Materials and methods: A total of 80 patients with COPD (80 eyes) and 50 control subjects (50 eyes) were enrolled. Choroidal scans and the retinal nerve fiber layer (RNFL) thickness were obtained for all eyes using OCT. Results: The average peripapillary choroidal thickness measurements of the COPD group (147.58 ± 53.53 μm) were lower than the control group (160.84 ± 44.73 μm) (p = 0.068). Inferior segment thicknesses were significantly thinner than the other segments (p < 0.05). Subfoveal choroidal thickness and RNFL thickness measurements of the COPD group were also lower than those of the control group (p = 0.111). Conclusion: Hypoxia in COPD seems to affect the choroidal thickness. Thinning of the choroid may be attributed to increased vascular resistance and reduced blood flow in patients with COPD. The possible effects of the disease to the eye may be clarified through the role of the choroidal vasculature in the blood supply of the anterior optic nerve head.

Twenty-nine eyes of 29 patients with tilted optic discs were studied with spectral-domain (SD)-OCT and compared with age and sex-matched control subjects in a prospective design. The imaging of RNFL was performed using circular scans of a diameter of 3.4 mm around the optic disc using OCT. For measurements of peripapillary choroidal thickness, the standar d protocol for RNFL assessment was performed. SD-OCT indicated significantly lower superotemporal (p<0.001), superonasal (p=0.001), and global (p=0.005) RNFL thicknesses in the tilted disc group than those of the control group. Peripapillary choroid was significantly thicker at the site of the elevated rim of eyes with tilted disc (p<0.001). This study demonstrated a clinical characterization of the main tilted disc morphologies that may be helpful in differentiating a tilted disc from other altered disc morphologies. Further studies are recommended to study the comparison between glaucoma and tilted disc groups.

In cases with decreased visibility because of excessive bleeding during surgery, a small sac size, and difficulty of mutual suturing between nasal mucosal and sac flaps related to distance. This retrospective study included 118 patients with a nasolacrimal duct obstruction who underwent the modified technique of EDCR. The modified EDCR procedure envisions the creation of anastomosis of the single anterior "U"-shaped flaps suturing anterior flaps of the lacrimal sac and nasal mucosa. The sutured flap was fixed on to the orbicularis muscle. The silicone tube intubation was performed on all patients. The average age of the patients was 39 ± 19.2 (9-70) years, including 94 women and 24 men. The average follow-up time was 18 ± 4.5 (9-36) months. Total 112 eyes...

The decrease in IO P values of the 1 st week, 1 st month, 3 rd month, 6 th month, and 1 st year was statistically significant, but that of the 2 nd year was not significant. The increase in ACD and ICA values of the 1 st week, 1 st month, 3 rd month, 6 th month, and 1 st year was statistically significant, but that of the 2 nd year was not significant. The increase in CCT values of 1 st week and 1 st month was statistically significant, but those of 3 rd month, 6 th month, 1 st year, and 2 nd year were not significant. In conclusion, phacoemulsification surgery decreases IOP and increases ACD and ICA in the short-term. However, in the long-term it does not cause any significant changes.

We retrospectively evaluated the data of 43 eyes of 28 consecutive patients (12 males, 16 females) with cataract and high myopia who had undergone phacoemulsification and intraocular lens (IOL) implantation. The mean [± standard deviation (range)] age of the patients was 59.20 ± 11.08 (39-77) years. The frequency of nuclear cataract was significantly higher than that of other cataract types (P=0.003). The mean axial length was 28.97 ± 1.99 (26-33) mm and the mean IOL power was 5.09 ± 4.78 (-3.0 to +14.0) diopters (D). The mean preoperative spherical equivalent (SE) was -16.48 ± 5.23 (-8.00 to -25.00) D and the mean postoperative SE was -1.46 ± 0.93 (0.00 to -3.00) D (P=0.00). The mean preoperative best-corrected visual acuity (BCVA) was 0.91 ± 0.37 (0.30 to -1.50) logMAR and the mean postoperative BCVA was 0.29 ± 0.25 (0.00-1.00) logMAR (P=0.00). Twenty-two eyes (51.2%) achieved the target postoperative refraction (±1.0 D). The eyes were divided into 3 groups according to the axial length. The mean biometric error was significantly higher in the group with the greatest axial length than in the other groups (P=0.007). Preoperative argon laser photocoagulation was performed in 7 eyes (16%) on account of retinal tears, retinal holes, or lattice degeneration. Postoperatively, retinal tears developed in 2 eyes (4%) and were treated with photocoagulation. One eye (2%) developed retinal detachment postoperatively, with the patient consequently referred for retinal surgery. Postoperatively, posterior capsule opacities developed in 11 eyes (25%), with all cases treated by laser capsulotomy. Good postoperative outcomes following phacoemulsification surgery were observed in patients with cataract and high myopia. However, clinicians should be aware of the risk of postoperative retinal tears and rhegmatogenous retinal detachment. Preoperative prophylactic argon laser photocoagulation treatment should be considered where necessary.

Research paper thumbnail of The influence of size and shape of Nd:YAG capsulotomy on visual acuity and refraction

We retrospectively evaluated 85 eyes of 67 patients treated with Nd:YAG laser posterior capsulotomy for posterior capsule opacification (PCO). The mean age of included patients was 57.57 ± 9.26 (mean ± standard deviation, 38-75 years). The mean interval between surgery and Nd:YAG laser capsulotomy was 26.09 ± 7.08 (10-38) months. Patients were divided into four groups according to the shape and size of capsulotomy. Groups comprised patients with cruciate shape capsulotomies with openings of less than or equal to 3.5 mm (Group 1) or greater (Group 2) and patients with circular shape capsulotomies with openings of less than or equal to 3.5 mm (Group 3) or greater (Group 4). The mean number and energy of laser firings were significantly higher in Group 4 (p=0.00), and significantly lower in Group 1 (p=0.00), compared with that in other groups. Pre-procedural and post-procedural mean spherical equivalent (SE) values were significantly higher in Group 1 (p=0.026 and p=0.011, respectively). No statistical difference in best-corrected visual acuities (BCVA) or intraocular pressures (IOP) were observed between groups before (p=0.44 and p=0.452, respectively) or after capsulotomy (p=0.108 and p=0.125, respectively). A significantly higher number of patients in Group 4 (p=0.001), and a significantly lower number of patients in Group 1 (p=0.001), reported floating bodies compared with that in other groups. No significant changes in SE or intraocular pressure were observed after capsulotomy in any group (p=0.074 and p=0.856, respectively). Best-corrected visual acuity was significantly improved following capsulotomy in all groups (p<0.01). Cruciate shape capsulotomy with an opening of 3.5 mm or less provides the greatest improvement in visual function with minimal complications.

For measurements of peripapillary choroidal thickness, the standar d protocol for RNFL assessment was performed. SD-OCT indicated significantly lower superotemporal (p<0.001), superonasal (p=0.001), and global (p=0.005) RNFL thicknesses in the tilted disc group than those of the control group. Peripapillary choroid was significantly thicker at the site of the elevated rim of eyes with tilted disc (p<0.001). This study demonstrated a clinical characterization of the main tilted disc morphologies that may be helpful in differentiating a tilted disc from other altered disc morphologies. Further studies are recommended to study the comparison between glaucoma and tilted disc groups.

In cases with decreased visibility because of excessive bleeding during surgery, a small sac size, and difficulty of mutual suturing between nasal mucosal and sac flaps related to distance. This retrospective study included 118 patients with a nasolacrimal duct obstruction who underwent the modified technique of EDCR. The modified EDCR procedure envisions the creation of anastomosis of the single anterior "U"-shaped flaps suturing anterior flaps of the lacrimal sac and nasal mucosa. The sutured flap was fixed on to the orbicularis muscle. The silicone tube intubation was performed on all patients. The average age of the patients was 39 ± 19.2 (9-70) years, including 94 women and 24 men. The average follow-up time was 18 ± 4.5 (9-36) months. Total 112 eyes...

The decrease in IO P values of the 1 st week, 1 st month, 3 rd month, 6 th month, and 1 st year was statistically significant, but that of the 2 nd year was not significant. The increase in ACD and ICA values of the 1 st week, 1 st month, 3 rd month, 6 th month, and 1 st year was statistically significant, but that of the 2 nd year was not significant. The increase in CCT values of 1 st week and 1 st month was statistically significant, but those of 3 rd month, 6 th month, 1 st year, and 2 nd year were not significant. In conclusion, phacoemulsification surgery decreases IOP and increases ACD and ICA in the short-term. However, in the long-term it does not cause any significant changes.

We retrospectively evaluated the data of 43 eyes of 28 consecutive patients (12 males, 16 females) with cataract and high myopia who had undergone phacoemulsification and intraocular lens (IOL) implantation. The mean [± standard deviation (range)] age of the patients was 59.20 ± 11.08 (39-77) years. The frequency of nuclear cataract was significantly higher than that of other cataract types (P=0.003). The mean axial length was 28.97 ± 1.99 (26-33) mm and the mean IOL power was 5.09 ± 4.78 (-3.0 to +14.0) diopters (D). The mean preoperative spherical equivalent (SE) was -16.48 ± 5.23 (-8.00 to -25.00) D and the mean postoperative SE was -1.46 ± 0.93 (0.00 to -3.00) D (P=0.00). The mean preoperative best-corrected visual acuity (BCVA) was 0.91 ± 0.37 (0.30 to -1.50) logMAR and the mean postoperative BCVA was 0.29 ± 0.25 (0.00-1.00) logMAR (P=0.00). Twenty-two eyes (51.2%) achieved the target postoperative refraction (±1.0 D). The eyes were divided into 3 groups according to the axial length. The mean biometric error was significantly higher in the group with the greatest axial length than in the other groups (P=0.007). Preoperative argon laser photocoagulation was performed in 7 eyes (16%) on account of retinal tears, retinal holes, or lattice degeneration. Postoperatively, retinal tears developed in 2 eyes (4%) and were treated with photocoagulation. One eye (2%) developed retinal detachment postoperatively, with the patient consequently referred for retinal surgery. Postoperatively, posterior capsule opacities developed in 11 eyes (25%), with all cases treated by laser capsulotomy. Good postoperative outcomes following phacoemulsification surgery were observed in patients with cataract and high myopia. However, clinicians should be aware of the risk of postoperative retinal tears and rhegmatogenous retinal detachment. Preoperative prophylactic argon laser photocoagulation treatment should be considered where necessary.

We retrospectively evaluated 85 eyes of 67 patients treated with Nd:YAG laser posterior capsulotomy for posterior capsule opacification (PCO). The mean age of included patients was 57.57 ± 9.26 (mean ± standard deviation, 38-75 years). The mean interval between surgery and Nd:YAG laser capsulotomy was 26.09 ± 7.08 (10-38) months. Patients were divided into four groups according to the shape and size of capsulotomy. Groups comprised patients with cruciate shape capsulotomies with openings of less than or equal to 3.5 mm (Group 1) or greater (Group 2) and patients with circular shape capsulotomies with openings of less than or equal to 3.5 mm (Group 3) or greater (Group 4). The mean number and energy of laser firings were significantly higher in Group 4 (p=0.00), and significantly lower in Group 1 (p=0.00), compared with that in other groups. Pre-procedural and post-procedural mean spherical equivalent (SE) values were significantly higher in Group 1 (p=0.026 and p=0.011, respectively). No statistical difference in best-corrected visual acuities (BCVA) or intraocular pressures (IOP) were observed between groups before (p=0.44 and p=0.452, respectively) or after capsulotomy (p=0.108 and p=0.125, respectively). A significantly higher number of patients in Group 4 (p=0.001), and a significantly lower number of patients in Group 1 (p=0.001), reported floating bodies compared with that in other groups. No significant changes in SE or intraocular pressure were observed after capsulotomy in any group (p=0.074 and p=0.856, respectively). Best-corrected visual acuity was significantly improved following capsulotomy in all groups (p<0.01). Cruciate shape capsulotomy with an opening of 3.5 mm or less provides the greatest improvement in visual function with minimal complications.
