Is Ultra-Processed Food Intake Associated with a Higher Risk of Glaucoma? A Prospective Cohort Study including 19,255 Participants from the SUN Project.

OBJECTIVE: The aim of this study was to examine the relationship of ultra-processed food (UPF) intake with the incidence of glaucoma in a large sample of Spanish university graduates followed prospectively. METHODS: Prospective cohort study using data from the SUN Project. A final sample of 19,225 participants (60.1% women) was included in this study, with a mean age of 38.2 years (standard deviation (SD) = 12.4). Participants were followed-up for a mean time of 12.9 years (SD = 5.4). Dietary intake was measured using a 136-item semiquantitative food-frequency questionnaire. UPFs were defined based on the NOVA classification system. Glaucoma diagnosis was determined by asking the participants if they had ever been diagnosed with glaucoma by an ophthalmologist. This self-reported diagnosis of glaucoma has been previously validated. RESULTS: After adjusting for several covariates, participants with the highest UPF consumption were at higher risk of glaucoma (hazard ratio (HR) = 1.83; 95% confidence interval (CI) 1.06 to 3.17) when compared to participants in the lowest category of UPF consumption. Regarding subgroup analyses, a significant multiplicative interaction was found for age (p = 0.004) and omega 3:6 ratio (p = 0.040). However, an association between UPF consumption and glaucoma was only found in older participants (aged ≥ 55 years), in men, in the most physically active group, in the group of non- or former smokers, in those with a lower omega 3:6 ratio, and in those with a lower energy intake. Regarding the contribution of each type of UPF group, UPF coming from sweets showed a significant risky effect (HR = 1.51; CI 95% 1.07 to 2.12). CONCLUSIONS: This prospective cohort study shows that participants with a greater UPF consumption have a higher risk of developing glaucoma when compared to participants with a lower consumption. Our findings emphasize the relevance of monitoring and limiting the consumption of UPFs as a means of preventing glaucoma incidence.

Glaucoma in a patient with Singleton-Merten syndrome.

A 2-year-old girl presented for evaluation of glaucoma suspect status. Despite her lack of buphthalmia, her clear corneas, and absence of Haab's striae, she was found to have an intraocular pressure of 45 mm Hg in the right eye and 47 mm Hg in the left eye and significant optic nerve cupping. Both eyes were initially treated with goniotomies, trabeculotomies, and later Baerveldt glaucoma implants. She was diagnosed with Singleton-Merten syndrome from a DDX58 pathogenic variant, with congenital glaucoma, juvenile progressive high myopia, hypoplastic nails, and abnormal dentition.

[Acupuncture for glaucoma-induced optic atrophy: a randomized controlled trial].

OBJECTIVE: To observe the clinical effect of acupuncture for glaucoma-induced optic atrophy. METHODS: A total of 70 patients (89 affected eyes) with glaucoma-induced optic atrophy were randomized into an observation group and a control group, 35 cases in each group. The control group was given basic western medicine treatment. In the observation group, on the basis of the treatment in the control group, acupuncture was applied at main acupoints i.e. Baihui (GV 20), Shangjingming (Extra), Chengqi (ST 1), Fengchi (GB 20), Zusanli (ST 36), combined with supplementary acupoints based on syndrome differentiation, once every three days, twice a week. The treatment for 3 months was required in both groups. Before treatment, after treatment and in follow-up of 6 months after treatment, the best corrected visual acuity (BCVA), intraocular pressure (IOP), indexes of visual field (visual field index [VFI], mean deviation [MD], pattern standard deviation [PSD]) and mean thickness of retinal nerve fiber layer (RNFL) were observed in the two groups. RESULTS: Compared before treatment, BCVA was decreased after treatment and in follow-up in the control group (P<0.05); in the follow-up, BCVA in the observation group was higher than that in the control group (P<0.05). On each time point before and after treatment, there was no significant difference within or between the two groups (P>0.05). After treatment and in the follow-up, the mean thickness of RNFL was larger than the control group (P<0.05). CONCLUSION: On the basis of the basic western medicine treatment, acupuncture can delay the decline of vision and the thinning of retinal nerve fiber layer in patients with glaucoma-induced optic atrophy.

Severe Adverse Events of Periocular Acupuncture: A Review of Cases.

Acupuncture is recognized as a component of alternative medicine and is increasingly used worldwide. Many studies have shown the various effects of acupuncture around the eyes for ophthalmologic or nonophthalmologic conditions. For ophthalmologic conditions, the effect of acupuncture on dry eye syndrome, glaucoma, myopia, amblyopia, ophthalmoplegia, allergic rhinoconjunctivitis, blepharospasm, and blepharoptosis has been reported. Recently, several studies on dry eye syndrome have been reported and are in the spotlight. However, given the variety of study designs and reported outcomes of periocular acupuncture, research is still inconclusive, and further studies are required. In addition, although a systematic and reliable safety assessment is required, to the best of our knowledge, there have been no reports of a literature review of ocular complications resulting from periocular acupuncture. This review collected cases of ocular injury as severe adverse events from previously published case reports of periocular acupuncture. A total of 14 case reports (15 eyes of 14 patients) of adverse events published between 1982 and 2020 were identified. This review article provides a summary of the reported cases and suggestions for the prevention and management of better visual function prognosis.

Sphenoid Bone Dysplasia: A Rare Cause of Compressive Optic Neuropathy Mimicking Glaucoma.

Fibrous dysplasia is a benign, rare bone disease in which bone is replaced by fibro-osseous tissue to varying degrees. It can present differently depending on the amount of compression caused by the fibro-osseous tissue. Patients are usually asymptomatic, but symptoms related to cranial nerve compression may occur. In this case report, we describe a 45-year-old woman with sphenoid bone dysplasia which compressed the optic nerve and caused unilateral optic disc cupping that mimicked glaucoma. Our case highlights the importance of including compressive etiologies associated with optic disc cupping in the differential diagnosis of glaucoma.

ACE-Vitamin Index and Risk of Glaucoma: The SUN Project.

BACKGROUND: Previous studies regarding antioxidant consumption and glaucoma have shown contradictory results. The aim of this study was to analyze the combined effect of the consumption of three vitamins (A, C and E) on the incidence of glaucoma in the SUN Project. METHODS: For this study, 18,669 participants were included. The mean follow-up was 11.5 years. An index including vitamins A, C and E (ACE-Vitamin Index) was calculated. Vitamin intake was extracted from participants' dietary data and vitamin supplements, if taken. Information on glaucoma incidence was collected by previously validated self-reported questionnaires. The association between glaucoma and vitamin intake was assessed by repeated-measures Cox regression using multi-adjusted hazard ratios. RESULTS: A total of 251 (1.3%) cases of glaucoma were detected. Participants with a higher ACE-Vitamin Index presented a reduced risk of glaucoma compared to participants with lower consumption (adjusted HR = 0.73; 95% CI, (0.55-0.98)). When each vitamin was analyzed individually, none of them had a significant protective effect. The protective effect of the ACE-Vitamin Index was higher in men and older participants (≥55 year). CONCLUSIONS: The consumption of vitamins A, C and E considered separately do not seem to exert a protective effect against glaucoma, but when these vitamins are considered together, they are associated with a lower risk of glaucoma.

Spontaneously Arrested Bilateral Primary Congenital Glaucoma: A Case Report From Ethiopia.

Background: Primary congenital glaucoma is potentially blinding condition characterized by elevated intraocular pressure and optic disc cupping. It is typically bilateral and usually manifest in the first year of life. Spontaneously arrested primary congenital glaucoma can occur, but it is very rare. Case Report: A 32-year-old male patient from North Shewa presented to the department of ophthalmology, Menelik II Hospital with deterioration of vision. On examination he had large corneas with horizontal diameter of 14 mm, increased axial length, faint corneal stromal opacity and Haab's striae of both eyes. Anterior chamber angles were wide open. His intraocular pressure, optic nerve head appearance and visual field in both eyes were normal. He had subluxated dense cataract of the right eye. Conclusion: Late presentation with sequelae of primary congenital glaucoma without optic neuropathy is possible. Regular follow-up of spontaneously arrested congenital glaucoma and scleral fixation of intraocular lens is recommended.

Vitamin intake and glaucoma risk: A systematic review and meta-analysis.

There is currently a lack of high-quality research on the best dietary recommendations for patients with early glaucoma or at high risk for glaucoma. This meta-analysis aims to clarify the relationship between vitamin intake and glaucoma risk. Electronic databases, including PubMed, EMbase, ScienceDirect, Cochrane Database, Clinicaltrials.gov, and Google Scholar, were searched for publications indexed as of September 18, 2021. Data were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). The I2 index was used to assess heterogeneity. We performed five meta-analyses of existing studies to summarize the evidence on the association between vitamin intake and glaucoma risk. The initial search identified 689 studies, eight of which (262,189 patients) met the eligibility criteria for the meta-analysis. The data showed that high-dose intake of vitamins A (OR=0.63, 95%CI [0.53, 0.76]) and B (OR=0.71, 95%CI [0.64, 0.80]) but not vitamins C (OR=0.69, 95%CI [0.48, 1.01]), D (OR=0.90, 95%CI [0.45, 1.83]), or E (OR=0.91, 95%CI [0.71, 1.16]) was associated with a low prevalence of glaucoma. The results of this study demonstrated that high-dose intake of vitamins A and B, but not vitamins C, D, or E, was associated with a low prevalence of glaucoma.

The high-pressure bleb.

A 45-year-old male presented with a slowly progressive, painless swelling in his right eye for the past 6 months. He had undergone an open globe injury repair 10 years back and an eventful cataract surgery 5 years back. The presenting visual acuity in the affected eye was perception of light with inaccurate projection of rays. The intraocular pressure was 44 mm Hg with advanced glaucomatous cupping. The swelling was identified to be a communicating sub-tenon cyst secondary to scleral wound dehiscence from secondary angle closure glaucoma. Wound re-suturing, cyst excision and diode laser cyclophotocoagulation was performed in a single sitting, with explained poor visual prognosis.

Yoga-induced uveitis glaucoma hyphema syndrome.

A 74-year-old pseudophakic white woman with pseudoexfoliation syndrome presented with right eye pain and photophobia and was found to have pseudophacodenesis with recurrent episodes of anterior uveitis, microhyphema, and elevated intraocular pressure (IOP). All episodes occurred after yoga sessions with intensive facedown postures. Ultrasound biomicroscopy (UBM) performed in supine and prone positions demonstrated significant change in the lens-bag complex position, with lens-iris touch. The patient underwent intraocular lens (IOL) explantation, anterior vitrectomy, and flanged intrascleral haptic-fixated IOL placement via double-needle technique, with resolution of all symptoms.

Surgical outcomes of Glaucoma associated with Axenfeld-Rieger syndrome.

BACKGROUND: The surgical management of glaucoma associated with Axenfeld-Rieger Syndrome (ARS) is poorly described in the literature. The goal of this study is to compare the effectiveness of various glaucoma surgeries on intraocular pressure (IOP) management in ARS. METHODS: Retrospective cohort study at a university hospital-based practice of patients diagnosed with ARS between 1973 and 2018. Exclusion criterion was follow-up less than 1 year. The number of eyes with glaucoma (IOP ≥ 21 mmHg with corneal edema, Haabs striae, optic nerve cupping or buphthalmos) requiring surgery was determined. The success and survival rates of goniotomy, trabeculotomy±trabeculectomy (no antifibrotics), cycloablation, trabeculectomy with anti-fibrotics, and glaucoma drainage device placement were assessed. Success was defined as IOP of 5-20 mmHg and no additional IOP-lowering surgery or visually devastating complications. Kaplan-Meier survival curves and the Wilcoxon test were used for statistical analysis. RESULTS: In 32 patients identified with ARS (median age at presentation 6.9 years, 0-58.7 years; median follow-up 5.4 years, 1.1-43.7 years), 23 (71.9%) patients were diagnosed with glaucoma at median age 6.3 years (0-57.9 years). In glaucomatous eyes (46 eyes), mean IOP at presentation was 21.8 ± 9.3 mmHg (median 20 mmHg, 4-45 mmHg) on 1.0 ± 1.6 glaucoma medications. Thirty-one eyes of 18 patients required glaucoma surgery with 2.2 ± 1.2 IOP-lowering surgeries per eye. Goniotomy (6 eyes) showed 43% success with 4.3 ± 3.9 years of IOP control. Trabeculotomy±trabeculectomy (6 eyes) had 17% success rate with 14.8 ± 12.7 years of IOP control. Trabeculectomy with anti-fibrotics (14 eyes) showed 57% success with 16.5 ± 13.5 years of IOP control. Ahmed© (FP7 or FP8) valve placement (8 eyes) had 25% success rate with 1.7 ± 1.9 years of IOP control. Baerveldt© (250 or 350) device placement (8 eyes) showed 70% success with 1.9 ± 2.3 years of IOP control. Cycloablation (4 eyes) had 33% success rate with 2.7 ± 3.5 years of IOP control. At final follow-up, mean IOP (12.6 ± 3.8 mmHg, median 11.8 mmHg, 7-19 mmHg) in glaucomatous eyes was significantly decreased (p < 0.0001), but there was no difference in number of glaucoma medications (1.6 ± 1.5, p = 0.1). CONCLUSIONS: In our series, greater than 70% of patients with ARS have secondary glaucoma that often requires multiple surgeries. Trabeculectomy with anti-fibrotics and Baerveldt glaucoma drainage devices showed the greatest success in obtaining IOP control.

A Dietary Combination of Forskolin with Homotaurine, Spearmint and B Vitamins Protects Injured Retinal Ganglion Cells in a Rodent Model of Hypertensive Glaucoma.

There is indication that nutritional supplements protect retinal cells from degeneration. In a previous study, we demonstrated that dietary supplementation with an association of forskolin, homotaurine, spearmint extract and B vitamins efficiently counteracts retinal dysfunction associated with retinal ganglion cell (RGC) death caused by optic nerve crush. We extended our investigation on the efficacy of dietary supplementation with the use of a mouse model in which RGC degeneration depends as closely as possible on intraocular pressure (IOP) elevation. In this model, injecting the anterior chamber of the eye with methylcellulose (MCE) causes IOP elevation leading to RGC dysfunction. The MCE model was characterized in terms of IOP elevation, retinal dysfunction as determined by electrophysiological recordings, RGC loss as determined by brain-specific homeobox/POU domain protein 3A immunoreactivity and dysregulated levels of inflammatory and apoptotic markers. Except for IOP elevation, dysfunctional retinal parameters were all recovered by dietary supplementation indicating the involvement of non-IOP-related neuroprotective mechanisms of action. Our hypothesis is that the diet supplement may be used to counteract the inflammatory processes triggered by glial cell activation, thus leading to spared RGC loss and the preservation of visual dysfunction. In this respect, the present compound may be viewed as a potential remedy to be added to the currently approved drug therapies for improving RGC protection.

Neuroprotective and Anti-Inflammatory Effects of a Hydrophilic Saffron Extract in a Model of Glaucoma.

Glaucoma is a neurodegenerative disease characterized by the loss of retinal ganglion cells (RGCs). An increase in the intraocular pressure is the principal risk factor for such loss, but controlling this pressure does not always prevent glaucomatous damage. Activation of immune cells resident in the retina (microglia) may contribute to RGC death. Thus, a substance with anti-inflammatory activity may protect against RGC degeneration. This study investigated the neuroprotective and anti-inflammatory effects of a hydrophilic saffron extract standardized to 3% crocin content in a mouse model of unilateral, laser-induced ocular hypertension (OHT). Treatment with saffron extract decreased microglion numbers and morphological signs of their activation, including soma size and process retraction, both in OHT and in contralateral eyes. Saffron extract treatment also partially reversed OHT-induced down-regulation of P2RY12. In addition, the extract prevented retinal ganglion cell death in OHT eyes. Oral administration of saffron extract was able to decrease the neuroinflammation associated with increased intraocular pressure, preventing retinal ganglion cell death. Our findings indicate that saffron extract may exert a protective effect in glaucomatous pathology.

Effect of four local anesthetics (tetracaine, proparacaine, lidocaine, and bupivacaine) on intraocular pressure in dogs.

PURPOSE: To measure IOP in animals, it is often necessary to use topical anesthetics. The use of these drugs may cause changes in IOP and interfere with the final results. To address this issue, the effects of four local anesthetics (tetracaine, proparacaine, lidocaine, and bupivacaine) on IOP were investigated in ten adult dogs. METHODS: One drop of tetracaine was instilled in the right eye of half of the dogs and in the left eye of the other dogs; normal saline was instilled in the fellow eyes. The IOP in each dog was measured before and at 0, 5, 10, 15, 20, 25, 30, and 35 min after drug instillation using an electronic rebound tonometer. The effects of the other anesthetics were studied in the same way at intervals of at least 1 week. RESULTS: After instillation of tetracaine, the IOP decreased gradually, such that after 15 min, the IOP was significantly lower than the baseline (p = 0.022) and control values (p = 0.048). Proparacaine also reduced IOP after 10 min compared to baseline values (p = 0.046), but the two other drugs, bupivacaine and lidocaine, had no significant effect on IOP. The duration of eye anesthesia was 16, 20, 22, and 34 min for tetracaine, lidocaine, bupivacaine, and proparacaine, respectively. CONCLUSION: We recommend using drugs that combine inducing longer anesthesia with producing the smallest change in IOP, such as bupivacaine and, subsequently, lidocaine. Tetracaine and proparacaine have a significant effect on IOP, and if these drugs are used, this effect should be considered.

Radius-Maumenee syndrome: a rare cause of glaucoma.

Case presentation of a 41-year-old woman with long-standing bilateral eye injection whose clinical findings included bilateral episcleral vessel engorgement and tortuosity, raised intraocular pressure with open iridocorneal angles and left optic disc cupping. All remaining objective examination was normal. She underwent cranial and orbits CT and CT-angiography scans which were unremarkable. Optical coherence tomography of the peripapillary nerve fibre layer and automated perimetry were compatible with advanced glaucomatous damage on the left eye. The patient was diagnosed with idiopathic elevated episcleral venous pressure or Radius-Maumenee syndrome. If medical therapy is unable to prevent disease progression, left eye filtering surgery will be proposed.

Lifestyles guide and glaucoma (II). Diet, supplements, drugs, sleep, pregnancy, and systemic hypertension. / Guía de estilos de vida y glaucoma (II). Dieta, suplementos, drogas, sueño, embarazo e hipertensión arterial.

PURPOSE: To establish evidence based guidelines to advise patients on the relationship between habits, diet, certain circumstances, diseases and glaucoma. METHODS: Review of all published articles on glaucoma and sports or other activities. The papers were classified according to the level of scientific evidence based on the Oxford Centre for Evidence-based Medicine classification. RESULTS: The evidence on the relationship between diet or supplements and the incidence or progression of glaucoma is insufficient to make a general recommendation for glaucoma patients. Although some studies on normal tension glaucoma suggest that Gingko biloba could reduce glaucoma progression, the results do not allow a general recommendation for all these patients. Similarly, the evidence on the usefulness of vitamin supplements is not conclusive. The studies on smoking do not clearly demonstrate the relationship between this habit and incidence of glaucoma. Marihuana is not a useful treatment for glaucoma. Although the results on the relationship between sleep apnoea and glaucoma are heterogeneous, it is recommended that patients with moderate to intense apnoea are tested for glaucoma. Pregnancy does not influence the course of the disease, but several hypotensive drugs may be harmful for the foetus. Nocturnal systemic hypotension is a risk factor for glaucoma progression. CONCLUSIONS: Certain habits, circumstances, or diseases may have an influence on the onset or progression of glaucoma. It is important to have adequate information about the scientific evidence in the publications in order to properly advise patients.

A Novel Uveolymphatic Drainage Pathway-Possible New Target for Glaucoma Treatment.

Glaucoma is a heterogeneous group of ophthalmic diseases leading to irreversible damage to the optic nerve. While the overall mechanism responsible for glaucoma remains obscure, the most important risk factor is elevated intraocular pressure. The current therapies, whether pharmacological or surgical, are primarily symptomatic with the aim to lower the intraocular pressure (IOP). Poorer response to treatment is associated, for example, with pseudoexfoliation glaucoma, which is determined by blocking the trabecular meshwork (TM) both by pigment grains and the pseudoexfoliation material. It was thought that aqueous humor is drained from the eye by two main pathways: conventional outflow through the TM and Schlemm's canal; and unconventional outflow through the ciliary body through uveal tissue. In 2009 Yucel et al. described and proved the presence of a third pathway for aqueous humor drainage using two specific lymphatic markers: podoplanin, and lymphatic vessel endothelial hyaluronan receptor-1 to identify lymphatic channels in the human ciliary body. The discovery identifies a novel target for IOP-lowering therapies. The most promising group are prostaglandins, which are widely prescribed for glaucoma patients. An intriguing new possibility in glaucoma therapy is using ANGPT agonist. It is still not known if the lymphatic drainage in glaucoma is decreased or dysfunctional and whether lymphatic stimulation can help in removing the improperly accumulated substances, as is seen in pseudoexfoliation glaucoma. However, this new target for glaucoma treatment appears very promising.

Movement of retinal vessels toward the optic nerve head after increasing intraocular pressure in monkey eyes with experimental glaucoma.

A shift or displacement of the retinal blood vessels (RBVs) with neuroretinal rim thinning indicates the progression of glaucomatous optic neuropathy. In chronic open angle glaucoma, individuals with RBV positional shifts exhibit more rapid visual field loss than those without RBV shifts. The retinal vessels reportedly move onto the optic nerve head (ONH) in response to glaucoma damage, suggesting that RBVs are pulled toward the ONH in response to increased cupping. Whether this phenomenon only applies to RVBs located in the vicinity or inside the ONH or, more generally, to RBVs also located far from the ONH, however, is unclear. The aim of this study was to evaluate the movement of RBVs located relatively far from the ONH edge after increasing intraocular pressure (IOP) in an experimental monkey model of glaucoma. Fundus photographs were obtained in 17 monkeys. High IOP was induced in the monkeys by laser photocoagulation burns applied uniformly with 360° irradiation around the trabecular meshwork of the left eye. The right eye was left intact and used as a non-treated control. Considering the circadian rhythm of IOP, it was measured in both eyes of each animal at around the same time-points. Then, fundus photographs were obtained. Using Image J image analysis software, an examiner (N.E.) measured the fundus photographs at two time-points, i.e. before laser treatment (time 1) and the last fundus photography after IOP elevation (time 2). The following parameters were measured (in pixels): 1) vertical diameter of the ONH (DD), 2) distance from the ONH edge to the first bifurcation point of the superior branch of the central retinal vein (UV), 3) distance from the ONH edge to the first bifurcation point of the inferior branch of the central retinal vein (LV), 4) ONH area, and 5) surface area of the cup of the ONH. We calculated the ratios of UV to DD (UV/DD), LV to DD (LV/DD), and the cup area to disc area ratio (C/D). The mean UV/DD at time 1 (0.656 ± 0.233) was decreased at time 2 (0.542 ± 0.192) (p < 0.01), and the mean LV/DD at time 1 (0.642 ± 0.151) was decreased at time 2 (0.534 ± 0.171) (p < 0.01). The mean C/D at time 1 (0.303 ± 0.035) was increased at time 2 (0.556 ± 0.110) (p < 0.01). The mean IOP at time 1 was 19.8 ± 2.5 and that at time 2 was 54.2 ± 15.8. The amount and rate of the change in LV/DD and C/D between time 1 and time 2 were significantly correlated (r = -0.654 and -0.536, p = 0.004 and 0.026, respectively). Therefore, in an experimental monkey model of glaucoma, RBVs located relatively far from the ONH were pulled toward the ONH as cupping increased.

Food components and ocular pathophysiology: a critical appraisal of the role of oxidative mechanisms.

BACKGROUND AND OBJECTIVES: Three of the major ocular diseases, namely cataracts, age-related macular degeneration and glaucoma are associated with oxidative damage. Disease risk and progression may be reduced through consumption of dietary components. To critically examine the literature on dietary and supplemental intakes of fruit and vegetables, meat, antioxidants (vitamins C, E and A), calcium, folate, iron, and their association with ocular disease. METHODS AND STUDY DESIGN: Google Scholar and key references from texts and publications were searched using search terms (eye disease, antioxidants), (vision, nutrition), no date restriction, only articles in English were included. RESULTS: We found probable evidence that dietary intake of fruits and vegetables, and vitamin C lowered incidence of cataracts and age-related macular degeneration. In high supplemental doses, vitamin C increases macular degeneration risk. Vitamin A from food was protective for cataracts and glaucoma, but not in supplemental form. Vitamin A was associated with lower incidence of macular degeneration. We also found probable evidence that higher intakes of meat increased the risk of cataracts and macular degeneration. Dietary calcium and iron appeared protective against glaucoma, but not in supplemental form. CONCLUSIONS: While a nutrient rich diet high in fruit and vegetables, and associated antioxidants appeared to be protective, we would caution intake of supplementary antioxidants for those with ocular disease.
