Incidence and Risk Factors for Retinal Detachment Following Pediatric Cataract Surgery.

Background: Retinal detachment is a major postsurgical threat in pediatric cataract surgery; however, the effect of axial length remains unclear. This study aimed to assess the relationship between axial length and detachment risk in vulnerable patients. Methods: This retrospective cohort study analyzed 132 eyes of 84 pediatric cataract surgery patients aged <20 years old. Axial length was measured preoperatively, and the incidence of retinal detachment was recorded over a median follow-up of 4 years. Logistic regression analysis was used to examine the axial length-detachment relationship. Results: Twenty eyes had postoperative retinal detachments. The median axial length was longer in the detachment group (23.6 mm) than in the non-detachment group (21.6 mm). Eyes with axial length ≤23.4 mm had 0.55-fold decreased odds of detachment compared to longer eyes. Preexisting myopia and glaucoma confer heightened risk. Approximately half of the patients retained some detachment risk eight years postoperatively. Conclusion: Shorter eyes (axial length ≤23.4 mm) appear to be protected against pediatric retinal detachment after cataract surgery, whereas myopia, glaucoma, and axial elongation > 23.4 mm elevate the postoperative risk. Understanding these anatomical risk profiles requires surgical planning and follow-up care of children undergoing lensectomy.

This study investigated the protective role of a shorter axial length in preventing retinal detachment after pediatric cataract surgery. This highlights the correlation between smaller eye sizes and reduced detachment risk, emphasizing the need for careful consideration of anatomical factors in surgical planning and patient monitoring, particularly for patients with preexisting myopia or postoperative glaucoma.

Longitudinal evaluation of macular vascular density alterations in unilateral amblyopic children undergoing therapy: An optical coherence tomographic angiography study.

Importance: Understanding the pathophysiology of the macula in amblyopic eyes is an active research area. Objective: To correlate macular retinal vascular density changes with best-corrected visual acuity changes following occlusion therapy for amblyopia in children. Design: A prospective cohort study of children visiting the Pediatric Ophthalmology Division of our institution between January 2020 and January 2022 was conducted. Setting: A specialist eye hospital in Saudi Arabia. Participants: Thirty children with unilateral amblyopia. Exposure: Occlusion therapy for amblyopia.Main Outcome and Measures: Best corrected visual acuity (logMAR) before and at each of the four optical coherence tomographic angiographies was compared in amblyopic and fellow eyes. The effect of pretreatment determinants on the correlation between best-corrected visual acuity and retinal vascular density changes was reviewed. Results: In this cohort of 30 amblyopic and 30 fellow eyes from 30 children (mean age 8.7 ± 1.4 years; male: female 18:12. The best-corrected visual acuity improved from a median of 0.6 (interquartile range 0.5; 1.1) pretreatment to a median of 0.4 (interquartile range 0.2; 0.6) posttreatment in amblyopic eyes, and from a median of 0.1 to 0.05 in the fellow eyes. The total percentage change in retinal vascular density in the amblyopic eye was significantly higher than that in the fellow eye (Z = -1.92, P = 0.05). The change in best-corrected visual acuity in the amblyopic eye after a median of 98 months (interquartile range, 69-126 months) of intervention was significantly correlated with the refraction-adjusted change in retinal vascular density (B = -0.03, 95 % confidence interval -0.04, -0.02, P < 0.001) and was influenced by strabismus (B = -0.46, 95 % confidence interval -0.59, -0.34, P < 0.001), type of amblyopia (B = 0.24, 95 % confidence interval 0.12, 0.36, P < 0.001), duration of occlusion (B = -0.43, 95 % confidence interval -0.65, -0.22, P < 0.001), and occlusion compliance (B = 0.24, 95 % confidence interval 0.11, 0.36, P < 0.001). Conclusions: and Relevance: The RVD in amblyopic eyes in the first six months of therapy was significantly lower than that in fellow eyes, but not in subsequent assessments.

Effect of Trabeculodescemetic Window Perforation in Deep Sclerectomy on Intraocular Pressure in Primary Congenital Glaucoma.

INTRODUCTION: Primary congenital glaucoma causes vision loss if intraocular pressure is uncontrolled. Nonpenetrating deep sclerectomy is effective in treating primary congenital glaucoma. However, the effects of inadvertent trabeculodescemetic window perforation remain unclear. METHODS: This retrospective cohort study included patients with primary congenital glaucoma who underwent nonpenetrating deep sclerectomy between 2014 and 2021. The perforation group had intraoperative trabeculodescemetic window perforations; the non-perforation group did not. The primary outcome was intraocular pressure between the groups over 15 months. The secondary outcomes included surgical success and complications. RESULTS: The study included 74 eyes of 44 patients. The cohort comprised 31 perforated and 43 non-perforated eyes. Both groups showed significant intraocular pressure reduction without significant between-group differences in complete (68 vs. 77%), qualified (19 vs. 9%), or failed (13 vs. 14%) treatments. The median intraocular pressure decreased from 39 to 14 mmHg in the perforation group and 35 to 12 mmHg in the non-perforation group. Of the 74 treated eyes, 68 (92%) showed no complications. CONCLUSIONS: An inadvertent trabeculodescemetic window perforation during nonpenetrating deep sclerectomy for primary congenital glaucoma did not significantly affect intraocular pressure outcomes compared to non-perforated cases over 15 months. Nonpenetrating deep sclerectomy reduced intraocular pressure regardless of intraoperative perforation in patients with primary congenital glaucoma. Perforation of the trabeculodescemetic window was associated with a low incidence of postoperative complications.

Evaluation of Foveal Avascular Zone After Strabismic and Anisometropic Amblyopia Therapy in Saudi Children Using Optic Coherence Tomography Angiography: A Cohort Study.

Purpose: Optical coherence tomography angiography (OCTA) noninvasively images retinal microvasculature. Foveal avascular zone (FAZ) biomarkers can act as indicators of various forms of amblyopia, making them valuable tools for clinicians. The purpose of this study was to assess the effect of amblyopia therapy on the FAZ using OCTA to determine FAZ size in children with untreated amblyopia. Patients and Methods: This two-arm cohort study enrolled 23 children with untreated strabismic or anisometropic amblyopia who underwent OCTA between 2021-2022. Each arm had 23 eyes, with one arm having amblyopic eyes and the other having normal eyes. FAZ area, perimeter, and circularity index were measured before and quarterly during 1 year of occlusion therapy. Differences in avascular zone biomarkers between amblyopic and fellow eyes were compared and linked to demographic and ocular factors. Results: Similar FAZ areas were found in the amblyopic (0.3 mm2) and nonamblyopic eyes (0.28 mm2) (P = 0.83), with no significant change in either group (P = 0.93). Amblyopic eyes showed a larger FAZ perimeter reduction (0.12 mm2) than fellow eyes (0.02 mm2), but the difference was not statistically significant (P = 0.09). The circularity index in amblyopic eyes matched with fellow eyes (0.67 mm2), P = 0.38. Initial visual acuity and strabismus correlated with changes in the follow-up FAZ area. Conclusion: Amblyopia treatment did not significantly alter FAZ area in this cohort. Perimeter variations between amblyopic and fellow eyes require further study. The conclusions were limited by the sample size and lack of randomization.

A Novel Technique Using Paretic Superior Rectus as a Globe Suspender for Monocular Elevation Deficiency.

Surgical innovations in strabismus provide opportunities to improve visual function, eye alignment, and cosmesis in rare pediatric ophthalmological conditions. Monocular elevation deficiency is a rare and multifactorial disease in which the affected eye is equally limited in terms of elevation during adduction and abduction. We aimed to present a novel procedure for the treatment of acquired monocular elevation deficiency using the paretic superior rectus muscle as a globe suspender to resolve hypotropia. We report the case of an eight-year-old girl with left eyelid ptosis and hypotropia two months after draining a left orbital abscess. Left inferior rectus muscle recession was performed at five years, with residual left hypotropia. Ophthalmological examination revealed a best-corrected visual acuity of 20/20 OD and 20/100 OS. Severe left eyelid ptosis and poor levator function were also observed. Extraocular motility showed left hypotropia of 40 prism diopters with the left superior rectus muscle under action (-4) in the adduction and abduction positions. A force duction test negative for restrictions on the inferior rectus muscle was performed intraoperatively. To reduce the risks of the Knapp procedure, the left superior rectus muscle was split into medial and temporal halves. Double-armed sutures were secured in half, and the halves were detached from the sclera. The medial and temporal halves were reattached anteriorly to the medial and lateral rectus insertions, respectively. Eight weeks after surgery, the patient had nine prism diopters of hypotropia in the primary gaze. Ten weeks after surgery, there was no change in visual acuity. In the cover test, the patient exhibited residual left hypotropia of nine prism diopters with a restriction (-4) of elevation in adduction and abduction. The parents were pleased with the satisfactory cosmetic outcomes, and postoperative clinical photographs of the patient showed improved hypotropia and persistent minimal elevation of the left eye during adduction and abduction. Superior rectus muscle splitting and vertical transposition to the medial and lateral rectus could be safer and simpler alternatives to the Knapp procedure and may offer a lower risk of anterior segment ischemia. Further studies are required to confirm these findings.

Ocular Survival Following Intravitreal Melphalan as Adjuvant Treatment for Vitreous Retinoblastoma Seeding.

Purpose: To evaluate the efficacy of intravitreal chemotherapy for vitreous seeding in patients with retinoblastoma (Rb). Design: Retrospective, single-arm cohort study. Methods: This study was conducted at a tertiary eye center. Between 2013 and 2021, 27 patients (27 eyes) with vitreous Rb receiving adjuvant intravitreal melphalan (IVM) as secondary/salvage treatment in one eye were included. Patients who were unable to follow-up or treated elsewhere were excluded. Survival analysis was performed to assess the incidence of enucleation in the melphalan-treated group, as well as in bilateral cases with eyes receiving melphalan and those receiving standard treatment, consisting of chemotherapy, thermotherapy, and enucleation according to the disease stage. Results: The median (interquartile range) follow-up time was 65 months (range, 34-83 months). Seventeen patients (63%) had bilateral disease. Sixteen eyes (59%) were saved. The Kaplan-Meier survival estimates for eyes receiving melphalan were 100% at 1 year (95% confidence interval [CI]:11.2-14.3), 75% (95% CI:14.2-48.9) at 3 years, and 50% at 5 years. Melphalan-treated patients with bilateral disease showed a significantly higher number of saved eyes than the standard treatment group (P=0.002). Tumor recurrence was the primary cause of enucleation, accounting for 36% of the cases. In the vitreous hemorrhage group, the odds of enucleation were 13 times higher (95% CI:1.04-165.28) than in the group without this condition. Conclusion: IVM is an effective treatment option for vitreous seeds. After 3 years of follow-up, the estimated survival rate for saved eyes decreased, and vitreous hemorrhage significantly increased the likelihood of enucleation. Further studies are required to determine the precise effects of IVM.

Outcomes of Non-Penetrating Deep Sclerectomy for Primary Congenital Glaucoma Performed by Experienced versus Trainee Surgeons: A Cohort Study.

Purpose: To compare the outcomes of non-penetrating deep sclerectomy (NPDS) for primary congenital glaucoma (PCG) performed by experienced vs trainee surgeons. Patients and Methods: This retrospective cohort study was conducted in 2022 in Saudi Arabia. Consultants (Gr-1) and trainee pediatric ophthalmologists (Gr-2) performed NPDS on pediatric patients with PCG. Success was defined as an intraocular pressure (IOP) less than 21 mmHg at 6 months after surgery. Complications, glaucoma medications, and additional procedures were also observed in the two groups. Results: Gr-1 and Gr-2 operated on 14 and 39 eyes with PCG, respectively. The absolute success rates were 90.9% (95% confidence interval [CI]: 73.9, 100) in Gr-1 and 96.7% (95% CI: 90.2, 100) in Gr-2 (odds Ratio=1.1; 95% CI: 0.87, 1.3; P=0.54). Survival analysis suggested that the failure rate in the first 6 months after NPDS was not significantly different between the two groups (hazard ratio=1.45; 95% CI: 0.13, 16.0; P=0.767). The complications included hypotony (2 cases), vitreous hemorrhage (1 case), and total flap penetration (1 case). Only one eye in Gr-2 needed glaucoma medication after surgery. There was no significant difference in the success rates of one surgeon before and after training (P=0.43). The age (P=0.59) and sex (P=0.77) of patients, type of surgeon (P=0.94), and preoperative IOP (P=0.59) were not significant predictors of a stable IOP at 6 months after NPDS. Conclusion: At 6 months after NPDS surgery performed by experienced and trainee pediatric ophthalmologists, the outcomes (stabilization of IOP) were similar between the two groups.

Conventional surgery versus botulinum toxin injection for the management of esotropia in children with Down syndrome.

PURPOSE: To compare the success rates of strabismus surgery and botulinum toxin injection (BTX) in treating esotropia in patients with Down syndrome (DS). METHODS: This multicenter retrospective cohort study included all consecutive patients having DS with esotropia between 2014 and 2021 at King Abdullah Specialist Children Hospital, King Abdullah International Medical Research Center, and King Khaled Eye Specialist Hospital, Saudi Arabia. We divided the patients into two groups according to interventions. Success was defined as angle of deviation of <10Δ at final visit. RESULTS: A total of 53 patients were included: 23 in the surgery group and 30 in the BTX group. There were no significant differences between groups with regard to age, sex, diagnosis, spherical equivalent, and preoperative deviation angle. Before the intervention, the median angle of deviation was 30.0Δ (IQR, 30Δ-45Δ) in the surgery group and 37.5Δ (IQR, 28.8Δ-50.0Δ) in the BTX group (P = 0.802). Postoperatively, the median (IQR) deviation angle was 0.0Δ (0.0Δ-16.0Δ) in the surgery group and 22.5Δ (6.75Δ-30.0Δ) in the BTX group (P = 0.006). The success rate in the surgery and BTX groups was 65% and 30%, respectively (P = 0.011). Two patients developed dissociated vertical deviation in the surgery group. One patient presented consecutive exotropia and one inferior oblique overaction in the BTX group. CONCLUSIONS: In this study, conventional surgery showed a higher success rate than BTX in the management of esotropia.

Incidence and outcomes of microbial keratitis after cyclophotocoagulation to treat childhood refractory glaucoma.

PURPOSE: To report the incidence and outcomes of microbial keratitis (MK) following cyclophotocoagulation (CPC) for treatment of refractory childhood glaucoma (CG) at a single center over a period of 6 years. METHODS: In this cohort study, the medical records of children with CG who underwent CPC and subsequently presented with MK from 2014 to 2020 were reviewed retrospectively. Data were collected on age, type of glaucoma, surgeries before MK, CPC parameters, interval between CPC and MK, presenting symptoms of MK, infiltrate location, bacterial isolates, MK treatment, and outcomes. RESULTS: Among the 312 children who underwent CPC during the study period, 37 eyes of 33 children had MK, with an incidence of 1.8% (95% CI, 0.3-3.2). The median interval between CPC and MK was 4 years (IQR, 2.7-7.4). CPC was repeated once in 20 eyes (54%) and twice in 4 (11%). In 20 eyes, there was no pain at MK onset. The primary isolates were Streptococcus pneumoniae (12/27 [22%]) and Staphylococcus epidermis (8/27 [30%]). MK resolved in 17 eyes (46%) after treatment; 8 eyes (22%) underwent evisceration or had phthisis, and keratoplasty failed in 6 eyes (16%). The absence of pain at presentation with MK was negatively associated with resolution (OR = 5.0 [95% CI, 1.1-23.8]; P = 0.04). CONCLUSIONS: The absence of pain at MK onset may be a proxy for neurotrophic keratitis after CPC and is linked to poor response to management.

Bilateral Phakomatosis Cesiomarmorata With Ocular Melanocytosis and Secondary Glaucoma.

Phakomatosis pigmentovascularis (PPV) is a family of rare congenital diseases where vascular malformation coexists with melanocytic, dermal, or ocular lesions. The cesiomarmorata type is even rarer, and most such cases are reported with unilateral occurrence. We present an atypical case of a patient with bilateral phakomatosis cesiomarmorata, bilateral ocular melanocytosis, and bilateral glaucoma. No malformation to resist aqueous drainage was identified. Long-term management of intraocular pressure (IOP) using topical antiglaucoma medication was successful. This case report refines the clinical presentation of phakomatosis cesiomarmorata and may help diagnose and treat future cases.

Heavy eye syndrome in a myopic patient with prior scleral buckle surgery for rhegmatogenous retinal detachment: Differential diagnosis and management.

PURPOSE: To present a challenging case of heavy eye syndrome (HES) in a 56-year-old female who previously underwent scleral buckle surgery in both eyes. OBSERVATIONS: Ophthalmic tests indicated a diagnosis of HES, confirmed using pre and postoperative magnetic resonance imaging (MRI). A silicone band loop myopexy was performed, successfully improving large angle esotropia at primary position and motility. CONCLUSIONS AND IMPORTANCE: MRI is essential to correctly identify HES, allowing a tailored surgical intervention that may lead to better outcomes for patients. Up to our knowledge, this is the first reported case of scleral fixated silicone band loop myopexy for HES in a previously scleral buckled patient.

Treatment Outcome of Occlusion for Unilateral Amblyopia in Saudi Children 6-12 Years Old.

PURPOSE: The purpose of this study was to estimate the rate and review determinants of successful therapy for unilateral amblyopia in children. METHODS: This prospective cohort consisted of Saudi children aged 6-12 who received amblyopia therapy between 2020 and 2022. Best-corrected visual acuity (BCVA) in the amblyopic eye improved to reach the BCVA of the fellow eye at follow-up visits, or BCVA in the amblyopic eye improved and remained stable over three follow-up visits. Demographic and ocular characteristics were associated with the outcome. RESULTS: In 30 children, the median BCVA at presentation and the last follow-up was 0.8 logMAR (interquartile range [IQR]: 0.6; 1.0) and 0.45 logMAR (IQR: 0.3; 0.6), respectively. The success rate of amblyopia therapy was 80% (95% confidence interval: 65.7; 94.3). It was 100%, 76.5%, and 77.8% in eyes with anisometropic, strabismic, and mixed types of amblyopia, respectively. Amblyopia grade (P = 0.177), type of amblyopia (P = 0.96), and spectacles as therapy in the past (P = 0.09) were not significantly associated with the successful out. The duration of follow-up was significantly longer in those with unsuccessful outcomes (P = 0.05). Excellent compliance for occlusion was observed in 62.5% of children with successful outcomes. In 14 (46.7%) children, BCVA was ≤0.3 logMAR BCVA at the last follow-up. Two-line improvement in amblyopic eyes was in 26 (86.7%) children at the last follow-up compared to BCVA at presentation. CONCLUSION: Occlusion therapy complemented using glasses in older children also significantly improved visual recovery in amblyopic eyes.

Factors Affecting the Efficacy of Botulinum Toxin Injection in the Treatment of Infantile and Partially Accommodative Esotropia.

PURPOSE: We aimed to investigate the effect of botulinum toxin (BT) injection on the treatment of infantile and partially accommodative esotropia (PAET). METHODS: This retrospective cohort study included patients who received BT injections for infantile and PAET between January 2015 and December 2018. Treatment was considered successful if orthotropia, consecutive exotropia, or esotropia within 10 prism diopters (PD) was achieved. RESULTS: The overall success rate was 47.4%, with a mean follow-up period of 27.8 months in 403 children. BT treatment was considered successful in 37.1% of cases of infantile esotropia and 53.1% of cases of partially accommodative esotropia. The average deviation angle before starting treatment was 35.5 ± 13.9 PD. Side effects 1 week after BT injections included transient overcorrection (63.8%) and transient ptosis (41.7%). There were no significant differences in the success rates between the different doses of BT (P = 0.69). The angle of deviation at presentation was significantly associated with the success rate of BT injection (failed group, mean: 38.1 ± 15.3 PD vs. success group, mean: 32.6 ± 11.6 PD; P < 0.001). Other factors associated with higher success rates were overcorrection at 1 week and PAET, while multivariate logistic regression analysis showed that a smaller angle of deviation and overcorrection (1 week after injection) were associated with a higher success rate. CONCLUSION: A smaller angle of deviation and transient overcorrection were associated with a higher success rate, and no significant difference was observed in the success rates of different BT doses.

Strabismus Surgery Outcomes and Their Determinants in Patients with Chronic Sixth Nerve Palsy.

PURPOSE: Patients with chronic sixth nerve palsy (CSNP) comprise a heterogeneous population, and the optimal surgical solution remains uncertain. Here, we present the success rate and factors associated with the success of strabismus surgeries for CSNP. METHODS: This was a retrospective cohort study of patients with strabismus due to CSNP operated on between 2015 and 2019 in a tertiary eye hospital in central Saudi Arabia. Surgical success was defined as a horizontal deviation of ≤10 prism diopters (PDs) assessed at least 12 months after surgery. Differences between groups with respect to the primary outcome were assessed. RESULTS: Fifty-five patients were analyzed with a median follow-up of 24 (range 12-48) months. Superior rectus and inferior rectus transposition (34.5%) and medial rectus recession with lateral rectus resection (32.7%) were the main surgeries performed. The overall success rate was 67.3% (95% confidence interval 54.9-79.7). Bilateral CSNP (P = 0.05), a higher preoperative angle of deviation (P = 0.002), or a greater degree of preoperative limitation of abduction (P = 0.012), but not the type of surgery (P = 0.09), were more likely to result in an under-corrected outcome of >10 PD. The preoperative deviation angle showed a trend toward being associated with a poor outcome after surgery (P = 0.06). Six patients with high-angle deviation before surgery required second surgery. CONCLUSION: While the surgical procedure does not impact outcomes, the severity of preoperative horizontal deviation might impact surgical success and the need for reoperation. Patients with severe CSNP should be counseled appropriately about the chances of surgical success and the potential need for further interventions.

Efficacy of Botulinum Toxin Injection in Exotropia Treatment.

PURPOSE: Botulinum toxin (Botox) therapy is a well-known option for strabismus management and is often used in managing esotropia. Exotropia is also a common type of strabismus; however, the effectiveness of Botox in improving exotropia is still ambiguous. In this study, we report our experience in using Botox to manage the various types of exotropia. METHODS: A retrospective cohort study was conducted at King Khaled Eye Specialist Hospital Riyadh, Saudi Arabia. Medical records of patients with exotropia who received Botox from 2014 to March 2020 were reviewed. The main success indicator was a remaining angle of less than 10 prism diopters (PD). RESULTS: A total of 97 cases were reviewed, with 57 (58.8%) males and 40 (41.2%) females. The age ranged from 2 months to 40 years. The most prevalent diagnosis was sensory exotropia. Overall, 28 patients (28.9 %) and 49 patients (50.5%) achieved an angle of deviation within 10 PD and within 20 PD, respectively. Female patients had a better response to Botox than males, with 32.5% of them achieving an angle of deviation within 10 PD and 60% achieving an angle of deviation within 20 PD. We found that the change in the angle of deviation increased as the Botox dose was increased. CONCLUSION: Botox represents a possible safe alternative to surgery in the management of some exotropia types. The success rate differs by type, with basic exotropia scoring the highest. The presence of poor vision and amblyopia leads to a significantly lower success rate.

Virtual Consultation for Red Eye: Accuracy Assessment in a Primary Care Center.

PURPOSE: The purpose of the study was to evaluate the accuracy of teleexamination of red eye by a trained general practitioner (GP) compared to the gold standard (in-office consultation by an ophthalmologist). METHODS: This was a study of diagnostic accuracy. We included consecutive male or female patients aged ≥6 months who presented to a primary care clinic in Riyadh, Saudi Arabia, with red eye. All the patients were initially evaluated by a trained GP using a standardized checklist and consulted virtually with an ophthalmologist. This was followed by an in-office eye examination conducted at a well-equipped ophthalmology clinic by a well-trained ophthalmologist. Data were analyzed using STATA 17.0 (StataCorp LLC, College Station, TX, USA). RESULTS: A total of 54 patients with red eye presented to the primary care clinic during September-November 2021 and were initially examined virtually and then in-office. The mean age of the patients was 39.72 ± 21.70 years (range 5-90 years). Thirty-three patients (61.1%) were males. The most common cause of red eye was conjunctivitis (46.3%) followed by dry eye (31.5%). There was a significant association between viral conjunctivitis and age (P < 0.001), and between dry eye and age (P = 0.002). Tele eye examination accurately identified the etiology of red eye in all 54 patients. CONCLUSION: Telemedicine has the potential to correctly diagnose patients with red eye and can result in a substantial decrease in the number of people visiting the health-care centers.

Bilateral Spontaneous Hyphema in Juvenile Xanthogranuloma: A Case Report.

Juvenile xanthogranuloma (JXG) is an idiopathic granulomatous inflammatory condition that usually affects children. Intraocular involvement, especially bilateral, is rare in JXG. Most patients with ocular lesions are typically infants and usually present with hyphema, iridocyclitis, and secondary glaucoma. We report a case of a 3-month-old baby girl who presented to our emergency department with bilateral hyphema that started 3 weeks ago. She was medically free with no history of any recent trauma or preceding febrile illness. General physical examination showed a quiet baby with multiple hyperpigmented macules over the inner thigh and right upper arm, with one pinkish nodule over the occiput. She also had high intraocular pressures. A detailed ophthalmic assessment was done under general anesthesia. The nodular lesion was excised and sent for histopathological evaluation, which confirmed the diagnosis of JXG. Treatment of JXG cases present a challenge to ophthalmologist due to rebleeding and refractory glaucoma. Our case was admitted multiple times for rebleeding and refractory glaucoma and was treated with full antiglaucoma drops, steroid drops and peribulbar injection of steroid.

Congenital bilateral upper lid eversion.

We report two healthy Saudi newborns with congenital bilateral upper lid eversion evolving with good outcome using conservative treatment. The current literature including epidemiology, clinical characteristics, possible etiologic factors, and treatment was reviewed.

Hiperfunción de oblicuos inferiores en pacientes con esotropia esencial infantil: ¿parálisis de obicluo superior? / Hiperfuntion of superior oblique muscle in patients with infantile essential esotropia: superior oblique palsy?

Establecer la presencia de parálisis congénita de oblicuo superior en pacientes con esotropia esencial infantil basados en los resultados del "test de tracción exagerada". Se seleccionaron 23 pacientes con el diagnóstico de esotropia esencial infantil, se dividieron en 2 grupos: Grupo 1: 10 pacientes con esotropia con hiperfunción de oblicuos inferiores y Grupo 2: 13 pacientes quienes presentan al momento del examen oftalmológico esotropia sin hiperfunción del oblicuo inferior bilateral. Bajo anestesia general y previa cirugía, el mismo oftalmólogo (JC) les practicó el "test de tracción exagerada" descrito por Guytonsin saber a que grupo pertenecía cada paciente. Las probabilidades que el test de tracción del oblicuo superior resulte positiva (parálisis congénita del oblicuo superior) en los pacientes del grupo 1 es de 100 por ciento. La probabilidad de que el test de tracción del oblicuo superior en pacientes del grupo 2 resulte negativa es de 86,66 por ciento. Los pacientes con esotropia infantil e hiperfunción de oblicuo inferior del estudio tienen un test de tracción del oblicuo superior positivo y una hipótesis que pudiera plantearse es si la esotropia surge como un mecanismo sensorial de adaptación ante esta alteración anatómica y no con un evento primario

Trauma infanto juvenil / Trauma children and adolescents

Presentamos una revisión retrospectiva de los traumatismos en los menores de 18 años en el Hospital "Leopoldo Manrique" entre los años de 1981 a 1991, con el objeto de evaluar este problema de salud pública. Durante este lapso, 231 casos fueron operados por el Servicio de Cirugía, con predominio evidente del sexo masculino; 134 pacientes presentaron heridas por arma de fuego. Las lesiones abdominales fueron las más frecuentes (1991 pacientes), aun cuando muchos pacientes presentaron lesiones multisistémicas. Las vísceras huecas, hígado y vasos fueron la estructuras más comunmente lesionadas. La mortalidad de acuerdo al agente agresor fue de 119 por arma de fuego, cuarenta y nueve por accidentes de tránsito, veintiocho con armas blancas y sesenta y nueve por otras causas diferentes
