Lowering the limit: reducing the CD4 T-cell threshold for ophthalmic screening in patients with HIV in an ethnically diverse UK population  (access to free full text at end of article)        

Reuters Health (2014) Will Dunham  HIV drugs show promise in treating common eye disease (title links to Medscape write up; if you are not already registered you can either register, or read article below)

WASHINGTON (Reuters) - A class of drugs used for three decades by people infected with the virus that causes AIDS may be effective in treating a leading cause of blindness among the elderly.

HIV drugs called nucleoside reverse transcriptase inhibitors (NRTIs), including AZT and three others, blocked age-related macular degeneration in mice and worked well in experiments involving human retinal cells in the laboratory, researchers said on Thursday.

In HIV-infected people, NRTIs block an enzyme the virus uses to create more copies of itself. The new research shows the drugs also block the activity of a biological pathway responsible for activating inflammatory processes in the body.

It is that previously unrecognized quality that makes NRTIs promising for treating macular degeneration as well as graft-versus-host disease, a rarer ailment that can occur after a stem cell or bone marrow transplant, the researchers said.

University of Kentucky ophthalmologist Dr. Jayakrishna Ambati, who led the study published in the journal Science, said macular generation affects an estimated 50 million people worldwide.

"With the aging of the population, it is projected to affect 200 million people by the year 2020. It is therefore critical that we develop new and improved treatments for this disease, which is growing like an epidemic," Ambati said.

Macular degeneration causes cells to die in the macula, a part of the eye located near the center of the retina that permits vision in fine detail.

The chronic disease has two forms: "dry" and "wet." Several treatments exist for "wet" macular degeneration but only about a third of patients get significant vision improvement. There are no approved treatments for the "dry" form, which is much more common but less severe.

The "wet" type occurs when abnormal blood vessels grow under the macula and leak blood and fluid. The "dry" form occurs when cells in the macula break down.

In the new study, the NRTIs blocked a powerful collection of proteins that can kill cells in the retina, preserving vision in mice.

Researchers are planning for clinical trials in the coming months and it could be known in as soon as two to three years whether the drugs are effective in treating macular degeneration in people, Ambati said.

Because these inexpensive drugs are already approved by the U.S. Food and Drug Administration and have a good safety record, they could be "repurposed" rapidly to treat other illnesses, he added.

Royal College of Ophthalmologists recommends UK regulatory bodies appraise use of bevacizumab for age related macular degeneration potentially saving NHS over £100million a year

NHS Royal College of Ophthalmologists is calling on the regulators find a way to license bevacizumab or NICE to find a way to consider off-label use, for the treatment of AMD and thus save the NHS millions of pounds a year and relieve some of the capacity issues.

In patients with evaporative dry eye, blinking exercises can help decrease partial blinking and improve meibomian gland function and symptoms, according to a new study.

Detecting and quantifying partial blinking and blink training might be important in the overall treatment and management of evaporative dry eye, the investigators report.

David Murakami, MPH, OD, from TearScience Inc. in Morrisville, North Carolina, and Korb Associates in Boston, presented the results at the American Academy of Optometry 2014 Annual Meeting in Denver.

Partial blinking is closely involved in evaporative dry eye, he explained in an interview with Medscape Medical News.

"We are a focused society; we stare at computers, smartphones, and video games, and we are trained not to blink. If you aren't blinking fully, you don't express the oil from the glands," he said.

We have hundreds of patients with evaporative dry eye who are on a blinking program," Dr Murakami reported.

Blink and Brain Training

Dr Murakami presented results on 10 patients diagnosed with partial blinking, symptomatic evaporative dry eye, and reduced gland function. Their mean age was 53 years.

All patients completed a dry eye questionnaire, and habitual blinking behavior was recorded for 20 seconds and analyzed with the LipiView (TearScience Inc.), an ophthalmic imaging device used to measure the tear film lipid layer. In addition, the number of functional lower lid meibomian glands was determined with the Meibomian Gland Evaluator (TearScience Inc.).

Each patient was trained in and performed individualized blinking exercises for at least 8 weeks.

"I tell patients to really pause and deliberately close their eyes," Dr Murakami said. "We are training the lids to be stronger, but we are also retraining the brain to do a full blink." A blinking reminder computer program helped remind the patients to do the exercises.

Patients were assessed before and after the intervention.

The percentage of partial blinks improved significantly with the intervention (70.9% vs 23.5%; P = .001). In addition, symptoms decreased (10.1 vs 6.7; P = .02) and the average number of functional glands increased (4.1 vs 5.9; P = .02).

"Blinking exercises have been a well known antidote for dry eye symptoms due to non or partial blinking for many years," Barry Farkas, OD, an optometrist in private practice in New York City, who was not involved in the study.

"We have employed such assistance for over 35 years. In the old days of mostly rigid contact lenses, those exercises were even more necessary for tear and oxygen flow and exchange," he told Medscape Medical News.

Compliance an Issue

"In today's world, where contact lens materials are all breathable, complete blinking still remains more than helpful in spreading both moisture and nutrients to the entire corneal surface," Dr Farkas explained. "Even for those not wearing lenses, failure to blink completely and regularly can push a marginally unstable tear layer toward a too-short contact time with the cornea and lead to corneal surface breakdown." "The issue with blinking exercises has always been, and remains, finding individuals motivated enough to learn the technique and continue with the process. There are those who might find the treatment not enough of a cure and too much of a nuisance," he said. Dr Murakami said he agrees that compliance is "always going to be an issue." However, education is important. Patients who demonstrate more severe partial blinking and who tend to be very symptomatic are likely to be compliant because they understand the problem, he pointed out. Blinking is "important", said Mina Massaro-Giordano, MD, from the Penn Dry Eye and Ocular Surface Center and the Scheie Eye Institute at the University of Pennsylvania in Philadelphia. She said she has been paying more attention to it. "I was kind of surprised to see the amount of partial blinks my patients have. I do give blinking exercises to some of my patients," she told Medscape Medical News. "What's interesting about this study," Dr Massaro-Giordano said, "is that it shows you can improve the muscles involved in blinking. It's just like any muscle; if you work it, it improves." But she said it is also important consider the eyelids. "Older patients may have lax lids or extropion, so even if they are blinking hard, it may be ineffective because that lower lid is just loose from age, prior surgery, or prior damage," she explained. "You also have to look at the meibum. If you have meibum that is completely socked in and the concretions are really dense and it's very viscous, then you can blink all you want — it's not coming out."

This study was funded by TearScience Inc. Dr Murakami and his coauthors are employees of the company. Dr Farkas and Dr Massaro-Giordano have disclosed no relevant financial relationships. American Academy of Optometry 2014 Annual Meeting: Poster F-039. Presented November 14, 2014

Taylor HR, (2014) Trachoma

Summary Trachoma is the most common infectious cause of blindness. Repeated episodes of infection with Chlamydia trachomatis in childhood lead to severe conjunctival inflammation, scarring, and potentially blinding inturned eyelashes (trichiasis or entropion) in later life. Trachoma occurs in resource-poor areas with inadequate hygiene, where children with unclean faces share infected ocular secretions. Much has been learnt about the epidemiology and pathophysiology of trachoma. Integrated control programmes are implementing the SAFE Strategy: surgery for trichiasis, mass distribution of antibiotics, promotion of facial cleanliness, and environmental improvement. This strategy has successfully eliminated trachoma in several countries and global efforts are underway to eliminate blinding trachoma worldwide by 2020.
