IN the intriguingproblem of thedynamics ofaqueous humour there has recently been a shift in emphasis from what one might call the strictly biochemical approach, to a consideration of the bulk flow of aqueous humour utilizing electronic devices and tracer substances. This study is based on direct observation of the rate of flow of aqueous humour on 88 glaucomatous and normal patients. Since the ...

Uveitis and primary intraocular lymphoma (PIOL) are diseases associated with the invasion of lymphocytes into various regions of the eye, accompanied by expression of inflammatory cytokines. While these diseases are very different in terms of survivability and treatment options they have similar symptoms that make accurate diagnosis challenging. Furthermore, the diagnostic yield with state-of-t...

The structure of the juxtacanalicular meshwork (JCM) was analyzed morphometrically, and the resulting data were used to calculate the resistance to flow through this tissue. Two models of the JCM were presented and compared. In the first (Model A), aqueous humor was assumed to flow via open channels within a solid framework, while, in the second (Model B), these open spaces were assumed to be f...

Endophthalmitis post glaucoma drainage implant (GDI) surgery is rare, often associated with tube or plate exposure. We report a case of endophthalmitis following glaucoma shunt intraluminal stent exposure in a patient who underwent Baerveldt glaucoma implant surgery. Endophthalmitis following manipulation of intraluminal stents is a rare complication of GDIs but potentially vision threatening c...

BACKGROUND Equine recurrent uveitis (ERU) is a common cause of ocular pain and blindness in horses. Leptospira spp. have been commonly implicated in the pathophysiology of ERU in mainland Europe and the USA. No recent studies have been carried out in the UK, but Leptospira is reported not to be a major factor in the aetiology of ERU in the UK. OBJECTIVES To establish the prevalence of Leptosp...

An immunological study of aqueous humour and serum was carried out in experimental ocular candidosis in rabbits. Anti-candida antibody titres, immunoglobulin G, and albumin levels were evaluated in the aqueous humour and in the serum. A local synthesis of anti-candida antibodies was detected in numerous rabbits at the height of clinical activity of the lesions.

Many reports associating uveitis after vaccination have been reported, including 2 cases after measles, mumps, and rubella (MMR) vaccine. We report the case of a 12-month-old girl who developed a unilateral anterior uveitis with rubeosis and cataract 3 months after an MMR vaccination at 9 months of age. Aqueous humor analysis showed the presence of more rubella-specific immunoglobulin G in the ...

Epithelial ingrowth of the bleb cavity, a true Tenon cyst, is a rare complication of a glaucoma drainage implant. Previous cases have been associated with persistent bleb leak, and most have occurred in eyes with prior extraocular surgery. We describe a case of a true Tenon cyst causing strabismus and an elevated intraocular pressure that was successfully treated by surgical revision.

Glaucoma is the leading cause of preventable blindness worldwide. Despite tremendous advances in medical and surgical management of glaucoma in the recent years, the prevalence of glaucoma related blindness is anticipated to increase in the future decades because of the aging population. Stem cells have the potential to change the glaucoma management in several ways. There are several areas of ...

PURPOSE Over the last few years, particular attention has been paid to the implant surface and its influence on the formation and maintenance of surrounding bone. The surface of Osseotite implants (Implant Innovations) is produced by a process of thermal etching, which produces a surface with an average roughness that is twice that of machined implants produced by the same manufacturer. In addi...
