A 60 year old farmer presented on 4th Sept, 2015with progressive diminution of vision in the right eye following trauma while hammering about a month previously. His vision was Hand Movement only in the right eye and 6/6 in left eye. The anterior segment showed normal findings, except mild anterior chamber reaction and an early cataract in the right eye. The left eye was normal except for an early age-related cataract. Fundoscopy revealed retained intra-ocular foreign body (ROOFB, subtotal RD with macula off in right eye. Interestingly, no entry wound was found. A B-scan and CT scan of the brain and orbit confirmed RIOFB and RD. On 9th September 23G PPV was done and RIOFB was removed. Fluid-air exchange, endolaser and silicon oil injection were done to attach the RD. On 6th February 2016 a cataract extraction with intraocular lens implantation and silicon oil removal was performed which improved the patient’s vision to 6/18p.

It has been suggested that the practice of meditation is associated to neuroplasticity phenomena, reducing age-related brain degeneration and improving cognitive functions. Neuroimaging studies have shown that the brain connectivity changes in meditators. In the present work, we aim to describe the possible long-term effects of meditation on the brain networks. To this aim, we used magnetoencephalography to study functional resting-state brain networks in Vipassana meditators. We observed topological modifications in the brain network in meditators compared to controls. More specifically, in the theta band, the meditators showed statistically significant (p corrected = 0.009) higher degree (a centrality index that represents the number of connections incident upon a given node) in the right hippocampus as compared to controls. Taking into account the role of the hippocampus in memory processes, and in the pathophysiology of Alzheimer’s disease, meditation might have a potential role in a panel of preventive strategies.

AbstractThe frontal lobes, if damaged, may lead to a host of divergent abnormalities, depending on the extent, site, depth, and laterality of the damage. Because of the extensive connections which exist between the frontal lobes and the other systems of the brain, damage to a more remote system may cause frontal system disorder through disconnection. The Hand Movement Test (HMT, Kaufman & Kaufman, 1983) is thought to be sensitive to damage affecting these systems, although the test was developed for use with children rather than adults. This paper examines the effects of three diverse neuropsychological disorders, where damage to the frontal lobes or to their interconnections has been implicated, on hand movement sequencing performance in adults. The three groups studied included patients diagnosed with alcohol-related brain damage (n = 57), patients diagnosed with mild traumatic brain injury (n = 21), and patients diagnosed with age-related dementia (n = 30). HMT performance was significantly poorer in all three clinical groups relative to controls, supporting the addition of this brief, paediatric test in neuropsychological evaluations assessing these disorders.

This paper provides the first reported case of acute posterior chamber hemorrhage during fluorescein angiography (FA). This is a case review with serial color photographs of the anterior segment. A 76-year-old male was referred for angiographic control of age-related macular degeneration. He was pseudophakic OU, BCVA 20/40 OU. He had mild hypertension, but not diabetes. He had had two previous angiograms without adverse effects. Difficulty was experienced in obtaining the images owing to a progressive reduction in the transparency of the media. A dense hemorrhage in the posterior chamber of the right eye was found, involving the visual axis. Thorough biomicroscopy, gonioscopy, and ultrasonic biomicroscopy showed that part of one of the haptics of the right intraocular lens (IOL) was touching and tearing the posterior face of the iris, without any visible synechiae, iris, or angle neovascularization. Anterior segment FA and posterior ultrasonography were normal. No similar case has been described in the literature involving dense progressive bleeding located in the capsular bag and posterior chamber, without any detectable triggering ocular event other than mydriasis and fluorescein injection. Contact of the iris or sulcus with part of the intraocular lens, aggravated by the intense use of mydriatics during the FA procedure, probably caused bleeding to happen.

Report a clinical presentation of patient with rhematogenous retinal detachment by viterectomy and high myopia with C3F8 gas tamponade. A 20-year-old female came into the outpatient clinic with blurry vision on the right eye as her chief complaint. It had been happening since 1 month ago. In examination, we found result of visual acuity RE 1/300 and LE 1/60 correction Sferis-16.00 5/7.5, anterior segment in a normal range. In posterior segment evaluation, there were RE detachment on 3-11 o’clock position and hole on 6 and 8 o’clock position. Then we performed vitrectomy and  C3F8 gas tamponade. The first day after surgery, we found IOP 19,6 mmHg and Von Herrick III. Then after the second day, we found a pain on the right eye, TIO 47.3 mmHg, Von Herrick 0 and opaque lens. Then we performed iridectomy and intravitreal gas aspiration. After it were done, we found IOP 17.3 mmHg and Von Herrick 0. In anterior segment OCT evaluation, we found a narrow angle anterior segment. Then we planned to do a cataract extraction with using viscoelastic to perform the anterior chamber.Malignant glaucoma can occur in cases after vitrectomy action due to aqueous misdirection and emphasis on gas expansion on tamponade. Cataract extraction and gas aspiration can help open the anterior chamber and the intraocular pressure returns to normal

Firecracker induced open globe injury is a big challenge for ophthalmic surgeons. Its associationwith the intraocular foreign body makes the diagnosis and treatment even more difficult resultingin poor anatomical and visual outcomes. We report a case of a 35-year-old male who presented withbilateral, multiple corneal and intraocular foreign body due to firecracker explosion. His vision waslimited to hand movement in both eyes. Combined penetrating keratoplasty and cataract surgerywere done in both eyes followed by pars plana vitrectomy for intraocular foreign body removal.The final best-corrected visual acuity of the patient stood to be 6/6 and 6/9 in the right and left eyerespectively. The encouraging result in our case prompts ophthalmologists for a timely stepwisemultidisciplinary approach in all open globe injuries with intraocular foreign body cases havingpoor initial acuity.

Management of low vision in pediatric patients with greater result can affect their quality of life than in adult low vision patients. Retinopathy of prematurity is the main cause of blindness in children. A case study highlights the tertiary prevention (low vision examination and management) in a 5 year old boy with ROP related blindness to optimize his remaining visual capacity by using optical and non-optical aids that support daily activity and educational learning. A 5-year-old boy with ROP related blindness visited to the low vision clinic after receiving the several treatments for ROP before. His visual acuities were light perception in the right eye and hand movement in the left eye using his current spectacle correction. He had anti VEGF bevacizumab intravitreal injection, vitrectomy and complicated cataract extraction history on the left eye. He was difficult to learn and read numbers and alphabets caused by visual impairment. Upon evaluation by assessment low vision method, his distance visual acuity in the left eye was improved significantly up to 3/40 on LEA Acuity chart with +14.00D. His near vision became 10 M at 30 cm of reading distance (without near correction) and 4 M at 13 cm improved with +3.00 D by spectacle. The non-optical aid devices as reading task were also suggested to improve continuous reading text without difficulty. ROP blindness can be preventable if appropriate, adequate and accessible screening programmes are available. Unfortunately, even with the current screening guidelines and recommended treatment of ROP, many babies suffer from blindness by this disease each year. Low vision assessment and management in pediatric patient with visual impairment according to children need can optimize the recent visual capability of low vision patient and give selfcare daily activity and educational learning.

Nail Gun Injury

A 30-year-old man walked into the emergency department after a suicide attempt by firing a nail from a pneumatic nail gun directed at his left temple. He was haemodynamically stable and neurologically intact, able to recall all events and moving all extremities with a Glascow Coma Scale of 15. CT of the brain showed a 6.3 cm nail in the right frontal region without major intracerebral vessel disruption. He was taken to the operating room for left temporal wound washout, debridement of gross contamination and closure with titanium cranial fixation plate. The foreign body was not accessible on initial surgical intervention and was left in place to define anatomy and plan for subsequent removal. Thin slice CT images were used to create 3D reconstructions to facilitate stereotactic navigation and foreign body removal via right craniotomy the following day. The patient tolerated the procedures well and recovered with full neurological function.

An 80-year-old male was referred to our hospital for chronic bullous keratopathy in the right eye. Ten years before, he was affected by an attack of primary acute angle closure glaucoma in high hyperopia and Fuchs’ endothelial dystrophy. A bilateral iridotomy was performed. Thereafter, the patient developed an endothelial decompensation in the left eye, and, in another hospital, he underwent an open-sky combined cataract extraction and penetrating keratoplasty. Our surgical approach for the right eye consisted of phacoemulsification and, after 1 month, a Descemet’s stripping automated endothelial keratoplasty (DSAEK). After the procedure, an interface fluid was suspected, and an anterior segment optical coherence tomography (OCT) confirmed it. The graft was well centered but thickened, showing no movement in the anterior chamber, adherent to the periphery of the recipient cornea but with a pool of fluid in the center. Seven days postoperatively, an anterior segment OCT showed initial signs of reabsorption of the fluid. On day 45, the graft was adherent with normal thickness and the interface fluid had completely disappeared. The corneal stroma was clear, but a faint interface opacity appeared and is still present. We obtained a good surgical result and best corrected visual acuity was 7/10 at postoperative month 4. No further surgical procedures are scheduled.

Introduction. Penetrating injury is characterized by the existence of entry wound only, and it can be with or without an intraocular foreign body (IOFB). IOFB can lead to a mechanical injury of the eye and to cause infection or to manifest other toxic effects on intraocular structures. Iron and copper can dissolve and cause siderosis, i.e. chalcosis of the eye. Ocular siderosis is diagnosed by clinical and electroretinogram (ERG) findings. Outline of Cases. The first patient was a 37?year?old male who was injured by a metal foreign body. He presented at the Clinic two years after the injury. Visual acuity of the right eye (VOD) on admission was VOD=L+P+ (light projection). Pars plana phacovitrectomy with IOFB extraction was done. Visual acuity on discharge was VOD=3/60 cc + 7.50 Dsph=0.2. The second patient was a 55?year?old male who presented at the clinic 18 months after injury. On admission visual acuity in his left eye was VOS 1/60. Pars plana phacovitrectomy with IOFB extraction was done. Visual acuity on discharge was VOS=0.7 through the stenopeic slit. Conclusion. In penetrating injuries caused by a metal IOFB pars plana vitrectomy with IOFB extraction is indicated. In cases with IOFB, when visual acuity is preserved, the lens is transparent, while the eye is without signs of infection, urgent pars plana vitrectomy is not necessary. Such patients need regular follow?up with obligatory ERG findings.
