RESUMEN
Acute angle closure glaucoma is a sight-threatening condition that may lead to blindness. This is a case report of a woman who presented to the emergency department (ED) with acute angle closure glaucoma following use of an over-the-counter (OTC) homeopathic eye drop containing atropa belladonna (deadly nightshade). A 55-year-old woman presented to the ED with a 5-day history of left eye redness, swelling, tearing, and foreign-body sensation that had acutely worsened in the last two days. Her exam revealed mild left conjunctival injection with watery tearing and a hazy appearance of her left cornea. Fluorescein staining was negative, while tonometry revealed elevated intraocular pressure on the left, suggestive of acute angle closure glaucoma. She was urgently referred to ophthalmology. The etiology of the acute angle closure glaucoma was initially unclear however, with additional prompting, she revealed that two days prior she had started using homeopathic OTC eye drops. Inspection of the eyedrop's ingredients revealed that atropa belladonna was the primary ingredient and likely precipitated her isolated episode of acute angle closure glaucoma. A high level of clinical suspicion and focused ophthalmic exam including tonometry is essential to identify acute angle closure glaucoma in the ED. We present a case report of acute angle closure glaucoma associated with the use of homeopathic belladonna-containing eyedrops. Our report reinforces the necessity to perform thorough medication and supplement history given the prevalence of physiologically active substances available in OTC medications.

INTRODUCTION: Theoretically, benzodiazepines (BZDs) can narrow the iridocorneal angle and induce acute angle-closure glaucoma (AACG). However, little evidence exists regarding this association. OBJECTIVE: The objective of this study was to assess whether the use of BZDs is associated with the risk of AACG. METHODS: We conducted a population-based case-crossover study using the nationwide claims database of the National Health Insurance Service in Korea. Patients with newly diagnosed AACG-between 1 January 2013 and 31 December 2016-who had received at least one BZD prescription prior to AACG diagnosis were enrolled. The date of AACG diagnosis was set as the index date. We assessed BZD use by each patient during a 30-day case period prior to the index date and three consecutive control periods that preceded this date. We used conditional logistic regression that adjusted for concomitant medications to determine the odds ratio for the use of BZDs in the case period compared with that in the control period in patients with incident AACG. RESULTS: Of the 11,093 patients with incident AACG, 6709 received a prescription for BZD prior to diagnosis. BZD use was associated with an increased risk of AACG [adjusted odds ratio (aOR) = 1.40; 95% confidence interval (CI) 1.27-1.54]. AACG risk was similar for short-acting (aOR = 1.40, 95% CI 1.24-1.57) and long-acting BZDs (aOR = 1.33, 95% CI 1.18-1.50). CONCLUSION: We found that BZD use was associated with AACG risk in the Korean population. Clinicians should carefully monitor the occurrence of visual disturbance in BZD-treated patients.

BACKGROUND: Garcinia cambogia contains hydroxycitric acid. Hydroxycitric acid is a potent competitive inhibitor of adenosine triphosphate citrate lyase which is a key enzyme in the synthesis of fatty acids. Hydroxycitric acid also regulates the level of serotonin. In these regards, hydroxycitric acid has been reported to exhibit weight loss activity. Adverse reactions of G. cambogia from numerous clinical studies demonstrated relatively mild reactions. However, there are some complications of G. cambogia reported in the past: acute liver injury, acute hepatitis, and hepatic failure. However, ocular complications of G. cambogia have not been reported yet. CASE PRESENTATION: A 35-year-old female visited our clinic with decreased vision in the left eye and ocular pain in both eyes for the last 6 days. She also complained of headache, dizziness, and nausea. She had taken G. cambogia extract more than the recommended dose. There was myopic shift with anterior chamber shallowing in both eyes, especially in the left eye. Moreover, swelling and retinal folds of peripapillary retinal nerve fiber layer and macula were observed in both eyes. These ocular complications of G. cambogia extract resolved after discontinuation of the extract and topical and oral steroid treatment. Herein, we report the first case of ocular complications of G. cambogia extract diet pill assessed with optical coherence tomography of optic disk and macula along with dual Scheimpflug analyzer. CONCLUSION: It is necessary that physicians dealing with obesity advice patients about possible visual disturbance of this extract when taken in overdose so that they can see an ophthalmologist immediately.

RATIONALE: Cases of bilateral acute angle closure have been reported after use of various drugs. PATIENT CONCERNS: A 52-year-old woman visited the emergency room and complained of acute bilateral ocular pain and decreased vision accompanied by headache, nausea, and vomiting. One day before, she had started a herbal medicine containing Ma-huang for weight loss. On examinations, myopic shift, edematous cornea, increased intraocular pressure, shallow anterior chamber, and thickened choroid on both eyes were observed. DIAGNOSES: Angle closure glaucoma induced by drug (Ma-huang). INTERVENTIONS: To promptly quit the offending drug and apply ocular hypotensives and cycloplegics. OUTCOMES: Her symptoms and signs were relieved after antiglaucoma medications and no significant recurrence has been occurred. LESSONS: Physicians prescribing weight loss medications containing Ma-huang must be aware of the potentially sight-threatening adverse effect of bilateral acute angle closure.

PURPOSE: To report the first case of presumed bilateral acute angle closure (AAC) secondary to ingestion of the dietary supplement, methyl-sulfonyl-methane (MSM). PATIENT: A 35-year-old woman presented with bilateral AAC 1 week after starting multiple dietary supplements, one of which contained MSM. Ultrasound biomicroscopy demonstrated bilateral anterior rotation of the iris-lens diaphragm, ciliary body edema, and choroidal effusion. Four days after discontinuation of the supplements, her angle closure and uveal effusion resolved, and her best-corrected vision recovered to 20/20 bilaterally. DISCUSSION: Sulfa-based drugs have been reported to cause AAC, choroidal effusion, and ciliary body edema. In our patient, the coincidence of bilateral AAC with choroidal and ciliary body effusion that began 1 week after starting dietary supplements was suspicious for drug-induced AAC. The dietary supplement Basic Detox Nutrients contains MSM, the only constituent in the patient's medication list with a sulfonyl moiety. Given the similarities in chemical structure and clinical presentation, we postulate that MSM induces AAC in a manner similar to mechanisms previously described for other sulfa-based drugs. CONCLUSIONS: As MSM continues to be used and studied for its anti-inflammatory and antioxidative properties, investigators and marketers will need to be cognizant of its potential to cause AAC and provide proper warning to consumers.

Acute angle-closure glaucoma (AACG) is an ocular emergency that may be precipitated by certain types of medications. Antidepressant drugs can affect a number of neurotransmitters, which are involved in the regulation of the iris, which may precipitate AACG. We used a case-crossover study design to investigate the association between recent exposure to antidepressant drugs and AACG. We identified patients with AACG among adults aged 66 years or older between 1998 and 2010 in Ontario using linked population-based administrative databases. We identified intermittent users of antidepressant medications through prescription drug claims in the year preceding AACG. We determined antidepressant exposure in the period immediately before AACG and compared it with antidepressant exposure in 2 earlier control periods. We used conditional logistic regression to determine the odds ratio for antidepressant exposure in the hazard period compared with the control periods. A total of 6470 patients with AACG occurred during the study period. The mean age of the patients was 74.3 years, and 66% were female. Overall, 5.6% of individuals were intermittent users of antidepressant drugs in the year preceding AACG. The odds ratio for any antidepressant exposure in the period immediately preceding AACG was 1.62 (95% confidence interval, 1.16-2.26). An increased risk of AACG was also observed in several subgroups. We conclude that recent exposure to antidepressant drugs is associated with an increased risk of AACG. Clinicians should remain vigilant for the development of this uncommon but potentially serious adverse event after initiating antidepressant therapy.

We present a case of a 63-year-old woman who presented to an ED with bifrontal headache, nausea and vomiting and reduced visual acuity. Examination revealed bilateral elevated intraocular pressures, corneal haze, shallow anterior chambers and poorly reactive, mid-dilated pupils. Diagnosis was made of simultaneous bilateral acute angle closure glaucoma. A complete drug history revealed that she had been using an over-the-counter cold and flu remedy whose active ingredients included atropa belladonna, an herb with anticholinergic properties. It is likely that drug-induced dilatation of the individual's pupils precipitated this angle closure emergency. In the report we discuss the risk factors for angle closure glaucoma, and review the local and systemic drugs known to trigger this sight-threatening emergency.
