Introduction: The aim of the study was to analyse the clinical and demographic features of infants with gestational age (GA) of 32-37 weeks and birth weight (BW) of >1,500 g who developed treatment requiring retinopathy of prematurity (ROP).
Methods: Data on the infants with a GA of 32-37 weeks and BW >1,500 g who developed treatment requiring ROP (TR-ROP) were collected retrospectively from the 33 ROP centres in Turkiye. GA, BW, type of hospital, neonatal intensive care units (NICUs) level, presence of an ophthalmologist and neonatologist in the same hospital, length of stay in NICU, duration of oxygen therapy, comorbidities, type of ROP, and timing for TR-ROP development were analysed.
This study aims to examine the psychometric properties of questionnaires related to cerebral visual impairment (CVI) in school-age children with cerebral palsy (CP). Additionally, it proposes an application process based on motor functionality for occupational therapists. A total of 288 children with CP were recruited for the study and administered the CVI Motor Questionnaire (CVI-MQ).

The distribution of diagnosis, accompanying ocular findings, visual acuity of the children both for near and distance with and without low vision devices, and the methods of low vision rehabilitation (for distance and for near) were determined.
Purpose: To evaluate the effects of diode laser treatment on intraocular pressure (IOP) of premature infants with retinopathy of prematurity (ROP).
Patients And Methods: The premature infants who underwent retinal laser photocoagulation therapy for ROP, and gestational age-matched, birth weight-matched, and sex-matched premature infants with ROP which recovered spontaneously without any treatment were enrolled into the study. Anterior segment examination and longitudinal IOP and central corneal thickness measurements were performed 5 times as follows: 1 day before the laser treatment (T0), and 24 hours (T1), 1 week (T2), 1 month (T3), and 3 months (T4) after the laser treatment.
Background/aim: To evaluate refractive and strabismic results and the efficacy of intravitreal bevacizumab in retinopathy of prematurity (ROP) ineligible for laser therapy.
Materials And Methods: Thirty-nine eyes of 20 consecutive infants with high-risk prethreshold ROP (11 infants with Zone I and 9 infants with Zone II disease) who were ineligible for laser therapy due to systemic and/or ocular conditions were treated with intravitreal bevacizumab. Recurrent retinopathy was treated with laser ablation.
Background/aim: To investigate the biometric components and refractive errors in premature infants with or without retinopathy of prematurity (ROP).
Materials And Methods: Anterior chamber depth, lens thickness, vitreous length, and axial length were measured with an ultrasound biometer. Cycloplegic refraction was performed by streak skiascopy.
Background/aim: The aim of this study was to report the gestational age (GA) and birth weight (BW) distribution of premature babies who needed treatment for retinopathy of prematurity (ROP) and to assess the timing of the treatment.
Materials And Methods: The records of 9008 infants who were screened for ROP were examined and 556 infants who underwent laser therapy for ROP were reviewed. Sex, GA, BW, postnatal age, and postmenstrual (PM) age at the time of laser therapy were recorded.
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.

Subfoveal choroidal thickness was defined as the distance from the hyperreflective line of the outermost retinal pigment epithelium (RPE) to the innermost hyperreflective line of the choroidoscleral junction.
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.
