PURPOSE To evaluate the changes in anterior chamber depth (ACD) and angle width induced by phacoemulsification and intraocular lens (IOL) implantation in normal eyes using anterior segment optical coherence tomography (AS-OCT). METHODS Forty-five eyes (45 patients) underwent AS-OCT imaging to evaluate anterior chamber configuration before and 2 days after phacoemulsification and IOL implantat...

PURPOSE To study the 24-hour changes in axial length, lens thickness, and anterior chamber depth in rabbits and to examine the role of ocular sympathetic activity on these changes. METHODS Young adult rabbits were entrained to a daily 12-hour light-12-hour dark cycle. Axial length, lens thickness, and anterior chamber depth were measured using ultrasonic techniques. In the first group of 12 r...

BACKGROUND Glaucoma combined with an extremely shallow anterior chamber and cataracts remains as a complex condition to deal with. And the emergence of microincision vitrectomy surgery (MIVS) system may provide an ideal option for the treatment of that. We report a clinical study of surgical outcomes of 23-gauge transconjunctival pars plana vitrectomy (PPV) combined with lensectomy in the treat...

A technique is proposed which allows assessment of the anterior chamber depth with a standard table slit-lamp without any extra attachments. A final approximation is made which suggests that a 1 degree change in the angle between the observation and illumination systems of the slit lamp when the end point is reached indicates a change in anterior chamber depth of 0.1 mm.

Ocular involvement by cysticercosis is uncommon and rare in the anterior chamber. It can give rise to iridocyclitis which can be potentially blinding to the patient. The management is usually surgical. We report a case of 18-year-old girl with large cysticercosis cyst in the anterior chamber. The cyst was removed intact by viscoexpression technique from the anterior chamber of the eye and the p...

Anterior chamber depth was measured in patients with primary open angle glaucoma, low tension glaucoma, pigmentary dispersion syndrome, and glaucoma suspects. Multiple linear regression analysis demonstrated that anterior chamber depth is a function of sex, age, and refractive error. Values for anterior chamber depth corrected for age and refractive error were greater in patients with pigmentar...

PURPOSE This study was designed as a microbiologic survey of the fluids aspirated from the anterior chamber at the end of cataract extraction performed by phacoemulsification, and to correlate the contamination rate of the anterior chamber to the surgical technique used. METHODS One hundred and one consecutive patients (126 eyes) who underwent cataract extraction by phacoemulsification and po...

Shallowness of the anterior chamber received special attention after the demonstration by von Graefe (1857) that iridectomy could cure acute glaucoma. Bowman (I862) referred to the care required in performing iridectomies on eyes with shallow anterior chambers. Over many years, and by careful dissections of cadaver and enucleated eyes, Priestley Smith (I89I) concluded that the shallow anterior ...

Managing iris prolapse After reading the article by Tint et al., we would like to share some comments and tips about dealing with iris prolapse. First, one principle we obey in iris prolapse is to maintain the anterior chamber pressure at a stable and relatively low level. The goal is to prevent recurrent prolapse and minimize damage to the iris, since we found that with each prolapse and repos...
