Aim. To compare the measurements of retinal nerve fiber layer (RNFL), macula and optic disc parameters obtained by optical coherence tomography (OCT), and intraocular pressure (IOP) between the patients with thyroid-associated ophthalmopathy (TAO) and healthy controls. Methods. One hundred and thirty-two eyes of 66 patients with TAO and 72 eyes of 36 healthy controls were included in the study. Proptosis level was determined by Hertel exophthalmometer. Optic disc, peripapillary retinal nerve fiber layer, and macula parameters were measured by OCT. All measurements of the patients were compared with those of age- and sex-matched healthy controls. Results. No statistically significant difference was found between the patients with TAO and control group in terms of demographic characteristics (P > 0.05). Exophthalmometer measurements and IOP were higher in TAO group (P < 0.05). Mean macula thicknesses in TAO and control groups were 239.3 ± 29.8 μm and 246.6 ± 31.8 μm, respectively, and the difference between the groups was statistically significant (P = 0.000). TAO group had thinner inferior RNFL thickness and macular thicknesses (superior, inferior, temporal, and nasal) and higher disc area and C/D ratio when compared with the control group (P < 0.05). Conclusion. IOP, disc area, and C/D area ratio were higher in the patients with TAO and the thicknesses of macula and inferior RNFL were thinner when compared with healthy controls. This trial is registered with registration number at clinicaltrials.gov NCT02766660.

The randomly selected control subjects consisted of 66 age matched patients with no retinal vein obstruction and no refraction default. Axial lengths were measured by the same person using the same technique.In patients with retinal vein occlusion the axial length of the affected eyes were compared with the other healthy unaffected eyes, and also with the control eyes. Statistical analyses were performed by paired t and Student's t tests.Statistical significance was considered as p<0.05. The means were given with their standard error (SEM) and difference between the two means were compared within the 95% confidence interval. ResultsOf the 17 patients with CRVO, 1 1 were women and six were men. Their ages ranged between 55 and 73 years with a mean of 63.87 (SEM

The purpose of this study was to investigate the effects of pupil dilation on the parameters of the AL-Scan (Nidek Co., Ltd, Gamagori, Japan). We compared the measurements of axial length (AL), anterior chamber depth (ACD), central corneal keratometry reading, pupil diameter, and intraocular lens (IOL) power of 72 eyes of 72 healthy volunteers and patients scheduled for cataract surgery before and 45 min after instillation of cyclopentolate hydrochloride 1 % using the AL-Scan. Intraobserver repeatability was assessed by taking three consecutive recordings of ACD and AL. Only ACD readings were significantly different between predilation and postdilation (P < 0.001). The difference of the other measurements between two sessions was not statistically significant (P > 0.001). Only two cases in the study demonstrated changes in IOL power higher than 0.5 D. The intraobserver repeatability of both devices was good (CV values for ACD and AL were 0.16 and 0.20 %, respectively). Dilated pupil size did not affect the measurement of IOL power using the A-Scan optical biometer, but increase in ACD after dilation should be taken into account when performing refractive surgeries in which ACD is very important such as phakic anterior chamber IOL implantation.

PurposeTo describe and identify ocular and wound characteristics, and prognostic factors associated with final visual acuity (VA) in patients with scleral rupture due to blunt ocular trauma.MethodsThe medical records of 61 patients with globe rupture due to blunt ocular trauma who underwent primary repair were reviewed retrospectively. The data recorded included demographic characteristics, initial and final VA, ocular signs, wound characteristics, and surgeries. Initial VA, ocular signs, wound characteristics, and surgeries were analyzed to determine the association with the final VA.ResultsForty three women and 18 men with a mean age of 43.6±23.5 years were included in the study. The locations of scleral wounds were mostly in the superonasal quadrant (41.0%) and zone 2 (75.4%). In eyes with hyphema (P=0.009), vitreous hemorrhage (P=0.001), and retinal detachment (P=0.004), final VA was statistically worse than eyes without these signs. A moderate positive correlation was found between the initial and final VA (P<0.001). Final VA was statistically worse in eyes with horizontal midline wounds than in eyes with vertical midline wounds (P=0.002). A moderate negative correlation was found between scleral wound length and final VA (P<0.001). Patients who underwent cataract surgery had statistically better final VA (P=0.002).ConclusionsScleral rupture was detected mostly in females, superonasal quadrant and zone 2. Poor final VA was significantly associated with poor initial VA, longer wound length, horizontal midline wound, presence of hyphema, vitreous hemorrhage and retinal detachment at presentation, and cataract surgery not performed during follow-up period. Scleral ruptures have different demographic, ocular and wound characteristics than other open globe injuries.

Twenty patients with primary open angle glaucoma who have been treated with identical antiglaucoma eye drops in both eyes were examined. Silicone punctal plugs were used to occlude the inferior punctum of one eye, in order to block the nasolacrimal canal. The intraocular pressures and effects of the medical therapy before and after punctal occlusion were compared. Punctal occlusion significantly decreased the intraocular pressure with an average of 2.00 +/- 0.43 mmHg in the plugged eyes (p < 0.001). The intraocular pressure in the unplugged control eyes did not change significantly (p > 0.05) after punctal occlusion of the fellow treated eye.

ABSTRACT.Purpose: Cyclosporine-A (CSA) combined with corticosteroid therapy was administered to 12 patients with severe Behçet's uveitis who were resistant to colchicine or cytotoxic therapy. Methods: Previous colchicine or cytotoxic therapies were tapered off one month before CSA therapy. All patients were started on an initial oral dose of 5 mg/ kg/day of CSA. After the first three months, the CSA dose was reduced to a maintenance dose according to the intraocular inflammatory response. Results: The average follow-up period was 20 (12-36) months. Visual acuity remained the same in 12 (%54.5) and improved in 8 (%36.4) eyes. There was a decrease in the frequency (p∞0.01) and severity (p∞0.01) of ocular attacks and in the maintenance steroid dose (p∞0.01) when compared with conventional therapy. The frequent side effects were paraesthesia-hyperesthesia, fatigue, nausea, hirsutism and dose-related nephrotoxicity in one patient. Conclusion:The results of the study suggest that low dose CSA combined with low dose corticosteroid may be an effective therapeutic alternative in the treatment of severe refractory Behçet's uveitis.

There are no specific treatment protocols for papillophlebitis, which is basically a central retinal vein occlusion (CRVO) occurring in young adults. The present report is that of a 14-year-old girl, who presented with blurred vision in her right eye. Although her visual acuity (VA) was initially 20/20, there were venous engorgements, blurry disc margins, and a substantial collection of subretinal fluid. She was diagnosed with papillophlebitis. When, 2 weeks later, her VA had decreased to 20/200, she was administered intravitreally injected ranibizumab. One week post-injection, her VA had returned to normal (20/20) and the subretinal fluid had diminished markedly. Intravitreal ranibizumab injection appears to be an effective treatment modality for this condition.
