PURPOSE OF REVIEW: There are currently various options available for glaucoma treatment procedures ranging from laser to penetrating to nonpenetrating surgeries. Innovations in glaucoma surgical therapeutics include features such as external application, focused tissue effects, and minimal manipulation as these factors all help lower the risk of side-effects in addition to increasing the success rate of the treatment. Traditional diode laser transscleral cyclophotocoagulation (TSCPC) is invasive and destructive...

Myopia is not a simple refractive error, but an eyesight-threatening disease. There is a high prevalence of myopia, 80% to 90%, in young adults in East Asia; myopia has become the leading cause of blindness in this area. As the myopic population increases globally, the severity of its impact is predicted. Approximately one fifth of the myopic population has high myopia (≥-6 diopters), which results in irreversible vision loss such as retinal detachment, choroidal neovascularization, cataracts, glaucoma, and macular atrophy...

Risk reduction and the attainment of good outcomes in contemporary cataract surgery depend in part on patient compliance with a postoperative regimen of topical eye drops. Topical drops are expensive and challenging to instill properly for patients. The consequences of noncompliance or poor compliance can be significant for the patient (in the case of a complication) and for society (in the case of development of antibiotic resistance). For all of these reasons, new approaches that reduce the need for topical therapy are beginning to emerge, including intracameral injection, sustained or slow-release drug delivery mechanisms, and the recently introduced "Dropless cataract surgery," which involves intravitreal injection of single-use, compounded combination of antibiotics and corticosteroids...

Infectious endophthalmitis is an important cause of vision loss worldwide. This entity most often occurs as a complication of intraocular surgery especially following cataract surgery or intravitreal injection. Endophthalmitis is regarded as a serious complication following ocular surgery and the final visual outcome is fundamentally contingent on timely recognition and intervention. Intravitreal and oral antibiotics in combination with pars plana vitrectomy or vitreous aspiration remain the mainstay in the management of endophthalmitis...

An 18-year-old boy with an obsessive-compulsive disorder of eye rubbing presented with forme fruste keratoconus (KC) and posterior subcapsular cataracts. After evaluation, he underwent phacoemulsification in his left eye with intraocular lens implantation. The aggressive eye rubbing, however, aggravated the rapid progression to established KC, and further acute corneal hydrops within 3 months. Within the next 3 months, the eye rubbing precipitated rhegmatogenous retinal detachments (RDs) in both eyes. Furthermore, after undergoing a combined cataract and RD surgery with belt buckling and silicone oil endotamponade in his right eye, the repeated eye rubbing caused extrusion of the implanted silicone oil into the subconjunctival space and within the corneal stroma...

BACKGROUND: Post-operative endophthalmitis is a serious complication of intraocular surgery which may present acutely or chronically. Chronic post-operative endophthalmitis is characterized by decreased visual acuity, mild pain, and low-grade uveitis several weeks or months after intraocular surgery which may be responsive to corticosteroids, but recur upon tapering. Low virulence organisms such as Propionibacterium acnes are the most common culprit organisms, and treatment most often consists of both intravitreal antibiotic injections and surgery...

We reported a new complication after dexamethasone implant injection. The patient was treated by dexamethasone implant injection for diabetic macular edema. After injection, we report an implant stucked in Berger's space behind the crystalline lens capsule in the visual axis. This situation resolved after cataract surgery and the implant moved to a less inconvenient localization.

BACKGROUND: Pseudophakic cystoid macular edema (PCME) is a common complication of cataract surgery. We report the management of a case presenting with PCME in his left eye complicated by a full-thickness macular hole (MH). Four weeks after a cataract surgery on his left eye, a 75-year-old man presented with a vision loss on the same eye (best-corrected visual acuity: 20/64). A PCME complicated by a full-thickness MH was diagnosed. After oral acetazolamide treatment, the PCME completely regressed and the full-thickness MH closed after medical treatment...

Positive vitreous pressure (PVP) occurs during anterior segment intraocular surgery associated with acute hypotony and is characterized by forward displacement of the lens-iris diaphragm with shallowing of the anterior chamber resistant to reformation, repeated iris prolapse, and, in severe cases, zonular rupture and vitreous or lens prolapse that can lead to a cascade of intraoperative complications. PVP is particularly common during penetrating keratoplasty (PK), conventional nuclear expression cataract extraction, and repair of anterior open globe injury...
