Table 1 Modified Meller and Tseng's grading system for conjunctivochalasis used in the present study*

From: Assessing the severity of conjunctivochalasis in a senile population: a community-based epidemiology study in Shanghai, China

  Basic grading criteria   Supplement grading criteria   
  Folds versus Tear Meniscus Height(F) Symptoms(S) Punctual Occlusion and Tear Meniscus Height(O) Height/extent of chalasis Changes in Downgaze(G) BUT(B)
0 No persistent fold No Without occlusion No difference >= 10s
1 Single, small fold No Without occlusion and tear meniscus height <= 0.3 mm No difference >= 10s
2 Two or more folds and not higher than the tear meniscus Mild Nasal location with partial occlusion and irregular tear meniscus mildly increases in downgaze 6-9s
3 Multiple folds and higher than the tear meniscus Medium Nasal location with complete occlusion and discontinuous tear meniscus Significant increase in downgaze 4-5s
4 Multiple folds, higher than the tear meniscus, and causing exposure problems Severe Nasal location with complete occlusion and no tear meniscus Severely increase in downgaze <= 3s
  1. *Symptoms indicate dryness, foreign body sensation, and epiphora, evaluated by the patients themselves BUT:break-up time(seconds)
  2. This grading system for conjunctivochalasis obeys the following rule: if the clinical appearance of a certain patients corresponds to F2 + S2, or F2+ any two of O2, G2 and B2, the patient will be diagnosed as Grade II conjunctivochalasis, and so forth with Grade0, Grade I, Grade III, or Grade IV.
  3. Grade II, Grade III, and Grade IV are also defined as "clinical significant conjunctivochalasis".
