Scleral thickness in normal Indian eyes measured using spectral domain anterior segment optical coherence tomography.

Purpose: To establish normative data on anterior scleral thickness using the spectral domain anterior segment optical coherence tomography (AS-OCT).

Methods: In total, 200 eyes of 100 healthy subjects underwent AS-OCT scans in the temporal and nasal quadrants. The scleral + conjunctival complex thickness (SCT) was measured by a single examiner.

Assessment of trace metal contamination in the core sediment of Ramsar wetland (Kabar Tal), Begusarai, Bihar (India).

The concentration of trace metals Mn, Pb, Ni, Zn, and Cu in the core sediment from Kabar Tal wetland was analyzed to understand the level of contamination in the vertical profile. Additionally, total organic carbon (TOC) and available phosphorus (AP) were also analyzed to infer the biogeochemistry of trace metals and the correlation that exists among them. Five core sediments were collected at the end of the monsoon season from different locations in the study area, representing diverse anthropogenic and agricultural activities.

Lupus miliaris disseminatus faciei: A resistant case with response to cyclosporine.

Lupus miliaris disseminatus faciei (LMDF) is a chronic, inflammatory dermatosis of unknown etiology, characterized by multiple, monomorphic, symmetrical, reddish-brown papules over forehead, cheeks, and eyelids. Histopathology shows perifollicular epitheloid cell granuloma. Though numerous therapies, ranging from cyclines, macrolides, dapsone tranilast, isotretinoin, steroids, and tacrolimus have been tried, the results are inconsistent, except with systemic steroids.

A Comparative Study of Two Modalities, 4% Hydroquinone Versus 30% Salicylic Acid in Periorbital Hyperpigmentation and Assessment of Quality of Life Before and After Treatment.

Background: Periorbital hyperpigmentation (POH) is a common hyperpigmentary problem of the face, which can be psychologically distressing and it can influence an individual's quality of life. However, this condition has received less attention in literature.

Aims And Objectives: To study the clinico-etiological features and the effect of two therapeutic modalities on the quality of life in patients of POH before and after treatment.

Periorbital Hyperpigmentation: A Comprehensive Review.

Periorbital hyperpigmentation is a commonly encountered condition. There is very little scientific data available on the clinical profile and pathogenesis of periorbital hyperpigmentation. Periorbital hyperpigmentation is caused by various exogenous and endogenous factors.

Optimising laser tattoo removal.

Lasers are the standard modality for tattoo removal. Though there are various factors that determine the results, we have divided them into three logical headings, laser dependant factors such as type of laser and beam modifications, tattoo dependent factors like size and depth, colour of pigment and lastly host dependent factors, which includes primarily the presence of a robust immune response. Modifications in the existing techniques may help in better clinical outcome with minimal risk of complications.

A rapid tattoo removal technique using a combination of pulsed Er:YAG and Q-Switched Nd:YAG in a split lesion protocol.

Background: Tattoo removal has evolved over the years and though Q-switched laser is the 'workhorse' laser, it invariably requires multiple sittings, which are dependent on numerous factors, including the skin colour, location of the tattoo, age of the tattoo, colour of pigment used, associated fibrosis and the kind of tattoo treated. Though ablative lasers, both pulsed CO2 and Er:YAG, have been used for recalcitrant tattoos, very few studies have been done comparing them with pigment-specific lasers. Our study was based on the premise that ablating the epidermis overlying the tattoo pigment with Er:YAG could help in gaining better access to the pigment which would enable the Q-switched laser to work effectively with less beam scattering.

Lipoid Proteinosis: a case report in two siblings.

Lipoid proteinosis was first reported by Urbach and Wiethe in 1929. It is also known as hyalinosis cutis et mucosae or Urbach-Wiethe disease. It is a rare autosomal recessive disorder and characterized by the infiltration of hyaline material in the skin, oral cavity, larynx, and internal organs.
