Stem Cell-Based RPE Therapy for Retinal Diseases: Engineering 3D Tissues Amenable for Regenerative Medicine.
Authors: Ben M'Barek K, Habeler W, Monville C Abstract Recent clinical trials based on human pluripotent stem cell-derived retinal pigment epithelium cells (hPSC-RPE cells) were clearly a success regarding safety outcomes. However the delivery strategy of a cell suspension, while being a smart implementation of a cell therapy, might not be sufficient to achieve the best results. More complex reconstructed tissue formulations are required, both to improve functionality and to target pathological conditions with altered Bruch's membrane like age-related macular degeneration (AMD). Herein, we describe the various opti...

Incidence of unexpected peripheral retinal findings on dilated examination 1  month after cataract surgery: Results in the Perioperative Care for Intraocular Lens Study
Cataract extraction is the most common surgery performed in the United States, with approximately 3 million cases performed annually.1,2 Thus, efforts to streamline postoperative care are useful for patients and providers. Many ophthalmologists routinely perform a dilated examination at the 1-month postoperative visit. However, the 2016 American Academy of Ophthalmology Preferred Practice Pattern3 states that in the absence of symptoms or surgical complications, no study has shown that a dilated examination is necessary.

Thermo-responsive hydrogel as an anti-VEGF drug-delivery system to inhibit retinal angiogenesis in Rex rabbits.
CONCLUSIONS: Bevacizumab released from mPEG-PLGA-BOX (bevacizumab) solution suppressed angiogenesis, and mPEG-PLGA-BOX can be considered as a novel thermo-responsive hydrogel with potential as a gelling carrier for extended bevacizumab drug release to treat intraocular neovascular diseases.

PERSPECTIVES Small Heat Shock Proteins, Amyloid Fibrils, and Nicotine Stimulate a Common Immune Suppressive Pathway with Implications for Future Therapies
The α7 nicotinic acetylcholine receptor (α7nAChR) is central to the anti-inflammatory function of the vagus nerve in a physiological mechanism termed the inflammatory reflex. Studies on the inflammatory reflex have been instrumental for the current development of the field of bioelectronic medicine. An independent investigation of the biological role of αB-crystallin (HspB5), the most abundant gene transcript present in active multiple sclerosis lesions in human brains, also led to α7nAChR. Induction of experimental autoimmune encephalomyelitis (EAE) in HspB5–/– mice results in greater p...

Addressing unmet needs in diabetic retinopathy.
Abstract Diabetic retinopathy (DR), the primary retinal vascular complication of diabetes mellitus, is a progressive disease and a major cause of impaired vision and blindness, especially among individuals who are of working age. Early detection and treatment of DR can prevent 50% to 70% of its associated blindness. However, fewer than half of all US adults with diabetes adhere to guideline-recommended eye-screening schedules. Patients with DR typically have no symptoms in the early stage of the disease and may not seek medical evaluation until DR advances and results in vision impairment. These delays in diagnosi...

Screening for Diabetic Retinopathy with a Nonmydriatic Ultra-Wide-Field Retina Camera by Family Medicine Physicians
Conclusion: To improve early detection of DR new screening methods should be considered. FM physicians were able to accurately identify DR on postlecture images but were not as accurate when evaluating images taken from patients in the FM clinic. Patients found the screening process to be easy and efficient. This study was limited by the small sample size, particularly the limited number of DR cases. Future studies that include cases with a wide variation of DR severity are needed to determine the accuracy of FM physicians at detecting DR in a clinical setting.

How Good is Photoscreening For Young Children ’ s Vision Problems?
This study showed that not only was smartphone photoscreening feasible, but was quite good at screening for potential vision problems. Smartphone photoscreening has the advantages of being more ubiquitously available and thus children in almost any location can be screened. A study of photoscreening using a handheld digital photoscreener in primary care offices validated the technology showing an overall referral rate of 10% to an ophthalmologist with suspected astigmatism, anisometropia and strabismus being the most common reasons. The overall positive predictive rate was 0.60. “…[O]ver 60% of children referre...

What Causes Free Peritoneal Fluid?
Discussion Peritoneal fluid is normal. It decreases the friction of the peritoneum covering abdominal and pelvic organs and helps to protect them and allow their movement. A normal amount of peritoneal fluid is expected on radiological evaluation. Increased peritoneal fluid is a continuum and is concerning as a wide variety of pathological causes are associated with it such as abdominal trauma and appendicitis. At the far end of the scale is ascites that is the accumulation of free fluid more than 25 ml. It is usually associated with abdominal distension but fluid must accumulate before distension can occur and therefore i...

Teleophthalmology as a model for detecting ocular diseases in tribal areas of a North West state in India
Conclusions: In the present situation, where trained workforce is unavailable in these areas, teleophthamology is an appropriate tool by which a number of eye diseases can be detected at early stages. Most of them can be treated in these early stages by lifestyle modification and medical management.
