Perineurioma -a rare cause of proptosis.

Perineurioma is a rare benign soft tissue tumor arising from the peripheral nerve sheath. To date only two cases of orbital perineurioma have been reported in literature. A 45-year-old, with no comorbidities, presented with protrusion of the right eye since one-year. Examination revealed 8mm proptosis of the right eye. Dilated fundoscopy of the right eye showed a pale optic disc with choroidal folds temporal to it. Computerised Tomogram (CT) of the orbit showed a well-defined intraconal mass in the inferotemporal part of the orbit. A trans conjunctival orbitotomy with lateral canthotomy was performed and the tumor was removed en bloc. On immunohistochemistry, the tumour was negative for S-100 and showed patchy weak Epithelial Membrane Antigen positivity which was suggestive of a soft tissue perineurioma.

Kayser-Fleischer-like rings in patients with hepatic disease.

Purpose: The aim of this work was to study Kayser-Fleischer [KF]-like rings in patients with hepatic or cholestatic liver disease and to find out the relation between serum bilirubin level and the presence of KF like ring in these patients. Methods: In this study, we evaluated patients with hepatic and cholestatic liver diseases with total Serum bilirubin levels >10 mg/dl. These patients were evaluated for the presence or absence of KF like ring. Results: A total of 67 patients with total bilirubin >10 mg/dl were included in the study. Patients were divided into 3 groups based on total S. bilirubin level: Group 1 with S. bilirubin >30 mg/dl, Group 2 with S. bilirubin >20 - <30 mg/dl and Group 3 with S. bilirubin >10 - <20 mg/dl at baseline evaluation. On follow-up they were divided into 3 groups based on the serum bilirubin level. Group 1- >20 mg/dl, Group 2- >10 - <20 mg/dl, Group 3- <10 mg/dl. KF like ring was seen in 98.5% of patients with high total S. bilirubin level. KF like ring disappeared in 87.5% of patients with reduction in the total S. bilirubin level to less than 10 mg/dl. Conclusion: KF like ring was seen in 98.5% of patients with high total S. bilirubin, disappeared in 87.5% of patients with reduction in the total S. bilirubin level to less than 10 mg/dl. There was no significant difference between the Total S. bilirubin levels, age, gender and KF Like Ring.

Agreement and repeatability of Icare ic100 tonometer.

PURPOSE: To find the agreement and repeatability of Icare ic100 tonometer. METHODS: We included 150 subjects above the age of 18 years for this cross-sectional, multicenter study with intraocular pressure (IOP) ≥7 mmHg. After the initial ophthalmic examination, two masked examiners took five IOP measurements using three different instruments; Icare ic100, Icare TA01i, and Goldmann applanation tonometer (GAT) in only one eye of the participants. Comparison of agreement of IOP using different instruments was quantified with intraclass correlation coefficient (ICC) using the two-way random effects models of absolute agreement and Cronbach's alpha. The test-retest variability of the instruments was assessed by deriving repeatability coefficient (RC) and coefficient of variation (CV). RESULTS: Agreement between the tonometers across the different IOP groups had no statistically significant difference in their mean IOP. Icare ic100 was found to have good reliability across all IOP groups (ICC value >0.78) when compared with Icare TA01i. In comparison with GAT, Icare ic100 showed good reliability across all IOP groups (ICC >0.87) except >16 to <23 mmHg group where it showed moderate reliability (ICC = 0.52). Icare ic100 showed good repeatability with RC and CV of 2.67 and 4.89, respectively. CONCLUSION: Icare ic100 rebound tonometer can measure IOP with relatively small measurement error and can provide a reliable and repeatable reading in comparison with GAT across a wide pressure range without hampering corneal health.

A comparison of posterior capsular opacification after implantation of three different hydrophobic square edge intraocular lenses.

Purpose: To compare the posterior capsular opacification (PCO) after implantation of three types of hydrophobic square edge intraocular lenses (IOLs). Methods: A single-center, hospital-based, cross-sectional, observational study was conducted wherein patients with senile cataract who had undergone phacoemulsification by a single surgeon, with the implantation of three different types of square edge, hydrophobic IOLs [Group 1: enVista, Bausch and Lomb; Group 2: Tecnis 1 ZCBOO, AMO and Group 3: Acrysof IQ SN60WF, Alcon], and followed up for 12 months were included. The PCO was graded clinically and scored using the EPCO 2000 software. Results: 90 eyes of 90 patients were included. There was no significant difference in the PCO with respect to age, gender, or associated presence of systemic disease. The median PCO score was 0.035, 0.045 and 0.085 in groups 1, 2 and 3, respectively. The PCO grade and score differences between the groups were statistically significant with P < 0.001. Conclusion: The hydrophobic nature and posterior square edge design in the IOLs probably contributed to the minimal visually-significant PCO in all the groups, in our study. However, PCO scores were lesser in the square edge IOLs having a continuous 360 degrees posterior enhanced barrier, than those without this feature.

Isolated neurofibroma of the eyelid mimicking recurrent chalazion.

Neurofibroma is a peripheral nerve sheath tumor which is seen in neurofibromatosis type 1 and is characterized by various ophthalmic manifestations. Solitary neurofibroma of the eyelid is rare. We report a case of a 53-year-old female patient who presented with a painless swelling in the left upper lid of 4 years' duration. She had undergone surgery for the same lesion twice. The lesion was excised and histopathological examination revealed a solitary neurofibroma. She did not have any other features of generalized neurofibromatosis.

Primary squamous cell carcinoma arising from palpebral conjunctiva: A rare presentation.

Squamous cell carcinoma (SCC) of the conjunctiva usually arises from the limbal conjunctiva. Rarely, it can arise from the palpebral conjunctiva. We report a case of primary conjunctival SCC of the palpebral conjunctiva which was treated successfully.

Serum Bile Acids in Patients With Primary Open-angle Glaucoma.

PURPOSE: To measure the serum bile acids (SBA) in patients with primary open-angle glaucoma (POAG) and to compare with nonglaucomatous controls. PATIENTS AND METHODS: A hospital-based case control study of 90 patients above the age of 40 years was conducted. Patients with POAG formed the study group and individuals without glaucoma in the same age group formed the control group. SBA estimation was done using ELISA kit enzymatic assay technique and the median value was compared between the 2 groups. RESULTS: The median of SBA level was found to be more in POAG patients when compared with the control group. The difference was statistically significant (P<0.001). Median SBA level was not affected by the age or sex of the participants in the study. CONCLUSIONS: "Bile acids" may have a role in the oxidative stress and apoptosis involved in the pathophysiology of POAG.

Corneal ulcer due to a rare pleosporalean member of the genus Bipolaris following cow tail injury to the eye: A case report and review of literature.

Aspergillus and Fusarium are the most common fungi causing mycotic keratitis. Injury to the eye with vegetable matter, cow tail injury, long-term use of topical steroids are some of the risk factors for mycotic keratitis. There are few case reports of keratitis caused by Bipolaris. The human pathogenic species in the genus are Bipolaris spicifera, Bipolaris hawaiiensis, Bipolaris papendorfii, and Bipolaris australiensis. Most commonly reported keratitis is caused by B. hawaiiensis, followed by B. spicifera. Literature review showed only one case report of keratitis due to B. australiensis reported from Australia. We present a first case report of keratitis due to B. australiensis (currently Curvularia australienis) from India.

Rare Case of Polymicrobial Keratitis With Balantidium coli.

PURPOSE: To report a rare case of polymicrobial keratitis due to Balantidium coli and gram-negative bacteria, Pseudomonas aeruginosa and Klebsiella pneumoniae, in a soft contact lens (CL) wearer. METHODS: We report a case of CL-related keratitis due to B. coli, P. aeruginosa, and K. pneumoniae. RESULTS: The culture of the corneal scrapings, the CL cleaning solution, and the CL revealed the growth of a rare ciliated parasite, B. coli, along with gram-negative bacteria, namely, P. aeruginosa and K. pneumoniae. The patient was successfully treated with topical broad-spectrum antibiotics and intravenous metronidazole. CONCLUSIONS: Polymicrobial keratitis has seldom been reported with B. coli as the causative agent. CL wear can be a risk factor for this infection. Treatment with topical antibiotics may not suffice, and the intravenous route of antiprotozoal drugs may be a useful adjunct. Increasing awareness, early diagnosis, and treatment may improve the final visual outcome.
