Classification and severe forms of ROP

In this webinar we will learn about classification and severe forms of ROP
How to classify ROP? Severe forms of ROP, Consequences
International Classification of ROP (ICROP) is used for classifying ROP. ROP is categorised based on the severity of the disease into stages (1-5), location of the disease into 3 zones (Zone 1-3) and the presence of plus disease.
Zone 1: a circle whose radius is twice the distance from the centre of the optic disc to the centre of macula, Zone 2: a circle whose radius is the distance from the centre of the optic disc to the nasal margin of the retina, Zone 3: The remainder of the retina, from Zone II to ora-serrata on nasal side and equator on temporal side.
Stage 1- Thin white line of demarcations Stage 2-Addition of depth and width to the demarcation line (Ridge) Stage 3-Presence of extra retinal fibro vascular proliferation Stage 4-Partial retinal detachment beginning at the ridge, not involving macula(4A) and involving macula (4B) Stage 5 Complete retinal detachment
It is one of the severe form of ROP which is characterised by significant level of venous dilation and arteriolar tortuosity of the posterior retinal vessels. One important point which should be remembered is that if there is poor pupillary dilatation (rigid pupil), you should suspect plus disease
It is a rapidly progressing, severe form of ROPin the smallest and most immature infants with prominence of plus disease. Ill-defined, mild appearing and easily over looked retinopathy, There is a risk of early retinal detachment in APROP
Refractory errors, Squint, Unilateral or bilateral Blindness, Late retinal detachment (6 months-31 years), Glaucoma
ROP is classified based on the severity, location and extent of the disease. The presence of plus disease and APROP needs urgent intervention in the form of laser or surgery. Screening and timely intervention will reduce dire consequences of ROP

1. Learning objectives

► To learn about the

      ♦ classification of ROP
      ♦ severe forms of ROP
      ♦ consequences of ROP

2. Classification of ROP

► International Classification of ROP (ICROP) is used for
    classifying ROP

► ROP is categorised based on
      ♦ the severity into stages (1-5)
      ♦ location into 3 zones (Zone 1-3)
      ♦ the presence of plus disease

3. Location

4. Severity

6. Plus disease

► Increased venous dilation
► Arteriolar tortuosity of the posterior retinal vessels
► If there is poor pupillary dilatation (rigid pupil), you should
    suspect plus disease

7. Aggressive Posterior ROP (AP-ROP)

► Rapidly progressing, severe form of ROP in the smallest
     and most immature infants
► Prominence of plus disease
► There is risk of early retinal detachment

8. Consequences of ROP

► Refractive errors

► Squint

► Unilateral or bilateral blindness

► Late retinal detachment (6 months-31 years)

► Glaucoma

9. Key messages

► ROP is classified based on the severity, location and extent
    of the disease

► The presence of plus disease and APROP needs urgent
    intervention in the form of laser or surgery

► Screening and timely intervention will reduce dire
    consequences of ROP

5. Severity - 01

► Stage 1 - Thin white line of demarcation's

► Stage 2 - Addition of depth and width to the demarcation line
    (Ridge)

► Stage 3 - Presence of extra retinal fibro vascular proliferation

► Stage 4 - Partial retinal detachment beginning at the ridge,
    not involving macula (4A) and involving macula (4B)

► Stage 5 - Complete retinal detachment
