Sustained Release Therapies with the Prostaglandin Analogues Intracameral Implants.

The travoprost intracameral implant was recently approved by the US Food and Drug Administration for sustained release medical treatment of open-angle glaucoma in the USA. The approval represents a substantial and progressive step forward in the area of sustained-release glaucoma therapy. Topical intraocular pressure-lowering medications for the treatment of glaucoma are faced with a host of challenges for long-term and usually lifelong care. A changing paradigm in glaucoma management involves first-line interventions with laser modalities, micro-invasive surgeries, and sustained-release treatment platforms. Future needs in the area of sustained-release therapy include a non-prostaglandin drug delivery platform and longer-term treatments that do not require surgical reintervention.

This review article investigates the importance of astigmatic correction and seeks to uncover the critical components of preoperative evaluation. With the rapid growth of new technologies and techniques, this article aims to also catalogue and clarify the multitude of astigmatism treatment options available for the cataract surgeon.

Pregnancy outcomes in the medical management of glaucoma: An international multicenter descriptive survey.

PURPOSE: To determine if glaucoma medications are associated with pregnancy and/or postnatal complications. METHODS: Multicenter descriptive survey. Subjects were female patients 18-45 years who were previously pregnant with a diagnosis of glaucoma or ocular hypertension prior to pregnancy. Chart review queried diagnosis, glaucoma severity, and race. Survey questions were asked for each pregnancy and queried pregnancy age, medications used, and pregnancy outcomes/complications. RESULTS: 114 pregnancies of 56 patients (mean 2.0 pregnancies per patient) were included. Three pregnancies with therapeutic abortion were excluded from further analysis. Mean age during pregnancy was 29.1 ± 5.7 years. Of the 111 pregnancies, 20 (18.0%) used no medications and 91 (82.0%) used at least one medication. Medications were topical carbonic anhydrase inhibitors (n = 45), beta-blockers (n = 55), alpha-agonists (n = 56), and prostaglandin analogues (n = 28). Outcomes were: preterm contractions/labour (6.3%), miscarriage (4.5%), stillbirth (4.5%), induction of labour (11.9%), emergency/unplanned caesarean delivery (13.9%), neonatal intensive care unit (NICU) stay (15.8%), congenital anomalies (8.1%), and low birth weight (10.9%). Fisher exact test assessed outcome associations with individual agents, use of any agent, and different number of agents. Alpha-agonist use was associated with NICU stay: 25.5% rate (p = 0.012) in alpha-agonist use. Most of the alpha-agonist use NICU stays occurred in pregnancies with third trimester use. All other associations were not statistically significant. CONCLUSIONS: The data from this survey suggest an overall favourable safety profile for topical glaucoma medications in pregnancy, but further investigation is needed. Caution should be employed regarding third trimester alpha-agonist use owing to association with NICU stay.

Intraocular Pressure in Eyes With Retinal Vein Occlusion Compared With Fellow Eyes: Study of Comparative Treatments for Retinal Vein Occlusion 2 (SCORE2) Report 27.

This cohort study investigates intraocular pressure (IOP) in eyes with retinal vein occlusion (RVO) compared with fellow, unaffected eyes.

Glaucoma Fellows-in-Training Recent Surgery Trends.

PURPOSE: The volume of microinvasive glaucoma surgery (MIGS) has increased dramatically in recent years, from 31 059 in 2013 to 69 420 in 2018. We investigated the impact of this trend on trainees by determining the proportion of glaucoma surgeries performed by fellows-in-training comprised by MIGS, trabeculectomies, and aqueous shunts. DESIGN: Retrospective analysis. PARTICIPANTS: Fellows-in-training at Glaucoma Fellowship Programs certified by the Association of University Professors of Ophthalmology Fellowship Compliance Committee (AUPO-FCC) METHODS: We analyzed aggregate summaries of surgeries performed by fellows as reported to the AUPO-FCC from the academic years (AYs) beginning in 2014 through AY 2020. Each report lists the average number of procedures performed per surgery type per fellow. We combined these averages to create a sum "average number surgeries performed" across glaucoma surgeries and computed the proportion that each surgery type (MIGS, trabeculectomies, and aqueous shunts) represented within the total average number of surgeries performed per year. MAIN OUTCOME MEASURES: Average number of procedures performed for each surgery type as well as the proportion that each surgery type (MIGS, trabeculectomies, and aqueous shunts) represented within the total average number of procedures performed per year. RESULTS: Average number of MIGS performed is significantly greater in later years compared with earlier years (P < 0.001). The average number of trabeculectomies performed between AYs 2014 and AY 2020 ranged from 21.8 to 31.9 and decreased, on average, by - 0.80 year-to-year. The average number of aqueous shunts performed between AY 2014 and AY 2020 ranged from 44.7 to 49.5, with an average increase of + 0.8 year-to-year. The total average number of procedures performed (across all 3 surgical subtypes) increased on average by + 4.8 procedures each year. CONCLUSIONS: Since 2014, fellows are performing increasing numbers of MIGS procedures, whereas the total number of trabeculectomies and aqueous shunt surgeries performed each year remain similar, resulting in a net increase in total number of procedures performed per fellow each year. This suggests the increase in MIGS is not associated with a substantial decline in trabeculectomies or aqueous shunts performed by glaucoma fellows.

Topical netarsudil for treatment of glaucoma with elevated episcleral venous pressure: A pilot investigation in sturge-weber syndrome.

PURPOSE: Topical netarsudil 0.02% may reduce intraocular pressure (IOP) by decreasing episcleral venous pressure (EVP), which carries theoretical utility for glaucoma associated with elevated EVP. A role for netarsudil in patients with elevated EVP is evaluated in a pilot investigation using a cohort of individuals with Sturge-Weber syndrome (SWS). METHODS: Retrospective study of patients with SWS and glaucoma who were treated with netarsudil. Five patients (six eyes) were identified. Data collected included demographics, visual acuity, IOP, glaucoma medical and surgical treatments, and adverse effects of netarsudil. RESULTS: Mean age was 13.6 ± 8.5 years. EVP elevation was presumed based on clinical stigmata and/or historical features. Mean number of baseline glaucoma medications was 3.3 ± 1.2. There was a significant reduction in the IOP at netarsudil initiation (mean 26.2 ± 4.5 mmHg) to 1 month of netarsudil therapy (mean 20.2 ± 3.8 mmHg, p = 0.0283) and latest IOP on netarsudil (mean 17.6 ± 1.4 mmHg, p = 0.0034). Mean duration of netarsudil therapy was 18.7 ± 11.8 months. Three patients required additional glaucoma procedures; one patient required an additional glaucoma medication. Three eyes (50%) developed conjunctival hyperemia. One patient discontinued netarsudil at 29 months, to reduce drop burden. CONCLUSIONS: Netarsudil can effectively reduce IOP in patients with SWS, even when used as a fourth or fifth glaucoma medication. A possible role for netarsudil in the management of patients with elevated EVP is suggested pending further future investigations.

Microinvasive glaucoma surgeries: critical summary of clinical trial data with and without phacoemulsification.

PURPOSE OF REVIEW: To critically summarize and examine published data from randomized controlled clinical trials (RCTs) investigating the safety and efficacy of microinvasive glaucoma surgeries (MIGS) with and without cataract surgery versus cataract surgery alone. RECENT FINDINGS: Three RCTs with standardized outcomes and rigorous methodology demonstrate superiority of the iStent (Glaukos), CyPass (Alcon), and Hydrus (Alcon) MIGS devices in combination with cataract surgery versus cataract surgery alone. The trials all involved medication washouts at baseline and also after 24 months of follow-up. In each of the trials, a greater proportion of participants randomized to the combined MIGS procedures achieved at least 20% unmedicated intraocular pressure (IOP) lowering compared with cataract surgery alone. With the exception of the CyPass device, which has been voluntarily withdrawn from the market, adverse events associated with MIGS were acceptable and consistent with routine intraocular surgeries. Follow-up studies demonstrate sustained efficacy, greater probabilities of visual field preservation, increased cost-effectiveness, and enhanced quality of life associated with MIGS procedures. SUMMARY: Data related to MIGS platforms for treatment of open-angle glaucoma with or without co-existing cataract supports their continued adoption in clinical practice. Future studies comparing various techniques and devices in a standardized fashion are needed.

Surgical outcomes of excisional goniotomy using the kahook dual blade in severe and refractory glaucoma: 12-month results.

OBJECTIVES: To describe the efficacy and safety of goniotomy with trabecular meshwork excision using the Kahook Dual Blade (KDB, New World Medical Inc., Rancho Cucamonga, CA) in patients with severe or refractory glaucoma. METHODS: This retrospective multicentre case series reports on 40 eyes with severe or refractory open-angle glaucoma that underwent standalone or combined KDB goniotomy and were followed for 12 months post-operatively in the United-States, Mexico and Switzerland. Surgical success was defined as an intraocular pressure (IOP) reduction ≥20% from baseline at 12 months, with fewer medications than preoperatively. Mean IOP and antiglaucoma medication reduction, probabilities of achieving an IOP ≤16 or 18 mmHg, and adverse events were also analysed. RESULTS: Mean IOP decreased from 18.1 ± 5.0 mmHg at baseline to 14.8 ± 3.7 mmHg at 12 months (18.2% reduction, P < 0.001). Concomitantly, the mean number of glaucoma medications decreased from 2.5 ± 1.4 to 1.7 ± 1.2 (32% reduction, P = 0.002). The proportion of eyes achieving an IOP reduction of more than 20% from baseline was 37.5% (n = 15) at 12 months. At 12 months, 67.5% and 82.5% achieved a medicated IOP ≤ 16 and ≤18 mmHg, respectively. No severe complications were reported. CONCLUSION: Excisional goniotomy with KDB achieves a statistically significant IOP and antiglaucoma medication reduction in severe or refractory glaucoma over a period of 12 months. While its efficacy decreases with time, its favourable safety profile makes it a potentially useful primary or adjunctive procedure in high-risk eyes.

Deadbolt cataract due to misplanted minishunt.

A 62-year-old woman with stable unilateral glaucoma in the left eye presented for a cataract consultation. In 2010, laser peripheral iridotomies (LPI) were performed on both eyes by a different provider. Her postoperative course was complicated by a recalcitrant steroid response with a highest intraocular pressure (IOP) of 65 mm Hg in the left eye. A trabeculectomy with a glaucoma minishunt (EX-PRESS, Alcon) was then performed by that provider (Supplemental Figure 1, http://links.lww.com/JRS/A603). Thereafter, IOP control of the left eye was normalized and maintained without topical antiglaucoma medications. Historically, her right eye has been always her better eye. Recently, she noticed metamorphopsia in her left eye. Her ocular history was also notable for high refractive errors requiring continuous spectacles wear, possible mild refractive amblyopia of the left eye, history of submacular choroidal nevus with drusen in the right eye, and an epiretinal membrane (ERM) with macular pucker in the left eye. Her husband is an optician. Both inquire about refractive cataract surgery options to correct astigmatism and presbyopia; both have reservations regarding cost and visual quality associated with diffractive optic intraocular lenses (IOLs). Her deteriorating visual acuity in both eyes affects her ability to work. Her corrected distance visual acuity was 20/40 in both eyes (pinhole, no help) while wearing spectacles according to a prescription of -8.50 diopters (D) +1.50 D × 106 for the right eye and -13.00 D +3.25 D × 057 for the left eye. Her corrected near visual acuity was 14/14 in both eyes with the abovementioned prescription and a +3.00 D add. Central corneal thickness was 618 µm in the right eye and 631 µm in the left eye. IOP was 20 mm Hg in the right eye and 10 mm Hg in the left eye on no antiglaucoma medications. Pertinent findings on slitlamp examination included bilateral dermatochalasis, a shallow diffuse thick bleb superiorly in the left eye only, patent LPI superiorly in both eyes, nuclear sclerotic and cortical cataracts in both eyes (with prominent focal spoke superiorly left eye only) (Figure 1, A-C). Fundus photos show posterior vitreous detachment in both eyes, ERM with macular pucker in the left eye, and submacular choroidal nevus (2.5 × 3.0 disc diameter size) with overlying drusen in the right eye (Supplemental Figure 2, A, http://links.lww.com/JRS/A604). Gonioscopy revealed open angles in both eyes, albeit with focal narrowing without synechiae superiorly in the left eye only (Figure 1, D-FJOURNAL/jcrs/04.03/02158034-202207000-00020/figure1/v/2022-06-24T130746Z/r/image-tiff). Most importantly, however, the distal tip of the minishunt was not positioned as expected in the anterior chamber; rather, it was noted to pierce the peripheral iris near the iris root superiorly. Most of the minishunt shaft and spur were positioned in the posterior chamber with the distal tip penetrating into the superior aspect of the capsular bag and cataract in the left eye-like a deadbolt. Visual field testing showed a full field in the right eye and an inferior nasal step in the left eye (Supplemental Figure 2, B, http://links.lww.com/JRS/A604). In addition to slitlamp, gonioscopic, and fundus photos, we also obtained optical coherence tomography of the macula and nerve (Supplemental Figure 2, C, http://links.lww.com/JRS/A604), optical biometry, ultrasound biomicroscopy, endothelial cell counts, and corneal topography (Supplemental Figure 3, http://links.lww.com/JRS/A605). How would you counsel this patient regarding her glaucoma condition, the misplanted minishunt, and her cataract surgery and IOL options? How would you manage the misplanted minishunt? What surgical approaches or specific techniques would you consider for cataract removal and visual rehabilitation?

Refractive Outcomes for Combined Phacoemulsification and Glaucoma Drainage Procedure.

INTRODUCTION: To evaluate the refractive outcome of combined cataract extraction and glaucoma drainage device (GDD) surgery. METHODS: Patients who had undergone combined phacoemulsification with GDD surgery [Baerveldt, Abbott Medical, Abbott Park (IL) or Ahmed valve, New World Medical, Rancho Cucamonga (CA)] between June 2009 and August 2017 were included in the study. The main outcome measure evaluated was whether or not spherical equivalent (SE) between ± 1D from target refraction was achieved at 3-6 months postoperatively. RESULTS: The final analysis included 42 eyes of 38 patients who underwent combined phacoemulsification and GDD surgery. A refractive outcome of spherical equivalent (SE) between ± 1D of the target refraction was achieved in 30 of 42 eyes (71.43%) at 3-6 months after surgery. Mean preoperative axial length (AL) of eyes with postoperative SE outside ± 1D from target (SD = 0.98, p = 0.003) was noted to be 25.37 ± 0.98 mm (longer mean AL) and that of eyes with SE between ± 1D (SD = 0.89, p = 0.000) was found to be 23.34 ± 0.89 mm (average mean AL). Twelve (29%) eyes were noted to have a mean 0.52D (SD = 0.49; range 0.02-1.49) of corneal astigmatism induced by combined surgery. Age, central corneal thickness, preoperative anterior chamber depth, and pre- and postoperative intraocular pressure did not significantly affect refractive outcomes. CONCLUSION: Refractive outcomes within 1.00D of the target refraction were achieved in most patients undergoing a combined surgical approach. Longer AL was a risk factor among patients with refractive change > 1.00D from target.

Experience with netarsudil 0.02% and latanoprostene bunod 0.024% as adjunctive therapy for glaucoma.

PURPOSE: To assess the effectiveness and safety of adjunctive topical netarsudil 0.02% and latanoprostene bunod 0.024% in patients with glaucoma. METHODS: A retrospective, multi-center, cohort study of patients with glaucoma treated with netarsudil 0.02% or latanoprostene bunod from five tertiary care centers. Inclusion criteria included patients with glaucoma treated with either medication as adjunctive therapy. Outcomes included mean absolute intraocular pressure (IOP) reduction and relative IOP reduction from baseline. Adverse reactions and reasons for discontinuation were reported. One-way analysis of variance, Kruskal-Wallis rank sum test, and Mann Whitney U test compared the outcomes. RESULTS: A total of 95 eyes (95 patients) on netarsudil and 41 eyes (41 patients) on latanoprostene bunod were analyzed. Mean duration of use was 54.3 ± 28 days for netarsudil and 82.9 ± 51.2 days for latanoprostene bunod. At the final visit, mean IOP reduction was 3.9 ± 4.6 mmHg (17.5 ± 6.0%) (p < 0.0001) with netarsudil and 2.9 ± 3.7 mmHg (13.6 ± 16.3%) (p < 0.0001) with latanoprostene bunod. IOP lowering did not depend on baseline number of IOP-lowering medications. The most common reason for discontinuation was non-effectiveness in both groups. CONCLUSION: Similar to monotherapy, netarsudil and latanoprostene bunod demonstrated efficacy in lowering IOP when used as adjunctive therapy.

Intraocular Pressure-Related Events After Anti-Vascular Endothelial Growth Factor Therapy for Macular Edema Due to Central Retinal Vein Occlusion or Hemiretinal Vein Occlusion: SCORE2 Report 16 on a Secondary Analysis of a Randomized Clinical Trial.

IMPORTANCE: Intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections are used to treat a variety of posterior segment conditions, including some associated with glaucoma, such as macular edema due to central retinal vein occlusion (CRVO). Therefore, information regarding intraocular pressure (IOP)-related events associated with anti-VEGF therapies is important to help balance the risks and benefits over the course of therapy. OBJECTIVE: To investigate IOP-related events among participants in the Study of Comparative Treatments for Retinal Vein Occlusion 2 (SCORE2). DESIGN, SETTING, AND PARTICIPANTS: Secondary analysis of a randomized clinical trial that included 312 participants with macular edema secondary to CRVO or hemiretinal vein occlusion (HRVO) who were not taking IOP-lowering medications at baseline. First randomization occurred on September 14, 2014, and contained data through data freeze on April 1, 2020. Analysis took place from April 2020 through December 2020. INTERVENTIONS: Study participants were initially randomized to 6 monthly intravitreal injections of aflibercept or bevacizumab. At month 6, protocol-defined good responders were rerandomized to continued monthly or treat-and-extend dosing of their originally assigned study drug, and protocol-defined poor or marginal responders were switched to alternative treatment. After month 12, participants were treated as per investigator discretion. MAIN OUTCOMES AND MEASURES: Three different outcomes: (1) IOP elevation more than 10 mm Hg from baseline, (2) IOP to a level higher than 35 mm Hg, and (3) IOP-lowering incisional or laser surgery. RESULTS: Of the 312 participants meeting inclusion criteria (138 [44.2%] were female; mean [SD] age, 67.8 [12.1] years), 25 (8.0%) had IOP elevation more than 10 mm Hg over baseline through month 60, and 5 (1.6%) had IOP higher than 35 mm Hg. The 60-month Kaplan-Meier cumulative incidence of IOP elevation more than 10 mm Hg over baseline was 0.13 (95% CI, 0.08-0.19), and the 60-month Kaplan-Meier cumulative incidence of IOP higher than 35 mm Hg was 0.02 (95% CI, 0.01-0.06), and did not differ among participants initially randomly assigned to receive aflibercept or bevacizumab. Three participants (1.0%) underwent IOP-lowering incisional surgery, and 3 participants (1.0%) underwent IOP-lowering glaucoma laser surgery. CONCLUSIONS AND RELEVANCE: Intravitreal anti-VEGF injections are used to treat some conditions associated with glaucoma, such as macular edema due to CRVO, and the rates of IOP-related events in this trial support monitoring IOP in eyes treated with anti-VEGF therapy for macular edema associated with CRVO or HRVO for up to 60 months. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01969708.

Glaucoma Care of Incarcerated Patients at an Academic Institution: A Case-Control Study.

PURPOSE: To evaluate medication and follow-up adherence in incarcerated patients examined at an academic glaucoma clinic, in comparison to nonincarcerated controls. METHODS: Retrospective, case-control study. Consecutive prisoners presenting for initial visits in the Glaucoma Clinic at the Illinois Eye and Ear Infirmary between December 2015 and December 2017 were included in the study. Nonincarcerated patients seen in the same Glaucoma Clinic with similar initial visit dates, age, race, sex, and disease severity were selected as controls. Glaucoma Clinic visits from each patient were reviewed until December 2018. Examination information, surgical intervention, follow-up and treatment recommendations, and patient-reported medication usage were recorded for each visit. Number of visits, loss to follow-up, follow-up delays, and medication nonadherence were studied as primary outcome measures. RESULTS: Twenty-four prisoners and 24 nonincarcerated controls were included. Prisoners had an average of 2.46 ± 2.38 visits during the study period, compared to 5.04 ± 3.25 for controls (P = 0.001). Follow-up visits occurred more than 30 days after the recommended follow-up time in 57.4% (95% confidence interval [CI]: 44.2%-70.6%) of prisoners, compared to 17.9% (95% CI: 10.2%-25.6%) of controls (P < 0.00001). 70.8% of prisoners (95% CI: 66.3-74.5%) were lost to follow-up, compared to 29.2% of controls (95% CI: 25.5%-32.9%; P < 0.01). Medication nonadherence rates were similar between prisoners (13.6%; 95% CI: 12.1%-15.2%) and controls (12.0%; 95% CI: 11.4%-12.6%; P = 0.78). CONCLUSIONS: Glaucoma follow-up adherence was significantly worse in prisoners compared to a nonincarcerated control population. Further study into causative factors is needed.

Oral acetazolamide for intraocular pressure lowering: balancing efficacy and safety in ophthalmic practice.

Introduction: Systemic acetazolamide is an efficacious adjunct to topical therapy to lower intraocular pressure (IOP) in glaucomatous eyes. This article aims to provide a comprehensive review for how best to use the agent in ophthalmic practice.Areas covered: This article will review the history, mechanism of action, methods of observing efficacy, indications for IOP lowering, side effects, allergy information including discussion of limited cross-reactivity between antimicrobial and non-antimicrobial sulfonamides, formulations, dosing and monitoring of acetazolamide. To select articles for this review, an electronic search was conducted using the PubMed database and cross-referencing was conducted for relevant literature.Expert opinion: The benefits of oral carbonic anhydrase inhibitor therapy can outweigh the risks in many circumstances. It is important that eye care practitioners work together with a patient's primary care practitioner to monitor for and mitigate risks. Greater education is needed with regard to the allergy profile of these powerful agents. Though not often a first-line option, oral carbonic anhydrase inhibitors remain pivotal and play in important role in delivery of eye care.

Recent developments in the use of optical coherence tomography for glaucoma.

PURPOSE OF REVIEW: The aim of this article is to summarize findings of recent reports highlighting the utility of novel optical coherence tomography (OCT) parameters in the diagnosis and monitoring of glaucomatous optic neuropathy. RECENT FINDINGS: Optic nerve head (ONH), retinal nerve fiber layer (RNFL), and macular parameters show high levels of diagnostic capability. The Bruch's membrane opening-minimum rim width (BMO-MRW) measurement is a novel ONH parameter obtained using the Spectralis SD-OCT device (Heidelberg Engineering, Inc., Heidelberg, Germany). The inferotemporal BMO-MRW sector shows the highest diagnostic performance for this parameter. Minimum ganglion cell and inner plexiform layer thickness shows the highest diagnostic performance among macular parameters obtained with the Cirrus HD-OCT (Carl Zeiss, Inc., Dublin, CA, USA). Optic nerve head, macular, and retinal nerve fiber layer parameters are not interchangeable across protocols generated by varying OCT manufacturers. Novel machine-learning algorithms show promise with regards to achieving higher levels of diagnostic accuracy using OCT imaging platforms. SUMMARY: Digital imaging in glaucoma continues to evolve with novel parameters of the optic nerve head, retinal nerve fiber layer, and macula. Diagnostic abilities of these parameters are high and complementary to each other.

Gabapentin for presumed neuropathic ocular pain.

PURPOSE: To report a case of chronic neuropathic ocular pain in a patient without visual complaints. OBSERVATIONS: A 37-year-old male with a history of bilateral laser-assisted in situ keratomileusis (LASIK) presented with pain symptoms of 8 months duration in the left eye. The prior LASIK surgery was complicated by corneal ectasia in the left eye requiring penetrating keratoplasty and subsequent placement of a glaucoma drainage implant for uncontrolled, elevated intraocular pressure. The patient was evaluated with a complete clinical examination, including Goldmann applanation tonometry, dilated fundus examination, fluorescein angiography, optical coherence tomography, and magnetic resonance imaging. After 3 weeks of treatment with gabapentin 300 mg BID, the patient reported complete resolution of the ocular pain. CONCLUSIONS AND IMPORTANCE: The pathophysiology of neuropathic ocular pain remains poorly understood. Clinical evaluation often reveals minimal ophthalmic exam findings, leading to an underdiagnosis of the condition by ophthalmologists. Gabapentin may be an underutilized medication in the treatment of chronic ocular pain.

Glaucoma Care of Prison Inmates at an Academic Hospital.

Importance: Glaucoma care for prison inmates is underrepresented in the literature even though managing the treatment of such patients may provide unique challenges. Objectives: To evaluate the glaucoma profile of prison inmates treated at an academic ophthalmology center and to report on the medical and surgical management and follow-up metrics. Design, Setting, and Participants: This retrospective cohort study assessed data from 82 incarcerated patients treated at the glaucoma clinic, an academic referral center at the University of Illinois at Chicago, between January 2013 and December 2017. Main Outcomes and Measures: Diagnosis, glaucoma severity, medical and surgical interventions, and patient-reported medication adherence were recorded for each visit. Recommended and actual follow-up times were recorded and compared. Data analyses were conducted from January 2013 to December 2018. Results: In total, 82 patients (161 eyes) had 375 visits during the study period. All patients were male and ranged from 20 to 75 years of age (mean [SD] age, 50.8 [11.9] years). Most participants were black patients (65 [79.3%]). The most common diagnoses were primary open-angle glaucoma (POAG; 53 eyes [32.9%]) and POAG suspect (52 eyes [32.3%]). Glaucoma severity ranged from mild (25 of 77 eyes [32.5%]) to advanced (41 of 77 eyes [53.2%]). Overall, 59 patients (73.2%) were treated medically with up to 4 topical agents (40.0%). Of those treated, 70.0% of patients (95% CI, 57.7%-81.2%) reported medication nonadherence during at least 1 visit. Medication nonadherence was more common among those taking 4 different topical medications (21 of 24 [87.5%]) compared with others taking fewer medications (20 of 35 [57.1%]), for a difference of 30.4% (95% CI, 7.0%-53.6%; P = .02), and among those with advanced disease (22 of 26 [84.6%]) compared with glaucoma suspect (6 of 13 [46.2%]), for a difference of 38.4% (95% CI, 9.3%-67.5%; P = .02). Nineteen office procedures, including laser peripheral iridotomy and laser trabeculoplasty, were performed on 14 eyes. Seventeen incisional glaucoma procedures were performed on 15 eyes, including glaucoma drainage device implant (11 procedures [64.7%]) and trabeculectomy (3 procedures [17.6%]). Only 26.6% of return office visits (95% CI, 21.3%-32.3%) occurred within the recommended follow-up time frame. Furthermore, 93 patients (34.8%; 95% CI, 28.2%-40.0%) were seen more than 1 month after the recommended follow-up. Conclusions and Relevance: Despite incarceration in prison, where medication administration and appointment attendance are theoretically controlled, the results of this study suggested that substantial medication and follow-up nonadherence exists among inmates.

Intraocular Lens Implantation In The Ciliary Sulcus: Challenges And Risks.

PURPOSE: This article reviews the current literature on the risks and challenges associated with intraocular lens (IOL) implantation in the ciliary sulcus. RECENT FINDINGS: The development of IOLs designed specifically for placement in the ciliary sulcus continues to be an area of interest for the ophthalmic industry. Currently the one-piece PMMA (polymethylmethacrylate) lens or a three-piece IOL are the best available options for IOL placement in the ciliary sulcus space. Single piece acrylic (SPA) IOLs are not designed for sulcus placement and there is growing evidence of chronic complications related to their use in the ciliary sulcus. Many of these eyes ultimately require surgical intervention, including lens exchange. Endoscopic imaging and ultrasound biomicroscopy (UBM) have enabled a better understanding of ciliary sulcus anatomy and measurements in the living eye. SUMMARY: When the capsular bag is compromised, IOL placement in the ciliary sulcus is a reasonable option. In these circumstances, appropriate choice of IOL, knowledge of the sulcus anatomy, and correct technique can improve results and reduce postoperative complications.

Netarsudil and latanoprost ophthalmic solution for the reduction of intraocular pressure in open-angle glaucoma or ocular hypertension.

Introduction: Netarsudil and latanoprost ophthalmic solution (0.02%/0.005%) is indicated for intraocular pressure (IOP) lowering in open-angle glaucoma (OAG) or ocular hypertension (OHTN). The once-daily agent combines the mechanism of action for each of the individual components and provides a new avenue for long-term intraocular pressure control. This review aims to cover the agent's current efficacy and safety data and opine as to its role in glaucoma management.Areas covered: This article will cover Phase II-III clinical efficacy and safety data as well as basic science literature pertaining to the agent's mechanism of action and pharmacodynamics. In selecting articles for inclusion in this review, a literature search using the PubMed database was carried out. Cross-referencing was carried out where applicable. We did not use any date or language restrictions in electronic searches.Expert opinion: Netarsudil and latanoprost ophthalmic solution plays a pivotal role in management of individuals with OAG and OHTN. The agent may be used as first-line therapy to provide substantial IOP-lowering or when additional lowering is indicated and prostaglandins have provided insufficient IOP lowering. The once-daily dosing regimen decreases the risk of inadequate treatment due to nonadherence.

Outcome of Botulinum Toxin-A intraprostatic injection for benign prostatic hyperplasia induced lower urinary tract symptoms: A prospective multicenter study.

INTRODUCTION: Our aim was to determine the factors predicting the outcome of intraprostatic injection of Botulinum Toxin-A (BTX-A) in the treatment of benign prostatic hyperplasia (BPH)-induced lower urinary tract symptoms (LUTS) and to evaluate its efficacy and safety. METHODS: Between September 2016 and May 2018, 45 Egyptian patients, with BPH-induced LUTS were included; the indication was a failure of medical treatment, unfit, or refusing surgical intervention. Measurements of prostate size by TRUS, total PSA level before and 12 weeks after injection. IPSS, uroflow, and postvoiding residual urine (PVR) were measured before injection, 2, 4, 8 and 12 weeks postinjection. 100 U BTX-A vial was diluted with 10 mL of saline then injected into the transition zone at base and midzone of the prostate by TRUS. RESULTS: The mean patients' age was 64.4 ± 6.6 years. Mean baseline IPSS 24.06 decreased to 18.75 at 2 weeks and progressively decreased to 16.37 at 12 weeks (P < 0.001), Q max of 9.08 mL/s. increased to 10.44 at 2 weeks and 11.44 at 12 weeks (P < 0.001), mean prostate volume was 67.44cc; decreased to 66.06cc (P < 0.001) at 12 weeks and mean residual urine was 82.62 mL and decreased to 57.66 mL at 12 weeks. DISCUSSION: Intraprostatic injection of BTX-A as modality treatment of LUTS/BPH significantly improve IPSS, Q max , PVR, and decrease prostate volume. We can suspect better results with this line of treatment in patients with IPSS ≤ 22 and Q max ≤ 10 mL/min and prostate volume ≤ 56.5cc.
