Purpose: To search the relationship between serum neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and systemic immune-inflammation index (SII) values with the development of retinopathy of prematurity (ROP) and the requirement for laser treatment.
Methods: This retrospective cohort study was carried out with 195 preterm infants between 2012 and 2023. The NLR, PLR, LMR, and SII values were calculated on both the first day and at the end of the first month after birth.
Comparison of choroidal structural changes between term and preterm children with and without retinopathy of prematurity.

February 2024
Article Synopsis
- The study aimed to assess how prematurity and treatment for retinopathy of prematurity (ROP) affect choroidal structure in children aged 6-11 years, comparing results between preterm and term children.
- A total of 36 term and 52 preterm children were examined, measuring choroidal thickness and vascularity using specialized imaging techniques.
- Findings revealed that while subfoveal choroidal thickness was similar in both groups, the choroidal vascularity index (CVI) was significantly higher in term children, suggesting that prematurity negatively impacts choroidal vascularity, making CVI a more reliable measurement for evaluating ROP-related effects.
In this study, we aim to present a case with dural carotid-cavernous fistula mimicking thyroid orbitopathy. The differential diagnosis of red-eye is very coamplex, and the caregiver should distinguish between all diagnoses.

Methods: A total of 48 eyes of 24 patients (13 males, 11 females) with RP prescribed VPA were included. The length of VPA treatment was 6-12 months (mean 9.

Schwannomas (neurilemmomas) are benign neurogenic tumours of peripheral nerves. They originate from Schwann cells, which form the neural sheath. Although Schwannomas and neurofibromas are the most common primary peripheral nerve tumours, Schwannomas are rarely observed in ophthalmic areas.

December 2016
Article Synopsis
- This study aimed to investigate how caffeine affects the eyes of healthy individuals by examining ocular changes after caffeine consumption.
- Conducted with 17 university students, the research used optical coherence tomography (OCT) to measure choroidal thickness at various points after participants consumed either caffeine or a placebo.
- Results indicated that caffeine intake significantly reduced choroidal thickness, while intraocular pressure and ocular pulse amplitude remained unchanged.
Purpose: To investigate the association between central choroidal thickness (CT), axial length (AL), age, gender, and refractive error in a healthy pediatric population using optical coherence tomography (OCT).
Methods: This institutional study involved 137 healthy children (57 boys, 80 girls) aged between 4 and 18 years. Each child underwent a dilated eye examination, cycloplegic refraction, and AL measurement using a Nidek AL-Scan optical biometer.
Article Synopsis
- The study compared the anterior chamber depth (ACD) measurements of the Nidek AL-Scan and the Galilei Dual Scheimpflug Analyzer in a controlled setting at Turgut Ozal University Medical Faculty in Turkey.
- Sixty-three patient eyes were analyzed, revealing that the Galilei measured longer ACD values on average than the Nidek, with a statistically significant difference in their measurements (P = 0).
- The interobserver reliability was high for both devices, but despite the statistical difference, the clinical significance of the ACD variation was minor, suggesting further research is needed on its impact in contexts like intraocular lens calculations.
Article Synopsis
- The study aimed to analyze choroidal thickness (CT) in eyes with hyperopic anisometropic amblyopia compared to fellow non-amblyopic and age-matched normal eyes using SD-OCT.
- A total of 106 participants, including 53 with amblyopia and 53 controls, underwent eye examinations to measure axial length and choroidal thickness in the subfoveal area.
- Results showed that the subfoveal CT in amblyopic eyes was significantly thicker than both fellow and control eyes, indicating that choroidal thickness is affected in hyperopic anisometropic amblyopia.
Purpose: The aim of this study is to show the effects of smoking on retina layers, especially retina nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer complex (GCIPL).
Materials And Methods: Participants smoking for more than 10 years at least 1 pack of cigarettes a day and a control group, both including participants between ages of 20 and 50 years with no other systemic or ocular diseases were studied. After normality tests, an independent sample t test was used to analyze the differences in age, sex, spherical equivalent (SE), intraocular pressure (IOP), axial length (AL), GCIPL and RNFL values between the groups.
Background: In our study, we aimed to show the effects of smoking on choroidal thickness and ocular pulse amplitude. It is known that the anatomy and physiologic functions of the choroid is important in ocular diseases like glaucoma and age-related macular degeneration. Choroidal thickness is measured by the spectral domain optical coherence tomography (SD-OCT).
