OBJECTIVEIn tuberculum sellae meningioma (TSM) surgery, endonasal approaches are claimed to have a superior visual outcome compared with transcranial approaches. The authors question whether this is always true and analyze their series of cases of endoscope-assisted transcranial TSM surgery with special regard to the postoperative visual outcome in order to explore this issue.METHODSAll surgical procedures for TSM performed between 2003 and 2015 in the Department of Neurosurgery, University Medicine Greifswald, were retrospectively analyzed. Special attention was paid to the postoperative visual outcome.RESULTSDuring the study period, 15 patients (12 female and 3 male) underwent surgery for TSM. Gross-total resection was achieved in 14 cases (93.3%) and near-total resection in 1. One patient suffered from a major stroke during surgery and had to be excluded from further analyses. No other complications occurred. Preoperatively, visual acuity was disturbed in 12 patients (80%) and visual field deficits were present in 11 patients (73.3%). In 3 patients (20%), the TSM was an incidental finding. Postoperatively, ophthalmological examination revealed an improvement of visual acuity in 10 (90.9%) of 11 patients and improvement of visual field deficits in 9 (90%) of 10 patients; no deterioration of visual acuity or visual field was seen in any patient. Visual acuity and visual field improvement was observed in all patients who had surgery within 3 years after the onset of visual disturbances. No tumor recurrence was observed during follow-up (mean 32 months, range 3–134 months). TSMs were approached via a frontolateral craniotomy in 7 patients and via a supraorbital craniotomy in 8. The use of the endoscope as an assistive device led to improved tumor visualization and consequent removal in areas that were hidden in the microscopic view in 6 patients (40%).CONCLUSIONSThe present series confirms a favorable visual outcome after TSM surgery via supraorbital or frontolateral endoscope-assisted approaches. With endoscopic visualization, major manipulation of the optic apparatus could be avoided, perhaps affecting the favorable visual outcome.

We report our experience on the treatment of tuberculum sellae meningiomas (TSMs) regarding the involvement of the optic canal and clinical outcomes. We reviewed 23 patients who were operated on between January 1997 and December 2008. The surgical approach was unilateral subfrontal supraorbital osteotomy in one piece. Attempts were made to improve visual function via extra/intradural unroofing of the optic canal, which released the optic nerve. Visual symptoms were present preoperatively in 21 patients, and two patients were asymptomatic. Visual acuity remained intact in 6 patients, improved in 10, was unchanged in 5 patients, and worsened in 2 patients. The postoperative visual field was normal or improved in 17 patients, unchanged in four patients, and worsened in two patients. The optic canal and clinoid were drilled extradurally in eight patients and intradurally in nine patients. Total resection of TSMs was achieved in 19 patients. Incomplete resection occurred in two patients. Decompression of the optic canal seemed to increase the visual outcome.

Background/aimsTo determine the mortality within 20 years of diagnosis of chronic open-angle glaucoma (COAG) and visual acuity and visual field progression of a cohort followed for 20 years.MethodsTwenty years following the diagnosis of COAG in 68 of 436 (16%) patients seen in a glaucoma case-finding clinic, visual and mortality outcomes were audited from medical records. Causes of death were obtained from general practitioner records and death certificates. Probability of death was calculated using a Kaplan-Meier survival curve. The visual field of each eye of survivors was graded using a nine-stage severity scale. Visual outcome was analysed at the 20-year follow-up visit.ResultsFrom 68, 14 (21%) were lost to follow-up. In the remaining 54, 20 (37%) were alive 20 years after diagnosis. Of 63% who died, mean age of death was 84 years, most commonly due to vascular disease. Mean age at presentation of those who died was 73.7 years versus 63.2 years for survivors (P=0.001). The median time to death was 16 years. On visual field analysis, nearly half (48.9%) of eyes did not deteriorate, but 28.3% eyes deteriorated by more than two stages. Those who died had worse final visual acuity than survivors (P<0.001). Three who died were registered severely visually impaired mainly from macular disease, but no survivors were registered (P<0.001).ConclusionIn this cohort, approximately two-thirds of patients with glaucoma died within 20 years of diagnosis. In most older patients with glaucoma, the overall goal of preventing visual handicap and blindness is achievable 20 years after diagnosis.

Appropriate medical management can be an alternative in those patients with submacular cysticercosis in whom achieving good visual outcome with vitreoretinal surgery is not possible. We report the case of a 25-year-old female who presented complaining of blurred vision in her left eye associated with photopsias and metamorphopsias of 3 months duration. Initial visual acuity in the right eye was 20/20 and 20/100 in the left eye. Upon indirect ophthalmoscopy in the left eye, a yellow-white, dome-shaped, elevated lesion with foveal involvement was observed. The rest of the ophthalmological examination proved normal. With clinical findings and images, submacular cysticercosis was diagnosed, and vitreoretinal surgery was suggested. Nevertheless, the patient did not accept the treatment; therefore, medical management was initiated. Central nervous system involvement was ruled out, and treatment with praziquantel and systemic prednisolone was initiated. Cysticercosis was resolved with significant improvement of her symptoms and visual acuity.

Background: A paradoxical discrepancy between severe peripapillary retinal nerve fiber layer (pRNFL) atrophy and good visual outcome had been reported in patients with myelin oligodendrocyte glycoprotein-immunoglobulin G (MOG-IgG)-associated optic neuritis (ON). However, only visual acuity (VA) was assessed. Objectives: To study visual field (VF) outcomes of patients with MOG-IgG-associated ON and evaluate the correlation between functional eye outcome and retinal structural changes assessed by optical coherence tomography. Methods: The records of 32 patients with MOG-IgG-associated ON who underwent ophthalmological examination at least 12 months after ON onset were reviewed. Degree of VF disability was determined by mean deviation (MD). Results: At final assessment (median, 35 months), 4.2% of 48 affected eyes (AE) had VA ⩽ 0.1, 40% had abnormal MD, and among AE with final VA ⩾ 1.0, 31% had mild to moderate damage. Thinning of the inner retinal layers was significantly correlated with MD impairment. Analysis demonstrated a threshold of pRNFL thickness (50 µm), below which MD was significantly worse (mean, −2.27 dB vs −17.72 dB; p = 0.0003). ON relapse was significantly associated with poor visual outcome assessed by MD. Conclusion: Functional impairment measured with VF is not rare, and MD assessment better reflects actual structural damage.

BackgroundThe neuro-ophthalmological manifestations of Behcet’s disease (BD) are rare, and data regarding their characteristics and outcome are lacking.ObjectiveTo report prevalence, main characteristics and outcome of neuro-ophthalmological manifestations in BD.Patients and methodsThis is a retrospective monocentric study of 217 patients diagnosed with neuro-Behçet’s disease (NBD), of whom 29 (13.3%) patients presented with neuro-ophthalmological manifestations (55% of men and mean±SD age of 26±8 years). All patients underwent a detailed ophthalmological examination and were followed up in the internal medicine and the ophthalmology departments.ResultsNeuro-ophthalmological manifestations were the first presentation of BD in 45% of patients and developed later in the course of the disease in 55% of patients. They are divided into parenchymal (PM) and non-parenchymal (NPM)-related manifestations in, respectively, 13 patients (45%) and 16 patients (55%). PM included papillitis in seven patients (53.8%), retrobulbar optic neuritis in four patients (30.8%) and third cranial nerve palsy in two patients (15.4%). NPM included papilloedema related to cerebral venous thrombosis in all 16 patients, of whom 6 patients (37.5%) had sixth cranial nerve palsy. At initial examination, 93.1% of patients had visual alterations, including mainly decreased visual acuity visual field defects and/or diplopia. All patients were treated with corticosteroids and 79% of patients received immunosuppressive agents. After treatment, the visual outcome improved or stabilised in 66.7% of patients while it worsened in 33.3. The mean±SD logarithm of the minimum angle of resolution visual acuity improved from 0.4±0.3 at diagnosis to 0.2±0.3 after therapy. 10.3% and 3.4% of patients were legally blind at diagnosis and after therapy, respectively.ConclusionNeuro-ophthalmological manifestations of BD represented 13% of NBD. They could be potentially severe and disabling. Prompt treatment is the key factor in improving visual outcome.

Thyroid optic neuropathy is one of the most troubling complications of endocrine ophthalmopathies. It is related to the degree of extraocular muscle swelling in the apex of the orbit. The purpose of this study was to investigate contrast sensitivity and visual-field thresholds in patients with thyroid optic neuropathy. We examined twenty-two patients aged 29 – 63 years (mean 45.3 years). The control group consisted of fifteen healthy persons of similar age. Contrast sensitivity was measured by means of Volkov's charts (sinusoidal gratings) at eight spatial frequencies from 17.5 to 0.46 cycles deg−1. The visual field was investigated with a static automatic perimeter (Allgan Humphrey Field Analyzer) by means of the central 30-2 threshold test. All patients underwent a complete ophthalmological examination including best corrected Snellen visual acuity, fundus copy, and proptosis measurement with the Hertel exophthalmometer. The mean proptosis of patients was 19.4 mm. Fifteen of the patients had decreased visual acuity. Contrast sensitivity at low spatial frequencies was significantly reduced in the patients. It was established that a reduction of visual-field threshold accompanies the decrease of visual acuity. Our results show that contrast sensitivity and visual-field threshold testing are very sensitive at detecting early optic neuropathy and may be a useful means of following patients after treatment.

AIM: To identify the clinical features and treatment outcomes of endogenous Klebsiella pneumoniae endophthalmitis and investigate prognostic factors of poor visual outcome. METHODS: The clinical records of all patients diagnosed with endogenous Klebsiella endophthalmitis between January 2007 to December 2018 in Prince of Wales Hospital, Hong Kong, China were retrospectively reviewed. Thorough ophthalmological examination findings were recorded in the case note, including visual acuity testing, slit-lamp examination, indirect ophthalmoscopy and B-scan ultrasonography if media opacity precluded fundus viewing. RESULTS: A total of 18 eyes in 14 patients were identified. Bilateral involvement was noted in 4 patients (28.6%). Hepatobiliary sepsis was the source in 9 patients (64.3%). Culture of intraocular fluid was positive in 5 out of 18 eyes (27.8%). Mortality was noted in 2 patients (14.3%). Mean final visual acuity was 20/1500. Six out of 16 eyes had total loss of sight (37.5%) and 3 eyes required evisceration (18.8%). Multivariate linear regression revealed poor presenting visual acuity (P=0.031) and lack of fundus view due to vitritis (P=0.02) as prognostic factors of poor visual outcome. CONCLUSION: Visual outcome of endogenous Klebsiella endophthalmitis is poor. Poor presenting visual acuity and lack of fundus view predict poor visual outcome. High index of suspicion for endophthalmitis is important in Klebsiella sepsis patients with complaints of ocular symptoms. Ophthalmological screening is recommended in non-communicable patients with Klebsiella sepsis.

The aim of this study was to evaluate (surgical) visual outcomes in patients treated via supraorbital keyhole eyebrow incision approach. Data from 14 patients with TSMs (Tuberculum Sellae Meningioma) who underwent microsurgical treatment by a supraorbital keyhole eyebrow skin incision between September 2006 and September 2013 were retrospectively collected and analyzed. Patients were analyzed on the basis of clinical, radiological, and surgical factors that appeared to affect the outcome. To quantify the extent of ophthalmological disturbances Visual impairment score was used to analyze visual acuity and visual fields, which range from 0 (best) to 100 (worst). Change in visual function was assessed as the main outcome. The mean age of the 10 women and 4 men enrolled in the study was 56.50years (range, 42~74 years). The presenting symptom was asymmetrical visual loss in 71.4% of the patients.And examination revealed decreased visual acuity (Snellen notation) in 100% and impaired visual fields (Goldmann perimetry) in 58.3 % (7/12 cases, central scotoma and temporal anopia n=1, classical bitemporal hemianopia n=4, incongruent homonymous hemianopia n=2 , 2 cases data N/A) of the patients. Simpson grades I resection via a supraorbital keyhole eyebrow skin incision approach, were achieved in 100% of the patients. Quality of life was assessed according to Karnofsky scale and was 86.67 (range: 70~100). The mean follow-up duration was 51.73 months (range: 27~91 months).No recurrent tumors were observed during this period. According to the findings of this study, this approach provides a pleasing cosmetic outcome and also decreases brain manipulation while minimizing the likelihood of procedure-related morbidity. A favorable visual outcome was observed in most of the patients in the late postoperative period. Nepal Journal of Neuroscience, Volume 14, Number 3, 2017, page : 26-32

Abstract Background: It is uncommon to see retinitis pigmentosa in keratoconus patients. The main difficulty of visual rehabilitation for this is restricted visual field. We presented the treatment and gene screen of visual system homeobox 1 (VSX 1) gene in this case. Case presentation: A 24-year-old man with retinitis pigmentosa presented with progressively blurred vision. Slit lamp examination revealed Vogt’s striae over both eyes, and corneal topography indicated bilateral keratoconus. We had tested 5 exons of VSX 1 gene from him and the did not find mutation on direct sequence. To improve visual acuity, we prescribed keratoconus rigid gas permeable (RGP) contact lens for him with good efficacy. However, lens dislocation occurred occasionally. He could not find dislocated lens easily due to visual field restriction, so he asked for more stable visual aids. Therefore, we instead prescribed scleral lens (SL), which were more stable on the ocular surface and led to more stable vision. Visual acuity was also gained with SL, but the tolerance time for SL was shorter compared to that of keratoconus RGP contact lens. To compare the efficacy of these two lenses, we surveyed life quality using the National Eye Institute Visual Functioning Questionnaire – 25 in three situations: baseline, with keratoconus RGP contact lens, and with SL. Conclusion: The patient used the two lens types according to his needs, and benefited from vision rehabilitation with both keratoconus RGP contact lens and SL. Keywords: keratoconus; retinitis pigmentosa; rigid gas permeable contact lenses; scleral lenses.

Background/aimsIt remains unclear whether the presence of optic disc haemorrhages (ODH) or cotton wool spots (CWS) at presentation in patients with papilloedema from idiopathic intracranial hypertension (IIH) has prognostic value. The aim of this study was to determine if optic disc appearance at presentation predicts visual outcome in patients with IIH.MethodsRetrospective study of 708 eyes of 360 consecutive patients with IIH who had baseline optic disc photographs before or within 30 days of their diagnostic lumbar puncture and initiation of medical treatment. Optic disc photographs were independently graded by three ophthalmologists in a standardised manner. Visual function was assessed using Snellen converted to logMAR visual acuity, Humphrey mean deviation and visual field grade.ResultsAt least one ODH was found in 201 (28.4%) eyes, at least one CWS was found in 101 (14.3%) eyes and 88 eyes had both ODH and CWS (12.4%). At presentation, Frisén grade was associated with the presence and severity of ODH and CWS (p<0.001). ODH were associated with a worse visual acuity and CWS were associated with a worse visual field grade and mean deviation at presentation (p<0.05). Frisén grade was associated with worse visual function at presentation and final follow-up (p<0.001). Neither ODH nor CWS at presentation were associated with visual function at final follow-up when controlling for the Frisén grade.Conclusions and relevanceODH and CWS at baseline are not independent predictors of final visual function in IIH when controlling for the severity of papilloedema.
