Prostaglandin-associated periorbitopathy is as common as other adverse effects when careful examinations are performed and is more frequent and more severe in bimatoprost users. The loss of the periorbital fat pad is the first sign to occur during the evolution of prostaglandin-associated periorbitopathy, especially in older patients.

Although frequency of ROP in Turkey is similar to that in the United States, the rate of severe ROP necessitating treatment seems to be higher in Turkey. Neonates with a gestational age of 32 weeks or less, a birth weight of less than 1,250 g, sepsis, and oxygen therapy may have a greater risk of developing ROP and screening should be intensified in the presence of these risk factors.

Purpose:To report the management outcomes of diplopia in patients with blowout fracture.Materials and Methods:Data for 39 patients with diplopia due to orbital blowout fracture were analyzed retrospectively. The inferior wall alone was involved in 22 (56.4%) patients, medial wall alone was involved in 14 (35.8%) patients, and the medial and inferior walls were involved in three (7.6%) patients. Each fracture was reconstructed with a Medpore® implant. Strabismus surgery or prism correction was performed in required patients for the management of persistent diplopia. Mean postoperative follow up was 6.5 months.Results:Twenty-three (58.9%) patients with diplopia underwent surgical repair of blowout fracture. Diplopia was eliminated in 17 (73.9%) patients following orbital wall surgery. Of the 23 patients, three (7.6%) patients required prism glasses and another three (7.6%) patients required strabismus surgery for persistent diplopia. In four (10.2%) patients, strabismus surgery was performed without fracture repair. Twelve patients (30.7%) with negative forced duction test results were followed up without surgery.Conclusions:In our study, diplopia resolved in 30.7% of patients without surgery and 69.2% of patients with diplopia required surgical intervention. Primary gaze diplopia was eliminated in 73.9% of patients through orbital wall repair. The most frequently employed secondary surgery was adjustable inferior rectus recession and <17.8% of patients required additional strabismus surgery.

Purpose To document the characteristics, treatments, and anatomical and functional outcomes of patients with ocular trauma from improvised explosive devices (IEDs). Methods Retrospective review of ocular injuries caused by IEDs, admitted to our tertiary referral centre. Results In total, sixty-one eyes of the 39 patients with an average age of 24 years (range, 20-42 years) were included in the study. In total, 49 (80%) eyes of the patients had open-globe and 12 (20%) had closed-globe injury.In eyes with open-globe injury, intraocular foreign body (IOFB) injury was the most frequently encountered type of injury, observed in 76% of eyes. Evisceration or enucleation was required as a primary surgical intervention in 17 (28%) of the eyes. Twentytwo (36%) eyes had no light perception at presentation. Patients were followed up for an average of 6 months (range, 4-34 months). At the last follow-up, 26 (43%) of 61 eyes had no light perception. Postoperative proliferative vitreoretinopathy (PVR) developed in 12 (50%) of the 24 eyes that underwent vitreoretinal surgery, and four of these eyes became phthisical. There were no cases of endophthalmitis. The presence of open-globe injury and presenting visual acuity worse than 5/200 were significantly associated with poor visual outcome (o5/200, Po0.05).In eyes with open-globe injury, the presence of an IOFB was not associated with poor visual outcome (P40.05). Conclusion Ocular injuries from IEDs are highly associated with severe ocular damage requiring extensive surgical repair or evisceration/enucleation. Postoperative PVR is a common cause of poor anatomical and visual outcome.

The purpose of this study is to determine the effects of different anterior capsulotomy techniques and intraocular lens (IOL) types on IOL tilt and decentration. For this purpose the device using Purkinje reflections and photographic documentation were evaluated. A total of 107 cataractous eyes undergoing IOL implant surgery were divided into four groups based on the type of IOL and capsulotomy: group 1, single-piece polymethylmethacrylate (PMMA) IOL with a haptic distance of 13.50 mm; group 2, single-piece PMMA IOL with 12.0 mm overall lenght; group 3, three-piece foldable acrylic IOL with 13.00 mm PMMA haptic distance; group 4, the same IOL as group 1. While continuous circular capsulorhexis was the type of capsulotomy in the first three groups, envelope capsulotomy was used in group 4. Mean tilt and decentration were significantly less when capsulorhexis technique was used in comparison with envelope capsulotomy. Mean tilt of group 1 (2.83±0.89 degrees) and mean decentration of group 2 (0.28±0.14 mm) were higher within the first three groups. The differences regarding both the IOL decentration and tilt between the first three groups were statistically significant. This study shows that if the IOLs were placed properly in the capsular bag after continuous circular capsulorhexis, foldable acrylic IOLs with PMMA haptics are superior in terms of tilt and decentration.
