Teleophthalmology through handheld mobile devices: a pilot study in rural Nepal.

Background: To compare screening referral recommendations made by remotely located ophthalmic technicians with those of an ophthalmologist examining digital photos obtained by a portable ophthalmic camera system powered by an iOS handheld mobile device (iPod Touch).

Methods: Dilated screening eye exams were performed by ophthalmic technicians in four remote districts of Nepal. Anterior and posterior segment photographs captured with a Paxos Scope ophthalmic camera system attached to an iPod Touch 6 generation device were uploaded to a secure cloud database for review by an ophthalmologist in Kathmandu.

Effect of Graft Attachment Status and Intraocular Pressure on Descemet Stripping Automated Endothelial Keratoplasty Outcomes in the Cornea Preservation Time Study.

Purpose: To examine the association of donor, recipient, and operative factors on graft dislocation after Descemet stripping automated endothelial keratoplasty (DSAEK) in the Cornea Preservation Time Study (CPTS) as well as the effects of graft dislocation and elevated IOP on graft success and endothelial cell density (ECD) 3 years postoperatively.

Design: Cohort study within a multi-center, double-masked, randomized clinical trial.

Methods: 1090 individuals (1330 study eyes), median age 70 years, undergoing DSAEK for Fuchs endothelial corneal dystrophy (94% of eyes) or pseudophakic or aphakic corneal edema (6% of eyes).

Postoperative Endothelial Cell Density Is Associated with Late Endothelial Graft Failure after Descemet Stripping Automated Endothelial Keratoplasty.

Purpose: To determine whether preoperative endothelial cell density (ECD) and postoperative ECD after Descemet stripping automated endothelial keratoplasty (DSAEK) are associated with late endothelial graft failure (LEGF) in the Cornea Preservation Time Study (CPTS).

Design: Cohort study within a multicenter, randomized clinical trial.

Participants: A total of 1007 individuals (1223 study eyes), mean age 70 years, undergoing DSAEK for Fuchs' dystrophy (94% of eyes) or pseudophakic or aphakic corneal edema (PACE) (6% of eyes) and followed for up to 5 years.

The individual and household impacts of cataract surgery on older blind adults in ethiopia.

Purpose: To comprehensively measure the impacts of cataract surgery on patients' activities and mental and physical health, caregivers' well-being, and household incomes in a resource-poor setting Methods: One thousand two hundred thirty-four bilaterally blind older adults in Amhara region, Ethiopia, were interviewed at baseline and 1030 (83%) re-interviewed at follow-up 1 year later. Six hundred ninety three (45%) at baseline were diagnosed with cataracts and offered free surgery, of which 484 (73%) were operated. Difference-in-difference was used to estimate impacts of surgery, using surgery-ineligible, mostly non-cataract blind as controls.

Clinical Application of a Smartphone-Based Ophthalmic Camera adapter in Under-Resourced Settings in Nepal.

Background: The ability to obtain high quality ocular images utilizing smartphone technology is of special interest in under-resourced parts of the world where traditional ocular imaging devices are cost-prohibitive, difficult to transport, and require a trained technician for operation.

Purpose: The purpose of this study was to explore potential anterior and posterior segment ocular imaging use cases for a smartphone-based ophthalmic camera adapter (Paxos Scope, Digisight Technologies, San Francisco, CA, USA) in under-resourced settings in Nepal.

Methods: From September to November of 2015 we utilized the Paxos Scope smartphone camera adapter coupled with an iPhone 5 to explore anterior and posterior segment clinical applications for this mobile technology.

Blindness, cataract surgery and mortality in Ethiopia.

Purpose: To examine the relationships between blindness, the intervention of cataract surgery and all-cause mortality in a rural Ethiopian population.

Design: Population-based, interventional prospective study.

Methods: Community-based detection methods identified blind Ethiopian persons from two selected kebeles in Amhara region, Ethiopia.

Turning the tide of corneal blindness.

Corneal diseases represent the second leading cause of blindness in most developing world countries. Worldwide, major investments in public health infrastructure and primary eye care services have built a strong foundation for preventing future corneal blindness. However, there are an estimated 4.

Influence of intraoperative epithelial defects on outcomes in LASIK for myopia.

Purpose: To evaluate whether intraoperative epithelial defects have an adverse effect on achieving desired refractive outcomes following laser in situ keratomileusis (LASIK) for myopia.

Design: Observational retrospective case control study.

Methods: Thirty eyes that had intraoperative epithelial defects on the LASIK flap were compared with 60 randomly selected control eyes, matched for age, preoperative spherical equivalent, and preoperative cylinder, that had no intraoperative epithelial defects.

Transient impaired vision, external ophthalmoplegia, and internal ophthalmoplegia after blepharoplasty under local anesthesia.

Purpose: To report a case of transient bilateral vision impairment with external ophthalmoplegia and internal ophthalmoplegia after blepharoplasty under local anesthesia.

Design: Interventional case report.

Methods: A 70-year-old man underwent bilateral upper blepharoplasty under local anesthesia.
