Purpose: To investigate the potential benefits and practicality of ultra - wide field (UWF) imaging and intravenous UWF fluorescein angiography (IV UWF - FA) in infants with retinopathy of prematurity (ROP) using an Optos® California device.

Methods: This retrospective study involved 46 infants with a history of ROP who underwent UWF imaging with or without IV UWF - FA. ROP characteristics were identified using UWF color imaging. Retinal vascular findings following treatment were also assessed at IV UWF - FA analysis. All imaging sessions were performed under topical anesthesia without sedation. Main outcomes were the appearance of ROP at UWF color imaging and IV UWF-FA analysis, including status of ROP, neovascularizations, presence of plus disease, retinal vascular details, and resolution after treatment.

Results: Seven (three girls) of the 46 infants (22 girls) underwent IV UWF-FA. Twelve IV UWF-FA sessions were performed in total. The oldest infant during IV UWF-FA analysis was at 55 postmenstrual weeks. Clinical characteristics of disease were easily identified at UWF color imaging. IV UWF-FA images also clearly revealed non-perfused retinal areas, fluorescein leakage, macular edema, retinal vascular abnormalities, and the status of the peripheral vascular termini. Complications of IV UWF-FA occurred in one infant in the form of patchy yellow skin discoloration around the injection site which completely disappeared on the first day following the procedure.

Conclusions: Providing a high resolution panoramic view of the retina in a single image capture with no need for contact with the cornea appear to represent potential advantages of UWF imaging in infants with ROP. IV UWF-FA also seems to be a safe procedure which can be performed under topical anesthesia and that shows detailed retinal vascular alterations in patients with ROP.

Effect of Body Position on Intraocular Pressure Measured by Rebound Tonometer in Healthy Children.

Turk J Ophthalmol 2020 10;50(5):271-274

University of Health Sciences Turkey, Fethi Sekin City Hospital, Clinic of Ophthalmology, Elazığ, Turkey.

Objectives: To evaluate the effect of body position on intraocular pressure (IOP) measurement in the pediatric age group.

Materials And Methods: Children whose general condition was healthy and ophthalmic examination was within normal limits were included. Forty-nine eyes of 49 pediatric patients were included in the study. IOP was measured with an ICARE rebound tonometer (ICARE PRO; ICARE, Helsinki, Finland) while patients were in standing, sitting, and supine positions. Differences between the consecutive measurements were compared statistically.

Results: Twenty-two of the 49 patients were female, 27 were male. The mean age was 9.61±2.66 (5-15) years. Mean IOP values in the standing, sitting, and supine positions were 18.81±2.97 (11.6-26.2) mmHg, 18.88±3.44, (12-28.2) mmHg, and 19.01±2.8 (13.5-25.9) mmHg, respectively. There were no statistically significant differences in pairwise comparisons of the measurements taken in the different positions (p=0.846, p=0.751, p=0.606). There was a statistically significant correlation between corneal thickness and intraocular pressure values in all measurements (p=0.001, r=0.516).

Conclusion: IOP values measured with the ICARE rebound tonometer in healthy children are not affected by body position.

The role of simple inflammatory blood parameters in idiopathic epiretinal membrane patients.

Int Ophthalmol 2021 Jan 26;41(1):107-112. Epub 2020 Aug 26.

The State Hospital of Bayburt, Bayburt, Turkey.

Aim: To evaluate the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in idiopathic epiretinal membrane (IERM) patients, and their relations with visual acuity.

Method: Fifty-seven IERM and 51 control patients were included. All patients underwent comprehensive ophthalmological examination and complete blood count tests, and NLR and PLR values were calculated. Patients with IERM were compared with the control group, and associations with visual prognosis were evaluated. These ratios' cut-off values for IERM were also calculated RESULTS: NLR values were statistically significantly higher in the IERM group than in the control group (p = 0.001). No significant difference was observed between the IERM and control groups in terms of PLR (p = 0.43). No significant correlation was determined between visual acuity and NLR or PLR (r = 0.05, p = 0.66; and r = 0.18, p = 0.16, respectively). The cut-off value for NLR was 1.91.

Conclusion: Patients with IERM showed significantly increased NLR compared to control subjects suggesting that IERM patients may be prone to have high NLR values.
