Fornix-based versus limbal-based conjunctival trabeculectomy flaps for glaucoma.

Background: Glaucoma is one of the leading largely preventable causes of blindness in the world. It is usually  addressed first medically with topical intraocular pressure-lowering drops or by laser trabeculoplasty. In cases where such treatment fails, glaucoma-filtering surgery such as trabeculectomy, is commonly considered.

Posterior segment abnormalities in posterior microphthalmos.

Purpose: We report a case of posterior microphthalmos with characteristic papillomacular retinal folds, pigmentary retinopathy, and optic disc drusen.

Observations: A 19-year-old female presented with decreased visual acuity and was found to have bilateral posterior microphthalmos with the presence of papillomacular retinal folds, crowded optic nerves with buried disc drusen, and peripheral retinal pigmentary changes. Optical coherence tomography showed presence of retinal folds involving the inner retinal layers and loss of foveal contour.

An update on postrefractive surgery intraocular pressure determination.

Purpose Of Review: Due to alterations in corneal structure and biomechanics, intraocular pressure (IOP) measurement after refractive surgery has questionable accuracy. Numerous devices and techniques have been evaluated in the past decade. Whereas some methods clearly underestimate postoperative IOPs, other promising leads have emerged that are less affected by laser ablative procedures.

Telerobotic contact transscleral cyclophotocoagulation of the ciliary body with the diode laser.

To assess the feasibility of using the Robotic Slave Micromanipulator Unit (RSMU) to remotely photocoagulate the ciliary body for the treatment of glaucoma with the diode laser. In fresh unoperated enucleated human eyes, the ciliary body was destroyed either with a standard contact transscleral cyclophotocoagulation 'by hand' diode laser technique, or remotely using the RSMU. The treated sections were fixed in formalin, paraffin-embedded, and stained with hematoxylin and eosin.
