Off the Cuff: How to Become a Dry Eye Guru Without Paying Through the Nose
It seems that rarely a week goes by where I don’t hear of yet another dry eye program or protocol. Some of these courses cost hundreds, some thousands of dollars, and all imply that you will be turned into a dry eye expert when they are done. What is especially interesting is that unlike most other clinical specialty areas, where most learning comes through traditional low- or no-cost CE education, there seems to be a lot of money being charged to achieve true dry eye enlightenment.

Microbial Keratitis-Induced Endophthalmitis: Incidence, Symptoms, Therapy, Visual Prognosis and Outcomes | ||||
This retrospective study with 11 patients treated between 2009 and 2014 evaluated symptoms, therapies and outcomes in rare microbial keratitis-induced endophthalmitis. Clinical findings, corneal diseases, history of steroids and trauma, use of contact lenses, number and type of surgical interventions, determination of causative organisms and visual acuity (VA) were evaluated. The incidence of transformation from microbial keratitis to an endophthalmitis was 0.29% (n=11/3773). In 90.9% (n=10/11), there were pre-existent eyelid and corneal problems; in 45.5% (n=5/11), rubeosis iridis with increased intraocular pressure and corneal decompensation; and in 18.2% (n=2/11), ocular trauma. Specimens could be obtained in 10 of 11 samples: 33.3% of those 10 specimens were gram-positive coagulase-negative Staphylococci (n=3/10) or gram-negative rods (n=3/10), and 10.0% were Staphylococcus aureus (n=1/10). In 30% (n=3/10), no pathogens were identifiable. In keratitis-induced endophthalmitis cases, 72.7% (n=8/11) were treated with vitrectomy, 9.1% (n=1/11) with amniotic-membrane transplantation. In 27.3% (n = 3/11), the infected eye had to be enucleated: 18.2% (n=2/11) primarily, 9.1% (n=1/11) secondarily. No patient suffered from sympathetic ophthalmia. The median initial VA was 2.1 logMAR (n=11/11). At one month, median VA was 2 logMAR (n=7/11); after three months, 2 logMAR (n=6/11); and after one year, 2.05 logMAR (n=6/11). The change in VA was not significant. Of all of the cases, 36.4% (n=4/11) resulted in blindness. Researchers concluded that the overall outcome was poor with rare microbial keratitis-induced endophthalmitis. The added that enucleation should be weighed against the risk of local and systemic spread of the infection, prolonged rehabilitation and sympathetic ophthalmia. |

Recurrent Corneal Erosion Caused by Retained Sutures in Blepharoplasty | ||||
Four patients with unilateral recurrent corneal erosion (RCE) were found to have previous blepharoplasty associated with late suture exposure. The clinical courses, characteristics, methods to identify the suture exposure and treatment were presented.
The clinical presentations—including local erosion of upper bulbar conjunctiva, corneal abrasion lines, local corneal epithelial defects with rough border and subepithelial opacity—were noticed in all four patients. RCE symptoms were exaggerated with eye blinking and did not respond to artificial tears treatment. Erosion recurred soon after the removal of therapeutic contact lenses. Individuals underwent blepharoplasty one two 10 years before RCE emerged, and the RCE lasted one to eight months before suture exposure was found. RCE healed within one week after suture removal. Investigators wrote that suture exposure might occur several years after blepharoplasty and could cause RCE. They added that a thorough exploration of the fornix by double eyelid eversion might identify the hidden sutures in such patients. |

A Pilot Study Investigating the Impact of Topical Nasal Steroid Spray in Allergic Rhinitis Patients with Dry Eye | ||||
The aim of this study was to demonstrate the effect of nasal steroid treatment on intraocular pressure and dry eye in allergic rhinitis patients with dry eye. Twenty-nine patients with a diagnosis of allergic rhinitis and dry eye were included. Symptoms and findings of patients before and after nasal steroid therapy were compared.
Researchers found that Ocular Surface Disease Index scores for dry eye symptoms showed significant improvement after nasal steroid treatments. On the Schirmer’s test, no significant change was observed in the right or left eye. For the tear film break-up time, no significant changes were observed in the right or left eye. No significant changes were observed in the right eye or the left eyes in an intraocular pressure test. In this study, symptoms of dry eye with allergic rhinitis were significantly improved with nasal steroid therapy, without affecting the intraocular pressure. |

OcuSoft Reiterates That Zoria Lash Intensifying Serum is Drug-Free In light of recent news reports, OcuSoft reiterated that Zoria Lash Intensifying Serum, part of the Zoria skin care line from OcuSoft, is completely drug-free. Recent reports have shown that prostaglandin or prostaglandin analog-based lash enhancement products, both prescription and over-the-counter, can cause serious side effects to the eyes and surrounding areas. OcuSoft explained in a press release that, presently, there is confusion in the marketplace, due to FDA regulation, about cosmetic ingredients and drug ingredients. The company wrote further that many cosmetic over-the-counter formulas continue to use unapproved prostaglandin analog ingredients such as isopropyl proclostenate, decloro dihydroxy difluoro ethycloprostenolamide and cloprostenol isopropyl ester, which are closely linked chemically to approved prescription drug ingredients, which potentially subject users to possible side effects. However, the company emphasized that non-prescription Zoria Lash Intensifying Serum is a drug-free OTC formula designed to be non-irritating and to deliver noticeable results without potential side effects.
