Purpose: To describe a new modified technique in the treatment of ROP (retinopathy of prematurity) using the RetCam 3 digital imaging system - Camera-Assisted Laser photocoagulation and Cryotherapy of the Retina (CALCR).
Methods: From Nov 2011 to Oct 2013, 113 infants were diagnosed with ROP. The average post-conceptual age (PCA) at the time of diagnosis was the 35(th) week of PCA; the average birth weight was 1,041 g. According to the ETROP study, the avascular part of the retina of infants with high-risk prethreshold ROP was treated with a trans-scleral diode laser or with cryotherapy within 48-72 h after the diagnosis. The intervention was performed under general anaesthesia under the direct visual control of the RetCam 3.
Results: The CALCR technique was used in all 23 infants (46 eyes) diagnosed with high-risk prethreshold ROP. The average age of these infants at the time of the intervention was the 38(th) week of PCA. None of the infants had any serious complications during the CALCR procedure. In contrast to the traditional technique, CALCR offers many benefits: the image of the retina is real, magnified and not inverted, it shows details of the retina in a high resolution, photo and video documentation is available. Therefore the preoperative, intraoperative and postoperative condition of the retina can be precisely evaluated and compared on a fully standardized basis.
Conclusions: The CALCR procedure represents a new technique providing greater accuracy when targeting the avascular part of the retina, enables better visualisation and more precise treatment, and reduces the risk of unintended damage to healthy retinal tissue.

Purpose: The purpose of this study was to assess the refractive outcomes of patients who underwent indirect laser photocoagulation for prethreshold type 1 retinopathy of prematurity (ROP) and high-risk type 2 prethreshold ROP in comparison to conservatively managed low-risk prethreshold type 2 ROP.
Methods: A retrospective analysis was carried out on infants screened for ROP between the years 2015 and 2020. Surviving children who had developed ROP in one or both eyes and received diode laser photocoagulation and those with conservatively managed regressed type 2 ROP who underwent at least one cycloplegic retinoscopy were included in the study.

Aim: To conduct a comparative analysis of risk factors for retinopathy of prematurity (ROP) in single- and multiple-born neonates.
Methods: In a retrospective evaluation of 521 premature neonates, encompassing singletons, twins, and triplets born at or before 34 weeks of gestational age with a birthweight of less than 2000 g and who completed the ROP screening program, between 2020 and 2023, in outpatient referral ROP screening clinic affiliated by Shiraz University of Medical Sciences, were included. Neonates with the eligibility criteria were enrolled in the screening program from 28 days old age and followed up to discharge or treatment based on national ROP screening guideline.

Purpose: This study aimed to ascertain the efficacy and safety of an additional posterior to the ridge laser for treatable zone 2 stage 3 retinopathy of prematurity (ROP).
Methods: This study was a retrospective chart review of infants undergoing laser treatment for ROP at a single center from March 2014 to March 2022. The chart review specifically searched for infants treated for zone 2 stage 3 ROP with plus disease, where additional posterior to the ridge laser was performed.

Background/aim: The aim of the study is to describe the efficacy and to determine the functional outcome in terms of visual acuity and refractive defect of a single dose of intravitreal bevacizumab in patients with high-risk ROP type 1.
Methods: In this retrospective clinical study patients diagnosed between December 2013 and January 2018 with high-risk pre-threshold ROP type 1 and treated with intravitreal bevacizumab were selected. All patients were treated following the established protocol at our centre.

Purpose: To analyze the weekly rate of retinal vascular growth in treatment-naïve babies with various stages of retinopathy of prematurity (ROP) and validate if this could be a predictor of treatment need.
Methods: Retrospective review of medical charts and retinal images of babies with various stages of ROP. The images were enhanced using red-green image enhancement software.
