Grading in Ophthalmologuy

How to grade everything in ophthalmology?

Grading in ophthalmology is an ever evolving concept. Some grading systems which is used commonly are as follows. 

Grading of Ptosis:

Ptosis is a drooping of the upper eyelid.
Marginal Reflex Distance MRD (Distance between Upper lid margin and corneal light reflex)
ptosis grading


Grading of Entropion:

Lid margin is inturned
Depending on degree of in turning,dividing into three grades.

  1. Grade 1: only posterior lid border is inrolled. 
  2. Grade 2: inturning of intermarginal strip. 
  3. Grade 3: whole lid margin including anterior border inturned

Grading of Ectropion

It is an outward rolling of lid margin.

  1. Grade 1: Only punctum everted
  2. Grade 2: Lid margin is everted and palpebral conjunctiva is visible.
  3. Grade 3: Fornix is visible

Grading of Hyphema:

Hyphemas can be graded from grade  I-IV
  • Grade 0: No visible layering, but red blood cells within the anterior chamber (microhyphema)
  • Grade I: Layered blood occupying less than 1/3 of the anterior chamber 
  • Grade II: Blood filling 1/3 to 1/2 of the anterior chamber 
  • Grade III: Layered blood filling ½ to less than total of the anterior chamber 
  • Grade IV: Total clotted blood, often referred to as blackball or 8-ball hyphema

Anterior Chamber (AC) Cells Grading:

AC Flares:

0  Complete absence
1+ Faint flare (barely detectable)
2+ Moderate flare (iris and lens still clear)
3+ Marked flare(iris and lens hazy)
4+ Intense flare(coagulate aqueous, no circulation, fibrin visible)

Grading of AC cells and flare

Van Herick’s AC Depth Grading:  

The peripheral anterior chamber depth (PACD) is compared to the adjacent corneal thickness (CT) and the presumed angle width is graded as follows:

Grade 4 (Wide open angle): PACD = 3 / 4 to 1 CT
Grade 3 (Mild narrow angle): PACD = ¼ to ½ CT
Grade 2 (Moderate narrow angle): PACD = ¼ CT
Grade 1 ( Extremely narrow angle): PACD < ¼ CT  
Grade 0 (closed angle): PACD = Nil

Posterior Sub Capsular Cataract (PSCC) Grading :

Diabetic Retinopathy Grading:

Hypertensive Retinopathy Gradings:

HTN retinopathy grading 

RAPD Grading 

1+ Weak initial constriction followed by greater redilation
2+ Initial pupillary stall followed by greater redilation
3+ Immediate pupillary dilation
4+ No reaction to light
