Retinopathy of prematurity (ROP), is a vasoproliferative retinal disorder unique to premature infants. It is a spectrum of disease which clinically varies from spontaneous regression to bilateral retinal detachment and total blindness. Laser photocoagulation is one of the treatment modalities when given in type 1 ROP improves structural and visual acuity outcomes. Green laser(532nm) and diode laser(810nm) are used for ROP treatment.

Studies in terms of anatomical and refractive parameters in ROP children treated with laser were done in the past. However, clarity on the factors leading to myopia in these children is still lacking.

Functional vision is the use of vision for particular purposes. Functional visual skills are required to carry out everyday activities. Functional visual assessment is done in patients with low vision to see the difference in the measured visual acuity(distance and near) and how the person use vision as these 2 factors are not usually related to each other.

Previous studies showed that visual stimulation in form of various designs have the potential to improve visual outcomes in children with visual impairment. Role of Visual stimulation in ROP children treated with Laser needs to be evaluated further.

Through this study a more comprehensive way of understanding ocular biometric parameters in relation to ocular morbidities associated with ROP with additional component of functional visual assessment in ROP children with laser is what we wish to perform.
