Purpose: This study evaluates the long-term adjunctive use of netarsudil ophthalmic solution 0.02% in lowering IOP in patients with refractory glaucoma.

Methods: This retrospective chart review study was conducted at a tertiary care center. Patients who were prescribed add-on netarsudil therapy and on ≥ 3 topical glaucoma medications from 01/01/2018 to 08/31/2020 were reviewed. 47 patients (69 eyes) met the inclusion criteria. Baseline IOPs prior to the addition of netarsudil were compared to IOPs measured at 3-, 6-, and 12-month intervals. Any patients with inadequate follow-up or who had glaucoma surgery after netarsudil initiation were excluded.

Results: Median baseline IOP (± SD) was 21 ± 5.8 mmHg (median of 2 visits prior to initiation of netarsudil). At 3-month follow-up, 64 eyes had a median IOP of 16 ± 6.7 mmHg (p < 0.01). At 6-month follow-up, 56 eyes had a median IOP of 18 ± 4.6 mmHg (p < 0.01). At 12-month follow-up, 44 eyes had a median IOP of 15 ± 6.8 mmHg (p < 0.01). At the conclusion of the study, 64% of eyes reached 1 year follow-up due to several reasons.

Conclusions: Patients with refractory glaucoma showed statistically and clinically significant IOP reductions on netarsudil. IOP reduction was stable long-term with the largest decrease in IOP seen at 12 months. Although some patients will still go on to require further laser or incisional surgery, for most patients netarsudil is an effective treatment for adjunctive use in refractory glaucoma.

Purpose: To evaluate the clinical outcomes following bilateral implantation of the AcrySof™ IQ Vivity™ toric extended depth of focus (EDOF) intraocular lens (IOL).

Design: Prospective interventional case series.

Methods: Patients with bilateral significant cataracts and pre-existing corneal astigmatism underwent cataract surgery and implantation with the AcrySof™ IQ Vivity™ toric IOL. Dominant eyes were targeted at emmetropia and non-dominant eyes at -0.50D. Primary endpoints were binocular uncorrected distance (UDVA), intermediate (UIVA at 66 cm) and near (UNVA at 40 cm) acuities at 3 months. Secondary outcomes were corrected distance (CDVA), distance corrected intermediate (DCIVA) and distance corrected near (DCNVA), refractive predictability, rotational stability, binocular defocus curve, contrast sensitivity, Questionnaire for Visual Disturbances (QUVID) and Visual Function Index (VF-14) questionnaire scores. All visual acuities were converted to logarithm of minimum angle of resolution (logMAR) for analysis.

Results: 30 patients underwent uneventful phacoemulsification. The mean binocular UDVA, UIVA and UNVA were 0.06 ± 0.12, 0.11 ± 0.10 and 0.26 ± 0.10 respectively. The mean refractive spherical equivalent (MRSE) for dominant and non-dominant eyes were - 0.07D ± 0.27 and - 0.12D ± 0.54 respectively. 92.4% of dominant eyes and 84.6% of non-dominant eyes within 0.50D of target. The mean IOL rotation was 3.85° ± 5.09 with 86.7% of eyes with less than 5° of rotation. 26.7%, 20% and 36.7% of patients reported starbursts, haloes and glare respectively. The mean VF-14 score was 91.77.

Conclusion: Bilateral implantation of the AcrySof™ IQ Vivity™ Toric IOL resulted in very good unaided visual acuities for far and intermediate distance with functional near vision. Dysphotopsias were reported but despite this, a high level of visual function was achieved.

Purpose: We compared corneal endothelial cell (CED) loss after Ex-Press (EXP) surgery between patients with primary open-angle glaucoma (POAG) and pseudo-exfoliation glaucoma (PEX).

Patients and methods: This was a single-facility retrospective study. We included glaucoma patients who had undergone EXP surgery and were followed up > 3 years. We measured the CED before and after (at 12, 24, and 36 months) EXP surgery by noncontact specular microscopy and compared the means of the CED values and CED survival ratios after EXP surgery by paired t-test.

Results: We included 119 eyes that underwent EXP surgery, including 60 POAG eyes and 59 PEX eyes. In the POAG group, the mean CED decreased from 2389 ± 321 at baseline to 2230 ± 424 cells/mm² after 3 years. In the PEX group, the mean CED decreased from 2111 ± 510 at baseline to 1845 ± 628 cells/mm² after 3 years. At the 3-year follow-up, the CED survival ratio was 93.3 ± 12.5% in the POAG group and significantly lower, at 85.0 ± 19.5%, in the PEX group (p = 0.0064). Two cases in the PEX group developed bullous keratopathy.

Conclusions: EXP surgery decreased the corneal endothelial cell populations in PEX patients faster than POAG patients.

Purpose: To compare the clinical outcomes of myopiacorrected with corneal-wavefront-guided (CWG) laser in situ keratomileusis (LASIK) with AMARIS 1050S (SCHWIND eye-tech-solutions GmbH & Co. KG) and corneal-topography-guided (CTG) LASIK with WaveLight EX500 (Alcon Laboratories, Fort Worth, TX).

Methods: In this prospective, pseudo-randomized expanded cohort study, a total of 266 patients were subjected to binocular LASIK surgery, either with WaveLight EX500 (WaveLight group) or Amaris 1050S (AMARIS group) platforms. Data related to right eyes were selected for analysis. Corneal higher-order aberration (HOA) was selected as the primary endpoint; while visual acuity and refraction were the secondary endpoints. All the endpoints were assessed at 3 months postoperatively.

Results: There were 134 eyes in the AMARIS group and 132 eyes in the WaveLight group. After 3 months of postoperative follow-up, spherical and coma aberrations were significantly lower (P < 0.05) in the WaveLight group (spherical aberration: - 0.104 ± 0.199 µm; coma aberration: - 0.117 ± 0.202 µm) in comparison with the AMARIS group (spherical aberrations: 0.254 ± 0.146 µm; coma aberrations: 0.316 ± 0.297 µm). In the AMARIS group, 96.3% of the eyes achieved an uncorrected distance visual acuity (UDVA) of 20/20 while in the WaveLight group, 96.2% of the eyes achieved an UDVA of 20/20. Furthermore, the mean postoperative manifest refraction spherical equivalent (MRSE) was - 0.02 ± 0.28 in the AMARIS group and - 0.05 ± 0.21 in the WaveLight group (P = 0.34).

Conclusions: Both WaveLight EX500 and Amaris 1050S LASIK showed excellent refractive and visual outcomes. In addition, the WaveLight group showed minimal spherical and coma aberrations when compared to the AMARIS group.

Purpose: Plasma rich in growth factors (PRGF) technology creates blood-derived products with growth factors that promote wound healing and regeneration. The goal of this study was to assess the potential role of PRGF products as wound modulators in trabeculectomy. Our premise is that due to PRGF's regenerative and antifibrotic properties, its use in trabeculectomy may produce a more physiological bleb, without altering IOP reduction.

Methods: A retrospective, longitudinal study was conducted in a Hospital in Portugal. Patients with eyes with open angle glaucoma were included. Trabeculectomy was performed on all patients using PRGF membrane (mPRGF) under the conjunctiva, as adjuvant. Data regarding patients' demographics and number of medications used, was collected. Intraocular pressure (IOP) before surgery, 8 days, 1 month, 3 month, 6 month, 9 month and 1 year after surgery was recorded. Bleb morphology was classified according to Moorfields Bleb Grading System 6 months after surgery.

Results: Nine eyes of 9 patients were enrolled. Mean age was 71 ± 5.1 years old. Six were male. Mean IOP decreased from 24.0 ± 8.8 mmHg pre-surgery to 12.9 ± 2.6 mmHg at one year follow-up. The number of hypotensive drugs (mean ± SD) was 4.3 ± 0.9 preoperatively and 0.8 ± 1.1 at 1-year. Complete success was defined as IOP equal to or less than 21 mm Hg without ocular hypotensive medications and qualified success as IOP equal to or less than 21 mm Hg with medications. Complete success was 66.7% and qualified success was 100% at 1 year follow-up.

Conclusion: In our study, trabeculectomy with mPRGF demonstrated both safety and efficacy. Low values of bleb height (1.6 ± 0.8) were recorded. mPRGF could improve wound healing and produce a more well-tolerated, favourable bleb, avoiding antimetabolite complications.

Purpose: To compare short-term changes in corneal endothelial cells after gonioscopy-assisted transluminal trabeculotomy(GATT).

Methods: This retrospective comparative study included 138 patients(138 eyes), and 98 of these patients underwent GATT procedure and 40 underwent SLT procedure as a control group. Changes in the corneal endothelium in patients who underwent GATT and SLT were analyzed retrospectively. Endothelial changes in the central cornea were examined using specular microscopy before and 6 months after the GATT and SLT procedure. Intraocular pressure(IOP), number of glaucoma medications, and side effects were evaluated at visits before and after two methods.

Results: One hundred and thirty-eight eyes of 138 patients with a mean age of 62.9±12.7 years in the SLT group and 62.5±11.8 years in the GATT group were included in this study. Pre-procedure mean ± SD IOP was 27.7±3.6 mmHg and 27.4±5.3 mmHg (p=0.173) 2.8±0.5 and 2.9±0.8 (p=0.204) glaucoma drugs are in the SLT and GATT group, respectively. The mean corneal endothelial cell density (CECD) in the SLT group was 2433.1±581.4 cells/mm² before the procedure and 2435.1±585 cells/mm² 6 months after the procedure, a change of 0.1±0.6% which was not statistically significant (p>0.967).The mean CECD at baseline in the GATT group was 2443.4±508.2 cells/mm² and decreased to 2290.2±527.7 cells/mm² 6 months after this procedure, representing a cell loss of 6,2±9,1% (p<0.001).

Conclusion: GATT caused more CECD damage than SLT at the sixth month after the procedure. Considering the loss of CECD in candidates for GATT, sufficient number of endothelial cells in the central cornea is recommended.

Purpose: To evaluate the quality and reliability of YouTube videos as an educational resource about myopia.

Methods: The videos were identified by searching YouTube with the keywords 'myopia' and 'nearsightedness', using the website's default search settings. The number of views, likes, dislikes, view ratio, source of the upload, country of origin, video type, and described treatment techniques were assessed. Each video was evaluated using the DISCERN, Journal of the American Medical Association (JAMA), Ensuring Quality Information for Patients (EQIP), Health On the Net Code of Conduct Certification (HONcode), and the Global Quality Score (GQS) scales.

Results: A total of 112 videos were included. The classification of videos by source indicated that the top three contributors were health channels (30 videos [26.8%]), physicians (24 videos [21.4%]), and academic centers (19 videos [16.9%]). Most of these videos originated from the United States (74 videos [66.1%]) and focused on the pathophysiology (n = 89, 79.4%) and the treatment (n = 77, 68.7%) of myopia. Statistical comparisons among the groups of video sources showed no significant difference in the mean DISCERN score (p = 0.102). However, significant differences were noted in the JAMA (p = 0.011), GQS (p = 0.009), HONcode (p = 0.011), and EQIP (p = 0.002) scores.

Conclusions: This study underscored the variability in the quality and reliability of YouTube videos related to myopia, with most content ranging from 'weak to moderate' quality based on the DISCERN and GQS scales, yet appearing to be 'excellent' according to the HONcode and EQIP scales. Videos uploaded by physicians generally exhibited higher standards, highlighting the importance of expert involvement in online health information dissemination. Given the potential risks of accessing incorrect medical data that can affect the decision-making processes of patients, caution should be exercised when using online content as a source of information.

Purpose: To evaluate the eyelid features' changes after N95 face mask (FM) usage in healthcare workers through the new type of Coronavirus Disease 2019 (COVID-19) pandemic and make a comparison with home-office workers as a control group with a computer vision algorithm.

Materials and methods: Sixty healthcare workers and forty control participants with similar demographic features included. Standardized biometric photographs which were taken before and after the COVİD-19 pandemic, analyzed by the ImageJ program (NIH, Bethesda, Md.) software. The distances between the central light reflex on the cornea and the upper (UE) and lower eyelid (LE) were recorded as the marginal reflex distances. (MRD1, MRD2 respectively) Parameters of pretarsal show (PTS) of UE and brow pupil diameter (BPD) were analyzed for both of the eyes.

Results: There were no significant differences among the groups' measurements before the COVID-19 pandemic. In healthcare workers' group after the pandemic, values of MRD1, PTS, BPD showed a significant decrease in their right eye (p = 0.001, p = 0.002, p = 0.001 respectively) and same values reduced in the left eyes as well when compared with pre-pandemic measurements. (p = 0.048, p = 0.001, p = 0.001 respectively) PTS and BPD values were decreased for both right and left eyes of the controls. (p = 0.044, p = 0.001 and p = 0.001, p = 0.001 respectively) MRD1 measurements after the pandemic showed no difference either in the right or left eyes of the control group after the pandemic. (p = 0.071 and p = 0.065 respectively).

Discussion: Results showed that both BPD and PTS values decreased independently from the previous FM usage in both of the groups. Even though MRD1 values remained within the normal values, a significant decrease was detected in the healthcare workers group which suggested the cause was newly developed upper eyelid (UE) dermatochalasis after long hours of FM usage. Although it is hard to make a truly objective evaluation both usage of standardized biometric photographs and a computer-based measurement system makes the results reliable.

Purpose: To report the long term visual outcomes and complications with use of the novel CM-T Flex scleral fixated intraocular lens (CMT-SFIOL).

Materials and methods: 116 eyes that underwent CMT-SFIOL were reviewed and 57 eyes with CMT-SFIOL that completed a 2-year follow-up were included. Main outcome measures noted were best-corrected visual acuity (BCVA) and complications. Postoperatively, follow-ups were done at 1 week (1w), 1 month (1 m), 1 year (1y) and 2-year (2y) intervals.

Results: 40 (70.17%) of 57 eyes received CMT-SFIOL for surgical aphakia. Mean follow up was 39.77 ± 8.44 months. BCVA for distance & near improved from 1.26 ± 0.84 to 0.76 ± 0.77, 0.50 ± 0.72 and 0.51 ± 0.73 & 1.28 ± 0.58 to 0.98 ± 0.49, 0.92 ± 0.44 and 0.89 ± 0.40 at 1 m, 1y and 2y respectively (p < 0.001 for all). At 1w, 10 eyes (17.54%) had corneal edema (CE) and 8 eyes (14.03%) had anterior chamber (AC) reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had vitreous hemorrhage (VH). At 1 m, 3 eyes (5.26%) had CE and 5 eyes (8.77%) had AC reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had VH. Cystoid macular edema was noted in 3 eyes (5.26%). At 1y and 2y, 2 eyes (3.5%) and 1 eye (1.75%), had CE. No decentration, dislocation, haptic exposure or retinal detachment was noted. No eyes required resurgery.

Conclusion: CM-T Flex SFIOL is an effective method to correct aphakia, with reliable and safe long-term results.

Purpose: The aim of this study was to investigate the peripapillary choroidal vascular changes in thyroid orbitopathy (TO).

Methods: The study included 20 eyes of 10 patients with active TO (aTO), 30 eyes of 15 patients with inactive TO (inaTO) and 30 eyes of 30 healthy subjects. The peripapillary choroidal vascular change was assessed with peripapillary choroidal vascular index (pCVI), peripapillary choroidal luminal area (pLA), peripapillary choroidal stromal area (pSA), peripapillary total choroidal area (pTCA).

Results: Compared to the control group, there was a reduction in the nasal and temporal areas of pCVI in both the aTO and inaTO groups (aTO vs control: nasal p = 0.001 and temporal p = 0.004; inaTO vs control: nasal p = 0.007 and temporal p < 0.001), while the inferior area was lower only in the inaTO group (p = 0.001). Compared to the other groups, the inaTO group exhibited a decrease pSA (vs aTO: total p = 0.004, inferior p = 0.02 and vs control: total p = 0.01, inferior p = 0.03), pLA (vs aTO: total p = 0.02, inferior p = 0.02, temporal p < 0.001 and vs control: total p = 0.002, inferior p < 0.001, temporal p < 0.001) and pTCA (vs aTO: total p = 0.009, inferior p = 0.01, temporal p < 0.001 and vs control: total p = 0.003, inferior p = 0.001, temporal p < 0.001).

Conclusion: The horizontal area (nasal and temporal area) of the peripapillary choroidal vascular structure may be more sensitive than the vertical area in TO patients. The first affected quadrant of RPC-VD in the active TO may be the inferior quadrant. Structural or vascular choroidal changes may occur during the chronic or post-active phase of the disease.
