Efficacy and safety analysis of intravitreal bio-similar products of bevacizumab in patients with macular edema because of retinal diseases.

Purpose: The purpose of this study was to evaluate retrospectively the efficacy and safety profile of intravitreal injection of bevacizumab bio-similar product Zybev(Z) for macular edema because of retinal diseases. Methods: A retrospective analysis was conducted on patients with macular edema because of retinal diseases, who had been administered intravitreal injections of bio-similar bevacizumab at a tertiary eye care center. Changes in the retinal thickness and visual acuity were evaluated to judge the efficacy, and adverse events were noted for the safety profile over a period of 6 weeks. Results: A total of 104 patients were included in the study. The mean age of the patients was 53 ± 13.5 years. The mean pre-injection best corrected visual acuity (BCVA) was 1.32 ± 0.70 log minimum angle of resolution (logMAR) with a central subfield thickness (CST) of 429.26 ± 204.30 µm, and the post-injection BCVA at 6 weeks was 1.13 ± 0.71 logMAR with a CST of 302.26 ± 104.50 µm; this change was statistically significant (P < 0.05) for all groups. The mean average cube thickness (µm) decreased from 11.85 ± 1.96 pre-injection to 10.52 ± 1.75 post-injection, and the mean average cube volume (mm3) decreased from 329.30 ± 54.35 to 302.23 ± 49.56 (P < 0.05). During the follow-up period after injection, no patient had inflammation, endophthalmitis, an increase in intra-ocular pressure, or systemic side effects. Conclusion: This short-term retrospective analysis provides evidence regarding the efficacy and safety of intravitreal injection of bio-similar products of bevacizumab for the treatment of macular edema because of retinal diseases.

Long term outcomes of gastric mucosa-associated lymphoid tissue lymphoma treated with radiotherapy: A multi-center retrospective cohort study.

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease. Radiotherapy remains an important definitive modality. We assessed the long term outcomes of patients with early stage gastric MALT marginal zone lymphoma (MZL) treated with definitive radiotherapy at three institutions in New South Wales, Australia. A retrospective, multi-center study of patients with gastric MALT MZ lymphoma treated with radiotherapy between 1st of March 1999 and 31st of May 2020 was conducted. Eligible patients were: age ≥18 years, treated with curative-intent radiotherapy, pathological diagnosis of MALT MZ lymphoma. There were 33 eligible patients. Complete response (CR) was reported in 30/31 (96.7%) of endoscopically assessed cases. During median follow up of 66.2 months (IQR 22-119 months), estimated 5 and 10 years local relapse free survival were 92.6% (95% CI: 83-100) and 92.6% (95% CI: 83-100); distant relapse free survival 95.8% (95% CI 88.2-100) and 64.7% (95% CI 43.4-96.4); freedom from treatment failure 92.6% (95% CI; 83.1-100) and 62.5% (95% CI; 41.7-93.7), respectively. There were six documented recurrences; one local, four distant, and both in one patient; two cases were high grade recurrences. 5 and 10 years OS were 92.4% and 73.5% respectively. There were no grade 3-5 late toxicities or treatment related deaths. Patients with gastric MALT MZL treated with definitive radiotherapy have excellent outcomes. In long term follow up a significant proportion developed distant low grade disease. Extended follow up should be considered in these patients. Treatment is well tolerated with minimal toxicity. Radiotherapy remains an important modality in the treatment of gastric MALT MZ lymphoma.

Functional Transnasal Endoscopic Conjunctivorhinostomy.

The various surgical options for lacrimal tract reconstruction include canaliculodacryocystorhinostomy; fundal transposition; Conjunctivodacrocystorhinostomy with Jones tube; and in extreme cases conjunctivo-rhinostomy (CR) for total lacrimal bypass. The first three require partial lacrimal tract presence/ integrity while CR is indicated when the canaliculi and/or sac are nonfunctional. This report describes a novel technique of minimally invasive CR through a predominantly endoscopic endonasal approach and further discusses its advantages over other established techniques.

Corneal endothelial changes following cataract surgery in hard nuclear cataract: Randomized trial comparing phacoemulsification to manual small-incision cataract surgery.

Purpose: To evaluate and compare endothelial cell changes in phacoemulsification and manual small-incision cataract surgery (MSICS) in patients with uncomplicated senile cataracts. Methods: This was a prospective: , tertiary care hospital-based, randomized, double-blinded interventional study. In total, 152 patients with an uncomplicated senile cataract of nuclear grade III and above were recruited. Exclusion criteria included patients with preoperative endothelial cell density (ECD) less than 1500 cells/mm3, a history of previous ocular surgery, any other coexisting ocular disease, and intraoperative or postoperative surgical complications. Preoperative and postoperative values of ECD and central corneal thickness (CCT) were measured, analyzed, and correlated with various factors. Results: Patients were randomized into two interventional groups-MSICS and phacoemulsification. Factors associated with significant drop in postoperative ECD following phacoemulsification were patients with advanced age (P = 0.01), higher grades of cataract (P = 0.01), and longer effective phacoemulsification time (P = 0.007). Shallow anterior chamber depth (ACD) was strongly associated with greater ECD loss in both groups (P < 0.0001). A threshold value of 2.86 mm of ACD was defined for minimal endothelial cell loss following phacoemulsification. CCT was observed to slightly increase postoperatively in both groups but was insignificant (P > 0.05). Conclusion: Both MSICS and phacoemulsification have similar postoperative visual outcomes. An increase in postoperative CCT is insignificant following surgery. Greater postoperative ECD loss is associated with phacoemulsification with advanced age, hard nuclear cataracts, and longer effective phacoemulsification time. ACD can be used as an essential parameter preoperatively to determine the choice of surgical technique between MSICS and phacoemulsification.

Clinical epidemiology of gallbladder cancer in North-Central India and association of immunological markers, NLR, MLR and PLR in the diagnostic/prognostic prediction of GBC.

INTRODUCTION: The incidence of Gallbladder Cancer (GBC) is found to be increasing in the rural populations of north-central India. Role of multiple demographic factors, including poor socio-economic conditions, illiteracy and miserable primary healthcare services appear to be significant factors for this increase. Here, we aim to assess the present status of GBC in north-central India and evaluate the role of immunological markers in its management. METHODS: A total of 1845 cases of different Gallbladder diseases, including GBC, from rural and urban areas both, registered at CHRI, Gwalior during 2009-2014 and 2018 were included in this study. The demographic and clinical information of the patients were analysed using various statistical tests. RESULTS: Of all the cases (1845) included in this study, 1125 (60.97%) were diagnosed with GBC, of which, 707 (62.84%) were from rural background and 418 (37.15%) from urban settings. Mean age for GBC cases for both male and female was about 53.49 years. Females were more affected, being 70.37%, while male patients were only 29.63%. The pathological investigations showed elevated levels of total bilirubin and liver function enzymes both. The NLR, PLR and MLR were found to be significantly associated with different clinical parameters as well as OS. CONCLUSION: We infer that the growing trend of GBC, particularly in rural areas, in north-central India is primarily associated with the lack of awareness, inadequate medical support and poor socio-economic conditions. Evaluation of haematological markers may help in the predictive diagnosis/ prognosis and or management of GBC cases in the studied population.

Integrated genomic analysis reveals mutated ELF3 as a potential gallbladder cancer vaccine candidate.

Gallbladder cancer (GBC) is an aggressive gastrointestinal malignancy with no approved targeted therapy. Here, we analyze exomes (n = 160), transcriptomes (n = 115), and low pass whole genomes (n = 146) from 167 gallbladder cancers (GBCs) from patients in Korea, India and Chile. In addition, we also sequence samples from 39 GBC high-risk patients and detect evidence of early cancer-related genomic lesions. Among the several significantly mutated genes not previously linked to GBC are ETS domain genes ELF3 and EHF, CTNNB1, APC, NSD1, KAT8, STK11 and NFE2L2. A majority of ELF3 alterations are frame-shift mutations that result in several cancer-specific neoantigens that activate T-cells indicating that they are cancer vaccine candidates. In addition, we identify recurrent alterations in KEAP1/NFE2L2 and WNT pathway in GBC. Taken together, these define multiple targetable therapeutic interventions opportunities for GBC treatment and management.

Epigenetic downregulation of desmin in gall bladder cancer reveals its potential role in disease progression.

Background & objectives: Gall bladder cancer (GBC) is a fatal neoplasm, with a globally variable incidence rates. To improve the survival rate of patients, a newer set of biomarkers needs to be discovered for its early detection and better prognosis. Our earlier studies on GBC proteomics and whole-genome methylome data revealed expression of desmin to be significantly downregulated with correlated promoter hypermethylation during gall bladder carcinogenesis. Thus, to evaluate desmin as a potential biomarker for GBC, we carried out a detailed follow up study. Methods: Methylation-specific polymerase chain reaction (MS-PCR) (n=17, GBC and n=23, non-tumour control), real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) [n=14, GBC and n=14, adjacent non-tumour (ANT)], immunohistochemistry (n=27, GBC and n=14, non-tumour) and immunoblotting (n=13, GBC and n=13, ANT) were performed in surgically removed gall bladder tissue samples. Results: MS-PCR analysis showed methylation of desmin in 88.23 per cent (15/17) gall bladder tumour samples as compared to non-tumour tissues (39.13%, 9/23). Real-time qRT-PCR analysis revealed a significant downregulation of desmin expression in GBC as compared to ANT tissue. This was further confirmed by western blot, showing reduced expression of desmin protein in GBC, as compared to non-tumour tissue. Immunohistochemical analysis also showed a decreased level of desmin i.e., more than 95 per cent (26/27) in tumour cells compared to non-tumours (35.71%, 5/14). Interpretation & conclusions: The increased frequency of desmin promoter methylation which could be responsible for its significant downregulation, indicates its potential as a candidate biomarker for GBC. This requires further validation in a large group of patients to evaluate its clinical utility.

Comparative clinical trial of intracameral ropivacaine vs. lignocaine in subjects undergoing phacoemulsification under augmented topical anesthesia.

Purpose: To compare intracameral Ropivacaine to Lignocaine during phacoemulsification under augmented topical anesthesia, in terms of efficacy and safety. Methods: This prospective, randomized, double-masked clinical trial included subjects planned for phacoemulsification with posterior chamber intraocular lens implantation for visually significant uncomplicated senile cataract, under augmented topical anesthesia. Cases were randomized into two groups, Group A (Ropivacaine 0.1%) or Group B (Lignocaine 1.0%). The pain experienced by the patients during the surgery, mydriasis, post-op inflammation and endothelial cell change at six weeks after the procedure was evaluated. Surgeon's feedback was recorded to evaluate the cooperation of the patient during surgery. Results: A total of 210 subjects were screened and 184 were randomized to have 92 subjects in each group. There was no statistically significant difference seen on comparing Group A and B with respect to Age (P = 0.05), painful surgical steps (P = 0.85), visual analog scale scores (P = 0.65), surgeon's score (P = 0.11), postoperative inflammation (P = 0.90) and average ultrasound time during phacoemulsification (P = 0.10). Subjects in Group A fared better when compared to Group B with respect to endothelial cell loss (P = 0.0008), and augmentation in mydriasis (P < 0.001). Conclusion: Intracameral Ropivacaine and Lignocaine, both are equally effective in providing analgesia during phacoemulsification. However, intracameral Ropivacaine is superior to Lignocaine with regards to corneal endothelial cell safety, and augmenting mydriasis.

A case of isolated bilateral cataract following high-voltage electrical injury.

High voltage electric burns can cause various ocular injuries and may manifest in the form of conjunctival hyperemia, corneal opacities, uveitis, miosis, spasm of accommodation, cataract, retinal edema, papilledema, choroidal rupture, chorio-retinal necrosis/atrophy, retinal detachment and optic atrophy. The involvement of crystalline lens exclusively with sparing of other ocular structures is rare. We report a case of 16 year old male with bilateral total cataract after electrical injury by over-head high tension electric transmission cable accidentally falling on patient's head 6 months back. B scan showed no abnormality in both the eyes. The intra ocular pressure in both the eyes was within normal limits. Patient underwent lens aspiration with posterior chamber intraocular lens (PCIOL) implantation in both the eyes, under peribulbar anaesthesia (with an interval of 1 week between both the operations). Intra-operative and post-operative period were uneventful. Post operative BCVA was 6/6 in both eyes and fundus examination was within normal limits. Outcomes after surgery are very good if not associated with other ocular lesion like optic atrophy, chorio-retinal lesion, uveitis etc. This observation should encourage the ophthalmologist to undertake surgery for electric cataract, where necessary.

Cortical blindness due to cerebral infarct in advanced pancreatic cancer.

A 65-year-old man, a known case of advanced pancreatic cancer on cisplatin and gemcitabine-based chemotherapy, presented with sudden bilateral painless loss of vision with altered sensorium. Clinical examination showed a normal pupillary light reaction, normal anterior segment and normal fundus. MRI brain showed bilateral parieto-occipital infarct. This report highlights the incidence of cortical blindness due to thromboembolism at the cerebral level in pancreatic cancer. Cerebral ischaemic events occur at an advanced stage of pancreatic cancer already diagnosed at stroke onset and portend a poor prognosis. Anticoagulation therapy, especially low molecular weight heparin, remains the best strategy to prevent recurrences.

Trojan horse anaesthesia: A novel method of anaesthesia for pars plana vitrectomy.

CONTEXT: Topical anesthesia has been used for pars plana vitrectomy (PPV) with limited patient comfort. Thus, augmenting topical anesthesia with intracameral anesthesia (Trojan horse anesthesia) will provide pain-free experience during PPV. AIMS: This study was undertaken to evaluate the patient comfort and surgical safety using 2% lignocaine jelly augmented with intracameral 1.0% lignocaine solution for anesthetizing the eyes undergoing PPV. SETTINGS AND DESIGN: This was a prospective interventional case series at tertiary care hospital. SUBJECTS AND METHODS: Patients planned for PPV for indications other than retinal detachment were included in the study. The pain perception of the participants undergoing PPV under Trojan horse anesthesia was evaluated using visual analog scale (VAS). STATISTICAL ANALYSIS USED: Data analysis was done using descriptive statistics and nonparametric analysis with level of significance at P < 0.05. RESULTS: There were 114 eyes of 114 patients in the study out of which 68.4% (n = 78) were males. The mean age was 42.31 years (range 14-80 years, standard deviation [SD] 18.7). The mean surgical time was 34.0 min (range 13-80 min, SD 14.2). The pain perception on VAS scale averaged 3.0 (range 0-8, SD 1.59, median 3.0). Pain scores were not affected by the age (Pearson correlation = 0.098, P = 0.3), gender (P = 0.44), or the educational status of the participant (P = 0.28). The pain scores were not affected by the indications of surgery (P = 0.58) or the use of silicone oil (P = 0.07). CONCLUSIONS: Trojan horse anesthesia provides adequate analgesia for comfortable and safe 23-gauge PPV with high patient acceptability.

Outcomes and relapse patterns following chemotherapy in advanced Hodgkin lymphoma in the positron emission tomography era.

BACKGROUND: This study evaluated relapse patterns and survival in advanced Hodgkin lymphoma (HL) patients treated with doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) with positron emission tomography (PET) used for staging and response assessment. PATIENTS AND METHODS: Patients aged 18 years or above with newly diagnosed histologically proven Stage III or IV HL treated with ABVD at Calvary Mater Newcastle from January 2005 to December 2012 were included in this study. All patients underwent pre-chemotherapy staging with 18F-fluorodeoxyglucose PET or PET/computed tomography and post-chemotherapy PET or PET/computed tomography for the assessment of response. RESULTS: Forty-three patients were included in the study. The 5-year disease-free survival, progression-free survival and overall survival were 88%, 74% and 86%, respectively. PET complete response was seen in 35 patients (81%), and the 5-year overall survival for this group was 94%. Relapse following a PET complete response was low (three patients) and occurred predominantly at the initial sites of disease. Four of five patients with bulky disease received consolidative radiotherapy and no in-field relapses were observed. CONCLUSION: Advanced stage HL with a PET complete response following ABVD is associated with an excellent prognosis.

Telomere length variation and expression analysis of shelterin complex genes during gallbladder carcinogenesis.

BACKGROUND: Telomeres, which are bound with shelterin protein complex, play an important role in maintaining genomic stability and its dysfunction may lead to carcinogenesis. Here, we aimed to analyze whether shelterin complex gene expression and telomere length variation, play any role in gallbladder carcinogenesis. METHODS: Telomere length analysis was carried out by monochrome multiplex qPCR, whereas expression analysis of shelterin genes was carried out using RT-qPCR. Statistical analysis was carried out using SigmaPlot 11 software. RESULTS: We found significantly reduced telomere length in tumor tissues, and this reduction was seen in both, tumors with or without gallstones in comparison to adjacent non tumor and gallstone (chronic calculous cholecystitis: Inflamed) tissues. Inflamed tissues showed increased telomere length as compared to both adjacent non tumor and tumor tissues. Expression analysis of five shelterin genes showed significant downregulation of TERF1, POT1, and TINF2 genes in inflamed tissues as compared to non tumor and tumor tissues. POT1 was also found to be significantly upregulated in tumor tissues and specifically in tumor tissues with gallstones compared to inflamed tissues. CONCLUSION: This study, thus, suggests that, gallstone does not affect telomere length and even after having increased telomere length, decreased expression of some shelterin genes in inflamed tissue might cause telomeres to cap improperly, possibly leading to telomere dysfunction and further, gallbladder carcinogenesis. Also, increased expression of POT1 in tumor tissues with gallstones could act as a diagnostic marker in patients with gallstones.

Outcome of extraocular retinoblastoma in a resource limited center from low middle income country.

Retinoblastoma (RB) is the most common ocular malignancy in children, and is managed by multimodal treatment. There is a paucity of data regarding the clinical profile and outcome of children with extraocular retinoblastoma from Low Middle Income Countries (LMIC) including India. Case records of children with newly diagnosed extraocular RB from January 2013 to August 2016 treated at our unit were analysed for clinical profile, treatment, and outcome. Over the 44 month study period, 91 children were diagnosed with RB, out of which 41 had extraocular disease. While 26 children had extraocular spread limited to orbit (IRSS stage III), 15 had a distant spread to brain (IRSS stage IV). Median lag period for diagnosis was eight months. Treatment abandonment rates were 38.5% and 46.6% in International Retinoblastoma Staging System (IRSS) stage III and IV respectively. With a median follow up of 31.5 months, the projected overall survival for IRSS III at one, two, and three years was 87.5%, 55.6%, and 39.7%. All patients with stage IV disease died after a median follow up duration of three months. High treatment abandonment rates and limited availability of resources lead to suboptimal survival in children with extraocular RB from LMIC. Initiatives aimed at improving early diagnosis, so that the disease is detected in the intraocular stage, are critical to improve the survival in children with RB.

Thrombolysis for Left-Sided Prosthetic Valve Thrombosis: Short- and Long-Term Outcomes.

BACKGROUND AND AIM OF THE STUDY: Emergency valve replacement has long been the treatment of choice in left-sided prosthetic valve thrombosis (PVT) for critically ill patients in NYHA classes III-IV. Thrombolytic therapy is recommended for NYHA class I/II patients with a small thrombotic burden. METHODS: The results of thrombolytic therapy to treat left-sided PVT (eight mitral, three aortic) with streptokinase (STK) in critically ill NYHA class III/IV patients were analyzed, where surgery was either refused due to financial constraints or by the surgical team. Results were assessed clinically, using fluoroscopy and transthoracic and transesophageal echocardiography. RESULTS: Mechanical bileaflet prosthetic valves (eight mitral, four aortic) were implanted between two and 10 years previously in 11 patients (four females, seven males; age range: 32-54 years). One patient had diabetes and had undergone prior percutaneous coronary intervention with drug-eluting stent implantation to the ostial left main artery. All had cardiomegaly with ejection fraction 24-63% and an increased mean gradient across the immobile prosthetic valve. Patients presented in a hemodynamically unstable state with pulmonary edema and/or hypotensive shock. The International Normalized Ratio was <2.5 in nine patients. Eight patients with mitral valve thrombosis responded to thrombolytic therapy and survived, with complete resolution of thrombus and return of full mobility of leaflets and resolution of valve gradients. To date, all responders have survived (up to five years) without any recurrence of re-thrombosis (PVT). CONCLUSION: Intravenous STK may be life-saving in critically ill NYHA class III/IV patients with left-sided PVT. Thrombolytic therapy is much cheaper and easier to administer than surgical replacement of the thrombosed prosthetic valve.

Very very late stent thrombosis: 9.5 years after DES implantation.

Very late stent thrombosis (VLST) has been recognized as a class effect of 1st generation drug eluting stents (DES) implantation. Although rare, VLST has been reported between 1 and 4 years after DES implantation. Very very late stent thrombosis (VVLST) occurring more than 5 years after DES implantation is extremely rare. We report the first case of a VVLST from India occurring 3465 days (9.5 years) after DES implantation with a brief discussion on its pathogenesis and prevention.

Global methylation profiling to identify epigenetic signature of gallbladder cancer and gallstone disease.

Promoter methylation in various tumor suppressor genes is reported to influence gallbladder carcinogenesis. Here, we aimed to identify methylation status in gallbladder cancer (GBC) by performing a comprehensive genome-wide DNA methylation profiling. The methylation status of 485,577 CpG sites were investigated using Illumina's Infinium Human Methylation 450 BeadChip array in 24 tissues (eight each of tumor, adjacent non-tumor, and gallstone). About 33,443 differentially methylated sites (DMRs) were obtained in the whole human genome, of which 24,188 (72 %) were hypermethylated and 9255 (28 %) were hypomethylated. The data also revealed that majority of the DMRs are localized on the proximal promoter region [Transcription start sites (TSS200, TSS1500) and 5' untranslated region (5'UTR)] and first exon. Exclusion of first exon detected a total of 10,123 (79 %) hypermethylated and 2703 (21 %) hypomethylated sites. Comparative analysis of the later with our differential proteomics data resulted in identification of 7 hypermethylated or down-regulated (e.g., FBN1, LPP, and SOD3) and 61 hypomethylated or up-regulated markers (e.g., HBE1, SNRPF, TPD52) for GBC. These genes could be further validated on the basis of their methylation/expression status in order to identify their utility to be used as biomarker/s for early diagnosis and management of GBC.

Dysfunction of subtelomeric methylation and telomere length in gallstone disease and gallbladder cancer patients of North Central India.

BACKGROUND: Telomeres play an important role in cancer progression. Recently it has been shown that subtelomeric methylation negatively regulates telomere length in various diseases, including cancers. Here, we evaluated the influence of subtelomeric methylation in telomere dysfunction in gallbladder cancer (GBC), and whether this dysfunction is affected by the presence of gallstones. METHODS: Relative telomere length and subtelomeric methylation levels were assessed using monochrome multiplex quantitative polymerase chain reaction and bisulfite sequencing, respectively, in different gallbladder tissue types including different grades of GBC, gallstones and adjacent non-tumor. RESULTS: We found telomere length to shorten significantly in overall GBC, but specifically in early grade cancer. We also found D4Z4 and DNF92 subtelomeric sequences to be hypermethylated and hypomethylated, respectively, in GBC; however, their methylation levels differed significantly, only in early grade cancer. We could not find any specific correlation between subtelomeric methylation and telomere length in GBC. Interestingly, telomere length and subtelomeric methylation differed significantly in GBC without gallstones but not in GBC with gallstones. CONCLUSIONS: This study, thus, suggests that telomere dysfunction and changes in methylation levels may occur earlier in the progression of GBC, while the presence of gallstones may have no influence on telomere length as well as on methylation levels.

Trabeculectomy Under Augmented Topical Anesthesia: Study on Pain Evaluation and Surgical Feasibility.

PURPOSE: Performing trabeculectomy under topical anesthesia using lignocaine jelly with intracameral anesthesia may offer painless surgery with immediate visual gain and avoid the increase in intraocular pressure associated with locally injected anesthesia. In this context, we evaluated topical anesthesia using 2% lignocaine jelly with intracameral 1.0% lignocaine for trabeculectomy in terms of pain during surgery and the surgeon's experience. DESIGN: This was a tertiary care center-based interventional case series. METHODS: Patients scheduled for trabeculectomy as the first surgery for medically controlled glaucoma underwent standard ab externo trabeculectomy under topical anesthesia. Pain evaluation was done using a visual analog scale with the modified Wong-Baker FACES Pain Rating Scale, within 1 hour after surgery. RESULTS: Fifteen eyes of 14 patients were included in the study with a mean (SD, range) age of 61.3 (17.54, 40-90, distributed normally) years. Patients' pain score analysis showed a mean (SD, range) visual analog scale score of 0.73 (0.59, 0-2) on a scale of 0 to 10. The mean (SD, range) surgeon's satisfaction score was 3.2 (0.4, 3-4) on a scale of 3 to 9. The intraocular pressure of all patients was well controlled at 2 weeks [mean (SD, range), 9.2 (2.9, 4-16)] and at 4 weeks [mean (SD, range), 13.2 (1.2, 11-15)] postoperatively without any topical or systemic antiglaucoma medications. CONCLUSIONS: Trabeculectomy can be done under augmented topical anesthesia, which provides adequate analgesia for acceptable patient and surgeon comfort with favorable outcomes. Anesthesia provided by topical application of lignocaine 2% jelly and intracameral 1.0% lignocaine is sufficient for safe trabeculectomy surgery with acceptable discomfort to the patient.

Transscleral fixation of closed loop haptic acrylic posterior chamber intraocular lens in aphakic nonvitrectomized eyes.

PURPOSE: To evaluate the outcome of transscleral fixation of closed loop haptic acrylic posterior chamber intraocular lens (PCIOL) in aphakia in nonvitrectomized eyes. MATERIALS AND METHODS: Patients with postcataract surgery aphakia, trauma with posterior capsule injury, subluxated crystalline lens, and per operative complications where sulcus implantation was not possible were included over a 1-year period. Scleral fixation of acrylic hydrophilic PCIOL was performed according to the described technique, and the patients were evaluated on the day 1, 3, 14, and at 3 and 12 months postoperatively for IOL centration, pseudophakodonesis, change in best-corrected visual acuity (BCVA), and any other complications. RESULTS: Out of twenty-nine eyes of 24 patients, who completed the study, 25 (86.2%) eyes had improved, 2 (6.9%) eyes showed no change, and 2 (6.9%) eyes had worsening of BCVA. Three (10.3%) eyes developed postoperative complications. A significant improvement in mean BCVA (P < 0.0001) was observed after the procedure. Mean duration of follow-up was 26.2 months (range 22-35 months). CONCLUSION: The use of closed loop haptic acrylic IOL for scleral fixation appears to be safe and effective alternative to conventional scleral fixated polymethyl methacrylate intraocular lenses.
