Diagnostic occlusion test in intermittent exotropia.

Purpose: We sought to determine the ideal length of time to use the diagnostic occlusion test (DOT) in the evaluation of patients with intermittent exotropia.

Methods: Eighty-two consecutive intermittent exotropia patients were prospectively evaluated. After the routine ophthalmic examination, the DOT was applied for 1, 3, and 24 hours.

Effects of different contact lens materials and contact lens-wearing periods on conjunctival cytology in asymptomatic contact lens wearers.

Purpose: To investigate the conjunctival cytologic changes induced by different contact lens materials and contact lens-wearing periods in asymptomatic contact lens wearers.

Methods: Seventy-five patients (150 eyes) who were to wear contact lenses for the first time were evaluated in this study. Forty eyes of 20 soft hydroxyethylmethacrylate (vinyl pyrrolidone copolymer) contact lens wearers, 70 eyes of 35 soft Polymacon contact lens wearers, and 40 eyes of 20 hard gas-permeable contact lens wearers used the lenses on a daily-wear basis.

Corneal bee sting-induced endothelial changes.

Purpose: To report the acute management and clinical findings of a case of corneal bee sting and to report the outcome of corneal endothelial cell analysis 1 year after trauma.

Methods: Clinical findings, anterior segment photographs, corneal endothelial images, and medical treatment of a case of right corneal bee sting are presented. Right and left central corneal endothelial cell analysis was performed by noncontact specular microscopy.

Two cases of Stenotrophomonas maltophilia endophthalmitis.

Two cases of Stenotrophomonas maltophilia endophthalmitis, a rare cause of postoperative endophthalmitis, are reported in this study. Both of the patients underwent vitreus tap and intravitreal antibiotic injection. The therapy was augmented with systemic and subconjunctival injections.

Corneal endothelial polymegethism and pleomorphism induced by daily-wear rigid gas-permeable contact lenses.

Purpose: To determine if there are any corneal endothelial cell size and shape changes (and the time course of these changes) in subjects wearing rigid high gas-permeable (RGP) contact lenses for daily wear.

Methods: Ninety-seven eyes of 57 new wearers were fitted with a fluoroperm contact lens material (Persecon92E, oxygen transmissibility (Dk)= 92 x 10(-11)). Prior to lens wear and after 1 week, 1 month, 3 months, 6 months, and 1 year, noncontact endothelial photographs were taken.
