RESUMEN

BACKGROUND: Retinopathy of prematurity is treated with laser photocoagulation under general anaesthesia with intubation using endotracheal tube (ETT), which carries a risk for postoperative mechanical ventilation (MV). Laryngeal mask airway (LMA) may provide a safe alternative. We assessed the need for postoperative MV in preterm infants who received LMA versus ETT. METHODS: In this single-centre, retrospective cohort study, preterm infants who underwent laser photocoagulation between 2014-2021 were enroled. For airway management, patients received either LMA (n = 224) or ETT (n = 47). The outcome was the rate of postoperative MV. RESULTS: Patients' age were 37 [35;39] weeks of postmenstrual age, median bodyweight of Group LMA was higher than Group ETT's (2110 [1800;2780] g versus 1350 [1230;1610] g, respectively, p < 0.0001). After laser photocoagulation, 8% of Group LMA and 74% of Group ETT left the operating theatre requiring MV. Multiple logistic regression revealed that the use of LMA and every 100 g increase in bodyweight significantly decreased the odds of mechanical ventilation (OR 0.21 [95% CI 0.07-0.60], and 0.73 [95% CI 0.63-0.84], respectively). Propensity score matching confirmed that LMA decreased the odds of postoperative MV (OR 0.30 [95% CI 0.11-0.70]). CONCLUSION: The use of LMA is associated with a reduced need for postoperative MV. IMPACT: Using laryngeal mask airway instead of endotracheal tube for airway management in preterm infants undergoing general anaesthesia for laser photocoagulation for treating retinopathy of prematurity could significantly decrease the postoperative need for mechanical ventilation. According to our current understanding, this has been the largest study investigating the effect of laryngeal mask airway during general anaesthesia in preterm infants. Our study suggests that the use of laryngeal mask airway is a viable alternative to intubation in the vulnerable population of preterm infants in need of laser treatment.

RESUMEN

Cystinosis is a low-prevalence lysosomal storage disease. The pathomechanism involves abnormal functioning of the cystinosine lysosomal cystine transporter (CTNS), causing intraliposomal accumulation of the amino acid cysteine disulfide, which crystallizes and deposits in several parts of the body. The most common ophthalmic complication of cystinosis is the deposition of "gold dust" cystine crystals on the cornea, which already occurs in infancy and leads to severe photosensitivity and dry eyes as it gradually progresses with age. In the specific treatment of cystinosis, preparations containing cysteamine (CYA) are used. The availability of commercialized eyedrops for the targeted treatment is scarce, and only Cystadrops® are commercially available with strong limitations. Thus, magistral CYA-containing compounded eyedrops (CYA-CED) could have a key role in patient care; however, a rationally designed comprehensive study on the commercialized and magistral products is still missing. This work aims to build up a comprehensive study about commercialized and magistral CYA eye drops, involving pharmacokinetic and physicochemical characterization (applying mucoadhesivity, rheology test, investigation of drug release, and parallel artificial membrane permeability assays), as well as ex vivo tests, well supported by statistical analysis.

RESUMEN

RNA modifications play a fundamental role in cellular function. Pseudouridylation, the most abundant RNA modification, is catalyzed by the H/ACA small ribonucleoprotein (snoRNP) complex that shares four core proteins, dyskerin (DKC1), NOP10, NHP2, and GAR1. Mutations in DKC1, NOP10, or NHP2 cause dyskeratosis congenita (DC), a disorder characterized by telomere attrition. Here, we report a phenotype comprising nephrotic syndrome, cataracts, sensorineural deafness, enterocolitis, and early lethality in two pedigrees: males with DKC1 p.Glu206Lys and two children with homozygous NOP10 p.Thr16Met. Females with heterozygous DKC1 p.Glu206Lys developed cataracts and sensorineural deafness, but nephrotic syndrome in only one case of skewed X-inactivation. We found telomere attrition in both pedigrees, but no mucocutaneous abnormalities suggestive of DC. Both mutations fall at the dyskerin-NOP10 binding interface in a region distinct from those implicated in DC, impair the dyskerin-NOP10 interaction, and disrupt the catalytic pseudouridylation site. Accordingly, we found reduced pseudouridine levels in the ribosomal RNA (rRNA) of the patients. Zebrafish dkc1 mutants recapitulate the human phenotype and show reduced 18S pseudouridylation, ribosomal dysregulation, and a cell-cycle defect in the absence of telomere attrition. We therefore propose that this human disorder is the consequence of defective snoRNP pseudouridylation and ribosomal dysfunction.

RESUMEN

INTRODUCTION: Advanced intraocular retinoblastoma can be cured by enucleation, but spread of retinoblastoma cells beyond the natural limits of the eye is related to a high mortality. Adjuvant therapy after enucleation has been shown to prevent metastasis in children with risk factors for extraocular retinoblastoma. However, histological criteria and adjuvant treatment regimens vary and there is no unifying consensus on the optimal choice of treatment. METHOD: Data on guidelines for adjuvant treatment in European retinoblastoma referral centres were collected in an online survey among all members of the European Retinoblastoma Group (EURbG) network. Extended information was gathered via personal email communication. RESULTS: Data were collected from 26 centres in 17 countries. Guidelines for adjuvant treatment were in place at 92.3% of retinoblastoma centres. There was a consensus on indication for and intensity of adjuvant treatment among more than 80% of all centres. The majority of centres use no adjuvant treatment for isolated focal choroidal invasion or prelaminar optic nerve invasion. Patients with massive choroidal invasion or postlaminar optic nerve invasion receive adjuvant chemotherapy, while microscopic invasion of the resection margin of the optic nerve or extension through the sclera are treated with combined chemo- and radiotherapy. CONCLUSION: Indications and adjuvant treatment regimens in European retinoblastoma referral centres are similar but not uniform. Further biomarkers in addition to histopathological risk factors could improve treatment stratification. The high consensus in European centres is an excellent foundation for a common European study with prospective validation of new biomarkers.

RESUMEN

BACKGROUND: Presence of corneal cystine crystals is the main ocular manifestation of cystinosis, although controversial findings concerning the corneal layer with the highest density have been reported. The aim of this study was the analysis of the characteristics of crystal arrangement in different corneal layers and the assessment of corneal morphological changes with age. METHODS: A cross sectional study was carried out in three children and three adults who had nephropathic cystinosis and corneal cystine depositions. All patients underwent a comprehensive ophthalmological examination including best corrected distance visual acuity, slit-lamp examination, in vivo confocal microscopy and anterior segment optical coherence tomography. An evaluation of the depth of crystal deposits and crystal density in different corneal layers was also performed. Due to the low number of subjects no statistical comparison was performed. RESULTS: Anterior segment optical coherence tomography images revealed deposition of hyperreflective crystals from limbus to limbus in each patient. Crystals appeared as randomly oriented hyperreflective, elongated structures on in vivo confocal microscopy images in all corneal layers except the endothelium. In children the deposits occurred predominantly in the anterior stroma, while in adults, the crystals were mostly localized in the posterior corneal stroma with the depth of crystal deposition showing an increasing tendency with age (mean depth of crystal density was 353.17 ± 49.23 µm in children and it was 555.75 ± 25.27 µm in adults). Mean crystal density of the epithelium was 1.47 ± 1.17 (median: 1.5; interquartile range: 0.3-2.4). Mean crystal density of the anterior and posterior stroma of children and adults was 3.37 ± 0.34 (median: 3.4; interquartile range: 3.25-3.55) vs. 1.23 ± 0.23 (median: 1.2; interquartile range: 1.05-1.35) and 0.76 ± 0.49 (median: 0.7; interquartile range: 0.4-1.15) vs. 3.63 ± 0.29 (median: 3.7; interquartile range: 3.45-3.8), respectively. Endothelium had intact structure in all cases. Some hexagonal crystals were observed in two subjects. CONCLUSIONS: In vivo confocal microscopy and anterior segment optical coherence tomography confirmed an age-related pattern of crystal deposition. In children, crystals tend to locate anteriorly, while in adults, deposits are found posteriorly in corneal stroma.

RESUMEN

INTRODUCTION: Retinopathy of prematurity is a leading cause of childhood blindness around the world. AIM: The Department of Ophthalmology at the Semmelweis University and the Peter Cerny Neonatal Emergency and Ambulance Service started an innovative Premature Eye Rescue Program to reduce the non-essential transport of premature babies suffering from retinopathy of prematurity. METHOD: During the first 5 years 186 eyes of 93 premature babies were treated at the bedside with stage 3 retinopathy of prematurity in the primary hospitals. RESULTS: In this first 5-years period the authors reduced the number of transports of premature babies for laser treatment; 93 children avoided the unnecessary transport, saving altogether a distance of 21,930 kilometers for children, as well as the ambulance service. CONCLUSIONS: The Premature Eye Rescue Program offers a good and effective alternative for treatment of retinopathy in the primary hospitals. The authors propose the national extension of this program.

RESUMEN

PURPOSE: During life up to 70% of aniridia subjects develop aniridia-associated keratopathy (AAK). AAK is characterized by limbal stem cell insufficiency, impaired corneal epithelial cell differentiation and abnormal cell adhesion, which leads to centripetal spreading vascularization, conjunctivalization, and thickening of the cornea. Our aim was to examine the subbasal nerve plexus and central corneal stromal microstructure in subjects with congenital aniridia, using in vivo confocal laser scanning microscopy CLSM. METHODS: 31 eyes of 18 patients (55.6% males, mean age: 25.22 ± 16.35 years) with congenital aniridia and 46 eyes of 29 healthy subjects (41.4% males, mean age 30 ± 14.82 years) were examined using the Rostock Cornea Module of Heidelberg Retina Tomograph-III. At the subbasal nerve plexus, corneal nerve fiber density (CNFD), corneal nerve fiber length (CNFL), corneal total branch density (CTBD), and corneal nerve fiber width (CNFW) were analyzed using ACCMetrics software. Keratocyte density in the anterior, middle and posterior stroma was assessed manually. RESULTS: The CNFD (2.02 ± 4.08 vs 13.99 ± 6.34/mm2), CNFL (5.78 ± 2.68 vs 10.56 ± 2.82 mm/mm2) and CTBD (15.08 ± 15.62 vs 27.44 ± 15.05/mm2) were significantly lower in congenital aniridia subjects than in controls (p < 0.001 for all). CNFW was significantly higher in aniridia subjects than in controls (0.03 ± 0.004 vs 0.02 ± 0.003 mm/mm2) (p = 0.003). Keratocyte density was significantly lower in all stromal layers of aniridia subjects than in controls (p < 0.001 for all). Stromal alterations included confluent keratocytes, keratocytes with long extensions and hyperreflective dots between keratocytes in aniridia. CONCLUSIONS: Decrease in CNFD, CNFL, and CTBD, as well as increase in CNFW well refer to the congenital aniridia-associated neuropathy. The decreased keratocyte density and the stromal alterations may be related to an increased cell death in congenital aniridia, nevertheless, stromal changes in different stages of AAK have to be further analyzed in detail.

RESUMEN

BACKGROUND: The pathogenicity of the NPHS2 homozygous p.R229Q variant in steroid-resistant nephrotic syndrome (SRNS) is doubtful. While it has been reported in unaffected controls, it is enriched in patients with SRNS, suggesting pathogenicity. CASE-DIAGNOSIS/TREATMENT: A family with three members homozygous for the NPHS2 p.R229Q variant is presented: a 37-year-old patient who was diagnosed with proteinuria at age 7 months, focal segmental glomerulosclerosis (FSGS) at age 20 years, and end-stage renal disease (ESRD) at age 33 years, his 59 year-old father and his 40 year-old brother, both unaffected with no proteinuria. The affected son also harbors a heterozygous de novo, truncating PAX2 mutation (c.76dupG, p.V26Gfs*28), which can explain his chronic renal failure but which is rarely associated with FSGS. CONCLUSIONS: This family provides further evidence that homozygous p.R229Q in itself may not cause FSGS. Nevertheless, the rare association of FSGS to a PAX2 mutation may reflect the modifier effect of p.R229Q in the homozygous state. Such a modifier effect can also explain its enrichment in SRNS patients. Patients with homozygous p.R229Q should be screened for the causative mutation in a second gene.

RESUMEN

INTRODUCTION: Congenital aniridia is a rare disease, characterised by the complete or partial absence of the iris, but lesions may be present in all structures of the eye. OBJECTIVE: To determine the prevalence of ocular diseases in congenital aniridia by analyzing patients from a Hungarian centre. PATIENTS AND METHODS: Patients at the Department of Ophthalmology of Semmelweis University, examined between October 2005 and May 2022, have been included. After taking the patients' medical history, a detailed ophthalmological examination has been performed. RESULTS: Of the 82 patients in the database, 33 (age 25.69 ± 17.49 [5-59] years, 17 females [51.51%]) presented for examination and 65 eyes were examined. Nystagmus was found in 45 eyes of 23 patients (69.23%), and the patients' uncorrected distance visual acuity was 0.14 ± 0.128 (0.9 logMAR; 0.63-0.005). The aniridia-associated keratopathy was Grade 0 in 8 eyes (12.3%), Grade 1 in 10 eyes (15.38%), Grade 2 in 16 eyes (24.62%), Grade 3 in 4 eyes (6.15%) and Grade 4 in 25 eyes (38.46%). 30 eyes (46.15%) of 15 patients had secondary glaucoma, 6 eyes (9.2%) of 3 patients were glaucoma suspect. 8 eyes (12.3%) had a clear lens, 44 eyes (67.69%) had cataract, of which 22 (33.84%) were anterior cortical polar cataracts. 13 eyes (20%) were pseudophakic (PCL) and 7 eyes (10.77%) had lens dislocation or zonular insufficiency. Macular hypoplasia was found in 6 eyes of 3 patients (4.6%) and optic nerve head malformation in 2 eyes of 1 patient (3.03%). CONCLUSION: The ocular signs of congenital aniridia are aniridia-associated keratopathy, secondary glaucoma, cataract, macular and optic nerve head hypoplasia. Systematic collaboration of different ophthalmological specialties is required for the management and care of all these ocular abnormalities. Orv Hetil. 2023; 164(4): 148-155.

RESUMEN

INTRODUCTION: Congenital aniridia is a rare panocular disease that affects almost all eye structures leading in most patients to reduced visual acuity. Ophthalmological signs include aniridia-associated keratopathy, secondary glaucoma, cataract, macular and optic nerve head hypoplasia, nystagmus. Although the term aniridia-associated keratopathy has long been used in the literature, various staging proposals have been described. OBJECTIVE: To analyze aniridia-associated keratopathy stages, using available literature classifications, in patients with aniridia in Hungary. PATIENTS AND METHODS: We examined 65 eyes of 33 patients with congenital aniridia (age: 25.69 ± 17.49 [5-59] years, 17 females [51.51%]). We recorded the corneal status by slit-lamp examination and classified the corneal abnormalities according to the Mackman, Mayer, López-García and Lagali staging. RESULTS: According to Mackman's classification, 8 eyes (12.3%) were in stage 0, 0 eye in stage 1A, 38 eyes (58.46%) in stage 1B and 19 eyes (29.23%) in stage 2. According to Mayer, stage I included 8 eyes (12.3%), stage II 38 eyes (58.46%), stage III 5 eyes (7.7%), stage IV 7 eyes (10.77%) and stage V 7 eyes (10.77%). In López-García's classification, 8 eyes (12.3%) could not be grouped, 20 eyes (30.77%) were in stage 1, 18 eyes (27.7%) in stage 2 and 19 eyes (29.3%) in stage 3. Lagali's classification included 8 eyes (12.3%) in stage 0, 20 eyes (30.77%) in stage 1, 18 eyes (27.7%) in stage 2, 5 eyes (7.7%) in stage 3 and 14 eyes (21.54%) in stage 4. CONCLUSION: We recommend using Lagali's staging scheme for aniridia-associated keratoptahy due to its ease of use, detailed progression assessment, and treatment planning. In stage 1 according to Lagali, blood vessels cross the limbus by up to 1 mm, in stage 2 the central 2-3 mm of the corneal area is spared of blood vessels. When the blood vessels reach the center of the cornea, it is stage 3, followed by opaque, uneven corneal pannus in stage 4. Orv Hetil. 2023; 164(27): 1063-1069.

RESUMEN

INTRODUCTION: Aniridia is a rare congenital panocular disease associated with varying degrees of visual acuity impairment. OBJECTIVE: To assess the experiences of congenital aniridia patients in Hungary, with visual impairment using a questionnaire developed by the ANIRIDIA-NET. PATIENTS AND METHOD: Patients completed the Hungarian version of the 20-item ANIRIDIA-NET questionnaire with our assistance. The questionnaire covered demographic data, the most common complaints caused by the disease, the difficulties caused by low vision in different life situations and the frequency of low vision aids used in daily life. RESULTS: 33 subjects (17 female [51.51%] and 16 male [48.48%]), 16 (48.5%) children and 17 (51.5%) adults completed the questionnaire, with an age of 25.69 ± 17.49 years (5-59 years). Daily photosensitivity was reported by 27 (81.8%), dry eyes by 5 (15.2%), tearing by 4 (12.1%), fluctuating vision by 3 (9.1%), and eye pain by 2 (6.1%) subjects. The majority of respondents said that personal communication with schoolmates (16 [48.5%]) or colleagues at work (11 [33.3%]) never caused difficulties because of their visual impairment. 29 people (87.9%) never needed help with daily routines at home, 24 (72.7%) with getting to school/work and 17 (51.5%) with various activities. 29 people (87.8%) never used low vision aids for communication, 23 (69.7%) for travelling, 20 (60.6%) for participating in social activities, 18 (54.5%) for studying/work. CONCLUSION: Although aniridia is associated with reduced visual acuity, the majority of people with congenital aniridia, especially in childhood, manage to cope with personal communication and various life situations without difficulty, despite their eye complaints. Low vision aids can be an important aid for them as they grow into adulthood and as they age. Orv Hetil. 2023; 164(34): 1342-1349.

RESUMEN

Cystinosis is a rare lysosomal storage disease affecting amino acid metabolism, characterized by the accumulation and crystallization of cystine in various tissues, primarily in the eye and kidney. The major ophthalmic symptom is photophobia, which is related to the corneal deposition of cystine crystals. The light sensitivity significantly impairs the quality of life of the affected patients, thus, effective ophthalmic treatment to reduce the crystal density is very importance. In the current case report, we present the characteristic ocular clinical appearance and treatment options of cystinosis by reviewing the literature. A simple aqueous solution of cysteamine, which aids in the dissolution of crystals, has been widely used in topical treatment in the past, however, its therapeutic efficacy is debatable. Recently, a new viscous formulation of cysteamine has been proposed for ophthalmic treatment. For the treatment of corneal cystine crystals in our patient, the new viscous format of cysteamine has been applied, and therapeutic effects were recorded for a year. Applying the viscous cysteamine formulation, a marked and gradual decrease in photophobia was observed in our patient in the first year of the treatment. Anterior-segment optical coherence tomography and in vivo confocal microscopy represented a continuous decrease in the density of corneal crystals even from the first month of the treatment period. The aim of our case report is to present the ophthalmic symptoms of cystinosis and the results of the first clinical application of viscous formulation of cysteamin eye drops in Hungary in a cystinosis patient.

RESUMEN

Beta-tubulin 4B isotype is one of the subunits of microtubules encoded by TUBB4B gene on chromosome 9, which is responsible for the maintenance of microtubule stability. In humans, mutations in microtubule-encoding genes have been associated with several tubulinopathies with very heterogeneous symptoms. So far, only two missense mutations in TUBB4B gene have been found to have pathological implications in this disorder. Here we report a Hungarian family with three affected members, mother and her 12- and 14-year-old children, who suffer from ophthalmologic and hearing impairments probably due to c.1171C > T missense variant in the TUBB4B gene. The presented case is the second report, and unique in the literature because of three affected family members carrying the same mutation and the family provides evidence for a quite similar but not identical phenotype of LCAEOD in subjects carrying this mutation.

RESUMEN

Összefoglaló. Az Axenfeld-Rieger-szindróma ritka betegség. A közlemény bemutatja a klinikai megjelenési formáit, a diagnosztikus és terápiás lehetoségeket. A szemgolyó elülso szegmentumát érinto fejlodési rendellenességek vizsgálata a hagyományos biomikroszkópos vizsgálat mellett digitális kamerával is történhet, mely a csarnokzugi képleteket nagy nagyításban, éles képet mutatva tudja megjeleníteni. Az elülso szegmentum leképezését segíto optikaikoherencia-tomográfia és ultrahang-biomikroszkópia a fejlodési rendellenességnek és a csarnokvíz-elvezeto sönt tubusának vizsgálatára, megjelenítésére is alkalmas. A szemnyomást a gyermek kooperációjának függvényében többféle módon mérhetjük. A szabálytalan alakú, sokszor csak résnyi pupilla, valamint a szemnyomás-emelkedés miatt szemészeti beavatkozás lehet szükséges. A korai pupillaképzés az amblyopia megelozését, az antiglaucomás mutétek (trabeculectomia, hosszú tubusú sönt implantációja) pedig a látási funkciók megorzését szolgálják. A szemészeti mutéteket akár már néhány hónapos korban szükséges elvégezni altatásban. A maxillahypoplasia és a fogászati fejlodési anomáliák miatt kétirányú panoráma-röntgenfelvétel szükséges. Többlépcsos fogászati konzervatív és restoratív kezelés hozhat eredményt. A diagnózis felállítása és a kezelés is multidiszciplináris megközelítést igényel. Gyermekgyógyász, genetikus, kardiológus, fogász-szájsebész és gyermekszemész együttes munkája biztosíthat megfelelo eredményt. Orv Hetil. 2021; 162(5): 192-199. Summary. Axenfeld-Rieger syndrome is a rare disease. Our paper presents its clinical manifestations, diagnostic and therapeutic options. Due to maxillary hypoplasia and dental developmental anomalies, bidirectional panoramic radiography is required. Multi-stage dental conservative and restorative treatment can provide better results. In addition to traditional biomicroscopic examination, developmental abnormalities affecting the anterior segment of the eye can also be examined with a digital camera, which can display the angle of the anterior chamber at high magnification, with a sharp image. Anterior segment optical coherence tomography and ultrasound biomicroscopy are also suitable for the examination and display of developmental abnormalities and drainage shunt tubes. Intraocular pressure can be measured in several ways depending on the child's cooperation. Due to the irregular shape of the pupil, often with only a slit aperture, and an increase in intraocular pressure, ophthalmic intervention may be required. The pupilloplasty is important preventing amblyopia prevention and early glaucoma surgery (trabeculectomy, shunt implantation) helps to preserve visual function. Eye surgeries need to be performed under anaesthesia, sometimes at few months of age. Both diagnosis and treatment require a multidisciplinary approach. The joint work of a paediatrician, geneticist, cardiologist, dental-oral surgeon and paediatric ophthalmologist may provide a satisfactory result. Orv Hetil. 2021; 162(5): 192-199.

RESUMEN

PURPOSE: To assess the validity of wide-field digital imaging (WFDI) and telemedicine-based screening compared with examination by binocular indirect ophthalmoscopy (BIO) and to present some of the results from the first five years of telemedicine-based screening in the Premature Eye Rescue Program in Hungary. METHODS: We performed a retrospective analysis in two periods that aimed to assess (a) the validity of retinal digital imaging and (b) routine bedside screening. The validity was assessed in two neonatal intensive care units (NICUs), one in the First Department of Paediatrics and the other in the Second Department of Obstetrics and Gynaecology, Semmelweis University. The telemedicine-based WFDI (WFDI-TM) screening program was introduced in two phases. In the first phase (from 30 November 2009 to 8 August 2010), BIO and WFDI were performed by the same paediatric ophthalmologist (Group A). In the second phase (from 9 August 2010 to 29 March 2011), BIO was performed by the paediatric ophthalmologist, while retinal images were captured by a trained neonatal transport nurse practitioner (Group B). BIO screening was the reference method as a gold standard in both phases. RESULTS: During the validity assessment period 634 examinations were performed in 153 preterm infants. Overall, 76 babies were screened in Group A and 80 were screened in Group B. We found lower sensitivity and specificity in cases of any ROP (sensitivity 86%, specificity 99%) compared with those of treatment-requiring retinopathy of prematurity (TR-ROP) (both sensitivity and specificity 100%).In the Premature Eye Rescue Program between 1April 2011 and 31 March 2016, we used WFDI in 3035 infants (4589 procedures). Over this five-year period, 100 (9.6%) infants were treated by laser, and no child who received care in any of the Semmelweis University NICUs became blind from ROP. CONCLUSIONS: (a) WFDI-TM ROP screening is a useful and efficient approach, although it cannot completely replace BIO; (b) no ROP-related blindness developed among the screened preterm babies; and (c) WFDI-TM ROP screening can be implemented in the logistics of a neonatal emergency and ambulance team infrastructure with neonatal transport nurse practitioners as 'photographers'.

RESUMEN

PURPOSE: To report four cases of zoonotic ophthalmodirofilariasis infection caused by Dirofilaria repens in Hungary. METHODS: Four cases of ophthalmofilariasis have been treated at our department during the last 14 months. A subconjunctival moving worm was observed by slit lamp biomicroscopy in two cases. In one of these a living filaria was surgically removed, but the other disappeared. Red eye and migrating edema were the presenting signs in two cases. A biopsy taken from the subcutaneous masses disclosed D repens. RESULTS: Histopathologic or parasitologic examination identified a female D repens in every case. Laboratory alterations were not found. Symptoms subsided after treatment. CONCLUSION: The clinical presentation of filariasis is not always straightforward, and a high index of suspicion is necessary in cases presenting with orbital or periorbital inflammation. During the past 10 years the identification of locally acquired infections by D repens has increased in Hungary.

RESUMEN

Introduction: Idiopathic strabismus sursoadductorius is characterized by an overaction of the inferior oblique (IO) muscle, with elevation of the eye in adduction. This can result in chronic headache, eye pain, diplopia and abnormal head posture. Aim: Presentation of clinical results after graded recession of inferior oblique overaction (IOOA) in strabismus sursoadductorius. Method: During a period of 6 years (2012-2017) we performed a dosed transposition of IO muscle in 53 patients in the Department of Ophthalmology of the Semmelweis University and analyzed the clinical results retrospectively. The mean age was 12.8, min-max: 2-51 years. The transposition of the muscle (8 mm, 10 mm or maximal) was performed because of IOOA and was planned depending on the vertical deviation (VD) in maximal adduction. In case of maximal transposition, the insertion of IO was placed under the lateral part of the lower rectus muscle. We evaluated the squint angle in five positions of gaze preoperatively and postoperative 1 week, 1 month and 3-6 months. We examined best corrected visual acuity, binocular vision and complications after surgery. Results: Postoperatively 25 patients had acceptable stereopsis (Titmus 5). Visual acuity remained stable after surgery in all cases. The VD measured in maximal adduction changed with a decrease of 7.5° when 8 mm transposition was performed, and changed with a decrease to 12°, when maximal recession was performed. The mean reduction of VD was 17.8 prism dioptres (PD) after 1 week (p<0.01), 20.5 PD after 1 month and remained stable during a follow-up of 3-6 months. Conclusion: Graded recession of inferior oblique muscle is a suitable proposed procedure in patients with marked strabismus sursoadductorius. The rates of functional under- or overcorrection or other complications are low. Orv Hetil. 2019; 160(27): 1064-1069.

RESUMEN

PURPOSE: To analyse current clinicopathological enucleation indications in a large third-referral centre in a developed country (Hungary) over a period of 12 years. METHODS: Retrospective review was performed on 547 enucleated eyes of 543 patients (48.6% males, age 52.7 ± 24.5 years) who were operated on between 2006 and 2017 at the Department of Ophthalmology of Semmelweis University, in Budapest, Hungary. For each subject, clinicopathological data, including patient demographics, indications for enucleation, B-scan ultrasound reports, operative details, and histopathological analyses, were reviewed. Primary enucleation indications were classified into trauma, tumours, systemic diseases, surgical diseases, infections or inflammations, miscellaneous diseases, and unclassifiable groups. Clinical immediate enucleation indications were classified as tumours, atrophia or phthisis bulbi, infection or inflammation, painful blind eye due to glaucoma, acute trauma, threatening or spontaneous perforation, cosmetic causes, and expulsive bleeding. RESULTS: The most common primary enucleation indications were tumours (47.3%), trauma (16.8%), surgical diseases (15.7%), infection or inflammation (11.6%), systemic diseases (5.1%), miscellaneous diseases (2.0%), and unclassifiable diseases (1.5%). Clinical immediate enucleation indications were tumours (46.1%), atrophia or phthisis bulbi (18.5%), infection or inflammation (18.5%), painful blind eye due to glaucoma (11.2%), acute trauma (3.7%), threatening or spontaneous perforation (1.3%), cosmetic reasons (0.5%), and expulsive bleeding (0.4%). CONCLUSIONS: Intraocular tumours represent the most common clinicopathological indication for ocular enucleation in our study population. Following ocular trauma and systemic diseases, the rate of enucleation decreased in the last decade, compared to those previously reported in other developed countries. However, changes were not observed for surgical diseases, infectious and inflammatory causes, or for miscellaneous and unclassified diseases. Orbital implant financing should be increased to ensure better postoperative aesthetic rehabilitation, following enucleation in Hungary.

RESUMEN

We report orbital involvement as an initial manifestation of acute myeloid leukemia in a 57-year-old woman. The patient presented with painful proptosis and limited ocular motility. Orbital computed tomography revealed bilateral homogeneous masses. Orbital biopsy was performed on the right side; and histopathology disclosed a myelocytic tumour. Despite treatment using irradiation and chemotherapy, the patient died eleven months after presentation. There appear to be only a few previous reports of acute myeloid leukemia cases presenting with orbital involvement, and most cases occurred in children. This very rare condition has a poor survival prognosis, even with radiation treatment and chemotherapy.
