Patient demographics, unanesthetized Schirmer’s test, serologic markers, and symptoms as measured by the Ocular Surface Disease Index (OSDI) were reviewed. Epithelial thickness from both eyes was measured using anterior segment OCT at the central 3mm and concentric 5mm, 7mm, and 9mm zones for the superior, temporal, inferior, and nasal corneal quadrants. Associations between corneal epithelial thickness with patient demographics, clinical characteristics, and symptoms were evaluated using regression models.Results: Fifteen SjD patients (100% female) were included with a mean age of 58.4 years. Patients with Sjogren’s disease had a significantly thinner superior corneal epithelium compared to the inferior epithelium (mean 47.7mm vs 53.1mm, p = 0.001). The epithelial thickness mean standard deviation (MSD) was significantly inversely correlated with the unanesthetized Schirmer test (r=− 0.39, p = 0.005), suggesting that an overall variability of CET correlates with decreased aqueous tear production. SS-A, SS-B, ANA, and RF positivity were not associated with any measures of CET.Conclusion: This pilot study suggests that there is significant superior versus inferior thinning of corneal epithelium in Sjogren’s patients. There was a significant correlation between variability of corneal epithelial thickness and decreased tear production in Sjogren’s patients. Further larger studies are needed to understand the relationship of CET with objective and subjective measurements of ocular surface disease.Keywords: Sjogren’s disease, corneal epithelial thickness, anterior segment OCT

The purpose of this study was to determine if PRP eye drops improved the symptoms and signs of ocular surface disease.Patients and Methods: A retrospective case series was conducted of patients who were prescribed PRP eye drops. Subjects were excluded if they did not have follow-up, underwent intraocular surgery prior to follow-up, received nerve growth factor treatments, or did not have a baseline examination with photography. Symptoms were assessed using the Ocular Surface Disease Index (OSDI). Patients also underwent a slit lamp exam, ocular surface staining with fluorescein and lissamine green, and Schirmer testing.Results: The charts of 47 patients treated with PRP drops for ocular surface disease were reviewed. Sixty-four eyes of 32 patients were included in the study who had photographs of lissamine green staining taken at baseline and at follow-up. Thirteen patients (28%) had ocular graft-versus-host disease, 16 patients (34%) had Sjögren’s syndrome, and 4 patients (8.5%) had rheumatoid arthritis. There was a statistically significant decrease in OSDI score from baseline to follow-up (39.5 vs 30.8 points, p = 0.02). Among the 64 eyes included, 9 (14%) had an improvement in conjunctival lissamine green staining, while 6 (9%) had an increase in staining at follow-up. Among the 20 eyes with Schirmer testing, there was a borderline significant increase in score from baseline to follow-up (5.9 vs 9.7, p = 0.06). Among the 44 eyes that had corneal fluorescein staining (CFS) reported, 8 (18.2%) had decreased staining and 2 (4.5%) had increased staining at follow-up.Conclusion: Treatment with PRP drops was associated with a significant improvement in symptoms in patients with ocular surface disease. Future larger prospective studies are needed to further evaluate the efficacy of PRP drops for treating ocular surface disease.Keywords: ocular surface disease, cornea, lissamine green, Ocular Surface Disease Index, platelet-rich plasma

We describe clinical findings and treatment of dupilumab-related ocular complications.Patients and Methods: Retrospective study of 19 dupilumab-treated AD patients seen for a new ocular complaint. Primary outcomes were specific ocular exam findings (conjunctival injection, corneal fluorescein staining, blepharitis, meibomian gland dysfunction (MGD)), treatments, and follow-up.Results: Nineteen dupilumab-treated AD patients were included. Median age was 47 years (range 18– 73). Over half were women (11/19) and majority were Caucasian (13/19). Symptom onset occurred at a mean of 99 days (range 23– 520 days) from first dupilumab dose. The most common symptoms were redness (63%), tearing (47%), and pruritus (37%). Most common ocular findings were conjunctival injection (75%) and corneal staining (60%). Blepharitis was seen in about a third (30%), and 25% had MGD. Initially, 10% were observed without treatment, while 15% were treated with artificial tears alone. Other treatments included antihistamine drops (20%) and steroid drops alone (15%). In 40% of patients, a combination of steroids and various other topical eye drops were prescribed. Eighty-four percent (16/19) of patients were seen for follow-up. Steroid drops were required at follow-up in 3 out of 4 patients initially treated with antihistamines alone and in two-thirds of patients initially treated with artificial tears only. Mean follow-up period was 88 days (range 5– 369). Dupilumab was discontinued in 31.5% (6/19) of patients; of those who discontinued, 3 restarted it later.Conclusion: Conjunctival injection was the most frequent dupilumab-related ocular symptom and most common exam finding followed by corneal staining. Most patients initially treated with antihistamine drops or artificial tears alone subsequently required steroid drops to control symptoms. Some patients who discontinued dupilumab restarted the medication after achieving adequate control of ocular symptoms.Keywords: dupilumab, atopic dermatitis, conjunctivitis, cornea, dry eye

Inclusion criteria were assessed at a baseline screening visit and included an Ocular Surface Disease Index (OSDI) score ≥ 13, and a Schirmer with anesthesia ≤ 10 mm/5 min (in at least one eye), with a cotton swab stimulation induced increase of ≥ 4 mm in the same eye. Participants returned for the application visit, where they received intranasal and extranasal applications of the ITN in random sequence, separated by at least 60 min. Schirmer scores were measured in both eyes after each application and compared to baseline values. Generalized linear models were performed to compare the change in Schirmer scores from baseline, and generalized estimating equations were used to account for correlations from repeated measurements in the same eye and measurements from two eyes of the same patient.Results: Fifty-five participants were screened and 35 were enrolled (all female), ranging in age from 31 to 72 years (mean, 57 years). The baseline OSDI score ranged from 14 to 91 (mean, 50.5), and the baseline Schirmer score had a mean (SD) of 6.4 (3.5) ranging from 0 to 20 (mm/5min). Improvement in Schirmer scores was significantly greater for intranasal device application (13.5 mm/5min, 95% CI: 10.4, 16.5) compared to extranasal device application (0.8mm/5min, 95% CI: − 0.9, 2.4) (p< 0.0001). The effects of the intranasal device application were significant regardless of the participant’s baseline Schirmer score and systemic SS medication usage (p< 0.05).Conclusion: Intranasal application of the ITN device significantly increased tear production in a subset of SS patients compared to baseline and was more effective than extranasal application. While production of the ITN device was recently discontinued, our findings suggest that other therapies that neurostimulate the lacrimal function unit may be effective in a subset of SS patients.Keywords: Sjögren syndrome, intranasal tear neurostimulation, tear production

Patients and methods: Fifty patients with diabetes were enrolled. Demographic information and past medical history were recorded. Symptoms were assessed using the ocular surface disease index (OSDI). Tear osmolarity of each eye was measured with the TearLab® Osmolarity System. Results: The majority of the subjects were female (76%), African American (56%), and/or had a diagnosis of type 2 diabetes (82%). The mean ± standard deviation (SD) for age was 54.6±13.4, and maximum tear osmolarity was 304.6±12.7 mOsm/L. Men had higher osmolarity than women (mean ± standard error (SE) 311.8±4.0 mOsm/L versus 302.3±1.9 mOsm/L, P=0.02). Age, race, use of artificial tears, years of diabetes, and hemoglobin A1c did not have a statistically significant association with tear osmolarity. Longer duration of diabetes was associated with lower (less severe) OSDI scores (r=-0.35, P=0.01). Higher tear osmolarity was associated with lower (less severe) OSDI scores (r=-0.29, P=0.04). Conclusion: Approximately half of the diabetic subjects in our study had elevated tear osmolarity, and half of our population also reported symptoms consistent with dry eye disease. However, the two were slightly inversely related in that those with higher osmolarity reported fewer symptoms. Subjects with a longer duration of diabetes also reported fewer dry eye symptoms. Therefore, health care providers should be aware that patients who are most likely to have ocular surface disease, including those with long-standing diabetes, may not experience symptoms and seek care in a timely manner.
