Purpose: To report a case of a perifoveal exudative vascular anomalous complex (PEVAC) resembling lesion in a patient with multiple myeloma.

Observations: A 56-year-old male with multiple myeloma presented with sudden moderate vision loss in the right eye. Best-corrected visual acuity was 20/25 in his right eye.

Purpose: To evaluate the clinical course after early surgical treatment with excision of retinal hemangioblastomas (RHs) before development of major complications.

Methods: Interventional case series of four eyes (four patients) with a peripheral RH that had not yet been treated by laser or cryotherapy prior to surgery. All eyes underwent 23-gauge vitrectomy with lesion excision.

Purpose: To update the surgical technique in which a vitrectomy is performed and a retinal branch vein is cannulated and infused with recombinant tissue plasminogen activator (RTPA) to treat central retinal vein occlusion (CRVO) in patients who present with very low visual acuity (VA).

Methods: Twelve consecutive patients (12 eyes) with CRVO and low VA (logMAR >1.00) at presentation were treated using this method.

Background: Paraneoplastic melanocytic proliferation (bilateral diffuse uveal melanocytic proliferation, BDUMP) is a rare but devastating disease that causes progressive visual loss in patients who usually have an occult malignancy. Visual loss occurs as a result of paraneoplastic changes in the uveal tissue.

Methods: In a masked fashion, the serum of two patients with BDUMP was evaluated for the presence of cultured melanocyte elongation and proliferation (CMEP) factor using cultured human melanocytes.

We report macular telangiectasia type 2 (MacTel) in a 34-year-old man, the youngest patient so far published with MacTel type 2. The patient presented with metamorphopsia and impaired reading ability. Diagnosis was based on bilateral abnormal macular autofluorescence, perifoveal telangiectasia with fluorescein angiographic hyperfluorescence without cystoid oedema, a small foveal avascular zone, asymmetric configuration of the foveal pit, disruptions in the inner segment/outer segment layer and hyper-reflective haze and spots in the outer nuclear layer.

We describe long-term fundus changes in a patient with partial lipodystrophy (PL). Retinal pigment alterations, drusen and subretinal neovascularisation were seen without evidence for membranoproliferative glomerulonephritis. Fundus alterations similar to those seen in age-related macular degeneration can occur at an earlier age in patients with PL, even without renal disease.

Aims: To investigate the efficacy and safety of a single intracameral bevacizumab injection to improve the outcome of trabeculectomy.

Methods: A 12-month, prospective, randomised, double-masked, placebo-controlled trial. Patients with medically uncontrolled open-angle glaucoma scheduled for a primary trabeculectomy were recruited and randomised to receive 50 µL of either bevacizumab (1.

Background: Several lines of evidence suggest that macular pigment may play a protective role against age-related macular degeneration, but the influence of age on macular pigment density levels remains unclear. This study was designed to investigate the relationship between age and the normal distribution of macular pigment optical density (MPOD) values surrounding the fovea.

Methods: Consecutive healthy subjects with no evidence of ocular disease were enrolled in this study.

Background/purpose: Light-chain deposition disease (LCDD) is a rare condition characterised by deposition of monoclonal immunoglobulin light chains (LCs) in tissues, resulting in varying degrees of organ dysfunction. This study reports the characteristic clinical ocular findings seen in advanced LCDD upon development of ocular fundus changes. This is the first report to describe this entity in vivo in a series of patients.

Purpose: The purpose of this study was to report vertical transmission of macular telangiectasia type 2 and type 2 diabetes mellitus in 3 families.

Methods: In this retrospective interventional case series, the charts of patients with inherited macular telangiectasia type 2 were reviewed. A large spectrum of presentations of macular telangiectasia type 2 was observed and has been studied with different techniques including best-corrected visual acuity, microperimetry, confocal blue reflectance fundus autofluorescence, fluorescein angiography, and time domain and spectral domain optical coherence tomography.

Purpose: The purpose of this study was to report diving-related visual loss in the setting of angioid streaks.

Methods: Observational case reports of two patients with angioid streaks suffering sudden visual loss immediately after diving.

Results: Two young adult male patients presented with visual loss after diving headfirst.

Background And Objective: To determine the normal ultrasonographic thickness of the iris and ciliary body.

Patients And Methods: This prospective 35-MHz ultrasonographic study included 80 normal eyes of 40 healthy volunteers. The images were obtained at the 12-, 3-, 6-, and 9-o'clock radial meridians, measured at three locations along the radial length of the iris and at the thickest section of the ciliary body.

Purpose: To investigate the benefit of preoperative treatment with either topical nonsteroidal anti-inflammatory drug (NSAID) or steroid in terms of clinical outcomes following trabeculectomy.

Design: Prospective, randomized placebo-controlled trial.

Participants: Sixty-one patients.

Background: The combination of verteporfin photodynamic therapy (PDT) and anti-angiogenics has been shown to be safe and efficacious in the treatment of choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The purpose of this study is to demonstrate long-term prevention of vision loss and improvement in best-corrected visual acuity (BCVA) after treatment with one-time reduced-fluence-rate PDT followed by administration of ranibizumab on a variable dosing regimen over 24 months in patients with neovascular AMD. Secondary outcome measures included the change in central macular thickness (CMT), reinjection frequency, and safety.
