The Effect of Amniotic Membrane Transplantation or Conjunctival Autografts on the Tear Mucins MUC5A and MUC2 After Pterygium Resection: A Six-Month Follow-Up.

Purpose: Pterygium is an ocular surface disease characterized by the invasion of fibrovascular tissue from the bulbar conjunctiva to the cornea and is associated with abnormal tear function caused by changes in tear composition and osmolarity. In this study, the effect of two different surgical techniques to remove primary pterygium: conjunctival autograft surgery (CAG) and amniotic membrane transplantation (AMT), on changes in MUC2 and MUC5AC tear mucins concentration were evaluated.

Methods: Forty-four patients (>18 years old) with primary unilateral pterygium (> 1.

Oral selenium improved the disease activity in patients with mild Graves' orbitopathy.

Background: Graves' orbitopathy (GO) is the most common extrathyroidal manifestation of Graves' disease (GD), an autoimmune disorder arising from the activity of T lymphocytes against antigens that infiltrate thyroid tissue, orbital tissue and extraocular muscles. An increase in oxidative stress has been discovered in autoimmune thyroid disease, encouraging investigation into new forms of treatment. Selenium has been described as a treatment option given its antioxidant properties.

Primary adenoid cystic carcinoma arising from an ectopic lacrimal gland involving both nasal orbits: a rare clinical entity.

Adenoid cystic carcinoma (ACC) is a slow-growing, locally invasive tumor of epithelial origin. The common sites of origin are the minor and major salivary glands and also the lacrimal glands. ACC accounts for 4.

Management of Ocular Surface Squamous Neoplasia with Topical and Intralesional Interferon Alpha 2B in Mexicans.

Introduction: Ocular surface squamous neoplasia (OSSN) is the most common nonpigmented ocular surface neoplasm and it can originate from the conjunctiva and/ or corneal epithelium. Since the rate of recurrence after surgical excision is high, chemotherapeutic and immunotherapeutic agents such as interferon alpha-2b (IFN α-2b) have been used for its treatment.

Objective: Our objective is to describe the demographic variables of patients with OSSN treated with IFN α-2b and to describe the outcomes of its use in Mexican patients, treated between 2011 and 2017 at Instituto de Oftalmología Fundación Conde de Valenciana.

Eyelash hair transplantation with strip composite eyebrow graft: an enhancing technique in tarsoconjunctival flap eyelid reconstruction procedure.

: To describe and evaluate the eyelash transplantation with strip composite eyebrow graft to improve eyelid anatomy in tarsoconjunctival flap eyelid reconstruction procedure. : Twenty two patients with eyelid tumors managed by local excision and reconstruction using tarsoconjunctival flap reconstruction procedure were included. Eyelash graft was performed during flap division by harvesting a graft from the eyebrow and creating a recipient pocket in the receptor eyelid.

Alveolar soft part sarcoma of the orbit, a case report of a rare tumor.

Background: Alveolar Soft Part Sarcoma is a rare malignant tumor of uncertain histogenesis, representing 0.5-1% of all soft tissue tumors. It occurs predominantly in head and neck regions, especially the orbit and the tongue, in infants, causing no specific symptoms for an extended period of time.

[Management of upper eyelid retraction associated with dysthyroid orbitopathy during the acute inflammatory phase with botulinum toxin type A].

Purpose: To evaluate the efficacy of transconjunctival botulinum toxin type A (BTX-A) in the treatment of upper eyelid retraction in the active inflammatory phase of dysthyroid orbitopathy, establish the ideal dose, and evaluate side effects.

Methods: This is a comparative, prospective study in patients with thyroid orbitopathy, conducted at the Conde Ophthalmology Institute in Valenciana, Mexico. The patients included had dysthyroid orbitopathy in the inflammatory phase, and they were treated with subconjunctival injection of botulinum toxin type A (BTX-A) in the upper eyelid.

Triple subconjunctival bevacizumab injection for early corneal recurrent pterygium: one-year follow-up.

Purpose: The aim of the study was to evaluate the effect of 3 subconjunctival bevacizumab injections in patients with an early corneal pterygium recurrence.

Methods: This study was a nonrandomized single center trial. Patients with an early corneal pterygium recurrence were selected.

Randomized, controlled trial of conjunctival autografting combined with subconjunctival bevacizumab for primary pterygium treatment: 1-year follow-up.

Background: To investigate the efficacy and safety of subconjunctival bevacizumab application as an adjuvant therapy for primary pterygium.

Design: This study was a clinical randomized trial performed at the Institute of Ophthalmology 'Conde de Valenciana'.

Participants: Forty-nine patients with primary pterygium were enrolled in the study.

Two different PABPN1 expanded alleles in a Mexican population with oculopharyngeal muscular dystrophy arising from independent founder effects.

Background: Oculopharyngeal muscular dystrophy (OPMD) is a late onset hereditary myopathy of autosomal dominant transmission characterised by ptosis, dysphagia and limb weakness. The disease is caused by short heterozygous expansions of a (GCN)(10) triplet located in the first exon of the PABPN1 gene at chromosome 14q11.1.

[Comparative study of amniotic membrane transplantation, with and without simultaneous application of mitomycin C in conjunctival fornix reconstruction].

Objective: To describe the results of amniotic membrane (AM) transplantation, using the simultaneous application of 0.02% Mitomycin C (MMC), in conjunctival fornix reconstruction.

Material: We compared two groups of patients: group A, who were treated only with AM and group B, in whom MMC (0.
