Off the Cuff: Who the Hell is Dr. Craig Weiss, OD?
I think it’s time to declare scam awareness month for optometry. Like many of you, Shannon and I both received unapplied-for Amazon credit cards last year. Her one, me two. I am a naturally suspicious, cynical native NYer, so stuff like this doesn’t phase me. All three breaches were caught and accounts cancelled immediately, with appropriate steps taken to lock down our credit. I still have no idea why anyone would have gone to the trouble of applying for Amazon credit cards for ODs across the country.

Macular Edema After Cataract Surgery in Eyes With and Without Pseudoexfoliation Syndrome | ||||
The purpose of the study was to identify macular edema after cataract surgery in eyes with and without pseudoexfoliation syndrome. The study was a post-hoc analysis of a randomized, double-blind, prospective single-center study. Patients were enrolled between January 2016 and October 2016 as per the national guidelines for the management of cataract in the Department of Ophthalmology, Kymenlaakso Central Hospital, Kotka, Finland. A total of 156 eyes of 149 patients undergoing routine cataract surgery were included. Postoperatively anti-inflammatory medication was either dexamethasone (n=78) or diclofenac (n=78). Spectral-domain optical coherence tomography imaging and laser flare meter measurement of the anterior chamber were conducted before surgery and at the control visit 28 days postoperatively. Baseline variables were comparable between eyes with pseudoexfoliation syndrome (n=32) and those without (n=124), except for intraocular pressure and glaucoma medication. In patients having pseudoexfoliation syndrome, central retinal thickness increase (mean ± standard error of the mean) was 63.3μm ± 35.5μm for dexamethasone and 17.6μm ± 5.8μm for diclofenac, compared with 28.9μm ± 8μm and 6.9μm ± 1.3μm in eyes without pseudoexfoliation syndrome, respectively. Aqueous flare at 28 days was 25.8 ± 5.4 pu/ms for patients with pseudoexfoliation syndrome and 18.3 ± 1.8 pu/ms for those without. Best-corrected visual acuity gain and best corrected visual acuity at 28 days were less in patients having pseudoexfoliation syndrome compared to those without (0.39 ± 0.07 vs. 0.59 ± 0.03 decimals; and 0.77 ± 0.06 vs. 0.92 ± 0.03 decimals, respectively). Researchers concluded that eyes with pseudoexfoliation syndrome might be predisposed to an increased aqueous flare and macular edema after cataract surgery. Their findings outlined the need to determine the optimal anti-inflammatory medication after cataract surgery in patients with pseudoexfoliation syndrome. |

Is the Use of Refrigerated Fixed Combination of Dorzolamide 2%-Timolol 0.5% (COSOPT) Associated With Less Ocular Discomfort? A Pilot Study | ||||
In this prospective comparative study, 30 primary open-angle patients and 30 healthy subjects filled in the questionnaire on symptoms (Ocular Surface Disease Index) and subjective stinging feeling scale (one to 10), at the start of study, and 30 days after continuous use of refrigerated fixed combination or placebo eye drops to test the hypothesis that the use of refrigerated fixed combination of dorzolamide 2% plus timolol 0.5% solution (Cosopt) was associated with less ocular discomfort compared with the use of the solution kept at room temperature. Results were processed by applying the methods of descriptive (arithmetical mean, standard deviation) and analytical statistics for evaluation of significance of the difference (Student's t-test).
Ocular discomfort parameters were significantly lower after the use of refrigerated fixed combinations of dorzolamide 2% plus timolol 0.5% solution (t-test, p<0.0001). Breakup time, Schirmer 1 test and intraocular pressure values did not differ. The use of refrigerated fixed combination of dorzolamide 2% plus timolol 0.5% (Cosopt) solution was associated with less ocular discomfort than the use of the same fixed combination at room temperature. |

Structure vs. Function in High Myopia Using Optical Coherence Tomography and Automated Perimetry | ||||
Fifty-eight highly myopic individuals with no posterior abnormalities (mean spherical equivalent refraction ≤ -6.00D and axial length ≥ 26mm) were examined to evaluate the structure-function relationship between retinal thickness using spectral-domain optical coherence tomography and standard automated perimetry in high myopia. All eyes underwent optical coherence tomography with the Spectralis spectral-domain optical coherence tomograph and visual field evaluation with the Humphrey Field Analyzer II-i. Average macular layer thicknesses in each quadrant were calculated in a 6mm × 6mm area centred on the fovea. The visual field was assessed from 17 central locations (10 degrees), approximately the equivalent of the area tested by optical coherence tomography in the macular scan. Linear correlations were made between different macular layer thicknesses and peripapillary retinal nerve layer thickness with their matched visual field sensitivities. Participant ages were 28.2 years ± 6.4 years, mean spherical equivalent refractions were -8.20D ± 1.40D and axial lengths were 26.7mm ± 0.7mm. Investigators found significant positive correlations between layer thickness and corresponding visual field sensitivities as follows: ganglion cell layer in all quadrants, temporal quadrant of the nerve fiber layer with nasal quadrant of the visual field, inferior quadrant of the outer nuclear layer with superior visual field, and temporal-superior peripapillary nerve fiber layer with nasal-inferior visual field. Investigators wrote that the correlation between retinal layer thicknesses and visual field sensitivity could be explained by myopia-related losses due to lateral retinal stretching, but that additional research would be needed to confirm the findings. |
