Interventional case series. We measured change in iris profile with accommodation in 92 eyes of 92 patients with pigmentary glaucoma. Mean age was 42 years. Mean change in posterior iris excursion from nonaccommodated to accommodated state was 144.5 μ m. (P < .001). Age was plotted against iris excursion with an estimated least- squares regression line. The estimated Pearson correlation coefficient was- 0.60, (P< .001). Patients younger than 42 years of age had a mean change in excursion of 209.2 μ m compared with 79.8 μ m for those patients older than 42 years. (P< .001) This study found that there is a significant increase in posterior iris bowing in the accommodated state. Increasing age is associated with decreased posterior iris deviation. These findings add evidence to the theory of accommodation- induced reverse pupillary block in pigmentary glaucoma.展开更多

Noncomparative, interventional, prospective case series. Twenty- nine eyelids of 29 consecutive patients operated using the modified Hughes flap and full- thickness skin graft for lower eyelid reconstruction after Mohs micrographic surgery, over a 4- year period. In all patients, the pedicle of the Hughes flap was divided 1 week after the primary operation. Postoperative lower eyelid flap viability and lower eyelid contour complications. Twenty- nine eyelids of 29 patients (mean age: 69± 11 years) were operated using the modified Hughes flap. The mean follow- up period was 14± 6 months (range: 6- 23). There were no cases of lower eyelid retraction, flap ischemia, or necrosis after division. Postoperative complications included lower eyelid margin erythema in 2 patients (6.9% ), upper eyelid lash ptosis in 3 patients (10.3% ), and upper eyelid lateral retraction in 1 patient (3.4% ). Early division of the tarsoconjunctival pedicle of a modified Hughes flap at 1 week does not compromise the viability of the reconstructed lower eyelid and results in a good functional and cosmetic outcome.展开更多
