background: the celebrated generalized estimating equations (gee) approach is often used in longitudinal data analysis. while this method behaves robustly against misspecification of the working correlation structure, it has some limitations on efficacy of estimators, goodness-of-fit tests and model selection criteria. the quadratic inference functions (qif) is a new statistical methodology tha...

Cataract surgery considered as one of the most common surgical procedures performed worldwide. It has been suggested to be clinical benefit for both cataract and glaucoma by many studies. Besides removing cataracts restore vision, proved reduce intraocular pressure (IOP) in patients either with or without glaucoma. showed a great efficacy IOP reduction, considering 1st-line management Its effec...

Penetrating corneal transplant (PKP) surgery has been performed for centuries as the procedure of choice to restore vision in cases of advanced corneal disease. However, the last two decades have seen the introduction of lamellar corneal surgery (deep anterior lamellar keratoplasty, DALK; Descemet stripping-automated endothelial keratoplasty, DSAEK; and Descemet membrane endothelial keratoplast...

Surgical treatment for neovascular glaucoma has evolved from cyclodestructive procedures to full-thickness filtration surgery, to trabeculectomy with antifibrosis drugs and glaucoma drainage implant surgery. The choice of a surgical approach may be influenced by several factors, including the stage of the disease. Many surgeons favor drainage implants when the disease is more advanced or when s...

PURPOSE To evaluate the outcome of trabeculotomy combined with sinusotomy for juvenile glaucoma. METHODS We studied 16 patients (25 eyes) (age range, 11-50 years) with juvenile glaucoma for a minimum follow-up period of 1 year. We performed combined trabeculotomy and sinusotomy surgery in 13 juvenile glaucoma patients (18 eyes), and trabeculotomy alone in 6 patients (7 eyes). RESULTS The in...

BACKGROUND To evaluate vision-related quality of life (VR-QOL) following glaucoma filtration surgery. METHODS A total of 103 glaucoma patients scheduled to undergo glaucoma filtration surgery. Prior to and at three months after glaucoma filtration surgery, trabeculectomy or EX-PRESS, all patients completed the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25). A total of 4...

Glaucoma surgery is ripe for innovation. In the last few years, there has been a substantial increase in the number of devices approaching commercialization. While not all that is new is necessarily good, the role of these devices in changing glaucoma surgery is equally important in terms of both success and failure. Trabeculectomy, the most commonly performed incisional filtration surgery for ...

purpose: to evaluate the histopathologic features of trabeculectomy specimens and the results of tra-beculectomy in relation with these features in patients with chronic primary glaucoma. methods: this interventional case series included 30 eyes of 28 patients with primary chronic glaucoma who underwent trabeculectomy between 2004 and 2006. each case was followed for 6 months post-operatively. ...
