Retinal nerve fiber layer thickness evaluation after trypan blue-assisted macular surgery.

Purpose: The purpose of this study was to evaluate retinal nerve fiber layer (RNFL) thickness changes in eyes undergoing trypan blue-assisted macular surgery using optical coherence tomography-3. This is a prospective noncomparative, interventional, and observational case series of 35 eyes of 35 consecutive patients (15 eyes with macular hole, 14 eyes with idiopathic macular pucker, and 6 eyes with tractional diabetic macular edema) who underwent pars plana vitrectomy and peeling of the epiretinal membrane and/or internal limiting membrane assisted with 0.1 mL of 0.

Lamellar macular holes: tomographic features and surgical outcome.

Purpose: To categorize tomographically the distinct entity of lamellar macular holes (MH) and present the surgical outcomes in our patient cohort.

Design: Prospective observational and interventional study.

Methods: All cases were clinically diagnosed initially with slit-lamp biomicroscopy and confirmed with the use of optical coherence tomography (OCT)-3.

OCT-3 study of serous retinal detachment in a preeclamptic patient.

We report optical coherence tomography-3 (OCT-3) of retinal disorders in acute preeclampsia. A 33-year-old woman developed mind hypertension (170/90 mm Hg) and proteinuria in the 28th week of pregnancy. The patient complained of sudden and severe visual acuity decrease.

Retinal astrocytic hamartoma with associated macular edema: report of spontaneous resolution of macular edema as a result of increasing hamartoma calcification.

The purpose of this article is to report a case of retinal astrocytic hamartoma with an associated macular edema and the spontaneous resolution of the latter due to an increase in hamartoma calcification over a seven-year follow-up period. Clinical examination, red-free and colour fundus photographs, fluorescein angiography, and optical coherence tomography were performed during a seven-year follow-up. We conclude that retinal astrocytic hamartomas may be associated with cystoid macular edema.

Primary pars plana vitrectomy versus scleral buckle surgery for the treatment of pseudophakic retinal detachment: a randomized clinical trial.

Objective: To compare the anatomical and functional outcome of scleral buckle (SB) surgery with that of pars plana vitrectomy (PPV) alone in the treatment of primary rhegmatogenous pseudophakic retinal detachment (RD).

Methods: In this prospective, randomized clinical trial, 150 eyes of 150 patients with pseudophakic RD and proliferative vitreoretinopathy (PVR) stage B or less were randomized to SB surgery (75 eyes) or primary PPV (75 eyes). SB surgery involved break localization, cryotherapy, placement of a circumferential 240 style 2.

Non-contact holmium:YAG laser thermal keratoplasty for hyperopia: two-year follow-up.

Purpose: We evaluated the safety and efficacy of the non-contact holmium:YAG laser thermal keratoplasty (LTK) for the treatment of mild to moderate hyperopia without astigmatism.

Methods: A prospective, non-comparative case series included 50 eyes of 28 patients (aged > or =40 years) who had stable refraction and an astigmatic component < +0.50 diopters (D).

Retinal complications of phakic intraocular lenses.

High myopia has always been a challenge for refractive correction. Current laser surgical techniques, however, fall short of correcting high refractive errors due to lack of predictability, regression, corneal ectasia, and introduction of high order optical aberration. Phakic intraocular lenses (IOL) have been proposed as an effective refractive surgical procedure for the correction of severe myopia, but, despite recent advances in implant material technology and design, their concept is still under clinical investigation.

Functional and anatomic results of macular hole surgery complicated by massive indocyanine green subretinal migration.

Purpose: To report the functional and anatomic results of macular hole (MH) surgery complicated by massive subretinal migration of indocyanine green (ICG) dye.

Design: Interventional case report.

Methods: We performed standard pars plana vitrectomy surgery for a stage 3, senile idiopathic MH.

Posterior capsule rupture and vitreous loss during phacoemulsification with or without the use of an anterior chamber maintainer.

Purpose: To compare the incidence of posterior capsule rupture and vitreous loss during phacoemulsification with and without the use of an anterior chamber maintainer (ACM) SETTING: Aristotle University Eye Clinic, Thessaloniki, Greece.

Methods: The surgical records of patients who had phacoemulsification by experienced surgeons over a 2-year period were reviewed. The cases were divided into 2 groups: surgery performed without the use of an ACM (no-ACM group) and surgery performed with the use of an ACM (ACM group).

Perfluorocarbon liquid utilization in primary vitrectomy repair of retinal detachment with multiple breaks.

Purpose: To evaluate the efficacy of pars plana vitrectomy in conjunction with intraoperative perfluoro-n-octane (PFO) use as initial treatment of retinal detachment (RD) with multiple breaks located at various distances from the ora serrata.

Methods: Twenty-two consecutive eyes (15 phakic, 2 aphakic, and 5 pseudophakic) presenting with RD with multiple breaks and tears underwent primary pars plana vitrectomy, PFO retinal reattachment, transcleral cryopexy or endolaser treatment of breaks, PFO/air exchange, and final injection of 18% perfluoropropane (C3F8). Scleral buckles were not used.

A-scan quantitative echography of senile cataracts and correlation with phacoemulsification parameters.

Purpose: To study the echographic appearance of various types of senile cataracts using a-scan quantitative echography and correlate these findings with phacoemulsification parameters indicating surgical lens hardness.

Methods: The study involved 71 eyes with senile cataracts and 20 additional eyes with normal human lenses. Cataract and clear lenses were studied using A-scan quantitative echography and with a tissue sensitivity gain setting of 74 db.

Removal of the internal limiting membrane under perfluorocarbon liquid to treat macular-hole-associated retinal detachment.

Purpose: To demonstrate the advantages and efficacy of internal limiting membrane removal under perfluorocarbon liquid in macular-hole-associated retinal detachment.

Design: Interventional case series.

Method: Four patients with macular-hole-associated retinal detachment underwent pars plana vitrectomy, retinal reattachment with endodrainage through the macular hole, perfluoro-n-octane injection to seal the macular hole, indocyanine green injection under the perfluoro-n-octane bubble and removal of the indocyanine green-stained internal limiting membrane.

Sulcus implantation of a 3-piece, 6.0 mm optic, hydrophobic foldable acrylic intraocular lens in phacoemulsification complicated by posterior capsule rupture.

To evaluate the safety of implanting a 3-piece, 6.0 mm optic, foldable acrylic intraocular lens (IOL) in cases of posterior capsule rupture during phacoemulsification.
