Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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 ± 8.1 years and 62.5 ± 6.9 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 ± 11.97 months) mean period of maintained ambulatory vision than that of group B (26.5 ± 13.5 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.

Abstract
Purpose: To analyze applications for blindness certificates to find causes of visual impairment (VI), handicap, and blindness in a tertiary hospital of Bihar. Methods: Applications for blindness certificates were analyzed over a two-year period. The main cause of blindness, visual handicap, and VI in these applications was ascertained by age group and etiology. VI disability percentages and definitions proposed by Governmen of India (category 0–4; 20–100%) were used to categorize and give percentage to all applicants. Results were compared with data from studies on blindness certificates and population based studies. Results: In total, 203 applicants were reviewed. Mean age was 23.5 ± 7.9 years. Overall, most common cause of visual handicap (40–100% impairment) and blindness (75–100% impairment) was macular pathology (P<.05), while most common cause of overall VI (20–100% impairment) was amblyopia. In age group 0–15 years, most common causes of blindness/visual handicap were congenital globe and hereditary retinal or optic nerve disorders (P = 0.016). In age group 16–30 years, macular pathology was the most common cause of visual handicap [P = 0.007], while amblyopia was the most common cause of VI [P = 0.00]. Between 31 and 45 years of age group, corneal scar in one eye was the most common cause of VI, while macular scar in both eyes was the most common cause of visual handicap. Glaucoma and diabetic retinopathy were the most common causes of blindness/visual handicap between 46 and 65 years and above 65 years of age, respectively. Data about causes of VI such as amblyopia, complicated cataract surgery, and one eyed blindness could not be ascertained by analyzing blindness certificate alone. Conclusion: Data from applications for blindness certificates provide valuable information regarding different causes of VI that might otherwise not be eligible for blindness certification and provide an insight into the overall trends in disease profile and service delivery.

Abstract
Purpose: To study the safety and efficacy of biologic fibrin glue (FG) in comparison with infinity suture in SICS with compromised scleral flap. Methods: A retrospective comparative study of patients who were treated with FG (Group A) with 10–0 nylon (Group B) as sealing agent for intraoperative compromised tunnels in SICS. Parameters noted were postoperative inflammation, wound integrity, anterior chamber (AC) depth, intraocular pressure (IOP), and surgically induced astigmatism (SIA) at postoperative day 1, 4 weeks, 6 weeks, and 6 months, respectively. Epi Info 7 software and SIA calculator, Version 2.1 were used to analyze the result. Results: We reviewed the two groups of 18 patients each and noted that there was no statistically significant difference in postoperative inflammation (P > 0.05), AC depth (P > 0.05), and IOP (P > 0.05) between both groups at each postoperative visit. One patient in Group A showed postoperative shallow AC and subconjunctival bleb. Exposed sutures causing foreign body sensation had to be removed in five patients in Group B. At the end of 6-month postoperative period, no statistically significant difference was found in SIA (P = 0.92) between the two groups. Conclusion: Biologic FG can be safely used in securing the compromised scleral incisions in SICS. It also avoids suture-related complications.

Abstract
Cutaneous horns are uncommon lesions consisting of keratotic material, resembling that of an animal horn. They account for 4% of all eyelid tumors. We report a case of giant cutaneous horn (2 × 1.75 cm) of 4-year duration arising from the right lower lid. Growth excision with direct closure of the defect was done. Histopathological examination revealed it to be well-differentiated squamous cell carcinoma. Most important concern while evaluating cutaneous horns is the underlying condition, which may be benign or malignant. Therefore, histopathological examination is mandatory.

Abstract
INTRODUCTION Hepatitis B Virus (HBV), Hepatitis C Virus (HCV) and Human Immunodeficiency Virus I, II (HIV-I,II) are serious global and public health problem. Knowledge of the seroprevalence would enable early diagnosis, treatment of patients and also help in prevention of horizontal spread of infection by application of universal infection control measures. AIM To determine the seroprevalence of HBV, HCV and HIV I, II infection in patients undergoing ocular surgery. MATERIALS AND METHODS A retrospective review of 560 patients who had undergone ocular surgery between Dec 2014 to June 2015 at Regional Institute of Ophthalmology, Patna, India, was done. Blood samples of patients were tested for the presence of Hepatitis B Surface Antigen (HBsAg) and anti-HCV antibodies by Enzyme Linked Immunosorbent Assay (ELISA) method, while HIV I, II was tested by ELISA and Western Blot as per National AIDS Control Organization (NACO), India guidelines. The number of patients with positive viral serology, age, sex ratio and nature of surgery were analysed. RESULTS Out of 560 patients, 27 (4.8%) patients were found to be positive for viral serology. HBsAg was positive in 22 patients (3.92%). Out of these 14 patients (2.5%) were male while 8(1.4%) were females. Anti- HCV was positive in 3 (0.53%) patients. Out of these 2(.35%) were male and 1 (.17%) was female. HIV was positive in 2 patients (0.35%), both of whom were males. CONCLUSION Keeping in view the number of cases of seropositivity in our study and various studies showing the presence of these viruses in aqueous and tears, we suggest that screening for viral markers should be made mandatory before ocular surgery so that early detection and treatment of patients can be done and risk of horizontal spread is minimized.

Abstract
PURPOSE The aim of this study was to evaluate the efficacy and safety of topical interferon α-2b (IFNα2b) as a single therapy for primary ocular surface squamous neoplasia (OSSN). METHODS Medical records of 24 eyes of 24 patients with primary OSSN were reviewed retrospectively. The diagnosis of OSSN was primarily based on the slit-lamp examination. All cases were treated with topical IFNα2b (1 million IU/mL) 4 times daily. The duration of treatment, tumor response, adverse effects, and number of vials of topical IFNα2b were noted. Complete response was defined as total disappearance of lesions. RESULTS The complete remission of the tumor was observed in 22 patients (91.6%). Two patients (8.3%) did not respond to the treatment. The mean age was 62.44 ± 13.65 years (range, 50-92 years). The mean follow-up period was 18.81 ± 3.81 months (range, 14-22 months). The median greatest linear dimension was 6 mm (range, 5.2-12 mm). In all successful remissions, the median time to lesion resolution was 3.25 months. Adverse effects of topical IFNα2b included spontaneous intratumoral bleeding after 3 weeks of topical therapy in 1 patient. No long-term complication or recurrence was found at the end of the follow-up period. CONCLUSIONS Topical IFNα2b is effective and safe as a single therapy in the management of primary OSSN with minimal self-limited adverse effects. It may provide the least invasive way of treating OSSN.
