PURPOSE: To determine the long-term visual outcomes and risk factors for visual loss in children with primary congenital glaucoma (PCG) who underwent angle surgery over a 21-year period. METHODS: This was a retrospective study of patients who underwent trabeculotomy, trabeculectomy, or combined trabeculotomy-trabeculectomy for PCG. Visual acuity (VA), surgeries, and underlying cause of visual impairment were recorded and compared. Main outcome measures were final best-corrected good VA (20/20 to 20/50), moderate VA (<20/50 to 20/200), or poor VA (<20/200); age at surgery, sex, laterality, type of initial glaucoma surgery, and number of surgeries were recorded...

In clinical practice, Primary Acute Angle-closure Glaucoma (APACG) is a common disease with an increasing incidence rate and blind rate, and has attracted attention of medical researchers. When a patient suffers both primary acute glaucoma and high tension glaucoma, drug therapy can achieve limited efficacy, and operative treatment is necessary on this occasion. This research mainly explored the safety in treating high tension APACG by compound trabeculectomy, and observed the clinical treatment effect and incident rate of postoperative complications after compound trabeculectomy...

Patients with bleb leakage, dehiscence, or infection after trabeculectomy need urgent bleb salvaging to prevent vision loss. Patients who have undergone a glaucoma drainage device surgery may have tube erosion, which is yet another devastating and outcome-compromising complication. The bleb or the tube in such cases needs to be patched by a biologic tissue, which is roofed by the conjunctiva and acts as a barrier against external infections. Sclera, pericardium, cornea, and dura mater are the commonly used patch graft materials...

Trabeculectomy surgery is the current standard of care in glaucoma for achieving a low target intraocular pressure if medical therapy is not adequate. Augmentation of trabeculectomy with antimetabolites brought a revolutionary change in the long-term success rates of trabeculectomy, but along with it came a plethora of complications. There still is a big window for therapeutic innovations on this subject. The foremost target for these innovations is to modulate the wound healing response after glaucoma drainage surgery...

BACKGROUND: China has the largest burden of primary angle-closure glaucoma (PACG) worldwide. The mechanism of the angle closure is complex and includes pupillary block and non-pupillary block. Currently, opinion is that laser peripheral iridotomy (LPI) alone is not sufficient to prevent disease progression. Laser peripheral iridoplasty (LPIP) is an alternative and effective way of widening the angle recess in eyes that are affected by primary angle closure (PAC). However, it is not known if greater benefit would be achieved using LPI plus LPIP for PAC with multiple mechanisms (MAC)...
