  1. CCT =  central corneal thickness, AL =  axial length, ACD =  anterior chamber depth, LT =  lens thickness, BCVA =  best-corrected visual acuity, logMAR =  logarithm of the minimum angle of resolution, IOP =  intraocular pressure
  2. a Data are presented as means ± standard deviations, and the ranges are listed below. Generalized estimating equations were used to test the differences in age, CCT, AL, BCVA, IOP and follow-up time between nanophthalmic eyes and normal eyes. The χ2 test was used to test the differences in the distributions of sex and eye laterality
  3. b Statistically significant (P < 0.05)
