Purpose: To evaluate the visual outcomes and macular thickness change in patients with symptomatic chronic central serous chorioretinopathy after treatment with a subthreshold MicroPulse diode laser.

Methods: In this retrospective, interventional case series, 10 patients were treated with the subthreshold 810-nm diode MicroPulse laser. Selected patients had symptomatic disease that may or may not have involved the foveal center.

Background And Objective: Little is known about the accuracy and precision of syringes used to deliver small-volume intravitreal injection of medication. The authors investigated the accuracy and reproducibility of seven brands of small-volume syringes used for intravitreal injection.

Materials And Methods: This experimental laboratory investigation compared EXELint 1 cc TB, BD Luer-lok, BD 1 cc TB, Kendall Monoject TB, Nipro TB, Terumo 1 cc, and Terumo 0.

Purpose: To assess the visualization of the retinal microvasculature with intravenous fluorescein angiography (IVFA) compared to the Retinal Function Imager (RFI).

Design: Multicenter, retrospective, observational case series.

Methods: Seven normal eyes and 26 eyes with various ocular diseases were imaged with both IVFA and the RFI.

Purpose Of Review: Over the past few years, the results of many studies have highlighted the risks and benefits of intravitreal injection of a number of medications, the most common being triamcinolone, antivascular endothelial growth factor (VEGF) agents, antibiotics, antivirals, antifungals, and methotrexate. The purpose of this review is to highlight the complications associated with these injections.

Recent Findings: Elevated intraocular pressure and glaucoma are the most common complications of intraocular triamcinolone.

Purpose: To identify the genetic basis of Schnyder crystalline corneal dystrophy (SCCD) through screening positional candidate genes and UBIAD1, in which mutations have been associated with SCCD, in affected families.

Methods: The coding region of each of the 16 positional candidate genes for which mutation screening has not been previously reported was screened with polymerase chain reaction (PCR) amplification and automated sequencing in four affected individuals from two families with SCCD. In addition, the coding region of UBIAD1, located just outside of the originally described SCCD candidate interval on chromosome 1p36, was directly sequenced in affected and unaffected individuals from three families with SCCD.

Mutations in the two-handed zinc-finger homeodomain transcription factor gene (TCF8) have been associated with posterior polymorphous corneal dystrophy (PPCD) and extraocular developmental abnormalities. We performed screening of TCF8 in 32 affected, unrelated probands, affected and unaffected family members of probands identified with a TCF8 mutation, and in 100 control individuals. Eight different pathogenic mutations were identified in eight probands: four frameshift (c.

Purpose: To identify the genetic basis of posterior polymorphous corneal dystrophy (PPCD) through screening of four positional candidate genes and the COL8A2 gene, in which a presumed pathogenic mutation has previously been identified in affected patients.

Methods: DNA extraction, PCR amplification, and direct sequencing of the COL8A2, BFSP1, CST3, MMP9, and SLPI genes were performed in 14 unrelated, affected patients and in unaffected family members.

Results: In the COL8A2 gene, the previously identified, presumed pathogenic mutation (Gln455Lys) was not discovered in any of the affected patients.
