Restoring the Ocular Integrity of Perforated Corneal Ulcer Using Living Surgical Donor Tissues Derived From Keratoplasty in the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) caused an unprecedented crisis for corneal surgeons who were forced to strategize for an acute shortage of tissues. Here, we report the initial clinical outcomes of utilizing host corneal buttons derived from optical penetrating keratoplasties of pseudophakic bullous keratoplasty (PBK) patients. Two patients presented to our department with a perforated fungal corneal ulcer in one eye during the COVID-19 pandemic. One eye of each of the patients was operated on with non-vascularized host cut tissues preserved in glycerin. The tissues were secured using 10-0 nylon sutures. Good anatomical integrity was achieved in both eyes. An optical penetrating keratoplasty (PK) was done in both eyes after one year for visual rehabilitation, with a final visual acuity of 20/120 and 20/80, respectively, at six months. In conclusion, therapeutic PK using host tissues obtained from the recipients of optical PK is a safe and effective option to restore ocular integrity during a shortage of fresh or glycerol-preserved corneas. However, optical PK is required for the final visual rehabilitation.

Endoscopic endonasal surgery for prolactinomas: prognostic factors for disease control and management of persistent disease.

Only a limited number of studies have focused on the results of the Endoscopic Endonasal Approach (EEA) for treatment of prolactinomas. We sought to assess the effectiveness of EEA for prolactinoma surgery, identify factors for disease remission, and present our approach for the management of persistent disease. Forty-seven prolactinomas operated over 10 years, with a mean follow-up of 59.9 months, were included. The primary endpoints were early disease remission and remission at last follow-up. Resistance/intolerance to DA were surgical indications in 76.7%. Disease remission was achieved in 80% of microprolactinomas and 100% of microprolactinomas enclosed by the pituitary. Early disease remission was correlated with female gender (p=0.03), lower preoperative PRL levels (p=0.014), microadenoma (p=0.001), lack of radiological hemorrhage (p=0.001), absence of cavernous sinus (CS) invasion (p<0.001), and extent of resection (EOR) (p<0.001). Persistent disease was reported in 48.9% of patients, with 47% of them achieving remission at last follow-up with DA therapy alone. Repeat EEA and/or radiotherapy were utilized in 6 patients, with 66.7% achieving remission. Last follow-up remission was achieved in 76.6%, with symptomatic improvement in 95.8%. Factors predicting last follow-up remission were no previous operation (p=0.001), absence of CS invasion (p=0.01), and EOR (p<0.001). Surgery is effective for disease control in microprolactinomas. In giant and invasive tumors, it may significantly reduce the tumor volume. A multidisciplinary approach may lead to long-term disease control in three-quarters of patients, with symptomatic improvement in an even greater proportion.

OPTIC DISK PIT STUFFING-TO DO OR NOT TO DO.

PURPOSE: Optic disk pit (ODP) is a subset of spectrum of congenital cavitary anomalies. Optic disk pit maculopathy causes progressive visual deterioration and is addressed with pars plana vitrectomy (PPV) with or without ODP stuffing. PATIENT AND METHODS: We report a case of progressive ODP maculopathy who was taken up for 23-G 3-port PPV, with complete vitreous removal and stuffing of the ODP with autologous sclera and sequential analysis of change in the retinal nerve fiber layer (RNFL) thickness. RESULTS: Spectral-domain optical coherence tomography RNFL analysis at 1 and 12 months follow-up postoperatively showed total RNFL thickness decrease from 130 µm to 103 µm respectively. Hemiquadrant analysis showed slight reduction of superior RNFL thickness from 142 µm to 139 µm. However, in the inferior hemiquadrant, the reduction in mean RNFL thickness seems to be significant from 133 µm to 100 µm at 1 and 12 months respectively. Sector-wise analysis of the RNFL thickness showed maximum reduction in the inferotemporal quadrant and other sectors seemed to be relatively preserved corresponding to the area of scleral stuffing. CONCLUSION: Retrospective or prospective analysis of RNFL health of patients undergoing surgery for ODP-M with stuffing needs to evaluated.

Epidemiological and microbiological profiles of microbial keratitis in a tertiary eye center in Eastern India (Bihar).

Purpose: To determine the demography, risk factors, and causative organisms of microbial keratitis (MK) in Bihar, an eastern state of India. Design: Retrospective study. Methods: We reviewed the demographic, clinical, and microbiological data of 2303 patients with MK (non-viral) presenting between January 2019 and December 2022. Results: This study revealed a predominance of males (65.0%) compared to females (34.9%), with a mean age of 48.4 ± 16.5 years. The majority of patients (63.1%) presented after 2 weeks from the onset of symptoms. The most common risk factor observed was corneal injury (58.1%), followed by ocular surface diseases (13.6%) and diabetes mellitus (13.3%). The majority of patients (73.16%) were involved in agriculture. Prior to presentation, almost all patients (92%) had received topical antibiotics. Unsupervised use of topical corticosteroids was observed in 29.2% of the patients for the median duration of 3 days (odds ratio, 0.17). At presentation, the median size of corneal ulcers was 5 mm, the best-corrected visual acuity was less than 20/400 in 51.4% of patients, and corneal perforation was in 14% of patients. The smear and culture positivity rate were 75.4% and 47.9%, respectively. The common causative organism was fungus (48.8%), followed by bacteria (17.4%). Aspergillus spp. and Staphylococcus spp. were the most commonly identified organisms; a quarter of the patients (24.5%) remained unidentified. All bacteria showed good sensitivity to vancomycin. Conclusion: MK is a significant cause of ocular morbidity in Bihar. The knowledge of epidemiology, risk factors, and microbiological profiles of MK can provide a valuable approach to disease prevention, diagnosis, and management.

Anatomical and surgical characteristics correlate with pachymeningeal failure in patients with brain metastases after neurosurgical resection and adjuvant stereotactic radiosurgery.

PURPOSE: Neurosurgery (NS) is an essential modality for large brain metastases (BM). Postoperative stereotactic radiosurgery (SRS) is the standard of care adjuvant treatment. Pachymeningeal failure (PMF) is a newly described entity, distinct from classical leptomeningeal failure (LMF), that is uniquely observed in postoperative patients treated with adjuvant SRS. We sought to identify risk factors for PMF in patients treated with NS + SRS. METHODS: From a prospective registry (2009 to 2021), we identified all patients treated with NS + SRS. Clinical, imaging, pathological, and treatment factors were analyzed. PMF incidence was evaluated using a competing risks model. RESULTS: 144 Patients were identified. The median age was 62 (23-90). PMF occurred in 21.5% (31/144). Female gender [Hazard Ratio (HR) 2.65, p = 0.013], higher Graded Prognostic Assessment (GPA) index (HR 2.4, p < 0.001), absence of prior radiation therapy (HR N/A, p = 0.018), controlled extracranial disease (CED) (HR 3.46, p = 0.0038), and pia/dura contact (PDC) (HR 3.30, p = 0.0053) were associated with increased risk for PMF on univariate analysis. In patients with PDC, wider target volumes correlated with reduced risk of PMF. Multivariate analysis indicated PDC (HR 3.51, p = 0.0053), piecemeal resection (HR 2.38, p = 0.027), and CED (HR 3.97, p = 0.0016) independently correlated with PMF risk. PMF correlated with reduced OS (HR 2.90, p < 0.001) at a lower rate compared to LMF (HR 10.15, p < 0.001). CONCLUSION: PMF correlates with tumor PDC and piecemeal resection in patients treated with NS + SRS. For unclear reasons, it is also associated with CED. In tumors with PDC, wider dural radiotherapy coverage was associated with a lower risk of PMF.

LITTing up Gliomas-Is the Future Bright?

Background: Laser interstitial thermal therapy (LITT) represents an attractive therapeutic strategy for several intracranial pathologies; however, there is a paucity of literature regarding its efficacy for the treatment of gliomas. Methods: MEDLINE, EMBASE, Scopus, and Web of Science were searched from inception until March 19, 2021. Studies specifically relating to the use of LITT in treatment of glioma were eligible for inclusion. A meta-analysis of means was performed to assess the progression-free survival (PFS) and overall survival (OS) following LITT and descriptive statistics relating to patients undergoing LITT were collated and a meta-analysis of proportions was also performed to assess the rate of complications. Results: In total, 17 studies were included for the meta-analysis, comprising 401 patients with 408 gliomas of which 88 of 306 (28.8%) were grade 1 or 2 and 218 of 306 (71.2%) were grade 3 or 4. Of these, 256 of 408 (62.8%) were primary presentation and 152 of 408 (37.2%) were recurrent. The pooled mean OS was 13.58 months (95% confidence interval [CI] 9.77-17.39) and the PFS was 4.96 months (95% CI 4.19-5.72). The OS and PFS of recurrent glioblastoma were 12.4 months (95% CI 9.61-16.18) and 4.84 months (95% CI 0.23-9.45), respectively. Complications occurred in 114 of 411 (24%; 95% CI 14-41), of which 44 (11%) were transient deficits. Conclusions: There is an increasing body of evidence demonstrating the use of LITT in the surgical management of deep-seated gliomas in patients of poor performance status. However, further studies are required to interrogate the clinical effectiveness of LITT in the setting of gliomas as well as assessing the survival benefit versus standard treatment alone.

Clinical outcome and course of Tenon's patch graft in corneal perforation and descemetocele.

Purpose: To assess the efficacy and clinical outcome of Tenon's patch graft (TPG) in corneal perforation and descemetocele. Methods: In this retrospective study, medical records of 83 patients (85 eyes) who underwent TPG for corneal perforation (58, 68%) or descemetocele (27, 32%) between July 2018 and October 2021 were reviewed. Clinical examination and anterior segment optical coherence tomography (AS-OCT) were performed on every follow-up visit. Anatomical success was considered as the restoration of the structural integrity with the formation of scar and anterior chamber (AC). Results: The mean size of the corneal lesions (corneal perforation or descemetocele) was 4.20 ± 1.01 mm. The mean follow-up period was 9.2 ± 5.48 months. The common underlying etiologies were infectious keratitis in 48% and autoimmune disorders in 35% of cases. TPG successfully restored the globe integrity in 74 (87%) eyes (83% in perforation and 96% in descemetocele). Anatomical failure occurred in 11 eyes (13%). The failures were due to graft dehiscence (8 eyes), graft ectasia (1 eye), and scarring with flat AC (2 eyes). The median time to epithelialization and scar formation were 3 and 15 weeks, respectively. Logistic regression analysis showed few predictors for a successful outcome: descemetoceles, noninfective causes, viral keratitis in infectious etiology, and paracentral or peripheral lesions. Conclusion: TPG can be considered an effective and inexpensive treatment for restoring the structural integrity in the eyes with perforations and descemetoceles, particularly when the donor tissue is unavailable. AS-OCT is a valuable noninvasive tool for monitoring the graft status.

Endoscopic Treatment of Rathke's Cleft Cysts: The Case for Simple Fenestration.

BACKGROUND: Rathke's cleft cysts (RCC) arise from the pars intermedia because of incomplete regression of the embryologic Rathke pouch. A subset of RCC becomes symptomatic causing headaches, visual and endocrinological disturbances such that surgical intervention is indicated. Several points in surgical management remain controversial including operative strategy (simple fenestration (SF) vs complete cyst wall resection (CWR)) as well as reconstructive techniques. METHODS: A retrospective analysis was conducted of pathologically confirmed RCC operated on by endoscopic endonasal approach from 2006 to 2019. Pre-operative symptoms, imaging characteristics, operative strategy, symptom response, complications and recurrences were recorded. RESULTS: Thirty-nine patients were identified. Thirty-three underwent SF and six underwent CWR. Worsening pituitary function was significantly increased with CWR (50%) compared to SF (3%) (p = 0.008). All patients underwent "closed" reconstruction with a post-operative CSF leak rate of 5% (3% SF vs 16% CWR, p = 0.287). Six (15%) recurrences necessitating surgery were reported. Recurrence rates stratified by surgical technique (18% SF vs 0% CWR, p = 0.564) were not found to be significantly different. CONCLUSIONS: The current series illustrates variability in the surgical management of RCCs. SF with closed reconstruction is a reasonable operative strategy for most symptomatic RCCs cases while CWR can be reserved for selected cases.

Adult isocitrate dehydrogenase-mutant brainstem glioma: illustrative case.

BACKGROUND: Adult brainstem gliomas are rare entities that demonstrate heterogeneous biology and appear to be distinct from both their pediatric counterparts and adult supratentorial gliomas. Although the role of histone 3 mutations is being increasingly understood in this disease, the effect of isocitrate dehydrogenase (IDH) mutations remains unclear, largely because of limited data. OBSERVATIONS: The authors present the case of a 29-year-old male with an IDH1-mutant, World Health Organization grade III anaplastic astrocytoma in the dorsal medulla, and they provide a review of the available literature on adult IDH-mutant brainstem glioma. The authors have amassed a cohort of 15 such patients, 7 of whom have survival data available. Median survival is 56 months in this small cohort, which is similar to that for IDH wild-type adult brainstem gliomas. LESSONS: The authors' work reenforces previous literature suggesting that the role of IDH mutation in glioma differs between brainstem and supratentorial lesions. Therefore, the authors advocate that adult brainstem gliomas be studied in terms of major molecular subgroups (including IDH mutant) because these gliomas may exhibit fundamental differences from each other, from pediatric brainstem gliomas, and from adult supratentorial gliomas.

Arrugas Bone Trephine Assisted Flapless Dacryocystorhinostomy with Circumosteal - Mitomycin C Versus External Dacryocystorhinostomy: A Hospital Based Comparative Study.

INTRODUCTION: Primary acquired nasolacrimal duct obstruction is a common ophthalmic condition and has conventionally been managed by external dacryocystorhinostomy. However this procedure is time consuming and involves making mucosal flaps. The aim of this study was to compare the surgical outcome in Arrugas bone trephine-assisted flapless dacryocystorhinostomy with Circumosteal - Mitomycin C versus conventional external dacryocystorhinostomy. MATERIALS AND METHODS: This is a retrospective non-randomized study of surgical outcome in patients of primary acquired nasolacrimal duct obstruction who underwent an Arrugas bone trephine assisted flapless dacryocystorhinostomy with Circumosteal - Mitomycin C (group A) versus those who underwent conventional external dacryocystorhinostomy (group B) in a teaching hospital in North India. Patients with previously failed dacryocystorhinostomy, lacrimal fistula, canalicular and common canalicular obstruction were excluded. Success was defined as patent syringing at the end of one year. Surgical time was calculated from skin incision to skin suturing. RESULTS: There was complete resolution of epiphora with patent syringing in 43 out of 52 patients in group A, while in group B, 47 out of 55 patients had complete resolution of epiphora with patent syringing at the end of one year (p= 0.77). Mean surgical time was significantly lower in Group A than in Group B (p=<.05). Scarring and closure of the ostium was the most common cause of failure in both groups (Group A, n=5, 9.6%; Group B, n= 3, 5.45%). CONCLUSION: Arrugas bone trephine-assisted flapless dacryocystorhinostomy with Circumosteal - Mitomycin C is a viable alternative to conventional external dacryocystorhinostomy with comparable success rate and shorter surgical time and a faster learning curve.

Keratitis occurring in patients treated with miltefosine for post-kala-azar dermal leishmaniasis.

AIM: To describe the characteristic clinical features and management of keratitis in the patients receiving miltefosine for post-kala-azar dermal leishmaniasis (PKDL). METHODS: The medical records of five patients with PKDL who presented with keratitis were reviewed retrospectively from April 2018 to December 2019. The evaluation included a thorough medical history including details on drugs used, particularly miltefosine. The drug causality assessment was also performed. The clinical and microbiological characteristics of keratitis were noted. RESULTS: The ocular symptoms included pain, redness, watering, photophobia and diminution of vision. Slit-lamp biomicroscopy revealed peripheral, paralimbal, ring-shaped, full-thickness stromal infiltration resulting in ulcerative keratitis in all cases. Two patients had unilateral keratitis, while three had bilateral keratitis. All five patients received miltefosine for an average period of 48 days before the onset of keratitis. The corrected distance visual acuity at presentation ranged from hand movement to 20/125. The causality assessment revealed a 'probable' association between the adverse drug reaction and miltefosine in all patients. Discontinuation of miltefosine and initiation of corticosteroid therapy resulted in resolution of keratitis in all cases. The unilateral keratitis treated with topical corticosteroids had improved outcomes, but poor outcomes were found in the bilateral keratitis. CONCLUSION: These observations indicate that prolonged use of miltefosine might cause keratitis that resembles infectious keratitis. Early diagnosis with discontinuation of the drug and initiation of corticosteroid therapy are the key to successful management.

Brain Metastases: A Modern Multidisciplinary Approach.

Brain metastases (BM) are the most common intracranial neoplasm and represent a major clinical challenge across many medical disciplines. The incidence of BM is increasing, largely due to improvements in primary disease therapeutics conferring greater systemic control, and advancements in neuroimaging techniques and availability leading to earlier diagnosis. In recent years, the landscape of BM treatment has changed significantly with the advent of personalized targeted chemotherapies and immunotherapy, the adoption of focal radiotherapy (RT) for higher intracranial disease burden, and the implementation of new surgical strategies. The increasing permutations of options available for the treatment of patients diagnosed with BM necessitate coordinated care by a multidisciplinary team. This review discusses the current treatment regimens for BM as well as examines the salient features of a modern multidisciplinary approach.

Current Results of Surgical Treatment of Craniopharyngiomas: The Impact of Endoscopic Endonasal Approaches.

Surgery is the main treatment option for the management of craniopharyngiomas. Transcranial microsurgical approaches, such as pterional and subfrontal approaches, have constituted the classic operative strategy for resection of these tumors. However, the development of endoscopic endonasal approaches has revolutionized the treatment of craniopharyngiomas in the last 15 years, and endoscopic resection is favored for most craniopharyngiomas. In this article, we discuss our experience with the management of craniopharyngiomas and review the current results of the surgical treatment of those tumors, including discussion of goals of surgery, complications, recurrences, and the role of adjuvant treatment.

Slit-beam retro-illumination assisted phacoemulsification for cataract with coexisting corneal opacity.

INTRODUCTION: We describe a novel surgical technique of slit-beam retro-illumination assisted phacoemulsification for cataract with coexisting corneal opacity. CASES: We present two cases with cataract and coexisting opacity, who underwent slitbeam retro-illumination assisted phacoemulsification and further application of same process in 12 patients. CONCLUSION: This technique is safe and provides excellent visualization during cataract surgery in patients with corneal opacities.

The Importance of Long Term Follow Up After Endoscopic Pituitary Surgery: Durability of Results and Tumor Recurrence.

INTRODUCTION: Endoscopic endonasal approach (EEA) has become the preferred surgical approach for resection of pituitary adenomas in most centers. This technique has a number of advantages such as improved visualization and maneuverability, when compared to microscopic transsphenoidal approach. However, the long-term results of this approach are still scarce. Ten years ago, we published our initial series of patients having undergone an endoscopic removal of their pituitary adenomas reporting favorable short-term results. This project aims to revisit the results of that series, addressing the long-term results regarding recurrence of pituitary adenomas. METHODS: A retrospective analysis of consecutive, endoscopically managed pituitary adenomas in a single center from 2004-2007. Only patients with >5 years of follow up (FU) and complete follow up data were included in this study. Recurrences were defined as evidence of any new tumor growth or enlargement of previously noted residual adenoma and/or biochemical recurrence of disease activity, in cases of functioning adenomas. RESULTS: A total of 98 patients matched the inclusion criteria for this study. The median follow-up period was 144 months. Nonfunctioning adenoma was the most common subtype (n = 66, 67.3%), followed by GH-secreting tumors (n = 19, 19.4%), ACTH-secreting tumors (n = 7, 7.1%), prolactinomas (n = 4, 4.1%) and TSH-secreting adenomas (n = 2, 2%). Age ranges from 23 to 82 years, with median age of 53 years. Preoperative visual deficits were observed in 46 patients (46.9%) and hormonal deficits were identified in 31% of cases. 22.4% of patients had undergone a previous pituitary adenomas resection prior to treatment in our center. Surgery achieved gross total resection (GTR) and near total resection (NTR) in 89 cases (90.8%) (56.1% and 34.7%, respectively). A total of 37 cases had recurrences during FU (mean recurrence free survival: 80 months). Recurrences were observed in 34% of patients who had had GTR while recurrences were observed in 39.5% of cases that underwent subtotal resection. Most recurrences occurred after 5 years of FU and univariate analysis demonstrated previous surgery (P = 0.005), cavernous sinus invasion (P = 0.05) and Ki-67 >5% (P = 0.01) to be factors associated with higher chance of recurrence. Multivariate Cox-regression analysis demonstrate that previous surgery and Ki-67 >5% are factors associated with recurrences. Surgery and/or radiation were utilized for management of recurrences in 29/37 cases. CONCLUSION: Long-term FU analysis demonstrates that progression/recurrence of previously resected adenomas is observed in a significant number of patients, especially in those with previous/multiple surgical resections, elevated ki-67 and cavernous sinus invasion. Short-term FU may shadow real tumor control rates achieved after EEA and underscores the importance of long-term FU in these patients. Therefore, long-term FU should be pursued in all cases.

Expanded Endoscopic Endonasal Approach for Removal of a Tuberculum Sella Meningioma.

This 46-year-old female patient presented after a 6-month progressive right-sided visual loss, with a visual acuity of 20/60, a temporo/infranasal visual field deficit, and optic atrophy. The magnetic resonance imaging disclosed a tuberculum sella meningioma with minimal right medial canal invasion, however, no encasement of carotid arteries. Tuberculum sella meningiomas represent 5%-10% of intracranial meningiomas and are surgically challenging tumors that can severely hinder vision. The endoscopic approach allows for early coagulation of the tumor meningeal supply, and importantly, facilitates gross total removal without any manipulation of the optic nerve while preserving the superior hypophyseal arteries.1-9.

Pediatric Neurosurgery in East Africa: An Education and Needs-Based Survey.

INTRODUCTION: A pediatric neurosurgery training workshop was organized for residents and consultants in East Africa. We aimed to compile feedback from the course participants to 1) characterize the state of neurosurgical education; and 2) identify the perceived practical education needs. METHODS: The survey of demographic, clinical background and practice, and feedback questions was distributed to all attendees. Responses were elicited via yes/no questions and Likert scales, with the score ranging from 1 (not important, not useful, never) to 5 (very important, very useful, often). The data were de-identified and analyzed in aggregate. RESULTS: A total of 11 neurosurgeons and trainees completed the survey, including 6 residents (55%) and 5 consultants (45%). Although 5 countries of origin were represented, all attendees (100%) have completed their neurosurgery training in Kenya. The respondents had most frequently treated trauma (least common to most common, 1-5; mean, 4.55 ± 0.93), hemorrhagic stroke (mean, 4.27 ± 0.79), and pediatric tumors (mean, 4.27 ± 1.01). In training, the most commonly used study resources were online resources (9; 82%), textbooks (7; 64%), and online lectures (7; 64%). The areas of greatest perceived need in education and training included general neurosurgery (least to most need, 1-10: 9; 82%), pediatric (9; 82%), trauma and neurocritical care (7; 64%), and neuro-oncology (7; 64%). All 11 respondents (100%) reported that more direct operative teaching was important for educational improvement. Hydrocephalus (least to most useful, 1-5: 5.00 ± 0.00), neuro-endoscopy (4.91 ± 0.30), and tumor (4.91 ± 0.30) were considered the most useful content covered in the pediatric neurosurgery-focused training program to improve skills and knowledge base. CONCLUSIONS: The results from the present survey identified areas of education and training needs to guide further neurosurgical education efforts in East Africa.

Long-Term Visual Outcome in Surgical Management of Cataract Coexistent With Corneal Opacity in One-Eyed Patients.

PURPOSE: To determine the visual outcome and safety of cataract surgery alone and compare with the long-term visual outcome of triple procedure in one-eyed patients. DESIGN: Retrospective study. METHODS: This study reviewed 44 one-eyed patients with cataract coexistent with corneal opacity. The patients who underwent cataract surgery alone (group A, n = 25) were compared with patients managed by triple procedure (group B, n = 19). Outcome measures were the improvement of best corrected visual acuity (BCVA) and period of maintained ambulatory vision. Institutional ethics committee approval was obtained. RESULTS: The most common etiology of corneal opacity was fungal and the commonest cause of permanent visual loss in other eye was phthisis bulbi. Mean age was 61.2 ±â€Š8.1 years and 62.5 ±â€Š6.9 years in groups A and B, respectively. At each follow-up, the mean postoperative BCVA was found significantly better than the preoperative vision in both groups and at the end of 3 years, mean postoperative vision of group A was better than that of group B (P = 0.012). Group A had longer (33.36 ±â€Š11.97 months) mean period of maintained ambulatory vision than that of group B (26.5 ±â€Š13.5 months) (P = 0.245) and showed less risk of losing ambulatory vision. Limited visual outcome was due to continuing presence of corneal opacity in group A, and graft infection and graft rejection in group B. CONCLUSIONS: Cataract surgery with intraocular lens (IOL) implantation alone can be considered as an alternative or temporary option to provide stable ambulatory vision in one-eyed patients.

Tacrolimus versus Cyclosporine- Comparative Evaluation as First line drug in Vernal keratoconjuctivitis.

INTRODUCTION: The aim of the study was to evaluate and compare the efficacy, side effects and recurrence rate of vernal kerato conjunctivitis (VKC) with 0.03% tacrolimus and 0.05% cyclosporin. MATERIAL AND METHOD: A prospective randomised double blinded comparative study was conducted at a tertiary eye center. 46 Patients of VKC between March 2015- August 2015 were randomly divided into two groups and treated for 6weeks with either Tacrolimus(0.03%) eye ointment BD or Cyclosporine (0.05%) eyedrops QID.The main outcome measures were scoring and comparison of Total subjective symptom scores (TSSS) and Total objective ocular sign scores (TOSS) within and between the Groups at each follow up.Thirty two patients, sixteen from each group, with comparable baseline characters were analysed. RESULTS: With treatment both TSSS and TOSS decreased consistently in both groups without any adverse effects but an increase in scores was noticed within two weeks after drug withdrawal. CONCLUSION: Both drugs are equally effective and safe in VKC but with short lasting effect.

Posttraumatic Charcot (Neuropathic) Spinal Arthropathy at the Cervicothoracic Junction.

BACKGROUND: Charcot spine arthropathy (posttraumatic neuroarthropathy of the spine) has been reported to be a very late and rare complication of spinal cord injury. Charcot of the cervicothoracic and upper thoracic region rarely is reported in the literature. Charcot spinal arthropathy is a cause of progressive deformity and may present as late as 30 years after the original spinal cord injury. This is more common in paraplegic patients who are actively ambulating. CASE DESCRIPTION: A 56-year-old patient with complete paraplegia for approximately 20 years after spinal cord injury presented with severe kyphous deformity and instability of thoracolumbar spine. His sensory level to deep pain was at thoracic (D4). He kept developing new neuroarthropathies at different segments within a span of 5-6 months after every decompression and fusion with anterior cage and posterior instrumentation done. A total of 3 surgeries had been done in span of 2 years, initially thoracic, then lumbar and finally cervicothoracic junction. CONCLUSIONS: We present this case because of the challenges in surgery for instrumentation of new Charcot spinal arthropathy. Reports of neuroarthropathy developing above the level of spinal cord injury and at the cervicothoracic junction are rare. The treating surgeon should be cognizant of the possibility of developing secondary levels of neuroarthropathy above and below a previously successful fusion.
