RESUMEN
BACKGROUND: The aim of this study was to assess the intraocular pressure and ocular biometric parameters in migraine patients during acute migraine attacks and compare them with painless period and healthy controls using a new optical biometer AL-Scan. METHODS: In this prospective, case-control study, the axial length, corneal curvature radius, anterior chamber depth, central corneal thickness, and pupil size of 40 migraine patients during acute migraine attacks and painless period and 40 age- and sex-matched healthy subjects were measured using a AL-Scan optical biometer (Nidek Co., Gamagori, Japan). All patients underwent a complete ophthalmic examination before the measurements. IOP and biometer measurements were taken at the same time of day (10:00-12:00) in order to minimize the effects of diurnal variation. RESULTS: There was not a statistically significant difference in intraocular pressure between the migraine patients during acute migraine attacks (15.07 mmHg), painless period (14.10 mmHg), and the controls (15,73 ± 0,81). Also, the ocular biometric parameters did not significantly vary during the acute migraine attacks. CONCLUSIONS: Further studies are needed to evaluate the etiopathologic relationship between intraocular pressure and ocular biometric parameters and acute migraine attack.

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.
RESUMEN
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.

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.

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.

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.

PURPOSE: This study aims at comparing two different types of drainage tubes in conjunctivodacryocystorhinostomy, which are used for upper lacrimal system obstruction or damage, with respect to their respective postoperative problems and solutions. METHODS: Nineteen eyes of 17 patients who underwent conjunctivodacryocystorhinostomy (CDCR) or conjunctivorhinostomy (CR) surgery with a Medpor coated tear drainage tube or silicon tube placement between October, 2010, and February, 2014, were included in this retrospective comparative study. RESULTS: In the initial surgery, Medpor coated tear drainage tubes were used in 11 eyes by CDCR, whereas silicon tear drainage tubes were implanted into 2 eyes by CR and 6 eyes by CDCR. In group 1, proximal and distal obstructions developed postoperatively in 4 eyes, while 1 eye showed tube malposition and 3 eyes developed luminal obstruction by debris 3 times. In group 2, tube extrusion developed in 4 eyes, whereas tube malposition developed in 6 eyes and luminal obstruction by debris developed in 6 eyes at different times, for a total of 20 times. CONCLUSIONS: In our study, the most significant complication we observed in the use of silicon tear drainage tubes was tube extrusion,whereas the leading complication related to the use of Medpor coated tear drainage tubes was tube obstruction.

OBJECTIVE: To determine the effect of "W incision" instead of classical vertical incision at external DCR on scar formation. MATERIALS AND METHODS: Patients with acquired nasolacrimal duct obstruction (NLDO) who were treated with external DCR with classical vertical incision, and patients who were treated with external DCR with "W incision" were included in the study. The first 39 eyes were operated with a vertical incision, and the remaining 37 eyes were operated with a "W incision". All the skin incision scars of the patients were assessed and scored by at least the 6th month. The assessment was made by both the patients themselves, and by an ophthalmologist other than the surgeon himself, each scored the incision scar separately (single-masked study). Scores for both groups were compared, and statistical analyses were performed. RESULTS: Self-assessment scores for the incision scar were Grade 2.28 ± 0.94 in the Vertical incision group, and Grade 1.68 ± 0.57 in the "W incision" group (p < 0.01). The "W incision" scar formation was significantly less noticable than the Vertical incision scar formation. Similarly, the assessment scores of the ophthalmologist other than the surgeon himself were significantly lower for the "W incision" group than for the Vertical incision group. The mean scar assessment scores were Grade 2.13 ± 0.95 in the Vertical incision group, and Grade 1.57 ± 0.68 in the "W incision" group (p < 0.01). CONCLUSION: Skin scar tissue was found to be significantly reduced with a "W incision" in external DCR operations.

PURPOSE: This study applies treatment methods to rat retinas subjected to acute ischemia reperfusion injury and compares the efficacy of memantine, hyperbaric oxygen (HBO) therapy, and brimonidine by histopathological examination. METHODS: Thirty adult Wistar albino rats were divided into five groups after retinal ischemia was induced by elevating the intraocular pressure to 120 mmHg. The groups were as follows: group 1: control; group 2: acute retinal ischemia (ARI) model but without treatment group; group 3: memantine (MEM) treatment group; group 4: HBO therapy group; and group 5: brimonidine treatment (BRI) group. In the control group, right eyes were cannulated with a 30-gauge needle and removed without causing any intraocular pressure change. The ARI group was an acute retinal ischemia model, but without treatment. In the MEM group, animals were given a unique dose of intravenous 25 mg/kg memantine by the tail vein route after inducing ARI. In the HBO group, at 2 h following ARI, HBO treatment was applied for nine days. In the BRI group, a 0.15% brimonidine tartrate eye drop treatment was applied twice a day (BID) for seven days before ARI. Twenty-one days after establishing ischemia reperfusion, the right eyes were enucleated after the cardiac gluteraldehyde perfusion method, and then submitted to histological evaluation. RESULTS: On average, the total retinal ganglion cell number was 239.93 ± 8.60 in the control group, 125.14 ± 7.18 in the ARI group, 215.89 ± 8.36 in the MEM group, 208.69 ± 2.05 in the HBO group, and 172.27 ± 8.16 in the BRI group. Mean apoptotic indexes in the groups were 1.1 ± 0.35%, 57.71 ± 0.58%, 23.57 ± 1.73%, 15.63 ± 0.58%, and 29.37 ± 2.55%, respectively. CONCLUSIONS: The present study shows that memantine, HBO, and brimonidine therapies were effective in reducing the damage induced by acute ischemia reperfusion in the rat retina. Our study suggests that these treatments had beneficial effects due to neuroprotection, and therefore may be applied in clinical practice.

Tonometry is one of the basic diagnostic tests used for the diagnosis of glaucoma and uveitis in veterinary ophthalmology. The Icare® Rebound Tonometer which is a new tonometric device has been shown to be useful in a wide range of species. Eyes (n = 48) of 24 Simmental and Montafon calves with a mean age of 7.5 weeks (2-16 weeks), male and female, were subjected to intraocular pressure (IOP) measurement using the Icare® Rebound Tonometer with calves standing and in lateral recumbency. The mean IOP was measured as 9.02 ± 2.38 mmHg in the right eye and 9.08 ± 2.55 mmHg in the left eye. No age-related change was found in intraocular pressure of the calves between 2 and 16 weeks of age. No difference in IOP values was observed between Simmental and Montafon calves. Body position had no effect on IOP in calves. The Icare® Rebound Tonometer was shown to be a suitable diagnostic device for IOP measurement in calves.

PURPOSE: To evaluate the clinical outcomes of maximal levator muscle resection surgery in patients with poor levator function. METHODS: This prospective study included 29 eyelids of 23 patients who underwent maximal levator resection surgery. Pre- and postoperatively, all patients' routine ophthalmic examination including evaluation of upper eyelid skin crease positions; levator muscle function (LF), rima palpebrarum (RP), and margin-reflex distance (MRD) measurements were recorded. Outcome was considered successful when the difference between the two upper eyelids was ≤1 mm; if the difference between the two eyelid margins was more than 1 mm and less than 2 mm, it was considered to be satisfactory. More than 2 mm difference was considered to be poor. RESULTS: Mean patient age was 11.3 ± 8.6 years (3 months to 24 years). Mean follow-up time was 22.8 ± 6.9 months (10 to 36 months). Preoperatively mean RP, MRD, and LF measurements were 5.5 ± 1.7 mm, -0.14 ± 1.6 mm, 2.5 ± 1.4 mm (0-4 mm), respectively. Preoperatively, eight (27,6%) patients had skin crease. Abnormal head posture was detected in eight (34.8%) of the patients. Postoperatively, RP, MRD, and LF values increased significantly (p < 0.05). Mean RP, MRD, and LF measurements were 8.3 ± 1.5 mm, 2.6 ± 1.2 mm, 5.1 ± 2.1 mm, respectively. Fourteen subjects (60.9%) had successful results, two subjects (8.7%) had satisfactory results, and seven subjects (30.4%) had poor results. Abnormal head postures of all patients were resolved. CONCLUSIONS: Maximal levator resection may be a good alternative method to frontalis suspension in congenital blepharoptosis patients with poor levator function.

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.
RESUMEN
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.
RESUMEN
PURPOSE: To evaluate of functional and cosmetic effectiveness of lower eyelid sling technique with fascia lata graft in patients with lagophthalmos due to facial paralysis. MATERIAL AND METHOD: Ten patients with a mean age of 55.1 ± 19.77 years who underwent lower eyelid sling surgery with a fascia lata graft between September 2011 and January 2014 were included in this prospective study. Preoperatively and postoperatively patients were evaluated in terms of corneal epithelial defects, Schirmer's test, and tear break-up time (TBUT). Cosmetically, vertical eyelid aperture, margin reflex distances 1 and 2 (MRD1 and MRD2) and scleral show were evaluated preoperatively and postoperatively. RESULTS: One patient had facial paralysis on the right side whereas the other 9 patients had facial paralysis on the left side. Preoperatively, 3 patients were detected with corneal ulcer, whereas 7 patients were detected with persistent corneal epithelial defects localized in the lower half of the cornea. In the 3 patients with preoperative corneal ulcer, the ulcer recovered with corneal opacity, whereas in the 7 patients with punctate epitheliopathy, postoperative corneal transparency was obtained. DISCUSSION: Lower eyelid sling technique with fascia lata graft is an effective technique for the repositioning of the lower eyelid and preventing the corneal complications.

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.
RESUMEN
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.

AIM: To report a case of cilioretinal artery occlusion (CRAO) with central retinal vein occlusion (CRVO) after a journey to high altitude region and the use of late period hyperbaric oxygen (HBO) therapy successfully. CASE REPORT: A previously healthy 48-year-old lowlander woman was admitted to our department for sudden blurred vision in her right eye started at 2 weeks prior to examination. The patient had a history of 1-month exposure to high altitude that finished a day before the onset of her complaints. The best corrected visual acuity (BCVA) was 10/20 in the right eye (RE) and 10/10 in the left eye. Fundus examination of the RE revealed whitening of the retina along the distribution of cilioretinal artery, sparing fovea, flame-shaped hemorrhages, and roth spots with minimally dilated and tortuous retinal veins. Visual field analysis revealed centrocecal scotoma. The patient was treated by a daily session of 2 h of HBO at 2.5 atmosphere absolute for 11 days. BCVA rised to a level of 20/20 for the RE and the scotomas were disappeared immediately after using of the HBO treatment. CONCLUSION: CRVO related CRAO should be regarded as a rare complication of exposure to high altitude and HBO seems to be the treatment of choice of high altitude related co-occurence of CRVO and CRAO in the late period.

Purpose. The aim of this study is to investigate the etiology and the clinical, microbiological, histopathological, and radiological findings of acquired dacryocystoceles. Methods. In this retrospective study, we reviewed the clinical records of 10 eyes of 8 patients with dacryocystoceles who underwent external dacryocystorhinostomy (DCR) surgery. Etiology, presenting symptoms and radiological findings as well as microbiological and histopathological assessment results and outcome were analyzed. Results. The records of 8 patients with dacryocystoceles were included in this study. In the histopathological evaluations of the samples collected from the lacrimal sac wall, chronic inflammation was found in all biopsied samples and fibrosis was observed in two histopathological evaluations. Computerized tomography (CT) imaging showed fluid collection separated from adjacent tissues by a thin rim, corresponding to dacryocystoceles in the sac. In the microbiological culture examination of samples collected from the fluid within the cyst, no bacterial growth in 5 eyes, gram-negative bacillus growth in 3 eyes, and gram-positive cocci growth in 2 eyes were found. Conclusions. Acquired dacryocystoceles were observed extremely rarely and a definite pathogenic agent could not be identified in any of the cases, either microbiologically or histologically, whereas chronic inflammation was detected in all cases in our study.
RESUMEN
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.
