Specific location of ocular adnexal lymphoma and mortality: an international multicentre retrospective study.

Aims: To examine whether the specific location of ocular adnexal lymphoma (OAL) and the American Joint Committee on Cancer (AJCC) TNM tumour stage are prognostic factors for mortality in the main OAL subtypes.

Methods: Clinical and survival data were retrospectively collected from seven international eye cancer centres. All patients from 1980 to 2017 with histologically verified primary or secondary OAL were included.

Surgical resection of orbital primitive neuroectodermal tumor without adjuvant chemotherapy.

Primitive neuroectodermal tumor (PNET) of the orbit is a very rare entity. We report a case of a 10-year-old boy having progressive protrusion of the eyeball, restricted ocular motility, ptosis, and ocular pain for 2 months. On examination, a fixed, nontender, firm, hyperemic, nonpulsatile globular mass was palpated in the superomedial quadrant of the orbit.

Deep blue dot corneal degeneration: a rare corneal degeneration.

A female patient in the age group 55-60 years presented to us with blurring of vision in both eyes. On slit-lamp examination, numerous circular to oval fleck-like discrete blue opacities at the level of deep corneal stroma and Descemet's membrane was observed. These lesions were predominantly seen in the central two-thirds of the cornea.

Evaluation of reinforced plication as an alternative to resection in exotropia.

Purpose: To evaluate the surgical efficacy of reinforced plication of the medial rectus muscle to resection as an effective muscle strengthening procedure in exotropia.

Methods: This is a prospective randomized trial in patients with exotropia who underwent complete orthoptic evaluation followed by random assignment into two groups by using a computer-drawn random number table. Group 1 patients underwent standard resection with recession procedure, and group 2 patients underwent reinforced plication with recession procedure.

Orbital dermoid cyst.

Background: Dermoid cyst, a developmental benign choristoma, is the most common orbital tumor of childhood, arising from ectodermal sequestration along the lines of embryonic fusion of mesodermal processes, lined by keratinized stratified squamous epithelium and expanding slowly due to constant desquamation and dermal glandular elements. Approximately 80% are found in the head and neck region and comprise 3-9% all orbital masses.

Purpose: It is mandatory to know about the variable presentations of orbital dermoids and the surgical techniques that can be adopted based on the site, extent, age and aesthetic needs, presence of inflammation and possibility of intraoperative rupture.

Limited pars-plana vitrectomy for optimizing surgical outcome in subluxated cataracts undergoing femtosecond laser-assisted cataract surgery.

We propose a technique for combined femto laser-assisted cataract surgery (FLACS) and limited vitrectomy from the pars-plana site for optimization of surgical results in subluxated cataracts. FLACS creates a free-floating, customised capsulotomy, minimizes stress on compromised zonules, and prechops the nucleus, effectively reducing the ultrasonic power as well as the forces required to chop the nucleus. The area of zonular dehiscence creates a direct communication between the irrigation fluid and the anterior vitreous, leading to its hydration.
