Off the Cuff: Gratitude and Legacies

This weekend I am attending the Rising Stars Reception being held at the Global Specialty Lens Symposium in Las Vegas. This reception is held by the GP Lens Institute to recognize practitioners at the forefront of their specialty.

Dr. Stephanie Woo, who won GPLI's Naomi "Jo" Svochak GP Practitioner of the Year award in 2022, emailed me soon after Dr. Epstein passed, wanting to create a new award in his name. She conceived of and donated proceeds from two Woo Universities to initiate this award in his memory. Many others also donated via Dr. Epstein's memorial webpage or directly via the GPLI website.

Even though he spent the latter part of his career on dry eye and ocular surface disease, Dr. Epstein got his start in specialty lens fitting. It’s very gratifying to see practitioners recognizing his contributions years after it was his primary focus. I extend a big thank you to Dr. Woo for creating the award, Dr. Ed Bennett, president of the GPLI for sponsoring it, and to everyone who donated to keep Dr. Epstein's legacy within our profession alive.

The Use of Progressive Addition Lenses to Improve the Daily Visual Function of Children Receiving Topical Atropine Treatment

These authors presented the changes in visual function when progressive addition lenses (PAL) are added in children using topical atropine as a myopia control therapy. Daily visual complaints and the determination of their near correction were studied. Forty children aged 7 to 12 years were recruited. Distance and near visual acuity, accommodative lag, heterophoria, near point of convergence and stereopsis were examined, and a questionnaire of daily visual complaints was administered.

Significant differences in visual functions were found after the near correction was prescribed. Significant improvements in distance and near visual acuity, lag of accommodation and binocular visual function were observed, and fewer visual complaints were reported at the Harmon distance.

The authors concluded that the use of PAL is helpful for children undergoing topical atropine treatment for myopia control, particularly those receiving medium to high doses. This combination therapy could also be applied to younger children who have a low tolerance to contact lenses, with less risk of ocular adverse effects.

High Load of Demodex in Young Children With Chalazia

This case-control prospective study, conducted at Children’s Hospital of Fudan University between December 2018 and January 2019, investigated the correlation between demodicosis and pediatric chalazia. One hundred one consecutive pediatric patients with chalazia and 42 pediatric patients without chalazia underwent eyelash sampling and Demodex examination using light microscopy, and mite presence and counts were documented.

The Demodex count and prevalence of the chalazia group was much higher than that of the control group. The Demodex count and prevalence of the multiple chalazia subgroup was much higher than that of the single chalazion subgroup. The Demodex count and prevalence of the chalazia with skin erosion subgroup was much higher than that of the without skin erosion subgroup. After adjustment for age and gender, Demodex count, but not presence, was significantly correlated with chalazia.

These results demonstrated that Demodex mites were more prevalent and quantitative in children with chalazia, and children with severe chalazia had higher Demodex prevalence and quantity. High Demodex count rather than presence was associated with chalazia.

Impact of Intraoperative Floppy Iris Syndrome in Cataract Surgery By Phacoemulsification: Analysis of 622 Cases

Small pupil syndromes, including intraoperative floppy iris syndrome (IFIS), increase the risk of complications during cataract surgery if proper surgical planning is not performed. Tamsulosin is associated with a very significant increase in the risk of IFIS, due to the prolonged inactivation of alpha-1 adrenergic receptors in the smooth muscle fiber of the iris. This single-center prospective observational study included 622 eyes of 502 patients, of which 337 were women.

The mean age of the sample was 74.8 years. Sixty-one cases of IFIS (11%) were observed, of which 13 received treatment with Tamsulosin and 1 with Doxazosin. Twenty-three cases of IFIS were observed in female patients. The female:male ratio was approximately 1:3. 19 cases (3%) of severe IFIS were observed, of which 6 received treatment with alpha-antagonists, with no statistically significant correlation. The mean surgical time was 13.80 minutes (standard deviation [SD]: 4.01 minutes) in patients without IFIS and 16.93 min (SD: 4.32 minutes) in patients with IFIS. The relationship between the duration of the surgical procedure in minutes and the presence of IFIS was statistically significant.

The authors concluded that, regardless of the degree of severity, the diagnosis of IFIS lengthened the surgical time in cataract surgery. They wrote, this represents yet another piece of evidence that supports the use of less selective alpha-1 adrenergic antagonist treatments than Tamsulosin or the performance of cataract surgery before starting these treatments.
