ROP is not a new disease but the number of babies at risk for ROP is increasing because of the improvement in neonatal care and better practices in NICU. As such the management of babies with ROP is a combined effort of neonatologists, ophthalmologists and a host of other health care personnel. Accordingly the theme for the World prematurity day 2020 which falls on 17^th November is “Together for babies born too soon – Caring for the future”

Which babies are at risk for ROP?

There are many guidelines with regard to ROP. The guidelines stated below are best suited for Indian babies

• Children born with birth weight less than 2000 grams·
• Children born before gestational age of 34 weeks·
• Children who have been exposed to oxygen for more than 30 days

Other factors where screening must be done for children with birth weight <2000 grams or Gestational age < 37 weeks include·      

• Respiratory distress syndrome·
• Multiple blood transfusions·
• Infection·
• Apnoeic episodes·
• Multiple births·
• Intraventricular haemorrhage·
• Any other case where the paediatrician has concerns

When to screen for ROP?

All children must be screened at least once by 31 weeks gestational age or 3-4 weeks after birth (whichever is earlier)

If the baby has a birth weight < 1200grams or is born before 24 weeks gestational age, examination must be scheduled at 2- 3 weeks post-delivery.

There is no need for examination within 2 weeks of delivery as the normal retinal maturation would not be completed

Preparation for examination:

The baby must be dilated using half diluted commercially available tropicamide- phenylephrine combination.  Recently, some companies have come out with ready to use drops where the constituent drugs have been diluted to levels which are deemed safe for the babies. 2-3 instillations of drops are applied 5 minutes apart and examination must be done after 30 to 45 minutes. Any excess drops on cheek must be immediately wiped off to prevent systemic absorption.

What happens after the examination?

The eye specialist examining the baby would advise based on the findings inside the eye. The following outcomes would be possible

1. Retina is fully matured – Baby will need a follow up after 6 months or 1 year
2. Retina is immature but there is no ROP – Baby will need close follow up
3. ROP is present but is not severe – Baby will need close follow up
4. ROP is present and severe – Baby will need LASER / intraocular injections /surgery in any possible combination

Can we delay the LASER / Surgery as the baby is small?

Surgery/LASER cannot be delayed as ROP is a rapidly progressing condition and any delay might only end up causing the condition to worsen, however, both LASER and surgery would be conducted under strict monitoring keeping in mind the fragile state of the baby and hence will not affect the baby adversely.

Will the baby recover after the LASER/Surgery?

ROP is the manifestation of the baby’s systemic condition in the eye. Recovery after LASER/Surgery would depend upon how quickly the systemic condition stabilizes.

Will the baby have good vision after LASER/Surgery?

If intervention is done in the early stages of ROP, when the central part of the retina is not yet affected, vision is usually not affected. In the long term, the baby might need to use some glasses in the future but they will enjoy good vision with the same. If the ROP is severe or affects the central part of the eye, the visual outcome might be lesser.

However, one must remember that without any intervention, the child might have gone completely blind. So, in a nut shell all the babies at risk must be examined and those babies needing LASER/surgery must be treated at the earliest to get the best results for the baby.

The post Retinopathy of prematurity – is it a new disease and how to prevent blindness? appeared first on Health Vision.

It is an annual day of awareness held on the second Thursday of October, to focus on global blindness and vision impairment. It falls on 8 th October 2020. It is coordinated by International Agency for prevention of blindness (IAPB) under WHO VISION 2020 , The Right to Sight , Global initiative. This year the theme is ‘ Hope in Sight ’

More than 75% of visual impairment is avoidable. After Cataract, Refractions Errors and Diabetic eye disease comes Glaucoma. The blindness due to these major problems can be prevented. Glaucoma is the leading cause of irreversible blindness in India and at least 12 million people affected and nearly 1.2 million people blind from the disease. More than 90% of glaucoma cases remain undiagnosed.

Glaucoma can be prevented by regular eye check up

Early diagnosis and treatment of Glaucoma is the main goal to prevent blindness. This world sight day, the main focus is on the awareness of importance for regular eye check up in people above 40 years ,

1. Family history of Glaucoma
2. History of seeing Haloes around lights
3. History of long time use of steroids either locally or systemically.
4. History of myopia or frequent change of glass power.
5. Any history of injury or operation to the eyes

The public are requested to take note of these above points and have a complete eye examination by an ophthalmologist for early diagnosis of Glaucoma and prevent their eyes from going blind.

A slit lamp examination, applanation tonometry, visual field testing and dilated fundus examination are the key tests to be undergone periodically for prevention of blindness. Glaucoma can be prevented if diagnosed early and further progress can be stopped by local eye drops medications, LASER treatment to the eyes or surgical interventions.

Therefore, the public are requested to take this initiative of  ‘Hope in Sight’ on this world sight day by IAPB and get their eyes examined for Glaucoma and other eye disease for early detection and prevention of the problem. An appeal to the public in this Covid times – we at Maxivision super speciality eye hospital are taking all precautions for a safe eye examination or surgery to the patient and all our staff and doctors are following the covid protocols sincerely.
