PURPOSE: To report the role of CT chest and cytology in suspected tubercular and sarcoid uveitis. METHODS: This is a retrospective, interventional case series of 376 uveitis patients with suspected ocular tuberculosis (TB)/sarcoidosis seen between January 2010 and April 2015 at the Advanced Eye Centre, Post Graduate Institute of Medical Education and Research, Chandigarh. All underwent CT chest, and had following inclusion criteria: (1) Presence of active granulomatous anterior/intermediate/posterior uveitis or panuveitis; (2) a documented tuberculin skin test/QuantiFERON-TB Gold test; (3) all other causes of infectious/non-infectious uveitis ruled out...

BACKGROUND: Tubercular vasculitis is an important manifestation of ocular tuberculosis and this report highlights the mimicking nature of the disease with frosted branch angiitis. RESULTS: A patient presented with a severe form of retinal vasculitis in both eyes and a branch retinal vein occlusion in the left eye. He had a positive tuberculin skin test (TST) and a raised erythrocyte sedimentation rate (ESR) and serum angiotensin-converting enzyme (ACE) levels. Radiological investigations revealed a sub-pleural nodule and mediastinal lymph nodes, which on histopathological evaluation confirmed a granulomatous etiology...

PURPOSE: Pseudomonas aeruginosa is the most common causative organism for contact lens-associated corneal ulcer and is commonly treated with fluoroquinolones. With the emergence of resistant strains, it is important to investigate alternative therapies. Despite well-established efficacy of tazocin against systemic Pseudomonas infections, its topical use for the treatment of Pseudomonas keratitis has not been described, hence this study was aimed to find the ocular permeation of Tazocin and its efficacy in treating keratitis in rabbit eyes...

Semifluorinated alkanes (SFAs) are amphiphilic liquids that can dissolve hydrophobic drugs to form clear solutions. This study evaluated the potential of two SFAs to act as vehicle for topical ocular drug delivery. After confirming ocular safety, an ex vivo corneal penetration model was developed to determine drug distribution and corneal bioavailability. Hydrophobic dye distribution in the different corneal layers was visualised under a confocal microscope. Corneal bioavailability of cyclosporine A (CsA) dissolved in perfluorobutylpentane (F4H5) or perfluorohexyloctane (F6H8) was compared to commercially available CsA ophthalmic emulsions, Restasis® and Ikervis®...

In an effort to find new ocular hypotensive drug candidates, a total of 27 condensed benzimidazoles based compounds were screened. This study was done in normotensive rats and rebound tonometry was used to estimate IOP. All compounds were topically applied as a single drop, unilaterally, at 3 different concentrations (0.1%, 0.2% and 0.4%). The contralateral eye was instilled with vehicle and served as control. The IOP reduction was measured up to 6h. We observed that, with a single topical instillation, four compounds RU 551, RU 555, RU 839 (pyrimido[1,2-a]benzimidazole), and RU 615 (imidazo[1,2-a]benzimidazole) showed significant IOP lowering activities in ocular normotensive rats...

Blunt trauma is the most common cause of posterior dislocation of the crystalline lens. We describe a rare case of subretinal migration of crystalline lens through the giant retinal tear following blunt ocular trauma. This incidental finding of subretinal dislocation of lens following blunt ocular trauma was confirmed on histopathological examination of the enucleated eye. This complication has not been described by histopathological examination in literature so far.

Xeroderma pigmentosum (XP) is an autosomal recessive disorder associated with multiple oculocutaneous manifestations.We discuss a unique case of XP having bilateral ocular surface squamous neoplasia (OSSN) and periocular basal cell carcinoma. In the right eye, a large OSSN mass involving the ocular surface extensively along with intraocular invasion was noted, whereas in the left eye, the tumour mass was involving the limbus, and extending up to three clock hours. Because of extensive disease in the right eye, orbital exenteration was performed, and for the left eye, a wide excision of the mass with triple freeze thaw cryo application to the margins followed by amniotic membrane grafting was done...

Vesicating agent, Sulfur mustard (SM), causes devastating eye injury; however, there are no effective antidotes available. Using nitrogen mustard (NM), a bi-functional analog of SM, we have earlier reported that NM-induced corneal injury in ex vivo rabbit cornea organ culture model parallels corneal injury reported with SM. Using this model, we have demonstrated the therapeutic efficacy of dexamethasone (DEX), doxycycline (DOX) and silibinin (SB) in reversing NM (2h exposure)-induced corneal injuries when added immediately after washing NM...

Importance: Eradication of systemic tuberculosis (TB) has been limited by neglected populations and the HIV pandemic. Whereas ocular TB often presents as uveitis without any prior evidence of systemic TB, the existing uncertainty in the diagnosis of TB uveitis may perpetuate missed opportunities to address systemic TB. Objective: To examine the clinical features of TB uveitis and the associations with response to antitubercular therapy (ATT). Design, Setting, and Participants: This retrospective multinational cohort study included patients from 25 ophthalmology referral centers diagnosed with TB uveitis and treated with ATT from January 1, 2004, through December 31, 2014, with a minimum follow-up of 1 year...

PARTICIPANTS: Patients evaluated for phakic intraocular lens surgery at a tertiary eye care centre. METHODS: Patients with corrected visual acuity > 20/40 and AL > 24.5 mm were included in the study.

Lewisite (LEW), a potent arsenical vesicating chemical warfare agent, poses a continuous risk of accidental exposure in addition to its feared use as a terrorist weapon. Ocular tissue is exquisitely sensitive to LEW and exposure can cause devastating corneal lesions. However, detailed pathogenesis of corneal injury and related mechanisms from LEW exposure that could help identify targeted therapies are not available. Using an established consistent and efficient exposure system, we evaluated the pathophysiology of the corneal injury in New Zealand white rabbits following LEW vapor exposure (at 0...

Ocular chemical burns are an ophthalmic emergency and are responsible for 11.5%-22.1% of ocular injuries. Immediate copious irrigation is universally recommended in acute ocular burns to remove the offending agent and minimize damage. Conventional medical therapy consists of the use of agents that promote epithelialization, minimize inflammation, and prevent cicatricial complications. Biological fluids such as autologous serum, umbilical cord blood serum, platelet-rich plasma, and amniotic membrane suspension are a rich source of growth factors and promote healing when used as adjuncts to conventional therapy...
