RESUMEN
Context: To evaluate the necessity of ocular screening in Type 1 diabetes mellitus (DM). Aims: This study aims to investigate the diabetes‑related ocular changes according to the glycosylated hemoglobin (HbA1c) level and duration of diabetes in children and compare the results with nondiabetic healthy children. Settings and Design: Observational cross‑sectional study designed by ophthalmology and pediatric endocrinology clinics. Subjects and Methods: Forty‑two children with Type 1 DM, 42 healthy gender‑ and age‑matched children as controls were enrolled. All patients underwent ophthalmic and physical examination, with a review of medical history and current medication. HbA1c level, best corrected visual acuity, intraocular pressure (IOP), central corneal thickness (CCT), tear break‑up time (BUT), Schirmer test, dilated fundus examination findings, central retinal thickness (CRT), and total macular volume (TMV) measurements were noted. Statistical Analysis: Descriptive statistics, Student’s t‑test, Mann–Whitney U‑test, Chi‑square test for comparison of the group parameters and correlation analyses (Spearman analysis) were performed with SPSS statistical software 17.0 (SPSS Inc., Chicago, IL, USA). Results: Type 1 DM group exhibited significantly reduced Schirmer test, increased IOP and decreased retinal thickness relative to the age‑matched control group (P < 0.05) but no statistically significant difference was found for the BUT (P = 0.182) and for the CCT (P = 0.495). The correlations between the age, duration, HbA1c and IOP, BUT, Schirmer test, TMV, CRT measurements did not reach statistical significance. Conclusions: More frequent screening may be needed for complications, including neuropathy‑related dry eye syndrome, IOP changes, and diabetic retinopathy in children with Type 1 DM.
RESUMEN
ABSTRACT Purpose: Comparison of laser therapy (LT) outcomes in patients with retinopathy of prematurity (ROP) followed up in our clinic and referred from other centers. Methods: Medical records of 1,856 ROP patients were retrospectively evaluated, and a total of 128 patients who underwent LT were included in the study. The study population was divided into the following two groups: patients who were followed up and treated in our clinic (group 1, N=45) and patients who were referred to our clinic from other centers (group 2, N=83). Data regarding birth weight, sex, gestational age, postnatal treatment time, disease localization, and stage were analyzed and compared between the two groups. Treatment success was defined by anatomic success 6 months after treatment. Results: Patients in the referred group presented with a more advanced disease (p<0.01), a lower treatment success rate (p=0.01), and a longer time interval between diagnosis and LT (p=0.04). Conclusions: The treatment success rate of ROP was significantly lower in referred patients because of the potential delay in LT and more advanced disease at the time of treatment initiation.
RESUMO Objetivos: A comparação dos resultados da terapia a laser (LT) em pacientes com retinopatia da prematuridade (ROP) acompanhados em nossa clínica e encaminhados por outras clínicas. Método: Os arquivos de 1.856 pacientes com ROP foram analisados retrospectivamente e um total de 128 pacientes submetidos à LT foram incluídos no estudo. A população do estudo foi dividida em dois grupos; os pacientes que foram acompanhados e tratados em nossa clínica (grupo 1, n=45) e os pacientes que foram encaminhados à nossa clínica por outros centros (grupo 2, n=83). Os dados referentes a peso de nascimento, sexo, idade gestacional, tempo de tratamento pós-natal, localização e fase da doença foram analisados e comparados entre os grupos. O sucesso do tratamento foi definido pelo sucesso anatômico no sexto mês após o tratamento. Resultados: Pacientes no grupo de pacientes encaminhados apresentaram doença mais avançada (p<0,01), taxa de sucesso inferior (p=0,01) e maior intervalo de tempo entre o diagnóstico e tratamento a laser (p=0,04). Conclusões: A taxa de sucesso do tratamento da ROP é significativamente menor em pacientes encaminhados por causa de possível atraso da LT e do estágio mais avançado da doença observado.
