A Custom-made Pupillometer System for Characterizing Pupillary Light Response.

Objectives: This paper presents the design and construction of a viable pupillometer system and demonstrates its merits with extensive validation tests.

Materials And Methods: A web camera was modified by removing its infrared filter and mounted on a chin rest. Light emitting diodes (LEDs) operating at infrared and visible spectra were integrated to provide background and light stimulus, respectively.

Botulinum toxin as an adjunct to monocular recession-resection surgery for large-angle sensory strabismus.

Purpose: To evaluate the result of using intraoperative botulinum toxin A (BTA) as an adjunct to monocular recession-resection surgery in the management of large-angle sensory strabismus.

Methods: The medical records of patients diagnosed with sensory strabismus with constant large-angle strabismus were reviewed retrospectively to identify those who underwent monocular recession-resection surgery combined with 5 units of BTA injection into the recessed muscle of the nonfixating eye. Surgical outcome was considered successful if the final deviation was within the range of 0-10.

Prevention of suture exposure in transscleral intraocular lens fixation: an original technique.

Background: In this retrospective study, we evaluated our surgical outcomes of transscleral intraocular lens (IOL) fixation and introduced a simple, quick, and effective method to fixate and bury the sutures in the sclera to avoid suture exposure.

Methods: Eyes were divided into 3 groups according to surgical technique. Half-thickness scleral flaps were prepared, and polypropylene suture ends were cut short in group 1 (12 eyes).

Patient-controlled analgesia and sedation with fentanyl in phacoemulsification under topical anesthesia.

Purpose: To investigate the effects of intravenous (IV) patient-controlled sedation/analgesia with fentanyl during phacoemulsification surgery under topical anesthesia.

Setting: Adnan Menderes University Medical School, Departments of Ophthalmology and Anesthesiology and Reanimation, Aydin, Turkey.

Methods: In this double-blind randomized study, 68 patients were randomly allocated to 2 groups.

Colour Doppler imaging of superior ophthalmic vein in thyroid-associated eye disease.

Purpose: One of the possible etiologies of proptosis in patients with thyroid-associated eye disease is stated to be passive orbital venous congestion caused by the occlusive and constrictive changes of the superior ophthalmic vein (SOV). In an attempt to clarify the validity of this claim, quantitative information on the flow velocity of the SOV was obtained by colour Doppler imaging in 24 patients with thyroid-associated eye disease and compared with data from the control group.

Methods: On clinical examination, ocular motility, proptosis, soft tissue involvement, and the presence of optic neuropathy were evaluated.
