New software (MatchedFlicker, EyeIC) uses time series retinal photographs to convert change into motion and could improve the accuracy and speed of detecting glaucomatous progression.

An investigational compound for the treatment of dry eye disease consisting of a proprietary formulation of sodium hyaluronate ophthalmic solution 0.18% (Vismed, Lantibio Inc.) was shown to be safe and effective in a multicenter phase III trial conducted in the United States.

While ophthalmology has traveled down the road harnessed to organized medicine and thereby exposed to all of the exploding impediments to practice, dentistry has alertly remained aloof to these changes and continues to be viable, productive, and secure.

Healthy vision is vital for success in life and should begin with regular vision screenings during childhood, but the level of inadequate vision care for children in the United States is significant, however. The author addresses ways to address this issue to positively affect high school graduation rates, social and emotional problems, juvenile delinquency, adult literacy problems, incarcerations, and workforce quality and productivity.

A retrospective study analyzed outcomes of 345 consecutive eyes with the proprietary glaucoma minishunt (Ex-PRESS, Optonol) implanted, including 114 eyes having combined cataract surgery. During a mean follow-up of about 2 years, the implant provided effective IOP control whether used alone or in a combination procedure and was associated with few complications.

Results of a survey of 124 ophthalmologists show interest in preservative-free formulations of IOP-lowering medications to preserve ocular surface health. Preservative-free timolol maleate (Timoptic in Ocudose, Aton Pharma) can be a good choice for appropriately selected patients, according to one ophthalmologist.

Implantation of a trabecular micro-bypass (iStent, Glaukos Corp.) in patients with open-angle glaucoma who are undergoing cataract surgery represents an alternative surgical approach that can provide clinically significant reductions in IOP and use of ocular hypotensive medications.

Endocyclophotocoagulation (ECP) can be performed easily in patients with medically controlled glaucoma who are undergoing cataract surgery, to provide additional IOP lowering and reduce medication use. Misunderstanding that ECP is a completely different procedure than transscleral cyclodestruction contributes to under-use of this very safe procedure, according to one ophthalmologist.

Recent literature has identified ocular perfusion pressure as a glaucoma risk factor. Ophthalmologists need to be aware of the growing evidence supporting this theory, according to one expert.

Hyperemia is one of the main reasons why patients with glaucoma do not adhere to or persist with their topical therapeutic regimen. Patients end up switching to another possibly more tolerable medication, and the changing of medications has significant financial implications. Latanoprost has the lowest incidence of hyperemia among the prostaglandin analogs. Patient adherence is crucial in a chronic progressive disease such as glaucoma, where non-adherence can lead to visual loss and decline in quality of life, creating societal health and economic burdens.
