PURPOSE Conjunctival erosion in glaucoma drainage device surgery can be prevented by the use of patch grafts to cover the extraocular portion of the tube. Several materials can be used, among them human preserved fascia lata. METHODS The authors present a case of a failed Ahmed glaucoma valve due to encapsulation of the bleb, in which the fascia lata patch placed to cover the tube was removed...
Exfoliative glaucoma is the most common type of secondary open-angle glaucoma worldwide. It is characterized by high intraocular pressure (IOP) and worse 24-hour IOP characteristics. In order to minimize progression, treatment of exfoliative glaucoma has to provide a low long-term mean IOP and good 24-hour IOP control. To achieve these goals, fixed-dose combination eye drops, argon and selectiv...
Glaucoma was and remains one of the most relevant problems of ophthalmology. The percentage of blindness and low vision as a result of glaucoma remains stable and does not tend to decrease.1 Despite modern advances in drug therapy for glaucoma, in many cases, only laser and surgical treatment makes it possible to achieve a stable normalization of intraocular pressure and stabilize visual functi...
Most glaucoma surgeries involve creating new aqueous outflow pathways with the use of a small surgical instrument. This article reported a microscope-integrated, real-time, high-speed, swept-source optical coherence tomography system (SS-OCT) with a 1310-nm light source for glaucoma surgery. A special mechanism was designed to produce an adjustable system suitable for use in surgery. A two-grap...
BACKGROUND To describe, a yet non-documented complication of GDI surgery (glaucoma drainage incision surgery)--anterior to posterior segment migration of Ahmed Glaucoma Valve (AGV) tube. CASE PRESENTATION We report a young 9 year old boy, diagnosed with refractory glaucoma with Reiger anomaly. History included of poor vision in both eyes, left more than right with glare since childhood. He un...
Abetract. Successful glaucoma filtering surgery is characterized by the passage of aqueous humor from the anterior chamber to the subconjunctival space, which results in the formation of a filtering bleb. Aqueous in the subconjunctival space may then exit by multiple pathways. Bleb failure most often results from fibroblast proliferation and subconjunctival fibrosis. Factors associated with an ...
There is a significant demand for procedures that can effectively treat glaucoma with low risk and good visual outcomes. To fill this void, procedures termed "minimally invasive glaucoma surgery", are gaining in popularity. This review will focus on the safety and efficacy of one such minimally invasive glaucoma surgery procedure, the trabecular micro-bypass stent. This stent is intended to low...
Eighty percent of all visual impairment can be prevented or cured by considering the two leading causes in world, i.e., uncorrected refractive error and cataract. Cataracts cause vision loss owing to clouding lens, with age being greatest risk factor. Cataract surgery greatly improve is highly effective. It most commonly performed developed countries. Uncorrected resolved simply wearing proper ...
Comparison of Changes in Intraocular Pressure and Anterior Chamber Before and After Cataract Surgery
Cataract is the leading cause of blindness worldwide. Fortunately, cataract-induced blindness is reversible by cataract surgery. In addition to reclaiming lost vision, cataract surgery lowers intraocular pressure, but the reason for this remains unclear. Understanding the mechanism behind intraocular pressure reduction following cataract surgery has implication for treating glaucoma, which invo...
Malignant glaucoma, which is characterized by a shallow or flat anterior chamber with high intraocular pressure, can usually be resolved by pars plana vitrectomy with anterior hyaloidectomy. We describe two cases in which malignant glaucoma was refractory to conventional treatment and complete vitrectomy. Case one an 88-year-old woman with pseudoexfoliation glaucoma underwent trabeculotomy and ...
