Objective
To obtain physicians’ “real-world” perspectives on early experiences with triamcinolone acetonide suprachoroidal injection (SCS-TA) for treatment of patients with uveitic macular edema (UME).
Results
Twelve retina/uveitis specialists in the United States were surveyed about SCS-TA injection procedure and patient outcomes. Survey participants administered ≥ 291 SCS-TA injections to 243 patients with UME with various disease characteristics (etiologies, chronicity, and anatomical subtypes). Commonly reported reasons for SCS-TA adoption included potential for lowering the risk of steroid-associated intraocular pressure elevations versus intravitreal injections or implants (100%), potential for longer duration of action versus intravitreal steroid injections or implants (92%), and desire to use a new delivery modality (83%). Nearly all participants (92%) found injection procedure relatively easy post-training, with most (75%) procedurally comfortable after completing 2–5 injections. 58% of participants indicated that their patients gained 2–3 lines of vision by first follow-up visit, and 92% reported having patients who experienced 100–150 μm or greater reduction in central subfield thickness. Overall, 92% of participants were satisfied with SCS-TA treatment outcomes. Findings from this survey of early adopters of SCS-TA indicate that the suprachoroidal injection technique was easy to learn and resulted in favorable patient outcomes consistent with clinical trial data.

This phase 3 trial showed that persons with noninfectious uveitis who received adalimumab were more likely to have serious adverse events and less likely to have ophthalmic inflammation, uveitic flare, or visual impairment than were those who received placebo.
Noninfectious uveitis is a group of vision-threatening diseases that are characterized by intraocular inflammation; it can occur as a syndrome isolated to the eye or in association with a systemic condition. Uveitis has an estimated incidence of 17 to 52 cases per 100,000 person-years

Purpose:
To report the complication of infectious ulcerative keratitis after laser photocoagulation and pars plana vitrectomy (PPV) for retinopathy of prematurity (ROP).
Methods:
A retrospective chart review of infants treated for ROP with plus disease between 2004 and 2013 at University Hospital, Newark, New Jersey.
Results:
Of the 110 eyes (55 patients) that underwent treatment for ROP, 8 (7.27%) eyes were noted to develop infectious ulcerative keratitis in 4 neonates (4 eyes after laser photocoagulation and 4 eyes after PPV). All 8 eyes that developed ulcerative keratitis had a preceding corneal epithelial defect followed by corneal stromal haze. Seven of 8 eyes developed epithelial defect within 8 days of the procedure. All epithelial defects progressed to ulcerative keratitis within 7 days. A total of 10 (9.1%) eyes developed postoperative epithelial defects, and 8 (80%) of these eyes were ultimately diagnosed as having ulcerative keratitis. Four (4.08%) of 98 eyes treated with laser photocoagulation alone developed infective ulcerative keratitis, compared to 4 (33.33%) of 12 eyes treated with PPV. Because keratitis healed, corneal opacification ensued and covered 10% to 90% of the corneal surface area. Five of the 8 eyes had positive culture of corneal scrapings: 2 grew coagulase-negative Of the 110 eyes (55 patients) that underwent treatment for ROP, 8 (7.27%) eyes were noted to develop infectious ulcerative keratitis in 4 neonates (4 eyes after laser photocoagulation and 4 eyes after PPV).

Descemet Stripping Endothelial Keratoplasty in a Patient with Keratoglobus and Chronic Hydrops Secondary to a Spontaneous Descemet Membrane Tear
2013
Purpose. To report the use of Descemet stripping endothelial keratoplasty (DSEK) in a patient with keratoglobus and chronic hydrops. Case Report. We describe a case of a 28-year-old man with bilateral keratoglobus and chronic hydrops in the right eye secondary to spontaneous Descemet membrane tear. The patient presented with finger counting (CF) vision, itching, foreign body sensation, and severe photophobia in the right eye. Peripheral corneal thinning with central corneal protrusion and Descemet membrane tear spanning from 4 to 7 o'clock was noted on slit lamp examination. The right eye cornea was 15 mm in the horizontal diameter. After a 5.5-month loss to follow-up, the patient presented with discomfort, photophobia, decreasing vision, and tearing in the right eye. Vision was 20/60 with pinhole. 360-degree peripheral corneal ectasia with mild neovascularization and hydrops was present. Over the next few months, the patient complained of photophobia and intermittent eye pain. His vision deteriorated to CF, he developed corneal scarring with bullae, and a DSEK was performed. Eight months postoperatively, best-corrected vision improved to 20/30, cornea was clear, and the DSEK graft was stable. Conclusions. Nonresolving hydrops secondary to Descemet membrane tear in a patient with keratoglobus may result in permanent endothelial cell damage and scar formation. This may be successfully treated with DSEK.

Purpose
The purpose of this study is to report a case of
Providencia stuartii
conjunctivitis.
Methods
This study is a retrospective chart review of a patient with persistent conjunctivitis.
Results
We report the first case of
P. stuartii
conjunctivitis. Our patient was an elderly man living in a nursing home who was likely immunocompromised from longstanding diabetes mellitus. A conjunctival swab culture was able to identify the infecting bacteria and its antibiotic susceptibility. The conjunctivitis was successfully treated with vancomycin drops and oral sulfamethoxazole and trimethoprim.
Discussion
P. stuartii
is an increasingly common bacterium found in the urine of immunocompromised nursing home residents with indwelling Foley catheters. While it has rarely been found to cause ocular infections,
P. stuartii
may be suspected in elderly, immunocompromised nursing home residents.

Background
The purpose of this study was to describe comorbidities, healthcare costs, and resource utilization among patients with chronic non-infectious uveitis initiating corticosteroid, immunosuppressants, or biologics.
In this retrospective cohort study, patients with a non-infectious uveitis diagnosis and continuous insurance coverage during a 6-month baseline were selected from a privately insured claims database with 80.7 million enrollees. Index dates were defined as the first prescription/administration of a corticosteroid, immunosuppressant, or biologic between 2003 and 2009. Comorbidities, healthcare costs, and utilization were analyzed in a per-member-per-month (PMPM) framework to account for varying between-patient treatment periods, defined as continuous medication use within the same class. Wilcoxon rank-sum and chi-square tests were used for comparisons of costs and categorical outcomes.
Results
Patients on corticosteroids (
N
= 4,568), immunosuppressants (
N
= 5,466), and biologics (
N
= 1,694) formed the study population. Baseline PMPM inpatient admission rates were 0.029 for patients on corticosteroids, 0.044 for patients on immunosuppressants, and 0.045 for patients on biologics (
p
< 0.001 immunosuppressants or biologics versus corticosteroids); during treatment, PMPM inpatient admissions increased to 0.044 and 0.048 for patients taking corticosteroids and immunosuppressants, respectively, but decreased to 0.024 for patients taking biologics (
p
< 0.001 versus corticosteroids and
p
= 0.003 versus immunosuppressants). Baseline average PMPM costs for patients taking corticosteroids, immunosuppressants, and biologics were US$935, US$1,738, and US$1,439 (
p
< 0.001 between groups), while on-treatment PMPM costs excluding drug costs increased to US$1,129 for patients taking corticosteroids but lowered to US$1,592 for patients taking immunosuppressants, and US$918 for patients taking biologics (
p
< 0.001 versus corticosteroids or immunosuppressants).
Conclusions
There is significant economic burden associated with existing treatments of uveitis. Corticosteroids may be overused as a treatment for uveitis.

Descemet's Membrane Detachment Caused by the Improper Injection of Sodium Hyaluronate
2010
A case of a Descemet's membrane detachment (DMD) caused by the inadvertent intracorneal injection of sodium hyaluronate was presented. This was concluded after chemical analysis of a viscous substance found in a patient's cornea showed to be a breakdown product of sodium hyaluronate. Surgical correction of the detachment included removing the viscous substance and tamponading the detachment with an air bubble. Although other gases such as sulfur hexafluoride (SF6) provide longer means of tamponade, they have increased postoperative risks like glaucoma associated with their use. Air can provide an effective means of tamponade with minimal postoperative risks.

Comparison of Venous Thrombosis Complications in Midlines Versus Peripherally Inserted Central Catheters: Are Midlines the Safer Option?
2019
Catheter-related (CR) thrombosis is a significant complication of midline catheters (MCs) and peripherally inserted central catheters (PICCs). Limited existing data for MCs suggest a favorable complication profile for MCs. To compare incidence of CR thrombosis between MCs and PICCs and to evaluate the impact of quantity of lumens and catheter diameter on CR thrombosis. This was a retrospective comparison spanning 13 months of MCs and PICCs for symptomatic CR thrombosis at an 1100 bed tertiary care academic medical center. Adult patients who had an MC or a PICC placed by the were included. Data were collected using the electronic medical record. Statistical analysis was performed using SAS software. A total of 2577 catheters were included in the analysis with 1094 MCs and 1483 PICCs. One hundred thirty (11.88%) MCs developed CR thrombosis (deep vein thrombosis [DVT] or superficial venous thrombophlebitis [SVT]) as compared to 112 (6.88%) PICCs (odds ratio [OR]: 1.82; P < .0001). Midline catheters had a 53% greater odds of developing CR DVT than PICCs (7.04% MCs and 4.72% PICCs; OR: 1.53; P = .0126). For CR SVT, MCs have a 2.29-fold greater odds of developing CR SVT than PICCs (4.84% MCs and 2.16% PICCs; OR: 2.29; P = .0002). For MCs and PICCs, the incidence of CR thrombosis was 13.50% for double lumen/5F lines and was 6.92% for single lumen/4F lines (OR: 2.10; P = <.0001). Symptomatic CR thrombosis is a serious, life-threatening complication that occurs more frequently in MCs compared to PICCs. Inserters should consider placement of single lumen catheters with the smallest diameter to reduce this risk when a midline is used.

How Often Should Children with Juvenile Idiopathic Arthritis Be Seen by the Ophthalmologist?
2014
Juvenile idiopathic arthritis (JIA) is an autoimmune disease that can affect children of any age. It is also known as juvenile rheumatoid arthritis, juvenile chronic arthritis, or Still's disease. As the name implies, arthritis is the most frequent presenting symptom and clinical feature in patients afflicted with JIA. The eye is the most common extra-articular site of manifestation. In the eyes, JIA patients most commonly present with anterior uveitis. Identifying signs of ocular involvement can be more challenging in pediatric patients compared with adults because the involved eyes generally do not appear red, children usually don't complain of symptoms, and they are more difficult to examine.
