[Correlation analysis of pupil light reflex and visual functions after unilateral ocular contusion].
SUBJECTS AND OBJECTIVE: To measure the quantitative pupil light reflex after unilateral ocular contusion, analyze the correlation of pupil light reflex and other tests of visual function. ⋯ Pupil light reflex amplitude measurement is superior to other pupil measurements for reflection of the changes of visual function after ocular contusion. The correlations of pupil light reflex amplitude and visual acuity, visual field, visual evoked potential are significant in the ocular contusion patient. Pupil light reflex combined with visual evoked potential could elevate the possibility of predicting visual function precisely after ocular contusion.

Comparative Study
[Fresh versus preserved amniotic membrane transplantation for conjunctival surface reconstruction].
To compare the effect of fresh versus preserved amniotic membrane transplantation for conjunctival surface reconstruction after symblepharon lysis and analyze the associated factors. ⋯ Fresh amnion has the same effect as preserved one for conjunctival surface reconstruction. The degree of symblepharon and the surgical environment of the ocular surface in the affected eye before surgery will influence the results of amniotic membrane transplantation for conjunctival surface reconstruction.

To investigate the effect and the best concentration of Tetrandrine (Tet) eye drops in inhibition of the corneal allograft rejection in rat. ⋯ The results indicate that 0.5% Tet eye drops significantly inhibit the corneal allograft rejection in rats without obvious side effects.

Randomized Controlled Trial
[Clinical observation of tramadol on postoperative painment from LASEK].
To evaluate the efficacy and safety of tramadol for controlling post-operative ocular pain from laser assisted subepithelial keratomileusis (LASEK). ⋯ tramadol plays an important role in efficacy and safety for controlling ocular pain and inflammation after LASEK.

To evaluate the indications and effects of continuously wearing the Bausch & Lomb Pure-Vision (PV)Contact Lens. ⋯ treating corneal diseases and ocular surface diseases, as well as corneal protection, corneal healing and pain relief. The lens has increased oxygen transmissibility and good anti-deposit quality, reducing the risk of ocular complications. As a result of these, PV Contact Lens is the ideal bandage therapeutic lens.
