Effects of 1% cyclopentolate hydrochloride on anterior segment parameters obtained with Pentacam in young adults

Purpose: To investigate the effects of topically applied 1% cyclopentolate hydrochloride on anterior segment parameters obtained with a Pentacam rotating Scheimpflug camera in healthy young adults. Methods: Anterior segment analyses of 25 eyes from 25 young adults (Group 1), before and after 45 min of 1% cyclopentolate hydrochloride application, were performed. For a control group (cycloplegia-free, Group 2), 24 eyes of 24 age- and sex-matched healthy cases were evaluated twice at 45 min intervals. The results obtained from the groups were compared statistically. Results: The mean ages of the groups were 23.04 ± 3.42 (range, 18-29) and 22.4 ± 2.05 (range, 18-27) years for Groups 1 and 2, respectively (p=0.259). In Group 1, measurements between the two analyses were significantly different for the values of anterior chamber depth (ACD), anterior chamber angle (ACA), and anterior chamber volume (ACV) (p<0.05), whereas no statistical difference was found for the central corneal thickness (CCT) and keratometry (K1, K2) measurements. In Group 2, none of these parameters were statistically different between the two analyses. Conclusions: Topically applied 1% cyclopentolate hydrochloride caused an increase in the ACD and ACV values, and a decrease in the ACA value. However, it had no significant effect on the CCT and keratometry measurements. It is important to consider these effects when using the Pentacam device on young adults with cycloplegia and when applying it for various reasons

Wound Dehiscence and Iris Prolapse Through Side-Port Incision 5 Years After Phacoemulsification Surgery: Case Repor

A 65-year-old man was referred to our institution for the evaluation of redness in the right eye. The patient sustained a blunt trauma 10 days previously and had a history of bilateral uncomplicated phacoemulsification performed 5 years earlier. His examination revealed iris prolapse through the side-port incision in the right eye. The patient underwent wound and iris repair. Our case report demonstrates that small sized clear corneal incisions used in cataract surgery have a risk for development of late traumatic wound dehiscence. To the best of our knowledge, late iris prolapse from a side-port incision have not been reported before. We believe that advanced corneal incision configurations with femtosecond laser systems may decrease the risk of similar complications in the future. (Turk J Ophthalmol 2013; 43: 55-6

A Case of Brown-McLean Syndrome

A 89-year-old man with a history of cataract surgery ten years ago presented to our ophthalmology department with blurred vision. On ophthalmic examination, best-corrected visual acuity was 20/50 in the right eye and 20/32 in the left. Slit lamp examination revealed bilateral symmetrical peripheral corneal oedema, advanced at the inferior part of the cornea in both eyes. Considering clinical and confocal microscopy findings, a diagnosis of Brown-McLean Syndrome (BMS) was made. BMS is a rare condition that may developed after cataract surgery, and it can be easily overlooked or misdiagnosed. Our report points to this rare syndrome and we tried to emphasis the importance of BMS considering it in the differential diagnosis of refractory peripheral corneal oedema developed in pseudophakic patients.

Another Risk From Cigarette Smoking: Corneal Burn

A 21-year-old male presented with corneal injury in his left eye after one of his friends had moved his arm backwards and accidentally hit his eye with the lit end of a cigarette. Slit lamp examination revealed epithelial defect and significant stromal edema at the superior temporal quadrant of the cornea. Cigarette ashes were noted in his lashes and inferior conjunctival fornix at the initial examination in the emergency service. 6 weeks after the injury, slit lamp examination revealed stromal thinning and haze in the temporal part of the cornea. His best spectacle-corrected distance visual acuity was 20/25 with a refractive error of -6.75x135 diopters in the left eye. Our case demonstrates that ocular thermal injury due to cigarette smoking can cause serious damage to the ocular tissues. (Turk J Oph thal mol 2012; 42: 484-5

Abducens Palsy Due to Cerebral Venous Sinus Thrombosis in a Patient with Heart Failure

Cerebral venous sinus thrombosis has a wide spectrum of presentation. The clinical manifestation depends on the location of the thrombus, its rate of progression, and the extent of venous collateralization. In this case report, we present the findings of cerebral venous sinus thrombosis presenting with abducens palsy and papilloedema in a patient with heart failure, an unusual etiology for cerebral venous sinus thrombosis.

Repeatability and Comparison of Keratometry Values Measured with Potec PRK-6000 Autorefractometer, IOLMaster, and Pentacam

Objectives: To research the repeatability and intercompatibility of keratometry values measured with Potec PRK-6000 autorefractometer, IOL Master, and Pentacam. Materials and Methods: In this prospective study, consecutive measurements were performed in two different sessions with the mentioned three devices on 110 eyes of 55 subjects who had no additional ocular pathology except for refraction error. The consistency of flat and steep keratometry, average keratometry, and corneal astigmatism values obtained in both sessions was compared by using intraclass correlation coefficient (ICC). The measurement differences between the devices were statistically compared as well. Results: The mean age of the study subjects was 23.05±3.01 (18-30) years. ICC values of average keratometry measurements obtained in the sessions were 0.996 for Potec PRK-6000 autorefractometer, 0.997 for IOL Master, and 0.999 for Pentacam. There was high compatibility between the three devices in terms of average keratometry values in Bland-Altman analysis. However, there were statistically significant differences between the devices in terms of parameters other than corneal astigmatism. Conclusion: The repeatability of the three devices was found considerably high in keratometry measurements. However, it is not appropriate for these devices to be substituted for each other in keratometry measurements. (Turk J Ophthalmol 2014; 44: 179-83
