PURPOSE To investigate the association between ocular biometrics such as axial length (AL), anterior chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD) and corneal power (CP) with different refractive errors. METHODS In a cross-sectional study on the 40 to 64-year-old population of Shahroud, random cluster sampling was performed. Ocular biometrics were measured using the A...

We read with great interest the recently published article “Extraction of Iron from the Rabbit Anterior Chamber with Reverse Iontophoresis” by Sun et al. [1]. In this experimental study, researchers aimed to use reverse iontophoresis (RI) to extract iron from the anterior chamber noninvasively. However, we think that there are some points that should be emphasized and reconsidered about this st...

BACKGROUND In 2014, Pang et al. reported three cases with vitelliform submaculopathy as a preceding lesion of primary intraocular lymphoma (PIOL). Here, we report a case with an atypical presentation of PIOL who initially presented with vitelliform submaculopathy, vitreous haze and preripheral retinal focus. CASE PRESENTATION A 73-year-old female initially visited another hospital with a chie...

The permeability of the blood-ocular barrier was investigated in five monkeys using vitreous fluorophotometry (VFP). Inward permeability (Pin) of the blood-retinal barrier was calculated by a computer simulation method. Kinetic VFP was performed after intravitreal injection of fluorescein (F) or fluorescein monoglucuronide (FG). The estimated mean value of Pin (x10(-6) cm/min) was 4.8 (SD 1.2)....

Introduction: Ghost cell glaucoma (GCG) is a very rare secondary open angle glaucoma, in which there sustained increase intraocular pressure (IOP) due to obstruction of the trabecular meshwork (TM) passage ghost cells (GC) from vitreous into anterior chamber, after hemorrhage (VH). Clinical Case: We present case male patient with history and IOP elevation right eye (RE). Medical treatment was i...

influence on its volume. For, from the physico-chemical point of view the vitreous body belongs to the hydrophil emulsoids and it is known that the degree of swelling of such emulsoids is dependent, among otlher factors, chiefly on the acid-base equilibrium and that, within certain limits, the lower the hydrogen ion concentration the greater is the swelling. It would seem, therefore, that in th...

To observe curative effects of phacoemulsification combined with intraocular lens implantation alone or associated with vitreous aspiration in treating angle closure glaucoma (ACG) patients with concomitant cataract. A retrospective comparative analysis of 72 ACG patients (78 eyes) with concomitant cataract was conducted. Patients in group A underwent phacoemulsification combined with intraocul...

BACKGROUND Ozurdex is a 700 mcg dexamethasone intravitreal implant, approved for the management of macular edema secondary to retinal vein occlusion, and other related pathoglogiesAnterior chamber dislocation of Ozurdex represents an uncommon complication of the intravitreal injection, which can be managed by repositioning the implant into the vitreous cavity. We describe the case of a successf...

Vitreous cysts are very rare ocular malformations. In this observational case study, we report on an unusual case of a pigmented free-floating vitreous cyst and discuss its differential diagnosis. A 14-year-old male was referred to ophthalmology for a pigmented lesion in his left eye. He complained of an intermittent floater in the left eye. Visual acuity was 20/20 in the right eye and 20/40 in...
