A 60-year-old man developed a rubbery thickening and erythema of his left lateral upper and lower eyelids and lateral canthus over several months. He was treated for an extended period of time for blepharitis and chalazia. Incisional biopsy eventually disclosed microscopically a hypercellular lymphoid population sparing the epidermis that surrounded adnexal structures and infiltrated between orbicularis muscle fibers. Immunohistochemically, the lesion was found to be composed of neoplastic, kappa-restricted B cells with an equal number of reactive T cells and small reactive follicles. The diagnosis was a primary cutaneous extranodal marginal zone B-cell lymphoma of the eyelid skin (EMZL). We review the distinguishing clinical, histopathologic, and immunohistochemical features of cutaneous EMZL and contrast those with EMZL of other ocular adnexal sites. Also offered is a differential diagnosis of cutaneous lymphomas of the eyelid skin, which are predominately T-cell lesions.

Chan K, Deng L, Weissberg E. Detection of Strabismus by Non-Health Care Professionals in an Ethnically Diverse Set of Images.. JAMA Ophthalmol. 2016;134(1):30–6.

IMPORTANCE: Understanding the criteria for when strabismus becomes detectable by non-health care professionals could influence the goals for determining the success of surgical intervention and how patients with such misalignments are counseled. OBJECTIVE: To examine the magnitude at which strabismus is detectable by lay observers in an ethnically diverse set of images. DESIGN, SETTING, AND PARTICIPANTS: Photographs of 12 ethnically diverse models (black, white, and Asian) were simulated to have strabismus from esotropia of 21 prism diopters (∆) to exotropia of 21∆. From July 1, 2007, to October, 1, 2008, images were presented to 120 non-health care professionals aged 21 years or older from the general community in Boston, Massachusetts, who were asked whether strabismus was present. Analysis was conducted from November 1, 2008, to March 31, 2009. MAIN OUTCOMES AND MEASURES: The threshold angle for detecting strabismus to enable 70% of lay observers to make a positive determination whether strabismus is present. RESULTS: In white and black models, the threshold allowing a 70% positive detection rate was higher for esotropia than for exotropia (P < .001 for both). For white models, the threshold was 23.2∆ (95% CI, 21.0∆ to 26.5∆) for esotropia and 13.5∆ (95% CI, 12.5∆ to 14.6∆) for exotropia. For black models, the threshold was 20.8∆ (95% CI, 19.2∆ to 22.2∆) for esotropia and 16.3∆ (95% CI, 15.5∆ to 17.2∆) for exotropia. Asian models showed an opposite trend, with the threshold allowing a 70% positive detection rate for esotropia (14.3∆; 95% CI, 13.2∆ to 15.7∆) being lower than that for exotropia (20.9∆; 95% CI, 18.0∆ to 24.6∆) (P < .001). CONCLUSIONS AND RELEVANCE: Esotropia was easier for lay observers to detect than exotropia in Asian models, and exotropia was easier to detect than esotropia in white and black models. This information should be considered when managing patients who have concerns about the social significance of their strabismus. Future studies should include diverse individuals and make an effort to account for individual factors that may alter the perception of strabismus.

Shields P, Jakobiec F, Stagner A, Yoon M. Spitz nevus arising in the eyelid of a teenager.. Surv Ophthalmol. 2016;61(2):228–35.

A 16-year-old boy developed over a 2-month interval a lightly pigmented left upper eyelid lesion measuring 1.5 mm in greatest diameter that, when excised, microscopically was hypercellular and composed almost exclusively of nonpigmented epithelioid cells that created florid, large intraepidermal junctional nests and sheets and nests of subepidermal cells. The diagnosis was a Spitz nevus. HMB-45, MART-1, and microphthalmia-associated transcription factor were all positive and established the melanocytic nature of the benign tumor. The Ki-67 proliferation index (5%) and 2 mitoses/mm(2) were both low; p16 protein was immunohistochemically identified in the nevoid cells. We review the clinical, histopathologic, and other immunohistochemical features of this entity and provide a brief differential diagnosis (including separation from a Spitzoid melanoma). This is only the third eyelid Spitz nevus reported in the literature and is the most fully characterized immunohistochemically. At their present stage of development, contemporary immunohistochemical biomarkers, while providing supplemental information, nonetheless remain less than definitive in terms of reliably distinguishing benign from malignant Spitz lesions.

Jaffe G, Eliott D, Wells J, Prenner J, Papp A, Patel S. A Phase 1 Study of Intravitreous E10030 in Combination with Ranibizumab in Neovascular Age-Related Macular Degeneration.. Ophthalmology. 2016;123(1):78–85.

PURPOSE: To assess the safety and tolerability of E10030 (Fovista; Ophthotech, New York, NY), a platelet-derived growth factor (PDGF) antagonist, when administered in combination with an anti-vascular endothelial growth factor (VEGF) agent, ranibizumab (Lucentis; Genentech, South San Francisco, CA) 0.5 mg, by intravitreal injection in participants with neovascular age-related macular degeneration (NVAMD). DESIGN: Prospective phase 1 clinical trial. PARTICIPANTS: A total of 23 participants diagnosed with NVAMD and aged 50 years or older were enrolled. METHODS: Part 1 included 15 participants. Three participants received a single intravitreal E10030 (0.03 mg) injection and were subsequently given intravitreal ranibizumab (0.5 mg) injections at weeks 2, 6, and 10. Twelve participants (3 per group) received E10030 (0.03, 0.3, 1.5, or 3.0 mg) in combination with ranibizumab (0.5 mg) at day 0, month 1, and month 2 in an ascending manner. In Part 2 (8 participants), E10030 (0.3, 1.5, or 3.0 mg) in combination with ranibizumab (0.5 mg) was injected at day 0, month 1, and month 2. MAIN OUTCOME MEASURES: Safety at week 12 was the primary outcome and included assessment of vital signs, laboratory tests, and serial eye examinations. Other safety metrics included assessment through week 24 of Early Treatment of Diabetic Retinopathy Study (ETDRS) visual acuity (VA) and biomarker changes evaluated by optical coherence tomography (OCT) and fluorescein angiography (FA). RESULTS: All doses of intravitreal E10030 administered in combination with ranibizumab were well tolerated. No dose-limiting toxicities or relevant safety events were noted at any dose level during the study. Investigators did not report adverse events related to E10030 or ranibizumab. Mean VA change was a gain of 14 letters, and 59% of participants gained ≥15 letters from baseline at week 12. On FA at week 12, there was an 85.5% mean reduction from baseline in choroidal neovascularization (CNV) size. On OCT at the week 12 visit, there was a mean decrease in center point thickness and central subfield thickness of 38.9% and 33.7%, respectively. CONCLUSIONS: Intravitreal E10030 administered at doses up to 3 mg in combination with ranibizumab was well tolerated without evidence of systemic or ocular toxicity in participants with NVAMD. The changes in both mean VA and imaging biomarkers suggest a favorable short-term safety profile for the combination therapy of E10030 and ranibizumab.

Sjögren's syndrome is an autoimmune disease associated with inflammation of exocrine glands with clinical manifestations of dry eye and dry mouth. Dry eye in this disease involves inflammation of the ocular surface tissues - cornea and conjunctiva. While systemic blockade of adhesion molecules has been used to treat autoimmune diseases, the purpose of this study was to determine the therapeutic efficacy of topical application of an integrin α4 adhesion molecule antagonist in a mouse model of dry eye associated with Sjögren's syndrome. To assess this spontaneously developed ocular surface inflammation related to Sjögren's syndrome in TSP-1null mice (12 wks) was evaluated. Mice were treated with topical formulations containing 0.1% dexamethasone or 30 mg/ml GW559090 or vehicle control. Corneal fluorescein staining and conjunctival goblet cell density were assessed. Real-time PCR analysis was performed to assess expression of the inflammatory marker IL-1β in the cornea and Tbet and RORγt in the draining lymph nodes. Ocular surface inflammation was detectable in TSP-1null mice (≥12 wk old), which resulted in increased corneal fluorescein staining indicative of corneal barrier disruption and reduced conjunctival goblet cell density. These changes were accompanied by increased corneal expression of IL-1β as compared to WT controls and an altered balance of Th1 (Tbet) and Th17 (RORγt) markers in the draining lymph nodes. Topically applied dexamethasone and GW559090 significantly reduced corneal fluorescein staining compared to vehicle treatment (p = 0.023 and p < 0.001, respectively). This improved corneal barrier integrity upon adhesion molecule blockade was consistent with significantly reduced corneal expression of pro-inflammatory IL-1β compared to vehicle treated groups (p < 0.05 for both treatments). Significant improvement in goblet cell density was also noted in mice treated with 0.1% dexamethasone and GW559090 (p < 0.05 for both). We conclude that similar to topical dexamethasone, topically administered GW559090 successfully improved corneal barrier integrity and inflammation in an established ocular surface disease associated with Sjögren's syndrome.

DeLoss K, Le HG, Gire A, Chiu G, Jacobs D, Carrasquillo K. PROSE Treatment for Ocular Chronic Graft-Versus-Host Disease as a Clinical Network Expands.. Eye Contact Lens. 2016;42(4):262–6.

BACKGROUND: Keratoconjunctivitis sicca occurs in 40% to 90% of patients with ocular chronic graft-versus-host disease (cGVHD). Ocular symptoms can have profound effects in both the visual function and quality of life of patients with GVHD. We report the impact of prosthetic replacement of the ocular surface ecosystem (PROSE) treatment in patients with cGVHD as a clinical network expands. METHODS: We queried the BostonSight PROSE manufacturing database from January 2002 to December 2011. Patients treated for ocular cGVHD were reported by age, gender, year, and network site where the treatment was undertaken. The baseline and six-month follow-up scores of visual function using a standardized validated instrument, the National Eye Institute Visual Function Questionnaire (NEI VFQ-25), were evaluated for a period in 2006 and again in 2010 after network expansion had occurred. RESULTS: A total of 407 patients with a male:female ratio of 226:181, mean age was 51 years with ocular cGVHD underwent PROSE treatment from January 2002 to December 2011. By 2011, 67% of all cases were treated at network clinics. Baseline characteristics of patients treated throughout the network in 2010 were similar to that of 2006 and 2010 cohorts from the main center. There was a significant improvement of 41 points (P<0.001) in composite NEI VFQ score among patients treated across the network in 2010, similar to the improvement of 30 points (P<0.001) seen among the patients treated at the main center in 2010. There was a trend toward lower baseline self-reported general health status (SRGHS) and VFQ scores among patients treated at network clinics, suggesting that expansion of the network allows treatment of sicker patients (lower general health status) or those more severely affected by ocular cGVHD. CONCLUSIONS: PROSE treatment of ocular cGVHD has increased in the last decade with the establishment of BostonSight network clinics across the United States. Patients treated at network clinics showed similar levels of baseline visual function and SRGHS, and achieved a similar high level of improvement in visual function as those treated at the main center. Patient-reported measures of functional status are useful in evaluating treatment options for patients with cGVHD. PROSE treatment has significant positive impact on the visual function of patients with ocular cGVHD regardless of whether the patient is treated at the main center or at a network site.

Sarker-Nag A, Hutcheon A, Karamichos D. Mitochondrial Profile and Responses to TGF-β Ligands in Keratoconus.. Curr Eye Res. 2016;41(7):900–7.

PURPOSE: Keratoconus (KC) is a complex corneal dystrophy with multifactorial etiology. Previous studies have shown evidence of mitochondrial abnormalities in KC; however, the exact cause of these abnormalities remains unknown. The aim of this study was to identify if transforming growth factor-β (TGF-β) isoforms play a role in the regulation of mitochondrial proteins in human KC cells (HKC). MATERIALS AND METHODS: Human corneal fibroblasts (HCF) and HKC were isolated and cultured for 4 weeks in three different conditions: (a) CONTROL: MEM + 10%FBS, (b) MEM + 10%FBS + TGF-β1 and (c) MEM + 10%FBS + TGF-β3. All samples were processed for mitochondrial damage analysis using real-time PCR. RESULTS: We quantified and analyzed 84 mitochondrial and five housekeeping genes in HCFs and HKCs. Our data showed that when TGF-β1 and/or TGF-β3 were compared with control in HCFs, nine genes were significantly different; however, no genes were significantly regulated by the TGF-β isoforms in HKCs. Significant differences were also seen in seven genes when HFCs were compared with HKCs, in all three conditions. CONCLUSIONS: Overall, our data support the growing consensus that mitochondrial dysfunction is a key player in KC disease. These in vitro data show clear links between mitochondrial function and TGF-β isoforms, with TGF-β1 severely disrupting KC-mitochondrial function, while TGF-β3 maintained it, thus suggesting that TGF-β may play a role in KC-disease treatment.

Chen X, Bleier B, Lefebvre D, Lee NG. Pseudomonas Aeruginosa: A Masquerader in Sino-Orbital Infections.. Ophthal Plast Reconstr Surg. 2016;32(5):374–7.

PURPOSE: To report 2 immunocompromised patients with sino-orbital necrotizing pseudomonas infections and review the literature. METHODS: This is a noncomparative, retrospective case series, and review. The clinical data of 2 patients with histopathologic and microbiologic diagnoses of pseudomonas sinus infections causing orbital cellulitis were obtained from medical records. A retrospective literature review was performed on all reported cases of periorbital pseudomonas infections. RESULTS: One patient with acquired immune deficiency syndrome was noted to have orbital cellulitis with clear visualization of eschar in the middle turbinate on nasal endoscopy. A second patient also had orbital cellulitis with ophthalmoplegia and presence of eschar in the sinus. Both patients had some degree of erosion through the lamina papyracea found on orbital imaging and both had intact vision without optic neuropathy. Pseudomonas infection was confirmed in both cases with permanent histopathology and cultures from conservative sinus debridement. CONCLUSIONS: Pseudomonas sino-orbital infections must be considered in the differential diagnosis in cases of eschar and orbital wall erosion especially when vision is preserved in immunocompromised individuals. This finding obviates the need for radical debridement including orbital exenteration, which can be indicated in cases of invasive fungal disease.

Ma K, Thanos A, Chodosh J, Shah A, Mantagos I. A Novel Technique for Amniotic Membrane Transplantation in Patients with Acute Stevens-Johnson Syndrome.. Ocul Surf. 2016;14(1):31–6.

Cryopreserved amniotic membrane (AM) transplantation is an emerging technique that is becoming the gold standard for the management of acute Stevens-Johnson syndrome (SJS) and its more severe variant, toxic epidermal necrolysis (TEN). We describe a novel surgical technique utilizing a single, large sheet of AM (5 x 10 cm) and a custom-made forniceal ring, which facilitates AM placement. Our technique is easy to use and minimizes suturing and manipulation of ocular tissues, resulting in decreased operative time. This technique may be applied in the management of multiple ocular surface disease processes, including chemical or thermal burns, severe ocular graft versus host disease (GVHD), and other autoimmune diseases.
