Nodular Posterior Scleritis Mimicking Non-pigmented Choroidal Melanoma: A Case Report and Literature Review.

Nodular posterior scleritis is an uncommon inflammatory disorder of the eye characterized by nodular lesions that may be similar to other intraocular conditions such as choroidal melanoma, leading to diagnostic difficulties. This case report and literature review aims to evaluate the demographics, modalities, treatment, and outcomes of nodular posterior scleritis. We describe a 41-year-old female patient who presented with diminished vision in her left eye.

Outcomes of Toric Iris-Claw Phakic Intraocular Lens Implantation After Deep Anterior Lamellar Keratoplasty for Keratoconus.

Purpose: To assess visual and refractive outcomes of toric iris-claw phakic intraocular lens (IOL) implantation in patients who had previously undergone deep anterior lamellar keratoplasty (DALK).

Methods: Retrospective case series including 24 eyes of 24 patients implanted with toric Artiflex or Artisan (Ophtec BV, Groningen, Holland) phakic IOL following DALK for keratoconus. During a 12-month follow-up, the main outcome measures were uncorrected and corrected distance visual acuities (UDVA and CDVA), refractive error components, topographic parameters, and endothelial cell count.

Keratopigmentation to Change the Apparent Color of the Human Eye: A Novel Indication for Corneal Tattooing.

Background: Recently developed surgical techniques of keratopigmentation, assisted by femtosecond laser technology, using adequately developed micronized mineral pigments, have been reported to be efficient and conveniently safe as they are not associated with significant sight-threatening complications for changing the apparent color of the eye in cases of cosmetic therapeutic and functional keratopigmentation. We report the use of intrastromal keratopigmentation for electively changing the apparent color of the eyes, for purely cosmetic reasons.

Methods: In a case series, 7 patients underwent purely cosmetic keratopigmentation to change the apparent color of the eye.

Refractive surgery following corneal graft.

Purpose Of Review: To review the different surgical procedures for management of postkeratoplasty refractive errors after total suture removal.

Recent Findings: There are different surgical options to address residual refractive errors that frequently occur after corneal transplantation. The correction can be done on the corneal surface or intraocular with intraocular lens (IOL) implantation which requires complete tectonic and refractive stability after suture removal.

A new epidescemetic keratoprosthesis: pilot investigation and proof of concept of a new alternative solution for corneal blindness.

Purpose: To report the outcomes of a new model of epidescemetic keratoprosthesis (Kpro) implanted without total corneal trephination.

Methods: Patients were considered for implantation with the new Kpro model (KeraKlear) if they were at high risk of failure with standard penetrating keratoplasty (PK) or showed conditions with a poor prognosis following PK such as severe chemical injury. We used femtosecond laser to create the surgical planes adequate for the purpose of the Kpro implantation, and the Kpro was implanted intralamellar in 11 eyes and epidescemetical in 4 eyes.

Comparison of iris-claw and posterior chamber collagen copolymer phakic intraocular lenses in keratoconus.

Purpose: To evaluate the visual and refractive outcomes, predictability, and stability of phakic intraocular lens (pIOL) implantation in keratoconic eyes and compare the results of 2 pIOL models.

Setting: Vissum Instituto Oftalmologico, Alicante, Spain.

Design: Retrospective case series.

MICS with toric intraocular lenses in keratoconus: outcomes and predictability analysis of postoperative refraction.

Aims: To investigate the visual and refractive outcomes, safety, efficacy and stability of cataract surgery in eyes with stable keratoconus.

Methods: 17 eyes (10 patients) diagnosed as stable keratoconus, aged from 34 to 73 years (56.63 ± 12.

Touch-less heartbeat detection and measurement-based cardiopulmonary modeling.

This paper presents a system for touch-less heartbeat detection and a cardiopulmonary signal modeling approach. Using a vector network analyzer, a microwave system is tested for the detection of the heartbeat signal at a distance of 1 m from a person. The proposed system shows the ability of detecting the heartbeat signals with the possibility of tuning both frequency and power.

Multiple sclerosis-associated uveitis.

Background/aims: To describe the clinical characteristics and course of 16 patients with uveitis associated with multiple sclerosis (MS).

Methods: The records of 1254 patients with uveitis were reviewed. Sixteen of these patients had MS.

Ocular cicatricial pemphigoid: pathogenesis, diagnosis and treatment.

Understanding of ocular cicatricial pemphigoid (OCP) has changed dramatically over the last three decades. Progress in basic science research in mucous membrane pemphigoid has been instrumental in outlining the key immune processes that participate in the autoimmune response. Immunomodulatory therapy has provided an avenue for preserving vision and preventing potentially fatal consequences of systemic pemphigoid.

Neurofibromatosis type 1 associated with central nervous system lymphoma.

Purpose: To report the occurrence of central nervous system (CNS) lymphoma in a patients with neurofibromatosis type 1 (NF1).

Design: Interventional case report.

Methods: A 47-year-old male with a parieto-occipital lobe lesion was referred for ocular evaluation.

Characterization of insulin-resistance: role of receptor alteration in insulin-dependent diabetes mellitus, essential hypertension and cardiac hypertrophy.

Insulin-resistance is associated with a number of disease states such as diabetes, syndrome X, and hypertension. These situations may be coupled to insulin-resistance through the insulin signaling system as a common pathway. The purpose of this study was to investigate the receptor binding alterations in streptozotocin-induced diabetic rats, spontaneously hypertensive rats and aortocaval shunted rats (eccentric cardiac hypertrophy).

[Cryptophthalmos solum corneae].

The authors report on an 11-month-old child in whom subcutaneous fatty tissue covered with normal skin was found instead of a cornea. Since the lid and conjunctiva were intact this developmental anomaly may be designated cryptophthalmos solum corneae.

The dynamics of the steroidogenic response of perifused Xenopus ovarian explants to gonadotropins.

Steroid release before and during maturation was studied in Xenopus ovarian follicles under various conditions of stimulation of LH in a perifusion system. Acute stimulation by 15 micrograms of LH induces a 10-fold increase in the androgen (testosterone and androstenedione) level which reaches a maximum 4 hr later and then slowly decreases until the 25th hour. Repeated stimulations every 2 or 4 hr are followed by the same androgen increase during the first 8 or 10 hr and then by a slow decrease in the secretion despite new LH injections.

Studies on fish protein concentrate and fish meal from river Nile bolti fish (Tilapia nilotica).

Fish protein concentrate (FPC) from river Nile bolti fish (Tilapia nilotica) was prepared and compared with commercial FPC and fresh bolti fish flesh. Fish meal (FM) from bolti fish offals was prepared and compared with commercial FM and also fresh bolti fish flesh. FPC from bolti fish showed a higher crude protein content but less fat, ash, calcium and sand than the commercial sample, while FM from bolti fish showed a higher content of ash and phosphorus than commercial FM but was nearly similar in crude protein, fat, calcium and sodium chloride.
