Photographs were graded for DR by retina fellows in Mexico via teleophthalmology. Participants were contacted with results and provided referrals when necessary. RESULTS Nearly all (97.6%) participants were aware that diabetes can cause vision loss. One-quarter (24.4%) had undergone an eye examination in the past year. Barriers to care were cost (53.9%) and insurance (45.6%). Most (85.4-91.1%) reported that Spanish-speaking providers and provision of screening in primary care would increase participation in screening. Any DR, vision-threatening DR, or proliferative DR were found in 30.2%, 9.9%, and 5.4% of participants, respectively. Nearly one-fifth (19.5%) received referrals. CONCLUSIONS Screening in Mexican consulates may improve DR detection and treatment among Mexican migrants in the U.S.

Population growth and climate warming are global challenges that threaten not just the health but perhaps the very survival of human beings. These, too, require innovative, "outside-the-box" solutions. At the root of these problems, and their solutions, lies the intimate relationship between where we live (our built environment) and how we live (our behavior). The separation of the disciplines has also been blamed, at least in part, for the failure to recognize the links between the built environment and the health disparities found among communities of color and of low socio-economic status. Correctly designed communities can improve their residents' health by encouraging physical activity, ...

However, there is limited literature focusing on the group’s ophthalmic care engagement. Timely eye examinations and outreach are necessary to reduce visual impairment in this older community. To assess eye care knowledge, attitudes, and practices, we conducted a cross-sectional study surveying Filipino-Americans within the nine San Francisco Bay Area counties. Associations between primary outcomes and sociodemographic factors were analyzed using chi-squared analysis and student’s T-test. In our convenience sample of 256 surveys, a majority of participants are receiving appropriate eye care; those that lacked health and eye insurance, immigrated and are lower income did not receive optimal eye care. Study participants also demonstrated a lack of awareness of eye diseases and risk factors. Our results suggest that culturally sensitive eye health education materials are lacking and should be m...

Research paper thumbnail of Wayfinding Technologies for Older Adults with Visual Impairments: Ideas for Future Directions

Journal of Visual Impairment & Blindness, 2016

The so-called tech boom is affecting all aspects of life from redefining social interaction to physical activity and health outcomes. It should be no surprise that older adults are an important part of the technological revolution since they represent a sizable and growing section of the world's population. As older adults of the present generation expect a longer lifespan, which increasingly includes some experience with visual impairment, technology increases the potential of remaining healthy and active for as long as possible. Technology in the area of wayfinding represents an important element of the overall strategy to achieve this goal. Advances in assistive technologies for wayfinding are increasingly being used to facilitate the mobility, independence, and safety of older adults with visual impairments. Technology does not, however, come without risks. Technology for technology&#39...

Its safety has been proven for long-term use in the treatment of benign essential blepharospasm, hemifacial spasm, and certain types of strabismus. Recent approval from the Federal Drug Administration should make botulinum toxin available for use in a greater number of patients.

Over the previous 18 months, she had been treated with Synthroid and radioactive iodine for Graves' disease. Nonetheless, she noted progressive worsening of her vision over the 2 previous months. Examination revealed severe, bilateral exophthalmos, bilateral optic neuropathy, complete obstruction of her left nasal cavity by a mucocele, and an enlarged, nontender thyroid gland with a left thyroid nodule. Visual acuity was measured at 20/70 in both eyes.

Methods: Retrospective chart review of all patients undergoing transorbital craniotomy through a suprabrow approach at a major medical center from April, 1997 through June, 2000. The effect of surgery on olfactory function was investigated via a phone questionnaire that assessed the sense of smell prior to and following craniotomy. Objective evaluation of olfactory function was evaluated via forced-choice threshold to phenylethyl alcohol and/or odor identification testing. Results: 28 patients completed retrospective phone interviews. Subjectively, 18 patients noted no change in their sense of smell postoperatively, 7 noted a decreased sense of smell and 3 noted improvement. 18 of 28 patients underwent objective testing, which did not agree with patient self-assessment in 4 of 18 instances. 8 of 18 patients tested anosmic and one of 18 tested unilaterally anosmic. No recovery of function was noted at follow-up of at least 8 months after surgery. Postoperative anosmia was more likely in midline or bilateral lesions (p= 0.050). Conclusions: Currently, no human model for the evaluation of therapeutic interventions in the treatment of sensorineural olfactory loss exists. Hyposmia and anosmia are common sequelae of transorbital craniotomy through a suprabrow approach. Such surgical procedures present opportunities for randomized, placebo-controlled human subjects trials studying the effect of medical therapy on the recovery of olfactory function.

With this subspecialization, physicians have often been isolated from colleagues in other disciplines, limiting their opportunities to learn of advances in other subspecialties. Through recent collaborations with neurosurgical colleagues we have developed a combined orbital-neurosurgical approach to orbital tumors, carotid cavernous fistula embolization, and orbital decompression surgery. This approach offers wide surgical exposure and mimimal brain manipulation.

Little attention has been given to problems with community wayfinding, including both individual characteristics (such as reduced lower-body strength, vision impairment, and cognitive deficits) and environmental characteristics (such as broken sidewalks, poor lighting, and heavy automobile traffic) and their potential impact on older adult mobility. Given that improving mobility is a key foundation block for any comprehensive program to enhance the health and well-being of older adults, the chapter explores the potential of current and emerging personal wayfinding technologies to improve wayfinding and enhance mobility. It identifies the relative lack of—and need to build—an evidence base that includes public health outcomes. The RE-AIM (Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance) framework, widely employed in public health to foster effective translation of research to practice, is proposed as a means to assess personal wayfinding technologies. First, questions underlying RE-AIM components are explored for utility in assessing the current status of a given technology. Second, the framework is applied in a manner closer to its original intent to examine the translation and dissemination of a specific technology. Finally, the chapter explores some future directions in this rapidly expanding field.

The anatomic basis, classification, and prevention of lower eyelid retraction are explored, as well as traditional methods of surgical management. Two case reports involving the successful use of acellular human dermis (AHD) for lower eyelid retraction are presented. Lower eyelid retraction is associated with a variety of etiologies, which mandate that the surgical repair be directed toward correction of the anatomic abnormality in each patient. Each surgical procedure and material used in the repair of eyelid retraction is associated with unique advantages and disadvantages. AHD has found multiple uses in oculoplastics, including reconstruction of the middle and posterior lamellae in eyelid retraction. An understanding of the mechanistic basis of lower eyelid retraction and familiarity with newer techniques and materials enable the oculoplastic surgeon to modify and individualize the operative repair, resulting in better surgical outcomes.

AlloDerm (Lifecell Corp., Woodlands, TX) is an acellular dermal graft processed from human donor tissue. The authors sought to assess the efficacy of AlloDerm as a soft tissue replacement in a variety of oculoplastic applications. Design: Retrospective, noncomparative case series. Participants: Twenty-three patients. Methods: Applications were broadly classified as barrier/scaffolding (i.e., primary and secondary implant coverage, lid spacer graft) and volume augmentation (i.e., superior sulcus and other periorbital soft tissue contour defects). Barrier grafts were applied as single sheets. Stacked sheets or rolled grafts were used for augmentation. Collectively, this material was used in 29 cases with 3 to 16 months' follow-up. Main Outcome Measures: Clinical evaluation of outcome and complications. Results: As a soft tissue scaffolding and barrier implant, AlloDerm persisted sufficiently to permit repopulation with native tissue. Rolled/stacked implants demonstrated unpredictable resorption. Upper eyelid grafts seemed to have higher resorption rates than lower eyelid grafts. One case of anophthalmic superior sulcus augmentation required two revision surgeries to provide sufficient volume augmentation. The grafts were well tolerated, with no cases of infection or explanation. Conclusion: Acellular human dermis is an excellent barrier and reconstructive grafting material that provides an alternative to autologous grafts and other alloplastic material, avoids harvesting autologous tissue, possesses excellent handling properties, and is associated with minimal inflammation. Long-term follow-up is required to evaluate persistence.

The implant shape is a modification of a sphere. It has a posterior conical projection paralleling the orbital walls, a superior projection supporting the soft tissues of the upper eyelid sulcus, a flattened anterior surface, and channels for each rectus muscle. Design: The study design was a consecutive case series from the Oculoplastics and Orbital Service of the Massachusetts Eye and Ear Infirmary. Intervention/Participants: A total of 45 patients (average age, 40 years; range, 13-75 years) had placement of a conical implant (39 primary enucleations, 6 secondary implants) with a minimum of 1 year' follow-up (range, 12-36 months). All of the primary enucleations and two of the secondary procedures had the anterior portion of the implant covered with autologous fascia. Four of the secondary implants were covered with pseudocapsule harvested from the explanted primary implant. Prostheses were fit 6 to 10 weeks after surgery. Main Outcome Measures: Postoperative appearance of patients was assessed by qualitative appearance of the superior sulcus and prosthetic motility, and subjectively by patients' satisfaction. Results: A total of 43 patients had minimal or no superior sulcus defect, whereas 2 patients had moderate defects. There were no severe sulcus defects. All patients were satisfied with their appearance and did not seek further surgery to correct any upper sulcus asymmetry. Prosthetic motility with small-angle ductions (<lo') and saccades was good in all cases. There were two cases of conjunctival wound dehiscence. Both occurred within 4 weeks of surgery. One wound dehiscence was sutured, whereas the other healed spontaneously. There were no cases of implant extrusion, migration, or infection. Conclusion: The conical orbital implant provides appropriate reconstitution of orbital volume while minimizing superior sulcus defects with adequate prosthetic motility. Ophthalmology 1998; 105919-925 Recent developments in orbital enucleation implants have been directed toward the use of biocompatible materials, particularly porous implants, and increasing prosthetic motility. Despite these advancements, many patients with Originally

Retrospective, small noncomparative case series. Three patients with angle-closure glaucoma and orbital pseudotumor. The pathophysiology of this entity was investigated using magnetic resonant imaging (MRI) and ultrasound biomicroscopy (UBM). Clinical features, anterior chamber angle configuration, and intraocular pressure. Angle closure from anterior rotation of the ciliary body caused by choroidal effusions secondary to pseudotumor was demonstrated using MRI and UBM. Two of the three cases resolved after treatment for orbital pseudotumor. Idiopathic orbital pseudotumor is a cause of secondary angle-closure glaucoma. The mechanism of angle closure is anterior rotation of the ciliary body secondary to choroidal effusions resulting from the orbital inflammation.

Research paper thumbnail of Choroidal Detachment, Flat Anterior Chamber, and Hypotony as Complications of Neodymium:YAG Laser Cyclophotocoaguiation

Ophthalmology, 1990

Severe hypotony, flat anterior chamber, and serous choroidal detachment after transscleral neodym... more Severe hypotony, flat anterior chamber, and serous choroidal detachment after transscleral neodymium: YAG laser cyclophotocoagulation (Nd:YAG-CPC) for three cases of intractable glaucoma are reported. The three patients had failed previous filtering surgery and were receiving maximal medical therapy. The types of glaucomas treated were two cases of primary open-angle and one chronic-angle closure. The complications were noted between 1 and 2 weeks from the time of treatment. One patient improved spontaneously after 1 week of observation. Another patient required drainage of the choroidal effusion and anterior chamber reformation. The last patient remains under observation with a low intraocular pressure (IOP) and a slowly resolving serous choroidal detachment. Though the incidence of shallow anterior chambers is three cases (0.5%) in this series of 750 Nd:YAG-CPCs, it represents a serious problem that had not been reported previously.

The mechanism of angle closure is anterior rotation of the ciliary body secondary to choroidal effusions resulting from the orbital inflammation.

Severe hypotony, flat anterior chamber, and serous choroidal detachment after transscleral neodym... more Severe hypotony, flat anterior chamber, and serous choroidal detachment after transscleral neodymium: YAG laser cyclophotocoagulation (Nd:YAG-CPC) for three cases of intractable glaucoma are reported. The three patients had failed previous filtering surgery and were receiving maximal medical therapy. The types of glaucomas treated were two cases of primary open-angle and one chronic-angle closure. The complications were noted between 1 and 2 weeks from the time of treatment. One patient improved spontaneously after 1 week of observation. Another patient required drainage of the choroidal effusion and anterior chamber reformation. The last patient remains under observation with a low intraocular pressure (IOP) and a slowly resolving serous choroidal detachment. Though the incidence of shallow anterior chambers is three cases (0.5%) in this series of 750 Nd:YAG-CPCs, it represents a serious problem that had not been reported previously.
