IOP and SOV-BFV have significant association with the clinical features of Graves' orbitopathy. The decrease in SOV-BFV increases the severity of Graves' orbitopathy, and may have a role in the clinical course of dysthyroid optic neuropathy.

BackgroundVitiligo is a disease characterized by depigmented macules and patches that occur as a result of the loss of functional melanocytes from the affected skin through a mechanism which has not been elucidated yet. Destruction of pigment cells in vitiligo may not remain limited to the skin; the eyelashes, iris, ciliary body, choroid, retinal pigment epithelium and meninges may also be affected. This study aims to compare the choroidal thickness of patients with and without vitiligo using optical coherence tomography (OCT).MethodsSpectral-domain optical coherence tomography (SD-OCT) (Retina Scan Advanced RS-3000 NIDEK, Japan) instrument (with λ = 840 nm, 27,000 A-scans/second and 5 μm axial resolution) was used for the imaging. Statistical analysis was performed using SPSS 21.0 software package.ResultsIn all values except optic nevre area measurements, the choroidal thickness of all vitiligo patients was found out to be thinner compared to the control group.ConclusionsIn vitiligo, the choroidal thickness may be affected by the loss of melanocytes.

Different CCT measurement techniques produce quite different results, so CCT evaluation and follow-up should be performed using the same device or devices with close compatibility.

Combined orbital bone and fat decompression significantly reduced the IOP levels and increased the SOV-BFV in GO. This could be the confirmative finding of prediction that elevated IOP in GO is associated with increased episcleral venous pressure. The post-operative changes in IOP and SOV-BFV show differences regarding the clinical features of disease.

Silent sinus syndrome is a clinical entity with the constellation of progressive enophthalmos and hypoglobus due to gradual collapse of the orbital floor with opacification of the maxillary sinus, in the presence of subclinical maxillary sinusitis. It occurs secondary to maxillary sinus hypoventilation due to obstruction of the ostiomeatal unit. In this paper, a 35-year-old woman with a complaint of asymmetry in her left eye and denting of upper eyelid was reported. In the left eye, upper sulcus was deepened and there was 3-mm hypoglobus. There was no diplopia or restriction of eye movements in any gaze positions. Hertel exophthalmometry revealed a 4-mm enophthalmos on the left eye. Computed tomographic scan of the orbita and paranasal sinuses showed left maxillary sinusitis, air-fluid level, and collapse of left maxillary sinus walls. In addition, inferior bulging in the left orbital floor was also reported. The treatment was a 2-stage operation. In the first stage, she underwent endoscopic septoplasty plus left maxillary antrostomy, and in the second stage, she underwent a subciliary orbital floor repair of the iliac bone resulting in the improvement of the enophthalmos and her cosmetic appearance. Regarding this case, the literature is also reviewed in detail.

A 13-year-old girl presented with a history of a slowly enlarging, mobile, right lower eyelid mass of 2 years' duration. Excisional biopsy revealed the characteristic histopathologic features of a schwannoma. After complete excision, there was no recurrence at 1-year follow-up. Schwannoma is a rare eyelid tumor, appearing sporadically and in a solitary form, which should be considered in the differential diagnosis of eyelid tumors in children.

In this report, we are presenting a case in which we have split the paramedian forehead flap, thus providing 2 axially perfused skin flaps for simultaneous reconstruction of the upper and lower lid structures after resection of basal cell carcinoma from the left medial canthal area. We found that split forehead flap seems to be a favorable option for simultaneous reconstruction of the upper and lower eyelid defects by enabling nicely vascularized and abundant amount of regional skin.
