[PMID: 38794131 PMCID: PMC11124470 DOI: 10.3390/ph17050561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 04/17/2024] [Accepted: 04/25/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND Bimatoprost has emerged as a significant medication in the field of medicine over the past several decades, with diverse applications in ophthalmology, dermatology, and beyond. Originally developed as an ocular hypotensive agent, it has proven highly effective in treating glaucoma and ocular hypertension. Its ability to reduce intraocular pressure has established it as a first-line treatment option, improving management and preventing vision loss. In dermatology, bimatoprost has shown promising results in the promotion of hair growth, particularly in the treatment of alopecia and hypotrichosis. Its mechanism of action, stimulating the hair cycle and prolonging the growth phase, has led to the development of bimatoprost-containing solutions for enhancing eyelash growth. AIM The aim of our review is to provide a brief description, overview, and studies in the current literature regarding the versatile clinical use of bimatoprost in recent years. This can help clinicians determine the most suitable individualized therapy to meet the needs of each patient. METHODS Our methods involve a comprehensive review of the latest advancements reported in the literature in bimatoprost formulations, which range from traditional eye drops to sustained-release implants. These innovations offer extended drug delivery, enhance patient compliance, and minimize side effects. RESULTS The vast literature published on PubMed has confirmed the clinical usefulness of bimatoprost in lowering intraocular pressure and in managing patients with glaucoma. Numerous studies have shown promising results in dermatology and esthetics in promoting hair growth, particularly in treating alopecia and hypotrichosis. Its mechanism of action involves stimulating the hair cycle and prolonging the growth phase, leading to the development of solutions that enhance eyelash growth. The global use of bimatoprost has expanded significantly, with applications growing beyond its initial indications. Ongoing research is exploring its potential in glaucoma surgery, neuroprotection, and cosmetic procedures. CONCLUSIONS Bimatoprost has shown immense potential for addressing a wide range of therapeutic needs through various formulations and advancements. Promising future perspectives include the exploration of novel delivery systems such as contact lenses and microneedles to further enhance drug efficacy and patient comfort. Ongoing research and future perspectives continue to shape its role in medicine, promising further advancements and improved patient outcomes.

Boubertakh B, Courtemanche O, Marsolais D, Di Marzo V, Silvestri C. New role for the anandamide metabolite prostaglandin F 2α ethanolamide: Rolling preadipocyte proliferation. J Lipid Res 2023; 64:100444. [PMID: 37730163 PMCID: PMC10622703 DOI: 10.1016/j.jlr.2023.100444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 08/24/2023] [Accepted: 09/11/2023] [Indexed: 09/22/2023] Open
Abstract
White adipose tissue regulation is key to metabolic health, yet still perplexing. The chief endocannabinoid anandamide metabolite, prostaglandin F2α ethanolamide (PGF2αEA), inhibits adipogenesis, that is, the formation of mature adipocytes. We observed that adipocyte progenitor cells-preadipocytes-following treatment with PGF2αEA yielded larger pellet sizes. Thus, we hypothesized that PGF2αEA might augment preadipocyte proliferation. Cell viability MTT and crystal violet assays, cell counting, and 5-bromo-2'-deoxyuridine incorporation in cell proliferation ELISA analyses confirmed our prediction. Additionally, we discovered that PGF2αEA promotes cell cycle progression through suppression of the expression of cell cycle inhibitors, p21 and p27, as shown by flow cytometry and qPCR. Enticingly, concentrations of this compound that showed no visible effect on cell proliferation or basal transcriptional activity of peroxisome proliferator-activated receptor gamma could, in contrast, reverse the anti-proliferative and peroxisome proliferator-activated receptor gamma-transcription activating effects of rosiglitazone (Rosi). MTT and luciferase reporter examinations supported this finding. The PGF2αEA pharmaceutical analog, bimatoprost, was also investigated and showed very similar effects. Importantly, we suggest the implication of the mitogen-activated protein kinase pathway in these effects, as they were blocked by the selective mitogen-activated protein kinase kinase inhibitor, PD98059. We propose that PGF2αEA is a pivotal regulator of white adipose tissue plasticity, acting as a regulator of the preadipocyte pool in adipose tissue.

Abstract
PRCIS Although Omidenepag isopropyl drops elicited stable intraocular pressure reductions in NTG patients, transient changes in refraction and corneal endothelial cells, significant increase of central corneal thickness, and corneal erosion should be considered. PURPOSE To analyze the efficacy and safety of 0.002% omidenepag Isopropyl (OMDI) eye drops in patients with normal tension glaucoma (NTG). METHODS Medical records for 62 eyes treated with OMDI for ≥6 months were analyzed. Intraocular pressure (IOP), refraction, keratometry, central corneal thickness (CCT), endothelial cell count, coefficient of variation of endothelial cell area (CV), corneal erosion, and central retinal thickness were compared at baseline and 1, 3, and 6 months. RESULTS IOP significantly decreased from 13.4±3.8 to 11.9±3.0, 11.7±2.9, and 12.2±3.3 mm Hg at each follow-up ( P <0.001). Endothelial cell count did not change, but CV transiently increased from 12.6 to 17.0 at 1 month, CCT increased from 531.5 to 538.4 μm, myopia changed from -1.5 to -1.9 D, and keratometry changed from 44.5 to 44.7 D. CV, myopia, and keratometry recovered to baseline at 6 months; however, CCT remained high. Significant corneal erosion was observed at 6 months. Central retinal thickness changes were not observed. There were improvements in prostaglandin-associated skin pigmentation (86.7%), eyelash elongation (40.0%), and deepening of the upper eyelid sulcus and ptosis (~30%) at 3 months after exchange to OMDI. Adverse reactions were corneal erosion (27.4%), corneal thickening (21.0%), conjunctival hyperemia (11.3%), photophobia (5.7%), blurred vision (5.7%), and anterior chamber cells (4.8%). CONCLUSIONS OMDI eye drops elicited significant and stable IOP reductions after 6 months in NTG patients with low IOP. However, transient myopic and corneal endothelial cell changes, development of corneal thickening, and corneal erosion should be considered when using OMDI.

Prostaglandin-Associated Periorbitopathy Symptom Alleviation After Switching Prostaglandin F Receptor Agonist to EP2 Receptor Agonist in Patients with Glaucoma. J Ocul Pharmacol Ther 2023; 39:63-69. [PMID: 36318495 DOI: 10.1089/jop.2022.0096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/05/2022] Open
Abstract
Purpose: Prostaglandin-associated periorbitopathy in patients with glaucoma is reportedly not caused by EP2 agonist, but it has been a cosmetic problem with prostaglandin F receptor (FP) agonists. In this study, patients with prostaglandin-associated periorbitopathy on FP agonists were switched to EP2 agonist and changes were investigated. Methods: Patients complaining of prostaglandin-associated periorbitopathy were included. The FP agonist was switched to EP2 agonist (omidenepag isopropyl), and patients were followed up for 7 months. Frontal photographs were taken at every visit, and objective changes in deepening of the upper eyelid sulcus were assessed by three observers. Subjective questionnaires (self-awareness of deepening of the upper eyelid sulcus, eyelid/peri-eyelid skin pigmentation, eyelash elongation, and conjunctival hyperemia) were acquired at the start and the endpoint. Factors associated with the change of prostaglandin-associated periorbitopathy were investigated using logistic regression analysis. Results: Included were 23 eyes of 23 patients (17 women; 60.6 years). At 7 months, objective deepening of the upper eyelid sulcus improved by 76%. The subjective questionnaires showed that deepening of the upper eyelid sulcus improved in 95%, eyelid/peri-eyelid skin pigmentation in 76%. The less extent of myopia was a significant factor in the eyes with improved eyelid/peri-eyelid skin pigmentation. After switching, no change in intraocular pressure or visual acuity was observed (P ≥ 0.22). Conclusion: Switching to omidenepag isopropyl increased patient satisfaction and might be the first step to lightening deepening of the upper eyelid sulcus and eyelid/peri-eyelid skin pigmentation. It was suggested that pigmentation may be more easily improved in nonmyopic eyes.

Prostaglandins Leukot Essent Fatty Acids 2022; 187:102511.

Abstract
Bimatoprost is a synthetic prostamide F2α analog that down-regulates adipogenesis in vitro. This effect has been attributed to participation in a negative feedback loop that regulates anandamide-induced adipogenesis. A follow-on investigation has now been conducted into the broader metabolic effects of bimatoprost using rats under both normal state and obesity-inducing conditions. Chronic bimatoprost administration attenuated weight gain in a dose dependent-manner in rats fed either standard [max effect -7%] or obesity-promoting diets [max effect -23%] over a 9-10 week period. Consistent with these findings, bimatoprost promoted satiety as measured by decreased food intake [max effect, -7%], gastric emptying [max effect, -33-50%] and decreased circulating concentrations of the gut hormones, ghrelin and GLP-1 [max effect, -33-50%]. Additionally, subcutaneous, and visceral fat mass were distinctly affected by treatment [-30% diet independent]. Taken together, these results suggest that bimatoprost regulates energy homeostasis through promoting satiety and a decrease in food intake. These newly reported activities of bimatoprost reveal an additional method of metabolic disease intervention for potential therapeutic exploitation.

Addition of ROCK Inhibitors Alleviates Prostaglandin-Induced Inhibition of Adipogenesis in 3T3L-1 Spheroids. Bioengineering (Basel) 2022; 9:bioengineering9110702. [DOI: 10.3390/bioengineering9110702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 11/05/2022] [Accepted: 11/07/2022] [Indexed: 11/19/2022] Open
Abstract
To elucidate the additive effects of the ROCK inhibitors (ROCK-i), ripasudil (Rip) and Y27632 on bimatoprost acid (BIM-A), a prostaglandin analog (PG), on adipose tissue, two- and three-dimensional (2D or 3D) cultures of 3T3-L1 cells, the most well characterized cells in the field of lipid research, were used. The cells were subjected to a variety of analyses including lipid staining, real-time cellular metabolic analysis, the mRNA expressions of genes related to adipogenesis and extracellular matrices (ECMs) as well as the sizes and physical properties of the 3D spheroids by a micro-squeezer. BIM-A induced strong inhibitory effects on most of the adipogenesis-related changes in the 2D and 3D cultured 3T3-L1 cells, including (1) the enlargement and softening of the 3D spheroids, (2) a dramatic enhancement in lipid staining and the expression of adipogenesis-related genes, and (3) a decrease in mitochondrial and glycolytic metabolic function. By adding ROCK-i to the BIM-A, most of these BIM-A-induced effects were cancelled. The collective findings reported herein suggest that ROCK-i eliminated the PG-induced suppression of adipogenesis in the 3T3-L1 cells, accompanied by the formation of enlarged 3D spheroids. Such effects of adding ROCK-i to a PG in preadipocytes on cellular properties appear to be associated with the suppression of PG-induced adverse effects, and provide additional insight into our understanding of lipid-related research.

Brimonidine Modulates the ROCK1 Signaling Effects on Adipogenic Differentiation in 2D and 3D 3T3-L1 Cells. Bioengineering (Basel) 2022; 9:bioengineering9070327.

Abstract
The additive effects of an α2-adrenergic agonist, brimonidine (BRI), on the pan-ROCK inhibitor (ROCK-i), ripasudil (Rip), and the ROCK2-I, KD025, on adipogenic differentiation (DIF+) were examined using two- or three-dimension (2D or 3D) cultures of 3T3-L1 cells. The following analyses were carried out: (1) lipid staining (2D and 3D), (2) real-time measurements of cellular metabolism (2D), (3) mRNA expression of DIF+ related genes and extracellular matrix molecules (ECMs) including collagen (Col)-1, -4, and -6, and fibronectin (Fn), and (4) the sizes and physical properties of the 3D spheroids. The findings indicate that DIF+ induced (1) a substantial enhancement in lipid staining and enhanced expression of the Pparγ and Fabp4 genes, (2) significantly larger and softer 3D spheroids, and (3) down-regulation of Col1 and Fn and up-regulation of Col4 and Col6 genes. Treatment with Rip alone caused a significant enhancement in adipogenesis of both the 2D and 3D cultured 3T3-L1 cells and in the physical properties of the 3D spheroids; these effects were substantially inhibited by BRI, and the effects induced by BRI or KD025 were not insignificant. These collective findings indicate that the addition of BRI inhibited the Rip-induced enhancement of DIF+ in 3T3-L1 cells, presumably by modulating ROCK1 signaling.

Abstract
Many patients are treated for glaucoma. Like other drugs, anti-glaucoma eye drops may induce dermatological adverse effects. We aim to review the dermatological adverse effects secondary to the active agents in anti-glaucoma eye drops through a literature review. In January 2020, we queried PubMed using the following MeSH terms: glaucoma/drug therapy or glaucoma, open angle/drug therapy cross-referenced with parasympathomimetics/adverse effects or adrenergic agonists/adverse effects or carbonic anhydrase inhibitors/adverse effects or prostaglandins F, synthetic/adverse effects or adrenergic beta antagonists/adverse effects or ophthalmic solutions/adverse effects. The initial search identified 1128 studies, of which 49 were excluded for being in a foreign language, 15 for not involving eye drops, 968 for not focusing on adverse dermatological effects, and 11 for insufficient documentation or redundancy. After adding 38 linked studies, we finally analysed 123 studies. The ocular and periocular dermatological adverse effects of eye drops are contact dermatitis, hyperpigmentation, prostaglandin analogue periorbitopathy, mucous membrane pemphigoid, eyelash depigmentation, skin hypertrichosis, and rare cases of melanoma and skin depigmentation. The reported distant dermatological adverse effects are psoriasis, excessive sweating, lichen planus, alopecia, toxic epidermal necrolysis, erythema multiforme, erythroderma, subacute cutaneous lupus erythematosus, nail pigmentation and bullous pemphigoid. Most of the cutaneous adverse effects of anti-glaucoma eye drops are ocular and periocular and induced by prostaglandin analogues. Distant adverse effects are rare and sometimes questionable but should be kept in mind, especially mucous membrane pemphigoid, which could lead to blindness. The role of preservatives, such as benzalkonium chloride, should also be considered.

Abstract
To elucidate the effects of switching a PGF2α agonist, bimatoprost acid (BIM-A), to an EP2 agonist (Omidenepag—OMD; butaprost—Buta) or reversing the switching on adipose tissue, two-dimensional (2D) and three-dimensional (3D) cultures of 3T3-L1 cells were analyzed by lipid staining and according to the mRNA expression of adipogenesis-related genes (Pparγ, Ap2, and Leptin), components of the extracellular matrix (ECM; collagen1 (Col1), Col4, Col6, and fibronectin (Fn)), and the sizes and stiffness of the 3D spheroids. Switching from BIM-A to EP2 agonists caused (1) suppression of lipid staining and downregulation of most adipogenesis-related genes, (2) smaller and stiffer 3D spheroids, and (3) upregulation of Col1 and Fn, downregulation of Col4 (2D), or up-regulation of all ECM genes (3D, BIM-A to OMD), as well as downregulation of Col6 (3D, BIM-A to Buta). In contrast, reversing the switching resulted in (1) an enhancement in lipid staining (2D) and a significant upregulation of adipogenesis-related genes (2D, 3D Buta to BIM-A), (2) larger and slightly stiffer 3D spheroids, and (3) upregulation of Col1 and Fn (2D). These collective findings indicate that the switching orders of BIM-A and EP2 agonists have a significant effect on lipid metabolism, ECM expression, and the physical stiffness of 3T3-L1 cells.

Abstract
INTRODUCTION In the last 25 years, topical prostaglandin analogues (PGAs) have emerged to become first line and first choice therapeutic options in the management of glaucoma and ocular hypertension (OHT). Although the short-term efficacy and safety of PGAs has been extensively investigated, less is known about their long term safety and tolerability. This gap in current knowledge is clinically relevant, because treatment-related adverse events and long-term tolerability issues are key determinants of the overall success of long-term therapy and the final outcome of a lifelong, symptomless disease like glaucoma. AREAS COVERED We include selected evidence pertaining to the safety and tolerability of available and emerging PGA formulations. We also outline PGA formulations with different concentrations of the active ingredient, different preservatives, and preservative-free (PF) options. EXPERT OPINION Undoubtedly PGAs will continue to play a major role in the medical therapy of glaucoma and OHT. Despite extensive literature and prolonged clinical experience with these agents worldwide, a number of areas that warrant further research have been identified in the present review. Recently launched novel PGAs, or those still in development offer new opportunities and future challenges.

Abstract
The distribution of prostaglandin-associated periorbitopathy (PAP) graded using the Shimane University PAP Grading System (SU-PAP) among glaucoma/ocular hypertension subjects using a topical FP or EP2 receptor agonist was reported. A 460 consecutive 460 Japanese subjects (211 men, 249 women; mean age ± standard deviation, 69.9 ± 14.5 years) who had used either a FP agonist (0.005% latanoprost, 0.0015% tafluprost, 0.004% travoprost, 0.03% bimatoprost, or fixed combinations of these) or EP2-agonist (0.002% omidenepag isopropyl) for more than 3 months in at least 1 eye were retrospectively enrolled. Age, sex, prostaglandin, intraocular pressure (IOP) measured by Goldmann applanation tonometry (IOPGAT) and iCare rebound tonometry (IOPRBT), difference between IOPGAT and IOPRBT (IOPGAT-RBT), PAP grade, and PAP grading items were compared among groups stratified by PAP grade or prostaglandins. Of the study patients, 114 (25%) had grade 0 (no PAP), 174 (38%) grade 1 (superficial cosmetic PAP), 141 (31%) grade 2 (deep cosmetic PAP), and 31 (7%) grade 3 (tonometric PAP). The IOPGAT was significantly higher in grade 3 (17.5 ± 5.4 mm Hg) than grades 0 (15.0 ± 5.1 mm Hg, P = .032) and 1 (14.5 ± 4.2 mm Hg, P = .008), and the IOPGAT-RBT was significantly higher in grade 3 (5.8 ± 3.2 mm Hg) than the other 3 grades (1.3-1.9 mm Hg, P < .001 for all comparisons); the IOPRBT was equivalent among the 4 grades. The PAP grade was significantly higher associated with travoprost (2.0 ± 0.8) and bimatoprost (2.0 ± 0.7) than latanoprost (1.0 ± 0.8, P < .001 for both comparisons) and tafluprost (1.0 ± 0.7, P < .001 for both comparisons), but significantly lower associated with omidenepag (0.0 ± 0.0, P < .001 for all comparisons) than the other 4 prostaglandins. Multivariate analyses showed older age (standard β = 0.11), travoprost (0.53, referenced by latanoprost) and bimatoprost (0.65) were associated with higher PAP grades, while tafluprost (-0.18) and omidenepag (-0.73) were associated with lower PAP grades. The PAP graded using SU-PAP reflects the degree of overestimation of the IOPGAT and different severities of PAP among the different prostaglandins. SU-PAP, the grade system constructed based on the underlining mechanisms of PAP, is a simple grading system for PAP that is feasible for use in a real-world clinical situation.

Abstract
PURPOSE To examine the effect of switching from a prostanoid FP receptor agonists to EP2 receptor agonist (omidenepag isopropyl) on the deepening of the upper eyelid sulcus (DUES) and intraocular pressure (IOP) in Japanese glaucoma patients over 3 months post treatment. STUDY DESIGN Prospective observational study. METHODS Patients with glaucoma who received FP receptor agonists treatment and had complained of DUES-related reduction in quality of life were included. Their FP receptor agonists was switched to omidenepag isopropyl without a drug holiday. At baseline and 1 and 3 months post-switch, photographs were taken and the changes in DUES were assessed by three independent observers. IOP and adverse events were also assessed. RESULTS The study included 23 eyes of 23 patients (6 men, 17 women; average age, 60.6 years). After switching, DUES improved in 12 eyes at 1 month and in 16 eyes at 3 months; eyes in the remaining patients showed no worsening of the condition. The mean IOP before switching was 15.3 ± 3.3 mmHg (95% confidence interval 13.9-16.7 mmHg). Following the switch, the mean IOP values were 15.6 ± 3.3 mmHg (14.1-17.0 mmHg) at 1 month and 15.5 ± 3.3 mmHg (14.1-16.9 mmHg) at 3 months (P = 1.0 at 1 month, P = 1.0 at 3 months; both adjusted by Bonferroni correction). No adverse effects were observed. CONCLUSION Omidenepag isopropyl improved DUES while maintaining IOP in over 70% of Japanese patients with glaucoma who exhibited DUES caused by FP receptor agonists; the improvement was observed within 3 months after switching from FP receptor agonists.

Abstract
Intraocular pressure reduction is the only available and evidence-based medical therapy for glaucoma. Currently, the first-line eye drops are prostaglandin analogues including latanoprost, travoprost, bimatoprost, and tafluprost. These drugs stimulate intraocular prostanoid false positive (FP) receptors and reduce intraocular pressure by increasing mainly uveoscleral aqueous outflow. For 2 decades since latanoprost was launched, no drug has been comparable in its efficacy. In 2018, a prostanoid EP2 agonist, omidenepag, was launched in Japan. Current FP agonists and EP2 agonists indicate comparable intraocular pressure reduction by stimulating prostanoid FP or EP2 receptors. However, their safety profiles are quite different because of the differences between the intracellular signaling pathways through their own receptors. Including these commercially available FP and EP2 receptor agonists, prostanoid receptors have a large potential to control intraocular pressure. In this review I will trace the history and development of FP and EP2 receptor agonists from their original function, and explain their potential as first-line drugs including elucidation of their efficacy and safety.

Abstract
Purpose The purpose of this study was to present the effects of the prostanoid EP2 agonist, omidenepag (OMD) on human orbital fibroblasts (HOFs) using a three-dimension (3D) cell culture. Methods During adipogenesis of 3D HOFs organoids, changes in size, lipids staining, mRNA expression of adipogenesis related genes, PPARγ, AP2, and ADIPOQ, and extracellular matrix, collagen 1 (COL 1), COL 4, COL 6, and fibronectin (FN), and stiffness by a micro-squeezer were examined in the presence and absence of either 100 nM bimatoprost acid (BIM-A) or 10, 100, or 10,000 nM OMD. Results The size of the 3D organoids increased dramatically during adipogenesis, and these were further enhanced in the presence of OMD in contrast to the BIM-A induced suppression effect. The intensity of lipid staining and the mRNA expression of PPARγ were significantly increased upon adipogenesis, and both or latter was markedly inhibited in the presence of OMD or BIM-A, respectively. AP2 expression was also upregulated by adipogenesis, and was further enhanced by BIM-A. The adipogenesis-induced downregulation of COL 1 and FN, or the upregulation of the expression of COL 4 and COL 6 were all suppressed in the presence of BIM-A. In contrast, OMD caused similar effects on COL 4, COL 6, or FN expression, but caused a significant increase in COL 1 expression. Stiffness was significantly increased upon adipogenesis, and was further increased or substantially decreased by BIM-A or OMD, respectively. Conclusions The present study indicates that the FP2 agonist, OMD, had different effects on 3D HOFs organoids, as compared to BIM-A. Translational Relevance The current study suggests that OMD may not induce deepening of upper eyelid sulcus (DUES).

Prostaglandin F2α agonists induced enhancement in collagen1 expression is involved in the pathogenesis of the deepening of upper eyelid sulcus. Sci Rep 2021; 11:9002. [PMID: 33903711 PMCID: PMC8076191 DOI: 10.1038/s41598-021-88562-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Accepted: 04/14/2021] [Indexed: 12/17/2022] Open
Abstract
Previous our study reported that three-dimension (3D) cultures of human orbital fibroblasts (HOFs) replicated the etiology of deepening of the upper eyelid sulcus (DUES) caused by prostaglandin F2α analogues (PGF2α-ags). To examine this further, the effects of PGF2α-ags on HOFs were characterized by (1) lipid staining (2D; two-dimension, 3D), (2) comparison of the 3D organoid sizes of preadipocytes (DIF-) or adipocytes (DIF+) that had been treated with various concentrations of several PGF2α-ags, (3) physical stiffness (3D), and (4) the mRNA expression of adipogenic related genes, extracellular matrix (ECM), tissue inhibitors of metalloproteinases (TIMPs) and matrix metalloproteinases (MMPs) (3D). PGF2α-ags caused a dramatic down-sizing of the 3D DIF+ organoids and this reduction was concentration dependent. The effects caused by PGF2α-ags were also observed in 3D preadipocytes. Micro-squeezer analysis clearly indicated that PGF2α-ags induced an increase in their physical solidity. The size of each organoid under several conditions was inversely correlated with the mRNA expression profile of collagen1 (COL1), TIMP2, and MMP2 and 9. These findings indicate that PGF2α-ags affect the expression of COL1, TIMP2, and MMP2 and 9 which, in turn, modulate the 3D ECM network within the organoids, thus resulting in their downsizing.

Prostaglandin F2α and EP2 agonists, and a ROCK inhibitor modulate the formation of 3D organoids of Grave's orbitopathy related human orbital fibroblasts. Exp Eye Res 2021; 205:108489.

Abstract
3D organoid cultures were used to elucidate the periocular effects of several anti-glaucoma drugs including a prostaglandin F2α analogue (bimatoprost acid; BIM-A), EP2 agonist (omidenepag; OMD) or a Rho-associated coiled-coil containing protein kinase (ROCK) inhibitor (ripasudil; Rip) on Grave's orbitopathy (GO) related orbital fatty tissue. 3D organoids were prepared from GO related human orbital fibroblasts (GHOFs) obtained from patients with GO. The effects of either 100 nM BIM-A, 100 nM OMD or 10 μM Rip on the 3D GHOFs organoids were examined with respect to organoid size, physical properties by a micro-squeezer, and the mRNA expression of extracellular matrix (ECM) proteins including collagen (COL) 1, COL 4, COL 6, and fibronectin (FN), ECM regulatory genes including lysyl oxidase (LOX), Connective Tissue Growth Factor (CTGF) and inflammatory cytokines including interleukin-1β (IL1β) and interleukin-6 (IL6). The size of the 3D GHOFs organoids decreased substantially in the presence of BIM-A, but also increased substantially in the presence of the others (OMD or Rip). The physical stiffness of the 3D GHOFs organoids was significantly decreased by Rip. BIM-A caused significantly the down-regulation of three ECM genes, Col 1, Col 6 and Fn, and two ECM regulatory genes and the up-regulation of IL6. In the presence of OMD, two ECM genes, Col 1 and Fn, and LOX were significantly down-regulated but IL1β and IL6 were significantly up-regulated. In the case of Rip, Col 1, FN and CTGF were significant down-regulated. Our present findings indicate that anti-glaucoma drugs modulate the structures and physical properties 3D GHOFs organoids in different manners by modifying the gene expressions of ECM, ECM regulatory factors and inflammatory cytokines. The results indicate that the benefits and demerits of anti-glaucoma medications need to be scrutinized carefully, in cases of patients with GO.

Abstract
Purpose To elucidate the molecular etiology of deepening of the upper eyelid sulcus (DUES) induced by prostaglandin (PG) analogs, a three-dimensional (3D) tissue culture system was employed using human orbital fibroblasts (HOFs). Methods During adipogenesis, changes in HOF 3D organoid sizes, as well as their lipids stained by BODIPY and expression of the extracellular matrix (ECM) by immunolabeling and/or quantitative PCR, were studied in the presence or absence of either 100-nM bimatoprost acid or 100-nM prostaglandin F2α. Results The size of the 3D organoids increased remarkably during adipogenesis, but such increases were significantly inhibited by the presence of PG analogs. Staining intensities by BODIPY and mRNA expression of peroxisome proliferator-activated receptor gamma were significantly increased upon adipogenesis but were not influenced by the presence of PG analogs. Unique changes in ECM expression observed with or without adipogenic differentiation were significantly modified by the presence of PG analogs. Conclusions Our present study indicates that PG analogs have the potential to modulate the ECM network within HOF 3D organoids. Thus, a 3D tissue culture system may be a suitable strategy for understanding the disease etiology of DUES.

Abstract
OBJECTIVE To evaluate for relative palpebral and orbital changes after long-term unilateral exposure to prostaglandin analogues (PGAs) in patients with childhood glaucoma. DESIGN Prospective cross-sectional cohort study. PARTICIPANTS A total of 29 patients with history of childhood glaucoma, who were treated unilaterally with PGAs for at least 12 months. METHODS Based on 4 standardized clinical photographs (en face with eyes open, right and left side views with eyes open, and en face with eyes closed), 3 masked expert graders each independently selected the eye they perceived to have received unilateral PGA treatment by physical appearance alone and graded the following features relative to the other eye: (1) ocular (e.g., conjunctival hyperemia, iris heterochromia, and buphthalmos), (2) palpebral (e.g., eyelash trichomegaly, eyelash hypertrichosis, eyelid erythema, eyelid edema, eyelid hyperpigmentation, high upper eyelid crease, upper eyelid ptosis, upper and/or lower eyelid retraction, and eyelid skin atrophy with presence of telangiectasias), and (3) periorbital (e.g., superior sulcus hollowing, proptosis, enophthalmos, hypoglobus, and hyperglobus). An interrater reliability analysis was performed using the Fleiss kappa (κ) statistic to determine consistency among raters. MAIN OUTCOME MEASURES Frequencies of each feature of prostaglandin-associated periorbitopathy (PAP); group consensus; interrater reliability of selected PGA-treatment laterality. RESULTS Median unilateral PGA exposure time was 31.7 months (interquartile range: 18.8-44.3 months). Eyelash trichomegaly and hypertrichosis (n = 22, 76%), high upper eyelid crease (n = 20, 69%), upper eyelid ptosis (n = 14, 52%), and superior sulcus hollowing (n = 15, 52%) were the most frequently observed features of PAP in PGA-treated eyes compared with untreated fellow eyes. Most of these changes were mild, but 20% to 30% of patients exhibited moderate eyelash and/or eyelid changes. One patient had severe PAP after long-term unilateral PGA exposure. Group consensus with correctly selected laterality was achieved in all patients. The inter-rater reliability was excellent (κ = 0.815, P < 0.001, 95% confidence interval [0.605, 1.000]). CONCLUSIONS Mild-to-moderate changes in the ocular adnexa can develop in children and young adults with long-term PGA exposure. Patients and their families should be educated on the possibility of PAP, especially when initiating monocular PGA therapy.

Abstract
2D and 3D cultures of 3T3-L1 cells were employed in a study of the effects of Omidenepag (OMD), interacting with a non-prostanoid EP2 receptor, on adipogenesis. Upon adipogenesis, the effects on lipid staining, the mRNA expression of adipogenesis-related genes (Pparγ, CEBPa, Ap2, and Glut4) and the extracellular matrix (ECM) including collagen type 1, 4 and 6, and fibronectin, and the size and physical property of 3D organoids were compared between groups that had been treated with EP2 agonists (butaprost and OMD) and PGF2α. Upon adipogenesis, these significantly suppressed lipid staining and the mRNA expression of related genes. EP2 agonists and PGF2α influenced the mRNA expression of ECM in different manners, and these effects were also different between 2 and 3D cultures. Examining the physical properties by a microsqueezer indicated that the solidity of the 3D organoids became significantly lowered upon adipogenesis and these effects were not affected by EP2 agonists. In contrast, 3D organoid stiffness was markedly enhanced by the presence of PGF2α. These observations indicate that EP2 agonists affect the adipogenesis of 3T3-L1 cells in different manners, as compared to PGF2α, suggesting that OMD may not induce PGF2α related orbital fat atrophy, called the deepening of the upper eyelid sulcus (DUES).

Abstract
Purpose Topical prostaglandin analogs (PGAs) are common treatment for primary open-angle glaucoma (POAG) but reportedly may cause adnexal fat atrophy. We asked if patients with POAG treated with PGAs have abnormalities in orbital fat volume (OFV). Methods We studied 23 subjects with POAG who had never experienced intraocular pressure (IOP) exceeding 21 mm Hg and were treated long term with PGAs, in comparison with 21 age-matched controls. Orbital volume, non-fat orbital tissue volume, and OFV were measured using high-resolution magnetic resonance imaging. Results Subjects with POAG had been treated with PGAs for 39 ± 19 months (SD) and were all treated within the 4 months preceding study. In the region from trochlea to orbital apex, OFV in POAG was significantly less at 9.8 ± 1.9 mL than in the control subjects at 11.1 ± 1.3 mL (P = 0.019). However, between the globe-optic nerve junction (GONJ) and trochlea, OFV was similar in both groups. Width and cross sectional area of the bony orbit were significantly smaller in POAG than in controls (P < 0.0001). Posterior to the GONJ, the average orbital cross-sectional area was 68.2 mm2 smaller, and the orbital width averaged 1.5 mm smaller throughout the orbit, in patients with POAG than in controls. Conclusions Patients with POAG who have been treated with PGAs have lower overall OFV than controls, but OFV in the anterior orbit is similar in both groups. Lower overall OFV in POAG may be a primary association of this disorder with a horizontally narrower bony orbit, which may be a risk factor for POAG at nonelevated IOPs.

Abstract
Purpose To qualitatively evaluate the ocular and periocular distribution of 14C-latanoprost following a single intracameral administration or repeated topical ocular administration in beagle dogs and cynomolgus monkeys. Methods In the dog study, three animals received an intracameral dose of 14C-latanoprost bilaterally and were euthanized at 1, 2, and 4 h post dose; three control animals received topical 14C-latanoprost bilaterally once daily for 5 days and were euthanized at 1, 4, and 24 h post final dose. Sagittal 40-µm sections of eyes with surrounding tissues were collected and processed for autoradiography. Methods in the monkey study were similar; two animals received a unilateral intracameral dose of 14C-latanoprost. Results After intracameral dosing in dogs, radioactivity was concentrated in the cornea, iris, ciliary body, and anterior chamber with no radioactivity detected in the eyelids or other periorbital tissues. After topical dosing, radioactivity was distributed in the bulbar conjunctiva, cornea, anterior chamber, iris, ciliary body, upper and lower eyelids, and periorbital tissues (fat/muscle). After intracameral dosing in monkeys, radioactivity was concentrated in the anterior chamber, cornea, iris, ciliary body, and posteriorly along the uveoscleral outflow pathway; there was no radioactivity in the eyelids or periorbital tissues aside from signal in the nasolacrimal duct, likely from reflux of 14C-latanoprost into the tear film. Conclusions Intracameral delivery resulted in more selective target tissue drug exposure. Intracameral drug delivery has potential to reduce ocular surface and periocular adverse effects associated with topical administration of prostaglandin analogues, such as eyelash growth and periorbital fat atrophy.

Abstract
To establish a deepening of the upper eyelid sulcus (DUES) model that can be induced by prostaglandin (PG) analogues, a three-dimension (3D) tissue culture was employed. Upon adipogenesis of the 3T3-L1 organoid, the effects of either Bimatoprost acid (BIM-A), or PGF2α were examined. During the adipogenesis, organoid size, lipid staining by BODIPY and expression of the extracellular matrix (ECM) by immunocytochemistry and/or quantitative PCR were employed. The size of the organoid increased remarkably during the adipogenesis, while such increases were significantly inhibited by the presence of PGF2α or BIM-A. BODIPY positive lipid-laden cells significantly increased during the adipogenesis, while in contrast they were greatly suppressed by the presence of PGF2α. Characteristic and spatial changes in ECM expressions observed upon adipogenesis were greatly modified by the presence of PGs. Our present study using a 3D tissue culture may be a suitable strategy toward understanding disease etiology of DUES.

Abstract
BACKGROUND Eyebrow hypotrichosis is an important dermatological problem. However, there is no standard treatment. OBJECTIVE To study the efficacy and safety of bimatoprost 0.01% for the treatment of eyebrow hypotrichosis. MATERIALS AND METHODS Although bimatoprost 0.03% has been studied previously, this is the first study to evaluate the efficacy and safety of bimatoprost 0.01% for the treatment of eyebrow hypotrichosis. A randomized, double-blinded, vehicle-controlled trial was conducted in 40 patients. All patients were randomized to receive bimatoprost 0.01% or placebo vehicle, once daily, for 6 months. The primary outcome was improvement in eyebrow density and diameter. Additional outcomes were the improvement in clinical assessments and safety evaluation. RESULTS Compared to the vehicle group, bimatoprost 0.01% significantly increased mean eyebrow hair density, eyebrow hair diameter, and clinical assessments (p < .001) in the drug group. Patients' satisfaction score was higher for the drug group than the vehicle group (p < .05). Adverse effects of the treatment were minimal and similar between the 2 groups. CONCLUSION Bimatoprost 0.01% was found to be superior to a placebo for eyebrow enhancement. Bimatoprost 0.01% can be considered effective, safe, and well-tolerated for the treatment of eyebrow hypotrichosis.

Optic Nerve Traction During Adduction in Open Angle Glaucoma with Normal versus Elevated Intraocular Pressure. Curr Eye Res 2020; 45:199-210. [PMID: 31453714 PMCID: PMC7398593 DOI: 10.1080/02713683.2019.1660371] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 08/05/2019] [Accepted: 08/21/2019] [Indexed: 12/15/2022]
Abstract
Purpose/Aim: We used magnetic resonance imaging (MRI) to investigate effects of intraocular pressure (IOP), race, and other factors on optic nerve (ON) traction in adduction, a phenomenon proposed as neuropathic in open angle glaucoma (OAG).Materials and Methods: Thirty-five patients with OAG (26 with maximal untreated IOP ≤21 mmHg, 9 with IOP >21mmHg) and 48 controls underwent axial and quasi-coronal MRI in central gaze and large (27-33°) abduction and adduction. Some underwent MRI at smaller ductions (21-28°). Effects of presence vs. absence of OAG; within OAG whether maximum IOP level was ≤21 mmHg vs. >21 mmHg; adduction angle; race; age; and gender on ON path length and globe translation were analyzed using generalized estimating equations to account for possible intereye correlations of individual subjects.Results: Average visual field mean deviation (±standard error of mean, SEM) was -8.2 ± 1.2 dB in OAG with normal IOP, and -6.1 ± 1.4 in high IOP. In central gaze, ON path in OAG was significantly more redundant than in controls but in both groups the ON became significantly and almost equally straighter in small (~21°) or large (~27°) adduction than in central gaze. With progressive adduction only, globes retracted in OAG (P < 0.005) but not in controls; this was only weakly related to globe size and not to IOP elevation. Globe retraction in adduction was significant only in OAG, and in that group was significantly greater in Asian than white patients (P < 0.02).Conclusions: Although ON tethering in adduction is normal, progressive adduction is associated with abnormal globe retraction in OAG regardless of IOP level. This phenomenon is more prominent in Asians who have OAG. Traction in adduction may cause repetitive strain injury to the ON and peripapillary sclera, thus contributing to the optic neuropathy of glaucoma independent of IOP.

Am J Ophthalmol 2019; 206:11-16. [PMID: 30902695 DOI: 10.1016/j.ajo.2019.03.013] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Revised: 03/07/2019] [Accepted: 03/07/2019] [Indexed: 11/30/2022]
Abstract
PURPOSE To investigate changes in the interpupillary distance (IPD) after continual instillation of topical prostaglandin analogs (PGAs) in glaucoma patients as an objective indicator of prostaglandin-associated periorbitopathy (PAP). DESIGN Retrospective, comparative case series. METHODS A total of 152 institutional patients with glaucoma were enrolled in this study. Inclusion criteria were visual acuities exceeding 10/20 bilaterally and no intraocular surgery during observation. Intervention/observation procedures: First-time bilateral instillation of bimatoprost, travoprost, latanoprost, or tafluprost and IPDs measured by automatic refractometry. IPDs, intraocular pressures (IOPs), and refractive errors were measured before and after continual drug administration (treatment, 2-24 months). MAIN OUTCOME MEASUREMENTS Post-treatment changes in IPDs. A total of 61 untreated patients served as controls. RESULTS The IPDs shortened significantly (P < 0.001) after treatment (-0.80 ± 2.1 mm); the IPDs of control subjects remained unchanged (0.05 ± 0.96 mm; P = 0.69). The IPD change after bimatoprost instillation (-2.20 ± 0.97 mm) was significantly (P < 0.001) greater than with other PGAs (-0.65 ± 2.09 mm). The IOPs decreased significantly (P < 0.001) (-3.7 ± 4.3 mm Hg); the refractive errors did not change significantly (P < 0.099) (-0.07 ± 0.69 diopter) post-treatment. The percentages of subjects with 2-mm or greater decreases in IPD after bimatoprost, travoprost, latanoprost, or tafluprost were 85.7%, 20.0%, 18.2%, and 17.2%, respectively, and with 3-mm or greater decreases in IPD 35.7%, 12.0%, 14.5%, and 12.1%, respectively. The specificities were 93.4% and 100% in the control group, respectively, with IPD threshold changes of 2 and 3 mm or more, respectively. CONCLUSIONS The IPD decreased significantly after topical PGAs within 24 months. The effect was significantly greater with bimatoprost than with other PGAs. The noninvasive, immediate automatic refractometry measurement may be an objective numerical indicator of PAP.

Abstract
We quantitatively determined the relation between the decrease in orbital fat and enophthalmos due to bimatoprost using magnetic resonance imaging (MRI). Nine orbits in nine patients were treated unilaterally with bimatoprost for glaucoma or ocular hypertension. The contralateral orbits were used as controls. The volumes of the orbital tissues and the enophthalmos were measured using MRI. The mean volumes on the treated and untreated sides were, respectively, 14.6 ± 2.1 and 17.0 ± 4.3 cm3 for orbital fat (P = 0.04) and 3.4 ± 0.5 and 3.3 ± 0.5 cm3 for total extraocular muscles (P = 0.85). The mean enophthalmos values were 14.7 ± 2.5 and 16.0 ± 2.3 mm on the treated and untreated sides, respectively (P = 0.002). The data acquired by quantitatively measuring the volumes of orbital fat and enophthalmos on MRI showed that each might be reduced by bimatoprost administration. The enophthalmos could be caused by the bimatoprost-induced decrease in orbital fat.

Abstract
Purpose This study was performed to observe changes prospectively in exophthalmos and orbital fat in patients with inactive thyroid-associated ophthalmopathy (TAO) treated with bimatoprost. Methods In this 12-month single-treatment pilot observational study, 13 patients with inactive-phase TAO were administered bimatoprost to treat exophthalmos due to TAO. Exophthalmos values and orbital tissue volumes were measured on MRI by technicians in a masked fashion. Results Nine orbits of nine patients (eight women, one man) were treated with bimatoprost for 12 months. Mean exophthalmos values before and after treatment were 21.7±2.2 and 21.7±2.0 mm, respectively. The mean value after 12 months of treatment was not significantly different from before treatment (P=0.82). Mean orbital fat volume before and after 12 months of treatment was 17.2±2.5 and 17.0±3.0 cm3, respectively. The corresponding total extraocular muscle volume was 4.0±0.7 and 3.8±0.9 cm3, respectively. Mean volume in each tissue type after 12 months of treatment was not significantly different from before treatment (orbital fat, P=0.70; extraocular muscles, P=0.32). Conclusion Topical bimatoprost treatment did not reduce exophthalmos or orbital fat in this cohort of patients with inactive TAO.

Abstract
The development of ophthalmic drug delivery systems is a long and comprehensive process including research, nonclinical, and clinical development stages. It is critical to understand the similarity and differences between animal models and patients. There are many anatomically and physiologically important parameters for targeted drug delivery into eyes. This paper reviews the constraints to various routes of ocular drug delivery and discusses the respective pharmacokinetic considerations, to lay the foundation for formulation approaches pharmaceutical scientists can use to maximize successful drug delivery for each route. The overall goal is to give both researchers and drug developers a better understanding of ocular drug delivery and offer tools to successfully develop new medicines that will fulfil unmet medical needs and improve patients' quality of life.

Abstract
Bimatoprost is a prostamide analogue used for treatment of glaucoma in ophthalmology. Surprisingly, the side effects such as increased pigmentation of eyelids and hypertrichosis in patients being treated with prostaglandin analogues for glaucoma have opened new areas of application in various dermatological disorders such as alopecia mainly affecting eyelashes, eyebrows, and vitiligo.

In Vivo 2018; 32:211-220. [PMID: 29475902 PMCID: PMC5905187 DOI: 10.21873/invivo.11227] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2017] [Revised: 01/04/2018] [Accepted: 01/08/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND/AIM Prostaglandin analogues (PGAs) are a first-line medical treatment for glaucoma because of their powerful intraocular pressure (IOP) lowering effect, few systemic side-effects (SEs), and the once daily administration. Despite the high systemic safety profile, the chronic use of PGAs may induce periocular and ocular surface (OS)-related side effects, which affect a significant proportion of glaucomatous patients. In this review, we summarize the current knowledge about SEs of PGAs on periocular structures and OS, and their implications in clinical practice. MATERIALS AND METHODS A comprehensive literature search on the PubMed platform was performed. Two hundred fifty articles fulfilling key words were identified, of which 180 were excluded since they did not concern the effects of PGAs on the periocular tissues and OS, or because of their limited relevance. The following key words were used and combined, to narrow-down the literature: "prostaglandin" and "ocular surface," which identified 184 unique publications, of which 68 were selected; "prostaglandin" and "periocular" which identified 46 unique publications, of which 11 were selected. An additional search was conducted using "prostaglandin" and "Meibomian glands (MGs)", which identified twenty unique publications, of which 8 were selected. Thus, a total of 70 articles were chosen based on their relevance and were included in this review. RESULTS Prostaglandin-associated peri-orbitopathy, skin pigmentation and hypertrichosis, eyelash growth, and MGs dysfunction are the most frequent modifications of periocular tissues. They are induced by the tissue accumulation of PGAs, and FP receptor stimulation. Without preservatives, PGAs act as stimulators of conjunctival goblet cells, which are the main source of ocular surface mucoproteins, and seem to increase conjunctival epithelium microcysts proposed as in vivo hallmark of the trans-scleral aqueous humour outflow. Additional PGA-induced modifications can be recognized in the cornea, corneo-scleral limbus, conjunctival stroma and, conjunctiva-associated lymphoid tissue, mainly appearing as inflammatory changes. OS epithelia desquamation, chemosis, apoptosis, dendritic cell activation, conjunctival or episcleral vasodilation, and sub-basal nerve plexus disruption were also described in patients receiving preserved PGAs. CONCLUSION PGAs induce several modifications of the OS structures and adnexa; nonetheless, none of them significantly reduces the local safety profile of this class of drugs. Moreover, the OS changes do not affect the IOP lowering efficacy of PGAs. On these bases, local SEs of PGAs should not discourage clinicians in using this class of medications because of their efficacy, the systemic safety profile, and the better adherence.

Changes in Sunken Eyes Combined with Blepharoptosis after Levator Resection. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2017; 5:e1616. [PMID: 29632789 PMCID: PMC5889433 DOI: 10.1097/gox.0000000000001616] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2017] [Accepted: 11/07/2017] [Indexed: 11/26/2022]
Abstract
Background: This study aims to report the changes in sunken eyes combined with blepharoptosis after levator resection. Methods: Analysis involved 60 eyes from 32 patients with sunken eyes combined with blepharoptosis. Advancement of the levator aponeurosis and the Müller’s muscle complex (levator resection) was performed in these patients. Area of upper eyelid sulcus (AES) was defined as the area of the upper eyelid shadow. The digital images were converted to black and white using image-processing software (Adobe Photoshop), and the AES was calculated using ImageJ software. In addition, margin reflex distance, eyebrow height (EBH), and AES were measured before and 3 months after surgery to assess the changes in the eyelids. Results: Preoperative AES was significantly correlated to age (P < 0.0001; r = 0.8062). Sunken eyes were remarkably improved after levator resection in all patients. Mean margin reflex distance significantly increased, whereas mean EBH and mean AES significantly decreased at 3 months after surgery (P < 0.0001). The AES change was significantly correlated to the EBH change (P < 0.0001; r = 0.5184). Conclusions: The principal aim of levator resection is to improve upper eyelid height and visual fields; however, this technique can alter the location of the eyebrow and upper orbital fat. The effects fill the hollowness of the upper eyelid and can remarkably improve sunken eyes.

Abstract
Purpose We used magnetic resonance imaging (MRI) to ascertain effects of optic nerve (ON) traction in adduction, a phenomenon proposed as neuropathic in primary open-angle glaucoma (POAG). Methods Seventeen patients with POAG and maximal IOP ≤ 20 mm Hg, and 31 controls underwent MRI in central gaze and 20° to 30° abduction and adduction. Optic nerve and sheath area centroids permitted computation of midorbital lengths versus minimum paths. Results Average mean deviation (±SEM) was −8.2 ± 1.2 dB in the 15 patients with POAG having interpretable perimetry. In central gaze, ON path length in POAG was significantly more redundant (104.5 ± 0.4% of geometric minimum) than in controls (102.9 ± 0.4%, P = 2.96 × 10−4). In both groups the ON became significantly straighter in adduction (28.6 ± 0.8° in POAG, 26.8 ± 1.1° in controls) than central gaze and abduction. In adduction, the ON in POAG straightened to 102.0% ± 0.2% of minimum path length versus 104.5% ± 0.4% in central gaze (P = 5.7 × 10−7), compared with controls who straightened to 101.6% ± 0.1% from 102.9% ± 0.3% in central gaze (P = 8.7 × 10−6); and globes retracted 0.73 ± 0.09 mm in POAG, but only 0.07 ± 0.08 mm in controls (P = 8.8 × 10−7). Both effects were confirmed in age-matched controls, and remained significant after correction for significant effects of age and axial globe length (P = 0.005). Conclusions Although tethering and elongation of ON and sheath are normal in adduction, adduction is associated with abnormally great globe retraction in POAG without elevated IOP. Traction in adduction may cause mechanical overloading of the ON head and peripapillary sclera, thus contributing to or resulting from the optic neuropathy of glaucoma independent of IOP.

Periorbital changes associated with prostaglandin analogs in Korean patients. BMC Ophthalmol 2017; 17:126. [PMID: 28716077 PMCID: PMC5514502 DOI: 10.1186/s12886-017-0521-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Accepted: 07/11/2017] [Indexed: 11/30/2022] Open
Abstract
Background Prostaglandin analogs (PGAs) are commonly used to treat glaucoma because of their powerful intraocular pressure lowering effect. However, various periorbital changes associated with the use of PGAs have been reported. We investigated the incidence of periorbital changes in Korean patients who were treated with PGAs, and analyzed clinical factors associated with superior sulcus deepening. Methods This study included 58 glaucoma patients who were treated with latanoprost, travoprost, or bimatoprost unilaterally. Face photographs were collected, and periorbital changes such as superior sulcus deepening, eyelid pigmentation, ptosis, lid retraction, dermatochalasis, and redness were evaluated by two oculoplastic specialists. For each patient, the contralateral eye served as a control. The frequency of ptosis, dermatochalasis, pigmentation, erythema, and superior sulcus deepening were analyzed. Demographic and ocular factors were compared between patients who showed superior sulcus deepening and those who did not. Results Thirty-one patients (53.4%) showed one or more periorbital changes associated with PGAs. The most common change was superior sulcus deepening (24.1%), followed by eyelid pigmentation (19.0%), eyelid erythema (19.0%), dermatochalasis (10.3%), eyelid retraction (5.2%), and ptosis (3.4%). The age of the patient and the duration of PGA administration was significantly correlated with superior sulcus deepening (p = 0.007, p = 0.002, respectively). Conclusions Periorbital changes are frequently seen in patients who use PGAs, and superior sulcus deepening is the most common change in Korean patients. Long-term use of PGAs and old age were associated with superior sulcus deepening.

Abstract
Prostaglandin F2α analogs, commonly prescribed for glaucoma treatment, have been shown to induce side effects such as cutaneous hypertrichosis and hyperpigmentation. Therefore, these medications have theoretic applications in the treatment of alopecia and disorders of hypopigmentation. We reviewed the literature to find original studies assessing the use of prostaglandin F2α analogs in these settings. Studies and reports were analyzed in regards to androgenic alopecia, alopecia areata, chemotherapy-induced alopecia, vitiligo, and hypopigmented scarring. Based on the results of these studies, and consideration of pathophysiologic mechanism, the most promising applications for prostaglandin F2α analogs include androgenic alopecia, chemotherapy-induced alopecia, and alopecia areata concurrently treated with corticosteroids.

Incidence of deepening of the upper eyelid sulcus in prostaglandin-associated periorbitopathy with a latanoprost ophthalmic solution. Eye (Lond) 2014; 28:1446-51. [PMID: 25233818 DOI: 10.1038/eye.2014.224] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Accepted: 08/08/2014] [Indexed: 11/08/2022] Open
Abstract
PURPOSE Among some local side effects of prostaglandin-associated periorbitopathy (PAP), deepening of the upper eyelid sulcus (DUES) is the most prominent clinical feature, and is one of the most significant adverse cosmetic events. Here, we prospectively investigated the incidence of DUES in Japanese open-angle glaucoma patients initially treated with latanoprost (Xalatan 0.005%) ophthalmic solution. METHODS This was an open-label prospective study. Facial photographs and subjective reports of the recognition of DUES were obtained at the beginning of latanoprost treatment and at 2, 4, and 6 months thereafter. Intraocular pressure (IOP) was measured at three consecutive visits before and after treatment with latanoprost. The incidence of DUES was evaluated objectively by three blinded investigators who compared the series of photographs. RESULTS A total of 52 eyes of 52 newly diagnosed open-angle glaucoma Japanese patients (28 males, 24 females) were evaluated. The objective rate of DUES was 1/52 (2%; 95% CI 0.05 to 10.7%) at 2 months, 2/52 (4%; 95% CI 0.5 to 13.9%) at 4 months, and 3/52 (6%; 95% CI 1.2 to 16.9%) at 6 months. During this period, no patient self-reported an occurrence of DUES. Mean IOPs before and after treatment were 16.5±2.9 and 13.8±3.0 mm Hg, respectively. Latanoprost reduced the IOP significantly (P<0.0001, paired t-test). CONCLUSIONS Latanoprost caused DUES rarely and had a robust IOP-lowering effect in Japanese glaucoma patients.

Abstract
PURPOSE To investigate the incidence of deepening of the upper eyelid sulcus (DUES) with topical use of travoprost in Japanese glaucoma patients. PATIENTS AND METHODS This prospective study enrolled 32 primary open-angle glaucoma Japanese patients who had been treated topically with travoprost unilaterally for 6 months at baseline, and started treatment in both eyes. The patients were observed during outpatient visits at 2, 4, and 6 months. At every visit, the photographs of both eyes and forehead were displayed randomly and the presence of DUES was diagnosed when 3 examiners unanimously rated the case as positive. The patients were also asked if they noticed any subjective symptom of DUES. Sex, refraction, and intraocular pressure (IOP) were evaluated as potential risk factors. RESULTS DUES was identified objectively in 34% (11/32) of the patients after 2 months of treatment, and in 53% (17/32) after 4 and 6 months of treatment. The incidence was significantly higher in older patients (P<0.05), but not related to sex, refraction, pretreatment and posttreatment IOP, and IOP reduction. Finally, 41% (7/17) of patients with objectively diagnosed DUES noticed the presence of DUES by themselves. No patient dropped out of the study because of DUES. CONCLUSIONS DUES is a common side effect of topical travoprost treatment in Japanese glaucoma patients.

Abstract
Lowering intraocular pressure (IOP) is the only proven therapeutic intervention for glaucomatous optic neuropathy. Despite advances in laser and microsurgical techniques, medical IOP reduction remains the first-line treatment option for the majority of patients with open-angle glaucoma. Prostaglandin analogs are the most efficacious topical agents and carry a remarkable safety profile. Topical beta-blockers, alpha-agonists, and carbonic anhydrase inhibitors are often employed as adjunctive agents for further IOP control. Newer preserved and nonpreserved formulations are available and appear to be less toxic to the ocular surface. Oral carbonic anhydrase inhibitors, miotic agents, and hyperosmotics are infrequently used due to a host of potentially serious adverse events. Medical therapies on the horizon include rho-kinase inhibitors, neuroprotective interventions, and gene therapies.

Abstract
PURPOSE Upper eyelid sulcus deepening has recently been reported as an adverse effect of prostaglandin (PG) eye drop use. However, no data are available regarding the frequency of upper eyelid sulcus deepening caused by different types of PG eye drops. We used 5 types of PG eye drops in Japanese subjects and examined the frequency of appearance of upper eyelid sulcus deepening in these subjects. PATIENTS AND METHODS The study included 250 patients (250 eyes) diagnosed with primary open-angle glaucoma or ocular hypertension. Five healthy patients were included as controls. One eye of each patient was treated with one of the following PG eye drops for >3 months: latanoprost, travoprost, tafluprost, bimatoprost, and isopropyl unoprostone. A single-lens reflex camera was used to photograph the open eyelids. Three ophthalmologists independently judged the appearance of the deepened upper eyelid sulcus in the photographs of the 250 patients and 5 controls by comparing the right and left eyes. A subjective self-reported symptom questionnaire was also administered. RESULTS Upper eyelid sulcus deepening was objectively (photograph) and subjectively (questionnaire) noted in 24.0% and 12.0%, 50.0% and 24.0%, 18.0% and 10.0%, 60.0% and 40.0%, and 8.0% and 10.0% of the patients in the latanoprost, travoprost, tafluprost, bimatoprost, and unoprostone groups, respectively. It occurred more frequently (objectively and subjectively) in the bimatoprost group than in the latanoprost, the tafluprost, and the unoprostone groups (P<0.001). CONCLUSION Upper eyelid sulcus deepening frequently occurred with bimatoprost usage, and this effect should be sufficiently elucidated before starting bimatoprost treatment.

Abstract
Background Deepening of the upper eyelid sulcus (DUES) is a common complication of prostaglandin F2α analog treatment, which causes cosmetic problems. However, identifying this condition using photographs is difficult due to such problems as the camera flash effects, blepharoptosis or wide-open eyes. Purpose We investigated the association between a DUES-like appearance and wide-open eyes regarding the presence of wide-open eyes as a cause for overestimating the incidence of DUES. Subjects and Methods One eye and the forehead in 100 subjects (31 younger subjects, 30 older subjects and 39 patients with blepharoptosis) were evaluated in the present study. Digital photographs of the subjects with natural open and wide-open eyes were taken with a flash. Five signs (a puffy eyelid, the presence/absence of the upper eyelid sulcus (UES), wrinkles on the forehead with natural open eyes and an increase in the number of wrinkles on the forehead and a DUES-like appearance with wide-open eyes) were judged to be negative or positive by three independent observers. Univariate and multivariate logistic regression analyses were performed to determine the independent predictor(s) of a DUES-like appearance with wide-open eyes. Results Fourteen subjects (four young, three old and seven subjects with blepharoptosis) were judged to have a DUES-like appearance with wide-open eyes (14%). The only predictive factor was the presence of UES in the patients with natural open eyes (odds ratio = 17.244, 95% confidence interval: 3.447–86.270, P<0.001). Among the 12 UES-positive subjects, six (50%) exhibited a DUES-like appearance with wide-open eyes. Conclusions The presence of wide-open eyes can thus cause a DUES-like appearance. Blepharoptosis itself is not a predictive factor; however, care should be taken not to overestimate the incidence of DUES, especially in patients with UES with natural open eyes, as a DUES-like appearance can be caused by wide-open eyes, even in treatment-naïve patients.

Abstract
In vitro cytotoxicity of tafluprost, which is the most recently developed anti-glaucoma prostaglandin (PG) analog, in ocular surface cells is addressed in comparison with other PG analogs. Irrespective of cell lines and models, the cytotoxicity of anti-glaucoma PG eyedrops was primarily related to the concentration of benzalkonium chloride (BAK) contained in the eyedrops as a preservative. Accordingly, preservative-free tafluprost was apparently less cytotoxic than BAK-preserved PG analogs. Furthermore, our study for cytotoxicity assays on ocular cells, conducted by comprehensive investigations covering a variety of concentrations and treatment times, which is termed the cell viability score (CVS) system, demonstrated that 0.001% BAK-preserved tafluprost was not cytotoxic, and suggested that tafluprost may even reduce the cytotoxic effect of BAK. It has been reported that adverse reactions associated with tafluprost in healthy human volunteers and patients with glaucoma include conjunctival hyperemia, eyelid pigmentation, eyelash bristles, and deepening of upper eyelid sulcus. Nonetheless, most clinical studies have demonstrated that not only preservative-free tafluprost but also BAK-preserved tafluprost is well tolerated and safe in patients with glaucoma and ocular hypertension.

Abstract
Topical Bimatoprost is a common and popular prostaglandin analog used as an ocular hypotensive agent in the treatment of glaucoma. Side effects include ocular hyperaemia, ocular pruritus, and periocular and iris pigmentary changes. Perioribital lipodystrophy is another well-documented outcome associated with chronic use of topical bimatoprost, which results in periorbital hallowing, upper eyelid sulcus deepening, eyelid retraction and enophthalmos. We report an unusual case of periocular muscle atrophy and weakness from unilateral topical bimatoprost use. Our patient had primary angle closure and experienced a right upper eyelid ptosis 2 months after she started to use topical bimatoprost in that eye. Clinical measurements of her eyelids clearly showed reduction in the function of her right levator muscle, suggesting that effects of topical bimatoprost may not be limited to periorbital fat. She was advised to stop topical bimatoprost and right ptosis correction surgery with levator muscle advancement was performed successfully. Ophthalmologists and patients should be aware of this potential rare side effect of topical bimatoprost, as it may be potentially disfiguring, especially with monocular use. However, its exact mechanism of action needs to be clarified further.

Abstract
BACKGROUND In Graves' orbitopathy (GO), increased proliferation, excess adipogenesis, and hyaluronan overproduction produce GO exophthalmos. Enophthalmos occurs in some glaucoma patients treated with Bimatoprost (prostaglandin F2α, PGF2α) eye drops. We hypothesized that enophthalmos is secondary to reductions in orbital tissue proliferation, adipogenesis, and/or increased lipolysis. We aimed to determine which of these is affected by PGF2α by using the 3T3-L1 murine preadipocyte cell line and primary human orbital fibroblasts (OFs) from GO patients (n=5) and non-GO (n=5). METHODS 3T3-L1 cells and orbital OFs were cultured alone or with PGF2α (all experiments used 10(-8) to 10(-6) M) and counted on days 1/2/3 or 5, respectively; cell cycle analysis (flow cytometry) was applied. Adipogenesis (in the presence/absence of PGF2α) was evaluated (day 7 or 15 for 3T3-L1 and primary cells, respectively) morphologically by Oil Red O staining and quantitative polymerase chain reaction measurement of adipogenesis markers (glycerol-3-phosphate dehydrogenase and lipoprotein lipase, respectively). For lipolysis, in vitro-differentiated 3T3-L1 or mature orbital adipocytes were incubated with norepinephrine and PGF2α and free glycerol was assayed. Appropriate statistical tests were applied. RESULTS The population doubling time of 3T3-L1 was 27.3±1.4 hours-significantly increased by dimethyl sulfoxide 0.02% to 44.6±4.8 hours (p=0.007) and further significantly increased (p=0.049 compared with dimethyl sulfoxide) by 10(-8) M PGF2α to 93.6±19.0 hours, indicating reduced proliferation, which was caused by prolongation of G2/M. GO OFs proliferated significantly more rapidly than non-GO (population doubling time 5.36±0.34 or 6.63±0.35 days, respectively, p=0.035), but the proliferation of both was significantly reduced (dose dependent from 10(-8) M) by PGF2α, again with prolongation of G2/M. Adipogenesis in 3T3-L1 cells was minimally affected by PGF2α when assessed morphologically, but the drug significantly reduced transcripts of the glycerol-3-phosphate dehydrogenase differentiation marker. GO OFs displayed significantly higher adipogenic potential than non-GO, but in both populations, adipogenesis, evaluated by all 3 methods, was significantly reduced (dose dependent from 10(-8) M) by PGF2α. There was no effect of PGF2α on basal or norepinephrine-induced lipolysis, in 3T3-L1 or human OFs, either GO or non-GO. CONCLUSIONS The results demonstrate that PGF2α significantly reduces proliferation and adipogenesis and that human OFs are more sensitive to its effects than 3T3-L1. Consequently, PGF2α could be effective in the treatment of GO.
