Abstract
Pediatric corneal transplant is a highly demanding and technically challenging procedure for the cornea surgeon in today's era. These cases pose unique challenges in clinical and surgical management. The indications of pediatric corneal transplant can be therapeutic, tectonic, optical, and cosmetic. Pediatric patients undergoing corneal transplants are at a high risk of graft infection, failure, rejection, dehiscence, and amblyopia due to young age, robust immune system, increased incidence of trauma, and compliance issues. The other factors contributing to graft failure can be allograft rejection, secondary glaucoma, corneal vascularization, multiple surgeries, vitreous prolapse, and lack of treatment compliance. A successful corneal transplant in children depends on meticulous preoperative evaluation, uneventful surgery, the expertise of a corneal surgeon, and regular and timely postoperative follow-up. Therapeutic and optical penetrating keratoplasty are the most commonly performed transplants in children. However, with the advancements in surgical technique and management protocol, the current focus has shifted toward lamellar keratoplasty. Lamellar keratoplasty offers early visual recovery and potentially fewer complications. Visual rehabilitation through corneal transplant in otherwise blind eyes can be a boon for the children. Recently, keratoprostheses have been promising in children with multiple graft failures. The current review gives insights into epidemiology, etiology, indications, clinical characteristics, investigations, management options, recent advances, and the future of pediatric corneal transplants. As surgical techniques continue to grow and comprehension of pediatric corneal transplants is improving, we can safeguard these eyes with the best possible anatomical and functional outcomes.

Abstract
(1) Background: To analyze the indications, graft survival, and graft failure-related risk factors of repeat penetrating keratoplasty (RPK) in children. (2) Methods: In this case series, children younger than 12 years who received RPK at Beijing Tongren Hospital were reviewed. The indications for RPK, postoperative complications, and graft survival were analyzed. The analysis of the potential variables associated with graft survival was performed using Cox proportional hazards regression. (3) Results: A total of 30 RPK eyes of 29 children were included in this study. The mean follow-up time was 26.98 ± 18.75 months. The most common indication for RPK was a vascularized corneal scar (86.67%). Postoperative complications occurred in 27 eyes (90%), including immune rejection (46.67%), epithelial defects (36.67%), and glaucoma (26.67%). About 60% of the regrafts remained clear one year after RPK, while the overall graft survival rate was 30% at the last visit. The most common cause of regraft failure was irreversible immune rejection (8/21). The significant risks of graft failure included an age of less than 60 months at surgery (p = 0.009), corneal vascularization (p = 0.018), and a postoperative epithelial defect (p = 0.037). (4) Conclusions: A vascularized corneal scar is the most common indication of RPK in children. Immune rejection is the most prevalent complication, and irreversible immune rejection always causes regraft failure.

Preoperative geometric parameters predict the outcome of lamellar keratoscleroplasty in patients with limbal dermoids. Int Ophthalmol 2023:10.1007/s10792-022-02623-9. [PMID: 36640245 DOI: 10.1007/s10792-022-02623-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 12/20/2022] [Indexed: 01/15/2023]
Abstract
PURPOSE To find preoperative simple geometric parameters to predict the outcome of lamellar keratoscleroplasty in patients with corneal limbal dermoids. METHODS We retrospectively analyzed the data of 30 patients with limbal dermoids who underwent lamellar keratoscleroplasty and were followed up for more than 6 months. Seven geometric parameters were used to analyze the relationship with postoperative visual acuity, astigmatism, and scar formation and investigated for their influence on postoperative outcome. These seven parameters included the cornea-invaded area of dermoid, dermoid area, the cornea-invaded length of dermoid, the corneal limbus invaded length of dermoid, dermoid size, bed size, graft size. Furthermore, we divided patients with corneal limbal dermoids into amblyopia group and non-amblyopia group, and analyzed the clinical characteristics of the amblyopia group. RESULTS The mean age of the patients at surgery was 10.6 ± 5.83 years. The 7 geometric parameters, preoperative and postoperative astigmatism of the amblyopia group were higher than those of the non-amblyopia group (all P < 0.05). Among the geometric parameters analyzed, the r coefficients between the cornea-invaded length of dermoid and postoperative visual acuity and astigmatism were the highest (r = 0.854, r = 0.714). The r coefficient between the corneal limbus invaded length of dermoid and the postoperative scar was the highest (r = 0.375). The r coefficient between age and postoperative steroid-induced high intraocular pressure was the highest (r = - 0.416). In univariate regression analysis, the cornea-invaded length of dermoid was significantly correlated with postoperative visual acuity (β = 0.270, P < 0.001) and postoperative astigmatism (β = 1.362, P < 0.001). Among the geometric parameters analyzed, the cornea-invaded length of dermoid had best stratified patients in grouping with or without amblyopia (cutoff > 2.24). CONCLUSION The cornea-invaded length of dermoid was the most important related factor of postoperative visual acuity, astigmatism, and amblyopia. The corneal limbus invaded length of dermoid was the most important related factor of postoperative scar formation. The geometric parameters and astigmatism in patients with amblyopia were larger than those in patients without amblyopia.

Abstract
ABSTRACT Clinical registries have been developed for decades in the field of ophthalmology, and they are especially well-suited to the study of keratoplasty practices. A comprehensive donor/recipient registry system can provide insight into donor, recipient, and surgical factors associated with immediate and long-term outcomes and adverse reactions. Furthermore, linkage with demographic databases can elucidate relationships with social determinants of health and potentially shape public policy. The vast sample size and multicenter nature of registries enable researchers to conduct sophisticated multivariate or multilayered analyses. In this review, we aim to emphasize the importance of registry data for keratoplasty practice and 1) summarize the structure of current keratoplasty registries; 2) examine the features and scientific contributions of the registries from Australia, the United Kingdom, Singapore, the Netherlands, Sweden, Eye Bank Association of America, and European Cornea and Cell Transplant registries; 3) compare registry-based studies with large single-site clinical studies; 4) compare registry-based studies with randomized control studies; and 5) make recommendations for future development of keratoplasty registries. Keratoplasty registries have increased our knowledge of corneal transplant practices and their outcomes. Future keratoplasty registry-based studies may be further strengthened by record linkage, data sharing, and international collaboration.

Abstract
Managing pediatric corneal disorders is challenging as the prognosis of pediatric keratoplasty depends on several factors. Advancements in the genetic basis of congenital corneal diseases and investigations in congenital corneal conditions provide a better understanding of pediatric corneal conditions. Surgeons performing keratoplasty in children now have a choice of various techniques. Evolving surgical techniques of anterior lamellar and endothelial keratoplasties has expanded the management interventions in these pediatric corneal morbidity conditions; however, considerable concerns still exist in association with corneal transplantation in infants and children. Outcomes in pediatric keratoplasty depend upon the preoperative indications, the timing of surgical intervention, intraoperative and postoperative factors including the patient/care givers' compliance. Factors such as low scleral rigidity, higher rate of graft failure, need for frequent examinations under anesthesia, and difficulty in optimal visual acuity assessment still remain a considerable challenge in pediatric scenarios. In children, deprivation amblyopia as a result of the corneal opacification can adversely affect visual development, causing dense amblyopia. Outcomes to surgical interventions for management of corneal opacification in children is further compromised by the pre-existing amblyopia apart from the concerns of refractive outcome of the graft. Graft rejection, graft infection, amblyopia, and glaucoma continue to be serious concerns. In recent years both anterior and posterior lamellar keratoplasty techniques are being increasingly performed in pediatric eyes, which offer advantages in the form of lower risk of graft rejection. The timing of surgery, careful case selection, cautious intraoperative approach, and optimal postoperative management can improve the anatomical and functional outcome in difficult cases.

Abstract
PURPOSE To evaluate the outcomes of various lamellar keratoplasty techniques performed at our Institution in children aged 14 years or younger over the last decade. METHODS This single-centre study reviewed 72 eyes that underwent lamellar keratoplasty for various indications. Deep anterior lamellar keratoplasty (DALK) was performed in 19 eyes, mushroom penetrating keratoplasty (PK) in 27 eyes and Descemet stripping automated endothelial keratoplasty (DSAEK) in 25 eyes. The main outcome measures included best spectacle-corrected visual acuity (BSCVA), complications and rate of graft failure which was defined as any graft requiring repeat transplantation. RESULTS Best spectacle-corrected visual acuity (BSCVA) significantly improved after DALK, mushroom PK and DSAEK (all p < 0.05), with 50%, 60% and 56% of eyes reaching ≥20/40, respectively. Stromal rejection was observed in 1 eye (5.3%) after DALK, whilst endothelial rejection occurred in 1 eye after mushroom PK (3.7%) and 1 eye after DSAEK (4.0%). Overall survival was 100% after DALK (mean follow-up: 23.0 months), 92.8% after mushroom PK (mean follow-up: 42.3 months) and 96.0% after DSAEK (mean follow-up: 33.6 months). CONCLUSION Deep anterior lamellar keratoplasty (DALK), mushroom PK and DSAEK offer good visual outcomes for children with corneal pathology, with low rates of immunological rejection and graft failure.

Abstract
To present the natural course of keratoconus (KC) and compare pediatric and adult patients. Design A retrospective cohort study. Setting Hospital-based. Patient Population In total, 152 patients (288 eyes) diagnosed with KC at Chang Gung Memorial Hospital, Taiwan, were included. Previously managed patients and those with missing optical data were excluded. Observation Procedures Patients were divided into pediatric (≤ 18 years) and adult (> 18 years) groups. Demographics, clinical data, and optical variables were collected, including corrected distance visual acuity (CDVA), refractive error, and keratometric readings (K). Main Outcome Measure Optical variables at the final follow-up before aggressive treatment. Results In total, 20 pediatric (37 eyes) and 132 adults (251 eyes) patients were eligible for this study. The mean follow-up time was 2.98 years. Male predominance was observed in both groups. Both groups had similar clinical characteristics and optical variables at the initial diagnosis. Pediatric patients progressed significantly more rapidly in refractive errors, including spheres and cylinders, spherical equivalence, steep K, and flat K during the follow-up. However, significant change between the two study groups was only seen in sphere refractive error spherical equivalence. Conclusion Pediatric patients had more rapidly progressive KC than adult patients, so early detection and frequent follow-up for prompt interventions are necessary for these patients.

Abstract
PURPOSE To report visual and topographic outcomes of pediatric keratoconus with intracorneal ring segments (ICRS) implantation alone or in combination with accelerated corneal cross-linking (A-CXL). METHODS A descriptive, retrospective observational study was performed. Medical records of patients younger than 18 years at Fundación Oftalmológica Nacional in Bogotá, Colombia, were reviewed. Demographic data, follow-up time, preoperative and postoperative uncorrected (UCVA) and best corrected (BCVA) visual acuity, manifest refraction, and tomography were evaluated. SPSS software (version 22.0; SPSS, Inc) was used for analysis. RESULTS Twenty-six eyes of 19 patients with a mean age of 16.5 ± 1.8 years were analyzed, and 16 were boys (84.2%). Median follow-up time was 39.6 months (inter-quartile range [IQR] = 30). Fifteen patients (78.9%) had a history of allergic conjunctivitis. Sixteen eyes (61.5%) received ICRS implantation with A-CXL and 10 eyes (38.4%) received ICRS implantation only. Global results (including ICRS implantation with A-CXL and ICRS implantation only) were: (1) median UCVA of 0.90 logarithm of the minimum angle of resolution (logMAR) (IQR = 0.85) preoperatively improved to 0.54 logMAR (IQR = 0.70) postoperatively; (2) median BCVA of 0.43 logMAR (IQR = 0.39) preoperatively improved to 0.30 logMAR (IQR = 0.26) postoperatively; and (3) median spherical equivalent of -5.37 diopters (D) (IQR = -5.28) preoperatively improved to -4.12 D (IQR = -3.57) postoperatively. There was a reduction in half of the sphere and cylinder. The median maximum keratometry was 54.40 D (IQR = 7.4) preoperatively and 49.80 D (IQR = 5.3) postoperatively. The median asphericity was -1.18 (IQR = 0.70) preoperatively and changed to -0.75 (IQR = 0.68) postoperatively. No patient presented with complications before or after surgery. CONCLUSIONS ICRS implantation only or in combination with A-CXL induced visual and topographic improvement in patients with keratoconus, which was maintained throughout the follow-up time. It seems to be a safe procedure to delay or avoid corneal transplantation in the pediatric population. [J Pediatr Ophthalmol Strabismus. 2022;59(2):118-127.].

Abstract
BACKGROUND Congenital corneal opacity (CCO) is a rare disorder. Penetrating keratoplasty (PK) is the main surgical option for CCO, but many factors affect graft survival. Therefore, this study aimed to perform a virological examination of CCO specimens after PK to explore the relationship between virological factors and graft survival after PK. METHODS This prospective study included consecutive patients (<6 months of age) diagnosed with CCO and treated with PK at Beijing Tongren Hospital from August 2017 to January 2018. Next-generation sequencing was used to detect viral DNA in the CCO specimens. The survival of the primary graft was analysed using the Kaplan-Meier method. RESULTS Overall, 24 eyes of 24 infants were treated with PK during the study period. The mean age at surgery was 4.8±1.1 months. Epstein-Barr virus DNA was detected in two specimens, varicella-zoster virus DNA in one specimen, herpes simplex virus DNA in three specimens and cytomegalovirus DNA in one specimen. In the virus-positive group, only one (14.3%) graft remained clear during follow-up. In contrast, in the virus-negative group (n=17), 13 (76.5%) grafts were still clear at the last follow-up. The mean survival of the grafts in the virus-positive group was significantly shorter than in the virus-negative group (11.0±9.8 months vs 27.1±7.7, p<0.001). CONCLUSION The presence of viral DNA in CCO specimens might be associated with poor graft survival after PK.

Abstract
BACKGROUND Recently, endothelial keratoplasty (EK) has been increasingly considered the first intervention in pediatrics with isolated corneal endothelial dysfunction. This systematic review aims to investigate the current evidence about the advantages, disadvantages, technical challenges, and clinical outcomes of EK in the pediatric group. METHOD All the English literature relevant to pediatric EK was searched in PubMed, Embase, Scopus, and Cochrane databases with appropriate keywords. Relevant data were pooled to conduct an individual participant data meta-analysis. RESULTS Of 1646 articles found initially, 35 articles were finally eligible to be included in our study. A total of 154 eyes of 107 patients underwent Descemet's stripping automated endothelial keratoplasty (DSAEK). Congenital hereditary endothelial dystrophy (CHED) was the most reported indication for pediatric DSAEK (108 eyes). Descemet's membrane endothelial keratoplasty (DMEK) was performed in 2 eyes of 2 cases, one with PPCD and another one in a patient with Kearns-Sayre syndrome. Owing to some specific anatomical and physiological pediatric characteristics, some modifications in a standard procedure were suggested. The average follow-up period was 23.80 ± 20.18 months (3 months to 8.5 years). Seventy-six eyes who had a mean best-corrected visual acuity (BCVA) of 1.36 ± 0.70 (0.49 to 3) logMAR preoperatively found mean BCVA of 0.51 ± 0.33 (0.04 to 2) logMAR postoperatively. Graft dislocation was the most reported complication (26 eyes). The rate of other complications was low. Endothelial cell loss was reported from 8.3 to 63.7% after pediatric EK with follow-up duration from 3 months to 8.3 years. CONCLUSION EK procedures, despite some technical challenges, are feasible surgical techniques with acceptable visual and anatomical outcomes in the management of pediatrics with corneal endothelial dysfunction and minimal stromal involvement.

Abstract
PURPOSE To examine pretransplant findings and outcomes of corneal transplants for keratoconus in children. DESIGN Retrospective cohort (national registry) study. METHODS Data on all patients aged 16 or younger (n = 170) who had a first transplant for keratoconus between 2003 and 2018 in all corneal transplant centers in the UK were compared to adult patients aged 17 and older (n = 7,191). The influence of demographic variables, pretransplant corneal findings, and transplant type on 2-year visual, rejection-free, and transplant survival outcomes was examined. RESULTS Children had poorer pretransplant visual acuity and higher rates of corneal vascularization and ocular surface disease than adults. However, 2-year post-transplant corrected visual acuity reached 20/20 or better in 35% of children compared to 28% of adults (P = .1). Transplant rejection and failure rates were 11% (P = .79) and 3% (P = .31), respectively, for children, which were comparable to rates for adults. Endothelial rejection was reported following penetrating keratoplasty (PK) in 13% of children (10% in adults). Irreversible rejection was not recorded for any transplant in a child. Despite a lack of difference in transplant outcomes, there was a significant age effect in the Cox regression model for transplant rejection, such that for every 5-year increase in age there was a 6% reduction in the hazard of rejection. Transplant survival following anterior lamellar keratoplasty and PK in children was similar. CONCLUSIONS Young keratoconus patients have excellent transplant outcomes and visual results comparable to adults. Overall, the hazard of rejection was found to decrease with advancing age. However, in this large cohort of young patients with keratoconus and poor vision, there is no evidence of outcome advantage in delaying transplant until adult years.

Penetrating Keratoplasty Versus Deep Anterior Lamellar Keratoplasty in Children and Adolescents With Keratoconus. Am J Ophthalmol 2021; 226:13-21. [PMID: 33529592 DOI: 10.1016/j.ajo.2021.01.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 01/18/2021] [Accepted: 01/19/2021] [Indexed: 12/01/2022]
Abstract
PURPOSE To compare the outcomes of penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) for pediatric keratoconus. DESIGN Retrospective comparative interventional case series. METHODS This study included consecutive pediatric keratoconus cases (≤18 years of age) who received PK (n=45) or DALK (n=54) in 2 different time periods. Postoperative best spectacle-corrected visual acuity (BSCVA), refraction, and complications were compared between the study groups. RESULTS The mean follow-up was 83.3±46.1 and 63.3±45.6 months in the PK and DALK groups, respectively (P = .10). Postoperatively, BSCVA was 0.20±0.19 logMAR in the PK group and 0.26±0.19 logMAR in the DALK group (P = .11), with a BSCVA of ≥20/40 in 91.1% and 83.3% of eyes, respectively (P = .25). Two groups were comparable regarding postoperative refractive outcomes. Graft epitheliopathy and suture-associated complications were more commonly encountered after DALK, which was attributable to the effect of low-quality grafts on the clinical outcomes of DALK. Ten PK eyes (22.2%) and 9 DALK eyes (16.7%) experienced at least 1 episode of graft rejection within 5 years of corneal transplantation (P = .49). Rejection was reversible in 93.1% and 100% of episodes in the PK and DALK groups, respectively (P = .63). At the postoperative year 5, 95.6% of grafts in the PK group and 98.2% in the DALK group remained clear (P = .45). CONCLUSION No significant difference was observed in the outcomes between PK and DALK in pediatric keratoconus. Low-quality donor tissues in DALK increased the incidence of graft epithelial problems and suture-related complications as compared to PK.

Abstract
PURPOSE To investigate the causes of graft failure and risk factors associated with total graft opacity after primary penetrating keratoplasty (PK) in children with Peters anomaly (PA). METHODS In this retrospective study, patients with PA (younger than 5 years) who received primary PK in Beijing Tongren Hospital were reviewed. The follow-up period was a minimum of 6 months. A modified PA classification system was used, and all failed grafts were categorized into partial and total opacity groups. Patient demographics, PA classification, operation details, degree of graft opacity, and causes of graft failure were recorded. RESULTS Of the 165 eyes, 54 eyes (32.7%) demonstrated graft failure along with various degrees of graft opacity. Approximately half of the grafts applied failed within 6 months postoperatively. The partial and total opacity groups did not demonstrate any significant differences regarding diagnosis distribution. Irreversible immune rejection accounted for 61.1% of all graft failures; furthermore, it had a significantly higher proportion in the partial opacity group than in the total opacity group (71.0% and 47.8%, respectively; P = 0.058). The degree of graft opacity was significantly associated with patient age at surgery (P = 0.002), preoperative corneal vascularization (P = 0.009), and iris defects (P = 0.001). However, administration of intensive topical corticosteroids could reduce the risk of total opacity in the rejected grafts. CONCLUSIONS Irreversible immune rejection is the most common cause of graft failure after primary PK in pediatric patients with PA. The degree of graft opacity is closely related to patient age at surgery, preoperative corneal vascularization, and iris defects.

Abstract
PURPOSE To determine the prevalence of survival of corneal grafts and visual outcomes of primary penetrating keratoplasty (PK) in infants with Peters anomaly (PA) in Beijing, China. METHODS Twenty-nine patients (37 eyes) with PA who underwent PK before the age of 1 year were included. Optical correction for all eyes and occlusion therapy of amblyopia for a unilateral opacity were performed 2 weeks after suture removal. All infants underwent assessment of visual acuity after surgery using Teller Acuity Cards. Survival probabilities were estimated using the Kaplan-Meier method and log-rank test. Visual outcomes and prognosis factors were analyzed using the χ2 test. RESULTS The mean age of 29 infants undergoing primary PK was 5.7 ± 2.3 months. The mean follow-up duration was 18.0 ± 3.0 months. Twenty-seven (73.0%) of 37 grafts retained full clarity at final follow-up. Visual acuity above ambulatory was achieved in 67.6% (25/37) and >20/260 was achieved in 48.6% (18/37) of cases. Of all surgical indications, vascularized PA I (50.0%, 6/12) and PA II (18.2%, 2/11) showed a lower proportion achieving visual acuity >20/260 than nonvascularized PA I (71.4%, 10/14) (P = 0.030 < 0.05). There was no significant difference in the prevalence of graft survival and vision outcome between infants younger than 6 months and older than >6 months. CONCLUSIONS For infants with PA who underwent PK, the prevalence of graft survival and visual acuity were related mainly to the indication. The main risk factors were corneal vascularization and an abnormal lens.

Abstract
Keratoconus is an ectatic corneal disease characterized by progressive stromal thinning, irregular astigmatism, and defective vision. It can be unilateral or bilateral with asymmetric presentation. It starts at puberty and either progresses rapidly to an advanced stage of the disease or stops in case of delayed onset and slow progression. Pediatric keratoconus is more aggressive than in adults and the management protocols differ because of various rationales such as accelerated progression, advanced stage of disease at the time of diagnosis and co-morbidities. It poses a burden to the society as it affects the quality of life, social, and educational development in children. Hence early diagnosis, recognition of progression, and timely intervention with collagen crosslinking is imperative to arrest the worsening. Association with systemic syndromes and ocular comorbidities can be of concern in pediatric keratoconus. Severe ocular allergy when associated hastens progress and complicates timely intervention of crosslinking treatment and compliance to contact lens wear. Keratoplasty in pediatric keratoconus has good outcomes but can encounter frequent suture-related concerns. This article discusses the epidemiology, etiopathogenesis, clinical challenges, and current perspectives of management of pediatric keratoconus.

Abstract
PURPOSE To present long-term clinical and visual outcomes of patients with Peters anomaly. METHODS The charts of all patients diagnosed with Peters anomaly from January 2000 to December 2012 were reviewed retrospectively. Peters anomaly was classified as type I (with no lens involvement) or type II (presence of keratolenticular adhesions or cataract), with further severity grading to mild, moderate, and severe disease depending on corneal opacity location and size. Mild cases were observed. Moderate cases were managed with pupillary dilation either pharmacologically or surgically. Penetrating keratoplasty (PKP) was reserved for more severe opacity. The main outcome measures were final best spectacle-corrected visual acuity (BSCVA), incidence of glaucoma, graft survival, and nystagmus rates. RESULTS Sixty eyes of 40 patients were included in the study. The median age of patients at presentation was 0.5 ± 20.7 months (range, 0.0-111.0 months), with a mean follow-up time of 75.8 ± 52.9 months (range, 12.1-225.3 months). Overall, final best spectacle-corrected visual acuity ranged from 0.1 logMAR to no light perception with 33 eyes (55.9%) achieving vision of 1.0 logMAR or better. Clear grafts at the last follow-up were obtained in 67.6% (25/37) of transplanted eyes, 76.0% (19/25) in Peters type I, and 50.0% (6/12) in Peters type II (P = 0.11). The probability of a clear graft at 10 years was 74.2% and 38.9% for type I and type II, respectively. Glaucoma was diagnosed in 33.3% eyes, 90.0% of which occurred after PKP. Nystagmus was highly associated with PKP intervention, occurring in 81.1% (30/37) of eyes undergoing PKP compared with 34.8% (8/23) of eyes with no PKP (P = 0.0003). CONCLUSIONS Visual rehabilitation in Peters anomaly remains a challenge, but outcomes can be optimized using a comprehensive clinical management algorithm according to disease severity.

Abstract
The aim of this study was to investigate the histopathological manifestations of congenital corneal staphyloma accompanied by anterior segment dysgenesis and evaluate the prognosis after penetrating keratoplasty with an ultralarge button graft.We retrospectively studied 8 pediatric patients with large congenital corneal staphylomas in the Department of Ophthalmology of Peking University Third Hospital, China, between September 2014 and December 2018. All patients underwent penetrating keratoplasty with ultralarge button grafts, as well as additional operations according to the abnormality of each eye. Pathological investigations of all samples obtained during penetrating keratoplasty were performed with hematoxylin and eosin staining.The main clinical characteristic of congenital corneal staphyloma was an extremely opaque and ectatic cornea. Histopathological examination showed abnormal corneal epithelia and stroma and an absence of Bowman membrane, Descemet membrane, and the endothelium. Different severities of anterior segment dysgenesis, presenting as various histopathological manifestations, were observed in all cases. Several postoperative complications occurred after penetrating keratoplasty in some of the patients; however, the complications were discovered and treated accordingly in a timely manner. Six patients achieved good visual outcomes and a satisfactory cosmetic appearance after penetrating keratoplasty. One patient eventually lost the transparency of the button because of corneal neovascularization, and 1 patient lost visual function because of retinal detachment.Congenital corneal staphyloma combined with anterior segment dysgenesis can exhibit various manifestations on histopathological examination. Penetrating keratoplasty with an ultralarge button graft seems to be a suitable treatment for congenital corneal staphyloma to obtain good functional and aesthetic prognoses.

Abstract
PURPOSE To describe the outcomes of Descemet membrane endothelial keratoplasty (DMEK) performed in amblyopic aged (younger than 8 years) children. METHODS This is a single-center retrospective study, including 11 eyes (7 congenital hereditary endothelial dystrophy and 4 congenital glaucoma) of 6 children in amblyopic age undergoing DMEK by a single surgeon (N.C.P.) at Sorocaba Eye Hospital from December 2015 to November 2017. Best spectacle-corrected visual acuity, biomicroscopy, pachymetry, endothelial cell density, and complications were evaluated. RESULTS No intraoperative complications occurred. Graft detachment occurred in 1 eye (9.1%) and was successfully managed with rebubbling. No primary graft failure or pupillary block was observed. All pachymetric measurements improved, and the corneal edema clinically resolved in all eyes within 2 weeks after the procedure. At the last follow-up (mean 30 months), best spectacle-corrected visual acuity was ≥20/40 in 7 (77.8%) of 9 eyes from patients cooperative enough to assess vision. All children began visual stimulation therapy and amblyopic treatment within 1 month of surgery, and all grafts remained clear until the last follow-up. The mean preoperative donor endothelial cell density was 2588 ± 236 cells/mm, which decreased to 1726 ± 292 cells/mm 2 years after surgery, yielding a 33% reduction (P < 0.001). No immunologic graft reaction, secondary graft failure, or cataracts were observed during the follow-up period. CONCLUSIONS In this series, DMEK was performed to successfully treat endothelial dysfunction in children. However, the procedure is more challenging, and more studies with more patients and longer follow-up are needed to confirm the superiority of DMEK in treating endothelial dysfunction in children.

Abstract
Sclerocornea is a rare congenital anomaly with clouding of the peripheral cornea that possibly extends up to the center of the cornea. Characteristically, a clear distinction (limbus) between sclera and cornea is lacking. Early surgical treatment is essential for preventing amblyopia, but penetrating keratoplasty in children carries a relatively high risk of complications. Especially for sclerocornea, penetrating keratoplasty has generally been reported to have a poor surgical outcome and a high risk of complications, including corneoscleral adhesions. Here, we report the 4-year follow-up on a child with sclerocornea, who was successfully operated on at the age of 3 months and had a favorable outcome. Our findings suggest that in some cases, penetrating keratoplasty may be an option to treat sclerocornea in young children.

Abstract
PURPOSE To determine the effect of age at penetrating keratoplasty (PKP) on graft survival and visual outcome in children with corneal opacities transplanted during infancy. METHODS In this two-center retrospective consecutive cohort study, the medical records of infants who underwent unilateral or bilateral PKP during the first year of life between 2004 and 2011 were reviewed retrospectively. PKP was categorized as early (age 0-90 days) or late (age 91-365 days). Main outcome measures were graft survival and vision (classified as poor, fair, or good, considering both testing method and age norms). RESULTS A total of 62 eyes of 52 infants were included: 19 eyes underwent early PKP; 43 eyes, late PKP. Of the 62 eyes, 61 had central congenital corneal opacities; 1 was acquired. Median follow-up was 38.1 months (range, 12.2-150.5 months). Kaplan-Meier graft survival estimates were 0.92 at 1 year (95% CI, 0.81-0.96) and 0.61 at 5 years (0.44-0.74). Graft survival (early PKP, 73.7%; late PKP, 65.1% [P = 0.57]) did not differ between groups. Of the 55 eyes with recorded visual acuities, no significant difference existed in proportion with ambulatory or better vision at latest follow-up between early and late PKP (42.1% vs 55.6%; P = 0.61). CONCLUSIONS Visual outcomes were better for PKP performed during infancy compared to results of prior reports of late PKP; however, clearing of congenital opacities in the first 3 months of life did not improve visual outcomes compared to later PKP. One-half of grafts survived >5 years. Early PKP did not worsen graft survival, but PKP may be technically easier to perform later in infancy.

Abstract
PURPOSE Interventional study to evaluate the etiology, visual outcome and survival of corneal transplantation in children and to identify the risk factors associated with graft failure. DESIGN Retrospective, interventional consecutive case series. METHODS Medical records of every child 7 years of age or younger who underwent primary penetrating keratoplasty at Department of Ophthalmology, Federal University of São Paulo were reviewed. The parameters evaluated were indications for keratoplasty, graft survival, and postoperative visual acuity (VA) improvement. Children underwent ophthalmologic examination before and after corneal graft, including VA, assessed by the preferential looking test and visual evoked potential. The analysis of transplant survival was performed using the Kaplan-Meier method. RESULTS Fifty-six penetrating transplants were performed in 51 eyes of 43 children. The patients were divided into 2 groups: congenital (72.5%) and acquired (17.5%) corneal opacity. The main indication was congenital glaucoma (29.4%). The overall Kaplan-Meier graft survival rates were 64.7% in the postoperative average follow-up period of 24 months. There was no significant difference in graft survival between the congenital and acquired groups (Mantel-Cox P = .1031). There was significant improvement in VA in both groups (P = .0022 for congenital and P < .0001 for acquired). Rejection and diagnosis of congenital glaucoma were risk factors for graft failure. CONCLUSIONS Congenital glaucoma was the main indication for corneal transplantation and despite the difficulties, prolonged survival and improved VA can be achieved in pediatric transplant. Complications such as rejection and early glaucoma were significantly associated with graft failure.

Abstract
A 3-month-old baby presented with a whitish lesion over the right cornea since birth. Due to the clinical and ultrasonic characteristics of the lesion, a manual anterior lamellar keratoplasty was performed. Histopathological examination showed it to be a simple grade II epibulbar choristoma. Although dermoid tumours are usually considered as benign, some of them, depending on their location, can seriously affect the vision of a paediatric patient. Due to the high probability of amblyopia in these cases, a surgical procedure is mandatory. Anterior lamellar keratoplasty is recommended when the visual axis is compromised without intraocular implications.

Exposure, entropion, and bilateral corneal ulceration in a newborn as a manifestation of chromosome 22 q11.2 duplication syndrome. Am J Ophthalmol Case Rep 2019; 13:16-19. [PMID: 30505980 PMCID: PMC6247406 DOI: 10.1016/j.ajoc.2018.11.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 10/08/2018] [Accepted: 11/02/2018] [Indexed: 01/24/2023] Open
Abstract
Purpose Chromosome 22q11.2 micro-duplication syndrome (MDS), is a rare autosomal dominant condition, with a highly variable phenotype that ranges from unremarkable and asymptomatic, to fatal due to cardiovascular defects. Hypertelorism, downslanting palpebral fissures, superior displacement of the eyebrows, and ptosis are the most commonly reported ocular manifestations. Here, we report a newborn with bilateral exposure, entropion, and corneal ulceration related to 22q11.2 MDS. Observation A newborn girl presented with bilateral upper eyelid entropion, bilateral lower eyelid ectropion, and lagophthalmos. She subsequently developed bilateral corneal ulcers. Topical antibacterial drops, bandage contact lenses, medroxyprogesterone 1%, and fluorometholone 0.1%, together with partial tarsorrhaphy and correction of eyelid malposition, were used to treat the ulcers and address the underlying issues of exposure and entropion. Genetic testing revealed chromosome 22q11.2.MDS; further evaluation revealed systemic manifestations of this syndrome. The ocular surface healed well with gradual improvement of corneal opacification as well as bilateral partial tarsorrhaphy. Conclusion and importance This report is the first that describes a newborn with 22q11.2 MDS presenting with sight-threatening corneal ulceration. Entropion, ectropion, and lagophthalmos were identified and treated, allowing for healing of the corneal surface. Genetic testing revealed a syndrome not known to be associated with eyelid abnormalities and corneal ulceration, but with other important systemic and ocular implications. Bilateral partial tarsorrhaphy should not be excluded as a treatment option for infants who fail more conservative measures for the treatment of exposure.

Cureus 2018; 10:e3744. [PMID: 30800554 PMCID: PMC6384040 DOI: 10.7759/cureus.3744] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Accepted: 12/17/2018] [Indexed: 11/25/2022] Open
Abstract
Purpose To describe the demographics, indications, clinical outcomes and survival rate of penetrating keratoplasty in Malaysian children living in a suburban area, and discuss the literature on paediatric penetrating keratoplasty. Methodology A retrospective review of medical records was performed on children younger than 17 years of age who had undergone penetrating keratoplasty in Hospital Universiti Sains Malaysia from January 2008 to December 2017. We recorded demographic data, presenting visual acuity, indications, final visual acuity, and graft survival at 12 months into the postoperative period. Results Sixteen eyes of 14 children had penetrating keratoplasty. Mean age was 7.8 ± 5.9 years. Both genders were equally affected. The main indications were infective keratitis (56.25%), congenital corneal opacity (18.75%) and trauma (12.50%). There were 62.50% of patients who had a preoperative visual acuity worse than 6/60. Fifty percent had other combined procedures during the surgery, including lens aspiration, peripheral iridectomy, pupilloplasty and glaucoma tube implant. Best corrected visual acuity of 6/12 or better was achieved in 18.75% of patients. A hazy graft was noted in 68.75% of patients, and was attributed to graft rejection, glaucoma and graft failure. There was a statistically significant association between the presence of vascularized cornea, intraocular inflammation and combined surgery with survival rate of the graft at one-year postoperative period (p < 0.05). Conclusions Infective keratitis is the main indication for penetrating keratoplasty in our pediatric patients. Good visual outcome was documented in a small percentage of the patients. Amblyopia and hazy graft were the main barriers to success in this group of patients. Vascularized cornea, inflammation and combined surgery had significantly affected the survival rate of the grafts in our series.

Abstract
PURPOSE To describe the epidemiology and prevalence, rates of progression, difference between adult and pediatric populations, and therapeutic approaches to pediatric keratoconus from documented literature. METHODS A literature search was done on PubMed using key words including pediatric keratoconus, children with keratoconus, adult keratoconus, penetrating keratoplasty, corneal cross-linking and intracorneal ring segments. The literature was reviewed and reported to explore the key epidemiological differences between the pediatric and adult population with regards to presentation and treatment options. RESULTS Pediatric keratoconus is more aggressive than adult keratoconus, which has been explained by structural differences in the cornea between both populations. High rates of progression were documented in pediatric populations. While corneal collagen cross-linking, intracorneal ring segments and penetrating keratoplasties have been used as therapies in the pediatric population, the literature overwhelmingly shows higher rates of failure and progression despite these measures as compared to adults. CONCLUSION Pediatric keratoconus is more aggressive than adult keratoconus, and current therapies used in adults may not be sufficient for the pediatric population.

Abstract
PURPOSE To facilitate development of standardized guidelines for management of pediatric patients undergoing keratoplasty, particularly the youngest cohort, through a comprehensive survey assessing recent trends in practice patterns of corneal specialists and pediatric ophthalmologists. METHODS A cross-sectional, observational study of current practices pertaining to pediatric keratoplasty was performed by designing a 20-question survey focused on preoperative indications, surgical techniques, and postoperative management. This survey was sent electronically to corneal specialists and pediatric ophthalmologists. Results were compared with the findings of previous studies regarding pediatric keratoplasty. RESULTS Of the 80 ophthalmologists who responded, 51.3% currently perform pediatric keratoplasty; only 20% have performed >50 cases. The majority (73.8%) completed solely corneal fellowships; all perform penetrating keratoplasty, 35.2% also perform endothelial keratoplasty, and 37% also perform lamellar keratoplasty. Peters anomaly was the most common indication for transplantation (34.3%). The majority believe that 1 to 3 months is the optimal age range to perform keratoplasty for both monocular and binocular congenital corneal opacities, although 13% stated that they would never perform keratoplasty in a patient with a monocular opacity. All surgeons report modifying their intraoperative techniques for pediatric patients, but specific practices and postoperative management protocols vary. There is a consensus regarding the importance of amblyopia therapy in these patients. CONCLUSIONS Our results were consistent with the published literature regarding the indication and types of surgery performed. Variability among surgical techniques and postoperative management protocols highlights the necessity of creating standardized guidelines to optimize management of pediatric patients undergoing keratoplasty. Collaborative efforts between corneal and pediatric specialists are crucial for defining visual rehabilitation protocols to enhance visual outcomes.

Abstract
PURPOSE To evaluate efficacy of combined vitrectomy with posteriorly placed glaucoma drainage device (GDD) in lowering intraocular pressure (IOP) in children. METHODS The medical records of children who underwent vitrectomy with posteriorly placed GDD were reviewed retrospectively. Patients with a minimum of 6 months' follow-up were included. The first eye operated on for each patient was analyzed. Success was defined as IOP of 5-20 mm Hg and no additional IOP-lowering surgery or visually devastating complications. RESULTS A total of 20 patients were included, with the following etiologies: primary infantile-onset glaucoma, 5 (25%); traumatic glaucoma, 3 (15%); Peters anomaly, 3 (15%); microphthalmia, 5 (25%); glaucoma following cataract surgery, 2 (10%); microspherophakia, 1 (5%); and retinopathy of prematurity, 1 (5%). Eyes with corneal opacification (8 [40%]) underwent endoscopic vitrectomy (5 [25%]), concurrent penetrating keratoplasty (3 [15%]) and/or keratoprosthesis surgery (1 [5%]). Mean follow-up was 1.9 ± 1.1 years (range, 6.5-49.2 months). Vision remained stable or improved in 17 eyes (85%). Mean IOP decreased from 27.2 ± 10.1 mm Hg to 14.5 ± 6.8 mm Hg (P < 0.0001) at last follow-up or at failure. Kaplan-Meier curves showed 12- and 24-month rate of IOP control of 69% and 62%, respectively. The number of glaucoma medications decreased from a mean of 2.3 ± 1.4 to 1.3 ± 1.2 (P < 0.015) at last follow-up or at failure. Overall success rate was 65%. Complications included hypotony (3 [15%]), vitreous hemorrhage (1 [5%]), and retinal detachment (1 [5%]). Two eyes (10%) required surgery for hypotony; 4 eyes (20%) underwent additional glaucoma surgery. CONCLUSIONS Combined surgical approach with vitrectomy and posteriorly placed GDD decreased IOP in complex pediatric glaucomas. Further, endoscope-assisted vitrectomy is useful in cases with corneal opacification. Complication rates of this combined procedure appear to be comparable to traditional anterior chamber approach.

Abstract
PURPOSE To review the indications and outcomes of children undergoing primary penetrating keratoplasty and identify prognostic factors for graft survival. DESIGN Retrospective, interventional case series. METHODS Medical records of every child 12 years of age or younger who underwent primary penetrating keratoplasty at Wills Eye Hospital Cornea Service between 2007 and 2015 were reviewed. Survival of the primary graft was analyzed using the Kaplan-Meier survival method. RESULTS Forty-six eyes of 35 children underwent primary keratoplasty during the study period. The mean age at the time of primary keratoplasty was 24.6 ± 39.9 months. The mean follow-up duration was 36.4 ± 28.8 months. Congenital opacity was the most common diagnosis for primary keratoplasty (89.1%). The overall mean graft survival time was 45.2 ± 5.8 months, with a survival rate of 75.7% at 1 year. The 1-year graft survival rate was 51.9% and 90.7% in eyes with and without glaucoma, respectively. Cox proportional hazards regression analysis demonstrated that the presence of glaucoma (P = .014) and concurrent operation during primary keratoplasty (P = .049) were independent prognostic factors for poor graft survival. On the other hand, age of primary keratoplasty (P = .626) and operation before or after primary keratoplasty (P = .800 and P = .104, respectively) were not associated with poorer graft survival. Half of our patients were able to achieve ambulatory vision at the last follow-up. CONCLUSION Although pediatric penetrating keratoplasty is challenging, successful transplantation with good graft survival can be obtained. Better understanding of prognostic factors can possibly improve graft survival in the future.

Abstract
PURPOSE The purpose was to evaluate indications and clinical outcomes in paediatric corneal keratoplasty. METHODS Fifty-four eyes of 43 patients who underwent corneal keratoplasty from the 1st of January 2010 through the 31st of December 2013 at the Bambino Gesù Children's Hospital in Rome, Italy, were retrospectively evaluated. To assess the effect of age on graft failure rate, the recipient age was considered as a dichotomous variable (≤5 or >5 years) and a 2X2 table was developed, using the chi-square test for testing the statistical significance. Furthermore, two separate subgroup analyses were conducted on patients of ≤5 years and those of >5 years, to evaluate the effect of penetrating keratoplasty (PK) or deep anterior lamellar keratoplasty (DALK) on the graft failure rate. The level of statistical significance was set at p < 0.05 RESULTS: Mean recipient age was 8.9 ± 5.7 [SD] years. Mean follow-up time was 22.8 months. Main preoperative diagnoses were keratoconus (37 %) and congenital glaucoma (20 %). Patients ≤5 years showed a higher percentage of graft failure (p = 0.0008). PK and DALK did not show statistically significant differences regarding the graft failure in both subgroups (p = 0.15 for ≤5 years group and p = 0.27 for >5 years group, respectively). However, across groups DALK provided a lower rate of graft failure. CONCLUSIONS Our findings suggest that children older than 5 years show a significantly better graft outcome and that DALK seems to offer greatest benefits in terms of failure risk in paediatric patients.
