Purpose: The purpose of this study was to describe the response of a papillomatous ocular surface squamous neoplasia (OSSN) to the intramuscular (IM) 9-valent human papillomavirus (HPV) vaccine after failed medical and surgical interventions.

Methods: A 79-year-old White man with a conjunctival lesion underwent a biopsy which revealed OSSN and positivity for high-risk HPV. Initially treated with medical therapy and surgical excisions, the patient developed a recurrence and refused further surgery.

Purpose: To present the first known cases of punctal and canalicular stenosis following topical 5-fluorouracil (5-FU) eye drops for ocular surface squamous neoplasia (OSSN).

Methods: A retrospective chart review of patients with OSSN receiving topical 1% 5-FU eye drops as a primary or adjuvant treatment between 2013 and 2021 was performed. Individuals diagnosed with punctal or canalicular stenosis during or after topical 5-FU use were included in this study.

The gut microbiome is a complex ecosystem in the gastrointestinal tract composed of trillions of bacteria, viruses, fungi, and protozoa. Disruption of this delicate ecosystem, formally called "dysbiosis", has been linked to a variety of metabolic and inflammatory pathologies. Several studies have focused on abnormal microbiome composition and correlated these findings with the development of type 2 diabetes mellitus (T2DM) and diabetic retinopathy (DR).

Purpose: To assess the efficacy of topical interferon α-2β(IFN) eye drops as a primary treatment for ocular surface squamous neoplasia(OSSN) and evaluate factors that impact response to treatment and recurrence of OSSN.

Method: A retrospective study of 143 OSSN patients treated with topical IFN(1MIU/ml) from January 1998 to June 2021. The diagnosis was based on clinical examination and anterior segment optical coherence tomography, with histologic confirmation was present in 46.

Purpose: To determine the efficacy and safety of topical 1% 5-fluorouracil (5FU) eye drops as primary treatment of ocular surface squamous neoplasia (OSSN).

Methods: Patients were diagnosed with OSSN based on slit-lamp examination and anterior segment optical coherence tomography (AS-OCT). In ambiguous cases an incisional biopsy was performed.

Dry eye has two basic subdivisions: aqueous deficient dry eye (ADDE), with SS a major cause; and evaporative dry eye (EDE), due to either intrinsic or extrinsic factors. SS is a chronic inflammatory disorder defined by dysfunction of the exocrine glands leading to dry eye and dry mouth. The objective of this article was to carry out a systematic and critical review of several scientific publications on dry eye disease, with the aim of providing general recommendations to distinguish dry eye and its different variants in patients with SS, during the period 1979 to 2020, using search engines for articles indexed in Scopus, Latindex, Scielo, Clinical Trials, Medline, Embase, and Cochrane, allowing the analysis of 132 articles published in indexed journals on the subject of dry eye disease and SS, evidencing its conceptualization, prevalence, risk factors, etiopathogenesis, clinical manifestations, diagnosis, and treatment.

Article Synopsis
  • The study aimed to compare the AS-OCT features of conjunctival papilloma and papilliform OSSN, focusing on how to differentiate between the two conditions based on imaging findings.
  • A chart review of 20 patients revealed that OSSN lesions were more likely to involve specific areas of the eye, and that papillomas had a greater epithelial thickness and distinct features such as an overhanging edge.
  • The research concluded that AS-OCT can effectively differentiate between conjunctival papilloma and OSSN, with the presence of an overhanging edge being the most reliable indicator for papilloma.

Purpose: To present a rare presentation of pyogenic granuloma arising almost 4 decades after a scleral buckle for retinal detachment.

Method: We describe the clinical presentation, diagnostic workup, and management of a suspicious conjunctival lesion in an immunocompromised patient. We report the histopathological findings and the postoperative outcome.

The gold-standard treatment for ocular surface squamous neoplasia (OSSN) has traditionally been surgical excision with wide margins and a no-touch technique. However, surgery may be associated with several unfavourable sequelae, as well as significant recurrence rates if margins are positive. In recent years, topical chemotherapy with 5-fluorouracil, interferon α-2b and mitomycin C have emerged as valuable agents capable of effectively treating OSSN with varying adverse effects.

Cataract surgery is one of the most common surgical procedures performed in the United States. The decision to remove a cataract is determined by the patient's ability to perform activities of daily living, such as reading, driving, and watching television. Cataract surgery also offers the potential of spectacle independence with a wide array of premium intraocular lens options.

Purpose: To find a remedy for serpiginous choroiditis refractory to oral prednisone and chlorambucil treatment.

Observations: Eight eyes of four patients (all female) with advanced macular involvement secondary to serpiginous choroiditis were included in the study. The average age of the patients was 45.

Objective: To evaluate the clinical safety and efficacy of the novel Wright hang-back recession with fibrin glue for the treatment of horizontal strabismus.

Study Design: Retrospective, case-controlled clinical study comparing surgical outcomes of the Wright hang-back rectus recession with fibrin glue (WHBG) versus standard fixed suture rectus recession (SFR).

Methods: Medical records of all patients who underwent strabismus surgery by one strabismus surgeon between 2016 and 2018 for horizontal deviations only, including cases of WHBG (group 1) or SFR (group 2), were reviewed.

Mosaic Trisomy 8 is a rare chromosomal abnormality estimated to occur one in 30,000 newborns. The phenotype is highly variable and the severity does not appear to be correlated with the proportion of cells that contain the additional chromosome. Ocular involvement in Trisomy 8 mosaicism has previously been described to include corneal opacities, retinal dystrophy, coloboma, and unilateral microphthalmia.

Soft tissue fillers are a mainstay in contemporary, minimally invasive facial rejuvenation procedures owing to timely results and minimal recovery period. Although associated with a low complication rate, soft tissue fillers are not without risk. Complications range from mild superficial skin irregularities to granuloma formation to vascular occlusion leading to skin necrosis or even blindness.

Mucous membrane pemphigoid is a systemic disorder that primarily affects mucous membranes. When localized to the conjunctiva, it is known as ocular cicatricial pemphigoid, a potentially blinding disease. Ocular cicatricial pemphigoid is an indication for systemic immunosuppressive treatment to achieve adequate remission.
