Description

Retinopathy of Prematurity (ROP) is a condition that affects premature newborns receiving oxygen therapy and causes retinal vascular and capillary growth. Gestational age and birth weight remain the primary screening criteria for this major cause of juvenile blindness, despite the fact that several other factors both increase the incidence and severity of disease progression. Cryotherapy, laser photocoagulation, and anti Vascular Endothelial Growth Factor (VEGF) therapy used early in the course of the disease have all improved visual results for patients; nevertheless, early diagnosis through screening is essential. This activity illustrates the importance of a multidisciplinary approach from conception onwards and demonstrates the keys to preventing ROP.

The Early Treatment for Retinopathy of Prematurity study identified a number of significant epidemiological risk factors for ROP. In this multicenter, randomised, prospective trial, the safety of early ablation of the peripheral retina was compared to that of traditional timing. Infants weighing less than 1251g had a 68% incidence of ROP in any stage. 14.9 million preterm newborns and 184,700 infants worldwide with any stage ROP in 2010. 20,000 of those affected went blind or suffered severe vision impairment, while 12,300 experienced mild to moderate visual impairment.

Gestational Age (GA) and birth weight are the two main risk factors for ROP that are currently understood birth weight. The risks of developing threshold ROP dropped by 27% for every 100g rise in BW and by 19% for every additional week in GA, according to a multicenter study of more than 4000 children with birth weights under 1251g.

Oxygen is a significant additional risk factor. As was already indicated, the use of additional oxygen in conjunction with atmospheric oxygen reverses physiologic hypoxia, which in turn causes retinal ischemia and the consequent overgrowth of retinal arteries in ROP. Additionally, the amount of oxygen given has a separate role as a risk factor for ROP, with higher O2 concentrations raising the likelihood of ROP. The risk of ROP increases every 12 hours with transcutaneous PO2 80mmHg.

Significant risk for severe ROP is associated with the length of oxygen therapy. Assisted reproduction, childbirth away from a study center hospital, multiple gestations, maternal diabetes, medication use, age, and smoking are all potential risk factors.

Premature newborns that have Retinopathy of Prematurity (ROP), an eye vasoproliferative condition, are affected. In its more severe forms, it causes severe visual impairment or blindness, both of which come at a high financial cost to the community as well as a high personal cost to the affected child because they interfere with their normal motor, language, conceptual, and social development, which is exacerbated once they start formal schooling. The position in relation to the optic nerve, the size of the growing vasculature, and the disease's progressive staging are all covered by the International Classification of ROP. The first stage is the mildest, whereas stages four and five denote partial and complete retinal detachment, respectively. Any stage of ROP may be accompanied by symptoms of ongoing ROP activity, which are referred to as "plus" symptoms. In zones I or II, "threshold" ROP is defined as 5 consecutive or 8 cumulative clock hours of stage 3 ROP in the presence of "plus" illness, which indicates an increased risk of retinal detachment.

In an effort to lower the incidence of childhood blindness, the Global Initiative for the Elimination of Avoidable Blindness has targeted ROP for prevention and treatment. Although the prevalence of childhood blindness is very high in nations with Infant Mortality Rates (IMR) greater than 60 per 1000 live births, such as sub-Saharan Africa, very little or no ROP is recorded in these nations due to the scarcity of facilities for providing intensive care to premature infants and their low survival rates. ROP is responsible for 6%-20% of childhood blindness in industrialised nations with IMRs of fewer than 10 per 1000 live births. ROP is now recognised as a significant contributor to childhood blindness in nations with IMRs between 10 and 60 per 1000 live births. In nations where blind children have a high incidence of intellectual handicap (up to 75%) the percentage of blindness brought on by ROP may be understated. Depending on the degree of postnatal care offered, incidence may differ throughout regions within the same nation.

One of the main causes of blindness and visual morbidity in infants globally continues to be retinopathy of prematurity. In the future decades, the prevalence of ROP will probably continue to rise as healthcare systems develop and our understanding of the condition advances. This study provides an overview of the present state of ROP diagnosis and management, as well as existing and potential applications of telemedicine, artificial intelligence, and imaging modalities. The following are some of this study's main points.

With the third edition of ICROP, classification schemes are still developing. It is impossible to use a universal strategy for ROP screening; instead, regional variations and the unique clinical trajectory of the patient group must be taken into account. Globally, the use of telemedicine is increasing and is increasingly crucial in the diagnosis and treatment of ROP. For the clinical treatment of ROP patients, artificial intelligence is now under investigation. Treatment using laser photocoagulation is still effective. Anti-VEGF is now more widely available and is frequently used as a treatment by doctors. Newer, more affordable imaging methods have been created that enable telemedicine and possibly AI to play a larger part in the management of ROP.
