RESUMO
BACKGROUND: Ocular trauma is one of the leading causes of decreased visual acuity and monocular blindness in the pediatric population. Since its occurrence is potentially preventable, it is essential to understand its demographic characteristics and risk factors to alert and implement prevention and health promotion programs. METHODS: We conducted a retrospective study in which we reviewed 187 clinical records of patients ≤ 15 years old with the diagnosis of severe ocular trauma admitted in 2017 to the Hospital Civil de Guadalajara. We analyzed demographic variables, circumstances of the event, type of treatment, and the evolution of visual acuity and complications. RESULTS: In total, 187 patients and 188 eyes were included; the average age was 6.99 ± 4.1 years. Children of 2 to 5 years of age (41%) were the most affected, and a higher occurrence was observed in males (73%). Open ocular trauma was the most common type of injury (72.7%) caused by sharp objects (45.4%). Most injuries occurred at home (78.1%), without adult supervision (48.1%), and during leisure time (74.9%). Most events were accidental (80.4%), although 12.3% were direct aggression. Surgery was required in 179 patients, in whom corneal injury repair (43.2%) was the most commonly used procedure. Final visual acuity was quantified in 132 eyes, and visual acuity < 20/200 was found in 18.1%. Loss of 4.2% of the eyeballs was recorded. CONCLUSIONS: The highest proportion of cases was identified in male patients ≤5 years old, unsupervised by an adult. Many eye injuries are preventable, so it is necessary to implement socio-educational programs in alliance with pediatric organizations that alert the severity of the problem and promote safe environments.
INTRODUCCIÓN: El trauma ocular es una de las principales causas de disminución de la agudeza visual y de ceguera monocular en la población pediátrica. Su ocurrencia es potencialmente prevenible, por lo que es importante entender sus características demográficas y riesgos para alertar e implementar programas enfocados hacia la prevención y la promoción de la salud. MÉTODOS: Estudio retrospectivo en el que se analizaron 187 expedientes de pacientes ≤ 15 años con diagnóstico de trauma ocular grave ingresados en 2017 al Hospital Civil de Guadalajara. Se analizaron variables demográficas, circunstancias del evento y tipo de tratamiento, así como la evolución de la agudeza visual y las complicaciones. RESULTADOS: Se incluyeron 187 pacientes y 188 ojos; el promedio de edad en el momento del trauma fue de 6.99 ± 4.1 años. Los niños de 2-5 años (41%) fueron los más afectados y se observó una mayor ocurrencia en el sexo masculino (73%). El trauma ocular abierto fue el tipo de lesión más común (72.7%), causado por objetos punzantes (45.4%). La mayoría de las lesiones ocurrieron en casa (78.1%), sin supervisión de un adulto (48.1%) y durante el tiempo libre (74.9%). La mayoría de los sucesos fueron accidentales (80.4%), aunque el 12.3% fue por agresiones directas. Se requirió cirugía en 179 pacientes, en quienes la reparación de lesión corneal (43.2%) fue el procedimiento más utilizado. La agudeza visual final se cuantificó en 132 ojos y se encontró < 20/200 en el 18.1%. Se registró la pérdida del 4.2% de los globos oculares. CONCLUSIONES: La proporción más alta de casos se identificó en pacientes de sexo masculino ≤ 5 años, que se encontraban sin supervisión. Una gran proporción de las lesiones oculares son prevenibles, por lo que es necesario implementar programas educativos sociales en coordinación con organizaciones pediátricas que alerten de la gravedad del problema y promuevan entornos seguros.

PURPOSE: The purpose of this study was to evaluate the clinical efficacy and safety of a novel ophthalmic solution of pazufloxacin on the ocular surface of patients with bacterial conjunctivitis after 7 days of intervention. METHODS: This is a phase 2, double-blind, controlled, multicenter, clinical trial of 300 subjects, randomized to either a 3 dosing regimen of pazufloxacin 0.6% ophthalmic solution (twice a day [BID], n = 90; 3 times a day [TID], n = 76; 4 times a day [QID], n = 68), moxifloxacin 0.3% TID (n = 82), or gatifloxacin 0.5% TID (n = 72). Follow-up was set on days 0, 3, and 7. Assessments of ocular signs were performed, both anterior and posterior segments. The primary outcome measures included conjunctival culture and clinical signs. Safety variables included adverse events (AEs), lisamine green, fluorescein ocular surface stains, and clinical signs of tolerability. RESULTS: After intervention, bacterial eradication was reported in all groups: pazufloxacin BID 79%, pazufloxacin TID 84%, pazufloxacin QID 84%, moxifloxacin 80%, and gatifloxacin 82%. There were no significant differences between treatments. Similar results were reported in clinical remission: pazufloxacin BID 89%, pazufloxacin TID 98%, pazufloxacin QID 92%, moxifloxacin 91%, and gatifloxacin 92% (P = 0.03 comparing pazufloxacin BID vs. TID). There were no differences between female and male responses. The AEs were not related to the interventions. CONCLUSIONS: A simplified dosing regimen was selected to follow the development of ophthalmic pazufloxacin based on its efficacy and safety profile. Pazufloxacin, 1 drop 3 times daily, showed similar rates of bacterial eradication and clinical remission compared with other fluoroquinolones.

BACKGROUND: Dry eye disease (DED) is multifactorial, affecting 5-34 % of the global adult population and reducing quality of life. The artificial tears or lubricants are the therapy most used for the treatment of DED, due to their low side effect profile, which attempt to modify the properties of the tear film. The aim of the present study was to evaluate the clinical efficacy of a fixed combination of xanthan gum and chondroitin sulfate preservative free on the ocular surface of patients with dry eye disease during 60 days of intervention. METHODS: A phase III, double-blind, masked, controlled, multicenter, clinical trial of 148 subjects, randomized to either a fixed combination of xanthan gum 0.09 % and chondroitin sulfate 0.1 % (XG/CS) ophthalmic solution (n = 76) or a fixed combination of polyethylene glycol 400 0.4 % and propylene glycol 0.3 % (PEG/PG) (n = 72). Subjects self-dosed four times daily during 60 days. Follow-up was set on days 2, 7, 15, 30 and 60. Assessments of anterior/posterior segment ocular signs were performed. The outcome measures included Schirmer test, tear film break-up time and OSDI score. Security variables included intraocular pressure, lisamine green and fluorescein ocular surface stains. RESULTS: The primary efficacy endpoints were similar between groups at baseline. After intervention time Schirmer test increased in both groups compared to baseline, XG/CS (6.4 ± 2.2 vs 11.0 ± 6.6; p = 0.002) and PEG/PG (6.5 ± 2.5 vs 10.5 ± 5.6; p = 0.019) respectively. Similar results were reported in the tear film break-up time in XG/CS (5.5 ± 2.1 vs 7.4 ± 2.9; p = 0.027) and PEG/PG (5.2 ± 2.0 vs 7.4 ± 2.7; p = 0.046) respectively. The OSDI score decreased to normal values in both groups, XG/CS (19.3 ± 7.4 vs 7.3 ± 5.9; p = 0.001) and PEG/PG (19.3 ± 7.5 vs 7.9 ± 8.2; p = 0.001) respectively. There was no significant difference between treatments for any parameter. Moreover, both groups decreased the presence of burning sensation, tearing, foreign body sensation, conjunctival hyperemia and photophobia. The adverse events were not related to the interventions. CONCLUSIONS: Xanthan gum/chondroitin sulfate preservative free showed similar clinical efficacy, evaluated with OSDI score, TBUT and Schirmer test compared to polyethylene glycol/propylene glycol in the treatment of dry eye disease.
