratoplasty was also analyzed. RESULTS: There were 1451 keratoplasties in 1159 eyes (age 62.8 ± 18.5 years) of 1088 patients (44.6% male) using 938 (64.6%) cadaver and 262 (18.0%) multiorgan donors, data was not available in 251 (17.2%) cases. There was repeat keratoplasty in 217 patients (18.7% of first keratoplasties). The most common histological diagnosis was endothelial decompensation (130 cases, 60.4%) in these cases. In patients with a first repeat keratoplasty, in 146 cases (67.2%) the first donor originated from cadavers, in 31 cases (14.2%) from multiorgan donors and in 40 cases (18.4%) data were not available. CONCLUSION: Corneal donors mainly originate from cadavers at our Department. The necessity of repeat keratoplasties does not differ using cadaver or multiorgan donors. With further development of corneal banking, donor survival may be increased in Hungary. Orv Hetil. 2021; 162(13): 488-496.

RESUMO

The great potential of contact lenses for improving vision in all forms of corneal irregularities, e. g. keratoconus, after keratoplasty, after keratitis, is in danger of being forgotten. Especially by the younger generation of ophthalmologists and opticians there is a risk that the skill of fitting contact lenses professionally will be lost. There are many situations in which the practicing ophthalmologist should recognize that the contact lens can be a useful option for the visual rehabilitation of his patient. In this article, we provide a summary of "The basics of practical contact lens fitting". The first part is about materials, fields of application and differences in optics compared to glasses.

RESUMO

Purpose: The aim of this study was to analyze the impact of COVID-19 lockdown on keratoplasty and Eye Banking in India. Methods: An e-mail survey was conducted among cornea surgeons and eye bankers of India. Participants were asked to report their practice patterns for the management of corneal perforation during lockdown, different preservative media used during and before lockdown, and waiting time and waiting time before COVID-19 lockdown. Results: Eight of 20 eye banks did not collect corneal tissue during April-June 2020; in contrast, 9 eye banks used to collect around 100 corneas per month during pre-COVID-19 time. Two-third of the surgeons (66.1%, n = 41/62) did not perform any corneal tissue transplant between April and June 2020. Cyanoacrylate tissue adhesive application was the most commonly, performed procedure (79%, n = 49/62) for tectonic purpose during this period. Glycerol was the most preferred alternative preservation method considered by both the groups. More than half of the surgeons (64.5%, n = 40/62) had an average waiting time of <1 week for scheduling patients for keratoplasty in pre-COVID-19 period. Conclusion: There is was a significant drop in both corneal tissue retrieval and utilization during during COVID-19 lockdown. There was a felt need for an alternate long term storage media.

RESUMO

Persistent corneal graft erosion or persistent epithelial corneal defect is a frequent complication of penetrating keratoplasty. Its development can be contributed by the dry eye syndrome, rare blinking, lagophthalmos, symblepharon, viral infection, autoimmune aggression, and the use of epithelial-toxic eye drops. The article presents three clinical observations of patients who developed persistent corneal graft erosion after penetrating keratoplasty. Due to the ineffectiveness of local conservative therapy for more than 3 weeks, anterior stromal corneal micropuncture was performed. After the procedure, there was a gradual epithelial proliferation, complete healing of the corneal surface was observed 10-16 days after the manipulation, the follow-up period was at least 1 year. The mechanism of action of stromal micropuncture is associated with the creation of a porous surface with better adhesion properties, as well as with the activation of the production of extracellular matrix glycoproteins such as fibronectin, type IV collagen and laminin, which are necessary for stable adhesion of the epithelium. The use of stromal micropuncture of the donor flap in the treatment of post-keratoplasty persistent corneal epithelial defect was proposed for the first time.

RESUMO

A 34year-old man presented with diminution of vision, pain and whitish opacity in both eyes (right eye followed by left eye) since 1 week. He is a known case of chronic alcoholic abuse. He had multiple episodes of haemoptysis in the past. On general physical examination, he was severely malnourished with multiple oral ulcers. Visual acuity at presentation was light perception in both eyes with projection of rays accurate in all quadrants. Slit-lamp biomicroscopy revealed bilateral total corneal melt with diffuse conjunctival congestion. Corneal scrapings and blood investigations were done and he was started on empirical topical and systemic therapy followed by surgical intervention, with large corneal grafts in both the eyes (right eye followed by left eye) with 1 day interval. The visual gain in both the eyes were 20/400 at first postoperative day. The right eye developed severe fibrinous reaction on the second postoperative day which resolved with topical antibiotics, topical steroids and systemic steroids. The patient was followed up via telemedicine (due to COVID-19 outbreak) and he is able to carry out his daily routine work independently.

RESUMO

To report the clinical course and management of interface keratitis due to Enterococcus faecalis after Descemet membrane endothelial keratoplasty (DMEK). A 64-year-old man underwent DMEK, with unevenful immediate postoperative course, with a visual recovery of 20/30 at 2 weeks. At 3 months of clinical visit, interface keratitis was noted. DMEK graft removal with stromal bed scrapings was performed. A diagnosis of E. faecalis interface keratitis was made. The patient responded favourably to antibiotic susceptibility-guided intensive treatment with vancomycin 5% with complete resolution of infection. After 2 months of graft removal, Descemet stripping endothelial keratoplasty (DSEK) was performed. The corneal clarity was restored and the best corrected visual acuity was 20/40 at last follow-up of 1 year. E. faecalis should be kept as a differential in delayed onset interface keratitis after DMEK. After microbiological cure with antibiotic therapy, visual rehabilitation with DSEK restores corneal clarity and results in favourable visual outcome.

RESUMO

In this paper, we report the psychological and emotional experience of a patient who regained vision after over a decade of vision loss. The negative psychological implications of blindness are well recognised and there is a robust link between visual impairment and low mood and depressive symptoms. Although uncommon, low mood and depressive symptoms have been reported in patients whose sight has been restored, and lack of research gives rise to the possibility their prevalence may be grossly under-recognised in such patient groups. The effects can be so severe that patients may revert to living in darkness in mimicry of their previous lifestyle, effectively obviating the sight-restoring surgery. Healthcare professionals have a responsibility to address this traditionally neglected need by facilitating social, psychological and medical interventions that may ease the return to vision.

RESUMO

The use of sulfur mustard (SM) in global terrorism is still a relevant threat to both civilian population and military personnel. Casualties exposed to SM may present mild, moderate or severe acute ocular lesions followed by a complete ocular resolution, chronic lesions or re-emerged ocular pathologies after a latent period. Current treatment for SM-induced ocular injury is based mainly on the clinical manifestation at the different stages of the injury and includes pharmaceutical and surgical interventions. These therapeutic measures are beneficial but not sufficient, and the ocular injury remains a continuous challenge for medical professionals. This review focuses on treatment experience carried out in humans and studied in animal models, for both SM-induced ocular acute injury and late pathology. In general, therapeutic measures are based on clinical features of the ocular injury or on the involvement of specific factors during the ocular injury that point out towards potential treatments. Anti-inflammatory treatments and limbal stem cell transplantation techniques were developed based on the clinical manifestation of the ocular injury. Optional therapies for impaired corneal innervation and endothelium are suggested for future research. Additionally, studies on potential treatments with anti-matrix metalloproteinase (MMP), anti-vascular endothelial growth factor (VEGF) and anti-IL-6 agents are discussed. Consequently, future studies may reveal the potential of additional pharmacological and biological treatments or advanced cellular and molecular biology methods to serve as novel therapeutic measures and techniques for this complicated ocular injury.

RESUMO

Limbal Stem Cell Deficiency (LSCD) is an ocular surface disease caused by the decrease of the quantity and dysfunction of limbal stem cell, which is characterized by conjunctivalization and other signs of epithelial dysfunction. For sever LSCD, surgery is the main treatment way. Recently, plenty of researches published the outcomes of different operation methods. This article summarized five major operations, including conjunctival limbal autograft (CLAU), simple limbal epithelial transplantation (SLET), limbal allograft, cultivated limbal stem cell transplantation (CLET) and cultivated oral mucosal epithelial transplantation (COMET). (Chin J Ophthalmol, 2020, 56:956-960).

RESUMO

PURPOSE: To clinically evaluate the results of one-piece mushroom-shaped keratoplasty. MATERIAL AND METHODS: A total of 10 patients (10 eyes) were enrolled, all having corneal perforations and deep stromal opacities with involvement of Descemet's membrane. For transplantation, hypothermic preserved donor corneas with mean endothelial cell density of 2896±327 cells per 1 mm2 were used. Surgical technique. Recipient tissues as well as the graft were cut with the Moria trephine. For that, the 8.5-mm blade was replaced by a 6.5-mm one and vice versa, respectively, with attention paid not to violate the vacuum while making the cuts. RESULTS: Transparent cornea engraftment was achieved in all patients. Best corrected visual acuity averaged 0.55±0.22. Spherical component of refraction varied from -4.25 to +2.75 diopters. Mean corneal astigmatism was 3.35±1.73 diopters. At 6 months after surgery, the mean endothelial cell density was 2355±336 cells/mm2, at 1 year - 2141±304 cells/mm2. CONCLUSION: One-piece mushroom keratoplasty is an effective surgical treatment of corneal perforations and deep stromal opacities with involvement of Descemet's membrane that ensures a high rate of transparent corneal engraftment. The use of the Moria vacuum trephine in combination with blades of different diameters and secure fixation of the vacuum part of the trephine eliminate the risk of the 'mushroom stem' decentration relative to its 'head'.

RESUMO

PURPOSE: To evaluate the effectiveness and safety of adjuvant anti-VEGF therapy in the surgical treatment of pterygium, and to determine the indications for its use. MATERIAL AND METHODS: The study included 67 patients (69 eyes) with grade II-IV pterygium. Patients age was 58.8±12.6 years on average. Best corrected visual acuity (BCVA) varied between 0.01 and 1.0 (0.77±0.24). The patients were divided into 3 groups. The first group included 19 patients (19 eyes) with grade II-III pterygium who underwent «bare sclera¼ surgery and used aflibercept as adjuvant therapy. The second group included 21 patients (21 eyes) with grade II-IV pterygium who underwent auto conjunctival grafting surgery with no adjuvant therapy. The third group included 27 patients (29 eyes) with grade II-IV pterygium who had it removed in combination with single-time peripheral lamellar keratoplasty (PLK) and underwent adjuvant aflibercept therapy. RESULTS: Among patients who underwent pterygium excision with adjuvant antiangiogenic therapy there were 5 cases (26%) of relapse during the observation period (23.38±8.96 months), among patients after pterygium excision with auto conjunctival plastic surgery - also 5 cases (24%) of relapse, and among patients who underwent LKP combined with anti-VEGF therapy there was only 1 case (3%) of relapse. Astigmatism has decreased by 0.24±0.5 (p=0.052) in the first group, by 1.21±1.0 (p<0.05) in the second group, and by 1.64±1.54 (p<0.05) in the third group compared with pre-surgical values, thus increasing average BCVA in all 3 patient groups by 0.1±0.13, 0.07±0.11 and 0.15±0.15, respectively. CONCLUSION: The use of anti-VEGF agents as adjuvant therapy in the surgical treatment of pterygium is a safe method of reducing postoperative inflammation, fibrovascular proliferation and, subsequently, the amount of relapses.

RESUMO

Bandage therapeutic-optical keratoplasty (BTOK) is one of the modern methods of surgical treatment of keratoconus (KC) that allows to improve visual functions by changing keratotopographic and pachymetric parameters of the cornea in the zone of ectasia. Long-term results show that changes also affect the central part of the cornea, which tends to flatten. PURPOSE: To compare the light confocal microscopy appearance of the cornea before and after BTOK surgery. MATERIAL AND METHODS: We examined 15 patients (15 eyes) with progressive keratoconus (7 eyes with Amsler stage I KC and 8 eyes with Amsler stage III KC), who subsequently underwent BTOCK surgery. Using the Confoscan-4 confocal light microscope (Nidek, Japan), we studied the structure of central and paracentral cornea. The exact zone of interest was determined individually depending on the location of the graft. RESULTS: In all cases, morphological changes in the cornea characteristic of the stage II and III KC were detected. Twelve months after the operation, there was an increase in the transparency of intercellular substance of the stroma with a clearer visualization of keratocyte nuclei in the optical zone as well as at the site of the graft. In the area of interface, tissue compaction in the form of diffuse fibrosis with local scar formation could be seen. Neither significant changes in the cell structure, nor a decrease in cell density were found in the central part of ectasia and the areas of clear visualization of the endothelium under the graft. Additional postoperative assessment of the level of corneal light scattering indicated a tendency towards restoration of stromal transparency and optical uniformity. CONCLUSION: As a result of interlayer graft implantation in the zone of corneal ectasia, a tendency to structural improvement in its central and paracentral parts was revealed. Local fibrosis in the interface area can indirectly indicate biomechanical «strengthening¼ of this zone.

RESUMO

As it is known, the main problem of surgical treatment of pterygium is associated with high risk of recurrence. Quite a number of surgical techniques now exist, all aimed at pterygium removal and only differing in the method of conjunctival closure following the excision. Due to relatively low recurrence rates, conjunctival or conjunctival-limbal autografts are currently the 'gold standard' of pterygium surgery. The frequency of recurrence is also insignificant in peripheral anterior lamellar keratoplasty, which is rarely performed due to its complexity and the need for donor cornea. However, it is considered to be the method of choice in cases of repeated recurrence as well as in patients with high pterygium activity. This article describes a clinical case of a massive recurrent pterygium (grade IV, activity level 3). The patient has had three previous surgeries (including conjunctival autotransplantation) that yielded no success. By performing large-diameter peripheral anterior lamellar keratoplasty in combination with adjuvant therapy (intraoperative mitomycin C and subconjunctival postoperative aflibercept injections), structural integrity of the cornea was finally restored without further recurrences and visual acuity was increased.

RESUMO

Purpose: The purpose of this study was to discuss the guidelines and modification of practices with respect to corneal transplantation and eye banking during the COVID-19 pandemic lockdown period and beyond, at a network of tertiary care centers in India. Methods: Descriptive study of the challenges faced in eye banking during the lockdown, and practices adopted to overcome the critical aspects in the clinical care of patients who presented with emergency corneal diseases requiring keratoplasty. Results: Complete lockdown orders from the Indian government, as a strategy to control the Coronavirus pandemic, resulted in drastic reduction of all types of elective corneal transplants and eye banking activities from March 24, 2020 to May 31, 2020. The sudden cessation of eye banking resulted in an acute demand and supply imbalance of fresh donor corneas for transplants during this time. Our network of eye banks addressed this issue by adopting glycerol preservation of donor corneas, which were subsequently utilized for tectonic penetrating keratoplasty. The donor cornea retrieval was resumed in a strategized manner 3 weeks prior to the date of exit of the lockdown, with modified guidelines on donor suitability, screening, retrieval, processing, and harvesting from various sources. A triage of keratoplasty priority was formulated to tide over the post lockdown shortage of corneas. We performed 31 therapeutic keratoplasties during the nationwide lockdown among our network of tertiary eye care centers. Conclusion: The study highlights the approach and strategies to manage and tide over an unprecedented crisis situation faced by corneal surgeons in general and, specifically, the eye banking community.
