    Our first experience with pascal grid laser photocoagulation in diabetic macular edema; [Diyabetik maküla ödeminde pascal grid lazer fotokoagülasyonu ile ilk tecrübelerimiz]
    (2011) Kayikçioǧlu O.; Seymenoǧlu G.; Zerdeci N.
    Purpose: To assess the efficacy and safety of patterned scan (Pascal) grid laser teratment in diffuse diabetic macular edema. Materials and Methods: Our study included 30 eyes of 25 patients with diffuse macular edema who were never treated before at our institution. All patients had detailed ophthalmologic examination at baseline and at 1, 3 and 6 months after treatment. Best corrected visual acuity (BCVA) was measured using Snellen chart and then converted to logMAR for statistical analysis. Macular thickness (MT) measurements were performed using spectral domain optical cohorence tomography at baseline and at every visit thereafter. Treatment was performed with Pascal system by using its specific grid pattern. Laser parameters and complications were recorded. Results: The mean age of the patients was 57.8±5.6 years. BCVA was 0.63±0.38 (logMAR) at baseline and 0.68±0.47 at 1 month, 0.64±0.47 at 3 months and 0.66±0.47 at 6 months after the treatment. MT was 370±164 μm at baseline and 383±180 μm at 1 month, 374±191 μm at 3 months and 356±196 μm at 6 months after the treatment. There was no statistically significant difference in BCVA and MT before and after the treatment in all visits. There was no complications recorded. Conclusion: Grid photocoagulation by the Pascal system is found to be safe in diffuse diabetic macular edema in short term follow up. BCVA and MT were maintained in all patients at the end of follow up. The efficacy of the treatment seems to be closely related with the metabolic control.

    Resolution of vitreomacular traction following intravitreal triamcinolone acetonide injection in an eye with branch retinal vein occlusion
    (Dove Medical Press Ltd, 2012) Seymenoǧlu G.; Kayikçioǧlu O.; Şahin B.O.
    A 60-year-old woman with a past medical history of branch retinal vein occlusion presented with decreased vision and metamorphopsia in her left eye. A fundus examination revealed a tortuous retinal vein with a few retinal hemorrhages in the inferotemporal quadrant. Optical coherence tomography revealed a partially separated posterior vitreous membrane pulling up the fovea. The patient refused surgical treatment so intravitreal triamcinolone acetonide (4 mg/0.1 mL) was administered. The patient reported resolution of symptoms in her left eye following this treatment, but her visual acuity did not show any improvement. Optical coherence tomography scanning revealed a complete detachment of the posterior hyaloid with release of the vitreomacular traction. In patients with vitreomacular traction and branch retinal vein occlusion, the combination of the possible vitreous liquefaction and mechanical increase of vitreous volume caused by an intravitreal injection with a degree of reduction in retinal thickness may play a role in the resolution of vitreomacular traction. © 2012 Seymenoǧlu et al, publisher and licensee Dove Medical Press Ltd.

    Evaluation of macula with optical coherence tomography in patients with decreased visual acuity after successful retinal detachment surgery; [Başarılı Regmatojen Retina Dekolmanı Ameliyatlarından Sonra Görme Rehabilitasyonunun Saǧlanamadıǧı Olgularda Makulanın Optik Koherens Tomografi ile Deǧerlendirilmesi]
    (Turkish Ophthalmology Society, 2012) Seymenoǧlu G.; Şahin B.Ö.; Top C.G.; Kayikçioǧlu O.; Başer E.
    Purpose: To study the foveal microstructural changes that may explain the incomplete visual recovery in eyes with anatomically successful repair of rhegmatogenous retinal detachments (RRD) using spectral-domain optical coherence tomography (OCT) and to evaluate the correlation between foveal changes and postoperative visual acuity. Material and Method: Forty-four eyes of 43 patients with macula-off RRDs were examined in our study. Patients were examined on first, third and sixth months postoperatively. The patients had a complete ophthalmological examination and OCT images were obtained at all postoperative visits. The postoperative OCT findings were classified in 4 groups: Group 1: continuous inner segment/outer segment (IS/OS) line, Group 2: disrupted IS/OS line, Group 3: epiretinal membrane (ERM), Group 4: residual foveal detachment. Results: Postoperative OCT findings showed that group 1 consisted of 19 eyes (43.2%), group 2 consisted of 15 eyes (34.1%), group 3 consisted of 7 eyes (15.9%) and group 4 consisted of 3 eyes (6.8%). The mean best-corrected visual acuity (BCVA) was significantly higher (p<0.001). Discussion: Spectral-domain OCT provides valuable information which helps the understanding of foveal microstructural changes and explains the possible causes of poor postoperative visual acuity in eyes with anatomically successful RRD repair.

    Comparison of pain response of patients undergoing panretinal photocoagulation for proliferati diabetic retinopathy: 532 nm standard laser vs. multispot pattern scan laser; [Proliferatif diyabetik retinopati nedeniyle panretinal fotokoagulasyon yapılan hastalarda aǧrı cevabının karşılaştırılması: 532 nm standart lazer vs multispot patern taramalı lazer]
    (Turkish Ophthalmology Society, 2013) Seymenoǧlu G.; Kayikçioǧlu O.; Başer E.; Sami Ilker S.
    Purpose: To compare pain response of patients undergoing panretinal photocoagulation (PRP) for proliferative diabetic retinopathy (PDR) using 532 nm standard laser versus multispot pattern scan laser and to evaluate the relationship between pain response and patient characteristics. Material and Method: Thirty-five patients had PRP with the Pascal system in a single session, while other 35 patients had PRP with conventional laser in 2 sessions. Parameters used in conventional laser were as follows: spot size 200 μm, exposure time 0.2 s, and power sufficient to produce visible grey-white burns. We used same spot size, 20-30 ms exposure time, and higher levels of laser power in order to get a similar endpoint in the Pascal system. The patients were required to evaluate the severity of pain on a visual analog scale (VAS) and verbally 5 minutes after PRP with Pascal and 5 minutes after the first session of PRP with conventional laser. The relationship between pain experienced and patient characteristics was evaluated. Results: At baseline, both groups did not differ significantly (p >0.05, for all) with respect to sex, age, duration of diabetes, most recent HbA1c, treatment regimen, or patient experience. The patients in the Pascal group had a mean pain score of 0.55±0.70 on verbal scale and 1.54±1.22 on VAS compared to 2.17±1.18 and 5.54±3.28, respectively in the conventional laser group which was, statistically, significantly different in both scales (p<0.05). Discussion: Our study confirms that new generation pattern scanning photocoagulators satisfactorily decrease the pain by shortening the exposure time while increasing the laser power.
