A 5-year analysis of endothelial penetrating keratoplasty graft survival in Chinese patients.

Aim: To determine if there is any difference in long term graft survival between Descemet's stripping endothelial keratoplasty (DSEK) and penetrating keratoplasty (PK).

Methods: A retrospective 5-year cases analysis of bullous keratopathy secondary to Fuchs' endothelial dystrophy or pseudophakic bullous keratopathy, receiving either DSEK or PK. A total of 42 DSEK cases and 25 PK cases were included in the analysis.

Novel grid and sectoral analyses in monitoring corneal scars.

Purpose: We aim to design two sampling methods, the grid and sectoral methods, to provide more precise detection of focal corneal scar changes with time following pterygium excision with the Pentacam imaging system.

Methods: This is a retrospective study of our previous prospective observational case series. Thirty patients underwent primary pterygium excision with adjuvant topical mitomycin-C application were followed up and imaged with Pentacam system at postoperative weeks 1, 4, 12 and month 18.

Long-Term Density Changes in Corneal Layers After Primary Pterygium Excision With Topical Mitomycin-C.

Purpose: To evaluate the long-term change in average corneal densities at 18 months after primary pterygium excision with topical adjuvant mitomycin-C application, particularly the relationship between anterior and posterior corneal layer densities.

Methods: Prospective observational case series. Patients were imaged with the Pentacam at 18 months after their surgery.

The Incidence of Postoperative Endophthalmitis Before and After a Revised Preoperative Surgical Site Preparation Protocol.

Purpose: To compare the incidence of postoperative endophthalmitis before and after the implementation of a preoperative surgical site preparation protocol for cataract surgery.

Design: Retrospective cohort study.

Methods: Records of patients with postoperative endophthalmitis between January 2006 and August 2013 were reviewed.

Human Ocular Dirofilariasis in Hong Kong.

Purpose: Human dirofilariasis is a helminthic infestation caused by filarial nematodes of the genus Dirofilaria. We report two cases of subconjunctival dirofilariasis in adult Chinese patients.

Case Reports: Case 1: A 57-year-old woman presented to us with 1-day history of left eye redness and migratory foreign body sensation.

The value of preprocedure computed tomography for planning insertion of inferior vena cava filters.

Purpose: To determine if valuable information could be obtained from abdominal computed tomography (CT) performed before insertion of an inferior vena cava (IVC) filter.

Materials And Methods: A retrospective review was performed on IVC filter insertions with a CT performed before the procedure. Cavagram and CT were compared for renal vein and IVC anatomy, the diameter of the IVC, and the prevalence of iliocaval thrombus.
