The transmission achieved a full range of ocular ductions and with grossly undetectable latency. Lack of iris and sclera color and detail, as well as constraints in luminosity, dimensionality and image stability limited the real eye appearance. Yet, the digitally rendered eye moved in the same amplitude and velocity as the native, tracked eye.
Real-time image processing using CNNs coupled to microcameras and a miniscreen DPE may offer improvements in amplitude and velocity of apparent prosthetic eye movement. These developments, along with ocular image precision, may offer a next-generation eye prosthesis.

To develop a vision-targeted health-related quality-of-life instrument for patients with glaucoma who are candidates for minimally invasive glaucoma surgery (MIGS).
Development of a health-related quality-of-life instrument.
Twelve practicing ophthalmologists and 41 glaucoma patients.
A questionnaire was constructed to assess functional limitations, vision-related symptoms, aesthetics, psychosocial issues, and surgical satisfaction for MIGS candidates. Questions were drafted after a review of the literature and subsequently refined based upon input from 1 physician and 4 patient focus groups. Nineteen cognitive interviews were used to ensure that questions were understandable to respondents.
The focus group identified the following key issues and concerns as being important to glaucoma patients functional limitations (eg, driving), bodily discomfort (eg, stinging from drops), changes in appearance (eg, drooping eyelid), and psychosocial concerns (eg, mental burden associated with a diagnosis of glaut steps include electronic administration to patients selected from the American Academy of Ophthalmology Intelligent Research in Sight (IRIS) registry. An electronic patient-reported outcomes platform will be used to administer the questionnaire before and after MIGS. The questionnaire will improve understanding of how surgical interventions such as MIGS impact vision-targeted health-related quality-of-life in glaucoma patients.
To investigate the outcomes of cataract surgery in patients with active diabetic macular edema (DME) who are receiving active treatment with intravitreal anti-vascular endothelial growth factor (VEGF) injections in the perioperative period.
Retrospective clinical cohort study.
We reviewed all patients who underwent cataract surgery and were receiving intravitreal anti-VEGF injections from January 1, 2012 through December 31, 2017. Thirty-seven eyes underwent cataract surgery and received ≥1 intravitreal anti-VEGF injection for a diagnosis of DME within 6 months before surgery. Outcome measures included the development of subretinal or intraretinal fluid in the 6 months after surgery, timing of injections, number of injections, best-corrected visual acuity, and central subfield thickness.
There was a significant improvement between pre- and postoperative best-corrected visual acuity when comparing all eyes (Ps < .0001) and no significant difference in central subfield thickness before and after surgery (P > .05). There were 30 eyes (81.1%) that had fluid on the preoperative optical coherence tomography scan. Seventeen eyes (45.9%) developed new or worsening postoperative DME. Comparing the eyes that did or did not develop worsening DME, there were no differences in postoperative visual acuities (P > .05). Eyes that did develop new fluid had significant increases in postoperative central subfield thickness at both 1 month (350 vs 320 μm, P=.036) and 6 months (342 vs 305 μm, P=.013).
In a real-world setting, patients with cataracts and actively treated DME may undergo cataract surgery but may see a worsening of DME not immediately affecting the best-corrected visual acuity.

Reporting treatment outcomes of slow coagulation transscleral cyclophotocoagulation (TSCPC) as an initial surgical intervention in pseudophakic patients with glaucoma.
Retrospective case series.
This single academic center study reviewed 74 pseudophakic patients who had a diagnosis of glaucoma and no previous glaucoma surgeries (mean age 82.6 ± 12.5 years; mean follow-up 18.7 ± 9.1 months). The intervention used was slow coagulation continuous wave TSCPC (1250-mW power and 4-second duration). The primary outcome measure was surgical success defined as an intraocular pressure (IOP) of 6-21 mm Hg with a ≥20% reduction from baseline, no reoperation for glaucoma, and no loss of light-perception vision. Secondary outcome measures included glaucoma medication use, visual acuity (VA), and complications.
IOP decreased from 27.5 ± 9.8 mm Hg preoperatively to 16.1 ± 6.3 mm Hg postoperatively (P < .001). The preoperative number of glaucoma medications was 4.1 ± 0.9 and 3.1 ± 1.3 post-TSCPC (P < .001). The cumulative probabilities of success at 1 and 2 years were 60.6 % and 58.5%, respectively. When patients were divided into 2 groups based on their baseline IOP being >21 mm Hg (high group) or ≤21 mm Hg (low group), success rates at 2 years were 64.9% and 45.5%, respectively (P=.144). The mean logarithm of the minimum angle of resolution VA changed from 0.70 ± 0.64 to 1.04 ± 0.87 at the last follow-up visit (P=.01). No serious complications were observed and most of the complications were mild and transient.
