Purpose: To determine the intraocular pressure (IOP) profile during and after systemic dexamethasone treatment in preterm very low birth weight (VLBW; <1500 g) infants.

Design: A cohort study at a university-affiliated tertiary neonatal center.

Participants: Twenty-seven VLBW infants who received a 3-week dose-tapering course of systemic dexamethasone for treatment of bronchopulmonary dysplasia were consecutively enrolled over a period of 32 months.

Purpose: To establish a normative range of intraocular pressure (IOP) in preterm infants and to identify important perinatal factors that could affect the IOP during the early weeks of neonatal life.

Methods: The IOP of 104 preterm infants, with a median (interquartile range) gestational age of 29.8 (28.

Purpose: The purpose of this study was to study the prevalence of peripheral retinal findings in adult Chinese patients with high myopia (refraction < or = -6.00 D) and to investigate the correlation between the retinal lesions and the severity of myopia or axial length.

Methods: A cross-sectional prevalence survey screening was conducted in high ethnic Chinese myopes with refractions equal to or less than -6.

Objective: To study the safety and efficacy of photodynamic therapy (PDT) with verteporfin in treating subfoveal choroidal neovascularization (CNV) of idiopathic cause.

Design: A prospective, noncomparative, consecutive, open-label, two-center, interventional case series.

Participants: Patients aged 50 years or younger with the diagnosis of idiopathic CNV by exclusion of other related causes together with the CNV extending under the geometric center of the foveal avascular zone.

Background: To compare the anatomical and visual outcome in primary idiopathic macular hole surgery with or without indocyanine green (ICG) stained internal limiting membrane (ILM) peeling.

Methods: The medical records of the last 40 consecutive eyes receiving primary idiopathic macular hole surgery with gas as internal tamponade performed by a single surgeon were retrospectively reviewed and analysed. All eyes had a follow-up period of at least 6 months.

This longitudinal prospective study aimed to investigate the relationship between pituitary-adrenal responses and severity of retinopathy of prematurity (ROP) in 92 preterm, very low birth weight infants < or = 30 wk gestation. The human corticotropin releasing hormone stimulation test was performed on these infants at D 7 and 14 of postnatal life. Univariate analysis revealed significant associations between severity of ROP and gestational age (r = -0.
