Phacoemulsification and Core Vitrectomy in Fuchs' Heterochromic Uveitis.

OBJECTIVE: To evaluate the efficacy of phacoemulsification combined with posterior capsulorhexis, core vitrectomy and ciliary sulcus intraocular lens (IOL) implantation in patients with Fuchs' heterochromic uveitis (FHU). MATERIALS AND METHODS: A total of 18 eyes of 18 patients with FHU underwent cataract surgery were included in the study. 18 eyes with FHU underwent posterior capsulorhexis, core vitrectomy and poly (methyl methacrylate) (PMMA) IOL implantation in the ciliary sulcus. Subjects were chosen for this procedure based on an intraoperative vitreous haziness assessment, performed by indirect ophthalmoscopy. Patients with +2 or more vitreous haziness qualified for this procedure. RESULTS: Of the 83 eyes with FHU that underwent cataract surgery, 18 eyes (21.6%) of 18 patients were employed in the study. There were 11 (61.1%) men and 7 (38.9%) women in the study; ages ranged from 23 to 47, with a mean of 32.06 years. Follow-up ranged from 8 months to 49 months. There were no intraoperative complications except for peripheral iris bleeding in 7 eyes. There was no severe intraocular inflammation in any patient postoperatively. All patients had 0.05 or better logMAR visual acuity after corneal suture removal. Glaucoma developed in 2 patients. For the short term period, the main vision threatening problem was suture-induced astigmatism. CONCLUSION: Cataract surgery combined with posterior capsulorhexis, core vitrectomy and IOL implantation in the ciliary sulcus is safe and leads to good visual outcome due to the removal of the hazy vitreous in patients with FHU.

Measurement of Choroidal Thickness Following Caffeine Intake in Healthy Subjects.

PURPOSE: The aim of this study is to investigate the effect of 200 mg caffeine on subfoveal choroidal thickness (CT) in the macular area as measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in healthy subjects. MATERIALS AND METHODS: Fifty healthy individuals (study group) and 50 healthy individuals (control group) were enrolled in study. In the study group, participants received a 200 mg caffeine capsule and the control group consisted of subjects who received plasebo capsule. The subfoveal CT was measured by EDI-OCT before the caffeine intake and at 30 min, 1 h, 2 h, 3 h, 4 h and 6 h following caffeine intake. RESULTS: SFCT after caffeine intake was significantly decreased at 30 min, 1 h, 2 h, 3 h and 4 h compared to the baseline measurement, while the difference between baseline and 6 h was not statistically significant in the study group. There were no significant differences between the baseline and the other measurement times in the control group (p > 0.05). CONCLUSION: The thinning of CT begins about 30 min after the oral ingestion of 200 mg of caffeine and lasts for about four hours.

Isolated rectus muscle rupture following trauma.

BACKGROUND: Isolated rectus muscle ruptures are rare ophthalmic emergencies which may result in permanent diplopia. OBJECTIVE: To highlight updates on clinical features, surgical treatment options and potential complications for isolated inferior rectus ruptures. CASE: A 39-year-old man came to our emergency department complaining of diplopia and upward deviation of the right eye after experiencing an animal injury. Extraocular movements were limited in the right eye in the downgaze position. The alternate prism and cover test, both at distance and near testing, showed hypertropia of 40 prism diopters (PD) of the right eye. The right eye had periorbital swelling and conjunctival haematoma. An inferior rectus rupture repair was performed under local anesthesia and monitored sedation. Follow-up examination revealed a 20 PD hypertropia, causing diplopia in all gazes. A second surgical intervention was planned six months after the initial surgery, an inferior rectus 6 mm resection was performed, after which orthophoria was achieved in the primary position both at distance and near testing.

Bidirectional Synergistic Vergence.

A 14-year-old boy presented with left ptosis and squint since his childhood. In primary position he had left hypotropia with ptosis (levator function 2 mm). With elevation of the right eye, the left eye depresses and adducts; with depression of the right eye, the left eye elevates and abducts. Forced duction test revealed no restrictive pattern. The synergistic divergence described in the literature was unidirectional and wholly compatible with inferior rectus co-contraction. But this case is bidirectional, and the aberrant upward movement cannot be explained by rectus muscle co-contraction. The two vertical rectus muscles show reciprocal misinnervation, or this effect could be coming from co-contraction of one of the oblique muscles for the movement in one direction.

Non-Recurrence Complications of Fibrin Glue Use in Pterygium Surgery: Prevention and Management.

PURPOSE: To present complications of using fibrin glue in conjunctival-limbal autografting in pterygium surgeries other than recurrences and discuss their prevention and management strategies. MATERIALS AND METHODOLOGY: The charts of all patients who underwent fibrin glue assisted pterygium excision surgery with conjunctival-limbal autograft transplantation from 2010 to 2013 were reviewed. Patients who developed complications except recurrence postoperatively were included in this study. RESULTS: Sixteen (17.39%) of the 92 patients were detected with a complication. Graft dehiscence was diagnosed in 7 (7.6%) patients with 5 of them treated conservatively and 2 patients requiring suturing. Five (5.43%) patients were diagnosed with cyst formation between the graft and conjunctiva or in the graft-removal area; these cysts were primarily excised and no additional problems occurred. Corneal dellen developed in 3 (3.26%) patients and 2 of them regressed after cessation of topical steroids and application of lubricant therapy while one was treated with amniotic membrane transplantation. Residual fibrin glue particles had stiffened on the ocular surface, which resulted in intensive pain and irritation in one (1.08%) patient on the same day of the surgery. The patient's complaints were reduced by removing these particles from the ocular surface under topical anesthesia. CONCLUSION: Complications in fibrin glue assisted pterygium surgery are relatively different from other techniques. To avoid potential complications of fibrin glue in pterygium surgery, peroperatively ophthalmologists should ensure the conjunctival autograft and conjunctiva are properly adhered, fibrin glue remnants are completely removed from the ocular surface, and no Tenon's capsule remains between the graft and the conjunctiva.

Effect of selective laser trabeculoplasty on macular thickness.

BACKGROUND: To investigate the effects of selective laser trabeculoplasty (SLT) on macular thickness change. METHODS: Forty eyes of 40 consecutive patients with uncontrolled primary open-angle glaucoma with medical treatment were included in this prospective study. SLT was performed to the inferior 180°, and macular thickness was measured. Data were collected before SLT, and 1 week and 1 month after SLT. Macular thickness evaluation was performed in five quadrants, the central 1 mm quadrant (fovea = F), the nasal 3 mm quadrant surrounding F (NQ), temporal quadrant, superior quadrant (SQ), and inferior quadrant (IQ). The preoperative and postoperative thicknesses were compared. RESULTS: There was an increase in macular thickness in the NQ, IQ, and SQ on the first week after SLT compared to preoperative measurements. On the other hand, there was no significant increase in the F and temporal quadrant. On the first month after SLT, thickness in the NQ, IQ, and SQ was back to preoperative measurements, and there was no significant change between the preoperative measurements in any quadrant. CONCLUSION: There was no significant increase in macular thickness shortly after SLT in our study.

Comprasion of ICare rebound tonometer and Goldmann applanation tonometer in high myopia.

PURPOSE: To compare intraocular pressure (IOP) measurements with the Goldmann applanation tonometer (GAT) and the ICare rebound tonometer (RBT) in high myopic eyes. PATIENTS AND METHODS: This randomized prospective study included 40 eyes of 40 patients with high myopia. All patients' central corneal thickness (CCT), anterior chamber depth (ACD), axial length (AXL), keratometry, and refractive measurements were recorded and followed by IOP measurement with RBT and GAT. RESULTS: The average CCT, AXL, and ACD were determined to be 514.65 ± 32 µm, 27.65 ± 2.22 mm, and 3.25 ± 0.51 mm, respectively. Mean K was 43.27 ± 1.4 D and mean spherical equivalent was -11.31 ± 4.30 D. The mean IOP values obtained by RBT and GAT were 17.18 ± 3.72 mmHg and 16.48 ± 3.19 mmHg, respectively. The deviations of RBT readings from corrected GAT values were highly correlated with CCT values (r = 0.588, P = 0.0001). The mean corrected GAT reading was 17.49 ± 3.01 mmHg. Linear regression analysis showed that a CCT change of 10 µm resulted in an RBT reading deviation of 0.57 mmHg. The Bland-Altman scatter-plot and McNemar test showed a clinically good level of agreement between the two tonometers. CONCLUSION: This study found a good agreement level between the two tonometers in high myopic patients and that RBT measurements are influenced by CCT variations.

''The association of normal tension glaucoma with Buerger's disease: a case report''.

BACKGROUND: To report a case of a 48-year-old man with Buerger's disease who presented with bilateral normal-tension glaucoma (NTG). CASE PRESENTATION: A 48-year-old man who had been diagnosed with Buerger's disease 12 years ago, and received bilateral below-the-knee amputations for ischemic ulcers of the lower limbs, presented at our clinic due to a sudden loss of visual acuity in the left eye. A fundus exam revealed a cup-to-disc ratio of 0.5 for the right eye and 0.8 for the left eye, arteriolar constriction in both eyes, retinal edema in the inferopapillary area, and splinter hemorrhages and soft exudate in the left eye. We diagnosed the patient as having acute nasal branch retinal artery occlusion in the left eye and bilateral NTG, as a result of the ophthalmologic examination and the other findings. CONCLUSION: Although the pathomechanism of NTG is still unknown, previous studies have suggested that patients with NTG show a higher prevalence of vasospastic disorders. We present the second report of NTG associated with Buerger's disease to be described in the literature.

Elevated Intraocular Pressure due to Arteriovenous Fistula between External Carotid Artery and Facial Vein.

Aqueous outflow via the conventional outflow pathway is dependent on the pressure gradient between intraocular pressure (IOP) and episcleral venous pressure (EVP). Elevated IOP resulting from increased EVP is a well-known complication of arteriovenous fistulas, which are usually between the carotid artery and the cavernous sinus. Arteriovenous malformations usually occur spontaneously, after a trauma or from iatrogenic causes, and they manifest with findings of chemosis, dilatation of the conjunctival vessels, exophthalmos, and extraocular motility limitation. In this study, we present a case of elevated IOP due to facial arteriovenous malformations following a functional neck dissection surgery that caused intraocular pressure elevation.

Evaluation of cardiovascular biomarkers in patients with age-related wet macular degeneration.

AIM: To evaluate levels of homocysteine, asymmetric dimethylarginine (ADMA), and nitric oxide (NO), as well as activity of endothelial NO synthase (eNOS), in patients with age-related macular degeneration (AMD). METHODS: The levels of homocysteine, ADMA, and NO and activity of eNOS in patients who were diagnosed with wet AMD by fundus fluorescein angiography (n=30) were compared to a control group with no retinal pathology (n=30). RESULTS: Levels of homocysteine and ADMA were found to be significantly higher in the wet AMD group than in the control group (P<0.001), whereas NO levels and eNOS activity were higher in the control group (P<0.001). In the wet AMD group, we detected a 2.64- and 0.33-fold increase in the levels of ADMA and homocysteine, respectively, and a 0.49- and 2.41-fold decrease in the eNOS activity and NO level, respectively. CONCLUSION: Elevated levels of homocysteine and ADMA were observed in patients with wet AMD. Increased ADMA may be responsible for the diminished eNOS activity found in these patients, which in turn contributes to the decrease in NO levels, which likely plays a role in the pathogenesis of AMD.

Nd: YAG laser posterior capsulotomy rates in myopic eyes after implantation of capsular tension ring.

BACKGROUND: The aim f this study was to evaluate the effect of capsular tension ring implantation during cataract surgery on the incidence of neodymium: YAG (Nd: YAG) laser posterior capsulotomy in myopic (axial length [AL] ≥25.00 mm) eyes. MATERIAL/METHODS In this retrospective study, the records of the cases of 117 myopic patients who underwent cataract surgery between January 2004 and January 2011 were reviewed. A total of 153 eyes with an axial length of 25 mm or higher were included in the study with consideration of exclusion criteria mentioned below. Eyes were grouped by presence or lack of capsular tension ring (CTR+ and CTR-, respectively). RESULTS: The study included 153 eyes from 107 myopic patients. Hydrophilic acrylic IOL and capsular tension ring (CTR) were implanted in 78 eyes (CTR+ group), and 75 eyes received only the hydrophilic acrylic IOL (CTR- group). Six eyes (7.6%) in CTR+ and 16 eyes (21.3%) in CTR- required Nd: YAG laser capsulotomy within 7 years. The difference between the 2 groups was statistically significant (p=0.021). CONCLUSIONS: Because CTRs significantly decrease subsequent need for Nd: YAG laser posterior capsulotomy in myopic patients, are very inexpensive, and provide other benefits, our data suggest that the use of CTRs in myopic eyes undergoing cataract surgery with an hydrophilic acrylic IOL implantation is advantageous and should be standard practice.

Reduction of conjunctival fibrosis after trabeculectomy using topical α-lipoic acid in rabbit eyes.

PURPOSE: To evaluate the efficacy of α-lipoic acid (ALA) in reducing scarring after trabeculectomy. MATERIALS AND METHODS: Eighteen adult New Zealand white rabbits underwent trabeculectomy. During trabeculectomy, thin sponges were placed between the sclera and Tenon's capsule for 3 minutes, saline solution, mitomycin-C (MMC) and ALA was applied to the control group (CG) (n=6 eyes), MMC group (MMCG) (n=6 eyes), and ALA group (ALAG) (n=6 eyes), respectively. After surgery, topical saline and ALA was applied for 28 days to the control and ALAGs, respectively. Filtrating bleb patency was evaluated by using 0.1% trepan blue. Hematoxylin and eosin and Masson trichrome staining for toxicity, total cellularity, and collagen organization; α-smooth muscle actin immunohistochemistry staining performed for myofibroblast phenotype identification. RESULTS: Clinical evaluation showed that all 6 blebs (100%) of the CG had failed, whereas there were only 2 failures (33%) in the ALAG and no failures in the MMCG on day 28. Histologic evaluation showed significantly lower inflammatory cell infiltration in the ALAGs and CGs than the MMCG. Toxicity change was more significant in the MMCG than the control and ALAGs. Collagen was better organized in the ALAG than control and MMCGs. In immunohistochemistry evaluation, ALA significantly reduced the population of cells expressing α-smooth muscle action. CONCLUSIONS: ΑLA prevents and/or reduces fibrosis by inhibition of inflammation pathways, revascularization, and accumulation of extracellular matrix. It can be used as an agent for delaying tissue regeneration and for providing a more functional-permanent fistula.

Toxic effects of chronic mercury exposure on the retinal nerve fiber layer and macular and choroidal thickness in industrial mercury battery workers.

BACKGROUND: The aim of this study was to evaluate the toxic effects of mercury on retinal nerve fiber layer thickness (RNFLT), macular thickness (MT), and choroidal thickness (CT) by using spectral-domain optical coherence tomography (SD-OCT) in battery industry workers who had been chronically exposed to mercury. MATERIAL/METHODS: Battery factory workers (n=31) and healthy non-factory employee controls (n=15) participated in the study. Participants were divided into 3 groups: Group 1 (n=15) was factory workers who had worked for more than 5 years in a mercury battery factory; Group 2 (n=16) was factory worker who had worked for less than 5 years in a mercury battery factory; and Group 3 (n=15) was healthy non-employees. Systemic symptoms were recorded. Ophthalmic examination included best-corrected visual acuity test, color vision test, full ophthalmologic examination, and SD-OCT of the RNLF, macula, and choroid. To determine mercury exposure, venous blood samples were collected and mercury levels were assessed. RESULTS: In our study group the most common systemic symptoms were insomnia (67.7%) and fatigue (67.7%). There were no significant differences between Group 1 and Group 2, but there were significant differences between Group 3 and both Group 1 and Group 2 in best-corrected visual acuity values (1=2<3), color vision scores, blood mercury levels, and duration (mean ±SD, range) of mercury exposure(1>2>3). OCT values of RNFLTs, MTs, and CTs of all 3 groups were statistically different from each another (1<2<3). CONCLUSIONS: SD-OCT can be useful for evaluating the toxic effects of chronic exposure to mercury.

Topical anesthesia for cataract surgery: the patients' perspective.

Purpose. To evaluate the analgesic efficacy of 0.5% propacaine hydrochloride as topical anesthesia during phacoemulsification surgery. Methods. Intraoperative pain intensity was assessed using a 5-category verbal rating scale during each of three surgical stages. Pain scores from each surgical stage and total pain scores were compared for the factors of patient age, gender, cataract laterality, and type. Results. In comparison of cataract type subgroups, the mean total pain scores and mean stage 2 pain scores in both white mature cataract (WMC) and corticonuclear plus posterior subcapsular cataract (CN + PSC) groups were significantly higher than in the PSC-only (PSC) group (P < 0.05). Conclusion. Phacoemulsification with topical anesthesia is not a completely painless procedure. Pain intensity varies with cataract type and stage of surgery.

Retinal nerve fibre layer, ganglion cell layer and choroid thinning in migraine with aura.

BACKGROUND: The aim of this study was to investigate the thickness of the retinal nerve fiber layer (RNFL), the ganglion cell layer (GCL), and choroid thickness (CT) in patients who have migraines, with and without aura, using spectral optical coherence tomography (OCT). METHODS: Forty-five patients who had migraines without aura (Group 1), 45 patients who had migraines with aura (Group 2), and 30 healthy participants (control group) were included in the study. Spectral OCT was used to measure the RNFL, GCL and CT values for all patients. RESULTS: The mean age of Group 1, Group 2, and the control group was 34.6 ± 4.3, 32.8 ± 4.9, and 31.8 ± 4.6 years, respectively. The mean attack frequency was 3.6/month in Group 1 and 3.7/month in Group 2. The mean age among the groups (p = 0.27) and number of attacks in migraine patients (p = 0.73) were not significantly different. There was significant thinning in the RNFL and GCL in Group 2 (p < 0.05, p < 0.001 respectively), while there were no significant differences in RNFL and GCL measurements between Group 1 and the control group (p > 0.05). All groups were significantly different from one another with respect to CT, with the most thinning observed in Group 2 (p < 0.001). When all migraine patients (without grouping) were compared with the control group, there were significant differences on all parameters: RNFL thickness, GCC thickness and CT (p < 0.05). CONCLUSIONS: RNFL and GCL were significantly thinner in the migraine patients with aura as compared with both the migraine patients without aura and the control subjects. In migraine, both with aura and without aura, patients' choroid thinning should be considered when evaluating ophthalmological findings.

The ocular endothelin system: a novel target for the treatment of endotoxin-induced uveitis with bosentan.

PURPOSE: We compared the anti-inflammatory effects of bosentan and dexamethasone in endotoxin-induced uveitis (EIU). METHODS: Endotoxin-induced uveitis was induced by subcutaneous injection of lipopolysaccharide (LPS, 200 µg) in Wistar rats. Rats were divided randomly into 10 groups (n = 6). Bosentan at doses of 50 and 100 mg/kg were administered orally 1 hour before and 12 hours after LPS injection, and dexamethasone was administered by intraperitoneally 30 minutes before and 30 minutes after LPS injection at a dose of 1 mg/kg. Data were collected at two time points for each control and treatment; animals were killed at either 3 or 24 hours after LPS injection. Histopathologic evaluation and aqueous humour measurements of TNF-α level were performed, and endothelin-1 (ET-1), inducible nitric oxide synthase (iNOS), and endothelin receptor A and B (EDNRA and B) expression were analyzed. RESULTS: The group treated with 100 mg/kg bosentan at 24 hours displayed significantly milder uveitis and fewer inflammatory cells compared to LPS-injected animals, and there were similar findings in the dexamethasone-treated group at 24 hours. The TNF-α levels in the dexamethasone treatment group were lower than those in the LPS-induced uveitis control group (P < 0.05); however, there was no difference between the dexamethasone and bosentan treatment groups at 3 and 24 hours after LPS administration. Bosentan treatment at doses of 50 and 100 mg/kg significantly decreased iNOS expression compared to LPS-injected animals (P < 0.001). The ET-1 expression was suppressed significantly by bosentan and dexamethasone at 3 and 24 hours after LPS administration (P < 0.001). The EDNRA expression in the bosentan treatment groups was statistically significantly lower than that in the LPS-induced uveitis control group at 3 and 24 hours after LPS administration (P < 0.05). CONCLUSIONS: Bosentan reduces intraocular inflammation and has similar effects as dexamethasone in a rat model of EIU.

Paintball-related ocular trauma: Paintball or Painball?

BACKGROUND: The aim of this study is to describe the type and severity of paintball-related ocular trauma and to determine the necessary precautions to minimize the risk of ocular injury regardless of whether adequate eye protection was used. MATERIAL AND METHODS: A retrospective chart review identified patients treated for paintball-related ocular trauma at the Ataturk University Medical Hospital from June 2010 through March 2013. A descriptive analysis of data was performed. RESULTS: Ten patients with paintball-related ocular trauma were identified. At the time of their first examination, 7 of these patients had visual acuity (VA) of 20/200 or worse. One patient had a final VA of no light perception and 4 patients had a final VA of 20/200 or worse. Hyphema was noted in 7 patients, traumatic cataract in 2, iridodialysis in 2, retinal detachment in 3, and secondary glaucoma in 1. Six patients required surgery. Although all victims have used eye protection during the game, all patients were injured after they thought the game was over and had taken off their helmets or eye-protective devices. CONCLUSIONS: Paintball-related accidents result in serious ocular trauma and most of the patients require surgery. These injuries result in severe loss of VA in some patients. Uninterrupted use of proper eye protection whenever a player is in the game field, even after they believe the game has ended, may reduce the incidence of severe ocular trauma in paintball players.

Comparison of the effect of W-shaped and linear skin incisions on scar visibility in bilateral external dacryocystorhinostomy.

BACKGROUND: The aim of this study was to compare the effect of W-shaped skin (WS) and linear skin (LS) incisions on cutaneous scar tissue formation in patients who have undergone bilateral external dacryocystorhinostomy. METHODS: Sixteen patients (14 females and two males) with acquired bilateral nasolacrimal duct obstruction were included in this prospective, interventional comparative study. LS incision was applied to one side and WS skin incision to the other side. The skin incisions were assessed 6 months after each procedure by the patients themselves and by two ophthalmologists who were unaware of the skin incision shape and side. Scar tissue that was not recognized under the same light conditions and in the same room from a 100 cm distance was recorded as grade 1. Minimally visible scar tissue was assessed as grade 2, moderately visible scar tissue as grade 3, and easily visible scar tissue as grade 4. RESULTS: The mean scar assessment scores recorded by the first ophthalmologist were 2.50±0.82 for the LS group and 1.25±0.45 for the WS group (P<0.001). The second ophthalmologist's assessment scores were 2.25±0.86 for the LS group and 1.25±0.45 for the WS group (P<0.001). The mean patient self-assessment score for the incision scars was 2.44±1.03 for the LS group and 1.56±0.73 for the WS group (P<0.001). CONCLUSION: Compared with LS incision, WS incision resulted in less cutaneous scar tissue formation in patients who have undergone bilateral external dacryocystorhinostomy.

The use of polypropylene suture as a frontalis suspension material in all age groups of ptosis patients.

PURPOSE/AIM: To evaluate the use of 2-0 polypropylene suture for frontal suspension in ptosis patients with poor levator function. MATERIALS AND METHODS: This retrospective study included 20 eyelids of 16 patients (5 female, 11 male) with 4 mm or less levator function. The operation was considered successful when the difference between the two upper lids was ≤ 1 mm, and the upper lid covered the upper limbus by <3 mm. RESULTS: Median patient age was 22.94 years (2 to 59). Mean follow-up time was 18.06 months (12-29). A successful result was obtained in 14 patients (87.5%). Ptosis recurrence was observed in two patients (12.5%). Lagophthalmos with punctate epithelial keratitis and subsequent spontaneous recovery occurred during the first postoperative week in six patients (37.5%). Two patients with hypocorrection underwent revision surgery in the first postoperative week. Granuloma and material exposition at the forehead incision site observed in one patient at the postoperative fifth month were repaired by excision of the granuloma and suture reposition. CONCLUSIONS: Polypropylene suture as a frontalis suspension material in ptosis patients with poor levator function maintained satisfactory results at follow-up. This material allows easy and repeatable eyelid height adjustment and does not obviate future eyelid procedures.

Oculogyric crisis in a patient taking metoclopramide.

Oculogyric crisis is an acute dystonic reaction of the ocular muscles characterized by bilateral dystonic elevation of visual gaze lasting from seconds to hours. This reaction is most commonly explained as an adverse reaction to drugs such as antiemetics, antipsychotics, antidepressants, antiepileptics, and antimalarials. Although the incidence of metoclopramide-induced acute dystonic reactions has been reported as 25% in children, there have been few published cases on oculogyric crisis in general. It is important to be able to recognize this ocular side effect because, without a thorough patient history, symptoms can be confused with other diseases such as versive seizures, paroxysmal tonic upward gaze, and encephalopathy. In this paper, we report a case of oculogyric crisis induced by metoclopramide.
