Electronically Monitored Corticosteroid Eye Drop Adherence after Trabeculectomy Compared to Surgical Success
Adherence to frequent postoperative eye drops was high and can be successfully monitored remotely. Surgical success was greater among eyes with nearly ideal adherence and was poorer in older persons and those with more advanced glaucoma.
KEY FINDINGS: Adherence to frequent postoperative eye drops was high and can be successfully monitored remotely. Surgical success was greater among eyes with nearly ideal adherence and was poorer in older persons and those with more advanced glaucoma.
BACKGROUND: Objective of this study was to compare electronically measured adherence with topical corticosteroid (CS) drops with outcomes of glaucoma surgery. This prospective cohort study included eyes undergoing surgery from August 2019 to January 2021 and followed for up to 1 year.
DETAILS: All patients were recruited from the Glaucoma Center of Excellence at the Wilmer Eye Institute, Johns Hopkins. Eligible patients had primary open-angle or angle-closure glaucoma, were aged >=18 years, and underwent trabeculectomy (with or without cataract surgery) or tube-shunt implantation. All patients were recruited from the Glaucoma Center of Excellence at the Wilmer Eye Institute, Johns Hopkins. Eligible patients had primary open-angle or angle-closure glaucoma, were aged >=18 years, and underwent trabeculectomy (with or without cataract surgery) or tube-shunt implantation. Among 90 patients, adherence was 89.7% ± 13.7% overall and 80.9% ± 15.8% during dosing every 2 hours. Target IOP was achieved at the final visit (6 months or 1 year) in 81% (59/73) without reoperation. Eyes with a higher ratio of drops taken versus prescribed were significantly more likely to achieve target IOP at 6 months/1 year (P = 0.05). Total adherence was better in younger persons, eyes with less field loss, and patients of one particular surgeon (P < 0.03). Percent adherence during dosing every 2 hours was higher in eyes with higher target IOP (P = 0.01). No adherence outcome was significantly related to race, sex, bleb morphology, postoperative pain, or postoperative anterior chamber inflammation. Adherence values did not significantly correlate with adherence questionnaire data (predicted mean = 78% ± 17%, actual mean = 91% ± 13% adherent, P < 0.001).

Optic Disc Size and Circumpapillary Retinal Nerve Fiber Layer Thinning in Glaucoma
Larger optic disc size is associated with faster cpRNFL thinning in glaucoma, independent of race. Although previous studies have indicated that Black individuals may be at higher risk for glaucoma development, the present study suggests that race may not be a significant predictor of faster cpRNFL thinning when controlling for optic disc size and other clinical and demographic factors in glaucoma.
KEY FINDINGS: Larger optic disc size is associated with faster cpRNFL thinning in glaucoma, independent of race. Although previous studies have indicated that Black individuals may be at higher risk for glaucoma development, the present study suggests that race may not be a significant predictor of faster cpRNFL thinning when controlling for optic disc size and other clinical and demographic factors in glaucoma.
BACKGROUND: Aim of this study is to investigate the association between optic disc size and circumpapillary retinal nerve fiber layer (cpRNFL) thinning in eyes with preperimetric glaucoma and glaucoma.
DETAILS: A total of 841 eyes (554 primary open angle glaucoma and 287 preperimetric glaucoma) from 553 patients who had at least 4 visits and 2 years of follow-up using OCT participated in the study. Multivariable linear mixed-effects modeling was used to estimate the effect of optic disc size on cpRNFL thinning while controlling for covariates. To eliminate the floor effect, eyes with baseline visual field mean deviation less than -14 dB were excluded. Of the participants, 189 (34.2%) were Black, 338 (61.1%) were White, 20 (3.6%) were Asian, and 6 (1.1%) were another race or ethnicity. Mean follow-up period was 5.3 (95% confidence interval [CI], 5.2-5.5) years, and the mean rate of cpRNFL change was -0.54 (95% CI, -0.61 to 0.47) µm/year. After adjusting for covariates with the Littmann's formula correction, larger optic disc size was associated with faster cpRNFL thinning (-0.03; 95% CI, -0.05 to 0.00) µm/year faster per 0.1 mm2 larger; P = 0.034), while no significant differences were found for race and its interaction with optic disc size.

Risdiplam in Presymptomatic Spinal Muscular Atrophy
Infants up to 6 weeks of age with genetically diagnosed SMA who were treated with risdiplam before the development of clinical signs or symptoms appeared to have better functional and survival outcomes at 12 and 24 months than untreated infants in natural history studies. Larger, controlled studies with longer follow-up are needed to further understand the relative efficacy and safety of presymptomatic treatment of SMA with risdiplam.
KEY FINDINGS: Infants up to 6 weeks of age with genetically diagnosed SMA who were treated with risdiplam before the development of clinical signs or symptoms appeared to have better functional and survival outcomes at 12 and 24 months than untreated infants in natural history studies. Larger, controlled studies with longer follow-up are needed to further understand the relative efficacy and safety of presymptomatic treatment of SMA with risdiplam.
BACKGROUND: Risdiplam, an oral pre–messenger RNA splicing modifier, is an efficacious treatment for persons with symptomatic spinal muscular atrophy (SMA). The safety and efficacy of risdiplam in presymptomatic disease are unclear.
DETAILS: Authors conducted an open-label study of daily oral risdiplam (with the dose adjusted to 0.2 mg per kilogram of body weight) in infants 1 day (birth) to 42 days of age with genetically diagnosed SMA but without strongly suggestive clinical signs or symptoms. The primary outcome, assessed in infants with two SMN2 copies and a baseline ulnar compound muscle action potential (CMAP) amplitude of at least 1.5 mV, was the ability to sit without support at month 12. Natural history studies have shown that the majority of infants with two SMN2 copies who are untreated would have a severe SMA phenotype (type 1), would never sit independently, would receive permanent ventilation and feeding support, or would die by 13 months of age. Secondary outcomes that were assessed over a period of 24 months included survival, ventilatory support, motor milestones, the development of clinically manifested SMA, feeding, and growth. A total of 26 infants with two, three, or four or more copies of SMN2 were enrolled. After 12 months of treatment, 21 infants (81%) could sit unsupported for 30 seconds, 14 (54%) could stand alone, and 11 (42%) could walk alone. A total of 4 of 5 infants (80%; 95% confidence interval, 28 to 100) with two SMN2 copies and a baseline ulnar CMAP amplitude of at least 1.5 mV were able to sit without support for at least 5 seconds. Three infants were withdrawn from the study by a parent or caregiver after the month 12 visit. Of 23 infants who completed 24 months of treatment, all were alive without the use of permanent ventilation or feeding support. Over a period of 24 months, nine treatment-related adverse events were reported in 7 infants; none of these events were serious.

A New Hope for Recurrent Respiratory Papillomatosis: FDA Approves Papzimeos
FDA approved Papzimeos (zopapogene imadenovec-drba), a first-of-its-kind non-replicating adenoviral vector-based immunotherapy for the treatment of adult patients with recurrent respiratory papillomatosis (RRP).
KEY FINDINGS:
BACKGROUND: Recurrent Respiratory Papillomatosis (RRP) is a rare and chronic condition caused by human papillomavirus (HPV) types 6 and 11. The disease leads to the formation of benign tumors in the respiratory tract, most often in the larynx, which can cause significant symptoms like voice changes and difficulty breathing. Historically, the primary treatment for RRP has been repeated surgical removal of the tumors, as there have been no approved medical therapies to address the underlying cause.
DETAILS: The U.S. Food and Drug Administration (FDA) has approved Papzimeos (zopapogene imadenovec-drba), a groundbreaking immunotherapy, for the treatment of adult patients with RRP. This therapy is a non-replicating adenoviral vector that works by stimulating a targeted immune response against the HPV-infected cells. It is administered via a subcutaneous injection and represents the first non-surgical therapeutic option for this rare disease, offering a new approach beyond traditional surgical management.

The approval of Papzimeos was based on data from a single-arm, open-label trial. The study demonstrated that 51.4% of patients who received the treatment achieved a complete response, defined as not needing any further surgical intervention for 12 months following the treatment. The clinical benefits were shown to be durable for most patients over a two-year period and correlated with the development of specific T-cells targeting HPV 6 and 11. The therapy had a favorable safety profile with no serious treatment-related adverse events.
Key information:
- First-of-its-kind Approval: Papzimeos is the first approved medical therapy for RRP.
- Novel Mechanism: It is an immunotherapy that targets the root cause of the disease, HPV-infected cells.
- Approval Pathway: The product received Orphan Drug and Breakthrough Therapy designations and was approved under Priority Review, reflecting the significant unmet medical need for RRP patients.

Distribution of Port-Wine Birthmarks and Glaucoma Outcomes in Sturge-Weber Syndrome
Lower eyelid and choroidal angiomas were associated with glaucoma diagnosis, suggesting a spatial relationship with SWS findings. However, leptomeningeal angiomas were not associated, possibly because these are further from the eye.
KEY FINDINGS: Lower eyelid and choroidal angiomas were associated with glaucoma diagnosis, suggesting a spatial relationship with SWS findings. However, leptomeningeal angiomas were not associated, possibly because these are further from the eye.
BACKGROUND: Objective of the study is to identify which features of Sturge-Weber syndrome (SWS) were most associated with glaucoma onset, severity, and treatment failure at a tertiary care center.
DETAILS: Electronic health records were reviewed for all children with SWS presenting between 2014 and 2020. Examination and imaging findings from dermatology, neurology, and ophthalmology were collected. Logistic regression was used to identify factors associated with glaucoma-related outcomes. Primary outcomes included glaucoma development, progression to surgery, and treatment failure. Failure was defined as having a final intraocular pressure >21 mmHg, devastating complication, or <=20/200 vision. Twenty-three of 44 SWS patients (52.3%) developed glaucoma, and 6 of 23 patients (26.1%) had both eyes affected. Sixteen of 29 eyes (55.2%) required surgery, and 29.6% overall met our failure criteria (mean follow-up: 5.1 ± 4.3 years). Glaucoma diagnosis was associated with bilateral port-wine birthmarks (PWBs; odds ratio [OR] 5.9; 95% confidence interval [CI] 1.3-43.2), PWB with any lower eyelid involvement (OR 9.7, 95% CI 2.6-44.5), and choroidal hemangiomas (OR 3.8, 95% CI 1.1-13.8), but was not associated with upper eyelid or leptomeningeal angiomas, seizures, prior hemispherectomy, or pulsed-dye laser. Eyes that progressed to surgery were more likely to have PWB affecting the lower eyelid (OR 33.7, 95% CI 4.5-728.0). No clinical or demographic factors were associated with treatment failure. In most cases, angle surgery failed (72.7%) but was a temporizing measure before subconjunctival filtering surgery.

Rapid Retinal Nerve Fiber Layer Thinning in the Unaffected Contralateral Eyes of Patients With Unilateral Normal-Tension Glaucoma
The unaffected eyes of unilateral patients with NTG showed faster RNFL thinning than healthy control eyes, more obviously in the TI sector, and were likely to progress faster when they had a thicker baseline RNFL, and when the NTG eyes had a worse VF MD. In unilateral patients with NTG, initiation of prophylactic treatment could be considered for the unaffected eyes when they are accompanied by a risk of developing glaucoma.
Summary
A Retrospective Observational Study
[Posted 22/Oct/2024]
AUDIENCE: Ophthalmology, Internal Medicine
KEY FINDINGS: The unaffected eyes of unilateral patients with NTG showed faster RNFL thinning than healthy control eyes, more obviously in the TI sector, and were likely to progress faster when they had a thicker baseline RNFL, and when the NTG eyes had a worse VF MD. In unilateral patients with NTG, initiation of prophylactic treatment could be considered for the unaffected eyes when they are accompanied by a risk of developing glaucoma.
BACKGROUND: Objective of the study is to observe the rate of progressive retinal nerve fiber layer (RNFL) thinning in the unaffected eyes of patients with unilateral normal-tension glaucoma (NTG), in comparison with that of healthy subjects, and to identify the factors associated with progressive RNFL thinning. 95 patients with unilateral NTG and 61 healthy controls were participated.
DETAILS: This study included unilateral NTG and healthy control subjects who were followed up for longer than 4 years and in whom at least 5 reliable retinal nerve fiber layer thickness (RNFLT) measurements were performed using OCT. Factors associated with the rate of thinning of the unaffected eyes of unilateral patients with NTG were identified using regression analysis. Retinal nerve fiber layer thickness decreased significantly in both the unaffected eyes of unilateral patients with NTG and the healthy eyes (both P 0.001). The RNFL thinning was significantly faster in the unaffected eyes of unilateral patients with NTG than in the healthy eyes (P 0.001), specifically in the temporal-inferior (TI) sector (P = 0.003). Factors associated with faster RNFL thinning in the unaffected eyes of unilateral patients with NTG were thicker baseline RNFL of the unaffected eyes (P = 0.002) and a worse visual field (VF) mean deviation (MD) in the NTG eyes (P = 0.040). In the healthy controls, the rate of RNFL thinning in the contralateral eyes was the only factor associated with faster thinning (P = 0.007).
