Article Synopsis
- - The study aimed to evaluate a new instrument for measuring intraocular pressure (IOP) without applying pressure to the cornea.
- - Sixteen healthy volunteers participated, and IOP was measured multiple times using both the prototype and established reference instruments, showing no significant difference overall.
- - The findings suggest that the prototype has good clinical agreement with traditional methods, but further research is needed, especially involving glaucoma patients.
Purpose: To identify risk factors for incorrect self-identification of the treatment eye before intravitreal injections.
Methods: This prospective study included consecutive patients who were asked to designate the eye for which the intravitreal injection was intended and were subsequently divided into two groups according to whether or not they identified the correct eye.
Results: Overall, 349 eyes (n = 349) were included, and 8.
Purpose: To describe a new technique for sealing small corneal perforations after penetrating trauma.
Methods: Corneal perforations in six eyes were sealed using a stromal cefuroxime hydration technique. This technique is identical to the current method used to seal leaking incisions upon completion of cataract surgery except for the use of cefuroxime instead of balanced salt solution.
Aim: To compare changes in visual acuity and macular edema in patients with central retinal vein occlusion (CRVO) treated with intravitreal injections of bevacizumab, macular grid photocoagulation combined with pan retinal photocoagulation (PRP), or both (bevacizumab+grid+PRP).
Methods: Our study is a retrospective cohort clinical study that examined patients that suffered from ischemic CRVO with macular edema. Study inclusion criteria were ischemic CRVO with macula edema and the availability of complete medical records for at least 12mo after treatment.
Objective: The aim of this study was to show possible connection between episcleritis and open-angle glaucoma.
Design: This was a retrospective study.
Materials And Methods: Data on 21 patients who suffered from episcleritis and had no previous attack of episcleritis or glaucoma were collected for a period of 8 years (from 2004 to 2011).
Purpose. Injection of anti-VEGF antibody into the vitreous body is a well-established treatment for ischemic central retinal vein occlusion (CRVO) associated macular edema. Various treatment regimens regarding the timing, number, and frequency of injections have been proposed.

Objectives: To evaluate the effect of ascorbic acid supplementation in addition to perioperative topical mitomycin-C for the prevention of haze after LASEK.
Methods: We performed a retrospective, non-randomized case series study of two groups of 48 consecutive patients (96 myopic eyes) who had LASEK surgery.
Article Synopsis
- A female patient with a long history of poorly controlled Grave's disease presented with acute distress caused by a subluxated globe.
- Previous reports suggested that this phenomenon is linked to orbital fat enlargement and normal extraocular muscles, but this case highlights significant involvement of the extraocular muscles causing complications.
- This case is the first documented instance of acute globe subluxation occurring in "myogenic" (type II) thyroid orbitopathy, emphasizing its rare occurrence.
Topical glaucoma therapy as a risk factor for nasolacrimal duct obstruction.
Am J Ophthalmol
January 2008
Purpose: To investigate a possible association between primary open-angle glaucoma (POAG) and primary acquired nasolacrimal duct obstruction (PANDO).
Design: Retrospective, comparative study.
Methods: The study group consisted of 209 consecutive eyes (178 patients) whose lacrimal system had PANDO in patients more than 50 years of age during the 10-year study period.
Effect of timing of external dacryocystorhinostomy on surgical outcome.
Ophthalmic Plast Reconstr Surg
July 2007
Purpose: To present our experience with external dacryocystorhinostomy (DCR) outcome and to compare cases of early and late DCR.
Methods: Retrospective data review of all patients who had external DCR with silicone intubation in a 7-year period. Data were collected and analyzed concerning patients' preoperative and postoperative symptoms, and the lacrimal drainage system examination before, during, and after surgery.
Orbital fractures complicated by late enophthalmos: higher prevalence in patients with multiple trauma.
Ophthalmic Plast Reconstr Surg
April 2007
Purpose: To present our experience with orbital fracture treatment outcomes in patients with multiple trauma and those suffering localized orbital trauma.
Methods: Retrospective data review of all patients examined for ocular motility problems and/or enophthalmos following orbital trauma in a 4-year period.
Results: Forty-three patients were included in the study: 31 (72%) had localized orbital trauma (LOT) and 12 (28%) had concomitant traumatic insults to other organs (MT).
Our purpose was to investigate the quality and morphology of cultured bovine lenses after exposure to hyperbaric oxygen (HBO) in the presence or absence of desferrioxamine (DFO) or zinc-desferrioxamine (Zn-DFO). Intact bovine lenses were cultured and exposed to HBO of 100% oxygen at 2.5 ATA for 120 min.

- The study investigated the impact of high partial pressure oxygen on lens quality and enzyme activities (catalase and Na, K-ATPase) in cultured bovine lenses, finding that exposure to hyperbaric oxygen significantly decreased lens optical quality and enzyme activities over a 14-day period.
- Adding zinc-desferrioxamine (Zn-DFO) before exposure to high oxygen levels largely prevented the damage, while later additions were less effective, indicating Zn-DFO provides a protective effect against oxidative stress.
- Overall, the research suggests that high oxygen exposure is harmful to lens structure and function, but the timing of Zn-DFO administration is crucial in mitigating these adverse effects, hinting at potential treatments
One medial triangular Tutoplast sling as a frontalis suspension for adult myogenic blepharoptosis.
Acta Ophthalmol Scand
February 2006
Purpose: The treatment of choice for medium to severe blepharoptosis with minimal or no levator function is frontalis suspension with a sling, using a rectangular or rhomboid sling placement technique. We describe the short-term, follow-up results of frontalis suspension surgery for adult myogenic blepharoptosis using Tutoplast, a commercially available fascia lata allograft.
Methods: We conducted a consecutive, interventional case study.
Background: Cataract is the leading cause of preventable blindness worldwide. Clinical observations and laboratory results have shown that oxygen has a possible toxic role in cataract formation.
Aim: The aim of the present study was to demonstrate, measure and characterize the damage caused to bovine lenses in organ culture as a result of their exposure to hyperbaric oxygen pressure.
Article Synopsis
- Essential blepharospasm is a progressive condition leading to a decreased quality of life, and while Botulinum toxin injections are common, some patients don't respond well or face complications.
- A study involving four patients undergoing sling frontalis suspension surgery showed significant improvements, with many being able to reduce or stop Botox treatments altogether.
- The findings suggest that sling frontalis suspension is a safe and effective alternative for treating essential blepharospasm, though more extensive research is necessary to confirm these results.
Purpose: To investigate a possible role of the haptoglobin phenotype in the development of exudative age-related macular degeneration (AMD) in human subjects.
Design: Prospective, observational, comparative population study.
Methods: The study was carried out in an institutional setting.
We report a case of a man who had undergone gold eyelid loading for lagophthalmos 22 years earlier. During examination for a complaint of foreign body sensation in the operated eye, the gold weight was found under the palpebral conjunctiva. Although extrusion of a gold weight through the skin anteriorly is well recognized, posterior extrusion has not been previously reported.
