Should parents be present during screening examinations for retinopathy of prematurity?

Purpose: To investigate whether parents should be present during screening examinations for retinopathy of prematurity (ROP) by investigating the anxiety levels of parents using two different approaches.

Methods: This cross-sectional and two-center study was carried out with the parents at the time of the first ROP screening examination of their premature infants. At one center, the parents accompanied the infants during the ROP examination (Group 1), and in the other center, they did not (Group 2).

Ophthalmologic approach to babies with cerebral visual impairment.

Background: Cerebral visual impairment (CVI) is an increasingly common type of visual disturbance in infants and children. The increased incidence is associated with improved neonatal intensive care services and survival of premature infants, especially in developed countries and our country. For accurate ophthalmological evaluation, it is important to know the behavioral responses to visual stimuli that are unique to CVI such as color preference, need for movement, visual latency, visual field preference, and difficulty in visual complexity.

Aim: To investigate the effects of diode laser treatment on ocular biometric parameters in premature infants with retinopathy of prematurity (ROP).

Methods: Premature infants who received diode laser treatment for ROP (=68) and premature infants with spontaneous regressed ROP without treatment (=50) were performed longitudinal ocular biometric measurements including anterior chamber depth, lens thickness and axial length as follows: 1d prior to laser treatment, and 3, 6, 9, and 12mo after the laser treatment.

Results: The mean birth weight, gestational age and initial examination time values were 936.

Retinal choroidal and retinal nerve fiber layer thickness in former preterm and full-term infants aged 4 to 8 years.

Purpose: To compare the retinal thickness at the fovea center, peripapillary retinal nerve fiber layer (RNFL) thickness and choroidal thickness (CT) in former preterm and full-term infants.

Methods: A total of 121 healthy children aged 4-8 years were divided 4 groups: group 1; children born on time, group 2; preterm children without a history of retinopathy of prematurity (ROP), group 3; preterm children with a history of spontaneously regressed ROP and group 4; preterm children who underwent diode laser photocoagulation for ROP. The retinal thickness at the fovea, peripapillary RNFL thickness at global, superior, inferior, nasal and temporal quadrants and submacular CT at 7 different points were measured by using spectral-domain optical coherence tomography.

The outcomes of 326 external dacryocystorhinostomy operations in children with dacryostenosis - 30-year experience of an oculoplastic surgeon.

Purpose: To report demographic features and surgical outcomes of 320 children undergoing external dacryocystorhinostomy for dacryostenosis.

Methods: We performed a retrospective evaluation of the records of patients aged <16 years who underwent external dacryocystorhinostomy. Patient demographic features and success rates of the operations were analyzed from the data records.

Short- and long-term effects of zinc treatment on lacrimal gland histopathology and tear functions tests in radioiodine-administered rats.

Purpose:: To investigate the short-term (1 week) and long-term (8 weeks) protective effects of zinc administration on radioiodine (RAI)-induced lacrimal gland damage of rats.

Methods:: A total of 40 rats were divided into two groups: an RAI group (n=20), which was administrated a single dose of 3 mCi of 131I and 1 mL physiologic saline for 7 days by gastric gavage, and a zinc group (n=20), which received a single dose of 3 mCi of 131I and 1 mL of physiologic saline containing zinc sulfate at a concentration of 10 mg/kg concentration for 7 days by gastric gavage. All rats underwent tear function tests before and 1 week after RAI administration.

Maternal Diabetes as an Independent Risk Factor for Retinopathy of Prematurity in Infants With Birth Weight of 1500 g or More.

Purpose: To evaluate the relationship between maternal diabetes and the development of retinopathy of prematurity (ROP) in infants with a birth weight of 1500 g or more.

Design: Retrospective case-control study.

Methods: Data of 78 premature infants from diabetic mothers were compared with data of 258 controls.

Prostaglandin E Levels of Aqueous and Vitreous Humor in Ketorolac 0.4% and Nepafenac 0.1% Administered Healthy Rabbits.

Purpose: To compare the lowering effects of ketorolac 0.4% and nepafenac 0.1% on aqueous and vitreous humor prostaglandin E (PGE) levels in rabbits.

Successful treatment of ligneous conjunctivitis with topical fresh frozen plasma in an infant.

A 6-month-old female infant presented to our clinic with bilateral eyelid swelling, yellowish-white membranes under both lids, and mucoid ocular discharge. Her aunt had similar ocular problems that were undiagnosed. The conjunctival membranes were excised and histopathological investigation of these membranes showed ligneous conjunctivitis.

The relationship of birth weight, gestational age, and postmenstrual age with ocular biometry parameters in premature infants.

Purpose: To analyze ocular biometry parameters and evaluate their relationship with gestational age, birth weight, and postmenstrual age in prematurely born infants.

Methods: The right eyes of 361 premature infants born before the 36th gestational week were evaluated. Birth weight, gestational week, and gender were recorded.

The intraocular pressure and central corneal thickness in healthy premature infants.

Purpose: To describe the normal values of intraocular pressure (IOP) and central corneal thickness (CCT) in healthy premature infants.

Methods: Infants of <32 weeks' gestational age who underwent screened for retinopathy of prematurity were prospectively enrolled. The same ophthalmologist measured IOP by applanation tonometry and CCT using ultrasonic pachymetry.

Effect of allogeneic limbal mesenchymal stem cell therapy in corneal healing: role of administration route.

Aims: To investigate whether allogeneic limbal mesenchymal stem cell (LMSC) therapy affects corneal healing after a severe chemical burn and whether the route of administration of LMSCs differs in its therapeutic effect in this respect.

Methods: A total of 60 Sprague-Dawley rats with clinically proven alkali injury were divided into four equal groups (n = 15) as follows: group 1: 2 × 10(5) cells/drop LMSCs, topically applied 6 times a day for 2 days; group 2: 2.4 × 10(6) cells in 0.

Analysis of the horizontal corneal diameter, central corneal thickness, and axial length in premature infants.

Purpose: To determine the horizontal corneal diameter, central corneal thickness, and axial length in premature infants.

Methods: Infants with a birth weight of less than 2,500 g or with a gestation period of less than 36 weeks were included in the study. Infants with retinopathy of prematurity (ROP) were allocated to Group 1 (n=138), while those without ROP were allocated to Group 2 (n=236).

Reducing the histopathological changes of radioiodine to the lacrimal glands by a popular anti-oxidant: lycopene.

Purpose Of The Study: Radioiodine (RAI) has been used for the treatment of hyperthyroidism and well-differentiated thyroid carcinoma for more than 70 years. Lycopene is an anti-oxidant, which is plentiful in red fruits. The purpose of this study was to investigate the possible inhibitory effect of lycopene on the RAI-induced acute histopathological changes in rat lacrimal glands.

The effect of short-term vitamin E against radioiodine-induced early lacrimal gland damage.

Unlabelled: Radioiodine (RAI) is a well-known radionuclide which is used in vivo both for diagnostic and therapeutic purposes, particularly for the treatment of hyperthyroidism and thyroid cancer. Vitamin E is a well-known antioxidant vitamin. The aim of this study was to evaluate whether there was a protective effect of short-term vitamin E on RAI-induced lacrimal gland early damage in experimental animal models.
