Sonographic and ophthalmic assessment of optic nerve in patients with idiopathic intracranial hypertension: A longitudinal study. J Neurol Sci 2021; 430:118069. [PMID: 34525433 DOI: 10.1016/j.jns.2021.118069] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 09/01/2021] [Accepted: 09/02/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND To assess the validity of neurosonological parameters (transorbital sonography (TOS)) for detection and monitoring of patients with idiopathic intracranial hypertension (IIH). METHODS Prospective, single-center, case-controlled study in 25 patients with IIH and 19 controls. Visual parameters of papilledema, visual acuity, computerized static threshold perimetry, fundus examination, and neurosonological parameters of papilledema/optic disc elevation (ODE), optic nerve sheath diameter (ONSD) and optic nerve diameter (OND) were recorded at baseline and only for patients with IIH again within 6 months. RESULTS ONSD was significantly enlarged among individuals with IIH (6.2 ± 0.73 mm) compared to controls (4.99 ± 0.54 mm; p < 0.001). Bilateral ODE was found in 36/50 eyes in patients at their initial visit and in none of the controls. Re-evaluation 6 months later showed a significant reduction of ONSD (6.0 ± 0.7 mm; p = 0.024) and ODE (0.2 (0-1) mm; p ≤0.001). Best corrected visual acuity (BCVA) and square root of lost variance (sLV) remained stable. Headache intensity (Numeric rating scale, NRS) improved significantly p < 0.001. When compared to patients with first diagnosed IIH (n = 18), the subset of patients with preexisting IIH with acute relapse (n = 7) showed persistent but reduced levels of ICP increase. They also presented significant decrease of BVCA (p = 0.01) and mean defect (MD) (p = 0.012). Re-evaluation 6 months later showed significant change in ODE in both groups. CONCLUSIONS Our study confirmed that TOS and ophthalmological parameters are a valuable and non-invasive method to detect and monitor elevated ICP in IIH.

An attempt to optimize the outcome of penetrating keratoplasty in congenital aniridia-associated keratopathy (AAK). Int Ophthalmol 2021; 41:4091-4098. [PMID: 34324101 PMCID: PMC8572819 DOI: 10.1007/s10792-021-01982-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Accepted: 07/16/2021] [Indexed: 11/30/2022]
Abstract
Purpose To propose an optimized microsurgical and medical approach to reduce the risk of complications after penetrating keratoplasty (PKP) in patients with aniridia-associated keratopathy (AAK). Methods Retrospective observational case series of 25 PKP performed in 16 patients with AAK. Preoperative indications were endothelial decompensation and vascularized scars (68%) or graft failure (32%) due to limbal stem cell deficiency. The optimized approach included a combination of a small corneal graft size (around 7.0 mm), interrupted 10–0nylon sutures, simultaneous AMT as a patch, large bandage contact lens, temporary lateral tarsorrhaphy, postoperative autologous serum eye drops, and systemic immunosuppression. Main outcome measures included: visual acuity, transplant survival, and complications encountered during follow-up of 107 weeks on average. Results A complete modified keratoplasty scheme was used in 10 of 25 PKP (group 1), while at least one of the modifications was missing in the other 15 PKP (group 2). After 8 weeks of follow-up, the epithelium was closed in 23 eyes. Visual acuity improved in 19 eyes at 6 months of follow-up, and remained stable in six eyes. None of the eyes showed a decrease in visual acuity. At the last post-operative follow-up, this visual improvement persisted in 14 eyes and graft survival rate after 156 weeks (3 years) was 69% in group 1 versus 44% in group 2 (p = 0.39, log-rank test). Secondary corneal neovascularization (8%), scarring (4%), ulcer (4%), or graft rejection (8%) happened mostly in the second group which was missing at least one of the suggested modifications. Conclusions PKP in congenital aniridia must be considered as a high-risk keratoplasty. An optimized therapeutic approach seems to be promising in order to reduce the postoperative complication rate in these most difficult eyes.

Abnormal neovascular and proliferative conjunctival phenotype in limbal stem cell deficiency is associated with altered microRNA and gene expression modulated by PAX6 mutational status in congenital aniridia. Ocul Surf 2020; 19:115-127. [PMID: 32422284 DOI: 10.1016/j.jtos.2020.04.014] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2019] [Revised: 03/09/2020] [Accepted: 04/26/2020] [Indexed: 12/18/2022]
Abstract
PURPOSE To evaluate conjunctival cell microRNA (miRNAs) and mRNA expression in relation to observed phenotype of progressive limbal stem cell deficiency in a cohort of subjects with congenital aniridia with known genetic status. METHODS Using impression cytology, bulbar conjunctival cells were sampled from 20 subjects with congenital aniridia and 20 age and sex-matched healthy control subjects. RNA was extracted and miRNA and mRNA analyses were performed using microarrays. Results were related to severity of keratopathy and genetic cause of aniridia. RESULTS Of 2549 miRNAs, 21 were differentially expressed in aniridia relative to controls (fold change ≤ -1.5 or ≥ +1.5). Among these miR-204-5p, an inhibitor of corneal neovascularization, was downregulated 26.8-fold in severely vascularized corneas. At the mRNA level, 539 transcripts were differentially expressed (fold change ≤ -2 or ≥ +2), among these FOSB and FOS were upregulated 17.5 and 9.7-fold respectively, and JUN by 2.9-fold, all being components of the AP-1 transcription factor complex. Pathway analysis revealed enrichment of PI3K-Akt, MAPK, and Ras signaling pathways in aniridia. For several miRNAs and transcripts regulating retinoic acid metabolism, expression levels correlated with keratopathy severity and genetic status. CONCLUSION Strong dysregulation of key factors at the miRNA and mRNA level suggests that the conjunctiva in aniridia is abnormally maintained in a pro-angiogenic and proliferative state, and these changes are expressed in a PAX6 mutation-dependent manner. Additionally, retinoic acid metabolism is disrupted in severe, but not mild forms of the limbal stem cell deficiency in aniridia.

Abstract
Congenital aniridia is a severe autosomal dominant congenital panocular disorder, mainly associated with pathogenic variants in the PAX6 gene. The objective of the study was to investigate the mutational and clinical spectra of congenital aniridia in a cohort of 117 patients from Russia. Each patient underwent detailed ophthalmological examination. From 91 unrelated families, 110 patients were diagnosed with congenital aniridia and 7 with WAGR syndrome (Wilms tumor, Aniridia, Genitourinary anomalies, and mental Retardation syndrome). The clinical presentation in aniridia patients varied from the complete bilateral absence of the iris (75.5%) to partial aniridia or iris hypoplasia (24.5%). Additional ocular abnormalities were consistent with previous reports. In our cohort, we saw a previously not described high percentage of patients (45%) who showed non-ocular phenotypes. Prevalence of deletions coherent with WAGR syndrome appeared to be 19.4% out of sporadic patients. Among the other aniridia cases, PAX6 deletions were identified in 18 probands, and small intragenic changes were detected in 58 probands with 27 of these mutations being novel and 21 previously reported. In 3 families mosaic mutation was transmitted from a subtly affected parent. Therefore, PAX6 mutations explained 96.7% of aniridia phenotypes in this study with only 3 of 91 probands lacking pathogenic variants in the gene.

[PONV after strabismus surgery : Risk adapted prophylaxis?]. Anaesthesist 2016; 65:507-13. [PMID: 27295547 DOI: 10.1007/s00101-016-0183-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2015] [Revised: 03/10/2016] [Accepted: 04/19/2016] [Indexed: 11/24/2022]
Abstract
BACKGROUND Following strabismus surgery, patients frequently develop variable degrees of postoperative nausea and vomiting (PONV). These symptoms cause discomfort and result in serious complications such as intramuscular bleeding and subconjunctival hemorrhage. In children long lasting PONV can lead to and electrolyte imbalance and dehydration. A prolonged course of recovery is the consequence. For the hospital, PONV can also involve negative economic impacts because of a damaged public reputation of the institution. There is still an ongoing debate on wether prophylaxis of PONV is necessary and how the prophylaxis of PONV should be performed. On one hand, there are proponents of a liberal prophylaxis. These intend to treat almost all patients regardless of their individual risk for PONV. On the other hand, opponents point out that every medication has to be indicated individually. In their view, risk scores should be the base of a risk-adapted approach. OBJECTIVES The aim of the study was to reduce the frequency of PONV by using an anesthetic technique adapted to the individual risk for PONV. Until now, all trials studying the efficiency of a score-based antiemetic prophylaxis were performed on adult patients. In this study, a risk-adapted approach was evaluated on children for the first time. PATIENTS AND METHODS In 92 patients, the incidence of PONV was analyzed after strabismus surgery. Before surgery we evaluated the risk factors for PONV according to the POVOC score in children (n = 45, 49 %) and the Apfel's score in adults (n = 47, 51 %). Patients with 0-2 risk factors received a balanced anesthesia (n = 47, 51 %). Those with 3-4 risk factors were operated in total IV anesthesia (TIVA) with propofol (n = 45, 49 %). In addition, as an antiemetic prophylaxis, 0.15 mg/kg dexamethason and 0.1 mg/kg ondansetron were applied in the latter patients. we documented the symptoms and severity of PONV 2, 6 and 24 h after surgery by means of a standardized questionnaire for PONV (Wengritzky-Score). RESULTS The incidence of PONV was 17 % (n = 16) in all of the patients. The incidence in low-risk patients receiving a BA without prophylaxis were 21 % in adults and 38 % in children. Of the patients at high risk for PONV receiving the multimodal antiemetic approach 8 % (adults) and 9 % (children) suffered from PONV. The combination of TIVA and antiemetics could reduce the incidence of PONV compared to the predicted values in a clinically relevant manner (OR = 0.26, KI: 0.76-0.87). CONCLUSION The overall incidence could be reduced to a level below 20 %. Particularly in patients with a high risk of PONV, TIVA could clearly reduce the incidence. However, the incidence in patients with 2 risk factors is still high (30-39 %). Therefore, it is important to reconsider the effort involved with risk screening and individually adapting anesthesia. Risk stratification means a pre- and perioperative effort. Therefore, we advocate a more liberal approach for PONV prophylaxis.

Abstract
Congenital glaucoma is a disease potentially leading to blindness in children. It poses a diagnostic and therapeutic challenge even though new knowledge has been acquired and a sufficient understanding of the pathogenesis has been gained. New discoveries, such as the exact time when Schlemm's canal develops could lead to a prenatal diagnosis and therefore surgical intervention so that other complications including blindness can be avoided. This case report demonstrates that an early prenatal eye screening with ultrasound (after approximately 30 weeks of pregnancy) would be desirable in order to diagnose buphthalmus early and to plan postnatal surgery.

Abstract
A 4-year-old girl presented to our department with a pain and symptom-free elevated intraocular pressure (IOP) of 44 mmHg in both eyes and with enlarged corneal diameters. Megalocornea, buphthalmos and anterior megalophthalmos were discussed as differential diagnoses. Due to age-related normal morphological, functional and electrophysiological results of the optic nerve head and a very deep anterior chamber, anterior megalophthalmos was diagnosed. No topical treatment was initiated and close ophthalmological surveillance control was recommended. To the best of our knowledge megalophthalmus anterior has not up to now been described as associated with a pathological sensitivity to minor changes in lid muscle tension causing a sudden increase of IOD.

Abstract
There is a lot of uncertainty concerning intraocular lens (IOL) implantation for pediatric cataracts. The appropriate age which ocular abnormalities are contraindications and according to which formula IOL should be calculated are controversial. In addition to the imperative of identifying postoperative complications, such as secondary cataract formation and secondary glaucoma in a sufficiently timely manner, a modern management of aphakia with refractive compensation and occlusion is necessary. Some easy rules can help prevent pitfalls.

Abstract
Despite progress in microsurgical treatment, pediatric cataracts still imply potential risks for pathological unilateral or bilateral visual and binocular development. Surgical approaches have changed fundamentally over the last 30 years which are directly associated with modifications in the postoperative care. Due to these parallel developments a continuous dynamic process arises between anterior segment surgeons and pediatric ophthalmologists so that only small case series exist which try to combine both subspecialties because until now it was not possible to gather enough experience with a single linear approach. The first article of this two part series will explain the variability of the disease and surgical approaches and the second part will try to convey a linear approach for the postoperative care.

Abstract
This article describes the clinical presentation of the most common congenital optic disc findings: optic nerve hypoplasia, optic disc cupping and pediatric optic atrophy. Particular emphasis is placed on the often difficult question: is it a physiological variant or is it pathological? Do I need further investigations? Pragmatic clinical hints are given to enable ophthalmologists to recognize normal variants with greater certainty but also not to overlook congenital optic nerve pathologies. Congenital anomalies of the optic nerve (head) are more common than half a century ago. They can affect the visual development and thus the general infantile development to a large extent if presenting bilaterally. They can occur isolated, with other ocular pathologies and/or accompanied by systemic diseases or syndromes, such as septo-optic dysplasia, albinism, prematurity, small for gestational age birth, as well as due to toxic exposure during pregnancy (e.g. drugs, alcohol and maternal diabetes). In addition to clinical illustrations to distinguish between physiological variants and pathologies of the optic nerve head, the different diagnostic and therapeutic options depending on the age of presentation of the infant are outlined. The reader will obtain some guidelines for distinguishing congenital and acquired optic nerve pathologies. The focal point of the present paper is with infants aged 0-2 years where many diagnostic imaging and psychophysical techniques cannot be applied. Therefore, this age group is the most difficult to correctly discriminate between physiological and pathological findings and to decide whether further diagnostic and/or treatment steps are necessary.

Abstract
In this article we report on two patients with arachnoid cysts previously treated by shunt implantation presenting with clinical signs of an increased intracranial pressure i. e., papilledema, headache and nausea. Repeated MRI scans showed no alteration of the cerebrospinal fluid circulation and no space-occupying effect of the cysts. Although neuroimaging showed no signs of increased intracranial pressure, neurosurgical exploration was performed and revealed a distinctly increased pressure in both arachnoid cysts. After replacement of the shunt a prompt reduction of papilledema and relief of symptoms was observed.

Abstract
In spite of albinism being one of the visual impairments which has been known for over a century, it has only been known for a few decades that albinism is correlated to severe cerebral morphological developmental alterations. The increasing knowledge about the role of melanin in the development and orientation of cerebral neurons not only renders more insight into albinism, but also a greater insight in the physiological neuronal and cerebral development in man. Concerning the morphological and visual phenotype there are new clinical findings which enlarge the known spectrum of albinism. In a representative group of 506 persons with oculocutaneous and ocular albinism who are in care at the Department of Ophthalmology at the University of Saarland (UKS), we present a staging of morphological findings of the iris, retinal pigment epithelium and macula, and of the optic nerve head which has been in use for 10 years. Albinism may present with a remarkably mild ocular phenotype and a near to normal functional phenotype. We present correlations between molecular genetic types of albinism, ocular phenotype and visual function. Of great importance concerning later visual acuity is the dysplasia of the optic nerve head (ONH), which is a frequent finding in albinism. The appearance of the ONH should always be included in any clinical description of an albinism patient. It is highly possible that due to a moderate phenotype there are still many patients who have not been diagnosed yet. Visual acuity of 30/20 to 20/20 and no nystagmus do not rule out albinism. In addition, when performing albino VEPs in phenotypically normal children with infantile strabismus, small ONHs, but normal visual acuity and no nystagmus, the classical atypical chiasmal crossing is sometimes found. Therefore, the number of persons having undiagnosed albinism is probably quite high, perhaps there even is a very broad transition zone from normal to albinotic.

Abstract
Albinism comprises a heterogeneous group of nonprogressive genetic disorders characterized by the absence of pigmentation in the skin, hair, and/or eyes. Hypopigmentation or complete lack of pigmentation is caused by an enzyme deficiency involving the production, metabolism, or distribution of melanin. Clinically, oculocutaneous and ocular types, as well as syndromes associated with albinism resulting from mutations in at least 14 genes, are distinguishable. Most frequent is oculocutaneous albinism (OCA), which is subdivided nowadays into four forms, OCA 1-OCA 4. OCA is inherited as an autosomal recessive trait. Clinical differentiation of OCA types is difficult due to the observed range of phenotypic variation. Thus, genetic analysis may be helpful with respect to a precise diagnosis. Sequencing of the four genes associated with OCA detects variations in approximately 60-70% of German patients with albinism. The majority of German patients are affected by OCA 1 resulting from mutations in the gene for tyrosinase, the key enzyme in the synthesis of melanin pigment. Worldwide, OCA2 is the most frequent form of albinism.

Abstract
Albinism is associated with a misrouting of fibers at the optic chiasm where the majority of fibers cross to the contralateral side. The cause of this abnormal decussation pattern reflects a disturbance of cell cycle regulation in the development of the retina which is in part controlled by melanin. Growing axons from retinal ganglion cells therefore arrive later than usual at the optic chiasm and are misrouted contralaterally. This atypical decussation leads to morphological changes of the optic chiasm including a reduced chiasm width with larger angles between optic nerves and tracts which can be shown by magnetic resonance imaging.

Abstract
BACKGROUND Sinus vein thrombosis is a rare intracerebral complication of mastoiditis. We report on the clinical ophthalmologic symptomatology of this secondary illness. PATIENTS AND METHODS HISTORY two young female patients, aged 14 and 3.5 years, presented at our pediatric ophthalmology section due to diplopia. Both girls had suffered 1-2 weeks earlier from otitis media, which had been treated with antibiotics. Other neurological symptoms were not reported. CLINICAL COURSE Best corrected visual acuity was 20/20 OD/OS in both patients. Ocular alignment revealed a bilateral abduction deficit in the 14-year-old girl and a monolateral abduction deficit of the right eye in the younger patient. Ophthalmoscopic examination evidenced bilateral papilledema in both patients. Magnetic resonance tomography and magnetic resonance angiography showed mastoiditis and thrombosis of the sigmoid and transverse sinuses. THERAPY Following mastoidectomy, high-dose antibiotic therapy, and full-dose heparin therapy, rapid improvement occurred. CONCLUSIONS Thrombosis of the sigmoid sinus following mastoiditis is a rare but severe complication of middle ear inflammation. Immediate surgical and antibiotic therapy is necessary. Symptoms can possibly occur even when the primary focus seems to resolve.

Abstract
BACKGROUND Retinal microvascular abnormalities associated with multiorgan disease may be observed in a number of systemic illnesses and syndromes. PATIENTS Two sisters with identical signs of a hereditary cerebroretinal vasculopathy (occlusive retinal angiopathy--cerebral vasculopathy--microcephalus) were treated at the University Hospital of Saarland. COURSE Photocoagulation for treatment of neovascular complications secondary to retinal ischemia was performed. In one eye a vitrectomy became necessary because of persistent vitreal hemorrhage. One sister died because of non treatable intracranial hypertension at the age of 22 years. CONCLUSIONS Interdisciplinary work-up is important in patients with cerebroretinal disease. Neuropathologic evaluation including brain biopsy and neuroimaging plus ophthalmoscopy and pedriatic findings lead to the diagnosis of this rare hereditary, in this case most likely autosomal recessive condition. Photocoagulation may limit neovascular complications secondary to retinal ischemia. A specific form of treatment has, however, not yet been found.

Abstract
BACKGROUND Incontinentia pigmenti (IP; Bloch-Sulzberger syndrome) is an inherited disorder of skin pigmentation that is associated with skin (100%), dental (90%), skeletal (40%), central nervous (40%) and ocular (35%) abnormalities. The pathogenesis is not yet known. The disease is usually seen in females, as it is an X-linked dominantly inherited disease which is lethal in males. PATIENT PRESENTATION We present a 9-year-old girl with the classical general and ocular signs of IP. She presented in early childhood with inflammatory vesicular skin changes which changed into pigmented skin alterations especially on the trunk. Ocular findings were microphthalmia and retrolental mass formation in one eye and retinal pigmentary changes in the other. In our patient, the spontaneous mutation may have been caused by the family's close neighbourhood to Semipalatinsk, Kasachstan, where regular nuclear tests took place very shortly before the pregnancy with our patient began. DISCUSSION Ocular involvement is described in about a third of persons affected with IP. A nearly consistent and pathognomonic finding is a pigment retinopathy (mottled diffuse hypopigmentations). A further consistent finding are abnormalities of peripheral retinal vessels with areas of non-perfusion in the outer retina. The retinal pigment epitheliopathy and the abnormalities of retinal vessels are thought to be the underlying pathognomonic findings, with all other ocular signs being secondary (cataract, leucocoria, optic atrophy, strabismus, nystagmus and microphthalmus). Exudative retinal detachment occurs only in a minority, usually in very early childhood, when the skin lesions are exudative as well. IP patients should, however, be clinically observed regularly because of their retinal pigmentary changes.

Abstract
BACKGROUND The mucopolysaccharidoses (MPS) are an inhomogeneous group of disorders of errors in the carbohydrate metabolism with severe ocular involvement (corneal opacification, retinal degeneration, optic atrophy). PATIENT PRESENTATION We report on a boy aged 12 years, with Morquio A (MPS IV A) syndrome. Ocular findings: progressive pseudoexophthalmus due to shallow orbits, increasing corneal stromal clouding, intermittent dissociated manifest nystagmus of the left eye, nyctalopia. Visual acuity OD cc = 0.16, OS cc = 0.05. Electrophysiology: changes suggesting a symptomatic tapetoretinal degeneration and optic atrophy. TREATMENT AND COURSE OF DISEASE: OS: perforating keratoplasty. Postoperative improvement of visual acuity to 0.25 for nearly a year, followed by progressive reopacification of the corneal graft. Both eyes: progressive signs of tapetoretinal degeneration and optic atrophy. Visual acuity now reduced to OD 0.05, OS 0.1. CONCLUSIONS Success of a keratoplasty is limited by (1) reopacification of the cornea, (2) visual impairment due to (a) retinal degeneration and (b) optic atrophy. The indication for perforating keratoplasty has to be thought about very carefully in these multimorbid patients. In our patient, beside progressive visual impairment there is a progressive deafness which dominates his social and school life. Attending school is severely complicated by the double handicap. Perforating keratoplasty enabled the boy to attend a school for physically handicapped without a special low-vision care for another year. Progressive visual loss without further treatment options now renders optical and electronic low-vision aids necessary. Although the time of improved visual acuity lasted less than a year, we think patients with a life expectancy of less than 20 years should have every possible improvement of their situation - even if it does not last permanently. We therefore propose perforating keratoplasty in spite of insufficient long-term results.

Abstract
BACKGROUND The combination of anisomyopia and myelinated nerve fibres of the higher myopic eye is often correlated with a deep and therapy-refractive amblyopia. As the cause for the entity anisomyopia/myelinated nerve fibres a disorder of development on the level of the lamina cribrosa during embryo genesis has been suggested in the literature. There are only very few reports on a successful therapy of the amblyopia that goes along with anisomyopia/myelinated nerve fibres. PATIENTS We report on six patients, aged 6 to 28 years, who presented with anisomyopia, myelinated nerve fibres and deep amblyopia in the higher myopic eye. The four younger patients were enrolled into a therapeutic trial with contact lens correction and occlusion. RESULTS The six patients presented with varying degrees of anisomyopia between -3.5 D and -18.5 D. In addition, in two patients we found a microstrabism and in three patients an exotropia. In spite of consistent occlusion and full optical correction in the four patients who underwent therapy visual acuity did not improve to more than 0.4 (1x microstrabism, 2x exotropia, 1x no squint--best visual recovery in the patient with microstrabism). CONCLUSIONS The combination of unilateral high myopia and myelinated nerve fibres represents a special entity which usually is correlated with a deep amblyopia. The amblyopia is nearly refractive to therapy even under consequent therapy with contact lenses and prolonged occlusion. Nevertheless one should try to treat the amblyopia to achieve at least a small improvement. The goal is to diagnose this constellation already in the first two years of life. As our cases show occlusion therapy at this age can lead at least to a limited improvement of visual acuity.

Abstract
BACKGROUND There are controversies concerning the necessity of pre-school vision screening. AIM OF THE STUDY evaluation of the prevalence of pathologic ophthalmologic findings in kindergarten children. MATERIALS AND METHODS 1030 families were offered a vision screening. Of these, a total of 948 children, aged 3 to 6 years, voluntarily underwent a screening for strabismus, amblyopia and refractive anomalies. The examination was performed in the kindergarten in the absence of the parents. METHODS OF EXAMINATION: A questionnaire concerning general and ophthalmologic history of the child and of the family was evaluated. Visual acuity, cover-uncover-test, Lang-stereotest, retinoscopy, ophthalmoscopy (undilated pupils) were performed and the glasses were evaluated. RESULTS The screening was highly accepted by the parents and 92% of the families (n = 948) took part. The compliance of the children was very good. A total of 38.7% (n = 381) of the children showed one or more abnormal parameters. 21.4% (n = 229) showed a reduced visual acuity. Strabismus was found in 3.7%. Half of the children with abnormal findings already had had a vision screening, but only 25% had received ophthalmologic treatment. Of those who possessed glasses, 25% came without them, and another 25% had a reduced visual acuity even with their glasses. The main problems were many false-positive results and high costs. CONCLUSIONS Ophthalmologic and orthoptic screening in kindergarten is technically easy and conclusive in experienced hands. Ideas to reduce costs and to avoid overreferrals are an age-related lowering of the visual acuity limit and a rescreening of suspected children in a screening-setting a second time before sending them to an ophthalmologist. Another possibility to reduce costs would be to perform examinations not by ophthalmologists but by "screening-orthoptists" who should be trained in retinoscopy and ophthalmoscopy.

Abstract
BACKGROUND The aim of the study was the evaluation of how ophthalmological diagnoses and the proportion of multiply handicapped children has changed within the last 20 years at a state school for visually handicapped and blind children. PATIENTS AND METHODS A profile investigation was conducted on all 105 children at the Landesschule für Blinde und Sehbehinderte des Saarlandes and compared to the results of an examination from 1975. RESULTS The predominant ophthalmological diagnoses were: optic atrophy (17.5%), ocular albinism (11.9%), scar-stage IV and V of retinopathy of prematurity (11.1%), as well as tapetoretinal dystrophies with related syndromes (8.7%) and myopia magna (7.9%). Blind: 10.3% (1975: 36.4%); visually handicapped: 47.1% (1975: 49.2%); multiply handicapped: 42.5% (1975: 14.4%). CONCLUSIONS (1) The diseases that dominated in earlier years in schools for the visually handicapped have become rare (cataract, aphakia, buphthalmia, macular dystrophy--all less than 5%); (2) the proportion of completely blind pupils has become much smaller; (3) there is an increasing tendency to educate visually handicapped pupils in regular schools with integrative aids; (4) there is also an increasing proportion of multiply handicapped children (school and kindergarten: 42%, early patronage 74%).
