Background: The Red Reflex is described as the red to orange reflection of light from the fundus of the eye, observed while using a retinoscope or an ophthalmoscope. Red Eye Reflex Test is determined by the optical media transparency which includes vitreous humor, aqueous humor, cornea and tear film and reflection of light from the back of the eye (fundus) through optical media and into the aperture of the ophthalmoscope. Factors that will block or impede the passage of light through this transparent media or affects its reflection back from fundus will produce an abnormal Red Eye Reflex. Red Eye Reflex (RER) testing is important & effective tool for early detection of ocular abnormalities such as retinal abnormalities, cataract, retinoblastoma and glaucoma. Red reflex is cost effective, can be performed very easily, requires minimal setting, can screen important ocular abnormalities and facilitate their early detection with prompt intervention to prevent long term sequelae associated with the disease. Aim: To find out the diagnostic accuracy of Red Reflex test for diagnosing ocular abnormalities in newborns. Methodology: Ours will be a prospective cross-sectional study where RER examination will be performed within one week of birth of a newborn in a darkened and will correlate the examination findings with respect to ocular findings determined by ophthalmologist to determine its efficacy, sensitivity and specificity in detecting neonatal ocular abnormalities. Expected results: After completion of the study we will be able to determine the accuracy of RRT for ocular abnormality detection in the neonates. We will be able to determine the sensitivity, specificity, PPV & NPV of the red reflex test. If the specificity and the sensitivity is good then we can use RRT as a routine screening method for detection of intraocular abnormalities. Conclusion: To find the Red reflex Test efficacy in screening of the ocular abnormalities in the new born.
