Swati Singh, Arnav Ghosh, Suryasnata Rath
This article reports proximal lacrimal system parameters using Anterior Segment Optical Coherence Tomography (ASOCT-Visante) in an apparently normal Asian Indian population with assessment of any correlation between tear meniscus height and punctal diameter. This was a prospectively designed observational study that included healthy adults, who volunteered for optical coherence tomography imaging (OCT) of their proximal lacrimal system. Time domain ASOCT (Visante) images of the punctum and proximal canaliculus were captured using the high resolution corneal scan protocol...

This article evaluates retaining bicanalicular silicone nasolacrimal tube in patients susceptible to restenosis after punctoplasty. Sixty-nine eyes (38 patients) suffering from epiphora due to stenosis or occlusion of both punctae were included in this prospective study. All had 3 snip punctoplasty and bicanalicular silicone nasolacrimal duct insertion. Cases associated with proximal canalicular stenosis or obstructions were excluded. Tolerance to tube presence until the time of loss or removal was evaluated using a score (0 to 2)...

Hemifacial spasm has been previously shown to result in dry eye and ocular surface diseases. This study was performed to assess the impact of chemodenervation with botulinum toxin on clinically-relevant metrics of tears. Tear osmolarity and lipid layer thickness were measured in patients with hemifacial spasm after they achieved relief from hemifacial spasm via botulinum toxin injections. Twelve eyes of 6 patients with hemifacial spasm (2 men and 4 women; mean age 55.5 years) were assessed in accordance with the Declaration of Helsinki and IRB approval...

Prostate carcinoma is a common tumor of the older adult male. It is associated with bony metastases, particularly to the axial skeleton. We present two case histories; in both cases, the patients had no prior history of prostate carcinoma. Both cases were diagnosed with CT imaging, elevated PSA, and biopsy. Additionally, they were treated with surgical resection and hormone modulation therapy. While bony metastases are frequently associated with advanced disease, they can also be a cause of presenting symptoms...

This article examines the clinical presentation of ocular metastasis from an infiltrating lobular breast carcinoma. We examined a conjunctival biopsy from a 69-year-old woman who developed unilateral conjunctival inflammation together with a neurotrophic corneal ulcer and proptosis. Infiltrating lobular breast carcinoma (ILBC) was diagnosed using routine histology and immunohistochemistry. She had a past history of a hormone receptor-positive infiltrating ILBC 11 years ago with cutaneous and diffuse osteoblastic metastases, and she was kept under treatment with lezotrol...

The orbit can be affected by unique pathologic conditions and often requires MRI evaluation. The purpose of this study was to investigate the age-related changes in multiple intra-orbital structures using quantitative MRI (qMRI). Thirty-eight subjects (20 males, 18 females; ages 0.5-87 years) underwent MRI with a mixed turbo spin echo sequence. T1 and T2 measurements were obtained within ROI in 6 intra-orbital structures (medial and lateral rectus muscles, medial and lateral retrobulbar fat, lacrimal gland, and optic nerve), and compared with those of corresponding extra-orbital structures (masseter muscle, subcutaneous cheek fat, buccal fat, parotid gland, and frontal white matter)...

Ocular prosthesis is either a readymade stock shell or custom made prosthesis (CMP). Presently, there is no other technology available, which is either superior or even comparable to the conventional CMP. The present study was designed to fabricate ocular prosthesis using computer aided design (CAD) and rapid manufacturing (RM) technology and to compare it with custom made prosthesis (CMP). The ocular prosthesis prepared by CAD was compared with conventional CMP in terms of time taken for fabrication, weight, cosmesis, comfort, and motility...

The purpose of this study is to examine orbital lesions identified on preoperative radiologic imaging as cavernous venous malformations (CVMs), identify their imaging characteristics, and determine if these may help differentiate CVMs from other intraorbital masses. An IRB-approved retrospective chart review over 30 years was undertaken identifying lesions "consistent with cavernous hemangioma" on radiologic studies, which were subsequently surgically resected with a tissue diagnosis. All radiologic images (CT and MRI) obtained preoperatively were re-reviewed by a single masked neuroradiologist...

We determine whether age is a prognostic factor for surgical outcomes of external dacryocystorhinostomy (Ex-DCR). This retrospective cohort study conducted at Tilganga Institute of Ophthalmology (Kathmandu, Nepal) compared pediatric Ex-DCR procedures (age ≤ 15 years) to adult Ex-DCR procedures (age > 15 years) and was performed between January 2013 and December 2013, with a minimum follow-up period of 6 months. Primary outcome measure was rate of success, defined as complete resolution of subjective symptom(s) of epiphora (subjective success), combined with patent lacrimal passage on syringing (anatomical success) at last follow-up visit...

Olfactory neuroblastoma is a rare and often locally aggressive malignancy that invades the orbit via local destruction. It is known to recur in a delayed fashion, particularly to the neck lymph nodes. This is a case of a 65-year-old gentleman who presents with recurrence in the orbit and a neck lymph node 19 years after treatment for his initial disease. This report describes the longest known interval in orbital recurrence and should alert the monitoring physician that extreme delays in recurrence can occur...

We report the clinical presentation, radiography, and management outcomes of autoenucleations (AE). Charts of 7 patients evaluated at 4 institutions with AE were reviewed. Four males and three females had a mean age of 50 years (range 26-72 years). The etiologies were psychosis secondary to underlying mental illness (6, 88%) and substance use (1, 12%), and the mechanism was largely blunt digital injury (6, 88%). Three (43%) AE patients suffered bilateral enucleations. Common concomitant injuries included eyelid lacerations (5, 71%) and optic nerve avulsion (3, 43%)...

Primary intraorbital ectopic meningiomas are rare and their existence remains controversial. We present a 30-year-old female with painless, non-axial proptosis and a palpable superomedial mass. The MRI demonstrated that the mass had no optic nerve sheath or sphenoid wing involvement and was initially reported to have no intracranial extension. The patient was initially thought to have an ectopic orbital meningioma. Subsequent multidisciplinary team (MDT) consultation and further specialist review of the MRI revealed a subtle dural tail connecting to an enhancing mass in the olfactory groove...

Orbital cellulitis is a serious sight threatening and potentially life threatening condition which can be complicated by orbital abscess formation. Posterior subtenon (PST) injection of corticosteroid is commonly used in the treatment of posterior segment inflammation including post-operative macular oedema. We report a case of orbital abscess formation as a late complication of PST triamcinolone acetonide and discuss the presentation, diagnosis and management.
