TI  - Unilateral congenital ptosis: compensatory head posturing and amblyopia.
PG  - 196-200
AB  - Patients with unilateral congenital ptosis often adopt chin elevation to maintain 
      fusion. This compensatory head posturing has been considered a sign of fusion, 
      thus indicating a low risk for amblyopia. To evaluate this sign, we reviewed the 
      charts of 11 preverbal children with unilateral congenital ptosis who had 
      straight eyes and appropriate compensatory head posturing to maintain binocular 
      vision. Four additional patients with unilateral ptosis and no compensatory head 
      posturing were tested for comparison. All patients had undergone an examination 
      and had been tested by pattern Visual Evoked Potential (VEP) under chloral 
      hydrate sedation. Five of the 11 patients with compensatory head posturing were 
      found to be amblyopic, three moderately so and two severely affected. The four 
      patients without compensatory head posturing were amblyopic. It is our hypothesis 
      that compensatory head posturing allows peripheral fusion even when significant 
      amblyopia is present. Additionally, the clinical sign of a compensatory head turn 
      to maintain binocular vision does not rule out the presence of significant 
      amblyopia.
